SQL Reference

Quick Reference

The TOP keyword is used to specify the number of records to return (SQL Server).

The following selects the first three records from the Customers table.

SQL Server:

SELECT TOP 3 * FROM Customers;

MySQL uses the LIMIT keyword to do the same thing.

SELECT * FROM Customers
LIMIT 3;

SQL Notes:

  • Any work being done to modify the structure of a database or delete tables or the the database itself should only be done after making a recent backup

We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
