与Firebird SUSPEND

Question

我有一个来自Firebird数据库的存储过程，该数据库通过该过程多次调用SUSPEND。我不是这个程序的作者，也不是我非常擅长Firebird语法，但是Firebird docs说明了以下内容：

  

使用SUSPEND将一行数据从一个过程返回给其调用者。

我正在使用将过程转换为SQL Server等效项的软件，但是唯一未转换的部分是SUSPEND语句。所以，我已经评论过它来获取在SQL Server中创建的过程，但现在当我执行它时，我没有得到任何数据。在转换的SQL Server版本中，SUSPEND发生在游标循环中。在Firebird版本中，它出现在for循环中。

我正在执行这样的程序......

EXEC MY_CONVERTED_FB_PROCEDURE ARG1,ARG2,ARG3, etc...

在Firebird中，我通常会这样做

SELECT * FROM MY_FB_PROCEDURE (ARG1,ARG2,ARG3,...)

给了我结果集。

我的问题是，是否有人可以分享他们可以共享的自定义函数或代码片段，我可以添加代替SUSPEND语句，以便SQL Server将像Firebird一样执行相同的过程？

完全转换的SQL Server程序（已删除SUSPEND）
