I have an editable grid with a coule of labels and a delete-checkbox. Since I use e few left-joins in the datasource, I need to use a custom-delete. I used an SQL statement "DELETE FROM tbl_name WHERE field = {id}" with {id} defined.
CCS [2.2.3.60] adds "LIMIT 0, 100" to this statement, resulting in an error message! Why does CCS add this, and how do I remove it?
Any help would be appreciated

Dirk,
How you can repeat it? I cannot get the same results. What are the settings of "id" parameter and what exact sql you get?

Sorry, I also don't understand this problem and don't know why CCS would add such code to your SQL statement.
Please contact our support (link below) for more detailed analysis.

Probably without realizing it yourself, you gave me a very helpfull answer!
I inflicted this problem myself by adding a custom query function to class clsDBdbConn extends DB_MySQL (common.php)
I have overridden the standard query function to speed up database traffic; since I work with different servers for my databases and my website and I have tables with 10.000+ records, I thought it a bit useless to retrieve 10.000 records to display only (let's say) 25 of them...
The error I made was not checking for 'select' statements, which is corrected in the code here-below.
I'm curious to your reaction; would this bit of code be a good addition to CCS in the future?
Regards, Dirk
===============
function query($Query_String) {
if (isset($this->PageSize) && isset($this->AbsolutePage) && strtolower(substr($Query_String,0,6) == "select")) {
if ($this->PageSize != 0 && $this->AbsolutePage != 0 && $Query_String != CCBuildSQL($this->CountSQL, $this->Where, "")) { $limit = " LIMIT ".(($this->AbsolutePage - 1)*$this->PageSize).",".$this->PageSize;
} else {
$limit = "";
}
} else {
$limit = "";
}
parent::query($Query_String.$limit);
}

Without analyzing and testing your code in detail, I don't know how/if it will work with all components in CCS.
However, we are planning to add LIMIT support for MySQL.

Dirk,
I just obtained information that we plan to implement LIMIT within a week or two and release an update.
(there are related issues/tasks, regarding implementing this with custom SQL, as well as in ASP, Java, .NET, etc.)
