How to insert data into table using stored procedures in postgresql

Question

CREATE TABLE app_for_leave
(
  sno integer NOT NULL,
  eid integer,
  ename varchar(20),
  sd date,
  ed date,
  sid integer,
  status boolean DEFAULT false,
  CONST         


        

Answer 1

Starting from PostgreSQL 11 you could create stored procedures and invoke them using CALL:

CREATE PROCEDURE MyInsert(_sno integer, _eid integer, _sd date,
                          _ed date, _sid integer, _status boolean)
LANGUAGE SQL
AS $$
    INSERT INTO app_for_leave(sno, eid, sd, ed, sid, status)
    VALUES(_sno, _eid, _sd, _ed, _sid, _status);   
$$;

CALL MyInsert(1,101,'2013-04-04','2013-04-04',2,'f' );

Plus it allows to handle transaction

SQL Stored Procedures

PostgreSQL 11 introduces SQL stored procedures that allow users to use embedded transactions (i.e. BEGIN, COMMIT/ROLLBACK) within a procedure. Procedures can be created using the CREATE PROCEDURE command and executed using the CALL command.
