From: DavidC on 26 Aug 2010 18:09 I have the following DECLARE that works fine but I need to handle times when the day of a date is not = 1 and @Month passed is less than 10 so the date gets '0x' for month or day. Below is my current CAST. DECLARE @StartMoth date; SET @StartMonth = CAST(CAST(@Year as char(4)) + CAST(@Month as char(2)) + '01'); Thanks. -- David

Hi David, I think it would be easier if you had one parameter of datetime. A datetime (or date) could be converted directly to the format that you want with convert. With a single date(time) parameter you could do the following --- this just to make as if I had a parameter of datetime declare @myParameter datetime set @myParameter = getdate() --- end code for make as if I had a parameter select convert(varchar, @d, 112) MyDate the response is MyDate -------- 20100902 In this example I build a date from integers and then cast it with convert to get the format that you want. Note that I used varchars instead of chars as you did. declare @MyDay int = 5 declare @MyMonth int = 9 declare @MyYear int = 10 declare @MyDateStr varchar(10) declare @MyDate datetime set @MydateStr = cast(@MyYear as varchar(4)) + '/' + CAST(@MyMonth as varchar(2)) + '/' + CAST(@MyDay as varchar(2)) set @MyDate = CONVERT(datetime, @MydateStr, 11) select convert(varchar, @MyDate, 112) MyDate Mike http://www.homemadepride.com "DavidC" <dlchase(a)lifetimeinc.com> a écrit dans le message de news:3F00F204-619F-42AE-81AD-4EDBF4A50244(a)microsoft.com... >I have the following DECLARE that works fine but I need to handle times >when > the day of a date is not = 1 and @Month passed is less than 10 so the date > gets '0x' for month or day.
