Generate Mapping of multiple tMySQLOutput control with foreign keys
I have created a job to populate dataware house fact and dimension tables from another transactional database. (Attached is the image databasejob.jpg)
From tMYSQLInput I used a complex query to populate the data from source database.
Every tMYSQLOutput dentos a separte table which populate through tMap(Attached is screen shot tMapMapping.jpg).
Following are the populated tables.
-location (have autogenerated key)
-product (have autogenerated key)
-member (have autogenerated key)
-time (have autogenerated key)
-salesfact (It contains reference of all above tables keys as foreign keys.)
When I execute the job data populated in all tables but all foreign key references are empty in table salesfact.
How I can do it?
Do I need to use tJDBCOutput, tJava, tJavaOutput or some other control to populate data in all tables ?
Really appreciate your prompt replies.

Re: Generate Mapping of multiple tMySQLOutput control with foreign keys
You will need to do this in two steps:
1) populate all dimension tables

onSubjobOK
|
2) populate fact table, joining to newly populated dimension tables to retrieve keys
Also, it is not necessary to use the variables table to map values to different outputs of your tmap-- you can accomplish this directly--- (i.e. var.itemName can be row1.itemName)
