[英]ssis case statement derived column
still learning about SSIS还在学习 SSIS
I have an excel source in SSIS, I need to create a case statement based on one of the columns [Teacher]
我在 SSIS 中有一个 excel 源,我需要根据其中一列[Teacher]
创建一个案例语句
but as a derived column (as it does not work in the SQL statement)但作为派生列(因为它在 SQL 语句中不起作用)
the normal SQL would be正常的 SQL 将是
CASE WHEN [Teacher] like '%A%' then [Teacher] else null end as [Teacher]
I have tried to look for examples, but can't find any with use of the like '%A%'我试图寻找示例,但找不到任何使用“%A%”之类的示例
please help请帮忙
You should use conditional with FINDSTRING() function as following (assuming that [Teacher]
column is of type DT_WSTR
) :您应该使用FINDSTRING() function 条件如下(假设[Teacher]
列的类型为DT_WSTR
) :
FINDSTRING([Teacher],"A",1) > 0 ? [Teacher] : NULL(DT_WSTR,50)
