| | TQL is short for Tygron Query Language. It provides a means of obtaining and adjusting data of a [[session]]. It is comprised of a number of key phrases, that can be divided into 2 categories: statements and clauses. The statements indicate what data interaction should take place; retrieving using a [[Select (TQL)|<code>SELECT</code>]] statement, or adjusting using an [[Update (TQL)|<code>UPDATE</code>]] statement. The clauses provide a means to filter the data the interaction is applied to. A query always consists of exactly 1 statement and 0 or more clauses. Each clause always consists of a [[Clause (TQL)|Clause parameter]] and a value. |

Property data pertains to a specific component of a [[project]], such as individual [[building]]s, [[indicator]]s, or [[global]]s. Polygon data pertains to geographic data; surface areas in the [[project area]], such as the lot size of [[building]]s, the surface area of [[neighborhood]]s, or calculated [[grid overlay|grid]]s. Depending on what kind of statement is used, the query will interact with its clauses treating them as items or as polygons. |

| TQL is short for Tygron Query Language. It provides a means of obtaining and adjusting data of a [[session]]. It is comprised of a number of key phrases, divided into 2 categories: statements and clauses.

|
| |
|
| 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 [[construction]]s, [[indicator]]s, or [[global]]s. Polygon data pertains to geographic data; surface areas in the [[3D world]]. Such as the footprint of [[construction]]s, the surface area of [[neighborhood]]s, or calculated [[grid overlay|grid]]s. Depending on what kind of statement is used, the query will interact with its clauses treating them as items or as polygons.
| |
|
| |
|
| An example of a TQL query is <code>SELECT_LOTSIZE_WHERE_CATEGORY_IS_SOCIAL_AND_STAKEHOLDERTYPE_IS_MUNICIPALITY</code>. In this example, <code>SELECT_LOTSIZE</code> is the statement. <code>CATEGORY_IS_SOCIAL</code> is the first clause, and <code>STAKEHOLDERTYPE_IS_MUNICIPALITY</code> is the second clause. It would return all the land area taken up with social housing, which is also owned by a municipal stakeholder.

It would return all the land area taken up with social housing, which is also owned by a municipal stakeholder. |
|
| |
|
| Note that all clauses in a TQL query are cumulative. All clauses are connected by the term <code>AND</code>. This means all clauses must be met before the data is "counted". Depending on how you use TQL in your project or applications, it is possible to simulate an "OR" functionality as well (i.e. <code>CATEGORY_IS_SOCIAL</code> ''or'' <code>CATEGORY_IS_NORMAL</code>). This can be done simply by executing multiple queries, one for each "OR" section. | | Note that all clauses in a TQL query are cumulative. All clauses are connected by the term <code>AND</code>.

|
| ==Usage== | | ==TQL components== |
| TQL can be used in a number of places. The most common place is in the [[excel]]s of custom [[indicator]]s or [[panel]]s. To indicate which cells should contain certain data from the [[session]], cells in an excel file can be given a name. In this case, the name would be a TQL query. When an indicator calculation takes place, the {{software}} will obtain all queries that exist in the excel file of the indicator. For the queries with <code>SELECT</code> statements, the results of those queries are obtained and placed in the corresponding cells. when the calculation of the excel is complete, the cells with an <code>UPDATE</code> statement are read out, and the items in the project indicated by those queries are updated with those values. | | TQL queries are composed of 2 major elements: the [[#Statements|statement]], and the [[Clause (TQL)|clauses]]. Together they may make up a single query. |
|
| |
|
| 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 it's necessary to quickly check whether a certain type of data is present or correctly readable. The query tool also functions both in and out of [[Test Run|test runs]], allowing a user to also check data in a [[project]] during a session.
| | ===Statements=== |
| | Statements are the instruction which is to be performed with the [[Project]]. A query always has exactly one statement. |
|
| |
|
| It's also possible to execute TQL queries directly via the [[API]]. The advantage of using TQL, rather than inspecting a project's data via the API directly, is that it can be used to perform calculations that require some intermediate processing. For example, calculating the intersection of buildings with an area or neighborhood. Other examples of this include the queries related to values of [[grid overlay|grid]]s, or the multiplication of floor size with a related [[function values | function value]].
| | There are 2 kinds of [[TQL]] Statements: |
| | * [[Select (TQL)|Select statement]]s, for data retrieval from [[Item]]s in a [[Project]] |
| | * [[Update (TQL)|Update statement]]s, for writing data (back) into the [[Project]] and its [[Item]]s |
|
| |
|
| ==Statements== | | ===Clauses=== |
| Statements are the primary part of a query. They indicate what must be done with data in a [[session]]. Statements start with either <code>SELECT</code> or <code>UPDATE</code>. <code>SELECT</code> statements retrieve data from a [[session]]. <code>UPDATE</code> 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.
| | {{main|Clause (TQL)}} |
| | 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 <code>WHERE</code>. Multiple additional clauses can be added to a query using the phrase <code>AND</code>. 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. |
|
| |
|
| ===Polygon statements===
| | For any given [[Select (TQL)]] or [[Update (TQL)]] 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. |
| These <code>SELECT</code> statements interact with data as polygon data. This means that, depending on the clauses added to the query, they generally compute how much surface area in the world meets a certain set of conditions.
| |
|
| |
|
| ====Land polygons====
| | The order in which the clauses appear in the query is not relevant. |
| 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.

