Randomly match subject ID with blind id

[Div_sas]

Hi,

I have two datasets, one has 100 subject IDs and the other has 100 Blind ids, is there a way to randomly merge/match these two datasets so that each subject ID gets a blind id assigned to it

I have:

dataset 1:

blind id

1-119

1-123

1-102

1-155

dataset2: subject ID

122

234

345

566

 I want:

subject ID	blind id
122	1-123
234	1-155
345	1-119
566	1-102

Thank you.
