To add a primary key to a materialized view in Oracle, you can use the following steps:

  1. Create the materialized view without a primary key first.
  2. Alter the materialized view to add a primary key constraint.


Here is an example:


Step 1: Create the materialized view without a primary key:

1
2
3
4
CREATE MATERIALIZED VIEW mv_name
AS
SELECT column1, column2
FROM table_name;


Step 2: Alter the materialized view to add a primary key constraint:

1
2
ALTER MATERIALIZED VIEW mv_name
ADD CONSTRAINT pk_name PRIMARY KEY (column1);


Replace mv_name with the name of your materialized view, table_name with the name of the table you are using in the materialized view, pk_name with the name you want to give to the primary key constraint, and column1 with the column you want to use as the primary key.


After running these commands, your materialized view will have a primary key constraint added to it.
