Description: SELECT problem with strings containing \
Details:
Hi,
Please refer to the DDL and data below:
When running a query such as:
select folder from public.folders
where lower(folder) like '%c:\\1%'
no rows are returned
However,
select folder from public.folders
where lower(folder) like '%c:%'
does work OK.
When the query string contains a \\ (escaped \) no results are returned.
Other combinations not containing this character work OK. I've tried without
the % wildcard without success so this does not appear to be the problem.
I've also tried it without the lower function either, still no luck. Using
the \\ to insert records works fine (as shown below).
Table DDL:
----------
create table public.folders(
folder varchar(255) ,
lastfolder varchar(255) ) with oids
Here are some INSERTS to populate data:
---------------------------------------
insert into public.folders values ('C:\\1\\', '1');
insert into public.folders values ('C:\\111\\', '111');
insert into public.folders values ('C:\\115x\\', '115x');
insert into public.folders values ('C:\\11tx\\', '11tx');
insert into public.folders values ('C:\\2005\\', '2005');
insert into public.folders values ('C:\\2005\\(12)December\\',
'(12)December');
insert into public.folders values ('C:\\2005\\(12)December\\051209\\',
'051209');
insert into public.folders values ('C:\\2005\\12 December\\', '12
December');
insert into public.folders values ('C:\\2005\\12 December\\12\\', '12');
insert into public.folders values ('C:\\776\\', '776');
