Sys_connect_by_path_node ? [Can do this in ANSI SQL-99] - Hierarchy Query
Hi All,
A slighly more complex connect by problem (that can be done with ANSI SQL-99) looking for an oracle matching output.
Input Data: (Small example subset)
RootID | Parent_ID | FreeText
0 | 0 |
444 | 555 | ABC1
555 | 666 | DEF2
666 | 777 | GHI3
888 | 0 | JKL4
Output Wanted: (Small example subset)
RootID ParentID FreeText LEVEL (Nesting)
444 | 555 | | 1
444 | 666 | ABC1 | 2
444 | 777 | DEF2-ABC1 | 3
444 | 888 | GHI3-DEF2-ABC1 | 4
444 | 0 | JKL4-GHI3-DEF2-ABC1 | 5
Can be easily enough done with ANSI-99 SYNTAX (Not supported in Oracle using a recursive CTE)
Target platform Oracle 9i
ANSI-SQL 99 Syntax: (Not Supported on Oracle - but demonstrates the ANSI-SQL 99 compliant way of doing this)
;WITH Recurse(RootId, ParentID, FreeText, Level) AS
(SELECT td.RootID, td.ParentID, '' as FreeText, 1 as Level
from TEST_DATA td
where rootid = 444
union all
select Recurse.RootID, td2.ParentId, td2.freetext + '-' + recurse.freetext, recurse.level+1 as level
from TEST_DATA td2
select * from Recurse;
The problem: is to generating the freetext component correctly with oracle.
Can generate the freetext component the wrong way round using SYS_CONNECT_BY_PATH.
select connect_by_root(td.RootID), td.ParentID,
CASE when level = 1 then ''
ELSE
SYS_CONNECT_BY_PATH(td.freetext, '-')
END as FreeText, level
from test_data td
connect by td.RootID = prior td.ParentID
which gives:
RootID ParentID FreeText LEVEL (Nesting)
444 | 555 | | 1
444 | 666 | ABC1 | 2
444 | 777 | ABC1-DEF2 | 3
444 | 888 | ABC1-DEF2-GHI3 | 4
444 | 0 | ABC1-DEF2-GHI3-JKL4 | 5
The problem is the freetext component is the wrong way round (the root node information always comes first).
Tried looking at running something like:
select connect_by_root(td.RootID), td.ParentID,
CASE when level = 1 then ''
ELSE
td.freetext || '-' || FreeText2
END as FreeText2, level
from test_data td
connect by td.RootID = prior td.ParentID
--> but unfortunatly the aliasing of the column cannot be used to perform this operation [cannot reference the aliased column FreeText2].
Is there a sys_connect_by_path_node? (The opposite of sys_connect_by_path)
Returns the path of a column value from node to root,
with column values separated by char for each row returned by CONNECT BY condition
Or another way to get to the output required?
Best Regards,
D
Not directly but there is a fairly common workaround using the undocumented REVERSE function.

Error in Migration Db sql server to sql Azure, how i can fix this errors
I get an error TOTAL_WRITE is not supported in current version when i try validate my database from sql server migration in to sql azure. How I can Fix this error migrate to sql azure
Also I git this error sp_spaceused is not supported in current version of Azure SQL Database – Reynel Useche Velasco 22 mins ago
StoredProcedure [dbo].[p_sizetables] -- 'db_name(' is supported only for the local database. You should test to verify the results are what you want. – Reynel Useche Velasco just now edit
Reynel Alfredo Useche VelascoHi Reynel,
I see that you have posted this query on stack overflow.
I would like to involve our SQL experts in this topic and get the best solution.
As of now to my knowledge @@TOTAL_WRITE is not supported on SQL Azure.
In the meantime, you can refer the below links for migrating your database from on-prem to Azure.

