Question

If it’s greater than 10 set the variable to -1 and select that variable output.
If less than 10 select the variable as the output.

DECLARE @i INT
SET @i = 10 
SELECT @i = (@i * 10)

Thank You,

Answer 1

you cannot combine a select statement that assigns a value to a variable with an expression that returns data… So you need two statements…

Declare @I Integer = 4

Select @I = Case When @I > 10 Then -1 Else @I End
Select @I
