Extractors.Csv()

Summary

The Csv() extractor disallows the delimiter parameter and defaults the field delimiter to ',' (comma). All other parameters are the same. See Extractor Parameters (U-SQL) for all supported parameters and their defaults values.

Examples

  • The examples can be executed in Visual Studio with the Azure Data Lake Tools plug-in.

  • The example below uses the sample data provided with your Data Lake Analytics account. See Prepare source data for additional information.

      // Excel CSV (ANSI with ASCII only)
      // You need to quote ASCII with [] to make sure it is not read as a reserved U-SQL keyword
      @Trips =
          EXTRACT date    DateTime,
              driver_id   int,
              vehicle_id  int,
              trips       string // Array
           FROM "/Samples/Data/AmbulanceData/DriverShiftTrips.csv"
           USING Extractors.Csv(encoding: Encoding.[ASCII]);
    
      OUTPUT @Trips 
      TO "/Output/ReferenceGuide/BuiltIn/UDOs/extractorCsv_DriverShiftTrips.csv" 
      USING Outputters.Csv();
