• Sql Server string to date conversion

  - by JosephStyons

  I want to convert a string like this: '10/15/2008 10:06:32 PM' into the equivalent DATETIME value in Sql Server. In Oracle, I would say this: TO_DATE('10/15/2008 10:06:32 PM','MM/DD/YYYY HH:MI:SS AM') This question implies that I must parse the string into one of the standard formats, and then convert using one of those codes. That seems ludicrous for such a mundane operation. Is there an easier way?

I'm new to the apache /php space so any keywords that i can search upon would be handy. Thanks.

  When my users enter a term like "word" I would like it be treated as a wildcard query "word*" so all terms beginning "word" are found. Is there a way to tell the QueryParser to automatically create wildcard queries or do I have to parse the query myself? This shouldn't be a problem for simple queries but it may become tricky for more complex queries.
