sql_mode=ORACLE: Implicit cursor FOR loop

    XMLWordPrintable

Details

    Description

      In addition to FOR loops on explicitly declared cursors (MDEV-10581), we'll implement FOR loops for implicit cursors.

      The SQL query for the implicit cursor is declared directly inside the FOR loop:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a INT, b INT);
      		 
      INSERT INTO t1 VALUES (10,20);
      		 
       
      		 
      DROP PROCEDURE IF EXISTS p1;
      		 
      DELIMITER /
      		 
      CREATE PROCEDURE p1 AS 
      BEGIN
      		 
        FOR rec IN (SELECT a, b FROM t1)
      		 
        LOOP
      		 
          SELECT rec.a, rec.b;
      		 
        END LOOP;
      		 
      END;
      		 
      /
      		 
      DELIMITER ;
      		 
      CALL p1();
