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 Type, DatasetName FROM Schemas WHERE ProjectId = ?");

odbc_execute($stmt, array("bigquery-public-data 1"));
while ($row = odbc_fetch_array($stmt)) {
    echo "Type = ", $row["Type"], "\n";
    echo "DatasetName = ", $row["DatasetName"], "\n";
}

odbc_execute($stmt, array("bigquery-public-data 2"));
while ($row = odbc_fetch_array($stmt)) {
    echo "Type = ", $row["Type"], "\n";
    echo "DatasetName = ", $row["DatasetName"], "\n";
}
