Hi all, is there a way to select records from two tables where the right hand side table may or may not have a matching record ? What I'm trying to do is produce a yearly report of sales per month per salesperson and if there are no entries for a given month I still want a record for the salesperson but showing a zero amount. I've looked at various *solutions* on the web but they all produce a null set which is not what I want. Null values for the sales is acceptable but I always want the salesperson name returned
// Table 1 ( Salesperson )
Hi there and thank you for your time, please accept my apologies for the misinformation I was typing from memory on the train, the actual data structures are as follows , as you can see the first table can have many records for owner_id and many records for the same month
owner_id close_date opp_id

Schema is the actual structure of the database described in such a form that understandable to humans...
A schema will contain definitions for tables, views, indexes, relations, procedures, functions and every other aspects can be accesses in the db...There is a possibility that for the same database there are several schemas, divided by access rights...So a schema is not equal the database but more a way one can see the database with the proper access rights...

I'm new to mysql .. I need a One to many ralation tutorial.. like for example I made a table called MovieList with 1 column name TitleMovie and now I want to create another table called acc1_MyWatchlist and inside of it was also a TitleMovie..my question is I want insert a value in acc1_mywatchlist but only the available values in Movielist's TitleMovie and If I tried to create another table acc2_mywaychlist it should be the same as the first table and if I tried to edit some values in the MovieList table it should be affect all the table that has the same column TitleMovie....
in Access database I just use the lookup wizard but ofcourse mysql is differnt so can you give me some examples of this query..
I don't think you understand normalisation and references.
It sounds like your first table should have and ID of some type as well as the title. Other tables would then refer to that ID, not to the title. If you need to alter the title, the IDs stay the same and no other tables need to be updated.
