为 SSIS 派生列组合多个替换表达式答案

【问题标题】：Combine multiple Replace expressions for a SSIS Derived Column为 SSIS 派生列组合多个替换表达式
【发布时间】：2017-10-31 19:50:08
【问题描述】：

我有 3 个在 SSIS 派生列中解析的替换表达式。当我尝试将它们组合成 1 个字符串时，它们会出错。替换都在同一列中。下面是 3 个已解析的表达式。

    REPLACE([Column1],"&#58;",":")

    REPLACE([Column1],"\n"," ")

    REPLACE([Column1],"</div>"," ")

以下是我尝试过的两个未解决的表达式。

    REPLACE([Column1],"&#58;",":","\n"," ","</div>"," ")

    Replace(Replace([Column1],"&#58;",":"),"\n"," "),"</div>"," ")

非常感谢您在获得正确语法方面的任何帮助。

这会将您的 [Column1] 替换为您的所有值。

REPLACE(REPLACE(REPLACE([nightrate],"&#58;",":"),"\n"," "),"</div>"," ")

【解决方案2】：

检查一下。

\ 是转义字符。如果您想在 SSIS 字符串中包含单个反斜杠文字，则必须对其进行转义并使用 \\

代码：

REPLACE(REPLACE(REPLACE([Column1],"</div>",":"),"&#58;",":"),"\\n"," ")

在您的代码中，您错过了第三个替换功能。
