Parameters

[in]	tableName_	Name of the table to filter. This may be the name of a collection, a table, or a view (when chaining queries). If filtering a collection, all child tables where the filter expression is valid will be filtered; the filtered result tables will then be placed in a collection specified by viewName.
[in]	viewName_	If provided, then this will be the name of the view containing the results. Has the same naming restrictions as tables.
[in]	expression_	The select expression to filter the specified table. For details see Expressions.
[in]	options_	Optional parameters. gpudb::filter_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. gpudb::filter_view_id: view this filtered-view is part of. The default value is ''. gpudb::filter_ttl: Sets the TTL of the view specified in viewName.
