mysql 字符编码的查看与修改

修改数据库字符集:

  代码如下:

  ALTER DATABASE db_name DEFAULT CHARACTER SET character_name [COLLATE ...];  


把表默认的字符集和所有字符列(CHAR,VARCHAR,TEXT)改为新的字符集:

  代码如下:

  ALTER TABLE tbl_name CONVERT TO CHARACTER SET character_name [COLLATE ...] 


  如:ALTER TABLE logtest CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci; 

只是修改表的默认字符集:

  代码如下:

  ALTER TABLE tbl_name DEFAULT CHARACTER SET character_name [COLLATE...]; 


  如:ALTER TABLE logtest DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; 

修改字段的字符集:

  代码如下:

  ALTER TABLE tbl_name CHANGE c_name c_name CHARACTER SET character_name [COLLATE ...]; 


  如:ALTER TABLE logtest CHANGE title title VARCHAR(100) CHARACTER SET utf8 COLLATE utf8_general_ci; 

查看数据库编码:

  代码如下:

  SHOW CREATE DATABASE db_name;  


查看表编码:

  代码如下:

  SHOW CREATE TABLE tbl_name;  


查看字段编码:

  代码如下:


  SHOW FULL COLUMNS FROM tbl_name;
