MySQL 如何包含带引号的逗号分隔列

首先让我们创建一个-

mysql> create table DemoTable1407
 -> (
 -> Name text
 -> );
Query OK, 0 rows affected (0.51 sec)

使用 insert 向表中插入一些记录-

mysql> insert into DemoTable1407 values('John,Bob');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable1407 values('Carol,David,Adam');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable1407 values('Mike,Sam,Chris');
Query OK, 1 row affected (0.19 sec)

使用 select 显示表中的所有记录-

mysql> select * from DemoTable1407;

这将产生以下输出-

+------------------+
| Name             |
+------------------+
| John,Bob         |
| Carol,David,Adam |
| Mike,Sam,Chris   |
+------------------+
3 rows in set (0.00 sec)

这是一个在MySQL中包含带引号的逗号分隔列的查询-

mysql> select concat("'", replace(Name, ",", "','"), "'") AS IncludingQuotes from DemoTable1407;

这将产生以下输出-

+------------------------+
| IncludingQuotes        |
+------------------------+
| 'John','Bob'           |
| 'Carol','David','Adam' |
| 'Mike','Sam','Chris'   |
+------------------------+
3 rows in set (0.00 sec)
