[Gvsig_english] Sql language in the shapefile filter

[Marcus C. England]

I was just now able to get it to work by using the "fips" code and no 
quotes around the attribute I want to select. Apparently you can't have 
quotes in your SQL syntax, but without the quotes I would get an error 
because of spaces between Los, Angeles and County.

In summation:

WHERE fips = 6037          WORKS

WHERE county = Los Angeles County           GETS AN ERROR THROWN BACK

Quotes do not work either.

Does anyone know a work-around that would allow the second one to work?
