我正在创建一个脚本,通过某些ID Matrix ID来总结利润和损失(PL)。我对视图“vw_package”使用以下SQL语句:
select trade_matrix_id, sum(pl) from vw_package
where date (gen_timestamp) between '2012-05-01' and '2012-05-30'
and trade_matrix_id between 30 and 60
group by trade_matrix_id;
它正确地产生了这个结果:
trade_matrix_id,sum(pl)
41, -147.33
42, -27.45
43, -329.03
44, -329.03
45, -329.03
...
现在我想填写一张完全符合这些结果的表格。我在我的脚本中创建了一个表:
CREATE TABLE IF NOT EXISTS PLByMatrixID
(trade_matrix_id int,
Sum_PL float(19,2));
我使用INSERT命令用与上面完全相同的SELECT语句填充表:
insert into PLByMatrixID (trade_matrix_id, Sum_PL)
select trade_matrix_id, sum(pl) from vw_package
where date (gen_timestamp) between '2012-05-01' and '2012-05-30'
and trade_matrix_id between 30 and 60
group by trade_matrix_id;
我调用脚本并查询结果tablePLByMatrixID,PL中的所有值都为NULL:
41, NULL
42, NULL
43, NULL
...
如果有人能告诉我这里缺少什么,我感激不尽。
答案 0 :(得分:0)
尝试
select trade_matrix_id, sum(pl)
into PLByMatrixID
from vw_package
where date (gen_timestamp) between '2012-05-01' and '2012-05-30'
and trade_matrix_id between 30 and 60
group by trade_matrix_id;