| ====Construction polygons==== | | ====Limiting Search Polygon==== |
| Construction polygon statements relate to surface area in use by [[construction]]s. These are mostly used for determining the amount of certain types of constructions, and their cumulative values.
| | Some clause parameters described on this wiki note that they ''Limit the Search Polygon''. The Search Polygon is the geometry created from the specified clauses that will limit the buildings that will be considered when executing the statement. For example <code>SELECT_LOTSIZE_WHERE_AREA_WITH_ATTRIBUTE_SPECIAL_CASE_AND_CATEGORY_IS_SOCIAL</code> will create a search polygon for buildings based on the areas that have the attribute <code>SPECIAL_CASE</code>. The [[Area with attribute (TQL Param)]] is a search polygon limiter. |

Ultimately, the statement returns the landsize of the limiting search polygon. |

| ====Distance==== | | ==Usage== |
| Distance statements are used to determine the distance between the central points of 2 specific polygons.
| | TQL can be used in a number of places. The most common place is in the [[excel]]s of custom [[indicator]]s, [[panel]] or [[global]]s. To indicate which cells should contain certain data from the [[session]], cells in an excel file can be given a name. In this case, the name would be a TQL query. When an indicator calculation takes place, the {{software}} will obtain all queries that exist in the excel file of the indicator. For the queries with <code>SELECT</code> statements, the results of those queries are obtained and placed in the corresponding cells. when the calculation of the excel is complete, the cells with an <code>UPDATE</code> statement are read out, and the items in the project indicated by those queries are updated with those values. |

| |
| Note that although the clauses are described as "intersecting", in the context of this statement the centers of the selected polygons are used.
| |
|
| |
|
| ===Item statements===
| | 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 it's necessary to quickly check whether a certain type of data is present or correctly readable. The query tool also functions both in and out of [[Test Run|test runs]], allowing a user to also check data in a [[project]] during a session. |
| These <code>SELECT</code> statements interact with data as item data. This means that, depending on the clauses added to the query, they retrieve a specific property or value related to a single component of a [[project]], such as an [[area]]'s [[attribute]], or the name of a [[stakeholder]].
| |
|
| |
|
| ====Numeric values====
| | It's also possible to execute TQL queries directly via the [[API]]. The advantage of using TQL, rather than inspecting a project's data via the API directly, is that it can be used to perform calculations that require some intermediate processing. For example, calculating the intersection of buildings with an area or neighborhood. Other examples of this include the queries related to values of [[grid overlay|grid]]s, or the multiplication of floor size with a related [[function values | function value]]. |
| Numeric value statements relate to [[attribute]]s and [[global]]s, 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 overlay]]s, and as parameters in user-ceated [[excel]] files for [[indicator]]s and [[panel]]s.

| ====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 [[indicator]]s and [[panel]]s 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 <code>SELECT_ATTRIBUTE_WHERE_NAME_IS_COLOR</code>. In these cases the color is returned as a numeric value. For more information on this value, see the [[attribute#COLOR|attribute]] article.

| |
| 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 [[stakeholder]]s.

| ===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 <code>WHERE</code>. Multiple additonal clauses can be added to a query using the phrase <code>AND</code>. 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.

