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 ID, Leave_Type FROM [CData].[Employee Management].Leave_Types WHERE Leave_Type = ?");

odbc_execute($stmt, array("Sick 1"));
while ($row = odbc_fetch_array($stmt)) {
    echo "ID = ", $row["ID"], "\n";
    echo "Leave_Type = ", $row["Leave_Type"], "\n";
}

odbc_execute($stmt, array("Sick 2"));
while ($row = odbc_fetch_array($stmt)) {
    echo "ID = ", $row["ID"], "\n";
    echo "Leave_Type = ", $row["Leave_Type"], "\n";
}
