Help! MySQL LEFT JOIN probelm in Perl

2 New Member
Hi All

I have a sticky problem! Its a LEFT JOIN sql statement which works fine in MySQL but not when called in Perl. Any ideas?

I have 2 tables: campaigns & companies. I'm trying to join them so that all columns of both tables are returned when 2 fields match across the tables and some additional tests in the first table. It works fine in MySQL but returns an empty set when called in Perl. Is there some limitation in Perl or a better way to format the command for it to work from Perl?

Here is the SQL statement which works fine when tried directly inside MySQL:
Expand|Select|Wrap|Line Numbers
  1. SELECT * FROM campaigns 
  2. LEFT JOIN companies 
  3.   ON campaigns.DestinationURL=companies.Website 
  4. WHERE (
  5.   campaigns.BudgetAvailable>0 
  6.   AND campaigns.SearchWebs LIKE "%google%"
  7. ORDER BY campaigns.MaxPayPerClick DESC LIMIT 6
And here is the Perl code:
Expand|Select|Wrap|Line Numbers
  1. my $query = qq{ SELECT * FROM campaigns LEFT JOIN companies ON campaigns.DestinationURL=companies.Website WHERE (campaigns.BudgetAvailable>0 AND campaigns.SearchWebs LIKE "%$website%") ORDER BY campaigns.MaxPayPerClick DESC LIMIT 6 };
where $website has the variable passed into it.

Please help me if you can!!!

Thanks.

Is there a way to get help the way you get it from the Python interpreter (eg, 'help(dir)' gives help on the 'dir' command) in the module cmd.Cmd? I know how to add commands and help text to cmd.Cmd but I would also like to get the man-page-like help for classes and functions. Does anyone know how to do that? Thanks. Sarir

Missing Help Files When I enter "recordset" as the keyword and search the Visual Basic Help index, I get many topics of interest in the resulting list. But there isn't any information available from clicking on many of the available topics (mostly methods but some properties are also unavailable). This same problem occurs with many, if not most, keywords. Is there any way I can activate these "missing" help topics? HELP!
