Checking Character Set Setting

This section describes how to check the character set settings of text column in MySQL server.

After created my test table, I used the following SQL Monitor commands to check what character sets are defined for each text column in the table:

C:\>\local\mysql\bin\mysql -u herong -pTopSecret

mysql> USE HerongDB;
Database changed

mysql> SHOW CREATE DATABASE HerongDB;
+----------+-------------------------------------------
| Database | Create Database
+----------+-------------------------------------------
| herongdb | CREATE DATABASE `herongdb` 
   /*!40100 DEFAULT CHARACTER SET latin1 */
+----------+-------------------------------------------

mysql> SHOW CREATE TABLE Comment_Mixed;
+---------------+--------------------------------------
| Table         | Create Table
+---------------+----------------------------------------------
| Comment_Mixed | CREATE TABLE `comment_mixed` (
  `Test_Name` varchar(256) default NULL,
  `String_ASCII` varchar(256) character set ascii default NULL,
  `String_Latin1` varchar(256) default NULL,
  `String_UTF8` varchar(256) character set utf8 default NULL,
  `String_GBK` varchar(256) character set gbk default NULL,
  `String_Big5` varchar(256) character set big5 default NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1 |
+---------------+----------------------------------------------

Here is what I learned from the output:
