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, Name FROM [CData].[Elasticsearch].Employee WHERE Industry = ?");

odbc_execute($stmt, array("Floppy Disks 1"));
while ($row = odbc_fetch_array($stmt)) {
    echo "Id = ", $row["Id"], "\n";
    echo "Name = ", $row["Name"], "\n";
}

odbc_execute($stmt, array("Floppy Disks 2"));
while ($row = odbc_fetch_array($stmt)) {
    echo "Id = ", $row["Id"], "\n";
    echo "Name = ", $row["Name"], "\n";
}
