Need some help with merge

Hey,

I try to merge DATA1 (Main table) with an extern table (DATA2) by an ID to delete some irrelevant observations.

Normally in DATA3 there are all observations togehter. But i need only the observations of the extern table (DATA2). In this case I need n=439.

NOTE: There were 512 observations read from the data set DATA1.

NOTE: There were 439 observations read from the data set DATA2.

NOTE: The data set WORK.DATA3 has 515 observations and 12 variables.

i hope that someone can help me please.

It would have helped to see the code which created the log.

Something like below might give you what you're looking for:


data data3;
  merge data1 (in=d1) data2 (in=d2);
  by id;
  if d2;
  /* more statements */
run;
