Question

I have the following code:

DECLARE @monthPassed VARCHAR(MAX)
SET @monthPassed = '2010'

DECLARE @yearPassed VARCHAR(MAX)
SET @yearPassed = '10'

DECLARE @TempDate DATETIME
SET @TempDate = CAST(@monthPassed + '/' + '1' + '/' + @yearPassed AS DATETIME)

DECLARE @TestDate DATETIME
SET @TestDate = DATEADD(MONTH, 1, @TempDate)

This makes @TestDate 11-02-10. How would I always make this return the first of the month instead?

Answer 1

Might have something to do with @monthPassed and @yearPassed being inverted. Switching them, on my end, resolved the problem.

DECLARE @monthPassed VARCHAR(MAX)
SET @monthPassed = '10'

DECLARE @yearPassed VARCHAR(MAX)
SET @yearPassed = '2010'

DECLARE @TempDate DATETIME
SET @TempDate = CAST(@monthPassed + '/' + '1' + '/' + @yearPassed AS DATETIME)

DECLARE @TestDate DATETIME
SET @TestDate = DATEADD(MONTH, 1, @TempDate)

SELECT @TestDate;

Results in:

+-------------------------+
|    (no column name)     |
+-------------------------+
| 2010-11-01 00:00:00.000 |
