SqlDev 3.0 - Query Builder - Drag/Drop table - SLOW

Has anyone else had their sql*dev 3.0 session essentially "freeze" when attempting to drag/drop a table into the query builder tab?
After the table finally show up in the query builder, if I remove the table and then drop it back in again, it appears in the QB immediately. The slowness only seems to happen the first time you drag each individual table in.
Anyone seen it?, is there a solution?
Thanks!

It's expected behavior, since the Query Builder needs to load all the required table meta data and the related constraints, foreign keys etc.
The first EA version of this actually tried to load everything on startup, but then the tool became unusable during the startup phase of Query Builder.

Query builder; list of tables

Hello,
We use BOXIr2. I would like to use query builder to look up some things. But I don't have information about the (system) tables I can query on. I know one of them: CI_INFOOBJECTS.
Is there any documentation about these tables?
Lia

Thanks this was very helpful. I don't think I would have found this myself.
Still, I can't find any helpful queries using query builder. I need an overview of all scheduled jobs which are recurrend. So I know which jobs are scheduled on a regular basis.

1.1 query builder join between tables

In the latest Sql Developer.
I invoke the query builder and select multiple tables that have foreign keys between them. These foreign key relationships appear in the diagram (good job).
How do I make those relationship appear in the SQL that query builder returns to the sql worksheet. I shouldn't have to re-specify them on the where/criteria tab.
It would be nice if these relationships are defaulted in the joining of tables.

I overlayed the pre-release versionsDo you mean you installed in the same directory?
Don't do that.
There's a system directory (sqldeveloper\sqldeveloper\system) which holds settings and everything, which very well might be corrupted to be used for a newer release.
Try deleting it, it will be regenerated at next startup. Or even better: re-install in another directory all together...

How to disable autojoins in query builder

Hello,
When I add several tables to the graphical query builder window in SQL developer I automatically get all possible variants of joins between them. Tables in the database have many foreign keys, and even with a few tables the net of links between them become completely incomprehensible. The only way around that I found is to delete manually all unneeded links after every table addition. Still this is very tedious and inconvenient, and of course with each new table there is a larger number of links to delete. Is it possible to add a table to the query builder without creating any links automatically?
Best regards,
Vladimir.

Hi Vladimir,
There are no preferences to control Query Builder, but rather than beginning a query there via drag & drop of tables/views from the Navigator tree, why not begin instead with the worksheet by typing in something very minimal like:
SELECT * FROM JOB_HISTORY, JOBS, EMPLOYEES, LOCATIONSNext, switch to the Query Builder tab (just the un-joined tables will appear) and add the joins as you wish. The Completion Insight feature can help speed up typing the table/view names, and also avoids a minor performance issue with Query Builder drag & drop.
Hope this helps,
Gary

Query Builder - How to create a link between tables with many fields?

I have many fields in my tables. When the query builder loads the tables, the tables are expanded to accomodate all the fields. Suppose I want to link Table A's Customer ID (the first field in Table A) wiith Table B's Customer ID (the last field in Table B). How can I do that if the last field in Table B are not visible in the screen?
Currently, I create a link in Table A's customer with a random field in Table B. Then I edit the link to create a proper condition. Is there a more efficient way to do this?
Thanks.

Hi woro2006 -
Easiest way is to grab Table A's title bar & drag Table A down the page until the columns you want to link are visible.
FYI, there is an outstanding bug
Bug 10215339: 30EA1: MISSING THE 2.1 RIGHT CLICK OPTIONS ON DATA FIELDS TO CREATE A LINK
to add a context menu on the field for this. That is, Link {context field} to > {other data sources} > {fields from that source}
It is being considered for 3.1, but I have no idea where it will end up in the priority queue.

P.S.: Arghh, Unfortunately, I just tried it and the diagram does not auto scroll while you drag, so there is some guess work/repositioning the view involved.

Tables not in Query Builder table list bug?

In HTML DB version 1.6.0.00.87 we have tables defined in our schema in our workspace. When we create a view and click on the [Query Builder] link, no tables are in the drop down list for our schema. Why? The schema is there. I can go into the SQL Workshop and query the records our of the tables, but they are not listed in the [Query Builder].
I tried this same function but with my workspace at htmldb.oracle.com. The tables in my schema are listed there.
Is this a bug that was fixed in version 1.6.1.00.02?

