Sql/Mp Version Management - HP NonStop SQL/MP Programming Manual

Introduction

SQL/MP Version Management

Each product version update (PVU) of NonStop SQL/MP has an associated version
number. The first two PVUs were version 1 (C10 and C20) and version 2 (C30).
Version 300 SQL/MP began using a three-digit version number to allow for software
product revisions (SPRs).
A new version number is always greater than the previous number, but the new
number might not follow a constant increment. For example, consecutive version
numbers after version 340 might be 345, 350, and 360.
In addition, SQL objects (tables, indexes, views, collations, and constraints), programs,
and catalogs have associated version numbers. This version number indicates the
SQL features used by the SQL object or program and the SQL/MP software with which
the SQL object or program is compatible. For example, a version 2 table might use the
date-time data types or allow null values in a column. A version 2 table is compatible
with version 2 and version 315 SQL/MP software, but it is not compatible with version 1
software.
This manual includes this version information:

Using compatible versions of the C compiler, SQL compiler, and SQL executor to
compile and run a program

Using the data status language (DSL) statements: GET VERSION (for SQL
objects, catalogs, and SQL/MP software), GET VERSION OF PROGRAM, and
GET CATALOG OF SYSTEM

Generating different versions of the SQLSA and SQLDA structures

Using run-time SQLSA versioning, which allows a program to use an SQLSA
structure with the same version as the current SQL/MP software for the system
(available with version 340 or later SQL/MP software)

Converting a C program written for version 1 or version 2 SQL/MP software to use
version 300 (or later) SQL features and data structures
For additional information about version issues, see the SQL/MP Version Management
Guide.
