Hi all.

I have a problem regarding the escaping of backslash characters with SQL Anywhere dbs. I experience the problem inside a PB Datawindow, but it's merely a db problem, so I will describe it in terms of pure SQL.

Suppose I create a dummy table such as:

CREATE TABLE dummy (filepath char(50));

Then I do the following insert:

INSERT INTO dummy VALUES ('\\theserver\newfolder\thepath');

Well, if I then do a SELECT * FROM dummy I get:

\theserverewfolder\thepath

That is because the \\ and \n have been escaped and trasformed to single backslash (\\) and nothing (\n). Luckily the \t has not been escaped (who knows why?).

If I do the same with a SQL Server database all works ok (no escaping). With MySQL there's an option (NO_BACKSLASH_ESCAPES) that can be sent at connection time to avoid this behaviour.

What about SQL Anywhere? Do you know a way to avoid this?

Thank you much,
Luca
