包含不在mysql中工作

Question

我正在使用CONTAINS，但它在mysql中不起作用。

 mysql> SELECT * FROM MUTHU;
+---------------------+
| MY                  |
+---------------------+
| how is your studies |
| how are you there   |
| hi there            |
+---------------------+
3 rows in set (0.00 sec)

mysql> SELECT * FROM MUTHU CONTAINS ( MY, "how" );
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near '( MY,
 "how" )' at line 1

Answer 1

我不认为MYSQL有一个名为CONTAINS的函数，请尝试以下查询：

SELECT * FROM MUTHU
WHERE MY LIKE '%how%';

Answer 2

您错过了Where条件，

试试这个：

SELECT * FROM MUTHU
Where MY CONTAINS ( MY,"how" );

Answer 3

我认为contains主要用于Xpath / Xquery。 mysql中的类似函数是INSTR（）。正确的代码是使用它：

    select * from MUTHU
    where INSTR(MY, 'how') > 0;
