Subject: Patients who are in either of three tables
Content-Type: text/plain; charset=iso-8859-1
I am trying to get patients who are either in table1 or Table 2 or Table3. Should be not complicated ...but I am kind of confused at the end of Friday as it is a kind of an urgent matter...
I have patients' id s, flag and program fields.
How Can I implement it with code? I do not have any duplicats in either table.
Could you please help me with that? Thank you in advance,
