MySQL實現漢字轉拼音，趕快一起學起來

發布時間：2023-07-02 23:26:48 作者：網友整理

今天接到一個新的業務需求，客戶需要將指定的中文漢字轉換成拼音（含：簡拼、首全拼、尾全拼）。

1. 創建基礎數據表

-- ----------------------------

-- Table structure for bst_wbjq

-- ----------------------------

DROP TABLE IF EXISTS `bst_wbjq`;

CREATE TABLE `bst_wbjq` (

`CHARACTOR` varchar(200) NOT NULL,

`word` varchar(100) NOT NULL,

`CODE` varchar(100) DEFAULT NULL,

`STROKE` varchar(200) DEFAULT NULL

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

 

-- ----------------------------

-- Table structure for tbl_pinyin

-- ----------------------------

DROP TABLE IF EXISTS `tbl_pinyin`;

CREATE TABLE `tbl_pinyin` (

`SN` bigint(20) NOT NULL,

`WORD` varchar(200) NOT NULL,

`PY` varchar(200) NOT NULL,

`PYLEVEL` int(11) DEFAULT NULL

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. 插入基礎數據記錄

-- ----------------------------

-- Records of bst_wbjq

-- ----------------------------

truncate table bst_wbjq;

INSERT INTO `bst_wbjq` VALUES ('禪', 'C', 'P', '^K');

INSERT INTO `bst_wbjq` VALUES ('訝', 'Y', 'Y', '2T');

INSERT INTO `bst_wbjq` VALUES ('焉', 'Y', 'G', 'Pa');

INSERT INTO `bst_wbjq` VALUES ('閹', 'Y', 'U', 'V2');

INSERT INTO `bst_wbjq` VALUES ('煙', 'Y', 'O', 'Ng');

INSERT INTO `bst_wbjq` VALUES ('淹', 'Y', 'I', 'V^');

INSERT INTO `bst_wbjq` VALUES ('圊', 'Q', 'L', 'Rz');

INSERT INTO `bst_wbjq` VALUES ('圉', 'Y', 'L', 'S?');

INSERT INTO `bst_wbjq` VALUES ('帔', 'P', 'M', ';~');

.... ....

commit;

 

-- ----------------------------

-- Records of tbl_pinyin

-- ----------------------------

truncate table tbl_pinyin;

INSERT INTO `tbl_pinyin` VALUES ('33641', '脛', 'jing4', '0');

INSERT INTO `tbl_pinyin` VALUES ('30749', '箅', 'bi4', '0');

INSERT INTO `tbl_pinyin` VALUES ('30750', '箢', 'yuan1', '0');

INSERT INTO `tbl_pinyin` VALUES ('30751', '篁', 'huang2', '0');

INSERT INTO `tbl_pinyin` VALUES ('30752', '篦', 'bi4', '0');

INSERT INTO `tbl_pinyin` VALUES ('30753', '篾', 'mie4', '0');

INSERT INTO `tbl_pinyin` VALUES ('30754', '簋', 'gui3', '0');

INSERT INTO `tbl_pinyin` VALUES ('30755', '簪', 'zan1', '0');

INSERT INTO `tbl_pinyin` VALUES ('30756', '籀', 'zhou4', '0');

INSERT INTO `tbl_pinyin` VALUES ('30757', '舄', 'xi4', '0');

INSERT INTO `tbl_pinyin` VALUES ('30758', '舢', 'shan1', '0');

INSERT INTO `tbl_pinyin` VALUES ('30759', '舨', 'ban3', '0');

.... ....

commit;

3. 創建漢字轉拼音函數（存儲過程、函數）

3.1. 創建存儲過程：PRC_GET_PYM

-- ----------------------------

-- procedure structure for PRC_GET_PYM

-- ----------------------------

delimiter $$

drop procedure if exists PRC_GET_PYM;

$$

create procedure PRC_GET_PYM(IN V_NAME varchar(256),OUT V_PYM varchar(256))

begin

declare i int default 1;

declare j int default 0;

declare V_PINYIN_TEMP VARCHAR(70);

declare V_NAME_TEMP varchar(200);

declare V_NAME_SIN varchar(10);

declare V_PINYIN_SIN varchar(10);

declare v_counter1 int(8);

'４','四'),'５','五'),'６','六'),'７','七'),'８','八'),'９','九'),'０','零') R3

into V_NAME_TEMP

from dual;

 

#循環獲得字符串拼音碼

myloop:loop

leave myloop;

end if;

 

select substr(V_NAME_TEMP, i, 1) into V_NAME_SIN from dual;

set i=i+1;

select count(*)

into v_counter1

select concat_ws('',V_PINYIN_TEMP,V_PINYIN_SIN)

into V_PINYIN_TEMP

from dual;

end if;

end if;

select char_length(V_NAME) into j from dual;

if i > j then

leave myloop;

end if;

end loop;

#截取32位長度字符

if char_length(V_PINYIN_TEMP) > 32 then

select substr(V_PINYIN_TEMP, 1, 32) into V_PYM from dual;

else

select V_PINYIN_TEMP into V_PYM from dual;

end if;

end;

$$

delimiter ;

3.2. 創建存儲過程：SP_PINYIN

-- ----------------------------

-- procedure structure for SP_PINYIN

-- ----------------------------

delimiter $$

drop procedure if exists SP_PINYIN;

$$

create procedure SP_PINYIN(IN hanzi varchar(256),OUT pinyin varchar(256))

begin

declare aword varchar(200);

declare aresult varchar(200);

declare temp1 varchar(20);

declare len int default 0;

declare point int default 1;

declare charword varchar(20);

declare charlen int default 1;

#定義游標標志變量

declare done int default false;

#定義游標

declare cur_pinyin cursor for

select PY from TBL_PINYIN

where word=substr(aword, point, charlen);

#指定游標循環結束時的返回值

declare continue HANDLER for not found set done=true;

select ltrim(rtrim(hanzi)) into aword from dual;

select char_length(aword) into len from dual;

#<<LABEL1>>

while point <= len do

select '' into temp1 from dual;

select substr(aword, point, 1) into charword from dual;

if (charword is not null and charword != ' ') then

select concat_ws(' ',aresult,charword) into aresult from dual;

else

select 2 into charlen from dual;

end if;

#打開游標

open cur_pinyin;

#開始循環處理游標里的數據

read_loop:loop

#獲得游標當前指向的一條數據

fetch cur_pinyin into temp1;

#判斷游標的循環是否結束

if done then

leave read_loop;

end if;

end loop; #結束游標循環

#關閉游標

close cur_pinyin;

if (point = 1) then

set aresult = temp1;

else

select concat_ws(' ',aresult,temp1) into aresult from dual;

end if;

select point+charlen into point from dual;

end while;

#輸出結果

select aresult into pinyin from dual;

end;

$$

delimiter ;

3.3. 創建函數：to_pinyin

-- ----------------------------

-- function structure for to_pinyin

-- ----------------------------

delimiter $$

drop function if exists to_pinyin;

$$

create function to_pinyin(v_hanzi varchar(256),v_type int)

returns varchar(256)

begin

declare strTemp VARCHAR(200);

declare strResult VARCHAR(200);

declare strHanzi VARCHAR(200);

declare strTemp1 VARCHAR(200);

declare v_subb VARCHAR(100);
