Write one DDL statement to add a new column AssignDate of date type in ProjAssignment table, which should allow no null values. Because there are already existing rows in the table which have no AssignDate data, your DDL statement must define a default value using current date in this column. When this DDL statement is executed, it will then update the AssignDate of every existing row with the default current date.

Check the explanation

Explanation:

A DLL can be classified as a library that comprises of code and data which can be used by more than one program at the same time.

a DDL statement in answering the question above can be seen below:

ALTER ProjAssignment ADD AssignDatw Date DEFAUT getdate() NOT NULL;

Default is keyword to set default date fetch by function getdate() i.e. current date.

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?
