Hi...I'm sorry if i posted again this issue..I just really want a help to resolved my problem...I just want to know what logic..what syntax should i need to used to satisfied the conditions that I needed so that the rendered will have a correct output. Because in rendered will depend the salary of an employee :(Honestly, I always think what syntax should i need but still I really don't know how to do it..I hope somebody will understand my situation and help me to solve it.Thank you so much...EMP_NO-------DATE_DTR-------LOGIN------------------------LOGOUT---------------RENDERED----------This shift is 21:35:00 - 05:35:0000300395-----2011-12-01-----2011-12-01 21:30:00----------2011-12-02 05:45:00--08:00:00//rendered should be 08:00:00 because his login <= 21:35:00 and his logout is >= 05:35:00But i have a lot of shift:21:35:00 - 05:35:0005:35:00 - 13:35:0013:35:00 - 21:35:0007:00:00 - 16:00:0008:00:00 - 16:00:0008:00:00 - 17:00:0008:00:00 - 18:00:00when I used this code:

I got a problem to get the rendered for 21:35:00 - 05:35:00 shift if the login <= 21:35:00 logout >= 05:35:00

when time_to_sec(time(LOGIN)) <= time_to_sec('21:35:00') AND time_to_sec(time(LOGOUT)) >= time_to_sec('05:35:00')then sec_to_time(time_to_sec('08:00:00'))

when I used it all shifts will affected..Because I think it only check in time.I have a lot of conditions needed per shift.Like this://if the employee is early login from his shift and late logout from his shift the rendered will be 08:00:00//if the employee is late to login the 08:00:00 will minus//if the employee is undertime or early to logout 08:00:00 will minus//if the employee is late to login and early to logout the the sum of late login and early logout will minus in 08:00:00IF LOGIN <= 'SHIFT IN' AND LOGOUT >= 'SHIFT OUT' THEN RENDERED WILL 08:00:00IF LOGIN <= 'SHIFT IN' AND LOGOUT < 'SHIFT OUT' THEN RENDERED WILL 08:00:00 - (LOGOUT - SHIFT OUT)IF LOGIN > 'SHIFT IN' AND LOGOUT >= 'SHIFT OUT' THEN RENDERED WILL 08:00:00 - (LOGIN - SHIFT IN)IF LOGIN >= 'SHIFT IN' AND LOGOUT <= 'SHIFT OUT'THEN RENDERED WILL 08:00:00 + (LOGOUT - SHIFT) 08:00:00 - (LOGIN - SHIFT) Thank you so much...

If you want to do all of that in SQL, I suggest you use a stored procedure. Otherwise, that logic should go in PHP. If you want to cram all of that logic into a single massive SQL statement then you'll make it pretty difficult for someone to make changes to that at a later time, it's not very easy to understand.

I think you should create temporary tables and process the temporary tables one at a time. For example you might copy all of the entries from the master table which meet a certain criteria -- such as having login times between 05:35:01 and 07:00:00 on December 10 and create a temporary table and then process that table. Then drop the temporary table and create it again with the next group who logged in between 07:00:01 and 08:00:00 on December 10 and then process that table. Etc...
