Question: I have declared my anchor style like this:

```
.disabledanchor a,
.disabledanchor a:hover,
.disabledanchor a:focus {
color: inherit;
cursor: inherit;
text-decoration: inherit
}

```

What should I pass to the jquery addclass to apply this style? 

Thanks,
Chris.

Answer: 
In case it's not obvious from all the other answers yet, you should create a B-tree [index](http://dev.mysql.com/doc/refman/5.6/en/optimization-indexes.html) on the `epoch` column.

Also, if you're not yet familiar with [using `EXPLAIN` to study the efficiency of your queries](http://dev.mysql.com/doc/refman/5.6/en/execution-plan-information.html), you should be.
You basically should create individual indexes for all the table fields you are searching on your WHERE clause. Combined indexes (with more than one field) should be used in more complex queries but bear in mind that indexes consume database space and resources.

I'm not sure that you can create indexes on myISAM tables - I'm not very knowledgable on MySQL as I prefer real databases ;-) - but if you can't then you should convert the table in question to InnoDB format and then create the indexes you need.

BTW, you mention that your table is not normalizable - that cannot be right, every table is normalizable to some degree depending on the amount of time/effort you want to put into it.
Sometimes, as data grows bigger that is the only way to go, but 300000 rows isn't much really.

Good luck with your efforts!
