Hi guys!I'm currently making a database project and I want to update an access database.
I connected the database using this sql command
'select*from word'
And I tryied to update the database using this code

VB

ds.tables('word').rows(0).item(1)="cat"
Dim cb as new oledb.oledbcommandbuilder(da)
da.update(ds,"word")

da is a data adapter
ds is a data set
My problem is it giving me an error in runtime.
Any ideas?
-Regards

Update:
Here is the error message.
"Dynamic Sql generation for the update command is not supported against a select command that does not return any key column information"
Can u help me?

It seems your database table has no Primary Key defined. Set a Primary Key on your table and try again.
Here's how: Create or modify a primary key - Access[^]
