I only need UPDATE no INSERT since new rows are forbidden. Right now I have no class for my members. I load my DataGridView in C# with the following code: BindingSource bsMember = new BindingSource (); bsMember.DataSource = DBMember.Get (); dgv.DataSource = bsMember; The DBMember.Get () returns a DataTable made with the above shown SQL code.

This SQL Server tutorial explains how to use the PIVOT clause in SQL Server (Transact-SQL) with syntax and examples. Description The SQL Server (Transact-SQL) PIVOT clause allows you to write a cross-tabulation. 2 Answers. You could just use UNION ALL to combine the two results, you would need to convert the roles from the top query from int to VARCHAR though: DECLARE @ID INT = 1; WITH Ans AS ( SELECT DISTINCT SessionID,ItemID_FK,Roles FROM tbl_Answers WHERE ID_FK = @ID ), PivotData AS ( SELECT items.ItemID_PK, items.ItemName, cntRoles = COUNT (ans
This basically represents changes in the value of the column you are pivoting on and is then included in the implicit group by the pivot is doing, which results in getting multiple values in the pivoted column, not just the max. So in the code below the "expertisenum" column is keeping the integrity of the expertise data.
Is it possible to do a PIVOT and select list from a table, instead of using single values? Like this (incorrect syntax error): SELECT * FROM ( SELECT RepID, MilestoneID, ResultID FROM RM ) AS src PIVOT ( MAX(ResultID) FOR MilestoneID IN (SELECT id FROM m) ) AS pvt This one compiles, but doesn't work for me:
This would be the query for that: select * from (select *, rank () over (partition by studid order by school) rank from student) r pivot (max (school) for rank in ( [1], [2], [3])) pv. note that max doesn't actually do anything. the query would return the same results if you replaced it with min. just the pivot syntax requires the use of an
Put the name of the student in the subquery FROM ( SELECT Student, Grades, Subject FROM Grade_Report )AS SourceTable. SELECT Student, [English], [Mathematics
However, what you've suggested seems to be equivalent to my original code in that still get nulls in the pivoted fields which result in the grand total column having nulls. To correct this the first line select statement should be SELECT var1, var2, var3, [1], [2], isnull ( [1],0) + isnull ( [2],0) AS Total.

These columns are grouping columns. For each expression tuple and aggregate_expression combination, PIVOT generates one column. The type is the type of aggregate_expression. If there is only one aggregate_expression the column is named using column_alias. Otherwise, it is named column_alias_agg_column_alias. The value in each cell is the result
