Question

I figured out that we can retrieve records from an Oracle table with batch inputs as follows:

SELECT 
    * 
FROM
    invoices
WHERE
    (invoice_id, entity_id) IN 
                               (
                                   (1, 101), 
                                   (2, 102), 
                                   (3, 102)
                               )

Now, I need to fire a query where the input for one of the columns is immaterial, but still be able to do batch querying.

E.g.

SELECT 
    * 
FROM
    invoices
WHERE
    (invoice_id, entity_id, vendor_id) IN 
                               (
                                   (1, 101, 201), 
                                   (2, 102, 202), 
                                   -- no criteria on vendor_id for the tuple below
                                   (3, 102)   
                               )

If I run this query, the query engine reports the following error:

ERROR at line 1:
ORA-00920: invalid relational operator

Is it possible to do such a query in the first place? If so, how?

Oracle: Expression Lists:

The number of expressions in each set must match the number of
expressions before the operator in the comparison condition or before
the IN keyword in the membership condition.

You can separate these conditions:

SELECT 
    * 
FROM
    invoices
WHERE
    (invoice_id, entity_id, vendor_id) IN 
                               (
                                   (1, 101, 201), 
                                   (2, 102, 202)
                               )
    or 
    (invoice_id, entity_id) IN 
                               (
                                   -- no criteria on vendor_id for the tuple below
                                   (3, 102)   
                               )
