I have two datasets bsas1 and bsas2. I want to merge these datasets by name, therefore i used the command 'by name' but it didn't worked although when i run command 'by id' it worked. Why is it so ?.
Below is the attached jpg screenshot.
A datastep merge with a by statement expects that the datasets are sorted in the order specified by the by statement. Use proc sort to achieve that.
Because your data is not sorted by name, but by ID. Run the code
proc sort data = bsas1;
by name;
run;
proc sort data = bsas2;
by name;
run;
and try again.
