I have a scenario where the data file has values separated by ^.While loading this data into the table using sql loader I want to convert it into multiple lines.eg:

data file:

1|1013 park ridge~12345~irving|

2|2013 park ridge~12345~irving|

3|1013 park ridge|




while loading it into table i want the data like




ID ADDRESS

1 "1013 park ridge

12345

irving"

2 "2013 park ridge

12345

irving"

.....

My control file says:


load data
infile "/usr2/home2/adistest/h91ftp/temp/owb_test/owb_test1.csv"
preserve blanks INTO TABLE owbrep.owb_test1

TRUNCATE
fields terminated by '|' TRAILING NULLCOLS
(
id,
address
)



Please suggest what should I do?

SQLLOADER does not manipulate the data being loaded.
Consider doing the same via EXTERNAL TABLE REPLACE the tilde character with a newline charater

I posted the following on the OTN forums:

https://forums.oracle.com/thread/2568886

You can use the REPLACE function in your control file to replace whatever character, like ~ in your sample data, is where the newline should be with whatever your newline is on your system, like chr(10) as in the example below.

SCOTT@orcl12c_11gR2> host type owb_test1.csv
1|1013 park ridge~12345~irving|
2|2013 park ridge~12345~irving|
3|1013 park ridge|

SCOTT@orcl12c_11gR2> host type test.ctl
load data
infile "owb_test1.csv"
preserve blanks INTO TABLE owb_test1
TRUNCATE
fields terminated by '|' TRAILING NULLCOLS
(
id,
address "REPLACE (:address, '~', CHR(10))"
)

SCOTT@orcl12c_11gR2> create table owb_test1
  2    (id       number,
  3     address  varchar2(60))
  4  /

Table created.

SCOTT@orcl12c_11gR2> host sqlldr scott/tiger control=test.ctl log=test.log

My problem is not with the sql loader.It is behaving correctly.My problem is the above procedure using utl_file which writes wrong date format to the csv file and it also truncates the time from the date.Please suggest.

Similarly..
source table had:10/8/0007 9:52:45 AM
utl_file wrote in csv file:08-OCT-07(so utl_file is not behaving correctly)
So my sql loader treated as 10/8/2007

I guess I need new glasses since I can't see any procedure; above or elsewhere.

>source table had:10/8/0007 9:52:45 AM
How are we supposed to know/see such details?

Since we don't have your tables or data, we can't run, test, debug, or improve posted code.

The problem is probably in the value of the p_sql_query parameter that is passed. If it selects a date column, then the default nls_date_format is probably being applied, instead of using to_char to get the desired format.

The second problem has nothing to do with the first and was apparently posted on the wrong thread and refers to the problem and procedure in this thread:
