实现思路

使用sql来实现 简体转存繁体,

我的大致思路是 把简繁字段对应存储到表中,自己编写函数进行转换 

实现步骤

创建存储表

-- 创建存储表 
drop table if exists t_basic_ct;
create table if not exists t_basic_ct(s_str char(4),c_str char(4),constraint pk_basic_ct primary  key (s_str,c_str))

创建转换函数

drop FUNCTION if exists `f_get_ct`;;
CREATE FUNCTION `f_get_ct`(vi_sstr varchar(255)) RETURNS varchar(255) CHARSET utf8
BEGIN
  declare vn_length int;
    declare vn_start int default 1;
    declare vn_result varchar(255) default '';
    declare vn_str char(1);
    declare vn_tmpstr char(1);
    declare vn_cnt bit(1);
    set vn_length  = char_length(vi_sstr);
    while vn_start <= vn_length do
     set vn_str  = substr(substr(vi_sstr,1,vn_start),-1);
     if ascii(vn_str) < 128 then 
       set vn_result = concat(vn_result,vn_str);
       set vn_start = vn_start + 1;
  else
     select c_str ,count(*) into vn_tmpstr,vn_cnt from t_basic_ct where s_str = vn_str;
     set vn_result = concat(vn_result,coalesce(vn_tmpstr,vn_str));
     set vn_start = vn_start + 1;
  end if;
  end while; 
RETURN vn_result;
END;;

获取数据源

类似如下
