Cake PHP =>组合条件数组和SQL语句

how can I combine a conditions array and a normal SQL statement? My conditions array looks like the following one:

[conditions] => Array
    (
        [AND] => Array
            (
                [0] => Array
                    (
                        [Webdetail.kW1 LIKE] => %%
                    )

                [1] => Array
                    (
                        [Webdetail.Upm1 LIKE] => %%
                    )

                [2] => Array
                    (
                        [Webdetail.Volt1 LIKE] => %%
                    )

But in some cases I have to use a normal SQL statement for the Webdetail.Upm1 field, instead the LIKE. The SQL statement looks like: between 500*.9 and 500*1.1 and pol1=12

Thank you, Nico

Add this into your conditions:

'Webdetail.Upm1 BETWEEN ? AND ?' => array(500 * 0.9, 500 * 1.1)
