Description
Get the value of primary key fields of current record in a class temp-table.
PreCondition
This method does not do any read operations. A record must be available in the default buffer of the class temp-table.
Parameters
| ihBuffer | input | handle | handle to class temp-table buffer |
| ocPKValue | output | character | chr(2) seperated list of field values |
| oiReturnStatus | output | integer | Return status of the method. |
