Question

When I try to print a line with int and nvarchar in a single line I get an error. Here’s the entirety of my code.

DECLARE @COUNT INT, @CONST INT
SET @COUNT = 0
SET @CONST = 12

WHILE(@COUNT<12)
BEGIN
    SET @COUNT = @COUNT + 1
    PRINT @COUNT + N' times ' + @CONST + N' is ' + @COUNT*@CONST
END

The error I get is:

Msg 245, Level 16, State 1, Line 8
Conversion failed when converting the nvarchar value ‘ times ‘ to data type int.

I can print ‘int’ a nvarchar just find on their own, but when I combine them I get this error. Am I improperly combining them?

I’m using Microsoft SQL Management Studio

You should CAST your variables as nvarchar first:

DECLARE @COUNT INT, @CONST INT
SET @COUNT = 0
SET @CONST = 12

WHILE(@COUNT<12)
BEGIN
    SET @COUNT = @COUNT + 1
    PRINT CAST(@COUNT as nvarchar) + N' times ' + CAST(@CONST as nvarchar) + N' is ' + CAST(@COUNT*@CONST as nvarchar)
END
