The Neoview Windows Client Package has an easy-to-use interface that allows you to install all

of the installation to indicate the versions of installed components.

Neoview SQL Database

Release 2.5 introduces these new features and enhancements to the Neoview SQL database:

• Persistent sample tables (UPDATE STATISTICS statement). The compiler uses persistent

sample tables to improve cardinality estimates for cases when estimates from histograms

cannot be considered reliable.

• The REPLICATE command is a new feature that allows a Neoview installation to replicate

a table or an entire schema from one Neoview system to another. When an entire schema is

replicated, all the tables and dependent objects including indexes, views, privileges, and

statistics are replicated as well. The REPLICATE command behaves like any other SQL

command in that it can be issued anywhere an SQL command could be issued. One useful

capability of this feature is the ability to replicate a table such that the target table has a

different number of partitions from the source table. User-configurable options are supported
