double entry on button

Hello

There can be several possibilities to get double entries in the database. please check the below points.

• Button Click Event: add multiple click prevent code.
• Add Primary key constraint: to prevent duplicate entries in the database you can add primary or unique key constraints.
• Check duplicate code for insert data in the database from different places. If this is the case, you should check if an entry already exists then only update the existing otherwise add a new entry.

Thanks
