join

sql to return unique list of UserID's based on 2 tables.

(not discussing the table design, its a done deal!) I know how to do this query using a WHERE NOT IN clause, but I was wondering how it could be done using a join. Note: rows are not unique, so we have to do a DISTINCT so as to not get duplicates. Users (userID) OldUsers(UserID) So using the WHERE NOT IN clause I can do: SELECT DIS...

Mysql Using JOINs and WHERE statment. What is this difference?

What is the difference bettween SELECT a.AccountId FROM Accounts AS a JOIN domain as d; and SELECT a.AccountId FROM Accounts AS a JOIN domain as d WHERE a.AccountId=d.AccountId; I thought JOIN is an inner join which only matches when the left AccountId is == to the right AccountId.

Is there a convenient way to alias only conflicting columns when joining tables in SQLAlchemy?

Sometimes it is useful to map a class against a join instead of a single table when using SQLAlchemy's declarative extension. When column names collide, usually in a one-to-many because all primary keys are named id by default, you can use .alias() to prefix every column with its table name. That is inconvenient if you've already written...
