Can someone elaborate on this? I am having the same issue, but I don't understand the solution here.
What do you mean rename the column? Just name the variable name?
I have a number of these errors! Does that mean I have to rename every single column? What do I rename them to?
Run below code. That will hopefully explain it to you.
data have1; attrib A length=8 b length=8; A=1; B=1; run; data have2; attrib A length= 8 B length= $20; A=2; B='2'; run; /* throws an error because column B is of different type in source tables */ /* error indicates which column based on variable number causes the issue */ /* running proc contents over source tables will return the variable names with attributs */ /* so the problematic column is easily identified */ proc sql; create table demo1 as select * from have1 outer union corresponding select * from have2 ; quit; /* will work */ proc sql; create table demo1 as select a, b as b1 from have1 outer union corresponding select a, b as b2 from have2 ; quit;
Thanks Patrick for taking the time to post the example. It really does help!
I have a question though.
I notice that the correct proc sql code renames variables b to b1 from dataset have 1, and then renames b to b2 from dataset 2. But for the merging of the two datasets I want b1 and b2 to be in the same column.
So for example:
data set have 1 has variables a and b
data set have 2 has variables a and b
final merged data set has variables a and b which contains the data points from variables a and b from dataset have 1 and have2.
is there a way to do this?
