Prepared statements get wrong colum values

Assuming, a table has the columns "id" and "idclient", preparing a statement like
SELECT * FROM :table WHERE id = ':id' AND idclient = ':idclient'
will not work, because ":id" in ":idclient" will be replaced by the value of "id".
Therefore, assuming "id" has the value "2", and "idclient" has the value "1", the statement gets
SELECT * FROM :table WHERE id = '2' AND idclient = '2client'
instead of
SELECT * FROM :table WHERE id = '2' AND idclient = '1'
