Possible Duplicate: Is there an Oracle SQL query that aggregates multiple rows into one row?

我正在尝试创建一个SQL查询，该查询可以从表中返回数据以在一行中显示一列的多个值.

I'm trying to to create a SQL query that can return data from a table to display multiple values of a column in one row.

例如，这是表格设置:

SEQ ROWSEQNUM ASSISTING_ASSOCIATES 100 2 19332816 100 1 1366344 103 1 12228238 104 1 1366474

我需要查询结果如下:

SEQ ROWSEQNUM ASSISTING_ASSOCIATES 100 1 1366344; 19332816 103 1 12228238 104 1 1366474

有人有见识吗?

推荐答案

我认为这应该起作用，假设对于每个SEQ值，总会有一行带有ROWSEQNUM=1的行，并且ROWSEQNUM的值按顺序增加没有缝隙.

I think this ought to work, assuming that for each SEQ value there is always a row with ROWSEQNUM=1 and the values for ROWSEQNUM increase sequentially with no gaps.

select seq, min(rowseqnum), max(assoc_list) from ( select seq, rowseqnum, sys_connect_by_path(assisting_associate,';') assoc_list from assoc_table start with rowseqnum=1 connect by seq = prior seq and rowseqnum = prior rowseqnum + 1 ) group by seq
