Hello, I have a table with OWN_ID and OWN_Email -

3ace7cf80edd    |   [email protected]
3acf6af33ff7    |   [email protected]
3acda2524e00    |   [email protected]
3ad75583c9a7    |   [email protected]
3ad74b018999    |   [email protected]

etc.

the problem is that it should contain only a single ID per Email, also I need to replace all OWN_ID values in another table by highest OWN_ID value of the OWN_Email
