MySQL中存储过程的问题

Question

我做了以下程序：

/*Stored procedure*/
 create procedure SP_getlagerstatus(in Kategori VARCHAR(15), in minverdi int(3))
 select * from deler join delekategori on deler.DelekategoriID=delekategori.DeleKategoriID
 where DeleKategoriNavn ='Kategori' and Lagerstatus > 'minverdi';

当我用call SP_getlagerstatus('biler',1);运行它时，我没有得到任何结果，但当我直接运行查询时：

select * from deler join delekategori on deler.DelekategoriID=delekategori.DeleKategoriID
 where DeleKategoriNavn ='biler' and Lagerstatus > 1;

我得到了理想的结果。我错过了什么？
