Re-arranging fields
Is there any reasonable way of re-arranging the order of columns in a table without losing their data? The best I could come up with was to copy the table, empty it, and then do an INSERT . SELECT specifying the new order of the fields.

This can also be achieved in following manner. a) Rename table to tablename_new b) create table Tablename (fieldnames and datatypes) Select field1,field2...fieldn from tablename_new; But why do you want to do it in first place ?

The best I could come up with was to copy the table, empty it, and then do an INSERT . SELECT specifying the new order of the fields. According to RDB theory, the order of the columns is immaterially, just as is the order of the rows. You should always explicitly name the columns in the order you want. Relying on their default order can lead to problems down the road. -- Just my 0.0002 million dollars worth, Shawn Where there's duct tape, there's hope. Perl is the duct tape of the Internet.

COUNT returned rows of a SELECT
Using MySQL commands only (not PHP's mysql_num_rows), is there a way to COUNT the number of rows returned from a SELECT.GROUP BY? My primary SELECT query is this: SELECT aviName,MAX(dateTime) FROM aviTrackerMain WHERE DATE(dateTime) LIKE CONCAT(DATE(NOW()),'%') GROUP BY aviName; And it faithfully returns x-number of rows. However, I want to be able to capture the number of rows it returns. If I have to I will use PHP, but I was hoping for a way to do it with just MySQL.
