Question

I want to make sure that when I execute my query, that it will fit only one time

INSERT INTO SERVICEPAYANT ( TYPE_FLUX, DELAI ) VALUES (160,'9999');
INSERT INTO SERVICEPAYANT ( TYPE_FLUX, DELAI ) VALUES (161,'9999');
INSERT INTO SERVICEPAYANT ( TYPE_FLUX, DELAI ) VALUES (162,'9999');
INSERT INTO SERVICEPAYANT ( TYPE_FLUX, DELAI ) VALUES (163,'9999');

Answer 1

INSERT INTO SERVICEPAYANT 
            (TYPE_FLUX, 
             DELAI) 
SELECT 161, 
       '9999' 
FROM   dual  
WHERE  NOT EXISTS (SELECT 1 
                   FROM   SERVICEPAYANT 
                   WHERE  TYPE_FLUX = 161 
                          AND DELAI = '9999')
