TQL

TQL is short for Tygron Query Language. It provides a means of interacting with the data in a session from excel. It is comprised of a numer of key phrases, devided into 2 categories: statements and clauses. The statements indicate what interaction should take place. The clauses provide conditions which must be met for the interaction to take place.

Interactions can take place with the data in 2 ways: as item data or polygon data. Item data pertains to a specific component of a project, such as individual constructions, indicators, or globals. Polygon data pertains to geographic data; surface areas in the 3D world. Such as the footprint of constructions, the surface area of neighborhoods, or calculated grids. Depending on what kind of statement is used, the query will interact with its clauses treating them as items or as polygons.

Usage

TQL can be used in a number of situations. The most common situation where using TQL is required is when creating custom indicators or panels, using excel. To indicate which cells should contain certain data from the session, cells in an excel file can be named. The name would be a TQL query. When a calculation is to take place, the engine will place the data as described by the TQL query in that cell. Likewise, at the end of the calculation, all cells with a name which indicates data in the engine should be updated are read out, and the data indicated by the TQL query is updated with that value.

TQL can also be used to quickly check data in a project. When in editor mode, it's possible to open the query tool. With this tool, queries can be made and directly executed. The result is then presented to the user. This can be especially handy when its neccesary to quickly check whether a certain type of data is present or correctly readable. The query tool also functions both in and out of testruns, allowing a user to also check data in a project during a session.

It's also possible to execute TQL queries directly via the API. Although in most situations it's more effective to inspect data via the API directly, or to use events via the API directly, there are some TQL queries possible which perform some intermediate processing. Examples of this include the queries related to values of grids, or the multiplication of floor size with a related function value.

Statements

Statements are the primary part of a query. They indicate what must be done with data in a session. Statements start with either SELECT or UPDATE. SELECT statements retrieve data from a session. UPDATE statements write data into the session. All statements can interact with data, treating it as either item data or polygon data, depending on the exact statement.

Polygon statements

These statements interact with data as polygon data. This means that, depending on the clauses added to the query, they generally see how much surface area in the world meets a certain set of conditions.

Land polygons

Land polygon statements relate to the surface area of the land itself, regardless of what is built on it. These are mostly used for getting the sizes of areas, to then divide specific uses by.

Query	Value returned	Clauses for specific query	Clauses for entire group
LANDSIZE	Amount of surface area. (m2)	Grids	Specific polygons Attribute polygons Stakeholders Map types
DIKES	The amount of surface area taken up by dikes. (m2)	Dikes Timestates

Construction polygons

Construction polygon statements relate to surface area in use by constructions. These are mostly used for determining the amount of certain types of constructions, and their cumulative values.

Query	Value returned	Clauses for specific query	Clauses for entire group
LOTSIZE	Amount of surface area used by a construction. (m2)		Specific polygons Attribute polygons Grids Constructions Dikes Building categories Timestates Attributes Stakeholders Relations Layer types Map types Multipliers
FLOORSIZE	The amount of floorspace, based on constructions' lotsize and their amount of floors. (m2)
UNITS	The amount of housing units, based on construction's lotsize and their unit size.
LOTPOLYGONS	Whether something meets the criteria (1) or not (0). When used in a panel and the panel is opened, the polygon is highlighted.

Grid values

Grid statements relate to calculated values of grid overlays. These are used to retrieve calculated effects of built-in spatial calculation models.

Query	Value returned	Clauses for specific query	Clauses for entire group
GRIDAVG	The average value of a grid.		Specific polygons Attribute polygons Grids (Excluding the value clauses) Map types
GRIDSTDEV	The standard deviation of a grid.
GRIDSVOLUME	The surface area multiplied by the average grid value on that surface.
HEIGHT	The average height of the terrain. (mNAP)	Grids (Including the value clauses)

Item statements

These statements interact with data as item data. This means that, depending on the clauses added to the query, they retrieve a specific property of value related to a single component of a project, such as an area's attribute, or the name of a stakeholder.

Numeric values

Numeric value statements relate to attributes and globals, which are both numeric values which can be created, read, and written to during a session. These are mostly used as parameters in calculations of grid overlays, and as parameters in user-ceated excel files for indicators and panels.

Query	Value returned	Clauses for specific query	Clauses for entire group
ATTRIBUTE	The numeric attribute value of an item.	Specific polygons Constructions Network Interface Relations Map types	Variables
GLOBAL	The value of a global variable

IDs

ID statements are used when the identification number of a specific item is required. This is used when, for example, creating an event which affects a specific item. Another use can be to uniquely identify an item in user-defined calculations.

