各种字段的条件分割 - 将数据移动到右侧字段

Question

我试图修复一个表，其中包含已由ETL任务加载的数据。在表的最后6列中，由于在一个字段中找到了多个分隔符，因此有些数据被放置在错误的字段中。所以我试图创建SSIS条件分割和派生列，将它们放回到正确的字段中。

这是表数据的屏幕截图：

我发现FR中的那些地址导致了问题。那么我怎么能：

1. 移动城市字段数据并将其与StreetAddress相结合
2. 将StateProvinceCode数据移至City
3. StateProvinceName to StateProvinceCode
4. CountryCode to StateProvinceName
5. CountryName to CountryCode
6. 最后用分隔符拆分PostCode数据并将逗号前的数据移到CountryName？

Answer 1

You can check following Update script But before running on productive, you can better copy your data as backup

I did not use a SQL split function here but instead used the SQL CharIndex function since your data has a simple structure

update AddressData
set
 StreetAddress = StreetAddress + City
, City = StateProvinceCode
, StateProvinceCode = StateProvinceName
, StateProvinceName = CountryCode
, CountryCode = CountryName
, CountryName = LEFT(PostCode, CHARINDEX(',',PostCode) - 1)
, PostCode = RIGHT(PostCode, LEN(PostCode) - CHARINDEX(',',PostCode) )
where CountryName = 'FR'
