Coldfusion  and MS SQL Order By and Save Sort Order

Posted on 2008-06-18

Last Modified: 2009-08-07
I have some Coldfusion code that outputs a directory. My challenge is to have three options to sort by. I have a integer field sortorder in the table. It already has a value on how to sort the records. I have a javascript drop down with the three options to sort by. All sort by options are fields in the table. Two of the fields are varchar the names are DIVISION and DEPT. The third is a integer field SORTORDER. When I sort by DIVISION I want it to change the SORTORDER integer field in ascending number order no matter what sortorder number was given when the record was added.

Hey, if you are still having this problem, can you post your code?  It would make it easier to answer I believe.  For instance, how are you displaying the grid (table)?  Are you using cfgrid?  Are you using client-side sorting or server-side, etc..

If you want a quick solution, check out cfgrid.  Attached is the sample code (modified a bit) from the CFDocs.  Or else http://developer.yahoo.com/yui/datatable/ is good if you know a bit of js.  Otherwise if you post your code I can help more..
    <cfgrid 
        name = "FirstGrid" 
        width = "500"
        query = "DIRECTORY_VARIABLE_HERE" colheaderbold="Yes"
        rowHeaders = "No" >
        
        <!--- cfgridcolumn tags arrange the table and control the display. --->
        <!--- select="No" does not seem to have any effect!!! --->
        <cfgridcolumn name = "VARIABLE_NAMES_HERE" header = "Department" Select="No" width="75"
            textcolor="blue" bold="Yes">
        <cfgridcolumn name = "CorNumber" header = "Course ##" Select="No" width="65">
        <cfgridcolumn name = "CorName" header = "Name" width="125">
        <cfgridcolumn name = "CorLevel" header = "Level" width="85">
        <cfgridcolumn name = "CorDesc" header = "Description" width="125">
    </cfgrid>

unfortunately not in html format.  Does Flash though... The cf AJAX scripts were all based on a real early version of yui.
If you 've never checked out the yui library, it's pretty cool.  I used it to output a qry, allow the user to edit each field, and then pass the data back and it didn't take long at all.

here is their basic example:
http://developer.yahoo.com/yui/examples/datatable/dt_basic.html
The data for the table is here (you only need the small bookOrders part):
http://developer.yahoo.com/yui/examples/datatable/assets/js/data.js

Your code would be something like what I have below..

Believe me, if it looks confusing it is really not.  If you don't know scripting or OO languages it can be freaky... but you can just look at the <b>key:"varName"</b> fields and substitute your variables.  And then remove formatters if you don't want them (but you probably will).

If you know js and are familiar with yui, I also combined this example in the code:
http://developer.yahoo.com/yui/examples/datatable/dt_clientsorting.html
It sorts on state, then areacode.

Best of luck, sorry I couldn't be more of a help.
