Question

似乎这应该很容易，但语法不适合我。我正在尝试更新现有的行 - 我发现的第一行是'新'。然后我想返回一个带有键和其他两个值的分隔字符串：

create or replace procedure usp_direct_print_task_deque 
(
  taskNa in char
 ,environmentCd in char
) as 
begin
  declare rowkey number;

  select '~' || rowversion || '~' || target_document || '~' || target_printer 
   as delimited_data
   , rowversion 
  from AFD1.bt_direct_print_tasks
  where environment_cd = environmentCd 
   and task_na = taskNa  
   and task_status = 'new'
   and rownum = 1;

  update bt_direct_print_tasks
  set taskStatus = 'processing'
  where rowversion = rowkey;

  return delimited_data;  

end usp_direct_print_task_deque;

您需要定义OUT参数变量，例如x_delimited_data和x_rowkey，以分别保存delimited_data和rowkey的值。然后将SELECT更改为SELECT... INTO x_delimited_data, x_rowkey。（我假设rowkey是您选择的rowversion）。然后将return delimited_data;更改为return;

Oracle程序更新一行并返回其密钥？
