Developing Python-SQLAlchemy Interface, OUTER JOIN/ORDER BY/LIMIT problems
Hi,
We are currently trying to implement a database interface for SQLAlchemy, an object relational mapper (ORM) library for python. (http://www.sqlalchemy.org)
There are some MaxDB-specific issues, we have to sort out for this, so perhaps you can give us some help on the following:
1) Outer joins buggy for MaxDB releases < 7.6.03.07:
When joining more than 2 tables, the database may return incorrect results. Simple modifications of the order in where clauses may give different results (e.g. FROM lhs LEFT OUTER JOIN rhs ON lhs.col=rhs.col vs rhs.col=lhs.col)
For 7.6.03.07, these issues seem to be fixed, however, I could not find any changelog or bugfix-report, which confirm that these bugs are completely fixed.
2) ORDER BY/LIMIT seem not to be supported in subqueries.
3) LIMIT is not supported for derived tables, e.g.:
SELECT * FROM (SELECT * FROM a) LIMIT 2
More detailled information about these issues can be found at:
http://www.sqlalchemy.org/trac/wiki/DatabaseNotes (In section MaxDB/SAP DB)
Can you please tell me if and when these bugs/features will be fixed in future MaxDB releases?
Best Regards,
Hermann Himmelbauer

It's clearly not impossible, just different than you expect. Create your playlist as you want it to appear in the Current tab (meaning don't dump every single song from your library in there, just the ones you want) and then save the playlist.

Look at save_absolute_paths_in_playlists in your mpd.conf.

Tracks out of order and other problems
For one of my albums, the tracks are all out of order. I have edited the information, and the track numbers are proper, but it will not order them correctly. I have even removed the files from Itunes and then added them again--still they do not go in order. Then when I move the files onto my Ipod they are out of order, and it's very annoying. If Itunes won't recognize the track numbers, how do I reorganize them?
My other problem is manly with the Ipod. I'm not entirely sure what I did to cause this but on my Ipod, an artist is doubled. And yet when I view the songs list on Itunes (the list of my Ipod) there is only one artist. How am I supposed to fix this?
I've tried everything I would know of, and neither problems can fix. Thanks to everyone who replies.

Hi
Let's say I have three tables ORDERS, PRODUCT and CLIENT. I want a query that will give me all PRODUCT and CLIENT combinations and the total sum of orders if it has one. If I try to do this:
select P.NAME, C.NAME, SUM(O.AMOUNT)
from PRODUCT P, CLIENT C, ORDER O
where P.ID = O.PRODUCT_ID(+) and
C.ID = O.CLIENT_ID(+)
I get an error where I cannot double outer join a table.

