为此,请使用REGEXP并获取以特定编号开头的记录。以下是语法:
Select yourColumnName1,yourColumnName2 from yourTableName where yourColumnName2 REGEXP '^yourStringValue[yourNumericValue]';
让我们创建一个表-
mysql> create table demo45 -> ( −> id int not null auto_increment primary key, −> value varchar(50) −> );
借助insert命令将一些记录插入表中。我们将插入包含字符串和数字(例如“ John500,“ John6500””等)的记录-
mysql> insert into demo45(value) values('John500'); mysql> insert into demo45(value) values('John1500'); mysql> insert into demo45(value) values('John5500'); mysql> insert into demo45(value) values('John6500'); mysql> insert into demo45(value) values('John8600');
使用select语句显示表中的记录-
mysql> select *from demo45;
这将产生以下输出-
+----+----------+ | id | value | +----+----------+ | 1 | John500 | | 2 | John1500 | | 3 | John5500 | | 4 | John6500 | | 5 | John8600 | +----+----------+ 5 rows in set (0.00 sec)
以下是查询以获取具有特定编号的记录,即此处的5和6-
mysql> select id,value −> from demo45 −> where value REGEXP '^John[56]';
这将产生以下输出-
+----+----------+ | id | value | +----+----------+ | 1 | John500 | | 3 | John5500 | | 4 | John6500 | +----+----------+ 3 rows in set (0.00 sec)
