Hi pals,
I have a module in my PHP application that creates and id (string + the auto_increment field). I read the last auto_increment value from the table, then in my code I use it as the base to create a second id (the auto_increment field + string). This happens for as many hardware the user has selected to send for repairment but, What if another user also is sending hardware for repairment? His process will also read the same auto_increment value from the table, will use it to create the second id field in my code, so, probably I will have ids like: Last auto_increment value = 1 User A VSA002 VSA003 User B TUX002 TUX003 I have a constraint: The ID part (from string + the auto_increment field) should be continuos! I can not have two IDs with the same auto_increment value in it!! Is there a way to use transactios in MySQL?? Or maybe using a global variable accesed by all the processes running in the server? Or actually creating the auto_increment fields by inserting as many rows needed, but what if the user cancels the operatuion? Or another different approach to solve this problem?
