Laravel – Eloquent ORM

Following are a few examples of Laravel Eloquent ORM. Each expression is accompanied by its SQL analog.


I’ve been playing around with CodeIgniter in my spare time and decided to release one of my projects into the wild. QuizMotor is a simple app to flow through multiple choice question as if you were taking a quiz. As of now the questions are about CodeIgniter, PHP, HTML, etc, but I’m hoping that it will grow to cover a variety of subjects. Check it out: 

DB2 Cheat Sheet (Instances)

Managing DB2 instances is a substantial portion of a DB2 DBA’s daily workload. Here’s a simple cheat sheet I’ve designed to define a DB2 instance and outline the basics of an instance’s memory model, process model, and file structure. I’ve also listed a few commands that are specific to instance management (creating, dropping, starting, stopping, etc).



DB2 Cheat Sheet (Commands)

While preparing for a DB2 interview, I compiled a list of DB2 commands and grouped them by purpose. FYI, notice how DB2 system commands are essentially binaries (db2start, db2licm, db2ilist) and as a result are path dependent. On the other hand, Command Line Processor (CLP) commands are executed directly from a DB2 prompt or from the command line using db2 “execute some command”.


Querying DB2 with Python

In this article, we’ll write a simple Python script that will query a DB2 database and print the results. To link Python and DB2, we’ll use the PyDB2 interface. To install PyDB2 download a copy and follow the instructions in the README file.

#!/usr/bin/env python

import DB2

# Instantiate connection object and connect to DB2 database
db = DB2.connect('dbname', 'username', 'password')

# Instantiate cursor object
cursor = db.cursor()

# Build sql statement using python's multiline quotation syntax
sql = """select address_line_1 , address_line_2,
        city, state, zip from property"""


    # Execute statement and fetch results
    results = cursor.fetchall()

    # Loop through rows and print all columns
    for row in results:
        print row[0:]

    print "Error: Unable to fetch data from DB2"

# Close database connection
