Maximum Capacity Specifications
The first table specifies maximum capacities that are the same for all
editions of Microsoft® SQL ServerT 2000. The second and third tables specify
capacities that vary by edition of SQL Server 2000 and the operating system.

This table specifies the maximum sizes and numbers of various objects
defined in Microsoft SQL Server databases, or referenced in Transact-SQL
statements. The table does not include Microsoft® SQL Server 2000T Windows®
CE Edition.

1 Network Packet Size is the size of the tabular data scheme (TDS) packets
used to communicate between applications and the relational database engine.
The default packet size is 4 KB, and is controlled by the network packet
size configuration option.
2 The maximum number of bytes in any key cannot exceed 900 in SQL Server
2000. You can define a key using variable-length columns whose maximum sizes
add up to more than 900, provided no row is ever inserted with more than 900
bytes of data in those columns. For more information, see Maximum Size of
Index Keys.
3 The size of a database cannot exceed 2 GB when using the SQL Server 2000
Desktop Engine or the Microsoft Data Engine (MSDE) 1.0.
4 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.

Maximum Numbers of Processors Supported by the Editions of SQL Server 2000
This table shows the number of processors that the database engine in each
SQL Server 2000 edition can support on symmetric multiprocessing (SMP)
computers.
