Hi niger007,
(no points for me)
See http://msdn2.microsoft.com
Database objects include all tables, views, stored procedures, extended stored procedures, triggers, rules, defaults, and constraints. The sum of the number of all these objects in a database cannot exceed 2,147,483,647.
Cheers!
use [urdatabase]
select * from sysobjects
xtype is a column in sysobjects
the values it can hold
C = CHECK constraint
D = Default or DEFAULT constraint
F = FOREIGN KEY constraint
L = Log
FN = Scalar function
IF = Inlined table-function
P = Stored procedure
PK = PRIMARY KEY constraint (type is K)
RF = Replication filter stored procedure
S = System table
TF = Table function
TR = Trigger
U = User table
UQ = UNIQUE constraint (type is K)
V = View
X = Extended stored procedure
select count(*) from sysobjects where xtype = 'u' will give count of usertables
Put simply, there is no practical limit on the amount of tables you can have. Considering that SQL caters for 2 billion objects, if you simply took the amount of possible objet types (16) and divide by that you STILL have 134,217,727 - a very large number.
To find that in your documentation, simply go Start-->Program Files-->Microsoft SQL Server (or SQL Server 2005, depending on your version) and click Books Online (if you have installed it from the CD, otherwise download it). For SQL 2005, the documentation is in a sub-folder called documentation.
