查询多值列

Question

我有一个多值列MISC_CONTENT，该列中包含以下字符串：

amount = 7995 ;channel = SXXXN21 ;group_header = NPS099 ;currency = EUR

如何通过使用group_header进行查找来检索值NPS099？

Answer 1

我们可以尝试使用REGEXP_SUBSTR：

WITH yourTable AS (
    SELECT 'amount = 7995 ;channel = SXXXN21 ;group_header = NPS099 ;currency = EUR' AS col FROM dual
)

SELECT
    REGEXP_SUBSTR(col, '(^|\s|;)group_header = (.*?)\s*(;|$)', 1,1,NULL,2)
FROM yourTable;
