mysql 存储过程 参数 没有数组的处理方式

原来mysql存储过程是没有数组概念的，网上资料也少。drop procedure if exists Pro_DeleteLog; -- 存在即删除create procedure Pro_DeleteLog( Qualification varchar(100)) -- 定义参数begin declare i int ; declare Start1 int; declare Length int ; declare TotalLenght int ; declare filed varchar(100) ; declare sqlStr varchar(2000) ; declare stmtNovelSearch varchar(2000) ; set i=1; set Start1=1; set Length=0; set TotalLenght=length(Qualification); -- 计算输入参数长度 select TotalLenght; while i <=TotalLenght do -- i=1 开始 -- select SUBSTRING(Qualification,i,1); if(SUBSTRING(Qualification,i,1)=',') -- 注意 mysql 的substring函数截取字符串是从1开始的，而不是0 与java JavaScript不同。-- 从第i位开始截取一个字符，看是否等于， then set filed=SUBSTRING(Qualification,Start1,Length);-- 从start1开始截取length长度的字符 select filed; set @sqlStr = CONCAT('insert into end_results(accessid,filedName,errinfo)select * from (select w1.accessid ,\'',filed ,'\' as filedName,',filed,' from wdd_audit w1 ,wdd_dbaccessinfo w2 where w1.accessid=w2.accessid )a where not exists(select e.',filed ,' from exp_results e where e.',filed,'=a.',filed,' or(e.',filed,' is null and a.',filed,' is null) );'); -- 拼装sql语句 select @sqlStr; PREPARE stmtNovelSearch FROM @sqlStr; -- prepare 必须采用这种传参方式 execute stmtNovelSearch; deallocate prepare stmtNovelSearch; set Start1=i+1; set Length=0; else set Length=Length+1; -- 如果不是， 则截取的长度加1 end if; set i=i+1; end while;end-- 调用存储过程 字段名以，分隔 注意最后 ， 结尾call Pro_DeleteLog('payload,backresult,dataset,effectrow,clientuser,loginuser,clientprg,')
