Oracle : Ошибка ORA-30352

"inconsistent numeric precision or string length"
*Cause: 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.

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