Merging two datasets with different number of rows

[Saskin Kakoli]

I have two datasets like:

Dataset1:

HH   ID   Weight(kg)
 1    1     36
 1    2     25
 1    3     40
 2    4     56
 2    5     76
 2    6     45
 3    7     43
 3    8     63

Dataset2:

HH     ID    Height(m)
 1      2      1.2
 2      5      1.6
 3      8      1.5

Now I want to merge these two datasets for the common HH and ID. That is, after merging the datasets will be looked like:

HH    ID    Height(m)   Weight(kg)
1      2     1.2              25
2      5     1.6              76
3      8     1.5              63

How can I code to do this?
Please help me out!

use dataset1, clear
merge 1:1 HH ID using dataset2, keep(match) nogenerate
