I have a table “A” with details like subscriber_no, name, age, occupation Eg of one of the records : Adam, 35, Data Analyst And table “B” with similar info subscriber_no, name, age, occupation and AN EXTRA COLUMN named CITY Eg: Adam, 30, Director, Toronto Ella, 40, Manager, Vancouver I want the info in the final merged table as : if the subscriber_no exists in table A, take all the information for that subscriber from table A and just add the CITY : Toronto to it say, Name : Adam, 35, Data Analyst, Toronto I do not want the info from B at all EXCEPT adding CITY if the subscriber no exists in A. However, if the subscriber no does not exist in A then I want all information about it from B So the final tbale should look like: Adam, 35, Data Analyst, Toronto Ella, 40, Manager, Vancouver How can I achieve this? Thanks in advance:)
