如何从表中选择所有列,以及 ROWNUM 等附加列?
在 Oracle 中,可以执行 SELECT
语句,将行号作为结果集中的列返回.
例如
SELECT rownum, column1, column2 FROM table
返回:
<前>rownum column1 column21 乔·史密斯2 鲍勃·琼斯但我不想手动指定每一列.我想做类似的事情:
select rownum,* from table
<前>rownum column1 column2 column3 column41 乔·史密斯 1 22 鲍勃·琼斯 3 4
有什么想法吗?
解决方案用表名来限定*:
select rownum, table.* from table
In Oracle, it's possible to do a SELECT
statement that returns the row number as a column in your result set.
For example,
SELECT rownum, column1, column2 FROM table
returns:
rownum column1 column2 1 Joe Smith 2 Bob Jones
But I don't want to specify each column by hand. I want to do something like:
select rownum,* from table
rownum column1 column2 column3 column4 1 Joe Smith 1 2 2 Bob Jones 3 4
Any ideas?
解决方案Qualify the * with the name of the table:
select rownum, table.* from table