There is one schema assigned to the workspace. That schema is listed in the pop-up window. Here are the steps I am doing:
1.) Click on SQL Workshop
2.) Click on Create Object
3.) Click on View
4.) The correct schema is listed in the Schema field. There is only one schema in the drop-down list for the Schema field.
5.) Click on [Query Builder]. A separate browser window appears with the correct schema. There is only one value in the drop-down list for the schema. "- Select Table -" is in the TABLE field.
6.) I click on the TABLE field to get a list of tables for the schema. Only "- Select Table -" is listed. No other tables are listed.
I can cancel the Create View and return to the main page of the SQL Workshop. I can click on Tables to see what table are available. I select the correct SCHEMA and see the list of tables.
I tried this in the same version of HTML DB (v 1.6.0.00.87) in a different database ie. a different HTML DB repository and received the same results, missing tables in the pop-up page
I do not know why the tables do not list in the [Query Builder] for the Create View.

Synonym (to table) visibility in Query Builder?

Hello,
I have a schema that contains a table or two, and a bunch of synonyms to other tables in other schemas. In my current Query Builder (1.1.3 MAIN-27.69), I don't see the tables represented by the synonyms -- other available tools show the tables in their visual query builder, so I'm wondering if there is some function to enable this in Oracle's SQL Developer?
Update: to be more specific, the other tool being evaluated (freeware) is QueryReporter, and its visual query builder includes synonym-table links. I'm trying to steer the staff to SQL Developer, but this is a pretty heavily used capability in QR
I apologize if this has been asked before, I searched the Forum but found no hits.

No, we do not support synonyms in the query builder, but you can switch users in the drop list on the top left hand corner.
We have a bug logged for this.

SQL Developer 1.1.0.21.97 Query Builder Table Name List Unsorted

The Query Builder list of table names is unsorted. Should it be alphabetical?

We have a number of outstanding issue for the Query Builder. These will not be updated for the next evaluation release. I agree, alphabetical would be a better approach.

Problem of Query Builder

Hi ,
I am using SQL Developer 1.1.0.23. In this I was trying to use Query Builder. In this I am facing one problem. In our company, we are provided with the view_only schema which are having access to all the objects.
Now while using Query Builder, I want to use the table of the other schema. But Query builder allow only tables owned by the schema with which we are logged in. This is making it virtually useless if we need to create the query like
Select a.col1,
b.co1
from schema1.table_name1 a,
schema2.table_name2 b;
Can we created such query with Query Builder, or do we have any work around for this ???
Regards
Martand Joshi

This is correct. There is a bug logged for this, but at this stage the query builder does not support read only access.

Query builder bug in outer joins ?

I understood that if you were joining two tables A and B, the following was a
LEFT OUTER JOIN
SELECT A.COL, B.COL
FROM A, B
WHERE A.ID = B.ID (+)
ie: a LEFT outer join has the (+) on the Right-hand table.
However, query builder puts the (+) on the Left-hand table.
Same for a RIGHT outer join - I think the (+) should be on the Left-hand table, but query builder puts it on the Right-hand table.
Cheers,
Andrew
(running Version 2.1.0.00.39)

Hi Andrew,
I just played a little with the query builder and created a join between two of my tables:
PROJECTS and ACTIVITIES, linked via KCC.
When I create a left outer join in query builder, I get the following result:
select     "PROJECTS"."KCC" as "KCC"
from     "ACTIVITIES" "ACTIVITIES",
     "PROJECTS" "PROJECTS"
where "PROJECTS"."KCC"(+) ="ACTIVITIES"."KCC"
Which is correct: Left refers to the first table in the from clause (ACTIVITIES) and places the (+) on the other table!
Left and right refers to the order of tables in the from clause, not in the where clause. Query builder sorts the tables in FROM alphabetically, maybe this is differing from the graphical order in query builder.

