Re: [JDBC] MS Access to PostgreSQL

Hi Shelby,

I don't think the problem isn't with the backslashes. They are escaped and
seem to be working fine e.g. to insert a backslash in Access I had to use
one escape character ('\\') whereas in PostgreSQL four backslashes ('\\\\')
are required. The line that inserts the % is as follows...

String aPath = group.getPath() + aOldGroupName + "\\%";

It just doesn't seem to be having the same effect in PostgreSQL as in
Access.

I suspect that, unlike Access, PostgreSQL will
intrepret C-style escape sequences (ie: \r, \n, \t) so
you'll need to properly escape the backslash in aPath
like so:

folder1\\folder2\\folder3