Instead of the humongous where clause, put the applicable conditions on the join.
You have

and trim ("F0006". "MCRP22") =: Establishment
and trim ("F4101". "IMSRP1") =: Division
INSTEAD try something like
from JOIN "PRODDTA". "F0101" "F0101" ON "F42119". "SDAN8" = "F0101". "ABAN8"
JOIN "PRODDTA". "F42119" "F42119" ON "F0006". "MCMCU" = "F42119". "SDMCU"
JOIN "PRODDTA". "F4101" "F4101" ON join condition
JOIN "PRODDTA". "F0006" "F0006" ON join condition.
Not sure exactly how you need things joined, but above is the basic idea. Remove criteria for joining the tables from the WHERE clause and put them
in the join statements. That might clean things up and make it more efficient. -
Differences between ANSI SQL and Oracle 8/9
Hallo,
i'm looking for good online texts or books concerning the problem "Differences between ANSI SQL and different database implementations (ORACLE, Informix, MySQL...)" I want to check a program written in C (with ESQL) that works with an Informix-DB. In this code i want to find code that is specific to the Informix-DB. I want to change the database, so all the code should be independent from a DB. Does anybody know texts or books concerning this problem?
thx
Marco SeumBasically there is syntax difference between both of them.
Lets say i want to join two table EMP and DEPT based on DEPTNO.
With Oracle SQL format its like this.
select e.*
from emp e, dept d
where e.deptno = d.deptnoHere the joining condition goes in the WHERE clause.
With ANSI SQL format its like this.
select e.*
from emp e
join dept d
on e.deptno = d.deptnoHere the join condition is mentioned separately and not in WHERE clause.
Oracle supports ANSI SQL starting from 9i version.
You can read more about the syntax difference Here -
What is Difference between ANSI SQL and ORACLE SQL
Hi,
I am going to take the assesment test for ANSI SQL Programming before that i want to know any difference between ANSI SQL and ORACLE SQL?
I am studying for SQL but the test will be ANSI SQL please let me give an idea about the both.

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.

OWB 10.2.0.4 ANSI SQL join problem
Hi
Its seams to me, that in OWB 10.2.0.4 there is something broken with ANSI SQL joins and instead of ANSI joins there is used oracle SQL joins only. Maybe someone can point some solutions? I can’t rewrite all mappings with union and other operators. And manually pl/sql editing also would be big problem."Am I correct in assuming you did not code ANSI joins?" -> yes, i am coding Oracle SQL joins and with this option just generating ANSI joins.
With ANSI SQL join you can use OR and IN operands (and code looks more readable).
It is question of performance (so for example 80% of dataset you can join by one column other 15% by second etc ..). So this all can be rewritten also in Split->join->union all, but if you have several such joins, this will be painfully. -
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 '(+)' -

Really appreciate the help!
Thanks.Hi,
Welcome to the forum!
To convert to ANSI syntax, replace join conditions in the WHERE clause
FROM x
, y
WHERE x.x1 = y.y1
AND x.x2 = y.y2with ON conditions in the FROM clause:
FROM x
JOIN y ON x.x1 = y.y1
AND x.x2 = y.y2In inner joins, conditions that do not reference 2 tables are not really join conditions, so it doesn't matter if they are in the FROM clause or in the WHERE clause.
In your case
SM.TRANSDEFID in (999,2329,2344,2370,150000903,150005362)could be part of a join condition involving sm, or it could be in the WHERE clause. Most people find it clearer if 1-table conditions like this are in the WHERE clause.
Again, this only applies to inner joins. For outer joins, all conditions that apply to a table that may lack matching rows must be included in the FROM clause, like this:
LEFT OUTER JOIN fvstock fvs ON sm.propref = fvs.recordid
AND fvs.fieldid = 2559
AND fvs.flevel = 'F'Try it.
If you have trouble, post your best attempt, along with CREATE TABLE and INSERT statements for a little sample data from all the tables involved, and the results you want from that data. Simplify the problem. Post only the tables and columns that you don't know how to handle.
See the forum FAQ {message:id=9360002}

AND SM.TRANSACTIONDATE BETWEEN {@STARTDATE@} AND {@ENDDATE@}This is not valid Oracle SQL. Is {@MATERIALID@} some kind of variable? -

If you are concerned about outer joins that can be performed using ANSI syntax that are not supported in the classic Oracle syntax then use in-line view and outer join the views.
If your code was properly formatted it would be possible for someone to read it and possibly see what you are seeing.
