G Torq ALTA B2O 270	Posted - 2013.12.10 14:37:00 - [1] - Quote Introduction The following is meant as a primer for the Dust SDE, and how to use it for some basic operations, as being written by myself, and others from the #dust-dev channel. The SDE is provided as a single file, which is an SQLite3 database, that can either be used directly, or trivially converted for use on another platform. For browsing it easily, the program SQLiteSpy can be used. These posts will also contain some sample SQL, that should work directly with SQLite3. Structure of Catma The provided data represents a set of Dust classes (or types of objects/data) used in the game, with each Object belonging to 1 class (with some exceptions). The classes included are: ActiveSkillGainBooster - Active SP Boosters AttributeData - Listing of all Attributes AttributeDescriptor - Display Hints for Attributes DamageType - Damage Types DustHealingActor - Supply depot healing attributes DustModule - Every module/equipment/weapon DustOMSOrbitalStrike - Orbital Strikes DustPawn - Dropsuits ExplosionContent - Explosion types FactionBoosterAmarr - LP Boosters, Amarr FactionBoosterCaldari - LP Boosters, Caldari FactionBoosterGallente - LP Boosters, Gallente FactionBoosterMinmatar - LP Boosters, Minmatar InstallationContent - All installations InventoryCategory - Market Grouping ModifierDeclaration - Various attribute modifiers PassiveSkillGainBooster - Passive SP Boosters ProjectileContent - All Projectiles Tag - Tags TurretWeaponContent - Turret weapons (not turrets) VehicleContent - All vehicles The data is provided in 3 tables, which describes the type and class of the data, and the attributes: CatmaAttributes - Attributes CatmaClasses - The class of every object CatmaTypes - The specific typeName of each object Every object and class in the system is identified by a "typeID" value, a number that uniquely identifies it. CatmaClasses The CatmaClasses table consists of 2 columns: typeID - the typeID for an object className - the name of the class that object belongs to To locate e.g. all suits, you can first get a list of all objects (all typeIDs) of the class "DustPawn" from CatmaClasses, and then retrieve any relevant attributes from CatmaAttributes. CatmaTypes The CatmaTypes table consists of 2 columns: typeID - the typeID of an object typeName - the specific typeName of that object Most, if not all objects and classes in the system have a typeName associated with it, and the typeName is structured such that objects of a given kind have similar typeNames. CatmaAttributes The CatmaAttributes table consists of 5 columns: typeID - typeID of an object catmaAttributeName - name of an attribute catmaValueInt - integer (whole number) value catmaValueFloat - float (decimal number) value catmaValueText - text value Any catmaAttributeName will only use 1 of the three catmaValue* fields, and it cannot immediately be determined from the data which to use. You will basically need to look at your data and see what field to use for any catmaAttributeName. (more when written ...) Team Fairy DUST

Steve Renuken Guardian Solutions DARKSTAR ARMY 36	Posted - 2013.12.12 11:21:00 - [10] - Quote If you're ever unsure of the type you'll be getting back, the following snippet is of use, if you're using the mysql version I provide. The sqlite version doesn't support it, due to a lack of nulls in the DB at present. coalesce(catmaValueInt,catmaValueReal,catmaValueText) value

I tried and thought I did some research that said SQLite just doesn't have coalesce. Any idea how to insert null values in SQLite3? I couldn't really find a way but that may be my Google Fuu being terrible. CCP FoxFour // Game Designer // Team True Grit http://twitter.com/regnerba

Absolute Idiom II SyNergy Gaming EoN. 920	Posted - 2013.12.12 12:15:00 - [12] - Quote Maybe you declared the columns as 'NOT NULL' when you created the database? If so, then the table will not accept null values. Fanfest 2012 - Winning Team + MVP - £1100 in prizes Fanfest 2013 - Winning Team - £500 in prizes Fanfest 2014 - ???

I couldn't really find a way but that may be my Google Fuu being terrible. Turns out sqlite can support nulls. running: update catmaattributes set catmavalueint=null where catmavalueint='None'; using the sqlite3 command line that's on my linux box works a treat. As for how you'd set them, that's going to be highly dependant on the software you're using to work with the database, I'd suspect.
