DBCC MEMORYSTATUS
Return a lot of data about the memory st5atus in the SQL Server.
Get details of all of the queries here:
Get all constraints of a specific type
select *
from information_schema.table_
where CONSTRAINT_TYPE = 'UNIQUE'
-- 'CHECK' , 'UNIQUE' , 'PRIMARY KEY' , 'FOREIGN KEY'
Get Constraints details include columns
select t.TABLE_SCHEMA, t.TABLE_NAME,

c.COLUMN_NAME
from information_schema.table_
join information_schema.constraint_column_usage c
on t.Constraint_Name = c.Constraint_Name
--where t.CONSTRAINT_NAME = 'UC_Something'
--where t.CONSTRAINT_TYPE = 'Unique'
--where t.TABLE_NAME = 'TableName'

This query return the scheduling's of jobs in the server.
Jobs without scheduling won't be return (unless you change the query to LEFT JOINs) – in order to get the scheduling mapping in the server.

An item with the same key has already been added
Error when try to open an alert properties:
An item with the same key has already been added. (mscorlib)
Cause: There are 2 (or more) jobs with the same name.
Find the duplicated names of jobs using this query:
select name, count(*) from msdb.dbo.sysjobs
group by name having count(*) > 1
Fix: Rename or delete one of the jobs with the duplicate name.
* Alerts can be executed by jobs, so maybe it caused an error when try to find this connection between alerts and jobs.
