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 City, CompanyName FROM [CData].[Sample].Customers WHERE Country = ?");

odbc_execute($stmt, array("US 1"));
while ($row = odbc_fetch_array($stmt)) {
    echo "City = ", $row["City"], "\n";
    echo "CompanyName = ", $row["CompanyName"], "\n";
}

odbc_execute($stmt, array("US 2"));
while ($row = odbc_fetch_array($stmt)) {
    echo "City = ", $row["City"], "\n";
    echo "CompanyName = ", $row["CompanyName"], "\n";
}
