Question

Is it possible to use select * for only one table when using a join statement?

Let’s say these are the following tables;

B
userID
username

A
userID
entry 
....just pretend there are more columns for the sake of this example

What is the correct way to look up the username from table B?

select B.username, * from A
LEFT JOIN B on B.userID = A.userID
where A.entry = "XXXXX"

Or do I have to list out everything I want to select such as:

select B.username, A.userID, A.entry from A
left Join.....

Answer 1

You can use [table name].* to select all fields from one of the tables. For example, to select all fields from table B use:

 SELECT B.*, username FROM A
 LEFT JOIN B on B.userID = A.userID
 WHERE A.entry = "XXXXX"

edit – selected column username from A