Query	Value returned	Clauses for specific query	Clauses for entire group
IDs	The numeric identifier value of an item.		Specific polygons Grids (Only GRID) Constructions Dikes Networks Stakeholders Interface Relations

Names

Name statements are used to retrieve the human-readable name of an item. This allows panels and indicators based on excels to display the same and appropriate texts throughout the entire project.

Query	Value returned	Clauses for specific query	Clauses for entire group
NAME	The name or human-readable version of a technical name.		Specific polygons Grids Constructions Dikes Building categories Timestates Networks Stakeholders Interface Indicators Terms Layer types Map types Multipliers

Active

Active statements are used to determine whether certain polygons are active or not. The engine will not consider inactive areas or neighborhoods in its calculations. Testing whether an item is active or not is often used to exclude those polygons from excel calculations as well.

Query	Value returned	Clauses for specific query	Clauses for entire group
ACTIVE	Whether the item is active/under consideration (1) or not (0).		Specific polygons (Only AREA and NEIGHBORHOOD)

Color

Color statements are used to retrieve the color of specific items. Color's support the user's ability to differentiate between pieces of data. These statements allow for indicators andpanels to display the same information with the same colors across the entire project, such as the colors of neighborhoods.

Colors can be retrieved in 2 ways. The color statement will return a hexadecimal value representing the color. It's also possible in most cases to retrieve the color by attribute, using SELECT_ATTRIBUTE_WHERE_NAME_IS_COLOR. In these cases the color is returned as a numeric value. For more information on this value, see the attribute article.

Query	Value returned	Clauses for specific query	Clauses for entire group
COLOR	The color of an item (hexadecimal value).		Specific polygons Constructions Stakeholders

State

State statements are used to determine what timestate an item is in, effectively testing at what point in its lifecycle of permission, construction, and demolition it currently is. This is mostly used to determine the progression of permissions and constructions; how far construction plans have progressed in the decision process of stakeholders.

Query	Value returned	Clauses for specific query	Clauses for entire group
STATE	What the current timestate is of an item.		Constructions (Excluding FUNCTIONS) Timestates

Network

Network statements are used to interact with data inherent to networks, such as the length of pipes. This is mostly used for cost- and efficiency calculations related to the extent of a network.

Query	Value returned	Clauses for specific query	Clauses for entire group
LENGTH	The length of pipes/lines/cables of networks.		Networks

Stakeholder finances

Stakeholder finance statements are used to retrieve the financial situation of stakeholders.

To affect the stakeholder finances using TQL, it's possible to update the value of a global, which is in turn connected directly to a stakeholder's finance.

Query	Value returned	Clauses for specific query	Clauses for entire group
EXPENSES	The costs incurred by a stakeholder during a session.		Stakeholders
REVENUE	The income of a stakeholder during a session

Indicator

Indicator statements can be used to interact with properties of indicators, allowing excels driving indicators to make use of properties of indicators defined in the editor.

These statements mostly facilitate the retrieval of the indicator targets.

Query	Value returned	Clauses for specific query	Clauses for entire group
TARGET	The target set for an indicator.		Building categories Interface (Only INDICATOR) Indicators

Session

Session statements can be used to retrieve data regarding the session itself. These don't require any clauses.

Query	Value returned	Clauses for specific query	Clauses for entire group
SESSIONSTATE	Whether the project is currently in editor mode (0), starting a session (1), or in a session/testrun (2).
TOKEN	The API token for this session.

Update statements

Update statements are a seperate kind of statement, which interact with data in the session not by reading it from the session but by altering it in the session. Update statements indicate the type of item to update, and the attribute which needs to be updated. Most update statements interact directly with item data, and a specific item must be specified to perform the update on. There are also update statements which do not affect items directly, but which affect that type of item based on whether it meets specific conditions, i.e. clauses.

Clauses

Clauses indicate the conditions which must be met for any data to be taken into account for a statement. In a query, they are connected to the statement using the phrase WHERE. Multiple additonal clauses can be added to a query using the phrase AND. Clauses added to a query are cumulative conditions which must all be met. When, for any data, at least one condition is not met, that data is not taken into account or affected by the query.

Clauses can be broadly grouped into 3 different groups: Common clauses, singular clauses, and modifying clauses. For any given statement, different clauses can be applied from across all these groups. The availability and function of clauses is also influenced by whether the statement dictates an interaction with polygon data or with item data. Some clauses may or may not be available at all, depending on this.

Common clauses

Common clauses are clauses which can be used by multiple statements and are commonly required.

Specific polygons
