result set pointer method in DB?

Hi, wouldnt it be useful to have a method for manipulating the result set pointer in PEAR:DB? Please correct me if i am wrong, but right now you can do something like $res->fetchRow($fetchmode, 0)) but this wont solve it exactly. Assume something like this: SQL = "some sql" RES = DO QUERY while($row = RES->fetch) DO SOMETHING IN A LOOP MOVE RES POINTER to 0 while($row = RES->fetch) DO SOMETHING DIFFERENT IN A LOOP I cant see how to achieve this with the current PEAR:DB in an elegant way... I dont know all supported databases of course, but this should be a feature each database is capable of or? -- Marc Logemann (aka Loge, www.marc-logemann.de)
