从未找到的关键字 - Oracle CRXI命令

Question

我正在尝试在Oracle数据库的CR XI中创建一个union作为命令。但是，当我尝试保存命令时，表明'找不到FROM关键字'。

代码好吗？有任何想法吗？

SELECT *, "H3"  as "Type" FROM TABLEH3
WHERE CURRENT_FLAG = '1'
UNION ALL
SELECT *, "H4" as "Type" FROM TABLEH4
WHERE CURRENT_FLAG = '1'
UNION ALL
SELECT *,  "H5" AS "Type" FROM TABLEH5
WHERE CURRENT_FLAG = '1'
UNION ALL 
SELECT *, "'H6" AS "Type" FROM TABLEH6
WHERE CURRENT_FLAG = '1';

干杯

我没有你的表结构，但这可能适合你，你需要别名*引用的表

SELECT t1.*, 'H3'  as "Type" FROM TABLEH3 t1
WHERE CURRENT_FLAG = '1'
UNION ALL
SELECT t4.*, 'H4' as "Type" FROM TABLEH4 t4
WHERE CURRENT_FLAG = '1'
UNION ALL
SELECT t5.*, 'H5' AS "Type" FROM TABLEH5 t5
WHERE CURRENT_FLAG = '1'
UNION ALL 
SELECT t6.*, 'H6' AS "Type" FROM TABLEH6 t6
WHERE CURRENT_FLAG = '1';
