SQL Tutorial
SQL Select
The SQL SELECT Statement
To choose data from a database, use the SELECT statement.
Example
Return data from the Customers table:
SELECT CustomerName, City FROM Customers;
Syntax
SELECT column1, column2, …
FROM table_name;
The table you wish to pick data from has field names like column1, column2,… in this case.
The name of the table from which you wish to select data is represented by the table_name.
