up MySQL Error Code: 3 error writing file (Errcode: 28) up vote 5 down vote favorite I am trying to execute a query to return the number of records (which is around 4 millions). SELECT COUNT(DISTINCT col) FROM table; I am mysql change temp directory getting this error: mysql Error Code: 3 error writing file 'C:\Winows\temp\Myffd3.tmp' (Errcode: 28). What is the cause of the problem. How to fix it? I tried t search, It might seems a disk space issue ? But I have 21 GB free space in the C. Does count command fro one columns require more than this ? EDIT: : The temp file name is not permanent.
