我无法使用某些emailids保存详细信息。我收到此错误"The index entry of length 904 bytes for the index 'IX_companyinfo_exhibition' exceeds the maximum length of 900 bytes."
当我输入以下电子邮件时，它没有被保存：
info@combilift.com
marketing@hildaautomation.in
info@pakona.com
info@himedialabs.com
info.lho@liebherr.com
在调试期间，在catch块中，我发现我收到此错误"The index entry of length 904 bytes for the index 'IX_companyinfo_exhibition' exceeds the maximum length of 900 bytes."

电子邮件的存储过程是否需要进行任何更改？ 我没有为这个问题做过多少尝试，因为我没有得到这个错误的含义。我用谷歌搜索它，我唯一得到的是修改列。
我是C＃的初学者，并且是第一次处理存储过程。非常感谢任何帮助。
答案 0 :(得分：1)
你能否提供
的详细资料IX_companyinfo_exhibition
在包含非聚集索引的表中，索引键列的总大小限制为900 bytes。
我认为您正在使用companyinfo（我认为是varchar）或其他字段作为索引键或索引IX_companyinfo_exhibition中的包含列，这不应该用作索引，因为它很大而且它是不是一个好的索引键，也不是一个包含的列（由于它的大小）。您可以在表中的索引中查看它，该错误与表中创建的索引之一中使用的键有关，而不是存储过程中的错误。
只需检查索引并禁止/删除使用大字段（varchar，nvarchar等等）作为索引键或包含列。我还建议您阅读有关索引的更多内容以及用作正确索引的最佳字段，因为创建不正确的索引/索引太多可能会对您的系统造成损害，而不是更好。
您可以将其视为preference。
