从报告

Question

我在表statu中有一个名为TB_ORDERS的字段。

如果字段状态具有数值，我应该从报告中排除该记录 - 仅应按字母顺序显示。

我该怎么做？

我应该从报告中排除该记录 - 只应显示字母。

您可以在过滤谓词中使用 REGEXP_LIKE 。

• NOT REGEXP_LIKE(status, '[[:digit:]]+')

或者，

• NOT REGEXP_LIKE(status, '\d+')

或者，

• NOT REGEXP_LIKE(status, '[0-9]+')

例如，

SELECT * FROM TB_ORDERS
WHERE NOT REGEXP_LIKE(status, '[[:digit:]]+');

SQL> WITH TB_ORDERS AS(
  2  SELECT 'abc123abc' status FROM dual UNION ALL
  3  SELECT 'abcabc' status FROM dual UNION ALL
  4  SELECT 'abcabc123' status FROM dual UNION ALL
  5  SELECT '123abcabc123' status FROM dual
  6  )
  7  SELECT * FROM TB_ORDERS
  8  WHERE NOT REGEXP_LIKE(status, '[[:digit:]]+');
