我有一个包含很多连接的查询，使我的总列数超过 1000。为了解决这个限制，我需要使用 select * 而不是手动定义别名。

我想要做

SELECT    *
FROM      table0 t0
INNER JOIN table1 t1
ON         t0.field = t1.field
WHERE      rownum < 10

在我的结果中，我需要在列名中定义以下内容

t0.column
t0.column2
t1.column
t1.column2

是否有我缺少的概念或技术来实现这一点？我真的不想依赖现场顺序，因为它可能会改变。

也许你可以提出一个提示：

SELECT t1.*, 't1 <-> t2' , t2.*,  't2 <-> t3', t3.*

现在你最终会看到这样的东西：

 t1...................................|           | t2................|           | t3.....................|
 01-02-2012 | ... | More data from t1 | t1 <-> t2 | Some data from t2 | t2 <-> t3 | Now data from t3 | ... |
 01-02-2012 | ... | More data from t1 | t1 <-> t2 | Some data from t2 | t2 <-> t3 | Now data from t3 | ... |
 01-02-2012 | ... | More data from t1 | t1 <-> t2 | Some data from t2 | t2 <-> t3 | Now data from t3 | ... |
 01-02-2012 | ... | More data from t1 | t1 <-> t2 | Some data from t2 | t2 <-> t3 | Now data from t3 | ... |
 01-02-2012 | ... | More data from t1 | t1 <-> t2 | Some data from t2 | t2 <-> t3 | Now data from t3 | ... |
 01-02-2012 | ... | More data from t1 | t1 <-> t2 | Some data from t2 | t2 <-> t3 | Now data from t3 | ... |

而且您知道这些标记之间的所有内容都't1 <-> t2'属于表格。

您可以执行以下操作：

SELECT t0.column, t0.column2, t1.column, t1.column2, t0.*, t1.* 
FROM      table0 t0
INNER JOIN table1 t1
ON         t0.lm_mst_uid = t1.lm_mst_uid
WHERE      rownum < 10
