SSIS-額外派生列

Question

如何在SSIS包中轉換下面的SQL代碼，因為我試圖在Extra Derived Column中使用相同的SQL代碼，但是在這里我遇到了錯誤。

SQL代碼：

REVERSE(SUBSTRING(REVERSE ([MeasureName]),PATINDEX('% %',REVERSE ([MeasureName])),50))

Please suggest me

Error Msg:

------------------------------

好的，在SSIS中，SSIS中沒有PATINDEX ，您需要使用FINDSTRING` ：

FINDSTRING(character_expression, searchstring, occurrence)

返回字符表達式中指定出現的字符串的位置

這不會引發錯誤，但可能不是您想要的，因為我不知道您如何嘗試使用字符串來實現：

REVERSE(SUBSTRING(REVERSE([Company]),FINDSTRING("% %",REVERSE([Company]),1),50))
