Tricks of the Trade
PowerShell SQLCMD DOSDynamic SQL
and Concatenation
Agent Jobs
7

PowerShell
A must have for Windows tasks
You can’t automate Azure
without it
SQL PS has some limitations
8
EMBARCADERO TECHNOLOGIES
SQLCMD
Command Line interface to SQL Server
Very, very powerful
Can integrate with SQL Agent or Windows Scheduler
9

DOS
DOS is still alive
Mainly because I haven’t ported all
of my code to PowerShell
Can still be useful—especially
if on older Windows releases

Dynamic SQL and Concatantion
11
--Create the files
WHILE @number_of_files > 0BEGINif @number_of_files = 1 -- main tempdb file, move and re-sizeBEGINSELECT @sql_statement = 'ALTER DATABASE tempdb MODIFY FILE (NAME = tempdev, SIZE = '+convert(nvarchar(25), @individ_file_size) + ', filename = '+nCHAR(39)+@data_file_path+'tempdb.mdf'+nCHAR(39)+',MAXSIZE = '+ convert(nvarchar(25),@individ_file_size) + ', FILEGROWTH = 100MB);';ENDELSE -- numbered tempdb file, add and re-sizeBEGINSELECT @sql_statement = 'ALTER DATABASE tempdb ADD FILE (NAME = tempdev0' + convert(nvarchar(25),@number_of_files)+',filename = '+nCHAR(39)+@data_file_path+'tempdb0' + convert(nvarchar(25),@number_of_files)+'.ndf'+nCHAR(39)+', SIZE = '+ convert(varchar(25), @individ_file_size) + ', MAXSIZE = '+ convert(nvarchar(25), @individ_file_size) + ', FILEGROWTH = 100MB);';END
EXEC sp_executesql @statement=@Sql_StatementPRINT @sql_statement

Agent Jobs
Use the Scheduler
More than jobs—alterting and notifications
Regular Data Collection and Automation

Now You Have the Tools
13
Let’s Build Something Cool
EMBARCADERO TECHNOLOGIES
Demo--SQL Server Install and Best Practices
Default SQL Servers installs are a bad thing
Every time someone leaves cost threshold for parellelism at 5, a kitten dies
Let’s fix this..
14
EMBARCADERO TECHNOLOGIES
Demo--SQLCMD Dynamic SQL for Backups
This is a simple demo of the combination of some dynamic SQL and SQLCMD
Just an example—still schedule as an agent job
Or just use Ola’s script
15
EMBARCADERO TECHNOLOGIES
Demo--Patching SQL Server
Will use a combination of commands and PowerShell for CU automation
Use PowerShell to verify patch successful and notify admin
16
EMBARCADERO TECHNOLOGIES
Demo—Availability Groups DB Add
Complex example of T-SQL automation
Some interesting techniques
17
EMBARCADERO TECHNOLOGIES
Automation
With these tools the only limits are your imagination
Any repetitive tasks can and should be automated
Take advantage of scripting tools
Test, Test, Test and Test some more
18

Summary
I didn’t say DevOps—but this is kind of what DevOps is like
Automation makes you a better DBA—you can focus on value added activities like query tuning
Start small (installations) and build your skills to advanced techniques like patching and code deployments
