如何与LIKE运算符一起使用MySQL SOUNDEX()函数从表中检索记录？
我们知道该SOUNDEX()函数用于返回soundex，这是一种语音算法，用于在声音的英语发音（一个字符串或一个字符串）后索引名称。在以下示例中，我们从“student_info”表中获取数据，并使用SOUNDEX()LIKE运算符应用函数以从表中检索特定记录-
mysql> Select * from Student_info; +------+---------+------------+------------+ | id | Name | Address | Subject | +------+---------+------------+------------+ | 101 | YashPal | Amritsar | History | | 105 | Gaurav | Chandigarh | Literature | | 125 | Raman | Shimla | Computers | +------+---------+------------+------------+ 3 rows in set (0.00 sec) mysql> Select * from student_info where SOUNDEX(Name) LIKE '%G%'; +------+--------+------------+------------+ | id | Name | Address | Subject | +------+--------+------------+------------+ | 105 | Gaurav | Chandigarh | Literature | +------+--------+------------+------------+ 1 row in set (0.00 sec)
我们将列的名称用作SOUNDEX()函数的参数，并且它返回具有SOUNDEX值LIKE％G％的行。
请记住，SOUNDEX()函数的输出将始终包含作为参数传入的字符串的第一个字母。例如，如果我们将'Ram'作为SOUNDEX()函数的参数传递，然后查看输出，则它包含'R'作为第一个字符-
mysql> Select SOUNDEX('Ram');
+----------------+
| SOUNDEX('Ram') |
+----------------+
| R500 |
+----------------+
1 row in set (0.00 sec)
mysql> Select SOUNDEX('ram');
+----------------+
| SOUNDEX('ram') |
+----------------+
| R500 |
+----------------+
1 row in set (0.00 sec)
