使用 SQL 从字符串中提取 ID

Question

我想通过 SQL（无 T-SQL）

从以下字符串中提取 ID

XY_FOO_BAR1=123;XY_FOO_BAR2=456;XY_FOO_BAR3=789;

结果应如下所示：

123
456
789

使用 T-SQL 会很容易，但是我怎样才能解决纯 SQL 的问题呢？我已经用 PATINDEX、CHARINDEX 和 SUBSTRING 尝试了一些东西，但不幸的是，这很复杂，当然更容易实现。

如有任何提示，我将不胜感激。

最终解决方案感谢@mtdot:

with List as (
    select v.value as keyValue
      from xy.foo cross apply STRING_SPLIT(stay_val,';') as v
     where id = 987654321 
)
select (select value from STRING_SPLIT(KeyValue, '=') order by value desc offset 1 rows fetch next 1 rows only) as Ids from List

Answer 1

试过这个似乎没问题。但是 order by value 似乎很棘手

declare @Raw nvarchar(max) = 'XY_FOO_BAR1=123;XY_FOO_BAR2=456;XY_FOO_BAR3=789;';
with List as (
    select value as KeyValue from STRING_SPLIT(@Raw, ';') where value != ''
)
select (select value from STRING_SPLIT(KeyValue, '=') order by value desc offset 1 rows fetch next 1 rows only) as Ids from List

Answer 2

希望这会有所帮助

=======

 declare @a varchar(100);
set @a = 'XY_FOO_BAR1=123;XY_FOO_BAR2=456;XY_FOO_BAR3=789;';
;with split1(whole) as
(
    select value from string_split(@a,';') where value <> ''
)
SELECT (select value from String_split(whole, '=') order by value desc offset 1 rows)  FROM  split1
