Code Inspection: Insert NULL into NOT NULL column

Reports cases when you insert NULL values into columns that accept only NOT NULL values.

Example (Microsoft SQL Server):

CREATE TABLE br2 (
id INT NOT NULL,
col1 NVARCHAR (20) NOT NULL,
col2 NVARCHAR (20) NOT NULL,
);
--
INSERT INTO br2 (id, col1, col2)
VALUES (1, NULL, NULL);

You cannot insert NULL values in col1 and col2 because they are defined as NOT NULL. If you run the script as is, you will receive an error. To fix this code, replace NULL in the VALUES part with some values (for example, 42 and 'bird').

INSERT INTO br2 (id, col1, col2)
VALUES (1, 42, 'bird');
