Question

There is a table which had records but these records were deleted. There is a primary key which is incremented automatically on the database table.

Is there a way to know , before inserting a new row in the table , the next value of this primary key ? If it is not possible is there a way to get the immediately the value of the generated primary key after inserting a row ?

Answer 1

You could insert a row and then look at last_insert_id:

insert into ....;
select last_insert_id();

That would give you the auto_increment value that was used for the INSERT.

You can also try looking at the show table status like 'your_table_name' output, there will be an Auto_increment value that should tell you the next one that will be used.
