Jukka, Add -oo QUOTED_FIELDS_AS_STRING=YES I don't remember the rationale for the default of this option to be NO. Presumably the use case while developping that was with a file generated by a CSV exporter always surrounding field content by double quotes.

[gdal-dev] Autodetect "0012" as string in CSV
Hi, The schema of a CSV file like this "00012",012345,1234,234.65,"text" is autodetected this way: ogrinfo csvtext.csv -oo autodetect_type=yes -al INFO: Open of `csvtext.csv' using driver `CSV' successful. Layer name: csvtext Geometry: None Feature Count: 1 Layer SRS WKT: (unknown) field_1: Integer (0.0) field_2: Integer (0.0) field_3: Integer (0.0) field_4: Real (0.0) field_5: String (0.0) OGRFeature(csvtext):1 field_1 (Integer) = 12 field_2 (Integer) = 12345 field_3 (Integer) = 1234 field_4 (Real) = 234.65 field_5 (String) = text It would be good to autodetect also "00012" as a string. Double quotes are correctly stripped of from "text" so I suppose that GDAL already knows that they are used for enclosing strings.
