Release 10.1A: OpenEdge Development:
Progress 4GL Reference

RAW-TRANSFER statement

Copies a record wholesale from a source to a target.

Syntax

RAW-TRANSFER { [ BUFFER ] buffer TO [ FIELD ] raw-field | [ FIELD ] raw-field TO [ BUFFER ] buffer | [ BUFFER ] buffer TO [ BUFFER ] buffer } [ NO-ERROR ]

BUFFER

Specifies a parameter is a buffer.

buffer

A source or target database record.

Note: If the source buffer contains only a partial field list, RAW-TRANSFER fails.

FIELD

Specifies a parameter is a raw-field.

raw-field

A source or target data field of type RAW.

NO-ERROR

Suppresses Progress’s run-time error behavior and stores information on run-time errors, if any, in the ERROR-STATUS system handle.

Example

The following Progress 4GL example performs a RAW-TRANSFER of a newly created Customer record to the Record field of Replication-Log table:

TRIGGER PROCEDURE FOR REPLICATION-CREATE OF Customer. CREATE Replication-Log. ASSIGN Replication-Log.Taskid = DBTASKID(LDBNAME(BUFFER Replication-Log)) Replication-Log.Table = ’Customer’ Replication-Log.Action = ’CREATE’. RAW-TRANSFER Customer TO Replication-Log.Record.

For more information on database replication, see OpenEdge Data Management: Database Administration .

Notes

The RAW-TRANSFER statement has several variations:
The “buffer to raw-field” variation copies the entire record from the buffer to the raw field, prepending information on the source schema to the raw field.
The “raw-field to buffer” variation first checks that the source schema information prepended to the raw field matches the schema of the buffer. Then it creates a target record, if necessary. Finally it updates each key field in the new record using values from the raw field, which forces indexing to occur.
The “buffer to buffer” variation is the same as the “raw-field to buffer” variation, except that the source is a record in another buffer.
The RAW-TRANSFER statement respects database triggers.
You can marshal an OpenEdge database record so that it can be sent across sockets by using the RAW-TRANSFER statement to put the record into a RAW variable and then copying the RAW variable to a MEMPTR that is being written to a socket. Use the PUT-BYTES function to do this. You can unmarshal database records by using the GET-BYTES function and then RAW-TRANSFER.
At run time, the RAW-TRANSFER statement:
Checks that the signatures of the source data and the target data match.
Compares source and target code page ids, and (if they are present and different) translates the source’s character data, writing any warnings to the database log file and raising any error conditions.
Creates the target record, if none exists, and runs all appropriate CREATE triggers (unless the DISABLE TRIGGERS FOR LOAD option is active for the target).
Registers changes in key fields with the index manager by updating each key field in the target when it differs from the source.
Copies all data from the source record to the target record.
Executes ASSIGN triggers for any modified fields (unless the DISABLE TRIGGERS FOR LOAD option is active for the target).
When using the RAW-TRANSFER statement to copy a record that contains a BLOB or CLOB field, Progress skips the BLOB or CLOB field and stores the Unknown value (?) in the BLOB or CLOB field of the target record.
