Обсуждение: Problem with character in strings

-----BEGIN PGP SIGNED MESSAGE-----

Hi to all,

As explained in a previous mail today, I'm porting an Informix based
application to PostgreSQL. Now this work is nearly done, but there is
still a problem with the character ' in strings. I'm using 'ecpg' for
develop. Whenever a ' appears in a string that should be inserted into the
database, it crashes with the error 'too many arguments in line'. I found
out that the ' is interpreted as 'end of string'. How's that possible? I'm
using normal variables in the application. Is there a workaround possible?

However. I know I can precede every ' with a backslash, but that would make
my code completely incompatible to the still supported Informix. Can I
change the delimiter for strings in some way?

Some data: PostgreSQL 6.5.1 Linux 2.2.7 (SuSE 6.1) Intel Pentium egcs-2.91.66

Actually, ' is the end of string character, not end of line.

To comment out the ', use ''.  For example, change the string
Rusty's Home
to 
Rusty''s Home.

Are you sure that the above won't work with Informix?  It's pretty
standard.

Is there anybody out there?

Wouldn't the sentence "I want to put a hyphen between the words Fish
and And and And and Chips in my Fish-And-Chips sign" have been clearer if
quotation marks had been placed before Fish, and between Fish and and, and
and and And, and And and and, and and and And, and And and and, and and
and Chips, as well as after Chips?
