[GENERAL] porting time calcs to PG
I'm trying to port an MS statement that's a bit involved with timestamps, and I don't see anything in the docs to lead me forward. It's basically a select statement, looking for records with a timestamp within a certain range, where that range is calculated with one of the fields. The WHERE clause that I use in SQL Server is: getdate() + ((2100 + 5 + (9*Points)) / 86400) = DueTime Where the numbers are actually parameters passed in to the function.

For the interval part, you can try interval '1 minute' * some number ---(end of broadcast)--- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
