We often use GridView control, but sometimes, too much content is displayed, which can easily lead to page deformation and ugliness. Therefore, sometimes, in order to be beautiful, we only need to display the first few strings, and the rest can be represented by ellipsis. Here is a code for SQL intercepting strings, which can be taken away if necessary. Thank you
Select substring (column name, start, end) as column name from table
For example: substring (m_download, 0,20) as M_ download from Movie
