Question

I want to select all the fields from one table and also some specific fields from other tables using LEFT JOIN. Can I use the * to select all the columns from the one table and also name the specific fields from the JOIN?

Something like this:

SELECT * , table2.a, table2.b 
FROM table1
LEFT JOIN table2 ON table2.a = table1.a
WHERE ...

Answer 1

To get all the fields from table1 and only certain columns from table2 you would use:

SELECT table1.*, table2.column, table2.column
FROM table1
LEFT JOIN table2 ON table2.a = table1.a
WHERE ...
