EXEC sp_executesql with multiple parameters

Here is a simple example:

EXEC sp_executesql @sql, N'@p1 INT, @p2 INT, @p3 INT', @p1, @p2, @p3;

Your call will be something like this

EXEC sp_executesql @statement, N'@LabID int, @BeginDate date, @EndDate date, @RequestTypeID varchar', @LabID, @BeginDate, @EndDate, @RequestTypeID

This also works....sometimes you may want to construct the definition of the parameters outside of the actual EXEC call.

DECLARE @Parmdef nvarchar (500)
DECLARE @SQL nvarchar (max)
DECLARE @xTxt1  nvarchar (100) = 'test1'
DECLARE @xTxt2  nvarchar (500) = 'test2' 
SET @parmdef = '@text1 nvarchar (100), @text2 nvarchar (500)'
SET @SQL = 'PRINT @text1 + '' '' + @text2'
EXEC sp_executeSQL @SQL, @Parmdef, @xTxt1, @xTxt2
