Every CDT-mapped table/view has to have a primary key column or a unique column that can be treated as a primary key column. You need to alter the view definition to include a new incremental int column that you'll treat as a PK column.

It is saying "a_id" is missing

The data source schema does not match the type mappings: Schema-validation: missing column [a_id] in table [`View name`]

Steps performed:

1. Created a view

2. Created a CDT with the DB view.

3. Now, trying to add this CDT to the Datastore. It is giving the above error.

Can you please help here.

That is probably because the field names or something do not matches. You can click on the "More info" link towards the end of the line to understand what is wrong.

When we are adding the CDT that we have created from the DB view to the data store, it is showing as create to the table in the data store.

Can you please tell what to do here?

Add it to the DataStore, and create a constant that points to the newly added DSE. Create an expression rule and use a!queryEntity() function to query the data and finally use the ER in an interface to show the data in a grid.

Thank you, that CDT should be add it to the data store?

How do we mention the entity in the expression rule?

Hello Purvaja,

You will need a CDT, Expression rule that queries your data and an Interface. If you just want to display your data with no particular UI requirements, you can use a read only grid. You can use records as well but there might be a sync issue since you will be using view.
