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: 
there is a thing called [index](http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html) for this purpose

```
CREATE INDEX epoch ON tablename (epoch)

```
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.
