CommandComplete

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.)
