在MySQL中将列值与单独的文本连接起来并显示在单个列中
让我们首先创建一个表-
mysql> create table DemoTable-> (
-> Id int,
-> Name varchar(20)
-> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values(101,'Chris');mysql> insert into DemoTable values(102,'David');
mysql> insert into DemoTable values(103,'Robert');
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
+------+--------+| Id | Name |
+------+--------+
| 101 | Chris |
| 102 | David |
| 103 | Robert |
+------+--------+
3 rows in set (0.00 sec)
以下是MySQL查询，以使用单独的文本连接列值-
mysql> select concat('The student id and name is= ', Id , ',' , Name, ' .') from DemoTable;这将产生以下输出-
+---------------------------------------------------------------+| concat('The student id and name is= ', Id , ',' , Name, ' .') |
+---------------------------------------------------------------+
| The student id and name is= 101,Chris . |
| The student id and name is= 102,David . |
| The student id and name is= 103,Robert . |
+---------------------------------------------------------------+
3 rows in set (0.01 sec)
