Sqlexception (0 × 80131904): truncates string or binary data.

The following error occurs during debugging of SQL database addition:

Error! [8152] system. Data. sqlclient. sqlexception: truncates string or binary data. The statement has been terminated. At system. Data. sqlclient. sqlcommand. executenonquery () at Sand. webform2.page _ load (Object sender, eventargs E) in\ XX. XXX. xx \ sxd \ sand \ add2.aspx. CS: Line51

After analysis, it turns out that the data type selected in my database is incorrect (or the length of the current data type is longer ), news content should be of the text type, but I use varchar. Just change the data type of this field. To put it bluntly, the length defined by the selected data type is smaller than the content to be inserted.
