Hi

I am going to set up a foreign key from a table under schema A to the other table under schema B.
I am getting Oracle Error
Ora-00942, Table or View does not exist.
But this is for sure that the tables highly exist in shemas A and B.
Please help me out.

Thanks a lot in advance.

Regards,
Suranjita

You have to grant access to the other schema so that it can see the table.

Additionally, this privilege should be REFERENCES in order to establish referential integrity constraint. Furthermore, columns must match in number and datatype. Also, master table must have a primary or unique key constraint on this (those) column(s).
