Question

I have to insert many product value records into an Oracle table. I get all the data from an xls file, processing it with PHP and (for now) spitting out a long SQL statement. As each record is inserted, I want to check the Product IDs I got from the xls against the products already in the database, skipping the insert if the IDs don’t match a product. The statement I tried is the following:

INSERT ALL 
INTO PRODUCTOS_X_PLANES_CATEGORIA(PXG_ID, PXG_PRODUCTO, PXG_PLAN_CATEGORIA, PXG_VALOR)
    VALUES (NULL, 123456, 81, 10000)
INTO PRODUCTOS_X_PLANES_CATEGORIA(PXG_ID, PXG_PRODUCTO, PXG_PLAN_CATEGORIA, PXG_VALOR)
    VALUES (NULL, 7890, 76, 11000)
SELECT * FROM DUAL;

Which gets me an

[Err] ORA-02291: integrity constraint (OURDB.PXG_PRODUCTO_FKEY) violated - parent key not found

error message. I want to check that the PXG_PRODUCTO key exists before attempting the insert. I should check against the PRODUCTOS.PRO_ID field. I tried something like

INSERT ALL 
INTO PRODUCTOS_X_PLANES_CATEGORIA (PXG_ID, PXG_PRODUCTO, PXG_PLAN_CATEGORIA, PXG_VALOR) 
    VALUES (NULL, 123456, 81, 10000) 
    USING PRODUCTOS ON PXG_PRODUCTO = PRO_ID
INTO PRODUCTOS_X_PLANES_CATEGORIA (PXG_ID, PXG_PRODUCTO, PXG_PLAN_CATEGORIA, PXG_VALOR) 
    VALUES (NULL, 7890, 76, 11000) 
    USING PRODUCTOS ON PXG_PRODUCTO = PRO_ID
SELECT * FROM DUAL;

getting only a

[Err] ORA-00928: missing SELECT keyword

message. What’s the correct syntax? Or, if I’m completely wrong, what should I be doing instead?

EDIT Using

INSERT ALL 
 INTO PRODUCTOS_X_PLANES_CATEGORIA (PXG_ID, PXG_PRODUCTO, PXG_PLAN_CATEGORIA, PXG_VALOR) VALUES (NULL, 123456, 81, 10000) WHERE EXISTS (SELECT * FROM PRODUCTOS WHERE 123456 = PRO_ID)
 INTO PRODUCTOS_X_PLANES_CATEGORIA (PXG_ID, PXG_PRODUCTO, PXG_PLAN_CATEGORIA, PXG_VALOR) VALUES (NULL, 7890, 76, 11000) WHERE EXISTS (SELECT * FROM PRODUCTOS WHERE 7890 = PRO_ID)
SELECT * FROM   DUAL;

still results in

[Err] ORA-00928: missing SELECT keyword

You could use where:

INSERT INTO PRODUCTOS_X_PLANES_CATEGORIA 
    (PXG_ID, PXG_PRODUCTO, PXG_PLAN_CATEGORIA, PXG_VALOR) 
    SELECT NULL, 973082, 76, 10000
    FROM dual
    WHERE EXISTS (SELECT * FROM PRODUCTOS WHERE 973082 = PRO_ID)
