ORA-29256

Error: ORA-29256: Cursor contains both regular and array defines which is illegal

Causa: Both DEFINE_ARRAY and DEFINE_COLUMN have been called on this cursor. This is illegal. It is not possible for a cursor to both contain regular and array defines. The semantics of this setting are nonsensical. Array defines are used to move data from select queries into PL/SQL tables and regular defines to move data from select queries into PL/SQL variables.

Acción: Modify your PL/SQL program to only perform calls to one of the two functions depending on the situation at hand.
