使用来自另一个表列数据的列名创建临时表
是否可以创建一个临时表,其中的列以来自另一个表中单个列的数据命名 -
Is it possible to create a temp table with columns named with data from a single column in another table for example -
singleColumn
-data1
-data2
-data3
-data4
然后从这里创建一个临时表,如 -
then from this create a temp table like -
data1 | data2 | data3 | data4
我有一个用户,可以将人口统计表中的任何人口统计数据设为 0.联接将为用户返回多行.我需要将这些数据连接到 1 行,以便将这些数据存储在 CSV 文件中.
I have a user that can have 0 to whatever demographics from the demographics table. A join will return several rows for a user. I need this data joined on 1 row so I can store this data in CSV file.
推荐答案
不要认为以我想要的方式返回数据是可能的,所以最终用 2 个 DataTables 来做.
Don't think its possible to return data the way I would like so ended up doing doing it with 2 DataTables.
