Find the Number of Rows in Database Tables

Had a need to track empty tables in a DB to see if converted systems were correctly hooked up and wanted to add filters.Sorry I didn't keep the link to the original website.

SELECT
QUOTENAME(SCHEMA_NAME(sOBJ.schema_id)) + '.' + QUOTENAME(sOBJ.name) AS [TableName]
, SUM(sdmvPTNS.row_count) AS [RowCount]
FROM sys.objects AS sOBJ
INNER JOIN sys.dm_db_partition_stats AS sdmvPTNS
ON sOBJ.object_id = sdmvPTNS.object_id
WHERE 
      sOBJ.type = 'U'
      AND sOBJ.is_ms_shipped = 0x0
      AND sdmvPTNS.index_id < 2
--Find all by schema
-- AND SCHEMA_NAME(sOBJ.schema_id) = ''
GROUP BY
      sOBJ.schema_id
      , sOBJ.name
--Only find empty tables
--HAVING SUM(sdmvPTNS.row_count) = 0
ORDER BY [TableName]
, [RowCount];

Add Log Percent Used Alert to all non System DBs

in my never ending quest to automate more monitoring I have added this to my pre-production deployment package. It assumes a Operator group of the name DBgroup has been created to transmit the alerts.
Also Database Mail must be set up on the agent.

USE [msdb]
GO

DECLARE @RemoveExisting as bit = 1; --Set to 1 to purge any existing

DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.sys.databases
WHERE name NOT IN ('model','master', 'msdb','tempdb')

DECLARE @DBname nvarchar(max) = '';
DECLARE @AlertName nvarchar(max) = '';
DECLARE @AlertText nvarchar(max) = '';

OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @DBname

WHILE @@FETCH_STATUS = 0
BEGIN
SET @AlertName = @DBname  + N'_LogPercentUsed';
SET @AlertText = N'Databases|Percent Log Used|' + @DBname + '|>|90';

IF EXISTS(select id from sysalerts where name = @AlertName) AND  @RemoveExisting = 1
EXEC msdb.dbo.sp_delete_alert @AlertName;

IF NOT EXISTS(select id from sysalerts where name = @AlertName)
BEGIN
EXEC msdb.dbo.sp_add_alert @name= @AlertName ,
@message_id=0,
@severity=0,
@enabled=1,
@delay_between_responses=1715,
@include_event_description_in=1,
@category_name=N'[Uncategorized]',
@performance_condition= @AlertText
, @job_id=N'00000000-0000-0000-0000-000000000000';

EXEC msdb.dbo.sp_add_notification @alert_name= @AlertName, @operator_name=N'DBGroup', @notification_method = 1;

END

  FETCH NEXT FROM db_cursor INTO @DBname
END

CLOSE db_cursor
DEALLOCATE db_cursor

Monitor Job Satus through script

Had a need to verify prerequisite site had run prior to downstream asynchronous jobs so I found and modified a couple queries.

@IsSuccessful - Whether or not any jobs meet the criteria
To fine all failed jobs put 0

RETURNS

Yet a more improve bulk DB set up file

This on attempt to do more and protect the system DBs

This script will:
1. Change the DB owner
2. Set all to simple mode. Cannot figure out how to stop the tempdb message
3. Set all DBs to 2012 mode
4. Add the domain users as owners. Please use this as a prototype for other test and dev users
5. Shrink all logs to 500 MB to ensure there is plenty of space

Left to do standardize file growths, block create user when the user exists

GO


DECLARE @prefix nvarchar(120) = 'IF ''?'' NOT IN(''master'', ''model'', ''msdb'', ''tempdb'') BEGIN  ';
DECLARE @postfix nvarchar(50) = ' END';

SQL Connection Error: "The target principal name is incorrect. Cannot generate SSPI context"

Welcome to the rabbit hole.

This can be caused when there are more than one entry for a SQL Server entry in Kerberos. Sometimes it is caused when a SQL Server is installed under one domain user and is then is switch to another.

Technet article: How to troubleshoot the "Cannot generate SSPI context" error message
https://support.microsoft.com/en-us/kb/811889?wa=wsignin1.0 

Really good description but no examples:
How Windows Server 2012 Eases the Pain of Kerberos Constrained Delegation, Part 2

Basically you delete the existing entries and make new ones. You have to be an AD admin to make the deletions.

Commands of use:

C:>ipconfig /flushdns

C:>ipconfig /renew

Adding Bulk Rights SQL 2005

Was trying to do some quick administration and realized the SQL Server 2005 had a different method than 2012. Do not put any [] brackets in the user name. However, make sure you put brackets around the DB name especially with Sharepoint to handle the dashed in the DB name.
