The number one offender is the lack of a primary key in your data when you try to post it back to the DB. I have been sporadically getting a "Row cannot be located for updating" error. In this instance, I am just building a desktop application. To do this it must be able to find the record in your database that corresponds to the record you are editing.

If you dont have a primary key, then the db manager tries to figure out which row should be updated by seeing if he can find one that looks much like the one that you just changed in the query object. I am not able to reproduce it, although it occurs most often when I am trying to delete a record. The error message you are getting indicates that ADO can't find the record to be deleted.

2004-01-06 AM delphi88 First of all best wishes to everyone. In my application, I use a t Ado Data Set with a simple Command Text like "select * from Customer".

Recently added an insert/update trigger to a table in SQL Server to populate some fields from a 2nd table.

I use ADODataset (Cursor Location = cl Use Client and Cursor Type = ct Static).

When I add a new record the Autoincrement field is not filled with the proper value but always with 0. This doesn't happen if Cursor Location is set to cl Use Server and Cursor Type to ct Key Set, but I don't know if this the right choice for a stand alone application.

If I set it to Integer, I cannot set the relationship in Access.

At this point any operation fails (inserting a new record = duplication of the primary key; deleting the record = error message "Row cannot be located for updating."; refreshing = the same message). You can imagine what a nightmare when I also create a detail table connected with the master. Thank you very much and sorry for the long message.

The only way to get the proper value is to close and relaunch the program, so to read again the database. And in this case the provider even doesn't not support a server cursor ("Current provider does not support the necessary interfaces for sorting or filtering").

I know this is possible, but cannot find out how this is done from D7. I have a form that has a couple of grids and databound controls.

Without this, ADO will default to taking *all* fields as the key and stuff these in the SQL WHERE clause it constructs on the fly. The datasources are set to some TADOQuery's which have master datasources too.

I've also tried setting the 'Update Criteria' property of the dataset to ad Criteria Key in ADOData Set. Actually, I found a way to overcome the problem, probably not very elegant and maybe resource-consuming. ADOData Set1After Post(Data Set: TData Set); var Bookmark: TBookmark; begin with ADODataset1 do begin Bookmark := Get Bookmark; Disable Controls; Requery(); Goto Bookmark(Bookmark); Free Bookmark(Bookmark); Enable Controls; end; end; Jet 4.0 is the last update available from Microsoft download.
