ORA-30352

Error: ORA-30352: inconsistent numeric precision or string length

Causa: The SELECT expression was of a different numeric precision or string length than the corresponding container column. Therefore, query rewrite cannot guarantee results that are identical to the results obtained with the un-rewritten query.

Acción: Correct the precision or string length difference, specify the WITH REDUCED PRECISION option, or disable the REWRITE option on the materialized view.
