Answer 1

您需要查找如何转义字符，即使用两个单引号而不是一个''girl'',''playing''

Answer 2

You can escape single quotes with two single quotes: for example:

... where lastname='O''Malley'

in your case:

''girl'',''playing''

Answer 3

Since MySQL recognizes both single and double quotes as string delimiters, one option is to use double quotes when you want to include single quotes in the value, or vice versa.

call YourProc("'girl', 'playing'");

The alternative is to escape the quotes with backslash:

call YourProc('\'girl\', \'playing\'');
