Question

I am having problems with a Stored Procedure I am writing.

I am gathering data from a number of tables, most of which hold a date value, but one holds just a month(int)

I declare the following Parameters at the beginning of my SP.

@FromDate DateTime,
@ToDate DateTime

This works fine for most of my tables, but for the table where I am just requiring the Month from the @FromDate, I run into the following error:

“Failed to convert parameter value form a DateTime to a Int32.”

Here is my Select statement for the Problem Table:

SELECT Branch, Discount 
    FROM MonthlyPromotions
    WHERE (Month = DATEPART(mm,@FromDate))

Also, in the MonthlyPromotions Table the Month Field is an Int.

Can anyone help on this ASAP??

Thankyou

To troubleshoot your problem, can you do a

PRINT CAST(CAST(DATEPART(mm, @FromDate) AS INT) AS VARCHAR(50))
RETURN

At the beginning of your SP?
If that doesn’t give an error, you can proceed to:

SELECT Branch, Discount 
    FROM MonthlyPromotions
    WHERE Month = CAST(DATEPART(mm,@FromDate) AS INT)
