mysql in desc not update entries as a problem caused by entry

 

Today met a mysql database update problem, being given as follows

 

So I looked at star_link_upgrade_history 

I did not see any problem.

Try the next update other items

 

Update cur_sw_ver items no problem.

View the next item database

 

type is a string and cur_sw_ver desc. Why not a problem then there is a problem.

 

Desc suddenly thought of a key, is not it can not use it as an entry, attempt to modify this entry's name, reconstruction of the table, update operations again no problem.

 

Do keep in mind as the key entry! ! !
