我在此一栏有数据。

Test 20019-2000 test
Test 119 test
Test 19-EM
Test EM - 19

缩略语 但是,我的要求是,它应该把象征性的扼杀从“19”开始的row起。

它只应指第3和第4行。 请就此帮助我。

提前感谢。

问题回答

Oracle regexp does not support the traditional word boundry operators  or <. But you can simulate this by matching the start of string OR a non-word character immediately before the 19.

E.g. 我在此将一字界定为字母数字序列。 因此,你需要

REGEXP_LIKE( mesage,  (A|W)19  )

19,fred 19,fred.19,但fred19/code>。 如果你确实想把一字定义为非白色空间,因此与<条码>fred.19<>/code>不一致。 改动

REGEXP_LIKE( mesage,  (A|s)19  )
