Lookup Issue in ODI

Question

Hi there,
I need to do lookup in source tables and insert the result to target table in an ODI interface.
I have source table s_table1 with:
s_table1 columns:
LV1_ID_COLUMN, LV2_ID_COLUMN, LV3_ID_COLUMN, ... LV15_ID_COLUMN
I need to use the LVx_ID column value to lookup its name and other value from another source table s_table2:
s_table2:
ID_COLUMN NAME VALUE
======== ===== ======
LV1_ID LV1_NAME LV1_VALUE
LV2_ID LV2_NAME LV2_VALUE
LV3_ID LV3_NAME LV3_VALUE
And target table is:
t_table:
LV1_ID_COLUMN, LV1_NAME_COLUMN, LV1_VALUE_COLUMN, LV2_ID_COLUMN, LV2_NAME_COLUMN, LV2_VALUE_COLUMN, LV3_ID_COLUMN, LV3_NAME_COLUMN, LV3_VALUE_COLUMN ...
What would be the best way to do this? Looks to me if in interface I imported the source table s_tables2 15 times, I can join each id column in s_table1 with id column in s_table2 and get the name/value for each ID_COLUMN in s_table1, but it would be a mess.
My requirement is a simple lookup with an input data, one lookup table, and a couple of output data. What would be the right way to do it in ODI?
Thanks!

Answer 1

Hi-
If I understood your requirement completely then this would be an ideal solution. Please let me know if not.
You can create a single interface with 2 source tables (s1, s2 joined on the basis of s_table1.LV1_ID_COLUMN=s_table2.LV1_ID) and 1 target datastore.
Then in your target datastore mapping, you can give like this:
LV1_ID
LV1_NAME
LV1_VALUE
LV2_ID
LV2_NAME
LV2_VALUE
