I can't insert more than one row in the table

[Nuha]

 

Hi I created a table and inserted many rows in it. the problem is when I use insert to add one row, it deletes the previous one causing the table to have only one row.

I tried to add my code but it seemed they don't allow sql here.

Please help

The index column must have the AUTO_INCREMENT keyword to perform an auto-increment function.
