如何在MySQL表中搜索特定字符串?
使用等于运算符进行完全匹配-
select *from yourTableName where yourColumnName=yourValue;
让我们首先创建一个表-
mysql> create table DemoTable-> (
-> FirstName varchar(100),
-> LastName varchar(100)
-> );
mysql> insert into DemoTable values('John','Doe');
mysql> insert into DemoTable values('Chris','Brown');
mysql> insert into DemoTable values('Carol','Taylor');
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
输出结果
这将产生以下输出-
+-----------+----------+| FirstName | LastName |
+-----------+----------+
| John | Smith |
| John | Doe |
| Chris | Brown |
| Carol | Taylor |
+-----------+----------+
4 rows in set (0.00 sec)
以下是在MySQL表中搜索特定字符串的查询-
mysql> select *from DemoTable where LastName='Doe';
输出结果
这将产生以下输出-
+-----------+----------+| FirstName | LastName |
+-----------+----------+
| John | Doe |
+-----------+----------+
1 row in set (0.00 sec)
