How to use bitand operator?

How can I use bitand so I can turn on TESTING only when the TYPE_NAME is SOFTWARE or S/W REQUEST

SQL> select * from state
2 ;

STATEID STATE_NAME STATE_FOR PB_WEB_VISIBLE_TYPE
---------- -------------------------------- ---------- -------------------
1 SCHEDULED 0 0
2 DEFERRED 0 0
3 TESTING 0 0

SQL> select * from type;

TYPEID TYPE_NAME
---------- --------------------------------
0 SOFTWARE
1 S/W REQUEST
2 SYSTEM

Here's an example of what I found.. but I am not sure how to use it...
SQL> select decode(bitand( 24117, power(2,4)), power(2,4), '1', '0') from dual;

DECODE(BITAND(24117,POWER(2,4)
--------------------------------
1

Help please...
Thanks

I think I have to di someting like this-
SQL> select state_name from web_state where decode(bitand(pb_web_visible_type, power(2,0)), power(
2,0), 1,0) = 1;

But I get a ....no rows selected... message.

sdesar,
I'm having some trouble following your request. Your examples show a bitand on PB_WEB_VISIBLE_TYPE which is 0 in the cases you have (from state). And the table WEB_STATE isn't described anywhere. Finally, your follow-up post changes your "power" from 2,4 to 2,0 (or, from 16 to 1).

Could you try posting your requirement again, or at least more of what your dealing with? Like, what does it mean to "turn testing on"?

Good luck!

Oops sorry I meant STATE table.

I want to show STATE 'TESTING only when the TYPE is SOFTWARE or S/W REQUEST

SQL> select * from web_state;

STATEID STATE_NAME TYPEID PB_WEB_VISIBLE_TYPE
---------- --------- ---------- -------------------
1 SCHEDULED 0 0
2 DEFERRED 0 0
3 TESTING 0 0
5 CLOSED 0 0
2 DEFERRED 1 0
3 TESTING 1 0
5 CLOSED 1 0
0 OPEN 1 0
5 CLOSED 2 0
Currently, web_state is a lookup table and I can tell what TYPES have what STATES.

Thefore, question is how can I use the 'bitand' to display only TESTING if 'TYPEID' is 0 or 1 ie software or software request.

I need to know what kind of select shold I use so I can modifiy the JSP to show only TESTING if type is 0 or 1.

I hope this clarifies it a bit.
Awaiting suggestions.
Thanks

I have a jsp that that a TYPE comboBox... this lists only SOFTWARE, S/W REQUEST, SYSTEM.

I want the STATE combox to display - OPEN, TESTING, CLOSED only if the TYPE is SOFTWARE or S/W REQUEST.
else
display only OPEN CLOSED.

When I enter this JSP I know the TYPE of ticket it is .. ie SOFTWARE or S/W REQUEST or SYSTEM

therefore instead of hardcoding the logic in the jsp.. I am wondering how and if I can use the bitand operator to set the bits to true, false.

Thanks
