Sub queries in CR 11

Post Author: pranathi20
CA Forum: Data Connectivity and SQL
Hi All,
Can someone help me with the below SQL query? I am not sure how to have the sub query in CR
SELECT x.created_on, x.ssn, x.age , max(DECODE(x.rn,1,x.nlsi_answer)) BIO001 , max(DECODE(x.rn,4,x.nlsi_answer)) BIO116 , x.nlsipvsc
FROM (SELECT nlsiview.created_on created_on , nlsiview.ssn ssn , nlsiview.age age , nlsiview.answer nlsi_answer , ROW_NUMBER() OVER (PARTITION BY nlsiview.created_on, nlsiview.ssn ORDER BY NULL) rn FROM nlsiview ) x GROUP BY x.created_on, x.ssn, x.age ORDER BY x.created_on, x.ssn /

I Assume that you have done creating required OCE, and familiar with the single table query process. You can create sub queries using the Custom SQL feature, which is located under view menu->custom SQL. Please note that the query data model must have at least one table to use this feature.
Here are the steps to create sub query.
1. select the main table from table catalog list
2. select the required columns from table and right click " add selected items" to request section.
3. go to View menu - > custom SQL
4. you will see a section which is editable enter all your where clause and sub query section and then process.
Let me know if you need any detail information.

IN clause with ORDER BY clause in sub-queries

Hello,
We generate dynamic queries with the following statement pattern (could be many union/intersect sub-queries):
select my_col
from my_table
where my_col IN
select table_2.my_col , x_col from table_2 where x_col > 10
UNION
select table_3.my_col , y_col from table_3 where y_col > 20
INTERSECT
select table_4.my_col , z_col from table_4 where z_col is between 30 and 50
I know that I can do just the sub-queries w/ an ORDER BY clause as follows (as long as the 2nd parameter in the select stmts are of the same type):
select table_2.my_col , x_col from table_2 where x_col > 10
UNION
select table_3.my_col , y_col from table_3 where y_col > 20
INTERSECT
select table_4.my_col , z_col from table_4 where z_col is between 30 and 50
order by 2 desc
But my questions are:
1. What is (if there is) the syntax that will ensure that the result set order will be that of the ordering of the sub-queries?
Or does my SQL stmt have to have syntactically (but not semantically) change to achieve this?
Thanks,
Jim

just a minor doubt - I think it is not officially supported to have separate ORDER BYs in a compound query with set operators (e.g. UNION / UNION ALL subsets). Of course one could use inline views with NO_MERGE + NO_ELIMINATE_OBY hints, but I think the only officially supported approach is to use a single, final ORDER BY (that needs to use positional notation as far as I remember).
Randolf,
You're right, of course, about the separate "order by" clauses.
Interestingly the following type of thing does work though (in 10.2.0.3, at least):
with v1 as (
    select * from t1 where col1 = 'ABC' order by col2
v2 as (
    select * from t1 where col1 = 'DEF' order by col2
select * from v1
union all
select * from v2
;A quick check the execution plan suggsts that Oracle appears to be convering this to the following - even though its technically not acceptable in normal circumstances:
select * from t1 where col1 = 'ABC' order by col2
union all
select * from t1 where col1 = 'DEF' order by col2

With clause vs sub-queries

db and dev 10g rel2 , hi all,
i am trying to learn the "WITH CLAUSE" , and i do not see any difference between using it and using sub-queries .
when i searched for this , i found that the with clause is used when You need to reference the subquery block multiple places in the query by specifying the query name , but i can not imagine an example for doing so .
if you could provide me with an example please ? and telling me about another situations in which i could need using the "with clause" if any ?
thanks

