String_split function is not splitting delimiters in SQL Server 2019

问题

I am trying to split the values in LOB column, while keeping the first column intact using the script below

select * 
from [dbo].[ReqApp]
where lob in 
 (select value from string_split ('Staff;Wealth Management',';'))

The query returns this:

The desire outcome is this.

I am using SQL Server 2019. Please provide suggestions on how to modify my script to get the desired outcome.

回答1:

I think you want apply:

select ra.id, s.value as lob
from [dbo].[ReqApp] ra cross apply
     string_split(ra.lob, ';') s;

This produces the data you have. Your query though has a where, suggesting that you want filtering.

Try using cross apply

SELECT id, value as lob 
FROM [dbo].[ReqApp]  
CROSS APPLY STRING_SPLIT(lob, ',');
