How to generate ANSI SQL syntax mapping
I am not able to force OWB to generate ANSI SQL syntax mapping.
In mapping configuration I have checked "ANSI SQL syntax" On, "Operating mode" is "Set based fail over to row based", "Optimize code" is On.
"PLSQL generation mode" is set to 10gR2.
OWB 10.2.0.4.36, OraDB 10.2.0.4.0
Oracle SQL is based on ANSI sql 92 standards. But not possible to generate queries in ansi sql 92 format?

Generate ANSI SQL with Oracle IKM
Is it possible for ODI to generate ANSI SQL with the Oracle IKM?
I have used ANSI joins in a filter in an interface, now when I run the interface I get the error: ORA-25156: old style outer join (+) cannot be used with ANSI joins.
I would prefer to use ANSI joins in my filters instead of the old style (+) syntax. Is this possible?Sure,
Go to topology, edit your Oracle technology , on SQL tab change it over to ordered joins - clause location - From , you can specify the keywords left join, right join, full outer join etc to get rid of your '(+)' -
ANSI SQL Syntax - What belongs to join-clause and what to where-clause
Hello,
we currently have a discussion about the ANSI SQL Syntax where we do not agree what belongs to the join clause and what belongs to the where clause in an ANSI Sytnax SQL Query.
Lets say there is a query like this:
+SELECT *+
FROM employees emp, departments dept
WHERE emp.dept_country = dept.dept_country
AND emp.dept_name = dept.dept_name
AND dept.dept_type = 'HQ'
AND emp.emp_lastname = 'Smith'
Primary key of the departments table is on the columns dept_country, dept_name and dept_type. We have a Oracle database 10g.
Now I have rewritten the query to Ansi Syntax:
+SELECT *+
FROM employees emp
JOIN departments dept
ON emp.dept_country = dept.dept_country AND emp.dept_name = dept.dept_name
WHERE dept.dept_type = 'HQ'
AND emp.emp_lastname = 'Smith'
Another developer says that this is not completely correct, every filter on a column that belongs to the primary-key of the joined table has to be in the join clause, like this:
+SELECT *+
FROM employees emp
JOIN departments dept
+ON emp.dept_country = dept.dept_country AND emp.dept_name = dept.dept_name AND dept.dept_type = 'HQ'
WHERE emp.emp_lastname = 'Smith'
Can somebody tell me which on is correct?
Is there any definition for that? I couldn't find it in the Oracle Database definition.
I just found out the names of the ANSI documents here: http://docs.oracle.com/cd/B19306_01/server.102/b14200/ap_standard_sql001.htm#i11939
I had a look at the ANSI webstore but there you have to buy the PDF files. In my case thats exaggerated because both of the Queries work and i am just interessted if there is one correct way.
Thank you in advance
MarcoHi,
As i guideline i would say, answer the question: should the result of the join be filtered or should only filtered rows be joined from a particular table?
This is helpful in the case of outer joins also, for inner joins it doesnt matters as said already be former posters, where there may be hughe semantical differences depending of where the predicates are placed.
From performance view, if we talk about oracle, take a look a the execution plans. You will see that there is (probably) no difference in case of inner joins. Even in case of outer joins the optimizer pushes the predicate as a filter towards the table if it semantically possible.

Hi all,
I have a simple query
SELECT A.*, B.Dstrct_Code FROM MSF601 A, MSF600 B
WHERE ALTERNATE_REF LIKE 'PF%'
AND A.alt_ref_code = B.Equip_No
AND B.Dstrct_Code = 'ACME';
which works fine, but I want to convert it to ANSI
SQL syntax, so I tried
SELECT A.*, B.Dstrct_Code FROM MSF601 A, MSF600 B
WHERE ALTERNATE_REF LIKE 'PF%'
INNER JOIN ON A.alt_ref_code = B.Equip_No
AND B.Dstrct_Code = 'ACME';
but I get
ERROR at line 3:

Could some kind soul explain why?
Paul...An example that looks a lot like your example:

