我正在尝试遍历由第一个 select 语句提取的行（仅包含一列），然后使用我要执行 select 语句的该行的值。但这里的问题是我的第一个 select 语句返回三行，它可能更多取决于具体情况。但是当它到达主选择语句时，它会说“在这个 SELECT 语句中需要一个 INTO 子句”

在一个过程或函数中，你不能只是SELECT; 您必须使用以下方法之一SELECT 进入某事：

  • SELECT table.col1, table.col2 INTO var1, var2 FROM ...,或
  • OPEN <cursor> FOR SELECT table.col1, ...

在这种情况下，您需要OPEN <cursor> FOR SELECT...，并且OUT参数是您要选择的光标。例如，第一个SELECT应该开始为：

IF V_APPLICANTTYPE='IC'   then
  OPEN CapRefCursor FOR
    SELECT 'Company' as App_Type, ...

第二个SELECT（在 之后else if）需要做同样的事情。
