When I enter the hydrant
serial number and location, I want access to automatically enter this data in
the maintaince table and flushing order table.
well, normally you wouldn't. following the rules of data normalization, you
would list the location of each fire hydrant only once - presumably in a
table that lists all hydrants that your station (?) is tracking. assuming
that the serial number of each hydrant is unique, that field can serve as
the Hydrant table's primary key. to link the records in another table to
specific hydrant records, you would add the HydrantSerialNumber field to the
other table as a foreign key, join the two tables on that common field in
the Relationships window, and enforce referential integrity. you can put
both tables in a query any time that you want to show the hydrant location
in combination with data from a related table.
also, usually when you add records to a "parent" table such as Hydrants, you
don't *automatically* add a record to a "child" table such as Maintenance.
you only add a record to a child table when you need to record data that is
specific to that table. and you normally do not enter any data directly into
a table via datasheet view - you enter data via forms.
can you explain your table/relationships in a bit more detail, as well as
what you want to accomplish, so we can suggest a workable solution (or two,
or three)?
