Key Field Problem

Running Cold Fusion 4.0 with MS-Access on a stand-alone test box, I am trying to run a DoEdit but I keep getting an error saying that I have not identified a primary key in the table. I have done this, deleted and re-entered the database in the ODBC datasources and verified it. I still get this error!
Any suggestions?

Hi jacquard,

I've never heard of a DoEdit, but it sounds interesting. Is it an Access 2000 function?

There is no ColdFusion Function called DoEdit what are you trying to do that is not working?

Sorry, what I meant to type was that I am trying to do an edit of some records using CFUPDATE. The "DoEdit" is just a call.

If your table has a primary key, then you must send the primary key field value into the CFUPDATE as well..

For example:

PAGE1.CFM

<FORM ACTION="page2.cfm" METHOD="POST">
      <INPUT TYPE="Hidden" NAME="userid" VALUE="1">
      <INPUT TYPE="Hidden" NAME="password" VALUE="test">
      <INPUT TYPE="Submit">
</FORM>

PAGE2.CFM

<CFUPDATE DATASOURCE="mydatasource" TABLENAME="mytablename" DBTYPE="ODBC" FORMFIELDS="userid, password">

If you don't want to use a primary key, you should be able to get around this limitation by just using CFQUERY with an update statement:

<!--- Update all records --->
<CFQUERY NAME="myquery" DATASOURCE="mydatasource">

UPDATE mytablename
SET password = 'test'

</CFQUERY>

I hope that is on the right track of what you are asking..if not, can you post some sample code?

Hiz!

Jacquard, can you show us the exact error message are you getting. It's also a plus if you can show us the table structure and the cfm code your are getting in trouble.

Thanks,
cfmrulez!

OK...I think I may have stumbled onto the problem but in doing so uncovered another. My original query read:
<CFUPDATE DATASOURCE="training" TABLENAME="RJITF Courses" dbtype="odbc">

<CFQUERY NAME="GetData" DATASOURCE="training">
SELECT *
FROM RJITF Courses
ORDER BY RecordID
</CFQUERY>

I found that Cold Fusion didn't like spaces in the "TABLENAME" field nor did it like brackets, quotes, or anything else.

After renaming the table to "RJITFCourses" I now get the error:
"ODBC Error Code=22005 (Error in assignment)"

In the debug mode it shows the SQL as:
SQL="UPDATE RJITFCourses SET 'DURATION' =?, 'TARGET'=?, 'PLACE'=?, 'COURSENAME'=?, 'CODE'=?, 'REP_CODE'=?, 'COURSEDESC'=?, WHERE 'RecordID'=?"

Any help before I lose more hair?

thanks

You may want to use a standard SQL query instead of the CFUPDATE. It's much easier
to debug due to being able to see what's going on:

<CFQUERY NAME="updateData" DATASOURCE="training" DEBUG>
    UPDATE      RJITFCourses
    SET         DURATION = '#FORM.duration#',
                TARGET = '#FORM.TARGET#',
                PLACE = '#FORM.PLACE#',
                COURSENAME = '#FORM.COURSENAME#',
                CODE = '#FORM.CODE#',
                REP_CODE = '#FORM.REP_CODE#',
                COURSEDESC = '#FORM.coursedesc#'
    WHERE       RecordID = '#FORM.RecordID#'
</CFQUERY>

Be sure to remove the single quotes around the #FORM.variable# if the destination field is numeric. So, if "REP_CODE" is a numeric field in Access, then you would use:

    REP_CODE = #FORM.REP_CODE#
   
....instead of '#FORM.REP_CODE#'

I'm not sure what your form variable names are, so the above were just guesses.

Hope that helps.

Although this answer did not resolve the problem, it did put me on the right track to finding the solution myself.

The problem was an error in my code where I included a "hidden" field statement where I shouldn't have.

Many thanks to Dain and everyone else who provided input.
