我在toad中运行查询以测试结果，但我收到错误

ORA-00933：SQL命令未正确结束

这是我的查询

                FROM DUAL

请告知这里有什么问题

Answer 1

你的两个较大的SELECTS（前2个）将返回12个项目。最后两个SELECTS（小的）返回13个项目。 UNION必须有匹配的列。

例如声明应该结束......

SELECT NULL, 0, 'ABC', NULL, NULL, NULL,
'ABC', NULL, NULL, NULL, NULL, NULL
FROM DUAL

UNION

SELECT NULL, 0, 'XYZ', NULL, NULL, NULL,
'XYZ', NULL, NULL, NULL, NULL, NULL
FROM DUAL

Oracle Query提供错误
