Parameterized Statements
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 RespondentId, ChoiceId FROM MySurvey_Responses WHERE ChoiceText = ?"); odbc_execute($stmt, array("blue 1")); while ($row = odbc_fetch_array($stmt)) { echo "RespondentId = ", $row["RespondentId"], "\n"; echo "ChoiceId = ", $row["ChoiceId"], "\n"; } odbc_execute($stmt, array("blue 2")); while ($row = odbc_fetch_array($stmt)) { echo "RespondentId = ", $row["RespondentId"], "\n"; echo "ChoiceId = ", $row["ChoiceId"], "\n"; }
