DBA On The Go

I've been working in Enterprise IT environments for roughly 10 years. My move to become a DBA was new, but expected. I've worked in secure DoD databases and secure Pharmaceutical databases. One thing to note, the security aspect isn't a lot different. My goal is to marry Databases and security in a functional manner and see how we can speed these things up with minimal work.

Forcing Results To Conform For Exports

This one is a bit off for me. I've had to make SSIS exports kick out in specific ways such as how a number is returned or how many spaces a column returned every time regardless of how long the actual return was. Here's a few things I've put in use that seemed to work out well in this situation. If you all have any others I don't have here that are more common or a better fit, I'm always interested adding something new to my list of tools.

Two of these were created by Igor Nikiforov. They are included at the bottom of this page. They need to be added before this script will work. If you take nothing else from this post, please visit Igor's page and look at a few of his User Defined Functions. These are very useful if you're background isn't strong into coding. 

The original query is a simple select from adventure works. 

select 
addressid, addressline1, addressline2, city, StateProvinceID, postalcode, modifieddate 
from AdventureWorks2012.Person.Address

These are a few of the conversions we used to get the outputs to fit as we needed to match an older method. 

select 
 dbo.padl(addressid,10,'0') as AddressID 
,left(addressline1 + space (40),40) as AddressLine1
,Case when addressline2 is null then '' else addressline2 end as AddressLine2 
,isnull(city,'No City Listed') as City
,dbo.padl(StateProvinceID,3,'0') as StateProvinceID 
,dbo.padr(convert(char(15),postalcode), 15, ' ') as ZipCode 
,convert(varchar,ModifiedDate,110) as Date 
,convert(varchar,ModifiedDate,108) as Time 
from AdventureWorks2012.Person.Address 
order by convert(varchar,ModifiedDate,112) desc, convert(varchar,ModifiedDate,108) desc