Oracle Query Builder 2.5 error

May be I'm posting it to the wrong forum but...
I'm getting the error BRW-15954: Oracle Query Builder 2.5 tables are missing or not installed properly when I try to launch Browser. What can I do about it?
Help please!!!
Thanks,

You may have to run some of the scripts located in 'oracle_home\browse25\sql' directory as user 'SYSTEM'.

Version 3.0.04: Query builder shows tables minimized

When we save a SQL statement, and then re-open that file, the view of the SQL from the Query Builder tab shows the tables as "rolled-up", such that, you can only see the table name and the selection box which allows you to pull in all columns from that table. If you drag the bottom edge of the table downward, it just creates an empty box.
You can copy & paste the SQL into a fresh editor window & keep working. So there's a workaround. Unless someone knows how to make the individual columns re-appear in the original Query Builder window?
Thanks,
--=Chuck

Hi Chuck -
I'[m assuming the query(ies) in question are of the form "select *". The Query Builder relies on a connection to the database to get the meta data about fields for the tables. Opening the file, then choosing the appropriate database in the connection drop-down at the right, then switching to Query Builder will show the fields.
(Note that in the current version you must use that order [open, database, query Builder] (or after selecting database, go to worksheet & make a dummy edit [for example, erase/replace something] then switch back to Query Builder. This has been fixed for the next release.)

Inconvenient on drag a table into SQL Builder

When I click on a non selected table to drag it into SQL Builder SQL Developer open it to edit the table instead of dragging it. Is there any way of configure SQL Developer not to act that way ?
Thank you very much.

As I recall, SQL Developer 3.0 and higher let you drag and drop into the Query Builder tab without opening the object browser. If you just drag and drop into a Worksheet, then very old versions may paste in the table's DDL, but in any modern version the DnD behavior should be controlled by
Tools > Preferences > Database > Drag and Drop
Just experiment with that. Remember to click, hold down the mouse button, then drag into the Worksheet.

Query Builder - Tables not Appearing

Hi, I am encountering a problem when trying to use Query Builder.
If I have a table that is joined to by more than one other object and wish to drag TWO instances of this table into Query Builder, it will not allow it to happen. It doesn't give any error message, just at the end of the drag operation, nothing appears.
I've now tried it with a blank canvas and just tried to drag two instances of any table there. It will just not allow the second one to appear.
I am using SQLDeveloper in the following environmeny
OS Name Windows XP (version 5.1)
java version 1.5.0_05
java.vm.version 1.5.0_05-b05
SQLDeveloper version 1.1.2.25
and am connecting to a local version of Oracle Database XE.
Am I doing something wrong or is this a known problem?
Chloe

Thanks. I've requested it as a missing feature, but it seems odd that this functionality is not already there. Using the ubiquitous EMPLOYEE table that all good examples seem to use, you would not even be able to join this table to itself to get the details of managers of employees.
That's why I wondered if it was a bug on my laptop first.
I have taken your advice and created views of the tables I need to have multiple joins to as a workround for now, but I may end up with multiple views of the same table which could get unwieldy.
Thanks again though. :-)

Query Builder - 2 occurrences of same table and Show Related Tables

In SQL Developer 1.5 the Query Builder still does not allow you to drag two copies of the same table onto the canvas. Additionally the Show Related Tables does not appear to do anything even after Hide Related Tables. Both of these operations sets the cursor to the hourglass although you can continue working as if the commands completed OK. Query Builder is a great time saver but with limitations like this it is really hobbled.
Additionally, in order to get join conditions you have to double-click the join in the diagram before the appropriate WHERE clause appears. I have not found any reference to how to use the Query Builder in any documentation. This forum has stated that the Query Builder is supposed to be intuitive and easy to use but this is not the case so far.
The rest of SQL Developer is a pleasure to use!

Thanks for your feedback. There are a number of things we want to do to the Query Builder. The issue about dragging 2 copies of a table onto the work surface is a logged enhancement request that we want to address. The Show Related tables and hourglass issues are bugs and need to be addressed. I'll document those.
Better documentation is also important and we can add that into the product for a future release.
In the short term, I have on previous occasion said I'd do a demo for using the Query Builder, so I'll make that a priority.
