PLS-00425

Error: PLS-00425: in SQL, function argument and return types must be SQL type

Causa: When a stored function was called from a SQL statement, parameters of the wrong type were passed. To be callable from SQL statements, a stored function must meet several requirements, one of which is that its arguments have SQL datatypes such as CHAR, DATE, or NUMBER. None of the arguments can have non-SQL types such as BOOLEAN, TABLE, or RECORD.

Acción: Make sure all the arguments in the function call have SQL datatypes.