and ANSI allows a little more in those terms than regular oracle syntax.It is different, but it cannot do anything that regular equi-joins cannot do. In most cases the optimizer converts ANSI joins to regular joins for execution, and this additional conversion has been subject to numerous bugs.ANSI does allow for doing things that regular Oracle syntax cannot do.
Here's an ANSI way to do it if you only want to see those client/product combinations that exist in orders table:
SQL> with product as (
2 select 101 id, 'Product 1' name from dual union all
3 select 102 id, 'Product 2' name from dual union all
4 select 103 id, 'Product 3' name from dual
5 ), client as (
6 select 11 id, 'Client 1' name from dual union all
7 select 12 id, 'Client 2' name from dual
8 ), orders as (
9 select 11 client_id, 101 product_id, 10 amount from dual union all
10 select 11 client_id, 103 product_id, 30 amount from dual union all
11 select 12 client_id, 102 product_id, 20 amount from dual union all
12 select 12 client_id, 102 product_id, 20 amount from dual
13 )
14 --
15 -- end-of-test-data
16 --
17 select p.name
18 , c.name
19 , sum(o.amount)
20 from orders o
21 left outer join product p
22 on p.id = o.product_id
23 left outer join client c
24 on c.id = o.client_id
25 group by
26 p.name
27 , c.name
28 order by
29 p.name
30 , c.name
31 /
NAME NAME SUM(O.AMOUNT)
Product 1 Client 1 10
Product 2 Client 2 40
Product 3 Client 1 30(If the datamodel is good with product_id being a foreign key of product.id and the same with client, then outer join is not really necessary, I know. But for the sake of argument assume bad datamodel that needs outer join ;-) )
The above ANSI can be written in regular Oracle syntax as well:
SQL> with product as (
2 select 101 id, 'Product 1' name from dual union all
3 select 102 id, 'Product 2' name from dual union all
4 select 103 id, 'Product 3' name from dual
5 ), client as (
6 select 11 id, 'Client 1' name from dual union all
7 select 12 id, 'Client 2' name from dual
8 ), orders as (
9 select 11 client_id, 101 product_id, 10 amount from dual union all
10 select 11 client_id, 103 product_id, 30 amount from dual union all
11 select 12 client_id, 102 product_id, 20 amount from dual union all
12 select 12 client_id, 102 product_id, 20 amount from dual
13 )
14 --
15 -- end-of-test-data
16 --
17 select p.name
18 , c.name
19 , sum(o.amount)
20 from orders o, product p, client c
21 where p.id(+) = o.product_id
22 and c.id(+) = o.client_id
23 group by
24 p.name
25 , c.name
26 order by
27 p.name
28 , c.name
29 /
NAME NAME SUM(O.AMOUNT)
Product 1 Client 1 10
Product 2 Client 2 40
Product 3 Client 1 30Many old Oracle coders will probably state that this syntax is much easier. For a simple case like this I find both ways easy. But I have complex cases where I much prefer ANSI where I can easily distinguish join predicates from filter predicates. It is a matter of opinion, I know ;-)
But if we then take the original post as a literal specification, that we want all combinations of products and clients and then the sum of order amount if it exists, null otherwise.
This can be written easily in ANSI notation:
SQL> with product as (
2 select 101 id, 'Product 1' name from dual union all
3 select 102 id, 'Product 2' name from dual union all
4 select 103 id, 'Product 3' name from dual
5 ), client as (
6 select 11 id, 'Client 1' name from dual union all
7 select 12 id, 'Client 2' name from dual
8 ), orders as (
9 select 11 client_id, 101 product_id, 10 amount from dual union all
10 select 11 client_id, 103 product_id, 30 amount from dual union all
11 select 12 client_id, 102 product_id, 20 amount from dual union all
12 select 12 client_id, 102 product_id, 20 amount from dual
13 )
14 --
15 -- end-of-test-data
16 --
17 select p.name
18 , c.name
19 , sum(o.amount)
20 from product p
21 cross join client c
22 left outer join orders o
23 on o.product_id = p.id
24 and o.client_id = c.id
25 group by
26 p.name
27 , c.name
28 order by
29 p.name
30 , c.name
31 /
NAME NAME SUM(O.AMOUNT)
Product 1 Client 1 10
Product 1 Client 2
Product 2 Client 1
Product 2 Client 2 40
Product 3 Client 1 30
Product 3 Client 2
6 rows selected.ANSI notation allows outer join with more than one table.
Regular Oracle syntax could only do this by creating an inline view of the cartesian join and then outer joining orders with the inline view. Doable, but not as nice (IMHO) as the ANSI method for a case like this ;-) -
Newbie: Syntax for OUTER joins
Hello there,
I'm trying to write some very simple ANSI outer joins using quest's TOAD software but I keep running into syntax errors.
Take the following classic text book example
Find all customers who have not placed an order
SELECT c.customerid, o.orderid
FROM customers c
LEFT OUTER JOIN orders o
ON c.customerid = o.customerid
WHERE o.orderid IS NULL
alternative syntax supported by SQL Server
SELECT c.customerid, o.orderid
FROM customers c, orders o
WHERE c.customerid *= o.customerid AND o.orderid IS NULL
How do you write the above style of statements. Can you write RIGHT JOIN and FULL JOIN statements? What about CROSS JOIN statements
Cheers,
Colin Rippey
nullSELECT c.customerid, o.orderid
FROM customers c, orders o
WHERE
c.customerid = o.customerid(+) and
o.orderid IS NULL

