[PERSISTENCE CLASS] SELECT OPTION in WHERE statement

Hi Gurus,

I would like to know how could I code the WHERE statement with a SELECT OPTION, in Persistence Class ?

Currenlty, I would like to code this kind of request :

          DELETE FROM      ziTab

                         WHERE   zdate IN so_date.      

Do you know, how could I code it ?

Many thx for helps.

Best regards.

Rachid.
