如果需要修改mysql字段的順序，應(yīng)該怎么做呢？下面就將為您介紹修改mysql字段順序的方法，原表結(jié)構(gòu)如下：

CREATE TABLE `tb_area_collect_school_week` (                         
                               `id` char(36) NOT NULL,                                            
                               `date_entered` varchar(20) NOT NULL,                               
                               `date_modified` datetime NOT NULL,                                 
                               `assigned_user_id` char(36) default NULL,                          
                               `modified_user_id` char(36) default NULL,                          
                               `created_by` char(36) default NULL,                                
                               `name` varchar(50) NOT NULL,                                       
                               `description` mediumtext,                                          
                               `deleted` tinyint(1) NOT NULL default '0',                         
                               `qy_id` int(10) unsigned NOT NULL auto_increment COMMENT '序號(hào)',   
                               `provinces` varchar(50) default NULL COMMENT '省份',               
                               `city` varchar(50) NOT NULL COMMENT '地市',                                                       
                               `school_open_up` int(20) NOT NULL COMMENT '開(kāi)通學(xué)校數(shù)',            
                               `school_cover_percent` varchar(50) NOT NULL COMMENT '覆蓋率',      
                               `school_count` int(20) NOT NULL COMMENT '學(xué)?？倲?shù)',   
                               `area` varchar(50) default NULL,                 
                               `date` varchar(10) NOT NULL COMMENT '日期',                        
                               `system` varchar(10) default NULL COMMENT '系統(tǒng)',                  
                               PRIMARY KEY USING BTREE (`id`,`qy_id`),                           
                               KEY `provinces` USING BTREE (`provinces`),                         
                               KEY `city` USING BTREE (`city`),                                   
                               KEY `area` USING BTREE (`area`),                                   
                               KEY `date` USING BTREE (`date`),                                   
                               KEY `SYSTEM` (`system`)                                            
                             ) ENGINE=MyISAM DEFAULT CHARSET=gbk  

原來(lái)表結(jié)構(gòu)是這樣，現(xiàn)在要表結(jié)構(gòu)變成

CREATE TABLE `tb_area_collect_school_week` (                          
                               `id` char(36) NOT NULL,                                             
                               `date_entered` varchar(20) NOT NULL,                                
                               `date_modified` datetime NOT NULL,                                  
                               `assigned_user_id` char(36) default NULL,                           
                               `modified_user_id` char(36) default NULL,                           
                               `created_by` char(36) default NULL,                                 
                               `name` varchar(50) NOT NULL,                                        
                               `description` mediumtext,                                           
                               `deleted` tinyint(1) NOT NULL default '0',                          
                               `qy_id` int(10) unsigned NOT NULL auto_increment COMMENT '序號(hào)',   
                               `provinces` varchar(50) default NULL COMMENT '省份',                
                               `city` varchar(50) NOT NULL COMMENT '地市',                         
                               `area` varchar(50) default NULL,                                    
                               `school_open_up` int(20) NOT NULL COMMENT '開(kāi)通學(xué)校數(shù)',             
                               `school_cover_percent` varchar(50) NOT NULL COMMENT '覆蓋率',       
                               `school_count` int(20) NOT NULL COMMENT '學(xué)?？倲?shù)',                 
                               `date` varchar(10) NOT NULL COMMENT '日期',                         
                               `system` varchar(10) default NULL COMMENT '系統(tǒng)',                   
                               PRIMARY KEY USING BTREE (`id`,`qy_id`),                            
                               KEY `provinces` USING BTREE (`provinces`),                          
                               KEY `city` USING BTREE (`city`),                                    
                               KEY `area` USING BTREE (`area`),                                    
                               KEY `date` USING BTREE (`date`),                                    
                               KEY `SYSTEM` (`system`)                                             
                             ) ENGINE=MyISAM DEFAULT CHARSET=gbk
