在sql查询中找到像这样的单词

Question

我有一个这样的字符串：

i would like to go to office, and i would like to go to market

我的问题是：字符串like出现多少次？

请写一个查询。

Answer 1

您可以使用regexp_count：

SELECT REGEXP_COUNT('i like to go , and i would like market', 'like')
FROM   DUAL;

Answer 2

单词“like”在您发布的字符串中出现两次。

以下是查询：

SELECT *
  FROM SOME_TABLE
  WHERE SOME_VALUE = SOME_OTHER_VALUE
