between and datetime column

Hi,



I have this select stmt:



SELECT * FROM table1 WHERE b BETWEEN a AND c



Here, a,b,c all the three columns are of type datetime. I want to retrieve records where time b is between start time a and end time c. The query complies successfully but at times the result displayed is incorrect..



Any solutions?

Thanks.

If you posted some details maybe someone can help. How is anyone to know what might make the results incorrect "at times" ?
