我们如何检查 Oracle 数据库中逗号分隔值的列中是否存在字符串
How can we check whether a string is present or not in column with comma separated values in Oracle db
我被困在这个问题上,找不到解决方案。
我有两列 cus_category
和 cus_flag
。 cus_category
列的值类似于 cus_category
existing,cleared
existing
cleared
expansion,exisitng,cleared
expansion,cleared
former
former,cleared
former,cleared,expansion
former,existing,cleared
等等。我想将 cus_flag
设置为 1,其中 cus_category
的值是扩展且存在,即使它类似于 expansion,exisitng,cleared
并将值 0 设置为已清除和前者。如何实现这一点任何人都可以帮助我。
如果类别既有扩展又有现有,那么,
Update [YourTable]
Set cus_flag= Case when (cus_category like '%expansion%' and cus_category like '%existing%')
then 1 else 0 end
如果类别应该有扩展或现有
Update [YourTable]
Set cus_flag= Case when (cus_category like '%expansion%' or cus_category like '%existing%')
then 1 else 0 end
有 2 个不同的更新
update your_table set cus_flag = 1
where cus_category like '%expansion%' and cus_category like '%exisitng%';
update your_table set cus_flag = 0
where cus_category like '%cleared%' and cus_category like '%former%';
