Some of the common queries that can be used against the content database:
-- Query to get all the top level site collections
SELECT SiteId AS SiteGuid, Id AS WebGuid, FullUrl AS Url, Title, Author, TimeCreated
FROM dbo.Webs
WHERE (ParentWebId IS NULL)

-- Query to get all the child sites in a site collection
SELECT SiteId AS SiteGuid, Id AS WebGuid, FullUrl AS Url, Title, Author, TimeCreated
FROM dbo.Webs
WHERE (NOT (ParentWebId IS NULL))

-- Query to get all the SharePoint groups in a site collection
SELECT dbo.Webs.SiteId, dbo.Webs.Id, dbo.Webs.FullUrl, dbo.Webs.Title, dbo.Groups.ID AS Expr1,
dbo.Groups.Title AS Expr2, dbo.Groups.Description
FROM dbo.Groups INNER JOIN
dbo.Webs ON dbo.Groups.SiteId = dbo.Webs.SiteId

-- Query to get all the users in a site collection
SELECT dbo.Webs.SiteId, dbo.Webs.Id, dbo.Webs.FullUrl, dbo.Webs.Title, dbo.UserInfo.tp_ID,
dbo.UserInfo.tp_DomainGroup, dbo.UserInfo.tp_SiteAdmin, dbo.UserInfo.tp_Title, dbo.UserInfo.tp_Email
FROM dbo.UserInfo INNER JOIN
dbo.Webs ON dbo.UserInfo.tp_SiteID = dbo.Webs.SiteId
-- Query to get all the members of the SharePoint Groups
SELECT dbo.Groups.ID, dbo.Groups.Title, dbo.UserInfo.tp_Title, dbo.UserInfo.tp_Login
FROM dbo.GroupMembership INNER JOIN
dbo.Groups ON dbo.GroupMembership.SiteId = dbo.Groups.SiteId INNER JOIN
dbo.UserInfo ON dbo.GroupMembership.MemberId = dbo.UserInfo.tp_ID
-- Query to get all the sites where a specific feature is activated
SELECT dbo.Webs.Id AS WebGuid, dbo.Webs.Title AS WebTitle, dbo.Webs.FullUrl AS WebUrl, dbo.Features.FeatureId,
dbo.Features.TimeActivated
FROM dbo.Features INNER JOIN
dbo.Webs ON dbo.Features.SiteId = dbo.Webs.SiteId AND dbo.Features.WebId = dbo.Webs.Id
WHERE (dbo.Features.FeatureId = '00BFEA71-D1CE-42de-9C63-A44004CE0104')

-- Query to get all the users assigned to roles
SELECT dbo.Webs.Id, dbo.Webs.Title, dbo.Webs.FullUrl, dbo.Roles.RoleId, dbo.Roles.Title AS RoleTitle,
dbo.UserInfo.tp_Title, dbo.UserInfo.tp_Login
FROM dbo.RoleAssignment INNER JOIN
dbo.Roles ON dbo.RoleAssignment.SiteId = dbo.Roles.SiteId AND
dbo.RoleAssignment.RoleId = dbo.Roles.RoleId INNER JOIN
dbo.Webs ON dbo.Roles.SiteId = dbo.Webs.SiteId AND dbo.Roles.WebId = dbo.Webs.Id INNER JOIN
dbo.UserInfo ON dbo.RoleAssignment.PrincipalId = dbo.UserInfo.tp_ID

-- Query to get all the SharePoint groups assigned to roles
SELECT dbo.Webs.Id, dbo.Webs.Title, dbo.Webs.FullUrl, dbo.Roles.RoleId, dbo.Roles.Title AS RoleTitle,
dbo.Groups.Title AS GroupName
FROM dbo.RoleAssignment INNER JOIN
dbo.Roles ON dbo.RoleAssignment.SiteId = dbo.Roles.SiteId AND
dbo.RoleAssignment.RoleId = dbo.Roles.RoleId INNER JOIN
dbo.Webs ON dbo.Roles.SiteId = dbo.Webs.SiteId AND dbo.Roles.WebId = dbo.Webs.Id INNER JOIN dbo.Groups ON dbo.RoleAssignment.SiteId = dbo.Groups.SiteId AND
dbo.RoleAssignment.PrincipalId = dbo.Groups.ID

-- Query to get all Files by date

SELECT AllLists.tp_Title AS 'List Name',

AllDocs.LeafName AS 'File Name',

AllDocs.[TimeLastModified] AS 'TimeLastModified',

AllDocs.DirName AS 'URL'

FROM AllDocs 

JOIN AllLists 

ON AllLists.tp_id = AllDocs.ListId WHERE AllDocs.[TimeLastModified]>='2012-01-01' AND AllDocs.Type <> 1 AND (LeafName NOT LIKE '%.stp') AND (LeafName NOT LIKE '%.aspx') AND (LeafName NOT LIKE '%.xfp') AND (LeafName NOT LIKE '%.dwp') AND (LeafName NOT LIKE '%template%') AND (LeafName NOT LIKE '%.inf') AND (LeafName NOT LIKE '%.css')
