Database Infrastructure

IMPORTANT NOTE A Database Server can not have a DB with the same name. Since we use ONE DB Server, all our DBs have to have unique names.

Database Structure (mySQL) mySQL is a database. mySQL is a database. Databases contain objects called tables. Databases contain objects called tables. A table is a collections of related data organized in columns and rows. A table is a collections of related data organized in columns and rows. Access to information is through SQL (Structured Query Language). Access to information is through SQL (Structured Query Language).

Steps to interact with DB 1. Connect to server 2. Connect to DB 3. Create SQL statement 4. Execute SQL > Create record object 5. Convert record object into array 6. Close connection

Information needed for DB Need server name/IP (e.g. mysql..com or localhost) Need server name/IP (e.g. mysql..com or localhost) Need username Need username Need password Need password Need DB name Need DB name Need table names Need table names Need column names Need column names

IMPORTANT NOTE SQL Commands (SELECT, INSERT, UPDATE, etc) are almost always written in CAPS and other pieces of a SQL statement are written as normal case.

PHP / mySQL Syntax // Connect to server $con = mysql_connect(“SERVER",“USER",“PASSWORD"); // Connect to DB mysql_select_db(“DATABASE", $con); // Execute SQL Query $result = mysql_query("SELECT * FROM TABLE"); // Close connection mysql_close($con);

PHP / mySQL Syntax // When query has information returned // need to hold the information for display $result = mysql_query("SELECT * FROM Persons"); // The RECORDSET will be an object (e.g. $result) // Need to break the object into an array (e.g. $row) while($row = mysql_fetch_assoc($result)) { // The WHILE runs until END OF RECORD echo $row['FirstName']. " ". $row['LastName‘]." "; }

Sample SQL Statements SELECT * FROM Persons; SELECT ‘FirstName’ FROM Persons WHERE AGE>30; INSERT INTO Persons (FirstName, LastName, Age) VALUES ('Peter', 'Griffin', '35'); UPDATE PERSONS ‘FirstName’=‘Peg’ WHERE id=5; Never do a DELETE statement, instead “archive” the date.

IMPORTANT NOTE The life cycle in PHP is the length of time it takes the server to find the file, process the information, and send the completed static HTML back to the client.
