Create a list of all FK's with a comma delimited list of columns in SQL Server

Running the query below will create a list of all Foreign Keys and a comma delimited list off all the fields in the relationship.  You'll want to be in the database (i.e. use a "use database" statement).

select t.name as parent_table,

c.name as child_table,

fk.name as foreign_key,

      STUFF(( SELECT  ','+ col.name

            FROM sys.columns col

            inner join sys.foreign_key_columns fkc on fkc.parent_object_id = col.object_id and fkc.parent_column_id = col.column_id

            WHERE col.object_id = t.object_id

            FOR XML PATH('')),1 ,1, '')  as foreign_key_fields

from sys.objects o

inner join sys.objects t on t.object_id = o.parent_object_id

inner join sys.foreign_keys fk on o.object_id = fk.object_id

inner join sys.objects c on fk.referenced_object_id = c.object_id

group by t.name, c.name, fk.name, t.object_id

order by fk.name

Query to Get Line Count of a Stored Procedure in SQL Server

The query below will return a programming object along with the number of carriage returns which exist within it.

select t.sp_name, sum(t.lines) - 1 as lines_of_code, type

from

      (select o.name as sp_name, o.type,

    (len(c.text) - len(replace(c.text, char(10), ''))) as lines

    from sysobjects o

    inner join syscomments c on c.id = o.id

    where o.type not in ('c', 'd')) t

group by t.sp_name, type

Get a cascading list of all tables that have a foreign key to a table or any of its dependencies

Disable all snapshots on a distributor

When creating replication from script I find that the snapshot agents are enabled and scheduled to run on the hour.  To prevent them from pounding the database and running you need to disable them.  If you have a lot of snapshot agents disabling them all through the GUI can take a long time.  The script below will disable all snapshot agents.


declare @sql nvarchar(1000)

declare curs cursor for
select 'EXEC msdb.dbo.sp_update_job @job_id=N''' + cast(job_id as varchar(100)) + ''', @enabled=0'
from msdb.dbo.sysjobs where date_created > '12/03/2013' and enabled = 1 and category_id = 15 --snapshot'

open curs

fetch next from curs into @sql

while @@FETCH_STATUS = 0
begin
print @sql

exec sp_executesql @sql

fetch next from curs into @sql
end

close curs

deallocate curs

Cleaning up a replicated database following a restore.

If you ever receive the error: "Cannot truncate table 'TABLENAME' because it is published for replication or enabled for Change Data Capture." but your database is not set up for replication it could be that the individual tables still think they're being replicated.  To see if this is the case run this query:
select * from sys.objects where is_published = 1
If you get any results then those tables think they are replicated.  To remove this replication run:
exec sp_removedbreplication 'DATABASENAME'
Warning!!  Verify you actually want to remove replication before doing this, once its gone it's gone and you'll need to resync.

I've noticed this behavior on occassion after backup up a replicated database and restoring it.  The restored version still has these flags set.

Cheers.
