Select query with a constant against a Spider table produces incorrect results.

When running a select query against a spider table and using a constant the constant value is inserted into the result set instead of the selected value.

For example:

In a table with this dataset

ID | Value
1 | One
2 | Two
3 | Three
4 | Four

select "sample", value from spider.table; produces

sample,One
sample,sample
sample,sample
sample,sample

If you run the query against an InnoDB table you get these results.

select "sample", value from InnoDB.table;

sample,One
sample,Two
sample,Three
sample,Four