Query by example and outer join supported?
Does TopLink support outer joins when using query by example and cursored streams? I am having problems getting this to work. It seems to completely ignore the requested outer join.
I have tried several variations of what is below, but have never seen TopLink generate the outer join. This is against Oracle 9i on TopLink 9.0.4.5.
Customer 1->1 Address (using valueholder indirection)
ReadAllQuery q = new ReadAllQuery();
q.setReferenceClass(Customer.class);
QueryByExamplePolicy policy = new QueryByExamplePolicy();
policy.addSpecialOperation(String.class, "like");
q.setQueryByExamplePolicy(policy);
ExpressionBuilder builder = q.getExpressionBuilder();
Expression addressExp = builder.getAllowingNull("address");
q.addJoinedAttribute(addressExp);
q.addOrdering(addressExp.get("city").ascending());
q.useCursoredStream(end-start, end-start);
q.setExampleObject(exampleCustomer);
CursoredStream stream = (CursoredStream)s.executeQuery(q);
...iterate through the stream...
Note, that the database level relationship is expressed through a target foreign key.
( addressMapping.addTargetForeignKeyFieldName("ADDRESS.CUSTOMER_ID", "CUSTOMER.CUSTOMER_ID");)
Any help would be appreciated.
Thanks,
KevinKevin,
I spoke too soon. All you need to do is use the getAllowingNull in the ordering expression and not use the addJoinedAttribute. With this you can use query-by-example with additional outer-joined ordering.
Here is an example based on the Employee demo:
ReadAllQuery raq = new ReadAllQuery(Employee.class);
ExpressionBuilder eb = raq.getExpressionBuilder();
raq.addOrdering(eb.getAllowingNull("address").get("city").ascending());
Employee exampleEmp = new Employee();
exampleEmp.setLastName("%");
// My default constructor populates the period so I'll null them so
// they are not included in the selection criteria of the example object
exampleEmp.getPeriod().setStartDate(null);
exampleEmp.getPeriod().setEndDate(null);
QueryByExamplePolicy policy = new QueryByExamplePolicy();
policy.addSpecialOperation(String.class, "like");
raq.setQueryByExamplePolicy(policy);
raq.setExampleObject(exampleEmp);
List emps = (List) session.executeQuery(raq);
I hope this helps,

Hi Everyone,
I am still in the process of learning SQL, and I am having trouble specifically with the the left outer join. I normally join tables using equijoin's, but I am not getting the right data set returns, and thought the using a left or right outer join would resolve the problem...
Here is my SQL that is working properly with 1 left outer join. I am building the query slowly so in the next SQL you will see where I am seeing the error. I don't expect you to understand the data and columns I am trying to join, I believe the problems I am experiencing are related to syntax, and I am hoping you can find where my syntax errors are.
select
s.name as "Screen Name",
sv.view_name as "View Name",
s_view.name
from
s_screen s,
s_screen_view sv
left outer join s_view
ON (sv.view_name = s_view.name)
where
sv.screen_id = '1-866A-1X3LU' and
s.row_id = sv.screen_id and
s.repository_id = '1-866A-1' and
s_view.repository_id = '1-866A-1';
Here is the SQL where I am experiencing the following error...
Error:
ORA-00904: "SV"."VIEW_NAME": invalid identifier
00904. 00000 - "%s: invalid identifier"
*Cause:
*Action:
Error at Line: 14 Column: 7
Problematic SQL:
select

sv.view_name as "View Name",
s_view.name,
s_applet.name as Applet
--a.name as "Applet Name"
from
s_screen s,
s_screen_view sv,
s_view_wtmpl_it wti
left outer join s_view
ON (sv.view_name = s_view.name)
left outer join s_applet
ON (wti.name = s_applet.name)
where
sv.screen_id = '1-866A-1X3LU' and
s.row_id = sv.screen_id and
s.repository_id = '1-866A-1' and
s_view.repository_id = '1-866A-1';
Thanks in advance for your help.

s.row_id = sv.screen_id
"Oracle style" or "old style" joins have commas between tables in the FROM clause, and the join conditions are all in the WHERE clause. They do not use the keywords JOIN or ON.
ANSI style joins have the keyword JOIN between tables (sometimes accompanied by other keywords, such as LEFT, OUTER or CROSS), and the join conditions are given in the FROM clause, usually after the keyword ON.
The first example you gave is an ANSI style join. It has the JOIN keyword, not a comma, between tables.
The second example you gave:
s.row_id = sv.screen_id
could be part of either. It could occur in an ANSI join (in the FROM clause, after the keyword ON), or it could occur in an old-style join (in the WHERE clause). -

