RE: Using Custom Fill Methods on BO

Trent L. Taylor — Thu, 25 Jan 2007 17:49:30 GMT

Are you creating the stored procedure? If so, what do your CRUD settings look like on your BO? Last, what does the SP look like?

Note: Please do not post the entire SP text in the text window. Upload it as an attachment so we can get a more accurate view.

Using Custom Fill Methods on BO

Richard Keller — Thu, 25 Jan 2007 17:49:30 GMT

When creating a Custom Fill Method does the Data Retrieval order have to match the Business Object Definition order or will the BO auto map the fields to the properties based on the column names?

Thanks for your help.

Richard

Taking the variable out of the SP does not change anything

the only way to make it work is to change the SP's that get the data and make sure reseller is not in the data returned.

OK, you can remove the @reseller field from the update command. The business object will only attempt to update fields that are part of the mapped table (those contained in the AllFieldsList). Since your business object was mapped to Customers, it does not think that @reseller should be supplied because it doesn't think it's part of the updating table. So, whatever the structure of the data table inside the business object, it's only going to update the fields that are part of the mapped table on SQL Server.

Are you trying to update the Reseller.reseller field? Or are you trying to just update the fields within the Customers table?

here are the fileshopfully you will find something.

The image of the debug file that you posted is a little too small to be legible. Could you zip it and the partial class for your business object and post them here?

Don't post it here if there's a password in the connection string... email it to me through the forum.

Sorry "No the AllFieldsList property does bot show it as a property"

Should have said that reselller is not a member of AllFieldsList .

The AllFieldsList has 22 memebers of which reselller is not one.

There are 24 variables in the stored proc @Customer_UID_ORGPK and @reseller are added for strataframe

RE: Using Custom Fill Methods on BO

StrataFrame Team — Thu, 25 Jan 2007 09:54:02 GMT

The AllFieldsList is a property on the BusinessLayer class, so, if you put a breakpoint within one of your methods on your business object, you can test the AllFieldsList property to see if it contains "reseller". When the DAL builds the UPDATE query for a business object, it iterates through the columns on the business object and adds them to the update command only if the column is included in the AllFieldsList of the business object.

The next release also contains some additional functionality for the business objects to allow them to exclude fields from updates. The feature is currently in testing by a few of our users and will be included in the next release.

Hete is my select statement form sql server Sp

SELECT cs.*, rs.reseller
FROM Customers cs JOIN
Reseller rs ON cs.reseller_UID = rs.reseller_UID
WHERE Customer_UID = @Customer_UID

If I remove ",rs.reseller" Then the save works in edit mode (still do not know why add works)

here is the error dump

DataLayerSavingException
Invalid column name 'reseller'.
SqlException
Invalid column name 'reseller'.

Does the AllFieldsList property of your business object contain that field? Also, what is the full exception that you're getting? Having the stack trace will help point me in the right direction.

RE: Using Custom Fill Methods on BO

Bradley Marston — Wed, 24 Jan 2007 11:59:21 GMT

I have a BO that is mapped to a table. To fill the object I call

the FillbyStoredProc method. The stored proc that is called adds 1 additional field

from another table all seems fine except when i try to call my update stored proc

then I seem to get a data layer exception on this added field, Oddly it does not happen on calling my insert proc

Gary is correct. The order of the columns in the returned result set does not matter. Also, the columns returned to not have to exactly match the field properties on the business object. On a per-column basis, what Gary said is correct... the name and the data type have to match. But, you can have more or fewer columns in the return result set than the strong typed field properties on the business object. If you have a property that doesn't have a corresponding column in the DataTable, you cannot access it (because there's no data behind the property), so don't touch it in code if the field is not in the DataTable. However, if you have a column in the table that doesn't have a field property, you can access it through the .Item (default/indexer) property like this (comes in handy for joins and aggregate fields like COUNTs and such):

myBO("MyField") = "some value" '-- VB

myBO["MyField"] = "some value"; //-- C#

I assume you are referring to the order of the columns in your returned result set? If so, it doesn't matter to the SF business object. It will read and write the data to the column in the inner DataTable (referenced by the CurrentDataTable property). As long as they are named the same and are of the same datatype/precision, you will be good to go.
