If you ever need to find that elusive information in an oracle database to load into TM1 via TI, then the following sql is very useful:
SELECT * FROM ALL_TAB_COLUMNS
WHERE OWNER = ''
SELECT * FROM ALL_TAB_COLUMNS
WHERE COLUMN_NAME LIKE '% %'
SELECT * FROM ALL_TAB_COLUMNS
WHERE table_name= ''
Basically you can use the ALL_TAB_COLUMNS table to find info on all the tables in an oracle database. i.e. you know there is a table that holds GST info but you are not sure where, then execute the sql:
SELECT * FROM ALL_TAB_COLUMNS
WHERE COLUMN_NAME LIKE '%GST%'
I would also recommend that anyone who needs to get data out of Oracle uses the tool Toad, which I find invaluable.
