我已多次搜索,但找不到符合我要求的正确查询。在示例图像中,我希望将所有匹配的数据放在一行中,并在Apex交互式报表应用程序中使用pl / sql将建议(s)列下的数字与逗号结合使用。
看起来像这样:
0177 || Martinez,Melchor || 24-OCT-13 || 1 || 17 || 1,2,8 ||
0178 || Saxon,Victoria || 16-OCT-13 || 2 || 748 || 4,5 ||
答案 0 :(得分:1)
alter session set nls_date_format = 'dd-MON-rr'; -- NOT PART OF THE QUERY
with test_data ( subject_number, patient, mdt_date, pres_phys, cr_mdt_phys, recomm ) as (
select '0177', 'Martinez, Melchior', to_date ('24-OCT-13'), 1, 17, 1 from dual union all
select '0177', 'Martinez, Melchior', to_date ('24-OCT-13'), 1, 17, 2 from dual union all
select '0177', 'Martinez, Melchior', to_date ('24-OCT-13'), 1, 17, 8 from dual union all
select '0178', 'Saxon, Victoria' , to_date ('16-OCT-13'), 2, 748, 4 from dual union all
select '0178', 'Saxon, Victoria' , to_date ('16-OCT-13'), 2, 748, 5 from dual
)
-- End of simulated inputs (for testing purposes only, not part of the solution).
-- SQL query begins BELOW THIS LINE.
