Index file ratio
Is there a correlation between myisam table file size and related .myi file size ? If I need to introduce additional index for some field in 40-50Gb table, would there be any concerns about my.ini settings like key_buffer_size etc. Is it possible to place index file to memory to speed up things during table alteration and then unload it ? Would that be rational ? regards, Khazret Sapenov CMS Inc.

Hi, I have a query that returns a list of numbers ranging from -10 to +10 I would like to be able to have a 2nd column where a result of 5 is 5 but -5 is also 5, so in effect all the negative (and only the negative) results are made positive to find the deviation from zero. so 5, 4, -3, 4, -1, 0 would become 5, 4, 3, 4, 1, 0 I have been searching for if then else in google so I could do if a 0 then a = 0-a but no joy. is there a function to make negative numbers positive? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
