[原創] mysql表欄位多少限定
我們知道在Oracle中一個表上的欄位最多隻能有1000個,那麼在mysql,一個表上能有多少個欄位呢?
今天在PUB上看到一個貼子(http://www.itpub.net/thread-1045069-1-1.html)於是查了下文件,沒有發現相關說明.
測試了一下,發現了一個"奇怪"的數字--2599,不知和版本是否有關係?
測試過程
1.建立一個測試表
mysql> select version();
+-----------------+
| version() |
+-----------------+
| 5.0.26-standard |
+-----------------+
1 row in set (0.00 sec)
mysql> create table t1(id int) ;
Query OK, 0 rows affected (0.02 sec)
mysql> desc t1;
+-------+---------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+---------+------+-----+---------+-------+
| id | int(11) | YES | | NULL | |
+-------+---------+------+-----+---------+-------+
1 row in set (0.00 sec)
2.書寫一個測試指令碼
[root@dbatest1 shell]# cat add_col.sh
#!/bin/sh
x=1
while [ $x -le 3000 ]
do
mysql -uroot -pabc123 -Ddb1 << EOF >> /root/shell/add_col_log.log
alter table t1 add column f$x char(1);
EOF
x=`expr $x + 1`
done
[root@dbatest1 shell]#
3.發現新增到2598是可以成功的.到2599時就失敗了
+ x=2598
+ '[' 2598 -le 3000 ']'
+ mysql -uroot -pabc123 -Ddb1
++ expr 2598 + 1
+ x=2599
+ '[' 2599 -le 3000 ']'
+ mysql -uroot -pabc123 -Ddb1
ERROR 1117 (HY000) at line 1: Too many columns
4.DESC表,確認.最多還是2599列
mysql> desc t1;
+-------+---------+------+-----+---------+-------+

+-------+---------+------+-----+---------+-------+
