Type

Syntax

Its value is TRUE if session reset is in progress and FALSE otherwise.Intended for use in ON DISCONNECT and ON CONNECT database triggers to detect an ALTER SESSION RESET.

ROW_COUNT

Number of affected rows of the last executed statement

Available in

PSQL

Type

INTEGER

Syntax
ROW_COUNT

The ROW_COUNT context variable contains the number of rows affected by the most recent DML statement (INSERT, UPDATE, DELETE, SELECT or FETCH) in the current PSQL module.

Behaviour with SELECT and FETCH

  • After a singleton SELECT, ROW_COUNT is 1 if a data row was retrieved and 0 otherwise.

  • In a FOR SELECT loop, ROW_COUNT is incremented with every iteration (starting at 0 before the first).

  • After a FETCH from a cursor, ROW_COUNT is 1 if a data row was retrieved and 0 otherwise.Fetching more records from the same cursor does not increment ROW_COUNT beyond 1.

Note

ROW_COUNT cannot be used to determine the number of rows affected by an EXECUTE STATEMENT or EXECUTE PROCEDURE command.
Example
update Figures set Number = 0 where id = :id;
if (row_count = 0) then
  insert into Figures (id, Number) values (:id, 0);
