PostgreSQL on the command line

I am just getting back into PostgreSQL.  Here are the things I had to learn today:

1.  Command line usage:
  • su - postgres
  • psql
  • select version();
2.  Dumping data for import on another server
  • pg_dump -o mydb -U postgres -W > mydb.sql
  • -o has to do with oids (Not sure if I need this yet)
  • -U is for user
  • -W is for password.  It prompts when you run the command

Boy I wish there was a way to create a table from a select query

I was doing some SQL work today when I had a thought: Boy I wish there was a way to create a table from a select query I started in Navicat to see if it was possible.  After find nothing I decided to google it all the while thinking in my head how I was going to create a script to do this if I couldn't find anything. I found something. I was happy yet sad.  Happy because I didn't have to take the time to create something.  Sad because I didn't have to create the tool.  It sounded like a fun project. What did I find you ask? The "Create Table as" statement. CREATE TABLE [ IF NOT EXISTS ] new_table [ AS ] SELECT expressions FROM existing_tables [WHERE conditions]; The best part about it is the statement knows to go to the existing tables to get the column type, size etc.   Such a tremendous time saver.  I cannot believe in all my years of programming I never stumbled upon this type of statement.

So after doing a little research on my end I ended up calling the UPS technical support phone number for the United States: Over the phone we went over the following steps: UPS.COM You must add and authenticate your account using Account Summary to view Negotiated Rates in UPS Internet Shipping, Time and Cost Calculator on ups.com, and the UPS Developer Kit - Shipping and Rating APIs.

Git GUI for Windows

This past weekend I needed to upload code to github.  I chose to use the GitHub for Windows which made it painless. Today I decided to research and see what other GUI clients I could find for GIT. I stumbled upon SourceTree  by Atlassian Software. It was really easy to setup a local repository as well as connecting to GitHub. My favorite feature so far besides the ease of use is the dashboard that shows you the files that need committed and the diff details right beside it. Here is a screenshot:
