Question:
What is the difference between Left joins and Inner joins in SalesLogix?
Answer:
Inner
and left denotes the type of joins between tables. If you have an inner
join then a record must exist in both tables in order for results to be
returned. If it is a left join then all rows from the parent table will
be returned even if there is not a matching record in the other table.
Select
Account inner join accountsummary on account.accountid=accountsummary.accountid
returns
only records where a matching Accountid record exists in both the account and
account summary table
Select
Account left join accountsummary on account.accountid=accountsummary.accountid
returns all account records even if the
accountsummary table does not have a matching accountid in it.
