Detailed Description

A set of input parameters for const.

Calculates which objects from a table have a column that is within the given bounds. An object from the table identified by tableName is added to the view viewName if its column is within [lowerBound, upperBound] (inclusive). The operation is synchronous. The response provides a count of the number of objects which passed the bound filter. Although this functionality can also be accomplished with the standard filter function, it is more efficient.

For track objects, the count reflects how many points fall within the given bounds (which may not include all the track points of any given track).

gpudb::FilterByRangeRequest::FilterByRangeRequest ( )

inline

Constructs a FilterByRangeRequest object with default parameter values.

Definition at line 35 of file filter_by_range.h.

gpudb::FilterByRangeRequest::FilterByRangeRequest ( const std::string &  tableName_, const std::string &  viewName_, const std::string &  columnName_, const double  lowerBound_, const double  upperBound_, const std::map< std::string, std::string > &  options_  )

inline

Constructs a FilterByRangeRequest object with the specified parameters.

Parameters

[in]	tableName_	Name of the table on which the filter by range operation will be performed. Must be an existing table.
[in]	viewName_	If provided, then this will be the name of the view containing the results. Has the same naming restrictions as tables.
[in]	columnName_	Name of a column on which the operation would be applied.
[in]	lowerBound_	Value of the lower bound (inclusive).
[in]	upperBound_	Value of the upper bound (inclusive).
[in]	options_	Optional parameters. gpudb::filter_by_range_collection_name: Name of a collection which is to contain the newly created view. If the collection provided is non-existent, the collection will be automatically created. If empty, then the newly created view will be top-level.
