SQLMagic
Managing HP NonStop™ SQL/MP databases can prove to be complicated, time-consuming and
costly. In a time when effective use of technical resources is critical, businesses need a solution
that simplifies the management of HP NonStop SQL/MP databases.

Increase Productivity
From increased system responsiveness, to
more effective use of technical resources,
SQLMagic is designed to deliver speed,
accuracy and efficiency at every turn. With
SQLMagic, users can quickly create, alter or
drop SQL objects, such as tables, views and
indexes. And with SQLMagic’s powerful
set of wizards, complex tasks like splitting
partitions, moving tables or creating new
databases are made easy.
SQLMagic can generate data definition language
(DDL) statements that describe SQL objects,
such as tables, views or indexes. For tables, it can
also generate the Enscribe DDL definition.
SQLMagic can generate scripts to perform SQL
operations in batch mode. This is useful for
long-running or resource-intensive operations
Simplify Table Maintenance
and Management
SQLMagic allows users to browse SQL tables
and insert, update or delete rows. Rows can be
displayed in the order determined by the primary
key or any of the table’s indexes. Users can also
restrict which rows are displayed by specifying
a filter expression, which is especially useful for
large tables.
For further functionality, an import data wizard
allows data to be imported into a table from
a PC file or an HP NonStop file. SQLMagic
supports comma-separated values (CSV) files
and Open Database Connectivity (ODBC)
data sources. In addition, an export data wizard
allows data to be exported from a table or view
to a file or ODBC data source.
Build Queries Quickly and Easily
The visual query builder in SQLMagic allows
users to design queries via a graphical interface,
eliminating the need to type long SQL
statements. Even the most complex queries can
be built in just a few minutes.
Query performance can be fine-tuned using
query and table property sheets to set
Control parameter values. An “explain plan”
feature provides easy access to details of the
query execution plan. Queries can be run online
or in the background. Once a query has been
built and tested, it can be stored in a database
for future use.
The SQLView™ program provides a simple way
to read data from a nonstop SQL database.
Users can display, print and export data from
queries built using the visual query builder
as well as directly from tables and views. No
knowledge of SQL is required to use SQLView.
SQL Statistics
The SQL compiler uses statistics stored in the
catalog to select a strategy for an execution plan.
Users can copy statistics from one table (or
index) to another, making it possible to test the
execution of SQL statements on a test database
using production database statistics.

SQLMagic maintains multiple versions of

to compare plans with previous versions to
quickly identify any increase in execution costs.
In addition, a number of execution plan reports
are available. These include the following:
high-cost statements
scans that examine a high percentage
of rows
statements that use a sort
statements that use parallel execution
statements that use a specified join strategy
statements that use a specified access type,
