You're in the
sql server programming
group:Stored Procedures and the GetTime() function
sql server programming:
I want to write a conditional statement in which a timestamp in a
database is compared to the current time. Example: If timestamp value is [quoted text, click to view] >= (current time - 1 hour) then return 0, else return 1. The purpose of this is to verify that data has been imported in to the table within the last hour. I figured the GetTime() function would provide me with the current time but I'm not sure how to set it up so that it evaluates the current time - 1 hour. Any help would be greatly appreciated. Thanks, -- Grant Smith A+, Net+, MCP x 2 Quality Production Liaison Hewlett Packard Company Database Administrator

Since there is no GetTime() function in SQL Server, this is a little confusing. In which environment are you working in and want to write you conditional statement? -- Erland Sommarskog, SQL Server MVP, esquel@sommarskog.se Books Online for SQL Server 2005 at http://www.microsoft.com/technet/prodtechnol/sql/2005/downloads/books.mspx Books Online for SQL Server 2000 at

I actually had to code it like this to get the syntax check to recognize it: CREATE PROCEDURE [dbo].[gs_VerifyImportLite] @timeCheck datetime AS SET @timeCheck = DateAdd(hour, -1, GetDate()) if exists (SELECT * FROM IMPORT_LITE WHERE Upload_date >= @timeCheck) return 0 else return 1 According to what I've been reading, you have to declare variables before the AS section. Thanks again for your help. I just hope it works... LOL -- Grant Smith A+, Net+, MCP x 2 Quality Production Liaison Hewlett Packard Company Database Administrator

So I wrote the following stored procedure and it runs just fine but I can't seem to get the job to fail on a return of 1. Any ideas? CREATE PROCEDURE [dbo].[gs_VerifyImportLite] AS DECLARE @timeCheck datetime SET @timeCheck = DateAdd(hour, -1, GetDate()) if exists (SELECT * FROM IMPORT_LITE WHERE Upload_date >= @timeCheck) return 0 else return 1 GO Thanks, -- Grant Smith A+, Net+, MCP x 2 Quality Production Liaison Hewlett Packard Company Database Administrator

Did you explain what context the program runs in? Without knowledge of that, it's difficult to have ideas. :-) But if you want an error, using RAISERROR may be a better option. -- Erland Sommarskog, SQL Server MVP, esquel@sommarskog.se Books Online for SQL Server 2005 at http://www.microsoft.com/technet/prodtechnol/sql/2005/downloads/books.mspx Books Online for SQL Server 2000 at

I changed the SP to use RAISERROR. I haven't figured out if it works yet or not because there hasn't been a situation where I could force a fail...