OBIEE not applying outer join syntax to filters
(Note: I've already thoroughly searched the forums before posting this. Thanks)
My problem is the following:
I'm trying to build a report that is a count from my fact table, grouped by month from my date dimension for a given year, resulting in 12 data points. The problem is that not all months have actual data, but I still need those months to show on the report with a count of zero. Typical simple reporting requirement.
I have already done the obvious and within my business layer made the join between my fact table and my date dimension an outer join on the fact side, just like you'd do if writing the query by hand. And when tested by hand this includes all dates for the year anyway, and when coupled with the appropriate null test on the count measure I'd get my 12 data points with zeros were appropriate.
The problem is that there are additional filters I need to apply on the fact data (there are a couple text-based code values that didn't warrant full tables themselves so are just degenerate dimensions directly on the fact table.)
When these filters are applied at the Answer level, I'm only getting back the months that actually have data, and lose the months where the count should be zero. A check of the session log for the query that was generated shows the problem. While OBI properly generates the outer-join syntax for the join itself between the two tables (my date dim and fact table) it does NOT apply the outer-syntax to the constant-based filter against the fact, effectively negating the outer join.
Actual query from the log (I simply changed the table aliases from the ugly T##### stuff OBI generates to something more readable for posting here):
select D.DT_MONTH_NAME as c1,
D.DT_MONTH_NUM as c2,
I.INC_TYPE as c3,
I.INC_EMP_GROUP as c4,
sum(case when I.INC_KEY is null then 0 else 1 end ) as c5
from DATE_DIM D, INCIDENT_F I
where ( D.DATE_KEY = I.DATE_KEY (+) ) and ( D.DT_YEAR = 2010 and I.INC_EMP_GROUP = 'CONTRACTOR' )
group by D.DT_MONTH_NUM, D.DT_MONTH_NAME, I.INC_TYPE, I.INC_EMP_GROUP
order by c2
You can see that the outer syntax (+) is applied to the join, but not to the filter on I.INC_EMP_GROUP. If I take this query and drop it in something like SQL Developer, it only returns the months with data. If I throw the (+) after I.INC_EMP_GROUP like I'd do if writing this by hand, the desired zero-months results pop back in.
I have already searched the forums and while lots of people seem to have asked this question, the only solutions involve things like trickery in the business layer using dummy fact tables followed by manipulations at the report level etc. Unfortunately I can't rely on these as the system is eventually to be turned over to users who can't be expected to apply various hacks to write reports.
Anyone ever get to the bottom of getting OBI to apply outer join logic in filters as well, when the filtered table is meant to be outer-joined to?
Any comments are appreciated.
JohnI know that this thread is a bit old thought it might be helpful to some one...
The Issue is, when using Degener@teDimen$ion ( this is !nner joned to FACT tables in BMM) and if any of the dimensions {other than theDegener@teDimen$ion (Let us say Dim X) } have an ()uter join to any of the fact tables, and you were doing your analysis using Degener@teDimen$ion, Dim X, Measure value you will face the following issues.
when filtering the analysis on the ()uter join dimension ( Dim X), the IN filter will not work. Reason is that the filter is getting applied to both the Dimension and FACT tables and the values that exist in Dimension Dim X but not in FACT table wont show up.
The above issue can be fixed by changing the join between the fact and Degener@teDimen$ion from inner to outer. I think this is a bug.. because it is supposed to filter the fact table after the entire outer joined result is obtained but not filter the fact table for the Dim X values and do a outer join. I think the BI should be intelligent enough. -
How to use outer join to display the results
I want to develop a report in which the column sequence will be as follows:
1)Item_code
2)Item_name
3)Stock
4)Pending
5)Re-order Level
6)Item_reorder_qty
I had written the query, but the problem is all the products does not get displayed. The products are more than 700. But after running the query, only 364 gets displayed.
How i can make use of outer join in the following statements :
AND ITEM_CODE = LCS_ITEM_CODE
AND ITEM_CODE = PI_ITEM_CODE
AND LCS_ITEM_CODE = PI_ITEM_CODE
in the below given query to solve this.
SELECT
ITEM_CODE,
ITEM_NAME,
((LCS_STK_QTY_BU + LCS_RCVD_QTY_BU - LCS_ISSD_QTY_BU- LCS_REJECT_QTY_BU)/IU_MAX_LOOSE_1)STK ,
SUM(TO_NUMBER(PI_QTY||'.'||PI_QTY_LS) - (PI_GI_QTY_BU/IU_CONV_FACTOR/IU_MAX_LOOSE_1))PNDG,
ITEM_RORD_LVL,
ITEM_RORD_QTY
FROM
OM_ITEM,
OM_ITEM_UOM,
OT_PO_HEAD,
OT_PO_ITEM,
OS_LOCN_CURR_STK
WHERE (ITEM_UOM_CODE = IU_UOM_CODE AND ITEM_CODE = IU_ITEM_CODE)
AND ITEM_CODE = LCS_ITEM_CODE
AND ITEM_CODE = PI_ITEM_CODE
AND LCS_ITEM_CODE = PI_ITEM_CODE
AND LCS_LOCN_CODE ='RM'
AND PI_PH_SYS_ID = PH_SYS_ID
GROUP BY ITEM_CODE,ITEM_NAME,LCS_STK_QTY_BU,LCS_RCVD_QTY_BU,LCS_ISSD_QTY_BU,LCS_REJECT_QTY_BU,IU_MAX_LOOSE_1,ITEM_RORD_LVL,ITEM_RORD_QTY
ORDER BY ITEM_CODE ASC
YogeshAs you have no table aliases I can't tell what columns relate to which tables on your join conditions.
Can you not just put (+) next to the outer joined columns you require on the where clause? Or perhaps consider using ANSI syntax for the joins such as <tableA> LEFT OUTER JOIN <tableB> ON (<join conditions>) -
LEFT OUTER JOIN, Problem in POST-QUERY TRIGGER
Hi,
Please guide for the following
I wrote below query in POST-QUERY Trigger of a TABULAR DATA BLOCK, having only one text item, called INVENTORY_ITEM
select c.cat||' '||s.subcat||' '||l1.lvl1 ITEM INTO :DATABLOCK.INVENTORY_ITEM
from itemcat c
LEFT OUTER JOIN itemsubcat s on (c.catid = s.catid)
LEFT OUTER JOIN lvl1 l1 on (s.subcatid = l1.subcatid)
When I compile the module an error is generated
*" Encountered the symbol 'LEFT' when expecting one of the following ,; for group having intersect minus order start union where connect ".*
Above query is working fine in ORACLE SQL DEVELOPER .
Any solution please.

