1.在Linux平台上使用disql工具创建List分区表sales时对分区键指定英文字符时,当指定多个值时可以创建成功 SQL> CREATE TABLE sales 2 ( 3 sales_id INT, 4 saleman CHAR(20), 5 saledate DATETIME, 6 city CHAR(10) 7 ) 8 PARTITION BY LIST(city) 9 ( 10 PARTITION p1 VALUES ('a','b'), 11 PARTITION p2 VALUES ('c','d','e'), 12 PARTITION p3 VALUES ('f','g'), 13 PARTITION p4 VALUES ('h','i') 14 ); warning: List partition not include default,partition may be not located executed successfully used time: 115.412(ms). Execute id is 2094. 2.在Linux平台上使用disql工具创建List分区表sales时对分区键指定中文时,当指定多个列表值时创建报错 SQL> drop table sales; executed successfully used time: 307.935(ms). Execute id is 2095. SQL> CREATE TABLE sales 2 ( 3 sales_id INT, 4 saleman CHAR(20), 5 saledate DATETIME, 6 city CHAR(50) 7 ) 8 PARTITION BY LIST(city) 9 ( 10 PARTITION p1 VALUES ('北京','天津'), 11 PARTITION p2 VALUES ('上海','南京','杭州'), 12 PARTITION p3 VALUES ('武汉','长沙'), 13 PARTITION p4 VALUES ('广州','深圳') 14 ); CREATE TABLE sales ( sales_id INT, saleman CHAR(20), saledate DATETIME, city CHAR(50) ) PARTITION BY LIST(city) ( PARTITION p1 VALUES ('北京','天津'), PARTITION p2 VALUES ('上海','南京','杭州'), PARTITION p3 VALUES ('武汉','长沙'), PARTITION p4 VALUES ('广州','深圳') ); PARTITION p2 VALUES ('上海','南京','杭州'), * line 11, column 30, nearby [藝娴穄 has error[-2007]: Syntax error. used time: 0.328(ms). Execute id is 0. 3.在Linux平台上使用disql工具创建List分区表sales时对分区键指定中文时,当指定一个列表值时创建成功 SQL> CREATE TABLE sales 2 ( 3 sales_id INT, 4 saleman CHAR(20), 5 saledate DATETIME, 6 city CHAR(10) 7 ) 8 PARTITION BY LIST(city) 9 ( 10 PARTITION p1 VALUES ('北京'), 11 PARTITION p2 VALUES ('上海'), 12 PARTITION p3 VALUES ('武汉'), 13 PARTITION p4 VALUES ('广州') 14 ); warning: List partition not include default,partition may be not located executed successfully used time: 19.809(ms). Execute id is 2096. 4.在win平台使用disql工具创建List分区表sales时对分区键指定中文时,当指定多个列表值时创建成功 disql V7.1.6.48-Build(2018.03.01-89507)ENT SQL> conn jy/abcd@10.10.10.1:5236 服务器[10.10.10.1:5236]:处于普通打开状态 登录使用时间: 14.001(毫秒) SQL> drop table sales; 操作已执行 已用时间: 352.729(毫秒). 执行号:2118. SQL> CREATE TABLE SALES( 2 SALES_ID INT, 3 SALEMAN CHAR(20), 4 SALEDATE DATETIME, 5 CITY CHAR(10) 6 ) 7 PARTITION BY LIST(CITY) 8 SUBPARTITION BY RANGE(SALEDATE) SUBPARTITION TEMPLATE( 9 SUBPARTITION P11 VALUES LESS THAN ('2012-04-01'), 10 SUBPARTITION P12 VALUES LESS THAN ('2012-07-01'), 11 SUBPARTITION P13 VALUES LESS THAN ('2012-10-01'), 12 SUBPARTITION P14 VALUES EQU OR LESS THAN (MAXVALUE)) 13 ( 14 PARTITION P1 VALUES ('北京','天津') 15 ( 16 SUBPARTITION P11_1 VALUES LESS THAN ('2012-10-01'), 17 SUBPARTITION P11_2 VALUES EQU OR LESS THAN (MAXVALUE) 18 ), 19 PARTITION P2 VALUES ('上海','南京','杭州'), 20 PARTITION P3 VALUES (DEFAULT) 21 ); 操作已执行 已用时间: 26.710(毫秒). 执行号:2119. SQL>
5.在Linux平台上使用管理工具创建List分区表sales时对分区键指定中文时,当指定多个列表值时创建也能成功
6.查看操作系统字符集为UTF-8
[root@shard1 /]# locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
7.修改操作系统字符集
[root@shard1 /]# vi /etc/locale.conf
#LANG="en_US.UTF-8"
LANG="zh_CN.gb2312"
[root@shard1 ~]# locale
LANG=zh_CN.gb2312
LC_CTYPE="zh_CN.gb2312"
LC_NUMERIC="zh_CN.gb2312"
LC_TIME="zh_CN.gb2312"
LC_COLLATE="zh_CN.gb2312"
LC_MONETARY="zh_CN.gb2312"
LC_MESSAGES="zh_CN.gb2312"
LC_PAPER="zh_CN.gb2312"
LC_NAME="zh_CN.gb2312"
LC_ADDRESS="zh_CN.gb2312"
LC_TELEPHONE="zh_CN.gb2312"
LC_MEASUREMENT="zh_CN.gb2312"
LC_IDENTIFICATION="zh_CN.gb2312"
LC_ALL=
8.当修改字符集后在Linux平台使用disql工具创建List分区表sales时对分区键指定中文时,当指定多个列表值时创建成功
[dmdba@shard1 bin]$ ./disql jy/abcd@10.10.10.1:5236
Server[10.10.10.1:5236]:mode is normal, state is open
login used time: 9.677(ms)
disql V7.1.6.46-Build(2018.02.08-89107)ENT
Connected to: DM 7.1.6.46
SQL> drop table sales;
executed successfully
used time: 351.233(ms). Execute id is 2120.
SQL> CREATE TABLE SALES(
2 SALES_ID INT,
3 SALEMAN CHAR(20),
4 SALEDATE DATETIME,
5 CITY CHAR(10)
6 )
7 PARTITION BY LIST(CITY)
8 SUBPARTITION BY RANGE(SALEDATE) SUBPARTITION TEMPLATE(
9 SUBPARTITION P11 VALUES LESS THAN ('2012-04-01'),
10 SUBPARTITION P12 VALUES LESS THAN ('2012-07-01'),
11 SUBPARTITION P13 VALUES LESS THAN ('2012-10-01'),
12 SUBPARTITION P14 VALUES EQU OR LESS THAN (MAXVALUE))
13 (
14 PARTITION P1 VALUES ('北京','天津')
15 (
16 SUBPARTITION P11_1 VALUES LESS THAN ('2012-10-01'),
17 SUBPARTITION P11_2 VALUES EQU OR LESS THAN (MAXVALUE)
18 ),
19 PARTITION P2 VALUES ('上海','南京','杭州'),
20 PARTITION P3 VALUES (DEFAULT)
21 );
executed successfully
used time: 22.411(ms). Execute id is 2121.
从上面的测试来看,字符集对List分区表使用中文存在影响。
