Hi Gurus,

Detail Requirement:
In Standard attachment form I have requirement to show only the attachment files which are Web Page type. That means, when User open the attachment form he can only see the attachment which are type of Web Page.

DB adpater wraps the parameter by ' (apostrophe), so using IN clause it becomes '1,2,3,4,5.........n' and the query returns nothing.
You need to use below query in DB Adpater
select attributes,attributes2 from table name where partnumber in (WITH VALUE_LIST AS
(SELECT ? val FROM dual)
SELECT SUBSTR(val, (decode(LEVEL, 1, 0, instr(val, ',', 1, LEVEL -1)) + 1), (decode(instr(val, ',', 1, LEVEL) -1, -1, LENGTH(val), instr(val, ',', 1, LEVEL) -1)) -(decode(LEVEL, 1, 0, instr(val, ',', 1, LEVEL -1)) + 1) + 1) a
FROM VALUE_LIST CONNECT BY LEVEL <=
(SELECT(LENGTH(val) -LENGTH(REPLACE(val, ',', NULL)))
FROM VALUE_LIST) + 1)
Value of <partnumber> tag can be mapped to DB Adapter Inputvariable.
If you create a very big value list for IN query (greater than 4000 characters) you will get ORA-01704: string literal too long error. In that case you need to break value list and invoke this query multiple times.
