The following code example shows how to bind parameters to create parameterized statements.

Reusable Statements

The odbc_prepare function creates prepared statements, which can be re-used across multiple calls to odbc_execute. The statement object can be used to fetch results like a non-parameterized query.

$stmt = odbc_prepare($cnx, "SELECT ShipName, ShipCity FROM \"postgres\".\"schema01\".Orders WHERE ShipCountry = ?");

odbc_execute($stmt, array("USA 1"));
while ($row = odbc_fetch_array($stmt)) {
    echo "ShipName = ", $row["ShipName"], "\n";
    echo "ShipCity = ", $row["ShipCity"], "\n";
}

odbc_execute($stmt, array("USA 2"));
while ($row = odbc_fetch_array($stmt)) {
    echo "ShipName = ", $row["ShipName"], "\n";
    echo "ShipCity = ", $row["ShipCity"], "\n";
}
