You just need to escape the single quotes - this is accomplished by putting two single quotes together.

For example:

   Select * from mytable where name = 'foo'

would be expressed as

   'Select * from mytable where name = ''foo'''

I can't help you with the rest of it; it sounds rather convoluted...
