I have the following query,

SELECT * FROM LOGS 
WHERE CHECK_IN BETWEEN CONVERT(datetime,'2013-10-17') AND CONVERT(datetime,'2013-10-18')

this query not returning any result, but the following query return the result,

SELECT * FROM LOGS WHERE CHECK_IN >= CONVERT(datetime,'2013-10-17')

why the first query not returning any result? If I did any mistake pls correct me.

Do you have times associated with your dates? BETWEEN is inclusive, but when you convert 2013-10-18 to a date it becomes 2013-10-18 00:00:000.00. Anything that is logged after the first second of the 18th will not shown using BETWEEN, unless you include a time value.

Try:

SELECT * FROM LOGS WHERE CHECK_IN BETWEEN CONVERT(datetime,'2013-10-17') AND CONVERT(datetime,'2013-10-18 23:59:59:999')

if you want to search the entire day of the 18th.

SQL DATETIME fields have milliseconds. So I added 999 to the field.
