I'm converting SQL from Teradata to SQL Server in Teradata, they have the format SELECT col1, col2 FROM table1 INTO @variable1, @variable2 In SQL Server, I found SET @variable1 = ( SELECT col1 FROM table1 ); That only allows a single column/variable per statement. How to assign 2 or more variables using a single SELECT statement? SELECT @variable1 = col1, @variable2 = col2 FROM table1 Svetlozar Angelov SELECT @var = col1, @var2 = col2 FROM Table Here is some interesting information about SET / SELECT SET is the ANSI standard for variable assignment, SELECT is not. SET can only assign one
