Extracted fields

• Field: The type of field to extract.
  • Year: The year number will be extracted and appended as an integer column.
  • Year (Week-based): The year based on the week will be extracted and appended as an integer column. Depending on the selected locale, week 1 of a year may already start in the previous year, or week 52 of a year may last until the next year (e.g., 30th Dec 2010 belongs to week 1 of year 2011 (locale en-US), so the extracted Year (week-based) would be 2011 while the extracted Year would be 2010).
  • Quarter: If checked, the quarter of year will be extracted as a number in range [1-4] and appended as an integer column.
  • Month (Number): If checked, the month of year will be extracted as a number in range [1-12] and appended as an integer column.
  • Month (Name): If checked, the month of year will be extracted as a localized name and appended as a string column.
  • Week: If checked, the week of year will be extracted as a number in range [1-52] and appended as an integer column. A partial week at the beginning of a year is handled according to the chosen locale.
  • Day of Year: If checked, the day of year will be extracted as a number in range [1-366] and appended as an integer column.
  • Day of Month: If checked, the day of month will be extracted as a number in range [1-31] and appended as an integer column.
  • Day of Week (Number): If checked, the day of week will be extracted as a number in range [1-7] and appended as an integer column. The numbering is based on the chosen locale.
  • Day of Week (Name): If checked, the day of week will be extracted as a localized name and appended as a string column.
  • Hour: If checked, the hour of day will be extracted as a number in range [0-23] and appended as an integer column.

  • Millisecond: If checked, the millisecond fraction of second will be extracted as number in range [0-999] and appended as an integer column.
  • Microsecond: If checked, the microsecond fraction of second will be extracted as number in range [0-999,999] and appended as an integer column.
  • Nanosecond: If checked, the nanosecond fraction of second will be extracted as number in range [0-999,999,999] and appended as an integer column.
  • Time Zone Name: If checked, the unique time zone name will be extracted as a non-localized name and appended as a string column.
  • Time Zone Offset: If checked, the time zone offset will be extracted as a localized, formatted number and appended as a string column.
• Column name: The name of the column populated with the values of the selected field.
