在对stackoverflow进行一些搜索之后，我无法找到解决问题的方法。希望它并不那么难。
我试图将用户定义的变量用作创建视图语句的一部分。
我能够使用Prepare命令获得实际的select语句（如下所示）。我的问题是，当我尝试运行＆＃34;创建视图＆＃34;部分代码，我不断收到错误。不用多说，这里是MySQL代码：
这就是我想要做的事情（请注意，用户定义的变量位于＆＃34;有＆＃34;子句的最后）
create view `co 1_class` as
select all_class_qry.job_number, all_class_qry.companyid, all_class_qry.classcode, all_class_qry.class, all_class_qry.`standard title`, sum(all_class_qry.`# incmbts`) as `sumof# incmbts`,
avg(all_class_qry.`avgofannual base salary`) as `avgofavg base`, sum(all_class_qry.elig) as `sumof# recv`, avg(all_class_qry.`avgofbonus salary`) as `avgofavg bonus`,
avg(all_class_qry.`total cash`) as `avgoftotal cash`, avg(all_class_qry.`avgofposition min`) as `avgofavg min range`, avg(all_class_qry.`avgofposition mid`) as `avgofavg mid range`,
avg(all_class_qry.`avgofposition max`) as `avgofavg max range`
from all_class_qry
group by all_class_qry.job_number, all_class_qry.companyid, all_class_qry.classcode, all_class_qry.class, all_class_qry.`standard title`, all_class_qry.companyid
having (((all_class_qry.companyid)=@form_fwid_num));
就我所做的准备陈述而言：
set @co_1_class_qry = 'select all_class_qry.job_number, all_class_qry.companyid, all_class_qry.classcode, all_class_qry.class, all_class_qry.`standard title`, sum(all_class_qry.`# incmbts`) as `sumof# incmbts`,
avg(all_class_qry.`avgofannual base salary`) as `avgofavg base`, sum(all_class_qry.elig) as `sumof# recv`, avg(all_class_qry.`avgofbonus salary`) as `avgofavg bonus`,
avg(all_class_qry.`total cash`) as `avgoftotal cash`, avg(all_class_qry.`avgofposition min`) as `avgofavg min range`, avg(all_class_qry.`avgofposition mid`) as `avgofavg mid range`,
avg(all_class_qry.`avgofposition max`) as `avgofavg max range`
from all_class_qry
group by all_class_qry.job_number, all_class_qry.companyid, all_class_qry.classcode, all_class_qry.class, all_class_qry.`standard title`, all_class_qry.companyid
having (((all_class_qry.companyid)=?));';
prepare stmt1 from @co_1_class_qry;
execute stmt1 using @form_fwid_num;
同样，我100％能够运行这三个命令^但我想提出
'create view `co 1_class` as'
就在@ co_1_class_qry字符串的开头。
我只能想象必须有一种方法可以将用户定义的变量用作create view / table语句的一部分，以及更好的方法。提前谢谢！
注意：这是MySQL不断收到的错误消息 -
09:27:09 prepare stmt1 from @co_1_class_qry
Error Code: 1351. View's SELECT contains a variable or parameter 0.062 sec