It isn't just about referencing a subquery multiple times. There are other advantages to using 'common table expressions'/'subquery factoring' also.
Take a look at the example below. It first defines 'dept_costs' as a query block, then defines 'avg_cost' as a new query block and it references the first query block.
Then the actual query references both query blocks just as if they are tables. And, in fact, in some circumstances Oracle will actually materialize them AS temporary tables.
Look at how easy it is to understand the entire statement. You can focus first on the 'dept_costs' query block WITHOUT having to look at anything else. That is because the query block is self-contained; you are defining a result set. There is no 'join' or connection to any other part of the statement.
It is easy for a developer, and for Oracle, to understand what is needed for that one piece.
Next you can focus entirely on the 'avg_cost' query block. Since it uses the first query block just as if it were a table you can treat it as a table. That means you do NOT even need to look at the first query block to understand what the second query block is doing.
Same with the actual query. You can analyze it by treating the two query blocks just as if they were other tables.
Even better you can test the first query block by itself in sql*plus or other tool to confirm that it works and you can create an execution plan for it to make sure it will use an appropriate index. You can also then test the first and second query blocks together to make sure THEY have a proper execution plan.
Then when you test then entire statement you already know that the query blocks work correctly.
Try to do THAT with a query that uses nested sub-queries.
Sure - you could write a set of nested sub-queries to accomplish the same thing (Oracle will sometimes rewrite your query that way itself) but it becomes one big query and the individual pieces are not nearly as easy to see, analyze or understand.
It can be difficult if not impossible to extract a nested query in order to test it even to just try to get the syntax working. And when you do extract it you will often be testing something that isn't quite exactly the same as when i t was nested.
So: easier to understand, easier to write and test (especially for new developers) as well as easier to use multiple times without having to duplicate it.
>
subquery_factoring_clause
The WITH query_name clause lets you assign a name to a subquery block. You can then reference the subquery block multiple places in the query by specifying the query name. Oracle Database optimizes the query by treating the query name as either an inline view or as a temporary table.

Subquery Factoring: Example The following statement creates the query names dept_costs and avg_cost for the initial query block containing a join, and then uses the query names in the body of the main query.

FROM employees e, departments d
WHERE e.department_id = d.department_id

Sub Queries VS Variables in the Query

#1
for i in ( select a.name,b.price,a.date from
list a, sales b
where a.header_id=b.header_id
and b.date_key= (select date_key from date_tab
where date_field=trunc(sydate))
loop
end loop.
#2
select date_key into v_date_key from date_tab where date_field=trunc(sydate);
for i in ( select a.name,b.price,a.date from
list a, sales b
where a.header_id=b.header_id
and b.date_key= v_date_key)
loop
end loop.
Please advice me , using the sub queries(#1) or substution variable (#2) in the condition part will improve the performance of the query.
Thanks

Most likely, there won't be a difference in performance.

Sub queries

i have a longish query which runs correctly in Oracle 8i Lite thro SQL Plus but does not run when using JDBC.
The query has multiple subqueries and it looks like
delete from node_initial_values d where d.node_id in (select c.node_id from node_master c where c.node_id=d.node_id and c.node_id in (select e.node_id from network_design e where c.node_id=e.node_id and e.network_id in (select b.network_id from network_master b where e.network_id=b.network_id and b.network_id in (select g.network_id from output_network_scenario g where g.network_id=b.network_id and g.output_network_master_id in (select a.output_network_master_id from output_network_master a where a.output_name= 'network three')))));
assume all the tables exist with correct data. the above query works perfectly well in SQL*plus but when i use
the following code i get an error
PreparedStatement deleteNodeInitialValuesPst=getConn.prepareStatement("delete from node_initial_values d where .... a where a.output_name= ?)))))");
deleteNodeInitialValuesPst.setString(1,"network three");
deleteNodeInitialValuesPst.executeUpdate();
getConn.commit();
... rest of the code
the error code oracle 8i lite gives is
java.sql.SQLException: [POL-4200] bad action for transaction operation
would really appreciate any help in this regard...
specifically can anyone tell me if prepared statement is the correct function to use here...
thanks

I made the following changes:
changes to the code, new code mentioned below
changed the database to oracle 8i enterprise edition running on NT.
new code now is
// connetion parameter and other code here
String deleteNodeInitialValuesStr=
"delete from node_initial_values d where d.node_id in (select c.node_id from node_master c where c.node_id=d.node_id and c.node_id in (select e.node_id from network_design e where c.node_id=e.node_id and e.network_id in (select b.network_id from network_master b where e.network_id=b.network_id and b.network_id in (select g.network_id from output_network_scenario g where g.network_id=b.network_id and g.output_network_master_id in (select a.output_network_master_id from output_network_master a where a.output_name='"+nextElementStr+"')))))";
Statement deleteNodeInitialValuesSt=getConn.createStatement();
deleteNodeInitialValuesSt.executeQuery(deleteNodeInitialValuesStr);
getConn.commit();
} // end try
catch(SQLException ex) {
while(ex !=null){
out.println("Java SQL Exception: " + ex.getMessage()+"<br>");
out.println("Vendor error code: " + ex.getErrorCode()+ "<br>");
out.println("SQL State: " + ex.getSQLState() + "<br>");
ex=ex.getNextException();
} // end while
} // end catch
// more code here
the output i get is
Java SQL Exception: 202
Vendor error code: 0
SQL State: null
I turned off getConn.commit(), but the error code remains the same. is there an alternative to the sub queries above. where can i get the meaning of the error codes thrown by the exception ?
thanks

How can I create "Sub Queries" in a select statement?

