Question

I’m migratting a MS Access system into a mySQL system with PHP PDO. Everything’s ok until PHP stop readding some records on an Access table. This table has an ID field that’s a Long Integer datatype. I don’t know why but the ID starts from 0 to 16949 then jumps to 36573745 and ends at 36581986. These higher numbers the PDO doesn’t read, I can’t figure out why.

Anyway to workaround this, I’m trying to UPDATE these higher numbers to continue the normal sequence of the lower ID’s. But Access can’t understand my query and I don’t know how to make it run.

This is the query

UPDATE Validador_Manut SET ID = (
    SELECT (Max(ID) + 1) FROM Validador_Manut WHERE ID < 100000
) WHERE ID > 100000

It’s shows me this error Uperation must use an updatable query.

Answer 1

If you just want to lower the IDs > 100000 to consecutive numbers after 16949
then why don’t you try simply this?

UPDATE Validador_Manut SET [ID] = [ID]-36556795 WHERE ID > 100000 

36573745 – 36556795 = 16950
