notNull

Adds a NOT NULL constraint to the column.

This ensures that the column cannot have a NULL value. The function modifies the column's generic type to a non-nullable T, reflecting the constraint at compile time.

This can be used to pass nullable column to a non-nullable function argument. Virtually acting as non-null type casting.

Example

select(
     MIN(
         LENGTH(Employees.firstName),
         Employees.longCol.notNull(),
     )
).execute()
