Why do you have one table without a primary key? Add it with autoincrement at least , and you will we able to create your cdt.

If you are going to update the table, then why not just add an auto-increment id column?

We cannot update data in view, data should be update in the Table then how we can update the table?

If you are creating a view, simply add a new column for the artificial or composite key.

CREATE VIEW my_view AS
SELECT col1, col2, CONCAT(col1, '_', col2) AS composite_key
FROM my_table;

How can we update the data in that table if we are creating the view?

Not. Appian requires a primary key. If you do not have one, you could create a view that adds an artificial PK.
