Example: Using Execute SQL Task

Here's a brief example of how you might use the Execute SQL Task to set a variable before other tasks run:


-- Inside the Execute SQL Task configuration:
-- Connection: YourDatabaseConnection
-- SQLStatement:
DECLARE @MaxLoadDate DATETIME;
SELECT @MaxLoadDate = MAX(LoadDate) FROM dbo.DimDate;
YourPackageVariable = @MaxLoadDate;
