Query Methods
Relational database management (RDBMS)
Structured Query Language (SQL)
We use the command term query to explore SQL databases. all SQL code is written in the form of a query statement and this executed against the database
Every query statement begins with a clause such as DELETE, CREATE, SELECT or update
An example of simple SQL statement is: CREATE DATABASE Sports Club
SET = To Change
The select command can be used to extract data from a database that has been created onnce the relevant data has been added to the tables.
