Question

我试图在 SQL 查询中使用变量但失败了。这样做的方法是什么？

 var SicilNumvber = SessionCurrentUser.EMPNO;
                    string query = "select * from crm_visible_v where ownerid in (select sicilno from personel.pkim_kutlama@netdb_1.europe.nortel.com where cikis_tarihi is null start with sicilno = :SicilNumvber   connect by prior sicilno = amir)";

     string query := 'select * from crm_visible_v where ownerid in (select sicilno 
     from personel.pkim_kutlama@netdb_1.europe.nortel.com where cikis_tarihi is null    
     start with sicilno ='||SicilNumvber||' connect by prior sicilno = ''''amir'';
