Re: How to get minutes????

The CONVERT function is used to convert characters from one character set to another. For example from latin to ASCII. I don't think that is what you are looking for.

In order to use the time component of any date, you must isolate that information. Use the TO_CHAR( ) function to do this. The syntax for TO_CHAR is as follows:

TO_CHAR( date, format )

Example: TO_CHAR( log_end_date, 'HH24MISS' )

Have you tried the following:

TO_NUMBER(TO_CHAR(log_end_date, 'HH24MISS')) - TO_NUMBER(TO_CHAR(log_start_date, 'HH24MISS'))

The above statement assumes the start date and end date are always on the same day. I'll let you figure out the necessary logic if they are not.

Oracle9i now has a TIMESTAMP datatype that may be more applicable in your case. You might want to check it out.

Hope that helps...
