Question

Conversion failed when converting the nvarchar value 'A' to data type int.

Asked by: Shawnaraxi

I'm trying to insert answers from a form. The fields were generated dynamically. Why am I getting this error?

<cfloop list="#form['QuizQuestion' & ViewQuestions.QuizQuestionID]#" index="QuizQuestionID">

<cfquery name="addParticipantDetails" datasource="#application.DSHome#" username="#application.dbuserHome#" password="#application.dbpassHome#">
INSERT INTO tblQuizParticipantDetails
           (ParticipantID
           ,QuizQuestionID
           ,QuizParticipantAnswer
           )    
     VALUES
           (
           <CFQUERYPARAM Value="#addParticipant.ParticipantID#">,
           <CFQUERYPARAM Value="#QuizQuestionID#">,
           <CFQUERYPARAM cfsqltype="cf_sql_varchar" Value="#form['QuizQuestion' & ViewQuestions.QuizQuestionID]#">
           )
</cfquery>

</cfloop>

A is not and int its a letter or char/varchar/nvarchar.  You can't put a into an int field in a database.

 

by: ShawnaraxiPosted on 2009-09-03 at 14:05:59ID: 25254945

but the field in the db (sql server 2005) is not an int filed. It is nvarchar(MAX)

 

by: 8080_DiverPosted on 2009-09-03 at 14:15:09ID: 25255024

Shawnaraxi,

Can you post the DDL for creating the table so that we can see what the Table Definition is?

Also, look at the following line:

<CFQUERYPARAM cfsqltype="cf_sql_varchar" Value="#form['QuizQuestion' & ViewQuestions.QuizQuestionID]#">

Is it possible that there is an implicit conversion involved in that line?

 

by: Jones911Posted on 2009-09-03 at 14:25:31ID: 25255117

Are you sure your not accidentally gettign a :

 <CFQUERYPARAM Value="#addParticipant.ParticipantID#">,
           <CFQUERYPARAM Value="#QuizQuestionID#">,

a in one of these is they are meant to be int?

Try dump then both before the query.

 

by: ShawnaraxiPosted on 2009-09-03 at 14:46:43ID: 25255297

after testing without the variables it turns out the variables are not giving as expected.

these are both giving the actual answers in the form
<CFQUERYPARAM Value="#QuizQuestionID#">,
<CFQUERYPARAM cfsqltype="cf_sql_varchar" Value="#form['QuizQuestion' & ViewQuestions.QuizQuestionID]#">

Inonther words QuizQuestionID is giving the answer (nvarchar) rather than an int.

so I have to go back to the form to fix this....will post more in a minute

 

by: ShawnaraxiPosted on 2009-09-03 at 15:01:50ID: 25255408

by: ShawnaraxiPosted on 2009-09-03 at 16:28:58ID: 25255912

the A,b,c values are going into a field with an nvarchar attribute. this shouldn't be a problem.

 

by: Jones911Posted on 2009-09-03 at 16:35:41ID: 25255957

Ok

<CFQUERYPARAM  cfsqltype="cf_sql_varchar"  Value="#QuizQuestionID#" />

 

by: ShawnaraxiPosted on 2009-09-03 at 16:50:20ID: 25256021

the problem is not really to convert the data type. they are all fine.

It is more in how I have set up my variable names in the form and how I retreive them in the action page. I'm working on it but any comments are welcome.

 

by: ShawnaraxiPosted on 2009-09-03 at 17:54:02ID: 31624674

reworked the form and all is well. types match now. thx
