下面的用户定义函数导致重复，这导致构建失败。测试函数的每个部分的最佳方法是什么，以便我可以找出问题所在？援助将是一个巨大的好处。
我之前从未真正调试过一个函数，因为我认为在插入用户定义的函数之前先将代码作为select运行。

答案 0 :(得分：0)
我经常尝试将UDF重写为存储过程以进行调试;您也可以在SQL Server中使用调试器（仅限开发环境）并逐步执行代码。
补充工具栏：使用GOTO的长UDF我会尝试看看你是否可以简化代码。
答案 1 :(得分：0)
我正在为该问题的关注者添加答案。
@TheGameiswar评论：不，您不能print来自UDF的语句。您甚至不能使用raiserror。
我们能做什么：
一种显而易见的方法是从UDF中提取代码并在单独的解决方案中对其进行测试，以提供测试输入。但是，我会假定任何人读此线程都已经做到了，并且没有帮助，因为他们需要在另一个数据的上下文中对其进行测试。因此，该问题仅在某些情况下会发生，而典型的输入无法重现。
@Lee的回答有点像我上次最后做的那样。我 复制 我的UDF到存储过程，将返回部分更改为日志记录，并在调用UDF的地方，我添加另一行以执行SP在UDF旁边。通过这种方式，我可以在完全相同的上下文中，在UDF和SP的复杂结构中获得所需的调试数据。完成调试后，我只注释了执行SP的那一行。非常非常简单而强大的调试。
如果可能的话，另一个不错的选择是将调试数据打包到返回变量（如果是表，特别是如果它具有Comment这样的字段）并进行处理在父SP中。
单步调试器完全没有用，因为我的问题通常埋在成吨的UDF和SP中，并且深度达二十万次迭代。
还可以使用xp_cmdshell将文本输出到文本文件，当然该文本文件将存储在服务器上。不过，这可能需要对服务器进行一些调整。感谢@LDerckx的回答（我没有测试过）：
exec xp_cmdshell 'echo "mytextoutput" >> c:\debuginfo.txt'
最后，即使在某些条件下（在UDF中设置），也可以明知地对要确定范围的变量调用错误。在我看来，这是不切实际的，因为您会在要确定范围的每个值时中断执行。
