Re: [cx-oracle-users] Oracle Error :: ORA-01484 arrays can only be bound to PL/SQL statements

[Anthony T. <ant...@gm...>]

Oracle does not allow passing arrays to SQL statements, only PL/SQL
statements and this has been that way since as long as I have known
Oracle. The driver you were using before may have simply converted the
result to a string. cx_Oracle takes lists and converts them to PL/SQL
arrays -- which are not possible to be used in straight SQL
statements. So you will have to modify how you are using the driver.
In my opinion, converting lists to strings in some arbitrary fashion
is not the best way to handle such things!
