A syntax error occurred because an unqualified SQL enumerated value name was specified, but, because that value name is a member of more than one enumerated type, its type could not be resolved. For example, the enumerated value name YES belongs to more than one enumerated type, and so the result type of the expression YES = YES can not be resolved. A list of all of the enumerated types declared by the server can be found in the SQL catalog table SYSCAT.ENUMTYPES.
