I'm having a bit of trouble replacing sed's delimiter from a slash to a pipe.

This works...

Code:
sed '/INSERT INTO/s/\${TD_LOAD_DB}/NUC_PL_LOAD/g' sql_file.sql

But this doesn't

Code:
sed "|INSERT INTO|s|\${TD_LOAD_DB}|NUC_PL_LOAD|g" sql_file.sql

Although if i remove the INSERT INTO pattern, the delimiter works...

Code:
sed 's|\${TD_LOAD_DB}|NUC_PL_LOAD|g' sql_file.sql

Any ideas?
When using a character other than slash character ("/") as the delimiter in a context address, the first delimiter must be preceded by a backslash character ("\"), so try:
Code:
sed "\|INSERT INTO|s|\${TD_LOAD_DB}|NUC_PL_LOAD|g" sql_file.sql

Since there is no / in "INSERT INTO", why not use the default delimiter? (Note that the delimiter used for the context address and the delimiter used in the substitute command do not have to be the same character.)

Assuming that you're trying to search for the string specified by the variable TD_LOAD_DB, why do you have the backslash before the dollar sign?

nwbpset

NWBPSET(1)							      nwbpset								NWBPSET(1)

NAME

       nwbpset - Create a bindery property or set its value

SYNOPSIS

       nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ]

DESCRIPTION

       nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by
       the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with

       As another example, look at the following command line:

	 nwbpvalues -t 1 -o supervisor -p user_defaults -c |
	 sed '2s/.*/ME/'|
	 sed '3s/.*/LOGIN_CONTROL/'|
	 nwbpset

       With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user  object
       'me'.

	 nwbpvalues -t 1 -o me -p login_control -c |
	 sed '9s/.*/ff/'|
	 nwbpset

       This command disables the user object me.

       Feel free to contribute other examples!

       nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information.
       Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the user name to use for login.

       -P password
	  password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to  the  server,  nwbpset
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.
