Asked by: popcornguy

I am receving this error.

[Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] You cannot add or change a record because a related record is required in table 'Recipes'.  
 
The error occurred in line 32
 
30 : , <cfqueryparam cfsqltype="cf_sql_varchar" value="#form.Amount#">
31 : , <cfqueryparam cfsqltype="cf_sql_integer" value="#form.MeasurementID#">
32 : , <cfqueryparam cfsqltype="cf_sql_longvarchar" value="#form.IngredientNotes#">
33 : )
34 : </cfquery>

 



The recipesID is the PK in Recipes table and a FK in the RecipeContents table. I'm not sure where I went wrong hefre but would apreciate the help.

Here is the query on the Insert page..
<cftransaction>
<cfquery name="insertRecipe" datasource="busy">
INSERT INTO Recipes
(RecipeTypeID, RecipeName, Instruction)
VALUES
(
  <cfqueryparam cfsqltype="cf_sql_integer"  value="#form.RecipeTypeID#">
, <cfqueryparam cfsqltype="cf_sql_varchar" value="#form.RecipeName#">
, <cfqueryparam cfsqltype="cf_sql_longvarchar" value="#form.Instruction#"> 
)
 
</cfquery>
<cfquery name="selectNewRecipeID" datasource="busy">
SELECT MAX(RecipeID + 1) AS newid FROM Recipes
</cfquery>
</cftransaction>
 
<cfset newRecipeID =  selectNewRecipeID.newid>
 
<cfquery name="insertRecipeContents" datasource="busy">
INSERT INTO RecipeContents
(RecipeID, IngredientID, Amount, MeasurementID, IngredientNotes)
VALUES
(
  <cfqueryparam cfsqltype="cf_sql_integer" value="#newRecipeID#">
, <cfqueryparam cfsqltype="cf_sql_integer" value="#form.IngredientID#">
, <cfqueryparam cfsqltype="cf_sql_varchar" value="#form.Amount#">
, <cfqueryparam cfsqltype="cf_sql_integer" value="#form.MeasurementID#">
, <cfqueryparam cfsqltype="cf_sql_longvarchar" value="#form.IngredientNotes#">
)
</cfquery>

What that means is that the initial record is not being seen by the code.  Are you using the update method to be sure the record is saved?

 

by: MaureenGouldPosted on 2008-12-29 at 22:14:38ID: 23260873

Never mind.  I see your mistake.  It's actually my fault.  Remove the + 1 on the new ID and you should be fine.

 

by: pratima_mcsPosted on 2008-12-29 at 22:17:13ID: 23260877

when you are selecting SELECT MAX(RecipeID + 1) AS newid FROM Recipes
at the same time you need to insert on record in Recipes table to add this PK.


It will only insert value in RecipeContents when this MAX(RecipeID + 1) AS newid   present in Recipes table

 

by: digicidalPosted on 2008-12-29 at 22:18:43ID: 23260882

Not sure if this will work, but the first thing I would try is to roll the whole thing up in your <cftransaction> block so that it will all be run as a single entry.  At a guess, it is erroring on the fact that when it tries to insert the second record (despite the fact that you ARE putting in the related record first) that it doesn't see the related record as existing.  I'm not totally sure how this works in Access, since I just use SQL and usually write stored procs for this sort of action.  CF is great, but if it's pure SQL it's usually faster just to do it in SQL exclusively.  I haven't worked in Access in ages, but there is probably something equivalent to a stored proc in access... they used to be scripts, dunno now though - hopefully someone with more Access knowledge can chime in on that front.

 

by: digicidalPosted on 2008-12-29 at 22:20:39ID: 23260886

Ah... good catch Maureen... that's exactly the case... I missed the +1.

Since you've already inserted the record into Recipies the Max RecipeID is the one you just inserted... so you don't need to add one to it.  (just to clarify)

 

by: popcornguyPosted on 2008-12-29 at 22:28:31ID: 23260903

I followed the advice of Maureengould and removed the +1, this seems to be moving me forward I am
now getting the following error.

Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] The INSERT INTO statement contains the following unknown field name: 'RecipeID'. Make sure you have typed the name correctly, and try the operation again.  
 
The error occurred in C:\ColdFusion8\wwwroot\busytimeDinners\addrecipe1.cfm: line 41
 
39 : VALUES
40 : (
41 :   <cfqueryparam value="#newRecipeID#">
42 : )
43 : </cfquery>

 

 

by: pratima_mcsPosted on 2008-12-29 at 22:32:24ID: 23260911


Ithink you need to change this in values

<cfqueryparam cfsqltype="cf_sql_integer" value="#selectNewRecipeID#">
