Code Snipets

A collection of code snippets as reference for various projects.  For SQL queries, I prefer mySQL only because it's easy to stick to one standard.

Blueprint Queries

Decryptors and their attributes:
SELECT invTypes.typeID, invTypes.typeName, invTypes.groupID,
GROUP_CONCAT(IF(attr.attributeID = 1112,coalesce(attr.valueInt,attr.valueFloat),NULL)) as `Success Modifier`,
GROUP_CONCAT(IF(attr.attributeID = 1113,coalesce(attr.valueInt,attr.valueFloat),NULL)) as `ME Modifier`,
GROUP_CONCAT(IF(attr.attributeID = 1114,coalesce(attr.valueInt,attr.valueFloat),NULL)) as `PE Modifier`,
GROUP_CONCAT(IF(attr.attributeID = 1124,coalesce(attr.valueInt,attr.valueFloat),NULL)) as `Runs Modifier(+)`
FROM invTypes
LEFT JOIN dgmtypeattributes attr ON attr.typeID=invTypes.typeID
WHERE (attr.attributeID =1112 OR attr.attributeID =1113 OR attr.attributeID =1114 OR attr.attributeID =1124)
-- attributeID: 1112=probabilityMod 1113=MEmod 1114=PEmod 1124=Runsmod
AND (invTypes.groupID >=728 AND invTypes.groupID <=731
-- Decryptor groups: 728=Amarr, 729=Minmatar, 730=Gallente, 731=Caldari
GROUP BY invTypes.typeID

@Fuzzysteve queries:

Querying Map Data

Gathering system data
SELECT region.regionName,constellation.constellationName,system.solarSystemName,
FROM mapsolarsystems system
JOIN mapregions region ON region.regionID = system.regionID
JOIN mapconstellations constellation ON constellation.constellationID=system.constellationID

Note: this includes both K-Space and W-Space.  To filter K-space/W-space:
WHERE region.regionName NOT LIKE '_-R00%' --Filter out w-space region names
WHERE <> -0.99 --All W-space systems have -0.99 security value

Query used to set up moon-map table
SELECT system.solarSystemName AS "system", region.regionName,system.x,system.y,system.z,,
SUM(IF(moonMaterial='Atmospheric Gases',1,0)) AS `Atmospheric Gasses`,
SUM(IF(moonMaterial='Cadmium',1,0)) AS Cadmium,
SUM(IF(moonMaterial='Ceasium',1,0)) AS Ceasium,
SUM(IF(moonMaterial='Chromium',1,0)) AS Chromium,
SUM(IF(moonMaterial='Cobalt',1,0)) AS Cobalt,
SUM(IF(moonMaterial='Dysprosium',1,0)) AS Dysprosium,
SUM(IF(moonMaterial='Hafnium',1,0)) AS Hafnium,
SUM(IF(moonMaterial='Hydrocarbons',1,0)) AS Hydrocarbons,
SUM(IF(moonMaterial='Mercury',1,0)) AS Mercury,
SUM(IF(moonMaterial='Neodymium',1,0)) AS Neodymium,
SUM(IF(moonMaterial='Platinum',1,0)) AS Platinum,
SUM(IF(moonMaterial='Promethium',1,0)) AS Promethium,
SUM(IF(moonMaterial='Scandium',1,0)) AS Scandium,
SUM(IF(moonMaterial='Silicates',1,0)) AS Silicates,
SUM(IF(moonMaterial='Technetium',1,0)) AS Technetium,
SUM(IF(moonMaterial='Thulium',1,0)) AS Thulium,
SUM(IF(moonMaterial='Tungsten',1,0)) AS Tungsten,
SUM(IF(moonMaterial='Titanium',1,0)) AS Titanium,
SUM(IF(moonMaterial='Vanadium',1,0)) AS Vanadium

FROM mapsolarsystems system

LEFT JOIN mapregions region ON system.regionID=region.regionID
LEFT JOIN moonData moons ON system.solarSystemName=moons.SOLARSYSTEMNAME
WHERE <= 0.4 AND <> -0.99 

GROUP BY system.solarSystemName

Technically, any GROUP BY can be used to build custom queries.  I like system.systemName or region.regionName

Note: 2D map uses (X,Z) coordinates, not (X,Y)
