Useful SQL snippets
Introduction
These SQL queries are intended to be fast and easy-to-use tools to help identify and troubleshoot problems in the AzerothCore database. They're here to be a quick reference to help when looking at DB-related problems.
Loot and Reference Loot Issues
Find what creatures drop an item directly
Note that this doesn't count items dropped from RLTs.
SET @ITEMID := XXXX;
SELECT ct.name, clt.chance, ct.maxlevel, it.ItemLevel
FROM `creature_template` ct
JOIN `creature_loot_template` clt ON ct.lootid = clt.entry
JOIN `item_template` it ON clt.item = it.entry
WHERE it.entry = @ITEMID;
Find which RLTs an item is in
SET @ITEMID = XXXX;
SELECT rlt.entry, it.name
FROM `reference_loot_template` rlt
JOIN `item_template` it ON rlt.Item = it.entry
WHERE rlt.item = @ITEMID;
Find which creatures share a RLT
Non-recursive.
SET @RLTENTRY := XXXX;
SELECT distinct ct.entry, ct.name
FROM `creature_template` ct
JOIN `creature_loot_template` clt ON ct.lootid = clt.entry
WHERE clt.Reference = @RLTENTRY;
Find a number of items and level statistics for items in a given RLT
This is useful when determining which creatures should have a particular RLT in their drop tables.
SET @RLTENTRY := XXXX;
SELECT COUNT(rlt.Item), MIN(it.ItemLevel), MAX(it.ItemLevel), AVG(it.ItemLevel)
FROM `item_template` it
JOIN `reference_loot_template` rlt ON it.entry = rlt.item
WHERE rlt.entry = @RLTENTRY;
Recursively find an item by name
Note this is complex enough that Keira won't run it properly - you must run it from a MySQL command prompt. Thanks to @anguaive for this one.
SET @ITEM_NAME := 'insert name of item here';
SET @ITEM_ID := (SELECT `entry` FROM `item_template` WHERE `name` = @ITEM_NAME);
SELECT DISTINCT ct.name AS `creature`, @ITEM_NAME as `item` FROM (
WITH RECURSIVE cte (`entry`, `item`, `reference`) AS (
SELECT `entry`, `item`, `reference`
FROM `reference_loot_template`
WHERE `item` = @ITEM_ID
UNION ALL
SELECT r.entry, r.item, r.reference
FROM `reference_loot_template` r
INNER JOIN cte
ON r.reference = cte.entry
)
SELECT clt.entry
FROM cte
JOIN `creature_loot_template` clt ON clt.reference = cte.entry
UNION ALL
SELECT entry
FROM
`creature_loot_template`
WHERE item = @ITEM_ID
) AS q
JOIN `creature_template` ct ON ct.lootid = q.entry
ORDER BY ct.name;
Miscellaneous Issues
Find creature information from a spawn GUID
Bug reports sometimes just reference a GUID with no other information about an NPC. This will find the creature a GUID belongs to.
SET @CGUID := XXXX;
SELECT ct.entry, ct.name, ct.minlevel, ct.maxlevel
FROM `creature_template` ct
JOIN `creature` c ON ct.entry = c.id
WHERE c.guid = @CGUID;
Find all static creatures given a name
You could use part of the NPC's name (as here, 'Gordunni') and it will find all NPCs with that string in their name.
SET @NAME := 'gordunni';
SELECT c.guid, ct.name
FROM `creature` c
JOIN `creature_template` ct ON ct.entry = c.id
WHERE c.movementtype = 0 AND ct.name LIKE '%@NAME%';
Find creatures that use a certain spell
Note that this is a bit rough and ready, and only works if the spell is in their first action slot. In this case, XXXX is the spell ID.
SET @SPELLID := XXXX;
SELECT ct.entry, ct.name, ct.maxlevel, ss.action_param1
FROM `creature_template` ct
JOIN `smart_scripts` ss ON ct.entry = ss.entryorguid
WHERE ss.action_param1 = @SPELLID;
Find the average wander distance for a creature
Could be used for fixing static creatures.
SET @CID := XXXX;
SELECT c.id, AVG(c.wander_distance)
FROM `creature` c
WHERE c.id = @CID AND c.wander_distance > 0;
Find other members of a node pool
Given a node GUID, find if it belongs to a node pool and list the other members.
SET @GUID := XXXX;
SELECT * FROM `pool_gameobject` WHERE `pool_entry` IN (
SELECT `pool_entry` from `pool_gameobject` WHERE guid = @GUID);
Find respawn timers for a class of object
Given an object's name, find the respawn timers for all spawns that match that name string.
SELECT got.name, go.guid, go.spawntimesecs
FROM `gameobject_template` got
JOIN `gameobject` go ON got.entry = go.id
WHERE name LIKE '%name-of-object%'
ORDER BY go.spawntimesecs
List items inside the inventory based on character GUID
Given a character GUID, show the inventory with the according count inside the item instance and the according name inside the item template.
SET @GUID := XXXX;
SELECT ci.*, ii.itemEntry, it.name, ii.count
FROM character_inventory ci
JOIN item_instance ii ON ci.item = ii.guid
JOIN acore_world.item_template it ON ii.itemEntry = it.entry
WHERE ci.guid = @GUID;
