我们使用客户端9使用SAP BO 3.1 SP5 for DB2 9.7创建了一个报告。现在我们已将DB2从9.7升级到10.5。因此，使用客户端10 z / OS，我们已连接SAP BO，但生成的查询与我们在连接客户端9时获得的查询不同。任何人都可以解释此问题吗？
是否无法将DB10.5与客户端10 z / OS连接？生成的查询是否因此版本差异而有差异？
对不起伙计们，我是BO的新手。也许这是一个愚蠢的问题，但我们必须回答这个问题。
提前致谢。
我已附上以下生成的查询：

差异代替LEFT JOIN，RIGHT JOIN已在客户端10 z / OS中添加，并且在客户端10 z / OS中添加了附加条件SURVEY.CREATED_BY = SURVEY.IS_CREATED。
