帮忙看看这段程序有没有错误

Question

QryDept.Active:=true;
QryDept.locate('deptname',combobox3.Text ,[]);
deptcode:=QryDept.fieldbyname('deptcode').asstring;
QryDept.Locate('deptname',combobox4.Text ,[]);
newdeptcode:=QryDept.fieldbyname('deptcode').asstring;
QryDept.Active:=false;
QryDept的Sql的内容 ：select * from c_deptname

Answer 1

QryDept.Locate('deptname,deptcode',vararryof(combobox3.Text,combobox4.Text ) ,[]);

Answer 2

没有大问题：
QryDept.Active:=true;
//加上if更严格
if QryDept.locate('deptname',combobox3.Text ,[]) 
then deptcode:=QryDept.fieldbyname('deptcode').asstring;
if QryDept.Locate('deptname',combobox4.Text ,[]) 
then newdeptcode:=QryDept.fieldbyname('deptcode').asstring;
QryDept.Active:=false;
