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, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table.
view_name string If provided, then this will be the name of the view containing the results, in [schema_name.]view_name format, using standard name resolution rules and meeting table naming criteria. Must not be an already existing table or view. 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, in [schema_name.]table_name format, using standard name resolution rules. 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
create_temp_table

If true, a unique temporary table name will be generated in the sys_temp schema and used in place of input parameter view_name. This is always allowed even if the caller does not have permission to create tables. The generated name is returned in qualified_view_name. The default value is false. The supported values are:

  • true
  • false
collection_name [DEPRECATED--please specify the containing schema for the view as part of input parameter view_name and use Create Schema to create the schema if non-existent] Name of a schema for the newly created view. If the schema is non-existent, it will be automatically created.
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
count long The number of records in input parameter table_name that have input parameter column_name values matching input parameter source_table_column_name values in input parameter source_table_name.
info map of string to strings

Additional information. The default value is an empty map ( {} ).

Possible Parameters (keys) Parameter Description
qualified_view_name The fully qualified name of the view (i.e. including the schema)
