Hello,

I am doing one application for filtering records according to filter entered by user.
I have one drop down list for filter types and one text box for filter string.
Filter conditions in drop down lists are :
?*, *?*, =, !=, >, >=, <, <=, etc

And i think end user will put following valid values in text box-
2013/04/04
April 2013
2013
07 Apr 2013
07 Apr
12:00
11:30 PM

My database table have following field-
uploaded_on (smalldatetime)

I have to write query such that whatever filter entered by user is, records should be filtered according to that.

Thanks.

I mean how do i write multiple cases to match the filter format user entered with format in database.
e.g. when input id Apr 2012, the output will contain all dates with month April, 2012
when input is 24, all dates with date 24 will be displayed, etc.

I can easily achieve this by writing multiple queries for each case, but i want to write those in single query.

Please, read about datetime and smalldatetime data types[^] for MS SQL Server.

Try to convert:

SQL

SELECT CONVERT(SMALLDATETIME, '12:00') AS MyDateTime

and see what happens.
