It can equally be applied to software purchases, developing software, developing databases, buying hardware etc...

DOSsing around

Having just finished a command line scripting system, here are the bookmarks/ techniques I used.
I can't share it here, but I'm quite proud of the finished result, which allows me to recursively execute folders of .sql files and update a central table of which patches have been applied.

DOS Commands & Batch files
A little DOS for a poor DBA

DOS String Manipulation

DOS FOR command

File name parsing in batch file and more idioms

Loop files in a directory with a batch file

Executing a folder of sql scripts

for /r . %f in (*.sql) do @echo %f

for %i in (*.*) do echo %~ni

NB : You need to change "%i" to "%%i" for use inside a batch file.

Adding SQL ...

osql is command line tool from SQL 2000. Replaced by SQLCMD in SQL 2005+ and scheduled for deprecation but is still present.

osql -S{server} -d{database} -U{user} -P{password} -f 65001 -n -i{filename} -b

Running XP in Virtualbox

To run Windows XP efficiently on Virtualbox...
  • Use 1 core
  • Disable PAE/NX

  • Disable IO APIC
  • Disable EFI

  • Use SATA storage for the drives (you'll need to install drivers for this)

Disable VT-x/AMD-V
Enable Nested Paging
These appear dependent on support for them.
