Nope, I'll elaborate the result after the select. I need directly the SUM for each hour from output SQL select!
Maybe using grouping (and SUM) by partial, but I don't know how to implement yet!

Well, I found myself a solution, it was so simple!!! :-)
Code:
SELECT data, SUM(`tot`) as SUM, COUNT(tot) As HOUR FROM `data` GROUP BY MID(data, 8,2)
how would I write a command line that creates a new file named stuff.txt in the current working directory which contains the number of directories in the current working directory, followed by the number of empty files in the current working directory, followed by the name of the working directory?

Hi,
I have an array of strings. Each string has 4 comma separated values. I am binding this array to a SQL where I am required to do an INSERT after grouping.
The binding is done as :

How do you do grouping in grep? Here's how I tried it at first:
egrep 'qualit(y|ies)' /usr/share/dict/words
-bash: syntax error near unexpected token `('
I'm using GNUgrep, and I found this on their site. grep regular expression syntax
So I tried this:
egrep 'qualit\(y\|ies\)'... (2 Replies)

Hello,
I would like to group/sort a file of records by a particular field and then count how many records belong in that grouping.
For example say I have the following data:

EFGH|"ZZZ"|"Date"|"1"|"Y"|"ABC"|""|BB... (14 Replies)

SQL::Translator::Parser(3pm) User Contributed Perl Documentation SQL::Translator::Parser(3pm)NAME
SQL::Translator::Parser - describes how to write a parser
DESCRIPTION
Parser modules that get invoked by SQL::Translator need to implement a single function: parse. This function will be called by the
SQL::Translator instance as $class::parse($tr, $data_as_string), where $tr is a SQL::Translator instance. Other than that, the classes are
free to define any helper functions, or use any design pattern internally that make the most sense.
When the parser has determined what exists, it will communicate the structure to the producer through the SQL::Translator::Schema object.
This object can be retrieved from the translator (the first argument pass to parse) by calling the schema method:
my $schema = $tr->schema;
The Schema object has methods for adding tables, fields, indices, etc. For more information, consult the docs for SQL::Translator::Schema
and its related modules. For examples of how this works, examine the source code for existing SQL::Translator::Parser::* modules.
