Render a reference to this SqlColumn
Concrete methods
Derives a new column with a different owner with this column as underlying.
Derives a new column with a different owner with this column as underlying.
Used to represent columns on the outside of subqueries and common table expressions. Note that column aliases are tracked across derivation so that derived columns will continue to refer to the same underlying data irrespective of renaming.

Calculate a hash code value for the object.
Calculate a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)
) yet
not be equal (o1.equals(o2)
returns false
). A degenerate implementation could always return 0
.
However, it is required that if two objects are equal (o1.equals(o2)
returns true
) that they have
identical hash codes (o1.hashCode.equals(o2.hashCode)
). Therefore, when overriding this method, be sure
to verify that the behavior is consistent with the equals
method.

- Returns:
the hash code value for this object.
