Re: COMPARE WITH INNODB QUERY CHANGE

Hi.

The SQL standard does not guarantee a certain order of rows without ORDER BY. It may woork in some situations. But if you delete rows and enter new ones, the sort order is broken.

I am not a query expert. But I guess that ORDER BY length(code) might help.

An index on 'order' might also be helpful. But I don't know if it can be used with the instr function.

This question does not really target at memory tables.I suggest to ask in the "General" forum.

Regards
Ingo
