For the demonstration, we will use the production.products and production.categories tables from the sample database: The following query finds the number of products for each product category: Here is the output: Our goal is to turn the category names from the first column of the output into multiple columns and count the number of products for each category name as the following picture: In addition, we can add the model year to group the category by model year as shown in the following output: The pre-deployment script is located in PreDeployment.sql. Custom header(s), column names are separated by a comma. Calling a stored procedure always should begin with keyword EXEC, Do we specify custom headers with transposing. What to show in the new columnsThe value in the new columns must be an aggregate. The solution source code can be found on GitHub here. It is worth exploring and using in solving practical problems. The project uses .NET 2.0. Many developers just want to ’rotate’, pivot or transpose a result as if it were a matrix. (6576, 6711, 6935, 7440, 7855, 8201, 8455, 8770, 9011, 9353, 9570). A SQL Server table is a slightly different structure, where rows and columns are not equivalent and interchangeable. Standardize team-based development - Prevent rework and conflicts, build consistency and quality into your code, and gain time for development that adds value, with standardized best practices for database development. Another possibility, as you might guess, is to use .NET. This class cannot be inherited. How to create a pivot query in sql server without aggregate function. SQL  Apr 18, 2014 Apr 18, 2014 / By Mohamed El-Qassas / Microsoft SQL Server, SQL Server 2008, SQL Server 2012 / Convert Rows to columns using 'Pivot' in SQL Server when columns are string data type, convert the structure of the table data into a PIVOT, Pivot table without using Aggregiate function, Pivot with out aggregate, ROW_NUMBER() OVER. There are many situations in which the results of a query look better when they are rotated. There are a few things to write about the solution. All code connected with transposing the DataTable is located in TableManipulation.cs. However, to accomplish such a task of transposing without aggregation, you have to process your results row by row. In either case, you will need to modify the @Path and @Password variables for your environment. Lets say, there are values in different columns within a table and you want to perform some aggregations on those columns combining them all together or you may want them in a row … In order to explore the solution, start up Visual Studio Community Edition (or any kind of licensed edition). It returns each product on a new row, so orders with multiple products have multiple rows, 5 products max. For those who are new to .NET, a Dataset should be considered as a table collection. Many thanks for all the high quality answers. SendResultStart comes in a pair with SendResultEnd. Without Phil, I would never start investigating how to do transposing the query result. (25119, 25002, 25109, 23860, 22957, 23518, 23330, 22926, 23365, 23418, 23644). WHERE SalesOrderId >= @salesId1 AND SalesOrderId <= @salesId2; '@salesId1 int=43665,@salesId2 int=43671', --EXEC MATRIX.TRANSPOSING @query = 'SELECT * FROM sys.databases'. SSMS has powerful capabilities to copy the result and paste, for example, into an Excel file. In the solution, there are two kinds of transformations which are determined by the parameter @keyValueOption. (NOTE: The column is name.). The pivot column is the point around which the table will be rotated, and the pivot column values will be transposed into columns in the output table. The solution has some limitations. It doesn’t flip everything as shown here. For example, when you execute the simple T-SQL SELECT * FROM sys.databases to get all databases on the current SQL Server instance, the results look better somehow rotated. The query and its parameters are passed as parameters to the MATRIX.Transposing stored procedure. !-------, --------------------------------------------------------------------------------------, 'CREATE ASYMMETRIC KEY [askTransposingMatrix]', FROM ASYMMETRIC KEY askTransposingMatrix', GRANT UNSAFE ASSEMBLY TO [loginTransposingMatrix];', --remember that these are the column names of the original table. SQL allows the user to store more than 30 types of data in as many columns as required, so sometimes, it becomes difficult to find similar data in these columns. This is extremely important for understanding the performance of the stored procedure. The pre-deployment script, named PreDeployment.sql, first creates the MATRIX schema and then depending on SQL Server version (only for SQL Server 2017+), it creates an asymmetric key based on the solution snk file. The XML version of the script addresses this limitation by using a combination of XML Path, dynamic T-SQL and some built-in T-SQL functions such as STUFF and QUOTENAME. I need to convert this report into one which has a single row for each order. In the article, Multiple Options to Transposing Rows into Columns, I covered various options available in SQL Server to rotating a given row into columns. If you set @keyValueOption to 0, @columnMapping is ignored, and the result will look like the image below. A row represents an entity, and a column an attribute of an entity. Outlined in red is the project properties. Step 1: Create the test table. Transposing data does not involve aggregations. It uses an almost classic ADO.NET approach. What these defining values are 3. In this article, Darko Martinovic shares another method using a SQLCLR stored prodedure. For those who do not want to play with .NET source code, there is a ZIP file in the attachment of the article. If you woul like to clean up your environment after playing with this solution, there is