| |
| | TIMEFRAME
| |
| | The grid data being considered must be data from this [[timeframe]] of the [[grid overlay|grid]] specifically.
| |
| | N/A
| |
| | Integer specifying the timeframe to use.
| |
| |}
| |
| The counting/naming of timeframes begins at 0. The first timeframe is "0", the second timeframe is "1", etc. If a grid has 20 timeframes, the last timeframe is "19". If the specified timeframe does not exist, or no timeframe is specified, the last timeframe of the grid is used. If a [[grid overlay]] does not have results in the form of multiple [[timeframe]]s, the overlay is considered to have exactly 1 timeframe.
| |
| | |
| 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 the GRIDVALUE clause requires an exact numerical match, making it appropriate only for situations where the grid can be expected to contain exact values, ideally integer values. Examples include the [[ Distance_Zone_(Overlay)|Distance zone overlay]] with the "Count hit" setting enabled, the [[Water Overlay]] with the IMPACTED_BUILDINGS result type, or the [[Average Overlay]].

| |
| | |
| ==Examples for common use-cases==
| |
| | |
| A number of use-cases come up frequently across various projects. Queries of the following forms often provide a firm basis for using TQL to obtain required data.
| |
| | |
| ====Function values (selecting)====
| |
| '''Parking requirements of social housing'''
| |
| | |
| The parking demand is based on a [[function values | function value]] of each function, and is defined as "parking places per m2". Parking demand is not based on the footprint of a construction, but the size of a construction. i.e. a construction 4 floors high needs more parking than a building with the same footprint 2 floors high.
| |
| | |
| <code>SELECT_FLOORSIZE_WHERE_CATEGORY_IS_SOCIAL_AND_CATEGORYMULT_IS_PARKING_LOTS_DEMAND_PER_M2</code>
| |
| | |
| * <code>SELECT_FLOORSIZE</code>: What we are basically looking for is the floorsize of the construction.
| |
| * <code>CATEGORY_IS_SOCIAL</code>: We only want to look at constructions which are of the [[Function Category|category]] social housing. For that, a category clause is added.
| |
| * <code>CATEGORYMULT_IS_PARKING_LOTS_DEMAND_PER_M2</code>: Lastly, we are not looking directly for the floorsize, but for the parking demand as a result of that floorsize.
| |
| | |
| ====Function values (updating)====
| |
| '''Traffic intensity on roads'''
| |
| | |
| The traffic intensity is a function value which affects calculations related to [[Traffic Model|traffic]]. Some use-cases require these values to be updated dynamically. This can be done per neighborhood. (In this example, the [[neighborhood]] in question has the ID 1.)
| |
| | |
| <code>UPDATE_BUILDING_TRAFFIC_FLOW_WHERE_CATEGORY_IS_ROAD_AND_NEIGHBORHOOD_IS_1</code>
| |
| | |
| * <code>UPDATE_BUILDING</code>: We're changing an attribute of a building.
| |
| * <code>TRAFFIC_FLOW</code>: The attribute we are changing is the TRAFFIC_FLOW, which is the technical name of a function value.
| |
| * <code>CATEGORY_IS_ROAD</code>: We only want to update this value on roads.
| |
| * <code>NEIGHBORHOOD_IS_1</code>: We are updating only in this specific neighborhood. Nothing outside the neighborhood is updated by this statement.
| |
| | |
| ====Grid average====
| |
| '''Quality of livability in a neighborhood'''
| |
| | |
| The [[livability (Overlay)|livability overlay]] calculates, for each [[grid overlay|grid cell]], the average livability. The best indication of how well a certain region performs in terms of livability would be to average these values out. That way, its possible to compare places which are not the same size. (In this example, the [[neighborhood]] in question has the ID 1, and the [[grid overlay|grid]] of [[livability (Overlay)|livability]] has the ID 4.)
| |
| | |
| <code>SELECT_GRIDAVG_WHERE_NEIGHBORHOOD_IS_1_AND_GRID_IS_4</code>
| |
| | |
| For any given neighborhood, different points of a [[grid overlay|grid]] may score differently.
| |
| | |
| * <code>SELECT_GRIDAVG</code>: We're looking for the average score across the entire neighborhood.
| |
| * <code>NEIGHBORHOOD_IS_1</code>: We don't need the average of the entire map, but only of a specific neighborhood.
| |
| * <code>GRID_IS_4</code>: We need to specify the grid we wish to use the values of.
| |
| | |
| ====Grid values====
| |
| '''The area of open water which is flooded by more than 20 cm of water'''
| |
|
| |
|
| The [[Rainfall (Overlay)|rainfall overlay]] calculates what amounts of water ends up where. The overlay's results are in meters. If we wish to provide some minimum value, it must be in meters as well. 20 cm is 0,2 meters. The [[3D world]] can also contain multiple types of [[terrain|water]]. All types of have one thing in common, namely that they all have the WATER attribute, which can be tested against. (In this example, the grid of [[Rainfall (Overlay)|inundation]] has the ID 4, and has its result type set to water stress.)
