Forespørgsel med kommaseparerede IN-parametre i PLSQL

SELECT * FROM Table1 WHERE   
Table1.PRODUCT LIKE ( select regexp_substr(I_PRODUCT,'[^,]+', 1, level) from dual
                     connect by regexp_substr(I_PRODUCT, '[^,]+', 1, level) is not null);

LIKE operatør ville mislykkes i ovenstående forespørgsel. Du skal bruge IN , som internt ville blive evalueret som flere ELLER .

Table1.PRODUCT IN ( select regexp_substr(I_PRODUCT,'[^,]+', 1, level) from dual
                     connect by regexp_substr(I_PRODUCT, '[^,]+', 1, level) is not null);

Rediger forespørgslen som:

WITH str_search AS
(
     select regexp_substr(I_PRODUCT,'[^,]+', 1, level) pattern from dual
     connect by regexp_substr(I_PRODUCT, '[^,]+', 1, level) is not null
)
SELECT   *
FROM     Table1
WHERE     EXISTS (
          SELECT     NULL
          FROM     str_search
          WHERE     tab.col     LIKE pattern
                 );