Hi all,
I need to create reports, which are not based on a single table but on several "sub-queries".
This would be the code, but I don't know how to solve that problem...
SELECT OGBI.*
FROM
(((select "OSSRALL"."FORECAST_OWNER", sum
("OSSRALL"."TOTAL_OPPORTUNITY_AMOUNT")
from "#OWNER#"."OSSRALL" "OSSRALL",
"#OWNER#"."TEAM_MAIN" "TEAM_MAIN",
"#OWNER#"."MA_MAIN" "MA_MAIN"
group by "OSSRALL"."FORECAST_OWNER")OGBI.APPSME1)
where "OSSRALL"."OPP_CLASS" = (EX_OTHERS)),
-- more are following
"#OWNER#"."OSSRALL" "OSSRALL",
"#OWNER#"."TEAM_MAIN" "TEAM_MAIN",
"#OWNER#"."MA_MAIN" "MA_MAIN"
WHERE
("MA_MAIN"."MA_NAME"||', '||"MA_MAIN"."MA_FIRST_NAME"||' Mr'
like "OSSRALL"."FORECAST_OWNER" or
"MA_MAIN"."MA_NAME"||', '||"MA_MAIN"."MA_FIRST_NAME"||' Mrs'
like "OSSRALL"."FORECAST_OWNER" or
"MA_MAIN"."MA_NAME"||', '||"MA_MAIN"."MA_FIRST_NAME"
like "OSSRALL"."FORECAST_OWNER") and
("OSSRALL"."SALES_GROUP"="TEAM_MAIN"."NAME") and
("MA_MAIN"."MA_ID"=:P17_VB1)
thx a lot for your help.
kind regards Jan

Please can you post the full select statement and the DDL to create the tables? Or, provide someone access to the app on the Oracle server.
We can probably make these much more readable using table aliases and removing the owner unless you are doing this across schemas or via a wizard?
It looks like you are missing joins in your query - is this what you mean by subqueries? It is a good idea to move the join up before the WHERE clause if you can as this makes the query easier to manage.

Using Sub Queries in OBIEE

Hi,
I am new to the OBIEE world and was wondering how we can work with sub queries. I have the following problem.
I have a table namely XYZ in which we have "effective date" and "Amount". In the answers section have have filter out the data for the month of 01-Nov-08 to 30-Nov-08 which shows the total cash amount for that month. Now the problem is that I need to use the same "effective date" and "Amount" to get the opening balance which is calculated by Sum(Amount) where "effective date" < 01-Nov-2008. If i try to do this I do not see any results as the data gets filtered out. Can someone please help me on this?
Thanks

Hi,
In column formula put column level filter like this FILTER("Facts Revenue".Revenue USING (Time."Day Date" < date '2006-10-09'))

Can anyone tell me WHY Oracle won't allow sub-queries in outer joins?

Hi,
I've recently been tasked with converting a series of InterBase dbs to Oracle.
Many of the queries in the InterBase dbs use sub-queries in outer joins. Oracle won't countenance this (01799 - a column may not be outer-joined to a subquery).
I can get around it using functions but WHY won't Oracle allow this?
SQL Server allows it, InterBase allows it (I don't know about ANSI SQL) but it seems to be a common enough technique...
I'm just curious (and also a little frustrated!).
Thanks in advance,,,

Hi,
>>Oracle treat an empty string as a NULL
Well, you same answer your question. Because it is empty
SGMS@ORACLE10> create table tab (cod number, name varchar2(1));
Table created.
SGMS@ORACLE10> insert into tab values (1,'');
1 row created.
SGMS@ORACLE10> insert into tab values (2,' ');
1 row created.
SGMS@ORACLE10> commit;
SGMS@ORACLE10> select cod,dump(name) from tab;
       COD DUMP(NAME)
         1 NULL
         2 Typ=1 Len=1: 32
SGMS@ORACLE10> select * from tab where name is null;
       COD NAME
         1Cheers
If you talking about language tools, for example PHP treat empty string <> of NULL values. e.g: functions like is_empty() and is_null()

