Description
Read field values of a specific record in one of the class temp-tables.
(Used from referential integrity)
Parameters
| icTableName | input | character | class temp-table name |
| icQuery | input | character | read statement |
| icFieldNames | input | character | Comma seperated list of table field names |
| ilConvertToDisplayFormat | input | logical | Only relevant for decimal or date fields |
| ocFieldValues | output | character | chr(3) seperated list of the field values (if a record is found) |
| oiReturnStatus | output | integer | Return status of the method. |