a script for this purpose, located in Setup directory as well as in the attachment of the article. So, let us get back to the main topic. The latest one, An Easier Way of Pivoting Data in SQL Server, inspired me to start exploring another option to transpose a result from a query. Open Setup.sql in SSMS, just press F5, and the solution is deployed. The examples in this article will use the AdventureWorks2014 database. Similarly, there is a post-deploy script that is executed after the assembly is published. for this you can use scripts shown below Step 2: After executing the script. It appears that your VAL column is a varchar so you will have to use either the select sbno, Test1, Test2, Test3 from ( select test_name, sbno, val from yourtable ) d pivot ( max(val) for test_name in (Test1, Test2, Test3) ) piv; See SQL Fiddle with Demo. The XML option to transposing rows into columns is basically an optimal version of the PIVOT in that it addresses the dynamic column limitation. An application domain is a construct in the Microsoft .NET Framework common language runtime (CLR) that is the unit of isolation for an application. Query or stored procedure, which result we will transpose. in our case column [countryName] is containing same value so data will be partitioned by this column- see the imag… Yes, I learned a lot about JSON support in SQL Server from his article, but that didn’t keep me from exploring other possibililties. This class cannot be inherited. Thanks, Jay In this blog, we'll discuss converting values of rows into columns (PIVOT) and values of columns into rows (UNPIVOT) in MS SQL Server. SQL: Transpose rows to columns without aggregate function, Still an aggregation, but you can use a simple CASE statement per value, grouping by [date], [file] to get one row per combination; SELECT [file] Transpose rows and columns with no aggregate. In SQL Server 2017, there is a new instance level setting named clr strict security. Although SQLCLR seems to be a second-class citizen on SQL Server, there are situations when could replace T-SQL. America],[Total Europe & Eurasia], [Total Middle East],[Total Africa],[Total Asia Pacific]'. In our case column [countryName] has common values- see the image for this Step 4: Once you have found the column name containing same value . This gives the users the ability to transpose columns from a SQL Server table easily and create reports as per the requirements. To transpose table ‘Person.Person’ which has about 20K records, you will get the warning like in the image below. You can see the result in the image below. SQL Server has a PIVOT relational operator to turn the unique values of a specified column from multiple rows into multiple column values in the output (cross-tab), effectively rotating a table. SqlPipe allows managed stored procedures running in process in a SQL Server database to return results to the caller. I want to dynamically convert rows into columns. The stored procedure takes several parameters. Therefore, if you would like to transpose the results of your query, you will run a query like that in the listing below once the solution is in place. your table will look like this: Step 3: Now find a column in your table which has common value. To obtain the context connection, you must use the context connection string keyword. There is, of course, a lot of difference between a pivot and a transpose because columns in a SQL Table represent the discrete values of entities, not values in a range. In my opinion, it is a bug in SSMS. It must be executed before the assembly is published. The result of SELECT * FROM sys.databases is displayed in the image below. It seems that SSMS is a little bit confused when has to display SQLCLR stored procedure parameters. In this spot, I have to make a small digression and describe the term of an application domain. Converting columns into rows in SQL Server is not a new thing, we often face this kind of scenarios. However, sometimes the nat… Such a mandatory requirement is usually not an issue as most aggregations and subsequent pivoting is performed against fields of numeric data type. Fortnightly newsletters help sharpen your skills and keep you ahead, with articles, ebooks and opinion to keep you informed. Phil’s articles are not just educational but also inspiring. The key point here was to pass a @tableName parameter. This process of loading an application domain takes time (this is a performance penalty). In the first statement the @Rco value is 0 and in the second statement is 1. (2917, 2928, 3063, 3236, 3315, 3486, 3413, 3579, 3678, 3763, 3888), (24569, 25157, 26035, 25900, 26244, 27954, 28893, 30001, 30588, 31119, 32444). ) According to Microsoft documentation, the context connection allows you to execute T-SQL statements in the same context that was used when your code was invoked in the first place. When you transpose the original data and produce another table, the code must send the results. I am using Visual Studio 2017, but the solution works fine with Visual Studio 2013 as well. SendResultRow, as the name implies, sends a single row of data back to the client. The name values now become the column names. [Total S. & Cent. SendResultStart marks the beginning of a result set to be sent back to the client and uses the record parameter to construct the metadata that describes the result set. Yes, you can use a cursor or maybe you can accomplish this task by using an XML transformation. 