Obtaining the list of data interfaced out of SAP HCM
Hello,
we got a good challenge from our partners in the business organization that we support. The Data Privacy officer on the business partner side would like to know:
- what other systems are "takers" of the data from our SAP HCM instance
- what data pieces (what tables, fields...) are being interfaced out
- what is the frequency of that
We are trying to maintain the document whenever a new interface is being built but in practice you know how it looks like.In order to have 100% confidence in the anwser I would want to pull such list from the system. Is there a way to do that? What would you suggest?
Regards,
PawelTry the function below, pass the item name and get the Data provider for that particular item, you will have to do this for all the items in the template.
function getDPName(item){
prop = SAPBWGetItemProp(item);
var tableHidden=true;
if (prop != null){
for(i=1;i<prop.length;i++){
if (prop<i>[0] == "DATA_PROVIDER")
return prop<i>[1]
}//end for
}//end if
}//end function
Thanks. -
Hi All,
The issue may be silly, but we cant make it out:
DB : Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - ProdWe are running the below query with no issues:

Thanks,
JeneeshNot sure what is wrong with your version. It might have to do with row_number not working on an empty row (outer joined).
How about this alternative?
The approach is a bit different, but it uses only one access to the user_source view.
select s.lineNo, min(s.text1) text1, min(s.text2) text2, decode(upper(min(s.text1)), upper(min(s.text2)), 1, 0) flag

