Filter by Table

Filters objects in one table based on objects in another table. The user must specify matching column types from the two tables (i.e. the target table from which objects will be filtered and the source table based on which the filter will be created); the column names need not be the same. If a input parameter view_name is specified, then the filtered objects will then be put in a newly created view. The operation is synchronous, meaning that a response will not be returned until all objects are fully available in the result view. The return value contains the count (i.e. the size) of the resulting view.

Input Parameter Description

Name	Type	Description
table_name	string	Name of the table whose data will be filtered. Must be an existing table.
view_name	string	If provided, then this will be the name of the view containing the results. Has the same naming restrictions as tables. The default value is ''.
column_name	string	Name of the column by whose value the data will be filtered from the table designated by input parameter table_name.
source_table_name	string	Name of the table whose data will be compared against in the table called input parameter table_name. Must be an existing table.
source_table_column_name	string	Name of the column in the input parameter source_table_name whose values will be used as the filter for table input parameter table_name. Must be a geospatial geometry column if in 'spatial' mode; otherwise, Must match the type of the input parameter column_name.
options	map of string to strings	Optional parameters. The default value is an empty map ( {} ). Supported Parameters (keys) Parameter Description 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. filter_mode String indicating the filter mode, either in_table or not_in_table. The default value is in_table. The supported values are: in_table not_in_table mode Mode - should be either spatial or normal. The default value is normal. The supported values are: normal spatial buffer Buffer size, in meters. Only relevant for spatial mode. The default value is '0'. buffer_method Method used to buffer polygons. Only relevant for spatial mode. The default value is normal. Supported Values Description normal   geos Use geos 1 edge per corner algorithm max_partition_size Maximum number of points in a partition. Only relevant for spatial mode. The default value is '0'. max_partition_score Maximum number of points * edges in a partition. Only relevant for spatial mode. The default value is '8000000'. x_column_name Name of column containing x value of point being filtered in spatial mode. The default value is 'x'. y_column_name Name of column containing y value of point being filtered in spatial mode. The default value is 'y'.

Output Parameter Description

Name	Type	Description

info	map of string to strings	Additional information.
