我在Oracle表-table1的一个单元格中有此字符串

我需要在下表中对此进行细分：

基本上，我需要扫描OBR并中断消息，但始终在消息前添加MSH和PID。

有人可以帮助使用Oracle SQL进行编码吗？

Oracle设置：

FROM   DUAL;

查询：

SELECT REGEXP_SUBSTR( t.value, '^MSH.*?' || CHR(10) || 'PID.*?' || CHR(10) )
         || REGEXP_SUBSTR( t.value, 'OBR.*?' || CHR(10) || '((OBX|FT1).*?($|' || CHR(10) || '))*', 1, c.COLUMN_VALUE ) AS split_value

       TABLE(

输出：
