Row cannot be located for updating mysql

I am getting an EDatabase error that says 'Row cannot be located for updating'.

What causes this error and how can I handle it in my exception handling.

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.

However, my table has a primary key defined and rows can be uniquely identified using this key (an Int). Recently added an insert/update trigger to a table in SQL Server to populate some fields from a 2nd table.

I've read some time ago in this NG (I believe) that you can limit the ADO where statement construct by informing the ADO recordset about this primary key (or rather: dropping the other fields). Since then inserting a new row gives the error "Row cannot be located for updating".

He has to scan the whole db to find all possible candidates and if he finds too many, or none, he cant update anything. The default for ADO generating SQL is to use all the fields and values you originally queried from the database to find the in your database. Is there a way to set the SQL generation to just use the key? I delete one record and when I reopen my app I find that two have been deleted instead. "Brian Bushay Team B" Yes, I have a single column meaningless integer key for each table. I was about to resort to submitting the SQL myself, using the statement that you showed below.

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

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.

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.