7 /
inner join on dept.deptno = emp.deptno

Hi,
Is there a performance difference between ansi and old syntax.
The following query
SELECT ITD.display_description
FROM structure_child SC
RIGHT OUTER JOIN structure S ON SC.structure_id = S.structure_id
INNER JOIN structure_level SL ON SL.structure_level_id = S.structure_level_id
INNER JOIN item_type_naming ITN ON ITN.structure_id = S.structure_id
INNER JOIN item_type_description ITD ON ITN.item_type_description_id = ITD.item_type_description_id
AND item_type_id = p_item_type_id
WHERE ( S.structure_id = p_structure_id OR S.structure_id = 0)
and itd.item_type_id = p_item_type_id
ORDER BY structure_level
Runs much slower than the old style query
SELECT ITD.DISPLAY_DESCRIPTION
FROM structure S, structure_child SC, structure_level SL,item_type_naming ITN,
item_type_description ITD
WHERE SC.structure_id(+) = S.structure_id
AND SL.structure_level_id = S.structure_level_id
AND ITN.structure_id = S.structure_id
AND ITN.item_type_description_id = ITD.item_type_description_id
AND item_type_id = p_item_type_id
AND (S.structure_id = p_structure_id OR S.structure_id = 0)
ORDER BY structure_level
Any reasons why this is the case. Also is there any hint I can give to improve the performance.They ought to be the same.
Be sure to run the query twice to ensure the extra time doesn't including parsing, etc.
Do you get the same results?
Are the explain/execution plans the same?
The only caveat I can think of with ANSI joins is that there is a problem using them over a dblink in which one of the remote tables has a LOB column, an error is generated it that case...

Hey,
one of my colleagues managed to create a SQL-statement (in ansi-sql-syntax) that just blocks the session and gives no response at all.
When I rewrote the statement, it gave results within a second.
It's not quite possible to provide a sample-case, but maybe someone here has an idea why the first statement doesn't work, and the second does?
First:
====
SELECT c.CONTRACTID as ENTITEITID,
v.VASTSTELLINGCODE,
'' as INFO,
v.CAMPAGNE
FROM NFD_CONTRACT c
INNER JOIN NFD_OVK o ON o.OVKID = c.OVKID
INNER JOIN NFD_VSTDEFCMP v ON v.VASTSTELLINGCODE = 'C77' AND v.CLASSIFICATIECODE = o.CLASSIFICATIECODE AND v.CAMPAGNE = o.CAMPAGNE
AND Nfd_Vaststellingen_Pck.NFD_IS_DATUM_VST_VALID('C77',o.CAMPAGNE,'Contract',o.CLASSIFICATIECODE) = 1
INNER JOIN NFD_BETROKKENPSN_CON psn ON c.CONTRACTID = psn.CONTRACTID
INNER JOIN (SELECT a.aangifteid, a.psn_nmr, a.psnrolid, a.oogstjaar,
case when exists (SELECT ENTITEITID FROM NFD_VST_OA04_V vst WHERE a.AANGIFTEID = vst.ENTITEITID) then 1
when exists (SELECT ENTITEITID FROM NFD_VST_OA05_V vst WHERE a.AANGIFTEID = vst.ENTITEITID) then 1
when exists (SELECT ENTITEITID FROM NFD_VST_OA06_V vst WHERE a.AANGIFTEID = vst.ENTITEITID) then 1
else 0
end AS OA_Heeft_E
FROM NFD_AANGIFTE a
WHERE AANGIFTETYPE = 'Oogstaangifte') vst ON psn.PSN_NMR = vst.PSN_NMR AND psn.PSNROLID = vst.PSNROLID
AND o.CAMPAGNE = vst.OOGSTJAAR AND vst.OA_Heeft_E = 1
Second:
======
SELECT c.CONTRACTID as ENTITEITID,
v.VASTSTELLINGCODE,
'' as INFO,
v.CAMPAGNE
FROM NFD_CONTRACT c
,nfd_ovk o
,nfd_vstdefcmp v

