Hello,
I have a MySQL query in which I want to include a list of ID's from another table. On the website, people are able to add certain items, and people can then add those items to their favourites. I basically want to get the list of ID's of people who have favourited that item (this is a bit simplified, but this is what it boils dow...
(NOTE: This question is not about escaping queries, it's about escaping results)
I'm using GROUP_CONCAT to combine multiple rows into a comma delimited list. For example, assume I have the two (example) tables:
CREATE TABLE IF NOT EXISTS `Comment` (
`id` int(11) unsigned NOT NULL auto_increment,
`post_id` int(11) unsigned NOT NULL,
`na...
Somehow GROUP_CONCAT is able to round up six "pages" of an article (each stored as TEXT) and toss them into a single MEDIUMTEXT without losing any data, but there are some one-page
articles that are longer than normal (but still obviously fit within the TEXT data type) that lose a significant amount of data. Anyone know what's up?

I'm looking for the LINQ equivalent to the Sybase's LIST() or MySQL's group_concat()
It'll convert:

In short: Is there any way to sort the values in a GROUP_CONCAT statement?

The question is to get table column data and use it as a value list for IN function;
For this example I created 2 tables: movies and genres
Table "movies" contains 3 columns: id, name and genre.
Table "genres" contains 2 columns: id and name.

For performance,I need to set a limit for the GROUP_CONCAT,
and I need to know if there are rows not included.
How to do it?
EDIT
Let me provide a contrived example:
create table t(qid integer unsigned,name varchar(30));
insert into t value(1,'test1');
insert into t value(1,'test2');
insert into t value(1,'test3');

I somehow need this feature,but MySQL doesn't support it at this moment.
I'm using GROUP_CONCAT(CONCAT(...)) to generate a xml-like stuff.
But when the size exceeds the limit,the xml is just broken!
So I have to somehow make it only retrieve 5 rows !

I have a MySQL database in which each user has an account, and each account can have multiple permissions.
My ultimate goal is to end up with the account's username, and a comma-delimited list of permissions ids. There are two ways I can accomplish this:
SELECT a.username, GROUP_CONCAT(rp.permission_id) as permission_ids
FROM account ...

I want to order the results in a GROUP_CONCAT function. The problem is, that the selection in the GROUP_CONCAT-function is another function, like this (fantasy select):

FROM people a, stuff b, courses c

I would like to ask for opinion on making aggregate data by concatenating strings. If I have a column aggregate but I want to concatenate then in an aggregate column, which is faster in terms of performance? Doing one SQL then just aggregating then in the CODE. Or selecting the main data then querying one at a time.
For Example:
