D

PK

Primary key constraint

TR

DML trigger

UQ

Unique constraint

1

F

Foreign key constraint

Need to be dropped before tables, as described below.

2

V

View

Should be dropped before tables, since they can have direct or indirect SCHEMABINDING.

FN

SQL scalar function

IF

SQL inline table-valued function

TF

SQL table-valued-function

3

P

Stored procedure

Need to be dropped before tables, but after views and functions (since procedures can reference views and functions, but can't be referenced by them except in rare cases using OPENQUERY()).

4

U

Table (user-defined)

Dropped after foreign keys and any type of module that can reference them with SCHEMABINDING.

5

TT

Table type

Dropped after tables and modules, but before old-style rules that could be bound to them. Table types need to be dropped before other types.

Alias types

6

SO

Sequence object

Dropped after tables/modules because they can't be dropped if any table or module references them.

R

Rule (old-style, stand-alone)

D

Old-style CREATE DEFAULT

Partition functions

7

Partition schemes

Can't be dropped until after partition functions.

8

SN

Synonym

I drop these toward the end because they can reference many of the items above (though this entity is not really prone to any issues on its own, unless you have external references pointing at them).

9

Schemas

I drop these almost last because almost all entities above can belong to a certain schema. For any entities you want to keep but move to a different schema, you'll need to first use ALTER SCHEMA ... TRANSFER.

10

Roles and Users

For users you don't want to keep, you'll need to first remove them from user-defined role membership and ownership, as well as ownership of any schemas. 

(For users you do want to keep, you may also want to remove any inappropriate permissions, but I'll deal with that in a separate post.) 

For roles you don't want to keep, you'll need to first remove any members; but you can't remove members who also happen to own roles.
