Full-text search with '#' and '+' in keyword

Searches by keyword containing pound '#' and plus '+' signs using a Sql Server 2005's Full-Text index, and functions 'freetext' and 'containstable'  does not yield correct results matching the term, such as 'C#' and 'C++'. The returned results seems equivalent of ones returned by terms without the pound and plus signs. 
Could anyone shed some light on this?

The normal way to handle this would be to have the word stemmer change the # to sharp and + to plus.  That way your searches can do the same thing.   But in most databases you would have to pre-parse your text before inserting it to clean up those works you know have special meaning.

Since both of those are symbols I am almost positive that SQL Server will consider them stops and not index them at all.  That would mean they are not in the fts index so you can't search them.

'do' won't 'do' if '/'
Greetings to All from Au, Have a NetWare Perl 5.8.4 and wanted to tweak File\Spec\NW.pm to try and standardise on '/' separators. If I run a test script (t/uni/lower.t) with an unmodified NW.pm, it calls t/uni/case.pl, that, in case.pl, (when the path separators are '\'), the $file is '..\lib\unicore\To\Lower.pl' and the following code portion works, with $simple getting a returned table: sub casetest { my ($base, $spec, $func) = @_; my $file = File::Spec->catfile(File::Spec->catdir(File::Spec->updir, "lib", &qu...

Cast from type ''''DBNull'''' to type ''''String'''' is not valid.
How do I avoid getting this error: Cast from type ''''DBNull'''' to type ''''String'''' is not valid. I am trying to get values from the database into a form for updating using a Datareader, SQL is set to allow nulls for certain fields as they are not required but the only way I can get the form to display is by adding a space in SQL. Is there another way around this? Check if it is equal to DBNull.Value first and if it is, don't do the cast.Stanley Tan theSpoke Blog Where in the code does it need to go?

table_info('','','','%') cannot return any types
I was recently confirming table_info special cases and discovered the case for getting table_types cannot work. table_info('','','','%') should return a list of table types but it returns a list of empty strings instead: my @types = $h->tables('', '', '', '%'); print "all types:\n", join("xxx\n", @types), "\n"; # should output something like: # "dbo" # "INFORMATION_SCHEMA" # "sys" # and actually outputs: xxx xxx It seems to be down to the following ...

'or' or 'union'
Hello I was just wondering, in general what is better to use, an 'or' clause in a select or a 'union' to join two selects together. Do both statements create work tables? Many thanks Alex I think OR will be better than union. because suppose u have 3 tables and using OR u can join table a and table b and table c so each table will have only one read. but using union you will join table a and table b and in another query of union u will use table (a or b) and table c so ur one read is more in union .

'IN' Clause or 'OR'
Hello, [1]: select * from TABLEA where COL1 IN('value1','value2''valu3'....) [2]:select * from TABLEA where COL1 = 'value1' OR COL1= 'value2' OR COL1='valu3'. TABLEA is a huge table and it has non-clustered index on COL1. Among the above 2 queries, which query will give me the better performance or fast response and WHY? What is the difference between 'IN' and 'OR' clauses as for as Sybase Optimization is concerned. Which is the better one to be used on huge tables. Thanks. Mac An IN list is treated ...

Paste as 'picture' or 'text'?!
We have 2 sets of machines that are behaving differently and cannot figure out why. The application is a PowerBuilder app, which uses an OLE control to paste it's contents into a large Word doc (the contents for the OLE control come from the DB and are in Word format). One set of machines (5 of them) execute this code and the resulting doc has all this pasted data as Word Text (just as if it were typed in). The other set of machines (3 of them) execute this same code and the resulting doc has large picture objects (or Word Document Objects?) that contain the Word Text inside of...
