Hi All
I am doing a normal SQL update against postgres.
Seems to be replacing \\ with \ when it gets saved in the database. eg.
\\machine\folder is being replaced with \machine
Any ideas?
Vaughn

The backslash (\) character is used to escape other characters from normal
interpretation, so you can have a text value: 'Richard\'s text' which means
during processing the backslash is removed.
If you want to actually have a backslash in your sql you'll need to escape it
too. So you'll have something like:
INSERT INTO foo (path) VALUES ('\\\\machine\\folder');
Most application languages offer something like a quote_sql() function which
handles all the details of this for you.
