我试图运行的查询是我通常只在一个直接的SQL窗口（使用PL / SQL开发人员）和＆amp;获取提示值。
我想在PL / SQL中编写一个函数/程序，它将从一个查询中提取值列表（也在for循环中使用此查询）并逐个在第二个查询中运行这些值，然后返回那些值并输出它们。
我认为我很接近，但继续得到并非所有变量都是绑定错误。我没有正确地声明变量吗？
当我运行代码并注释掉函数get_case_count和函数调用时，它运行得很好。
以下是代码（根据答案1的建议更新）：
declare
skunumber integer;
scounter integer;
function get_case_count (skunum integer)
return integer
is
numcases integer := 0;

似乎是skunum变量提出了问题，但同样，我不知道该如何处理。如果有人对如何运行这个有更好的建议，我将非常感激。
提前致谢！
- UPDATE 我尝试了第一个答案建议，然后我重写了我的SQL并将第一行写成：
select total - (tcaseacp - sum(pickamt)-numlockstock-numlockloc-numlostcase-numqdcase-qainvreserve)- sum(pickamt) - sum(scratched) - sum(filled) into numcases
现在我收到了ORA-01722：无效号码
此数学运算中的所有值都是数值。我是否应该尝试在此处添加另一个选择，然后尝试选择....进入数字？我将使用我的新更改更新上面的代码。
答案 0 :(得分：0)
execute immediate :query_str
into :numcases
using :skunum;
这意味着query_str，numcases和skunum是绑定变量，即在PL / SQL之外声明的变量（通常在SQL * Plus中）。
对于PL / SQL变量，您应该简单地写一下：
execute immediate query_str
into numcases
using skunum;
此外，在这种情况下，不需要动态SQL。所以你可以摆脱query_str并直接编写你的查询：
select total ... into numcases
from ...
where SKU = skunum
group by ... ;
