Sql loader ?. CSV file need 2 load to multi tbls

Question

I have a CSV file i.e.
3 columns on file (qy_type_cd,cd_description,tablename)
example data:
PAST,Past Program Quantity,MASTER_QY
FUT_PEACE,Future Peace Program Quantity,MASTER_QY
TM_PHAS_USE,Time Phased Users Quantity,ADDITIVE_QY
MISTR_RPR,MISTR Repair Quantity,USAGE_QY
I need to load to 3 tables. Tables have two columns (qy_type,description).
How can i read the tablename from csv file and load the qy_type_cd and cd_description INTO a table
something like this. but I dont know the syntax
into table api_mstr_qy
fields terminated by ","
when tablename ='MASTER_QY'
(qy_type,description,tablename)

Answer 1

First you need to create a directory that corresponds to where the csv file is located
create directory mydir as 'c:\loaddata\'
Then you need to define the metadata for the
external table:
CREATE TABLE myExternal (
qy_type_cd varchar2,
cd_description varchar2,
tablename varchar2
ORGANIZATION EXTERNAL
(DEFAULT DIRECTORY mydir
ACCESS PARAMETERS
(RECORDS DELIMITED BY NEWLINE
BADFILE 'bad_external'
LOGDILE 'log_external'
FIELDS TERMINATED BY ','
qy_type_cd char,
cd_description char,
tablename char
LOCATION (mycsv.csv))
PARALLEL 1 --PUT 2 or the amount of clustered servers you want to use for the process
REJECT LIMIT 1;
Now you are able to run selects on this table
ie: select * from myExternal will produce:
PAST,Past Program Quantity,MASTER_QY
FUT_PEACE,Future Peace Program Quantity,MASTER_QY
TM_PHAS_USE,Time Phased Users Quantity,ADDITIVE_QY
MISTR_RPR,MISTR Repair Quantity,USAGE_QY
So here is where you use the conditional INSERT:
INSERT
WHEN tablename ='MASTER_QY' THEN
     INTO api_mstr_qy (qy_type,description,tablename)
     VALUES (qy_type,description,tablename)
WHEN tablename = 'OTHER' THEN
FROM myExternal
