skunk.net.message

package skunk.net.message

Definitions of Postgres messages, with binary encoders and decoders. Doc for this package isn't very good yet, but the message formats are well documented at the linked pages below. It's a straightforward mapping.

It's probably useful to point out that Codec, Encoder, and Decoder in this package are from scodec. They're '''not''' the data types of the same name and same general design that are defined above in the skunk package. I realize this is confusing, but it shouldn't be a concern for anyone other than people working on the wire protocol, which never changes (heh-heh) so it shouldn't be a big deal.

case class CommandComplete(completion: Completion) extends BackendMessage

Command-completed response. The command tag is usually a single word that identifies which SQL command was completed.

Command-completed response. The command tag is usually a single word that identifies which SQL command was completed.

  • For an INSERT command, the tag is INSERT <oid> <rows>, where rows is the number of rows inserted. oid is the object ID of the inserted row if rows is 1 and the target table has OIDs; otherwise oid is 0.
  • For a DELETE command, the tag is DELETE rows where rows is the number of rows deleted.
  • For an UPDATE command, the tag is UPDATE rows where rows is the number of rows updated.
  • For a SELECT or CREATE TABLE AS command, the tag is SELECT rows where rows is the number of rows retrieved.
  • For a MOVE command, the tag is MOVE rows where rows is the number of rows the cursor's position has been changed by.
  • For a FETCH command, the tag is FETCH rows where rows is the number of rows that have been retrieved from the cursor.
  • For a COPY command, the tag is COPY rows where rows is the number of rows copied. (Note: the row count appears only in PostgreSQL 8.2 and later.)
