Database / SQL
Hi, I am Vinay, My question is how to create Empid (ex:Empid: TCS-456) and to save in Mysql BD, if next, I enter other then it should be incremented like Empid: TCS-456/7/8/9..etc.
Hi there, my suggestion would be using a DB sequence (or a separate table for the sequence in MYSQL DB) to generate a unique number (for example,456) and have a Database trigger (before-insert) to prefix "TCS-". This way we will make sure a unique id is generated. This solution completely relies on database objects.
if we want to achieve this using Java/hibernate, we can generate a unique number and prefix "TCS-".
