我创建了以下简单视图:
CREATE VIEW cs.MyTestPO AS
SELECT ttdpur401100.t_orno
, ttdpur401100.t_item
, ttcibd001100.t_dsca
FROM ttdpur401100
JOIN ttcibd001100 ON ttcibd001100.t_item = ttdpur401100.t_item
然后SELECT * FROM cs.MyTestPO
返回 276376 行
如果我自己运行 select 语句
SELECT ttdpur401100.t_orno
, ttdpur401100.t_item
, ttcibd001100.t_dsca
FROM ttdpur401100
JOIN ttcibd001100 ON ttcibd001100.t_item = ttdpur401100.t_item
它返回 277488 行
谁能建议为什么视图缺少 SELECT 语句返回的 1112 行。
