【数据库】MySql分割字符串

上论坛时看到一个骨骼清奇的分割字符串算法。

DROP TABLE IF EXISTS Tmp_AreaCode;  
    CREATE TABLE Tmp_AreaCode(  
        string VARCHAR(800)
    )ENGINE = MYISAM DEFAULT CHARSET = utf8 ;

SET @sqlstr1 = CONCAT(CONCAT("INSERT INTO Tmp_AreaCode VALUES(\'",REPLACE(areacodesp,\',\',"\'),(\'")),"\')");

 

set areacodesp = \'01,02,03\';

execute @sqlstr1;

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

INSERT INTO Tmp_AreaCode VALUES(\'01\')(\'02\')(\'03\');
