SSIS条件拆分错误，语法相关？

Question

我正在SSIS中创建一个数据流任务，该任务将比较两个表并根据第一个表更新第二个表。 我基本上是在逐字逐句地遵循本指南： https : //www.mssqltips.com/sqlservertip/5082/synchronize-table-data-using-a-merge-join-in-ssis/ 。

我收到以下错误消息，并拆分了第二个条件：

看起来我遇到了一些语法问题，我的直觉是我的列名中带有空格的无法处理。 我无法更改任何一个表中的列名，所以我想知道是否有一种短语表达方式，以便它接受带空格的列名。 在这种情况下最好的行动方案是什么？

Answer 1

您需要在所有带有空格的列名称周围加方括号。

例如，在此位：

(Core Competency Service Provided != [Core Competency Service Provided (1)])

您有[Core Competency Service Provided (1)]周围的产品，却没有提供的Core Competency Service Provided周围的产品
