Hi i have a select statement which if the parameter @SubCatID = 0

then i need this where clause

WHERE St_Cat_ID = @SubCatID AND

@StockCode LIKE '%' + @Code + '%'

else i need this where clause

WHERE St_Cat_ID = @SubCatID AND @StockCode LIKE '%' + @Code + '%'

how do i go about doing this

I'm confused. Both WHERE clauses look the same to me...?

If St_Cat_ID's are not equal to 0 then you can do something like this:

WHERE
	(@SubCatID = 0 OR St_Cat_ID = @SubCatID)
	AND StockCode LIKE '%' + @Code + '%'
