Cannot Update

[violette]

I'm having problem to update the data into mysql database. for insert new data, it works nicely but if i want to update the existing data, it will hang my pc. even if i debug line by line, it shows like infinite loop. which part has gone wrong? i'm totally no idea.

I believe that you've messed up your IFs.
You've got 2 IF recordExistCom = False Then and the second of them ends just before the loop.
The Else you've got between insert and update will only work for the inner if, and you'll never update.

PS: It would make it easier to control the IFs if you kept changed the

IF tradeReceivable = NULL Then
 tradeReceivable = 0
 End IF

to

IF tradeReceivable = NULL Then tradeReceivable = 0

and similar for all the field values you're doing this for.

For sheet to work, I think you must have loop in lopp

for 1 to n worksheet
while cell empty
end while
end for

and for duplicate checking ur codes may hang due to deadlock, you can follow the link given here

thanks guys. :) i've found my mistakes. missing commas in the Update sql. that's why it's not work. i've simplified my code according to adam_k has suggested as well. thanks a lot! :)