Left Outer Join with more than two tables in both CR 8.5 and XIR2
I am trying to create a report and I have tried two versions of Crystal but I ultimately need the report in CR8.5 for compatibility with the client's system. I think I am starting to figure out what might be wrong and it might be my understanding of SQL, but I can't see why someone hasn't needed this in the past. Ultimately I want to see all projects and any journal entry that might be posted for that project.
Database is MySQL 5.0.38 and using MySQL ODBC driver 3.51.19.
Project header table information will be populated. Each line item on a journal entry can be tagged with the project ID. But for me to pull the journal entry date I need also to link to a third table for the journal entry header info.
I want to see all projects, whether a journal entry has been posted or not.
So the links are like this
ProjectHeader --->Left Outer Join ---> JELines ---> Inner Join ---> JEHeader
I think in this scenerio Crystal is treating the LOJ as an IJ.
I created two brand new reports today, one in CR8.5 and one in CR XIR2. Once I edited the automatic CR8.5 SQL statement (which I have been doing for years, usually without problem), they both ran properly. I linked customers to their invoices. Customers without invoices showed properly. But then I linked the invoices to the payments of the invoices and immediately lost customers without orders in both reports.
So apparently only two tables are allowed in Outer Joins. Does this make sense? I checked out the w3schools tutorial on SQL and it doesn't mention this limitation and I can't find anywhere else that it specifically indicates this but all samples of code I have seen only show two tables. I just thought for presentation as a sample that was easiest to understand and we could expand as necessary.
If this is correct, how does one go about accounting for this kind of thing? One solution that goes through my mind is creating a view at the database level for the link between journal entry lines and journal entry headers. Would this be a good solution under normal circumstances?
A second option that I had to implement because of timelines, is to use a subreport linked to the main report through the project ID to pull the information for the journal entries and just pass the totals I need to the main report through a shared variable.
These aren't normal circumstances because I don't have access to the database so I can't create the view. I have come across this concept several times and I have been able to use subreports to solve it but I am trying to find a better solution for the future as sometimes subreports can be slow. So are there any alternatives I have not considered here?
TIA rasincSo after some more work and another post. I was able to get this to work.
Items disappear when linking to another table
My issues were two fold. I was selecting on the tables on the right-side of the original Inner Join. However, I was checking for Nulls. This apparently is correct but you must check for the Nulls first eg. (IsNull (JEHeader.Field1) OR JEHeader.Field1 <= 100). I had my original statement reversed checking for <= 100 before checking for Nulls.
I also did not set all links to be Left Outer Join. I had the Inner Join. I actually have about 6 tables in this report so all the links need to be set Outer Join. So this now seems to be corrected.

OUTER JOIN -- Error: ORA-01417 (a table may be outer joined to at most one
Hi there,
I have a rather simple task: retrieve all the records in a table, for agiven domain p_domain_id (input parameter). The problem is that there are about 6 FKs in the table, and I need the names (strings) corresponding to those FKs (from other tables). Unfortunately, some of the FKs are NULL, so in '=' I loose records. Without the last 2 lines in WHERE clause, I get the correct result. With d2 in place (and without the "(+)" ) I loose 2 records. With the d3 (and also without "(+)"), I do not get any record.
With the "(+)", the code compiles but I get the run time error ORA-01417
NOTE: I put the "+" within parentheses, in order to show it like a text in this editor.
What's an elegant solution to this?
Thanks a lot.
Here's the code:
SELECT
a.DOMAIN,
b.NAME,
a.DE_ID,
a.NAME,
a.PREFERRED_LABEL,
a.TECHNICAL_DEFINITION,
a.PUBLIC_DEFINITION,
a.DE_TYPE,
c1.NAME,
a.HAS_PARAMETER,
a.VALUE_CLASS,
c2.NAME,
a.INDEX_TERMS,
a.DATA_TABLE_ID,
d1.TABLE_NAME,
a.SP_INSERT,
a.SP_UPDATE,
a.SP_GET_BYMRN,
a.SP_GET_BYATTRIBUTE,
a.VALUE_TABLE_ID,
d2.TABLE_NAME,
a.PARAM_TABLE_ID,
d3.TABLE_NAME,
a.PARAM_DOMAIN_LOGIC,
a.SP_LOV,
a.LOWER_LIMIT,
a.UPPER_LIMIT,
a.BOOLEAN_Y,
a.BOOLEAN_N,
a.COMMENTS,
a.ENTERED_BY,
commons_API.get_person_full_name(a.ENTERED_BY),
a.ENTERED_ON
FROM
DATA_ELEMENT_INDEX a,
DE_DOMAIN b,
GENERAL_LIST c1,
GENERAL_LIST c2,
TABLE_GROUP d1,
TABLE_GROUP d2,
TABLE_GROUP d3
WHERE
DOMAIN = p_domain_id AND
b.DOMAIN_ID = a.DOMAIN AND
c1.ID = a.DE_TYPE AND
c2.ID = a.VALUE_CLASS AND
d1.TABLE_ID = a.DATA_TABLE_ID AND -- it works well without the next two lines
d2.TABLE_ID = a.VALUE_TABLE_ID "(+)" AND
d3.TABLE_ID = a.PARAM_TABLE_ID "(+)"
ORDER BY a.NAME;

Oracle syntax does not support outer joining to more than one table.
However ANSI syntax does...
