Hi,

Assume that i have two tables tab1 and tab2.
I want to load the data into tab1 using data file "data1".
Their is one column in tab1 whose data is not available directly
in data file,whose value can found by combination of unique column in tab1(which is foreign key for tab2) and tab2.


Please help me to resolve the issue.

structure of tables
tab1
name dept_no dept_name
tab2
dept_no dept_name

here i want to load tab1(dept_name) from tab2(dept_no from tab1)
Here dept_name is not available in data file.

One (easy) way would be to use "external tables" feature (if your database version supports it); because, doing so, you'd be able to insert records into tables using (PL/)SQL language. In your case, it would require a simple join.

Use an external table instead of SQL*Loader, then you have the full power of SQL to load.
How to do it depends on what you have in the file, information you didn't give us.

You could also create a function that accepts the foreign key value as a parameter and returns the desired data, then use that function in your SQL*Loader control file, but if your data is large, it might not be as efficient.
