Subject:      A simple question on data update

Hi there

I wanna update the x values in data1 with the one in data2. While the merge statement only changes the x value of the first record for id 2 and the second one stays unchanged. Any ideas to fix this. TIA.

data data1; input id x; datalines; 1 5 2 8 2 8 3 7 ; data data2; input id x; datalines; 1 99 2 77 ;run;

data test; merge test new; by id; run;
