存储过程传日期参数无法查询数据？
本帖最后由 leech125 于 2012-12-07 16:49:14 编辑 我执行以下代码row_count=0
declare
row_count number;
END_DATE DATE; --进出数量累计计算结束时间
begin
END_DATE := SYSDATE;
row_count := 0;
select count(*)
into row_count where passdate < end_date
from table ；
end;
我执行以下代码row_count > 0
declare
row_count number;
begin
row_count := 0;
select count(*)
into row_count where passdate < SYSDATE
from table ；
end;
两者区别是什么？
[解决办法]
先 SET SERVEROUTPUT ON
然后
declare
row_count number;
END_DATE DATE;
begin
END_DATE := SYSDATE;
row_count := 0;
select count(*)
into row_count
from sapdt_wakh where logdate < end_date;
dbms_output.put_line('this is the count:'
[解决办法]
to_char(row_count));
end;
[解决办法]
END_DATE := SYSDATE;
这样子赋值的话，END_DATE的值就是 NLS_DATE_FORMAT里面设置的格式
