Hello,

1)Is there a way to load two tables from two input files in one control file?

I have two control files.


LOAD DATA
INFILE 'C:\name.txt'
BADFILE 'C:\name.bad'
DISCARDFILE 'C:\name.dsc'
APPEND
INTO emp_tab
fields terminated by ";"
TRAILING NULLCOLS
( Emp_id ,
name,
age)



LOAD DATA
INFILE 'C:\job.txt'
BADFILE 'C:\job.bad'
DISCARDFILE 'C:\job.dsc'
APPEND
INTO job_tab
fields terminated by ";"
TRAILING NULLCOLS
( job_id ,
title,
salary)




Can i load emp_tab and job_table using one control file and two input files name.txt and job.txt?

2)Is there a way to pass the path as a parameter in the control file?

In the job below, when i execute the sqlldr , can I pass C:/job.txt as an input instead of specifying it in control file?


Thanks
Nammu

control file is a plain static text file; so the short answer is "NO!"

I have to wonder why, but yes, it can be done as demonstrated below. However, you have to have something that can be used in a WHEN clause to determine which table the data should be loaded into, unless the data for one table is of different types and lengths that would be rejected for the other table.

Yes, you could use a control file and two command lines as shown below.

-- control file:
LOAD DATA
APPEND INTO TABLE emp_tab WHEN whichtable='E'
FIELDS TERMINATED BY ";" TRAILING NULLCOLS
(whichtable FILLER, emp_id, name, age)
INTO TABLE job_tab WHEN whichtable='J'
FIELDS TERMINATED BY ";" TRAILING NULLCOLS
(whichtable FILLER POSITION(1), job_id, title, salary)


-- command lines:
HOST SQLLDR scott/tiger CONTROL=test.ctl LOG=test1.log DATA='name.txt'
HOST SQLLDR scott/tiger CONTROL=test.ctl LOG=test2.log DATA='job.txt'
