    1. COSelect * from documents d left join SR s on d.relationid = s.SRId left join Events e on d.relationid = e.EventId where (s.CustomerId = 123 or e.SRID=s.SRID) . Left join will fetch the not matching records from opposite table.<br> Select * from documents d inner join SR s on d.relationid = s.SRId inner join Events e on d.relationid = e.EventId where (s.CustomerId = 123 or e.SRID=s.SRID) // or will fetch customerid's equal in both SR and Events table.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
