DB2版本的SQL差异 [英] SQL differences for DB2 versions

问题描述

我们正在开发生成和执行 SQL 查询Oracle和 SQL 服务器的软件，使用 ODBC驱动程序。我们正在研究扩展到 DB2 的可能性，但是我读到有几个版本可用。 DB2 for LUW ，对于 iSeries 和z / OS 。

在 SQL 中有 SQL / PLSQL 这些版本的功能？

作为ISV，是否可以为 iSeries获取 DB2 的开发环境或 z / OS

解决方案

许多其他答案已经说过，DB2系列的成员之间存在差异。所有DB2都是SQL-99投诉，每个成员都具有以下 SQL标准（2003）的特定功能，2006,2008,2011）。此外，还为每个成员添加了一些额外的功能，例如LUW中的自治事务或模块。

IBM中有一个名为SQL语言委员会（SLC）的组，其目的是讨论DB2系列的兼容性。 SQL建筑师（Serge Rielau和Rick Swagerman）撰写的以下文章谈到：

• 更多的家庭事务：为便携式DB2应用程序的开发人员选择常用的SQL功能


• 家庭事务：SQL参考跨平台开发

此组创建一个名为

另外，最近一系列的developerWorks中的文章讲述了每个成员的功能家庭。这为您提供了DB2之间的可移植性：

• 为便携式DB2应用程序开发人员选择的常用SQL功能


• 可移植DB2应用程序开发人员的选定常用SQL功能（上一页v4）

We are developing software that generates and executes SQL queries for Oracle and SQL Server using ODBC drivers. We are researching the possibility to expand to DB2, but I read that there are several versions available. DB2 for LUW, for iSeries and for z/OS.

Are there any differences in SQL of SQL/PLSQL functionality in these versions?

As a ISV, is it possible to get a development environment for DB2 for iSeries or z/OS

解决方案

As many other answers already say, there are differences between the members of the DB2 family. All DB2 are SQL-99 complaint, and each member has specific features of the following SQL standards (2003, 2006, 2008, 2011). Also, some extra features have been added to each member, for example autonomous transaction or modules in LUW.

There is a group in IBM called SQL Language Council (SLC) and its purpose is to discuss about the DB2 family compatibility. The following articles written by the SQL architects (Serge Rielau and Rick Swagerman) talk about that:

• More family matters: Selected common SQL features for developers of portable DB2 applications
• Family matters: The SQL Reference for Cross-Platform Development

This group creates a document called SQL Reference for Cross-Platform Development that describe the compatibility between members of the family. The current version is 4.0, and it groups the features of the current DB2 versions.

Also, a recent series of articles in DeveloperWorks talk about the features in each member of the family. That gives you the portability between DB2:

• Selected common SQL features for developers of portable DB2 applications
• Selected common SQL features for developers of portable DB2 applications (Previous v4)
