After Connecting, you can execute a SQL statement and retrieve the results.

SELECT Procedure

You can execute queries using odbc_exec. This will return a resource that you can use to read results.

$stmt = odbc_exec($cnx, "SELECT CustNum, Company FROM Customers WHERE CompanyName = 'CompanyName'");

Iterating over the Results

You can use odbc_fetch_array to fetch the next row as an array.

while ($row = odbc_fetch_array($stmt)) {
    echo "CustNum = ", $row["CustNum"], "\n";
    echo "Company = ", $row["Company"], "\n";
}
