Hi,
I thought it isn't possible to use a SqlDataAdapter and a Databound grid
when there isn't a 'real' primary key on the table.
Although, is there a way to use it, and define somewhere in the
SqlDataAdapter my own primary key on the table?
I can't add a primary key to the table, so I guess that's the only way to
find a solution?
Any help would be really appreciated!
Thans a lot in advance,
Pieter

Hi,
Yes, dataadapter doesn't require a primary key. It is required just by the
wizards to generate insert/update/delete statements.
Also, dataadapter has nothing to do with binding to table.

Pieter,
From where do you have that idea?

You can create your own CRUD statements and avoid creating a magic key.
Simply write the INSERT, UPDATE and DELETE statement rather than relying on
the DataAdapter to automagically create one for you. As long as the SQL for
all four statements is correct, you are up and running.

Hehe I don't know anymore.
But it's great that it seems I'm able do do use it, although with writing
the upate statements myself, but that's no problem.
thanks a lot!

Pieter,
You was not telling that you wanted to update (and therefore my question).
Despite all others answers won't I not know what to update or to delete when
I don't have that key. (Inserting will go when there is an autoincrementke y
or a Guid used for the uniqueidentifie r).
Just my thought,
Cor

I ran into a table that is used a lot. Well less than
100,000 records. Maybe not a lot of records but i believe
this table is used often. The table has 26 fields, 9 indexes
but no Primary Key at all!
There are no table relationships defined in this database, no
Natural keys, only Surrogate keys in the database.
1- Maybe an odd question but is it normal to have 1/3 of the
table's fields as indexes? Is this a valid question or it really

I've got a problem which I think may be a bug in Postgres, but I wonder if
I'm missing something. Two tables, A & B have foreign key relations to each

C, adds a row each in B & C. I get an integrity violation. All the foreign
keys are deferrable, and the stored procedure is called from within a
transaction with constraints deferred. (And the foreign keys do refer to...

There's some mention in the (old!) documentation that constraints such as foreign keys won't include data from inheriting tables, eg:
CREATE TABLE foo (
id SERIAL PRIMARY KEY
);
CREATE TABLE bar (
attribute integer NOT NULL
) INHERITS (foo);

Hi,
The SqlDataAdapter.FillSchema method will automatically setup things
like the primary keys, auto increment, etc based on the settings on the
SQL Server. However, if you create a datatable using the SQL statement
that joins together data from multiple data tables, then FillSchema
does not work (as much? at all??). For example, if I use the following
query:

Can someone tell me HOW to insert a automatic number after my user inserts new data from text boxes into the dataset. I keep getting this error:
Cannot insert the value NULL into column 'id', table; column does not allow nulls. INSERT fails. (ID IS MY KEY)
I can update & delete fine, but when I try to insert, I cannot figure out how to get the primary key inserted. I'm new @ this & I think I've confused myself....
