Queries
Clauses
The following groups of clauses exist:
Specific polygons
| Clause | As a polygon | As an item | Type |
|---|---|---|---|
| AREA | The requested data must intersect with this area. | It must be data of this area specifically. | ID indicating a specific area. |
| NEIGHBORHOOD | The requested data must intersect with this neighborhood. | It must be data of this neighborhood specifically. | ID indicating a specific neighborhood. |
| ZONE | The requested data must intersect with this zone. | It must be data of this zone specifically. | ID indicating a specific zone. |
| TERRAIN | The requested data must intersect with this terrain type. | It must be data of this type of terrain. There are no specific "instances" of terrain. | ID indicating a type of terrain. |
Unspecific polygons
| Clause | As a polygon | As an item | Type |
|---|---|---|---|
| AREA_WITH_ATTRIBUTE | The requested data must intersect with at least one area with this attribute. | N/A | Attribute name of one or more areas. |
| NEIGHBORHOOD_WITH_ATTRIBUTE | The requested data must intersect with at least one neighborhood with this attribute. | N/A | Attribute name of one or more neighborhoods. |
| ZONE_WITH_ATTRIBUTE | The requested data must intersect with at least one zone with this attribute. | N/A | Attribute name of one or more zones. |
| TERRAIN_WITH_ATTRIBUTE | The requested data must intersect with terrain with this attribute. | N/A | Attribute name of one or more terrains. |
Grids
| Clause | As a polygon | As an item | Type |
|---|---|---|---|
| MAXGRIDVALUE | It must intersect with at least this value on a grid overlay. | N/A | Decimal number. |
| MINGRIDVALUE | It must intersect with at most this value on a grid overlay. | N/A | Decimal number. |
| GRID | It must fall within this grid. | It must be data of this grid overlay specifically. | ID indicating a specific zone. |
| GRIDTYPE | It must fall within this type of grid. | It must be data of this type of grid, not a specific "instance" of this grid. | Technical name indicating a type of grid overlay. |
Note that each grid automatically covers the entire map, unless a minimum gridvalue or maximum gridvalue is defined. For queries such as GRIDAVG, this can be acceptable. However, for example, a query of SELECT_LANDSIZE_WHERE_GRID_IS_2 is functionally the same as SELECT_LANDSIZE.
Also note that when a GRIDTYPE is selected but multiple overlays of that type exist in the project, there are no guarantees on which overlay is used specifically.
Constructions
| Clause | As a polygon | As an item | Type |
|---|---|---|---|
| BUILDING | The requested data must intersect with this construction. | It must be data of this construction specifically. | ID indicating a specific construction. |
| NET_LOAD | The requested data must intersect with the building of this load. | It must be data of this load specifically. | ID indicating a load. |
| NET_CLUSTER | The requested data must intersect with buildings of loads of this cluster. | It must be data of this cluster specifically. | ID indicating a specific cluster. |
| FUNCTION | The requested data must intersect with constructions of this function. | It must be data related to this function type. | ID indicating a specific function. |
Item
| Clause | As a polygon | As an item | Type |
|---|---|---|---|
| ATTRIBUTE_MAX | It must intersect with at least this value of an attribute. | N/A | Decimal number. |
| ATTRIBUTE_MIN | It must intersect with at most this value of an attribute. | N/A | Decimal number. |
| ATTRIBUTE | The attribute of which to test the value. | N/A | Attribute name of any polygonal item. |
When neither a maximum or minimum value is specified, or when no attribute is specified, everything is considered
