SQL Loader [message #441324]

Hi
While importing data using sqlldr, we define as below for fixed length files :

empno POSITION(01:04) INTEGER EXTERNAL,
name POSITION(06:15) CHAR,
job POSITION(17:25) CHAR )

However, I have 31 columns and the flat file span across 2 lines for a single row. In this case how will i define POSITIONS for 2nd line for each row. Do i have to change something in input flat file ?
Or there is separate syntax for POSITION in this case ?

Regards
Naveen

Are you sure about this?

Post Operating System (OS) name & version for DB server system.
Post results of
SELECT * from v$version

You might need to change how the flat file gets created.

Check SQL*Loader documentation's Assembling Logical Records from Physical Records section which describes how to combine multiple physical records into a single logical record. Clauses that you'd use are CONCATENATE and CONTINUEIF.

On the other hand, if your records are the same fixed length, you could do something like this:

Example: The fixed length of each physical record is 80 characters first line plus 40 characters second line = ( 80 + 40 ) plus two (2) characters line terminator for unix or four (4) characters for windoze files.

Therefore the total physical record length (for unix) would be: 122 characters.

Your controlfile should look something like this:

LOAD DATA -- Etc ...
INFILE 'MyInfile.dat' "FIX 122"
INTO -- etc ...
empno POSITION(01:04) INTEGER EXTERNAL,
name POSITION(06:15) CHAR,
job POSITION(17:25) CHAR 
-- etc --
LF1 FILLER POSITION(81:81) CHAR, -- Optional, just for clarity
next_col POSITION (82:...)
-- etc --
)

Maybe it will work for you /forum/fa/1600/0/
