I have a database with a date/time stamp called dtstatusdatum. I would like to extract statistics from the database...
based on this column. What should the select clause look like. I tried:
select count(*) from mytable where dtstatusdatum like '2002-07-29%'
but get no results to the query:
(0) rows affected.
Thanks for mentioning "(0) rows affected" which tells me you're probably working with Microsoft SQL/Server. There are several ways to approach your query, but here's a simple one:
select count(*) from mytable where convert(dtstatusdatum,char(10),120) = '2002-07-29'
See the Microsoft documentation for CAST and CONVERT. Style 120 is the yyyy-mm-dd hh:mm:ss format, and converting to char(10) truncates the time off the end. Thus you can do a straight equality comparison rather than using LIKE.
