合并两个数据集


数据类型不一样，要给他们合并，用sql
自己编的程序是这样
有error 显示
ERROR: Column 2 from the first contributor of UNION ALL is not the same type as its counterpart from
       the second.
ERROR: Column 3 from the first contributor of UNION ALL is not the same type as its counterpart from
       the second.
ERROR: Column 4 from the first contributor of UNION ALL is not the same type as its counterpart from
       the second.

但是corr 不是可以合并不是同一个类型的么

这里的corr也不是蓝色的

改成outer union corr 还是不行

请教各位大牛！！！
