This is a really weird problem. When I create a new DB from a script I'm getting extra tables added. These aren't system type tables but regular tables that look like they may have come from a past project. There are 3 of them, each with 2 columns, either ints or nchar(10) with no keys, constraints, triggers, or indices.
I have no idea where this is coming from or how I can fix it. Right now I just delete the tables but it's a bit annoying and I'd like to fix the issue.
Here is a script I wrote that reproduces the error:
CREATE DATABASE X;
GO
USE X;
GO
CREATE TABLE Y(
YId INT IDENTITY CONSTRAINT pk_yid PRIMARY KEY(YId));
GO
CREATE TABLE Z(
ZId INT IDENTITY CONSTRAINT pk_zid PRIMARY KEY(ZId));
GO
After I run this script my DB is created, but it has 5 tables instead of 2.
Running SELECT * FROM INFORMATION_SCHEMA.TABLES
just lists my extra tables as BASE TABLE, exactly the same as the ones I defined (all other columns are the same as well).
This is happening on SQL Server 2008 R2
(Microsoft SQL Server Management Studio 10.50.2500.0)
