Thanks, Jay “Write a SQL query to transpose these rows into columns.” Let’s understand the concept using the below table ,TblDeparmentEmployee. It is worth exploring and using in solving practical problems. In the script, the table is filtered passing two parameters and the WHERE clause. However, you will get the result, as shown in the image below. In the solution, there are two kinds of transformations which are determined by the parameter @keyValueOption. To transpose table ‘Person.Person’ which has about 20K records, you will get the warning like in the image below. Custom header(s), column names are separated by a comma. 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. 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. (6576, 6711, 6935, 7440, 7855, 8201, 8455, 8770, 9011, 9353, 9570). in our case column [countryName] is containing same value so data will be partitioned by this column- see the imag… If you specify @keyValueOption to 1 and submit @ColumnMapping as NULL, the result is shown in the image below. A SQL Server table is a slightly different structure, where rows and columns are not equivalent and interchangeable. In the solution, there are several T-SQL scripts. As you probably expect SendResultEnd marks the end of a result set and returns the SqlPipe instance to the initial state. There is an option with pivoting which includes aggregation and only moves the values from one column to column headings. When you transpose the original data and produce another table, the code must send the results. You are probably asking yourself if the solution limited to newest SQL Server version? SSMS has powerful capabilities to copy the result and paste, for example, into an Excel file. 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. Yes, the @Query parameter is the query whose results we would like to transpose. Wow! I need to convert this report into one which has a single row for each order. The solution works fine on SQL Server 2005+. When a user asks for some functionality located in your assembly the first time, an application domain is created. To answer this question let’s take a look at the image below. (NOTE: I am using the words transpose and rotation interchangeably as synonyms throughout the article.). This class cannot be inherited. The column on which rotation will take place after running the new code is outlined with red. Oracle Database 11g introduced the pivot operator. 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. Therefore, to use this solution as a whole, I included support for signing the assembly by using the asymmetric key. To explain the rest of the parameters, let us take the Phil example. It seems that SSMS is a little bit confused when has to display SQLCLR stored procedure parameters. An application domain is a construct in the Microsoft .NET Framework common language runtime (CLR) that is the unit of isolation for an application. In this spot, I have to make a small digression and describe the term of an application domain. The IN clause also allows you to specify an alias for each pivot value, making it easy to generate more meaningful column names. Prerequisites Install MS SQL Server 2012. What to show in the new columnsThe value in the new columns must be an aggregate. In my opinion, it is a bug in SSMS. SQLCLR uses application domains to isolate execution of .NET code on a per database and per assembly owner basis. Transposing data does not involve aggregations. To do this, execute the T-SQL script in the listing below. That is not what T-SQL is designed for. Step 1: Create the test table. SQLÂ 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. I tested the solution on all SQL Server versions, starting with SQL 2005 until SQL 2017. If you set @keyValueOption to 0, @columnMapping is ignored, and the result will look like the image below.
