查询多列中的多个值

Question

How would I search multiple (in this example, say 2) columns for an array of values?

For example, here is my table Documents :

1. DocNumber (varchar)
2. CompanyCode (varchar)
3. Data1 (varchar)
4. Data2 (varchar)
5. Data3 (varchar)

DocNumber and CompanyCode form the composite primary key of this table. Say I have a set of values which I want to search in the database such as:

DocNumber	CompanyCode
1001	101
1002	102
1004	103

How would I find these unique combinations in the table with one query?

I could use in :

select *
from Documents
where DocNumber in :docNumbers and CompanyCode in :companyCodes

But that would also return records with DocNumber 1001 and CompanyCode 102 (all combinations of the 2 lists). I want to avoid that.

I am using HANA DB (through a Spring Boot application).

The IN predicate also works with tuples. Please find a minimal example:

SELECT * 
FROM 
(
    SELECT 'A1' AS DOCNUMBER, 'A2' AS COMPANYCODE FROM DUMMY
)
WHERE (DOCNUMBER, COMPANYCODE) IN (('A1', 'A2'),('B1', 'B2'))

Further details and examples can be found in the documentation .
