Must declare the scalar variable "%.*ls". |
Explanation
This error occurs when a variable is used in a SQL script without first declaring the variable. The following example returns error 137 for both the SET and SELECT statements because @mycol is not declared.
SET @mycol = 'ContactName';
SELECT @mycol;
One of the more complicated causes of this error includes the use of a variable that is declared outside the EXECUTE statement. For example, the variable @mycol specified in the SELECT statement is local to the SELECT statement; thus it is outside the EXECUTE statement.
USE AdventureWorks2012;
GO
DECLARE @mycol nvarchar(20);
SET @mycol = 'Name';
EXECUTE ('SELECT @mycol FROM Production.Product;');
User Action
Verify that any variables used in a SQL script are declared before being used elsewhere in the script.
Rewrite the script so that it does not reference variables in the EXECUTE statement that are declared outside of it. For example:
USE AdventureWorks2012;
GO
DECLARE @mycol nvarchar(20) ;
SET @mycol = 'Name';
EXECUTE ('SELECT ' + @mycol + ' FROM Production.Product';) ;
