Question

我遇到了问题，我在SQL中创建了一些表

CREATE TABLE customers (ID not null,
name varchar (20),
salary int,
PRIMARY KEY (ID)
);

现在我想把来自SQL的所有工资从PL / SQL脚本放到表中，但我想逐行放入它，我不知道怎么做，我想在for循环中抛出一些东西，是否有可能？

我想以这种方式做到这一点：

DECLARE
 type salaries is table of integers;
 tab salaries:= salaries();
BEGIN
 for i in 1.. (here for example numbers of IDs)
/* and here make just tab(i):= customers(i).salary; 
I know that it looks like in C++ or so but i don't know how to 
implement it in sql.*/

Answer 1

例如：

begin
for x in (select * from customers)
loop
  if x.id > 30 or upper(x.name) like '%BOSS%' then
     insert into custom_table (column1, column2, column3, column4)
         values x.id, upper(x.name), x.salary, x.salary * 1.2;
  end if;
end loop;
end;
