I've been away from reports for a while, so I am a little rusty. Can someone explain to me what the below data represnts at the end of a sql statement/query when building an Oracle report and how it relates to the report?

&CP_ORG_WHERE
&CP_BUILDING_WHERE
&CP_ROOM_WHERE
&CP_EXCLUDE_FED_WHERE

Thanks
Anne

It looks like dynamically created WHERE clause. For example, if your query looks like

SELECT deptno, dname
FROM dept
&cp_org_where

you'd have to find where 'cp_org_where' is created. I presume it has something to do with user parameter(s) and could be defined in the AFTER-PARAMETER-FORM trigger (with possible use of a package/procedure/function).

It might look like this: if parameter's name is 'par_loc', then 'cpc_org_where' might look like

'WHERE loc = ' || :par_loc

which would then evaluate the whole query into

SELECT deptno, dname
FROM dept
WHERE loc = :par_loc
