在MySQL的文本列中搜索字符串？
您可以借助LIKE子句在MySQL的text列中搜索字符串。语法如下-
select *from yourTableName where yourColumnName like '%anyStringValue%';
要使用上述语法，让我们首先创建一个表-
mysql> create table SearchTextDemo −> ( −> BookName TEXT −> );
在表中插入一些字符串。查询如下-
mysql> insert into SearchTextDemo values('Let us C');
mysql> insert into SearchTextDemo values('C in Depth');
mysql> insert into SearchTextDemo values('C in Depth with Data Structure');
mysql> insert into SearchTextDemo values('Introduction to Java');
mysql> insert into SearchTextDemo values('Java in Depth');在select语句的帮助下显示所有记录。查询如下-
mysql> select *from SearchTextDemo;
以下是输出-
+--------------------------------+ | BookName | +--------------------------------+ | Let us C | | C in Depth | | C in Depth with Data Structure | | Introduction to Java | | Java in Depth | +--------------------------------+ 5 rows in set (0.00 sec)
这是在文本列中搜索特定字符串的查询-
mysql> select *from SearchTextDemo where BookName like '%in Depth%';
以下是输出-
+--------------------------------+ | BookName | +--------------------------------+ | C in Depth | | C in Depth with Data Structure | | Java in Depth | +--------------------------------+ 3 rows in set (0.00 sec)
查看上面的示例输出，已从列名称“BookName”中搜索了数据类型为TEXT的字符串“inDepth”。