'SELECT SalesOrderID , salesordernumber , purchaseordernumber , OrderDate , ShipDate , SubTotal , TaxAmt , TotalDue. You can notice in the image below that in the first case the header is formed based on the database name. When a user asks for some functionality located in your assembly the first time, an application domain is created. This statement queries sys.objects and sys.parameters filtering by the stored procedure name. The whole task is accomplished by utilizing the SqlPipe class. The result will look similar to what is shown in the image below. If we like to save result into permanent table or temp table. The column on which rotation will take place after running the new code  is outlined with red. The first and the second T-SQL statement differ by the @Rco parameter. SQLCLR uses application domains to isolate execution of .NET code on a per database and per assembly owner basis. Then it creates a login and grants the unsafe assembly permission to that login. --    ,@tableName = N'MATRIX.PERMANENT'; An Easier Way of Pivoting Data in SQL Server, Creating Templates with Liquid in ASP.NET Core, Cross-origin resource sharing for cross-site cookie-based authentication, An Easier Way of Transposing Query Result in SQL Server, Copyright 1999 - 2020 Red Gate Software Ltd. Maybe, in the future, I will remove this limitation and create some configuration table in which users can decide what is a maximum number of rows to transpose. (NOTE: I am using the words transpose and rotation interchangeably as synonyms throughout the article.). In the image below, I outlined the mandatory parameter in red. For example, count, sum, min, etc. You can see that the @Query parameter is the only one that does not have a default value. The first row, from the earlier test, is now the header of our table. You can see the entire script in the listing below. This setting requires strong signing assembly, and that was not the case prior SQL Server 2017 version if we marked the project as SAFE. The IN clause also allows you to specify an alias for each pivot value, making it easy to generate more meaningful column names. In the script, the table is filtered passing two parameters and the WHERE clause. I like Phil Factor’s articles. Run the following T-SQL query in order to check to see if there is a default value associated with the other parameters. You are probably asking yourself if the solution limited to newest SQL Server version? In the file, you can find two T-SQL scripts. It means you get the table with 1000 columns. Oracle Database 11g introduced the pivot operator. Of course, there is the PIVOT statement, but it doesn’t quite accomplish the task. Some pivot tables are also created to help in data analysis, mainly for slicing and dicing with the data and generate analytical queries after all. The results are shown in the image below. One of the options included the use of a PIVOT relational operator. The latest one, An Easier Way of Pivoting Data in SQL Server, inspired me to start exploring another option to transpose a result from a query. Please see the attached screen shot showing the format I have and the one that is needed. Place a pivot clause containing these items after the table name, like so:So to c… Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Parallel Data Warehouse You can use the PIVOT and UNPIVOT relational operators to change a table-valued expression into another table.PIVOT rotates a table-valued expression by turning the unique values from one column in the expression into multiple … The code that pipes the data table to the client is located in PipeUtilities.cs. After deploying the solution from VS or running setup.sql, your database model will be extended with a newly created stored procedure named MATRIX.Transposing (NOTE: MATRIX is the database schema). If you notice, Marketing has got two rows, one for each of the employee’s within that department, and the same is the case for Research and Development and Accounting and Finance. I have a CTE with the name T which holdS dates like: UserId tempStoredDate-----3 2012-12-01 5 2012-12-02 1 2012-12-03 4 2012-12-04 7 2012-12-05 I have a Employee table: (EMP_ID INT P.K, EMP_NAME VARCHAR(50)) I have an Attendance table which holds attendance dates marked by employees: (DetailsId int P.K, EMP_ID F.K, … The mandatory requirement of the operator is that you must supply the aggregate function with only a numeric data type. Group By in SQL helps us club together identical rows present in the columns of a table. T-SQL does not have an easy way to transpose a row and a column. Attentive readers will notice that some parameters do not show a default value in SSMS, which is opposite to my statement that only one parameter is mandatory. To use this you need three things: 1. In the second case, the header is formed based on database ID. (NOTE: To run it, you must install objects from his article.). In my opinion, the results look better rotated if the number of columns is greater than the number of rows. To do this, execute the T-SQL script in the listing below. One is for deploying the solution named Setup.sql and the other is for cleaning the environment after playing with the solution named CleanUp.sql. Furthermore, the results could be saved into a temporary table or permanent table as is shown in the listing below. The key point here is to pass @columnMapping as a new table header and to set @keyValueOption to 1. First is invoked SendResultsStart. Also, to conclude the part of sending the result back to the client, SqlDataRecord represents a single row of data and its metadata. Now back to the main topic: in the table below, each parameter is explained in detail. Execute the T-SQL script in the listing below. SSMS performs well when displaying standard T-SQL stored procedure parameters. SQL pivot multiple columns without aggregate. Yes, the @Query parameter is the query whose results we would like to transpose. If the application domain is loaded, I get the result, transpose first 1000 rows in 3 seconds. The most interesting thing here is the so-called context connection. Finally, take a look at the @rco parameter. By default, it is turned on, and it is not recommended to turn it off. I have opted to replaced my PIVOT statement