If airports table is huge, is it better to join it just once on multiple condition. something like flights f inner join airports a on a.code = f.fairport or a.code = f.tairport please suggest.

The question and solutions pertain specifically to inner joins. if the join is a left/right/full outer join, then it is not a matter of preference or performance, but one of correct results. the sql cookbook (§ 11.3. incorporating or logic when using outer joins) demonstrates the difference between the join and where conditions. The first query employs some lesser known ansi sql syntax which allows you to nest joins between the join and on clauses. this allows you to scope/tier your joins and probably opens up a host of other evil, arcane things. Inner join gets all records that are common between both tables based on the supplied on clause. left join gets all records from the left linked and the related record from the right table ,but if you have selected some columns from the right table, if there is no related records, these columns will contain null.

In most inner join queries (one to many relationships), i could rewrite them to use cross apply, but they always give me equivalent execution plans. can anyone give me a good example of when cross apply makes a difference in those cases where inner join will work as well? edit: here's a trivial example, where the execution plans are exactly the. I'm pretty new to python and am completely confused by .join() which i have read is the preferred method for concatenating strings. i tried: strid = repr(595) print array.array('c', random.sample(. Theta join is analogous to a special case of inner join where the on is a theta comparison on of a column from each. some decades after codd defined them some textbook (s) misdefined theta join as a generalization that is the analogue of inner join. This was an example, but the point is as eric said in how can i do an update statement with join in sql server?. you need to add an update statement at first with the full address of all tables to join with, and then add the set statement.
