nullable-required-column (GN013)

Automatic fix is available.

What it does

Checks for existence of not null constraint on required columns.

Why not?

If a column has been specified as required then it should not be nullable. Having a required column as nullable is an anti-pattern and should be avoided.

When should you?

Never.

Use instead:

Set the required column as Not Null.

Configuration

required-columns: List of required columns along with their data types.
