希望这对您有所帮助另外，您可以更详细地描述一下，您说显示的表是父表。子项的结构是什么，我假设它保存分配的批次号？到目前为止，我所做的是我可以得到父项分配和分配的范围，但我还没有找到如何从这两个信息中找出未分配的范围，选择*来自凭证批次分配，其中父项FK为空，通道FK为1，ID为43；从凭证\批次\分配中选择*，其中父项\ FK不为空，父项\ FK=43；您还可以更详细地描述一下，您说显示的表是父表。子项的结构是什么，我假设它保存分配的批次号？到目前为止，我所做的是我可以得到父项分配和分配的范围，但我还没有找到如何从这两个信息中找出未分配的范围，选择*来自凭证批次分配，其中父项FK为空，通道FK为1，ID为43；从凭证\批次\分配中选择*，其中父项\ FK不为空，父项\ FK=43；我已经试过了，我给出了这个错误，你的SQL语法有错误；检查与您的MySQL服务器版本相对应的手册，以了解在第4行“警告”-->W 1:您的SQL语法中有错误，请在“[END]附近使用正确的语法，从SELECT a.ID AS ID，a.PARENT_FK AS PARENT.”；查看与您的MySQL服务器版本对应的手册，了解在第4Hmmm行的“[END]附近使用的正确语法，选择a.ID作为ID，a.PARENT_FK作为PARENT”，是的，我知道了。我的脚本是为在MSSQL而不是MySql中使用而编写的。我会看看它是否可以修改。我已经将修改后的MySql脚本添加到ab中
我无法回答。希望它有用这个很好，我会花几个月的时间让它工作@DMK该脚本可以工作，但可能会在一些方面得到简化，从而使其更易于阅读，更高效。可能值得添加代码作为帖子，以获取一些意见。但就目前而言，它完成了所需的工作。很高兴它有用。我已经试过了，我给出了这个错误，如果您的SQL语法有错误；检查与您的MySQL服务器版本相对应的手册，以了解在第4行“警告”-->W 1:您的SQL语法中有错误，请在“[END]附近使用正确的语法，从SELECT a.ID AS ID，a.PARENT_FK AS PARENT.”；查看与您的MySQL服务器版本对应的手册，了解在第4Hmmm行的“[END]附近使用的正确语法，选择a.ID作为ID，a.PARENT_FK作为PARENT”，是的，我知道了。我的脚本是为在MSSQL而不是MySql中使用而编写的。我会看看它是否可以修改。我已经在上面的答案中添加了修改后的MySql脚本。希望它有用这个很好，我会花几个月的时间让它工作@DMK该脚本可以工作，但可能会在一些方面得到简化，从而使其更易于阅读，更高效。可能值得添加代码作为帖子，以获取一些意见。但就目前而言，它完成了所需的工作。很高兴它有用。
