![]() In your instance, with your question being: (please do excuse my enterprise information management principle ego - im working on it ok!) The assumption also being that it will 'exist' without any security/access permissions, so there is risk there as well. This makes the data types more important. The CSV file contains no geometry, so im assuming you will be joining your data to another table that does have geometry. Whilst QGIS and other applications are fantastic at being flexible enough to allow us to visualize simple datasets (like a CSV file), these practices are not what I would consider 'best practice', particular for longer term, sustainable, reusable solutions. I'm going to suggest more of a theoretical/best practice answer rather than a technical solution. If you import the file to QGIS using Browser or ODSM, the attribute table looks like this:įurther information, please look at Comma Separated Value (.csv) The difference between dragging a CSV from the Browser and using the "Open Data Source Manager" is that "Open Data Source Manager (ODSM)" guesses data types of columns. It is also possible to specify explicitly the To be listed with double quotes and be comma separated (e.g., In a single line the types for each column have (YYYY-MM-DD), Time (HH:MM:SS+nn), DateTime (YYYY-MM-DD HH:MM:SS+nn)Ĭolumns through a descriptive file with the same name as the CSV file,īut a. Limited type recognition can be done for Integer, Real, String, Date Using CSVT file with the same name as the CSV file allows you to specify types of columns in a CSV file. The OGR CSV driver returns all attribute columns as string data types QGIS uses OGR in the background, and OGR interprets all columns as strings.
