Hi,

As per requirment i need to load data from a flat file and at the end i need to call a stored proc to update a table with total number of rows successfully loaded.

For ex: i have a data file as below:
HEADER,123,01/01/2014
X,A0100,100.00,ABC 
X,B0200,233.12,XYZ
A,AAAAA,332.22,SHHH COMPANY
TRILER,2,3


So, My Control file will only look for records HEADER,X,TRAILER reocrds

Once i load i need to update a table (on the TRAILER record).

I wronte a stored function which calls a stored procedure to perform DML... but errored out
Record 2716: Rejected - Error on table TEMP_A, column TOT_RECORDS.
ORA-14552: cannot perform a DDL, commit or rollback inside a query or DML 



Edited by Lalit : Added code tags wherever required

>>I wronte a stored function which calls a stored procedure to perform DML... but errored out
Issue is with the stored procedure. we cannot comment on what we cannot see.
>>update a table with total number of rows successfully loaded
Just do it. Separately.
Please post your table DDL and a valid sample datafile

As you can see, you cannot do any DML inside of a function, but you don't show us the function, so we have no idea what you are doing.

I'd say the easiest thing to do is just an external table for your datafile and then you can count the records in there based on a condition or load them into another table and do to it what you would like.

I am having a hard time following what you really are trying to do and what happened.

[edit] fixed typo which changed context of response.

The following uses two SQL*Loader runs with two control files. The first run loads only records where the first column = 'X' into the target table. The second run uses the log file from the first run and extracts the number of rows successfully loaded and loads that number into the tot_records column of the temp_a table.


SCOTT@orcl12c> host type data_file.csv
HEADER,123,01/01/2014
X,A0100,100.00,ABC
X,B0200,233.12,XYZ
A,AAAAA,332.22,SHHH COMPANY
TRAILER,2,3

SCOTT@orcl12c> host type test.ctl
load data
into table target_table
when col1='X'
fields terminated by ','
trailing nullcols
(col1, col2, col3, col4)

SCOTT@orcl12c> create table target_table
  2    (col1  varchar2(4),
  3     col2  varchar2(5),
  4     col3  number,
  5     col4  varchar2(12))
  6  /

Table created.

SCOTT@orcl12c> create table temp_a
  2    (tot_records     number)
  3  /

Table created.

SCOTT@orcl12c> host sqlldr scott/tiger control=test1.ctl data=data_file.csv log=test1.log

Thanks Barbara. That was awesome. So, can you show the test2.ctl file content please.

Sorry, I didn't mean to leave that out. Here it is.

-- test2.ctl:
load data
into table temp_a
when col2='Rows successfully loaded.'
fields terminated by whitespace
( tot_records position(1) terminated by whitespace
, col2        filler      terminated by '\n')

... I have another task, which is, to store the file name processed though SQL Loader. Environment details: Oracle 10g/Windows.

The Scenario,
Front End (: .Net ) will call control file by passing the file name (for example: a.ctl datafile=c:\x.dat'). Control file should accept that file name and store in table.


You could pass the file name to a windows batch file that would concatenate the filename to each row of the data in that file and output the result in another file. You could then use that resulting output file in your SQ*Loader control file. You could use wildcards in the file name, so you can specify multiple files or files with the same naming convention. Please see the example below.

SCOTT@orcl12c> -- data file:
SCOTT@orcl12c> host type x.dat
HEADER,123,01/01/2014
X,A0100,100.00,ABC
X,B0200,233.12,XYZ
A,AAAAA,332.22,SHHH COMPANY
TRAILER,2,3

SCOTT@orcl12c> -- control file:
SCOTT@orcl12c> host type test.ctl
load data
into table target_table
when col1='X'
fields terminated by ','
trailing nullcols
(col1, col2, col3, col4)

SCOTT@orcl12c> create table target_table
  2    (filename  varchar2(30),
  3     col1      varchar2(4),
  4     col2      varchar2(5),
  5     col3      number,
  6     col4      varchar2(12))
  7  /

Table created.

SCOTT@orcl12c> -- batch file to merge data with file names and load it with file names:
SCOTT@orcl12c> host type add_file_name.bat
findstr "^" x*.dat >output.txt
sqlldr scott/tiger control=test1.ctl data=output.txt log=test1.log

SCOTT@orcl12c> -- run of above batch file:
SCOTT@orcl12c> host add_file_name.bat

C:\my_oracle_files>findstr "^" x*.dat  1>output.txt

C:\my_oracle_files>sqlldr scott/tiger control=test1.ctl data=output.txt log=test1.log
