Quoted strings appear in query output in different forms, as shown in the section below.
Quotes should NOT appear in query output. Strings must be stripped of their leading and prevailing quotes. (I am referring to this character - " )

{code}
Snippet of data from airports.cv file, first three lines, the first line has header information.

[root@centos-01 airport_CSV_data]# head -3 airports.csv
"id","ident","type","name","latitude_deg","longitude_deg","elevation_ft","continent","iso_country","iso_region","municipality","scheduled_service","gps_code","iata_code","local_code","home_link","wikipedia_link","keywords"
6523,"00A","heliport","Total Rf Heliport",40.07080078125,-74.9336013793945,11,"NA","US","US-PA","Bensalem","no","00A",,"00A",,,
