ORA-08456

Error: ORA-08456: no sign in picture mask but SIGN clause in mask options

Causa: The picture mask parameter passed to a UTL_PG conversion routine contained no sign symbol ('S', '+', or '-'), but the mask options parameter contained a SIGN clause. A sign symbol is required in the picture mask parameter when the mask options parameter contains a SIGN clause.

Acción: Correct the picture mask parameter or the mask options parameter.
