Is it possible for Oracle sqlldr to accept a TNS entry as an instance qualifier in Oracle 10 and 11?

Is it possible to use a fully qualified TNS entry using sqlldr bundled with Oracle 10/11?

For example, in SQLPlus:

    sqlplus user/password@(description=(address=(host=localhost)(protocol=tcp)(port=1521))(connect_data=(sid=orcl))) @script.sql

But using sqlldr (SQL Loader) there appear to be issues with using the TNS entry directly. Specifically:

  开发者_StackOverflow中文版  sqlldr user/password@(description=(address=(host=localhost)(protocol=tcp)(port=1521))(connect_data=(sid=orcl))) bad='bad_file.txt' control='control.ctl' data='data.txt' log='log.txt' direct='true'

Here is the error message produced:

    LRM-00116: syntax error at 'address' following '('

    SQL*Loader-100: Syntax error on command-line

Attempting to encapsulate the TNS entry in quotes produces the same error.

Had a look at the sqlldr documentation, and attempted to use the 'userid' command-line argument to no avail. Specifically:

sqlldr userid='user/password@(description=(address=(host=localhost)(protocol=tcp)(port=1521))(connect_data=(sid=orcl)))' bad='bad.txt' control='control.ctl' data='data.txt' log='log.txt' direct='true'
LRM-00116: syntax error at 'password@(' following '='

It makes sense that Oracle would hope to coerce the user to a local instance to mitigate I/O in pushing data to a remote host. But the deviation in supported syntax is not so intuitive. Anyone else experience similar issues?

fwiw, this guy posted a solution to this problem

http://www.simplemancomplexmachine.com/2011/10/sqlldr-one-liner-to-remote-database.html

Yes there is a one-line solution and you can use a TNS connect string to do this from the command line. The key is formatting the connection string a little different as it must be quoted. Additionally the quotes and parentheses must be escaped (backslashes):

sqlldr userid=dbuser@\"\(description=\(address=\(host=remote.db.com\)\(protocol=tcp\)\(port=1521\)\)\(connect_data=\(sid=dbsid\)\)\)\"/dbpass control=controlfilename.ctl data=data.csv

Note that in the original blog post he had a space in front of '/dbpass'. This causes sqlldr to give the error:

LRM-00112: multiple values not allowed for parameter 'userid'

Have you tried the ezconnect format to connect to a remote db using sqlldr ?

e.g:

sqlldr user/password@//localhost:1521/orcl bad='bad_file.txt' control='control.ctl' data='data.txt' log='log.txt' direct='true'   

see: http://www.orafaq.com/wiki/EZCONNECT

Looks like you need to escape characters like '(', ')' and '=' with the escape character '\' (i.e. backslash) as explained in here.

You can also try:

sqlldr user/password@TNS:(description=(address=(host=localhost)(protocol=tcp)(port=1521))(connect_data=(sid=orcl))) bad='bad_file.txt' control='control.ctl' data='data.txt' log='log.txt' direct='true'

Kelvin is 100 % Correct. It worked for me

You can execute sql loader with below command without making a tns entry

sqlldr userid/password@//host:port/SERVICE_NAME bad='/PATH/FILENAME.bad' control='/PATH/FILENAME.ctl' data='/PATH/FILENAME.csv' log='/PATH/FILENAME.log' direct='true'

The only thing that worked for me was using two kinds of quotes:

sqlldr user/password@'"(description=(address=(host=localhost)(protocol=tcp)(port=1521))(connect_data=(sid=orcl)))"' bad='bad_file.txt' control='control.ctl' data='data.txt' log='log.txt' direct='true'

Single quoting the whole not-so-ezconnect worked for me in a DOS batch script and on the command line:

sqlldr 'user/password@(description=(address=(host=localhost)(protocol=tcp)(port=1521))(connect_data=(sid=orcl)))' control='control.ctl' data='data.txt'

I was able to fix the issue by running the same command with no spaces in connection string and using ' as escape character in normal command prompt (CMD) in windows server.

The same command in powershell still throw error
