Question

it is possible in one SQL statement to insert a record then take the autoincrement id, and update for the same record one specific column
with this autoincrement value.

Thanks in Advance.

Answer 1

Strictly speaking you can not do it in a single SQL statement (as others have already pointed out).

However, since you mention that you want to avoid making changes to legacy application let me clarify some options that might work for you.

• If you had a trigger on the table that would update the second column, then issuing single insert will give you what you want and you might not need to change anything in the application

• If possible, you could rename the table and in its place put a VIEW with the same name. With such simple view it might be transparent to your application (not sure if VIEW would remain updateable with your framework, but generally speaking it should)

• Finally, with mysqli library you are free to issue multiple SQL statements, so it will be a single call to the database – which might be enough for you, depending on how exactly you define ‘single statement’

None of the above will never be comparable to fixing the application in terms of maintainability for the guy who will inherit your code.
