* FILENAME : CallSP.php
*
* DESCRIPTION :
* Simple ODBC (PDO ODBC) example to SELECT data from a table
* via a stored procedure
*
* Illustrates the most basic call, in the form :
*
* {CALL pSelect_Records ()}
*
* ODBC USAGE :
* Connects to Data Source using Data Source Name
* Drops and recreates a procedure 'pSelect_Records'
* Executes the procedure using stmt->execute()
* Calls stmt.fetchall() to retrieve a rowset of all rows
* For each record displays column values
* Closes statement and data base connection
