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 MANDT, MATNR FROM MARA WHERE ERNAM = 'BEHRMANN'");

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 "MANDT = ", $row["MANDT"], "\n";
    echo "MATNR = ", $row["MATNR"], "\n";
}
