Conditional multiple loading by SQL Loader

Question

Hi All,
I am trying to load data from flat files to multiple tables. However, the tables are related and I want that if a record is rejected while loading for one table, similar records should be rejected too.
For instance, I have two tables EMP_INFO and EMP_LEAVE in which I want to load data:
EmpID Fname Lname (EMP_INFO record)
34002 Rahul Agarwal
EmpID Casual Medical (EMP_LEAVE record)
34002 5 2
I want that if any record above fails, all records having 34002 EmpID should not be loaded.
However, I must mention that the table EMP_LEAVE does not contain records for all employees. This is the reason why I cannot arrange the flat file in a single-line structure and load in this way from CTL file:
INTO TABLE emp_info
(EmpID POSITION(1:10) CHAR,
Fname POSITION(12:22) CHAR)
INTO TABLE emp_leave
(EmpID POSITION(1:10) CHAR,
Casual POSITION(25:27) INTEGER EXTERNAL)
because for most employees leave columns would be blank. Only for those employees where leave is not blank, do I want the above conditional loading.
Any pointers much appreciated. Thanks.
Best,
Rahul.

Answer 1

Hi Rahul,
this can be only a suggestion...
You have table A that is the master and B is the detail.
Your flat file contains records pertinent to table A and B
Data of parent objects are indicated before children objects.
Data in B table must be discarted if parent record in table A is not found.
Using those assumptions, You can define integrity constraint (FK) on the table B versus table A PK.
Then, raise the errors accepted in data loading, so if a parent record is not loaded or found, also child records are rejected.
Hope this helps
