Sql server 在尝试用SQL测试数据库时，正确的过程是什么？
我对数据库非常陌生，我完成了一项任务，我必须查看合并的实体关系图，然后创建删除表、表（带有约束和标识）、更改和索引。我很确定我已经正确地编写了所有的代码，但我唯一有点不确定的地方是，如何测试数据库在执行时是否真正起作用。我的指导老师给了我一个TestData.sql文件，我只需要引用数据库，然后执行它，它应该将所有数据插入表中，并正确地删除所有内容。我已经在SQLServerManagementStudio上正确地连接了所有这些，但是我忘记了为了测试表的正确执行应该采取哪些步骤。我会发布我的一些代码，你们可以看看。任何关于这个问题的信息都将不胜感激 此外，当它在测试数据SQL代码中说“重要！如果需要多次运行此脚本，则必须先删除并重新创建表以重置标识属性。”--这是否意味着如果我在尝试执行测试数据时遇到任何错误，我必须先执行DROP表，然后将所有表复制并粘贴回数据库文件？我实际上不需要再次手动键入所有表，只需要将它们重新输入为“新”，这样系统就会重置它的标识属性 如果你们需要我发布更多的代码来澄清，请告诉我。感谢您抽出时间阅读本文：） 更新：我在尝试执行TestData脚本时收到两条错误消息：“无效对象名'SaleDetail.”和“无效对象名'Author.”。我还提供了数据库脚本文件中的其余代码供您查看。我几乎可以肯定一切都是正确的 数据库表代码（这是完整的代码脚本）Sql server 在尝试用SQL测试数据库时，正确的过程是什么？,sql-server,Sql Server,我对数据库非常陌生，我完成了一项任务，我必须查看合并的实体关系图，然后创建删除表、表（带有约束和标识）、更改和索引。我很确定我已经正确地编写了所有的代码，但我唯一有点不确定的地方是，如何测试数据库在执行时是否真正起作用。我的指导老师给了我一个TestData.sql文件，我只需要引用数据库，然后执行它，它应该将所有数据插入表中，并正确地删除所有内容。我已经在SQLServerManagementStudio上正确地连接了所有这些，但是我忘记了为了测试表的正确执行应该采取哪些步骤。我会发布我的一些
我不知道你在问什么？你需要帮助的是什么？抱歉说得含糊不清，我不知道该怎么问这个问题。在创建数据库之后，您需要确保数据将实际填充到表中，对吗？我有两个独立的文件-一个是数据库，另一个是测试数据。我只是问你如何确保你的数据库正常工作。我相信我已经正确地将数据库引用到了测试数据中，但是我想知道为了测试数据库，我必须首先突出显示并执行哪些区域。我只需要确保数据库实际上正在填充表并删除它们，我只需要将所有这些移到一起。并删除delete语句。然后它将总是构建新表。这些表很小，所以十几次插入都需要几毫秒的时间。好吧，这只是因为我的讲师希望我们按照现在的方式使用这个测试数据脚本。它将删除所有旧数据并插入新数据。我已经执行了几次，它给了我一些我不太理解的错误信息。我将用剩下的代码更新我的帖子，并包含错误消息。任何指导都会很好！看着这个问题，我意识到它太模糊了，太愚蠢了。我道歉。我将尝试打破这一点，并将重新张贴，如果需要的话。无论如何谢谢你！
