GPUdb.filter_by_value( table_name = None, view_name = '', is_string = None,
value = 0, value_str = '', column_name = None, options
= {} )
Calculates which objects from a table has a particular value for a particular column. The input parameters provide a way to specify either a String or a Double valued column and a desired value for the column on which the filter is performed. The operation is synchronous meaning that GPUdb will not return a response until all the objects are fully available. The response payload provides the count of the resulting set. A new result view which satisfies the input filter restriction specification is also created with a view name passed in as part of the input payload.
