  • input_table: company1_stock, which has the daily stock prices from 1961 to 1962, excluding weekends and holidays

    The examples use the Interpolator function to calculate hypothetical stock prices for the excluded days.

  • time_table: time_table1

    The examples use the TimeInterval argument, but in any example, you can substitute time_table1 for the TimeInterval argument and get the same result. Interpolator Example 1: Aggregation includes equivalent SQL calls.
