Datetime in where clause

Question

How can I select 12/20/2008 in where clause of sql?

The server is SQL server 2005.

select * from tblErrorLog
where errorDate = \'12/20/2         


        

Answer 1

Assuming we're talking SQL Server DateTime

Note: BETWEEN includes both ends of the range, so technically this pattern will be wrong:

errorDate BETWEEN '12/20/2008' AND '12/21/2008'

My preferred method for a time range like that is:

'20081220' <= errorDate AND errordate < '20081221'

Works with common indexes (range scan, SARGable, functionless) and correctly clips off midnight of the next day, without relying on SQL Server's time granularity (e.g. 23:59:59.997)
