MySQL汉字转拼音方案

1.创建表

-- sys.pinyintable definition
CREATE TABLE `pinyintable` (
  `id` int NOT NULL,
  `pin_yin` varchar(255) DEFAULT NULL,
  `code` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

3.创建函数

Create Function sys.to_pinyin (NAME VARCHAR(255) CharSet gbk) RETURNS Varchar(255) CHARSet gbk
Begin
  Declare mycode INT ; 
  Declare tmp_lcode Varchar(2) CHARSet gbk ;
  Declare lcode INT ; 
  Declare tmp_rcode Varchar(2) CHARSet gbk ;
  Declare rcode INT ; 
  Declare mypy Varchar(255) CHARSet gbk DEFAULT '' ; 
  Declare lp INT ;
 
  Set mycode = 0 ;
  Set lp = 1 ;
  Set NAME = HEX(NAME) ;
 
  While lp < LENGTH(NAME) DO
    Set tmp_lcode = SUBSTRING(NAME, lp, 2) ;
    Set lcode = CAST(ASCII(UNHEX(tmp_lcode)) AS UNSIGNED) ;
    Set tmp_rcode = SUBSTRING(NAME, lp + 2, 2) ;
    Set rcode = CAST(ASCII(UNHEX(tmp_rcode)) AS UNSIGNED) ;
 
    IF lcode > 128 THEN
      Set mycode = 65536 - lcode * 256 - rcode ; 
      Select CONCAT(mypy, pin_yin) Into mypy From sys.pinyintable Where code >= Abs(mycode) Order By code Asc Limit 1;
      Set lp = lp + 4 ;
    Else
      Set mypy = Concat(mypy,Char(Cast(Ascii(UNHEX(SUBSTRING(NAME, lp, 2))) AS UNSIGNED)));
      Set lp = lp + 2 ;
    End If;
  End While;
  Return Lower(mypy) ;
End;

Select sys.to_pinyin("中国") From Dual;
