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 Username, Email FROM [CData].[Administrators].Users WHERE Id = '39ef9b6f-5973-4701-bd19-7950d4b7d6e0'");

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 "Username = ", $row["Username"], "\n";
    echo "Email = ", $row["Email"], "\n";
}