with a series of CASE statements as Visakh recommended. There are many situations in which the results of a query look better when they are rotated. For example, if we execute T-SQL like in the listing below. This makes switching rows to columns easy. A Microsoft certified DBA on SQL Server 2000, and Microsoft certified System Engineer on Windows Server 2000, Darko has been working on various business applications as a .NET developer since 2002. There is an option with pivoting which includes aggregation and only moves the values from one column to column headings. / By Mohamed El-Qassas / Microsoft SQL Server / Convert Rows to columns using 'Pivot' in SQL Server when columns are string data type, convert the structure of the table data into a PIVOT, Pivot table without using Aggregiate function, Pivot with out aggregate, SQL Server 2014, SQL Server 2016, SQL Server 2017, The PIVOT Clause is Only for Aggregates Therefore, to use this solution as a whole, I included support for signing the assembly by using the asymmetric key. I like Phil Factor’s articles. Sending results is where SQLCLR magic ‘comes to light.’. In the solution, there are some interesting tests which are located in the Test.sql file. The properties of each database are listed vertically instead of horizontally. Recently, I came across a description of a transformation operation using SQL Server CLR – the goal is to convert, or transpose, columns into rows and rows into columns. In order to get the same result as in Phil’s example, you must call the MATRIX.Transposing stored procedure as shown in the listing bellow. That is not what T-SQL is designed for. I tested the solution on all SQL Server versions, starting with SQL 2005 until SQL 2017. The possible transformations include rotation, e.g., switching rows with columns. Notice the result of the second query is equal to the result of the first query. Help is available at any point by executing. But in this place, you have to ask yourself why you need a table of thousands of columns?

Therefore, the first execution of your SQLCRL function is always much slower than the next execution. The column that has the values defining the new columns 2. When a dataset is formed, then it is easy to perform many types of transformations. To run Phil’s solution, you must be running at least SQL Server 2016 version and make sure that the database is in 130 compatibility mode. oilConsumption ([2005], [2006], [2007], [2008], [2009], [2010], [2011], [2012]. This can be accomplished by: The solution proposed in this tip explores two SQL Server commands that can help us achieve the expected results. Get the latest news and training with the monthly Redgate UpdateSign up, 'D:\VS2017_PROJECTS\TransposingMatrix\TransposingMatrix\' with your path, --!Replace password with more appropriate for your situation.!!!!!!!!!!!!!!!!!!!!!! Wow! In the article, I showed you how to use SQLCLR to accomplish this task. You can see the whole script in the listing below. In this article, I will show you how to accomplish this task by introducing a SQLCLR stored procedure MATRIX.Transposing that does all the magic with rotation. The solution uses SQL Server Database Project as the template. In short, T-SQL is not suitable enough to transpose the query result. I have a SQL report which pulls a list of orders. So, in my opinion, there is no easy way to do it. The post-deployment script is located in the PostDeployment.sql file. After transposing (executing the query from the listing above ), you will get the results as shown in the image below. However, you will get the result, as shown in the image below. As you probably expect SendResultEnd marks the end of a result set and returns the SqlPipe instance to the initial state. Prerequisites Install MS SQL Server 2012. The solution works fine on SQL Server 2005+. If you try to transpose a table with more than 1000 rows, a warning is displayed in the message window, and you get first 1000 rows transposed. Apply ROW_NUMBER() function over this column. This involves turning columns into rows by, in effect, transposing the two coordinates. There is a maximum number of columns that you can have per SQL Server table; it could be up to 30000 columns. The listing below shows how to get the dataset. Execute the T-SQL displayed in the listing below. It means building a SQLCLR project. (5332, 5504, 5780, 6057, 6054, 6384, 6624, 6782, 7035, 7190, 7083). At first, you must enable CLR if not already enabled. The result is shown in the image below. You can see the post-deployment script in the listing below. The application domain is a lightweight process used to enforce isolation between running .NET code within the same SQLOS process. (20213, 20426, 20166, 20086, 19276, 19223, 19075, 18605, 18372, 18266, 18380). In the solution, getting the data is accomplished in DataAccess.cs. It could be a permanent or temporary table name. Also, what we should do with our results? It also allows performing aggregations, wherever required, for column values that are expected in … The filter is applied successfully. It means that you can use the solution starting with SQL Server 2005! The code uses classic ADO.NET techniques to get an object of type Dataset. “Write a SQL query to transpose these rows into columns.” Let’s understand the concept using the below table ,TblDeparmentEmployee. To answer this question let’s take a look at the image below. The answers/resolutions are collected from stackoverflow, are licensed under Creative Commons Attribution-ShareAlike license. The first column is named Key, and the others are Value, Value1, and so on. To explain the rest of the parameters, let us take the Phil example. In this article. The post-deployment script transfers the resulting stored procedure from the default DBO schema to newly created MATRIX schema and creates some defaults.
