When using the SQLADAPTER component, it was found that VS did not automatically generate the SQL statement for INSERT, UPDATE, and DELETE. At first, I thought it was a BUG of VS, and later others reminded that there may be no primary key, when the data table has no primary key. Is there a statement for updating a data table, so it is necessary to remember the primary key when defining a data sheet, in fact, this is also a rule that must be remembered when designing a database.
