SQL Error: There is already an object named 'TPatients' in the database

Question

I cannot seem to figure out why I am getting the following error:

Msg 2714, Level 16, State 5, Line 56
There is already an object named 'TPatients' in the database.
Msg 1750, Level 16, State 1, Line 56
Could not create constraint or index. See previous errors.

Here is my Drop Table and Create Table SQL statements below. Whenever I execute, it says TPatients already exists, however I am not seeing it in the object explorer. I tried moving around the drop table statements, but could not get it to work.

--  Step #1 : Drop tables

IF OBJECT_ID ('TAppointments')      IS NOT NULL DROP TABLE TAppointments
IF OBJECT_ID ('TPatients')          IS NOT NULL DROP TABLE TPatients
IF OBJECT_ID ('TDoctors')           IS NOT NULL DROP TABLE TDoctors
IF OBJECT_ID ('TNurses')            IS NOT NULL DROP TABLE TNurses

Answer 1

The issue is because you are giving your constraints the same name as the table.

Give them a unique name, eg prefix with "PK_Tpatients" if it's a primary key.

Note that tables and constraints are all "objects" and as such need unique names.
