Controller file for SQL Loader

Question

Guys,
My data is coming in flat from some third party in the below format
1,Stewart,"Current Address: Street-A, Flat-507,  London, UK
Permanent Address: Street-B, Flat-201, London, UK"
2,Patrick,"Current Address: Street-A, Flat-507,  Bangalore, India
Permanent Address: Street-B, Flat-201, Delhi, India"
I want to load the data in a custom table by using a SQL loader program which will use a controller program. This program needs to populate the table in below manner
SEQ                                EMPLOYEE                                           ADDRESS INFORMATION
1                                     Stewart                                                  Current Address: Street-A, Flat-507,  London, UK
                                                                                                    Permanent Address: Street-B, Flat-201, London, UK
2                                     Patrick                                                  Current Address: Street-A, Flat-507,  Bangalore, India
                                                                                                    Permanent Address: Street-B, Flat-201, Delhi, India
Could you guys please help me in writing the controller file to read the data from file and populate the table as described above. Thanks.

Answer 1

It is a little hard to tell exactly what your data file looks like and what you want your results to be, due to this forum mangling things a bit and adding extra lines and such.  In general you can either use CONTINUEIF or CONCATENATE.  I have demonstrated both below.  When using CONTINUEIF, it assumes each additional line begins with the word "Permanent".  When using CONCATENATE, it assumes each two lines constitutes one record.  I have also used REPLACE to add a line feed in front of "Permanent", after it is removed during continuation or concatenation.
