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
|
SELECT is the most complex statement in SQL, with optional keywords and clauses that include:
