The error message in Asp.net indicates that "the string or binary data will be truncated. The statement has been terminated ."

I haven't updated my blog for a long time. I encountered this problem when I was writing my website on ASP.net. The error message "truncates string or binary data. The statement has been terminated ."
After debugging, it is found that during data insertion, the length of the inserted data is larger than the length of the original data type. And the length of data stored
The length exceeds the length defined in your database. For example, if the field name varchar (10) is defined in your database and the length of the data you send to him exceeds 10 characters, an error will occur.
