Hi Matthew,<br>
<br>
You'll need to mark the vtkSQLDatabaseTableSource instance as modified in order for Update() to re-execute the pipeline; otherwise, it will return the previous results. For example, just after "//add values to table", add<br>
<br>
databaseTable->Modified();<br>
<br>
and you should see the new values.<br>

Hi,<br>
<br>
Does vtkSQLDatabaseTableSource have the ability to update and re-execute the sql query?<br>
<br>
<code><br>
vtkTable* table;<br>
VTK_CREATE( vtkSQLDatabaseTableSource, databaseTable );<br>
databaseTable->SetURL("sqlite:<u></u>//database.db");<br>
databaseTable->SetQuery("<u></u>SELECT * FROM MYTABLE");<br>
table = databaseTable->GetOutput();<br>
table->Update();<br>
table->Dump();<br>
<br>
//add values to table<br>
<br>
table->Update();<br>
table->Dump();<br>
//does not contain the new values<br>
</code><br></div></div>
