string or binary data would be truncated

Question

我有一个网页，我在其中添加了对数据的更新，后来又很好用，当我今天添加数据时，我有此错误字符串或二进制数据将被截断...尽管我在其他PC上进行了测试，但未出现此错误再次是什么问题。

Answer 1

That's the error message you get, if you attempt to enter data that is longer than the underlying 'backing' column in a database.

[It seems likely you entered different data on the two PC's you tested on]

Answer 2

如果尝试在数据库列中放入太长的字符串（例如varchar（3）中的“ abcd”），则会收到类似的错误。
