Question

In CDT How to handle the table without having primary key?

If a database table do not have any primary key, then how we can handle this table in Appian CDT?

Brainy

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

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

Brainy

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;

Brainy

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.

Brainy

then how we can handle this table in Appian

By updating it to add a Primary Key column.
