我目前正在使用以下查询来提取相同样本记录中以4行表示的数据,并希望将其展平为每个样本1个ow。非常感谢您附加查询结果以获取任何帮助。
select s.name as CRF, a.name as Aliquot_Name, a.aliquot_type, au.u_step_yield as Step_Yield, au.u_step_concentration as Step_Concentration, au. u_pooled_plasma_volume as Pooled_Plasma_volume
from aliquot a
join aliquot_user au on a.aliquot_id = au.aliquot_id
join sample s on s.sample_id = a.SAMPLE_ID
where a.aliquot_type in ('DNA Extracted', 'Library', 'Target Enrichment', 'DNA Plasma')
order by s.name desc, a.aliquot_type, a.name, au.u_step_yield, au.u_step_concentration, au.u_pooled_plasma_volume;

我认为你必须更具体。 没有桌子的信息。这是pk而不是。 我现在只能说,如果你想要平整行,你必须加入同一个表。 如果您想通过查询获得答案,则必须编写表格信息,其他人可以帮助人们回答您的问题。

据我了解您的数据,您可以在表格中输入4个不同的a.aliquot_type(' DNA Extracted',' Library',' Target Enrichment&# 39;,' DNA Plasma')。并且你想给4列带有相应的Aliquot_Name(一个用于' DNA Extracted'等)。
您可以使用带有子选择的4列,您可以从等分中读取相应的数据,因此您必须退出连接
a.aliquot_id = au.aliquot_id
例如:
select s.name as CRF, (select a.aliquot_type from aliquot where a.aliquot_type = 'DNA Extracted' and ....) col1, (select a.aliquot_type from aliquot where a.aliquot_type = 'Library' and ....) col2, ...
