When I use the Alter table structure command to alter any field, the table
change window comes up in which I can change the field name, structure etc.
But when I press the “alter table” command button, it comes up with an error
stating that Error number 7 – error in renaming of table “table name.myi” to
“sql-208…” and so on with (Errorcode 13). Thereafter I have to cancel the
window whence it says “you will lose changed structure ” and I have to say
“OK” to come out. Thus I am unable to change the structure of any table.
I am using MySQL ver 3.23.55 and latest version of SQLYog downloaded
recently on a Windows XP professional system.
