如何从sql语句中选择准确的值

Question

I have multiple records that start with "She" like "shepherd", "shell", "shelf"... I want to return records that has "she" with

SELECT records FROM MYTABLE WHERE records = 'She'

However this returns all data mentioned above... how can I return just "she' without the rest of the data?

Answer 1

如果您想获取带有“She”的单词的记录，则查询应为：

SELECT records FROM MYTABLE WHERE records LIKE 'She %'

Answer 2

To just select the ones that start with "she" (will also select records that start with "shephard" etc):

  SELECT records FROM MYTABLE WHERE records LIKE 'she%'

The ones that have the word "she" in it:

  SELECT records FROM MYTABLE 
      WHERE records LIKE 'she %' OR 
            records LIKE '% she %' OR 
            records LIKE '% she'

You could perhaps use regular expressions as well.
