mysql触发器跳出当前循环方法

set @num=@UnitLength/3;

label:

while i<@num do

     set @length=(select SUBSTRING(@unit_sid_fk,1,@UnitLength-3*i));

     set @sms_content=(select sms_content from sms_config where  sms_type='smsCall' and unit_sid_fk=@length);

     set @sms_counts=(select sms_counts from sms_config where sms_type='smsCall'and unit_sid_fk=@length);

     if @sms_content is not null then      

       insert into sms_task set mt_at_time=@date,mt_content=@sms_content,unit_sid_fk=@unit_sid_fk,mt_dst_num=@calltelephone,mt_add_time=@date,mt_group_id=@groupid,branch_num=@sms_counts,mt_dst_size='1',sms_channel='SMSPORT',mt_type_id='99';

       set New.sms_send='Y';     

 leave label;

     end if;

set i=i+1;

end while;

 

在while循环外面添加label:      用  leave label;  即可跳出当前循环。
