<h4>3. Browse a Table<br>
|
|
</h4>
|
|
Select the menu item "New Table Browser" from "File" and choose
|
|
"EMPLOYEE" as the table you want to browse:
|
|
<p><img style="width: 317px; height: 214px;" alt="" src="dbs5.gif"><br>
|
|
<br>
|
|
</p>
|
|
<p>A Table Browser appears showing the rows
|
|
of table EMPLOYEE.</p>

</p>
|
|
<h4><br>

</h4>
|
|
<h4><br><br>

|
3. Browse related Rows</h4>
|
|
Select the "Children" item from the "Related Rows" drop-down menu and
|
|
choose "EMPLOYEE on inverse-BOSS".<br>
|
|
<br>
|
|
<img style="width: 946px; height: 522px;" alt="" src="dbs8.gif"><br>

Another Table Browser appears showing the subordinates of each Employee
|
|
(the inverse of the "BOSS" relationship)<br>

<h4>3. Generate SQL-Query</h4>
|
|
Within each table browser, a SQL-Query can be generated which selects
|
|
exactly the browser's content.<br>
|
|
Essentially it's a join of all the tables in the navigation
|
|
chain.
|
|
<p>Close the second "EMPLOYEE" browser, navigate from
|
|
EMPLOYEE to PROJECT_PARTICIPATION, and from there to PROJECT.</p>
|
|
<p>Choose "<span style="font-style: italic;">Query
|
|
Builder</span>" item from the "<span style="font-style: italic;">SQL/Query</span>" menu in
|
|
the "PROJECT" browser:</p>
|
|
<p><img style="width: 601px; height: 370px;" alt="" src="dbs9.gif"></p>
|
|
<p><br>The Query Builder form lets you save the query
|
|
into a file, copy it to the clipboard or even execute it.<br>
|
|
Choose "Execute" to get a query-result browser:</p>
|
|
<img style="width: 990px; height: 667px;" alt="" src="dbs10.gif"><br>
|
|
|
|
<p><br>Within this query-result browser, you can edit the
|
|
query anyway you want.<br>
