YC (TQL)

Instead of specifying a clause parameter with a particular Item ID, it is possible to use the 'YC' characters for its value. The result of using 'YC' for the clause value, is the automatic creation of multiple TQL statements, one with each Item ID for that Clause Parameter, but only the Items that are covered by the calculated Search Polygon of the TQL statement. The Search Polygon is calculated by overlapping the clause polygon. Per clause type it is indicated if it limits the 'Search Polygon'. Internally, the resulting TQL statements are placed in a single array; Similarly the result will be an array of TQL result arrays.

Example

Neighborhoods in an example project

Areas in an example project

Consider the following (simplified) Neighborhood data of a project:

[ {
  "id" : 0,  "name" : "East Side",
  "polygons" : { "type" : "MultiPolygon", "coordinates" : [ [ [ [ 250.0, -500.0 ], [ 500.0, -500.0 ], [ 500.0, 0.0 ], [ 250.0, 0.0 ], [ 250.0, -500.0 ] ] ] ]  }
}, {
  "id" : 1,  "name" : "West Side",
  "polygons" : {  "type" : "MultiPolygon", "coordinates" : [ [ [ [ 0.0, -500.0 ], [ 250.0, -500.0 ], [ 250.0, 0.0 ], [ 0.0, 0.0 ], [ 0.0, -500.0 ] ] ] ]  }
} ]

and the Area data:

[ {
  "id" : 0,  "name" : "Upper Left",  
  "polygons" : {    "type" : "MultiPolygon",    "coordinates" : [ [ [ [ 110.0, -110.0 ], [ 110.0, -100.0 ], [ 100.0, -100.0 ], [ 100.0, -110.0 ], [ 110.0, -110.0 ] ] ] ]  }
  }, {
  "id" : 1,  "name" : "Upper Right",  
  "polygons" : {    "type" : "MultiPolygon",    "coordinates" : [ [ [ [ 435.0, -95.0 ], [ 425.0, -95.0 ], [ 425.0, -105.0 ], [ 435.0, -105.0 ], [ 435.0, -95.0 ] ] ] ]  }
  }, {  
  "id" : 2,  "name" : "Lower Left",  
  "polygons" : {    "type" : "MultiPolygon",    "coordinates" : [ [ [ [ 165.0, -425.0 ], [ 165.0, -415.0 ], [ 155.0, -415.0 ], [ 155.0, -425.0 ], [ 165.0, -425.0 ] ] ] ]  }
  }, {  
  "id" : 3,  "name" : "Lower Right",  
  "polygons" : {    "type" : "MultiPolygon",    "coordinates" : [ [ [ [ 315.0, -395.0 ], [ 325.0, -395.0 ], [ 325.0, -385.0 ], [ 315.0, -385.0 ], [ 315.0, -395.0 ] ] ] ]  }
} ]

Also Consider the situation where a TQL statement is present in the Text Body of a Template Text Panel. This Template Panel is applied on neighborhoods, creating two Text Panel instances, one automatically linked to Neighborhood 'East Side' and one to 'West Side.

The TQL statement

SELECT_NAME_WHERE_AREA_IS_YC_AND_NEIGHBORHOOD_IS_0

for the Text Panel linked to Neighborhood "East Side" is internally replaced with a list of TQL statements, separated by comma's,

[SELECT_NAME_WHERE_AREA_IS_1_AND_NEIGHBORHOOD_IS_0], [SELECT_NAME_WHERE_AREA_IS_3_AND_NEIGHBORHOOD_IS_0]

Its result will be an array of name arrays, separated by comma's, for example:

["Upper Right"], ["Lower Right"]

Clause Parameters

The YC value can be used in the following TQL Clause parameters:

• Address (TQL Param)
• Area (TQL Param)
• Building (TQL Param)
• Neighborhood (TQL Param)
• Zone (TQL Param)
• Net load (TQL Param)
• Net line (TQL Param)

Notes

• The following variants on YC exist:
  • YCA: A combination between YC and YA.
  • YCK: A combination between YC and YK.
