保证两个数据表结构相同,如不相同只能同步相同字段;

只是思路,具体请根据需求修改.

declare

cursor csrn_mon
is
select *
from table2;
row_mon csrn_mon%rowtype; cursor csrn_loc
is
select *
from table1;
row_loc csrn_loc%rowtype; cursor csrn_del
is
select xh from table1 minus select xh from table2;
row_del csrn_del%rowtype; cursor csrn_ins
is
select xh from table2 minus select xh from table1;
row_ins csrn_ins%rowtype; begin for row_mon in csrn_mon loop
for row_loc in csrn_loc loop
if row_loc.xh = row_mon.xh then
dbms_output.put_line('更新信息:' || row_loc.xh);
end if;
end loop;
end loop; for row_del in csrn_del loop
dbms_output.put_line('删除信息:' || row_del.xh);
end loop; for row_ins in csrn_ins loop
dbms_output.put_line('插入信息:' || row_ins.xh);
end loop; end;
