Suppose, now we would also like to include the marks for the column “History” in this pivot table, the only thing that you should do is to add the name of the column in the second parameter and execute the stored procedure. Creating a sample data Sytech Solutions. Now let us try to break the above script and understand how it works. In his leisure, he likes to keep his skills sharp by writing articles on his blog and other forums. From . PIVOT rotates a table-valued expression by turning the unique values from one column in the expression into multiple columns in the output, and performs aggregations where they are required on any remaining column values that are wanted in the final output. What is the difference between Clustered and Non-Clustered Indexes in SQL Server? Pivot tables are a piece of summarized information that is generated from a large underlying dataset. 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. --Get distinct values of the PIVOT Column SELECT @ColumnName= ISNULL(@ColumnName + ',','') + QUOTENAME([hour]) FROM (SELECT DISTINCT [hour] FROM #temp) AS Courses --Prepare the PIVOT query using the dynamic SET @DynamicPivotQuery = N'SELECT EmpId, ' + @ColumnName + ' FROM #temp PIVOT… His main areas of interest are SQL Server, SSIS, and SSAS. If you want to filter rows in your final pivot table, you can add the WHERE clause in your SET statement. In the above illustration, the rows are taken from the Student column, the columns are taken from the Subject, and the values are created by aggregating the Marks column. 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. There are several ways to transpose a dataset from rows to columns and columns to rows. Let us replicate the first scenario where we visualized all the three subjects – Mathematics, Science and Geography in the pivot table in SQL. In order to generate such a query dynamically, we can look to sys.columns to derive the column names. The Pivot is used to transpose the rows into columns .This is used in reporting and creating interactive reports. The table on the left is the actual table that contains the original records. Then we use while loop to create dynamic column name and store it into local variable @DynamicColumnName. Another scenario would be like if the requirements change and now, we need to pivot students instead of the subjects, even in such a case, we would need to modify the entire query. Let us try to select the data from the table that we just created as below. We will just modify the values in both the parameters such that the first parameter indicates the column “Student” and the second parameter will contain the list of students that you want along with the columns. The only limitation in this process is that we need to provide hardcoded values for the columns that we need to select from the pivot table. In this article, we will show how to convert rows to columns using Dynamic Pivot in SQL Server. The Oracle 11g has a clause which helps to write SQL query to turn rows to the columns and vice-versa. Let us go ahead and insert a few records into the table for a different subject – “History“.
