Q. Why have I got a large file called SQL.LOG that I can't delete?

A. This is the default name for the ODBC trace file - it defaults to the root of the C drive but can be moved or renamed.
答：这是ODBC的跟踪文件，默认在C盘的根目录下，并且不能移动和改名
Go to control panel/odbc (called data access components on W2K or latest MDAC's). Check the tracing option here and turn it off. You should then be able to delete the file.
打开控制面板/ODBC，检查跟踪（Trace）选项，并把它关闭，这时应该可以删除这个文件了。
