 You annoy technical people on your team

 “Starting in 2013, after the CMO realizes that
he/she does not have the skill sets in place for
data analytics proficiency, 50% of new marketing
hires will have technical backgrounds.”

 SQL will help you see, understand and improve
your company’s metrics.
 It allows you to access data other analytics tools
cannot

 Make data-driven decisions
 Run profitable campaigns using data
 Understand every metric in your business
 Get superpowers

A database works a lot like an Excel spreadsheet. It
will contain multiple tables all with unique names,
like “Customers” with each table containing rows
and columns

 Auto-updating information
 Easier to query
 Can visualize data automatically

Select- This command tells SQL what data you want to
see. This data needs to be a part of the table you’re
accessing.

Form – This command tells SQL where to pull the data
from. What’s the name of the table you’re using to
capture data? Put that after the “ from” statement.

Join – This command temporarily joins two tables we’d like
to search, So that we can pull data from multiple queries.
“Join” tells SQL which table we’d like to join, and the “on”
modifier tells SQL which columns in those tables should
map to each other.

Where – This statement tells SQL how to access the right
data. In this case, we’re telling it to show us users who
have gotten errors in production AND who how have
signed up within a certain time period.

Order by – This statement tells SQL how to order your
data. This can be useful when pulling massive amounts of
information from the database

Limit – This tells SQL how much data to return. In our case,
we’ll only receive the first 15 results that fit the results of
this query

 Avg() – returns the average value
 Count() – returns the number of rows
 First() – returns the first value of a column or rows
 Last() – returns the last value
 Max() – returns the largest value
 Min() -- returns the smallest value
 Sum() – returns the sum
Functions

 phpMyAdmin
 Heroku Postgres Dataclips
 Eclipse SQL Explorer
 SquirreL
