T-SQL User Mapping

Question

 I need to get a list of users and databases that a sql login is mapped to.  Is there a view or a sp that can get me this information?

You can use as a procedure:
Code Snippet
if exists (select 1 from sysobjects where name like '%sp_logins_database%')
drop proc sp_logins_database
go
create procedure sp_logins_database @db sysname = null
as
declare @cmd varchar(200),@database sysname
if exists (select 1 from tempdb..sysobjects where name like '%#logins_users%')
drop table #logins_users
create table #logins_users
(database_name varchar(100),
username varchar(100),
loginname varchar(100))
declare cur cursor for
select name from master..sysdatabases
open cur
fetch next from cur into @database
WHILE @@FETCH_STATUS = 0
begin
set @cmd = 'select '''+@database+''', l.loginname as [login name],u.name as [user name] from '+@database+'..sysusers u inner join master..syslogins l
on u.sid=l.sid'
insert into #logins_users
exec (@cmd)
fetch next from cur into @database
end
close cur
deallocate cur
if @db is null
select * from #logins_users
order by database_name
if @db is not null
select * from #logins_users
where database_name = @db
order by database_name
go
exec sp_logins_database 'master'
