Once a join is added
to a query, you can change the join by selecting it in the workspace,
right-clicking, and changing the join type or removing the join condition.
You can also change
a join by clicking the
Joins tab, and then
selecting the row in the table. You can make the following changes:
-
add and remove tables from the
join list
-
reorder the sequence of joins by
moving them up or down
-
switch the left table and right
table assignments for a join
-
add, remove, and change the columns
that are used in the join condition
The
Joins tab
shows the join condition for the entire query. Make sure that you
select a row in the upper table to set the columns in the
Join
conditions area.
The workspace shows
a link between the tables that are used in a join. If you specify
a left join or right join, the Venn
diagram icon reflects which table provides the bulk of the data. If
you rearrange the tables in the workspace (switching the left table
and right table), the Venn
diagram icon continues to reflect which table provides the bulk of
the data. In order to change the data relationship, use either of
the following methods:
-
Switch the left table and right
table by selecting a row from the table, and clicking
.
-
Change the join type from left
to right or from right to left.