AND psn.PSN_NMR = vst.PSN_NMR AND psn.PSNROLID = vst.PSNROLID
AND o.CAMPAGNE = vst.OOGSTJAAR AND vst.OA_Heeft_E = 1hey riedelmie,
off course the second statement is different.
I rewrote the query so the inner joins are being replaced by where-clauses with the table-names all in the from-clause.
In the second statement there are two extra when-clauses but they should also be in the first statement (the problem is still there, so data could indeed be different, but the problem is the same)
Tnx.
Greetings,
Dave

Hi,
I would like to know how to generate orm.xml, the mapping file for JPA. I am using jdev 10.1.3.0.4.
Thanks in advanceThere is not yet any built in support for this.
What I have been doing is configuring JDev to understand the orm.xml schema so that when editing the file with JDeveloper it can assist me on the available elements and attributes as well as a default structure.
JDeveloper :: Tools -> Preferences -> XML Schema -> Add
jar:file:/C:/oracle/10.1.3.1/preview/jdev/toplink/jlib/toplink-essentials.jar!/orm_1_0.xsd
Now when you wish to create an orm XML instance document in your project you can use:
New -> General -> XML -> XML Document from Schema
Select "Use Registered Schema"
Select the ORM target namespace: http://java.sun.com/xml/ns/persistence/orm
This will give you a basic orm.xml file properly configured which you can then use to define your mappings.

Hi there,
I'd like to be able to capture entire SQL that gets executed when our software creates Oracle schema. In this way we can get a SQL script, which then can be executed separately. Can I achieve that with Oracle Enterpreise Manager or any other Oracle client component ?
If so, could you tell me how to do that ?
Thank you.You don't say which version of the database you are using. If it's 9i then you should check out the DBMS_METADATA package. Otherwise, it is possibly to generate the SQL from the data dictionary (ALL_TABLES, ALL_INDEXES, etc) but that's kind of complicated.
Your best option if you want everything is to use the EXPORT utility with this parameter setting ROWS=N.
If you only want a few objects then TOAD has some neat facilities. Not only can TOAD export DDL scripts, it also allows us to capture the SQL and produce scripts from the worksheet. Probably other SQL tools have similar functionality.
Of course, there's no substitute for writing scripts and storing them in source control in the first place.

How to generate synthetic rows (raw(16) guid cols) in one SQL statement?
We're populating a table containing two GUID columns:
create table object
( object_guid raw(16) primary key
, project_guid raw(16)
)All object GUIDs are unique (thus the PK), and each object belongs to a given project (should be a FK to some project table). We want N objects / rows, belonging to only 100 projects, i.e. 1% of the rows of the object table belong to the project #1, 1% to #2, etc...
Right now we're using about 25 lines of C++/OCI code to do that (one query doing a "select sys_guid() from dual", and using the generated GUIDs to do inserts into object), but I suspect it's possible to do this using a single SQL statement using mysterious connect by or some other Oracle SQL magic. (our OCI code does quite a few round-trips to do the equivalent).
Would anyone please demonstrate how to generate the rows as explained above, and possibly describe how it works for the non-initiated?
Thanks, --DD
PS: I'm sure it can be done in PL/SQL as well, but I'm interested in a SQL version if one's possible.I've found two ways, both taking a few SQL statements, but somehow I think this ought to be possible without intermediary tables... I'm sure there's a better way.

How to generate XML file from SQL file !
I am new to XML publisher. I known one way to generate XML file is register one report file in concurrent manager.
But I want to generate XML file from sql file.
Could someone show me how to code in sql file, how to register is in concurrent manager.
Thanks !Hi
Phew ... not sure we have the space here. So I can point you in the right direction:
1. XML data generation - there are two packages in the db you can use with a plsql procedure, XMLGEN and SQL XML. You can also use java APIs too. Try checking the db documentation and search for the above methods.
2. Registering the report - the system administrators guide will provide this info. Hooking the program up with XMLP is covered here - http://www.oracle.com/technology/products/applications/publishing/resource/CM%20Whitepaper5.0.pdf
