CREATE PROCEDURE WELL_LOGGIN(out P_well_schema varchar(60))
BEGIN
  DECLARE fin_c BOOLEAN DEFAULT 0;
  DECLARE VC_SCHEMA varchar(60);
  declare P_well_schema varchar(60);
  DECLARE VC_WELL_SCHEMA Varchar(30);
  DECLARE VC_REQUEST     Varchar(1000);
  DECLARE c CURSOR FOR SELECT DISTINCT table_schema  FROM information_schema.COLUMNS   WHERE table_name = 'WELL'AND column_name ='WELL_SCHEMA';
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET fin_c := 1;
  OPEN c;
  FETCH c INTO VC_SCHEMA;
  WHILE (NOT fin_c) DO
 
    IF VC_REQUEST IS NOT NULL THEN
      SET VC_REQUEST := concat(VC_REQUEST ,'UNION');
    END IF;
      SET VC_REQUEST = concat( VC_REQUEST ,' (select WELL_SCHEMA from ', VC_SCHEMA ,
                  '.WELL where Well_status = 3) ');
  END WHILE;
 SET @req := concat ('select into @PS_well_schema WELL_SCHEMA  from (',VC_REQUEST,')');
 
  PREPARE etat FROM @req;
  EXECUTE etat;
  DEALLOCATE PREPARE etat;
 
   set P_well_schema:=@PS_well_schema;
 
  END;
