Repository tables Expression query

In a mapping with multiple expression transformations and multiple unconnected lookups, it is difficult for you to identify the expressions calling these unconnected lookups. This SQL will give you what you are looking for.

select w.instance_name,
from opb_widget_expr f,
opb_expression g,
opb_widget_inst w,
opb_mapping m
where f.expr_id = g.expr_id
and f.widget_id = w.widget_id
and w.widget_type = 5
and w.mapping_id = m.mapping_id
and m.mapping_name = 'm_Open_Trades_Target_load'

It is very useful.. To add something more following query can used to know the transformations used in the mapping by giving the folder and the mapping name

select wid.widget_name from opb_widget wid,opb_subject sub,opb_mapping mapp
where wid.subject_id = sub.subj_id and
wid.ru_parent_id = mapp.mapping_id and
and sub.subj_name = 'Folder name'
and mapp.mapping_name = 'Mapping Name'
