当我执行以下查询时,其获取错误如"ORA-00904: "R"."MEASURE": invalid identifier"
我认为查询没错。但是我找不到这个问题。你能帮我吗...
谢谢。
SELECT DISTINCT 0 ROW_ID, Division , Outlet , Class , Package , Type , Measure
FROM NEW_OUTLET_TOTAL_PLAN_2013 S
WHERE NOT EXISTS
(SELECT 1
FROM TEMP_BWXROW3 R
WHERE
R.Division = S.Division AND
R.Outlet = S.Outlet AND
R.Class = S.Class AND
R.Package = S.Package AND
r.type = s.type and
R.Measure = S.Measure );

执行此操作:
SELECT *
FROM USER_TAB_COLS
WHERE UPPER(TABLE_NAME) = 'TEMP_BWXROW3' AND
UPPER(COLUMN_NAME) = 'MEASURE'
这将显示使用的确切列名称。密切关注列名称的大小写(上限,下限或混合)。如果不是全部大写(即' MEASURE'),则在使用时需要将列名括在双引号中。因此,例如,如果实际的列名称为' Measure'您需要将查询更改为
SELECT DISTINCT 0 ROW_ID, Division , Outlet , Class , Package , Type , Measure
FROM NEW_OUTLET_TOTAL_PLAN_2013 S
WHERE NOT EXISTS
(SELECT 1
FROM TEMP_BWXROW3 R
WHERE
R.Division = S.Division AND
R.Outlet = S.Outlet AND
R.Class = S.Class AND
R.Package = S.Package AND
r.type = s.type and
R."Measure" = S.Measure);
分享并享受。

TEMP_BWXROW3中是否包含区分大小写的列名?如果是,那么使用R。" Measure" ...
