You annoy technical people on your team

Hack together rough approximations for hours



“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
