Error SQL: ORA-04091: table LIBRERIA.LIBRO is mutating, trigger/function may not see it
ORA-06512: at "LIBRERIA.AI_LIBRO", line 9
ORA-04088: error during execution of trigger 'LIBRERIA.AI_LIBRO'
04091. 00000 - "table %s.%s is mutating, trigger/function may not see it"
*Cause: A trigger (or a user defined plsql function that is referenced in
this statement) attempted to look at (or modify) a table that was
in the middle of being modified by the statement which fired it.
*Action: Rewrite the trigger (or function) so it does not read that table.
