TQL

The Tygron Query Language is a special-purpose programming language designed for obtaining spacial area information from a specific game session on the Tygron Engine. The primary reason for its development was to make an easy to use bridge between the Tygron Engine and Microsoft Excel.

Queries

The operation used in TQL is the query, which is performed with the declarative SELECT statement. SELECT retrieves data from a running Tygron game session. The SELECT statements have no persistent effects on the game session itself.

Queries allow the user to describe desired data, leaving the Tygron Engine responsible for planning, optimizing, and performing the physical operations necessary to produce that result as it chooses.

A query includes a parameter to include in the final result, immediately following the SELECT keyword. Currently, one of the following result parameters can be chosen:

Result Parameter	Description	Example
FLOORSIZE	Floor size of buildings.	SELECT_FLOORSIZE_WHERE_CATEGORY_IS_OFFICES
LOTSIZE	Lot size of buildings.	SELECT_LOTSIZE_WHERE_CATEGORY_IS_OFFICES
UNITS	Amount of housing units.	SELECT_UNITS_WHERE_CATEGORY_IS_SOCIAL
DIKES	Surface space of constructed dikes or levees.	SELECT_DIKES_WHERE_ZONE_IS_1

Comparison Predicate

The SELECT and result parameter are followed by the WHERE statement. The WHERE statements includes a comparison predicate, which restricts the information taken into account by the query. The WHERE clause eliminates all information from the result set where the comparison predicate does not evaluate to True.

The comparison predicate consists of 0 or more clauses. Clauses consists of three parts;

• Clause Type
• Operator
• Value

Clauses

The clause types and expected values currently supported are:

Clause Type	Description	Value Type	Example
CATEGORY	A construction belongs to the specific Function category	Function category	CATEGORY_IS_INDUSTRY
FUNCTION	A construction belongs to a specific Function	Function ID	FUNCTION_IS_621
DIKE	A construction is constructed or planned on top of a particular type of Dike (or Levee)	Dike ID	DIKE_IS_0
MAP	A construction is present in the specified map or view. Also see Simulation Type	CURRENT or MAQUETTE	MAP_IS_MAQUETTE
STAKEHOLDER	A construction is owned by a specific Stakeholder	Stakeholder ID	STAKEHOLDER_IS_7
STAKEHOLDERTYPE	A construction is owned by stakeholders of a specific Stakeholder Type	Stakeholder Type	STAKEHOLDERTYPE_IS_COMPANY
MAP	A buildings belongs to the specified Function category	Function category	Function category
MAP	A buildings belongs to the specified Function category	Function category	Function category

Operators

TQL clausses currently support the following Operators:

Operator	Description	Example
IS	Equal to	CATEGORY_IS_OFFICES

Simulation Type

Depending on the Simulation Type, the map parameter is named as followed in the Query Tool:

Simulation Type	CURRENT	MAQUETTE
Planning	ORIGINAL	PLANNED
Timeline	TODAY	MODEL
