automatically create update statement for view

I have a view in SQL server which is defined ast

SELECT ..... FROM tblmaster m JOIN tblreginfo r ON (m.account=r.account)

In my VB.net application, I can connect to the SQL server via ODBC and import tables and views.

However, when I import a table, the tableadapter.Update() command is created for me. For the view, it is not.

What should I do?

None of the tools that automatically generate UPDATE statements (TableAdapter, CommandBuilder) can do it on a multi-table query, because they do now know which of the tables you want to update. You might get the same problem with a table that does not have a primary key, because the tools have no way of identifying a unique row.

The solution is to build an UPDATE statement, assign it to a SqlCommand object and execute it through its ExecuteNonQuery method.

I hear what you are saying, and it makes sense. The only thing is that I actually can issue update statements via SQL Server or through the SSMS window.

What I'm saying is that SQL server seems to be smart enough to allow me to update the view and even smart enough to prohibit me from updating calculated columns in the view, but VB doesn't let me update it.
