SQL

I've hit a wall in my SQL studies via the Khan Academy, and as such, I am engaging in additional studies prior to attempting to move forward.

Via a very limited, free SQL tutorial from Codecademy:

BACKGROUND

SQL, Structured Query Language, is a programming language designed to manage data stored in relational databases. SQL operates through simple, declarative statements. This keeps data accurate and secure, and it helps maintain the integrity of databases, regardless of size.

Here’s an appendix of commonly used commands.

COMMANDS

ALTER TABLE

ALTER TABLE table_name 
ADD column_name datatype;

ALTER TABLE lets you add columns to a table in a database.

SQl + SoloLearn = Amazing

I've spent the last several hours studying Structured Query Language (SQL) and I am really enjoying the straightforward syntax and ease of use that it offers. Having studied PHP previously is also helping.
