    getRecordsByColumnRaw

    public RawGetRecordsByColumnResponse getRecordsByColumnRaw(GetRecordsByColumnRequest request) throws GPUdbException
    For a given table, retrieves the values from the requested column(s). Maps of column name to the array of values as well as the column data type are returned. This endpoint supports pagination with the offset and limit parameters.

    Window functions, which can perform operations like moving averages, are available through this endpoint as well as createProjection.

    When using pagination, if the table (or the underlying table in the case of a view) is modified (records are inserted, updated, or deleted) during a call to the endpoint, the records or values retrieved may differ between calls based on the type of the update, e.g., the contiguity across pages cannot be relied upon.

    If tableName is empty, selection is performed against a single-row virtual table. This can be useful in executing temporal (NOW()), identity (USER()), or constant-based functions (GEODIST(-77.11, 38.88, -71.06, 42.36)).

    The response is returned as a dynamic schema. For details see: dynamic schemas documentation.

    Parameters:
    request - Request object containing the parameters for the operation.
    Returns:
    Response object containing the results of the operation.
    Throws:
    GPUdbException - if an error occurs during the operation.