[8i] Question on hints when there are sub-queries / in-line views

I've noticed that when I query my database, it seems to default to the RBO rather than the CBO. I've been troubleshooting a huge query that takes a good half an hour to run... First, when I saw it was using the RBO, I added the /*+ CHOOSE */ hint (to my top-level SELECT), but that didn't help much. So, I decided to go through all the sub-queries / in-line views. One of my sub-queries, with no hint, takes 2.5 min. to run. I added the /*+ CHOOSE */ hint to it, and it only took 20 seconds.
My question is, if I add a hint to the top-level SELECT, does it get applied to every sub-query, or do I need to put that hint in every sub-query as well?

I just tested this out... I ran a portion of my query with a couple of sub-queries, and the first time, I just put the CHOOSE hint in my top level SELECT statement. The second time, I put it in both the top level and in the SELECT statement of one of the sub-queries. The explain plans are too long to post, but these are the statistics:
1st run (only 1 hint):
Statistics
          0 recursive calls
       2345 db block gets
     885019 consistent gets
        681 physical reads
          0 redo size
     185226 bytes sent via SQL*Net to client
      11371 bytes received via SQL*Net from client
        160 SQL*Net roundtrips to/from client
          0 sorts (memory)
          1 sorts (disk)
       2371 rows processed
timing for: query_timer
Elapsed: 00:00:29.092nd run: (2 hints)
Statistics
         14 recursive calls
       2345 db block gets
     885035 consistent gets
        620 physical reads
          0 redo size
     185226 bytes sent via SQL*Net to client
      11371 bytes received via SQL*Net from client

       4498 sorts (memory)
          1 sorts (disk)
       2371 rows processed
timing for: query_timer
Elapsed: 00:00:56.03It looks to me like the first one ran more efficiently. Can someone explain this to me? I figured that putting hints in the sub-queries would, at worst, do nothing, and at best, improve the performance, but it looks like the opposite happened.

Disco Plus and Sub-queries in conditions

Hi,
I have a strange behaviour for a report using a sub-query in the condition:
in Desktop Edition and Viewer it works just fine, in Plus no data is returned.
I am using Discoverer 9.0.2.
The condition was created from the Desktop using an existing datasheet, both data sheets using the same parameter.
I examined the SQL code from Plus and the statement returns data and the sheet with the sub-query also returns data - nevertheless the report doesn't return any data.
As far as I know you cannot create or modify sub-queries in conditions with PLus - but at least the report should work?! Does anyone know where the problem could be?
Thank you very much in advance!
Alex

Trying to create a sub-query in discoverer...
Using Desktop (9.04 and 10.1.2), the option "Create Sub-Query" is not available in the condition values. Feel like I'm missing something - has anyone come across this before?
I assume sub-queries should be possible/supported in Plus 10.1.2 (although it's not in the user guide). If so, the Create Sub-Query option is not available like in Desktop. If not, why not - seeing as it's basic sql commonly used in reporting?
Thanks!

Usage of joins & sub-queries

can anyone help me know the situation when to use the joins and sub-queries manipulating with more than one tables???? which among the two is faster normally???? because we can do same process using both these options.....

Balasubramaniam:
I think I can be so bold to say that, in general, joins are faster than sub-queries. But there are a lot of variables - data types, row/table sizes, indexes.
Try it and compare, with your production data.

A Single query with out the sub-queries

I am using My-SQL as my back-end and it doesnot support the
Sub-Queries. i have my table given below
UserID..UserName..ParentUserID
1........Admin...........0
2........Sales...........1
3........Sourcing........1
4........SalesHead.......2
5........SourcingHead....3
6........SalesExec.......4
7........SourExec........5
The table contains heirarchy of users. The top most users
has the ParentUserID as 0. and the remaining has their own ParentUserID
I want to get the complete heirarchy of a given user in single ResultSet.
It should be done without using sub-queries. but all joins can be used.
e.g.
if i say userid is 2 i should get following output:
Sales - > SalesHead -> SalesExec->......
Can any body please help me out!
Sridhar.

Hi Sridhar,
You can use recursive method. Make a method as follows :
public String getChildren(int UserID)
     String temp = "";
     Connection con = DriverManager.getConnection("","","");
     Statement st = con.createStatement();
     ResultSet rs = statement.executeQuery("select UserID from MyUsers where ParentUserID = " + UserID);
     while(rs.next())
          temp += " [ ";
          if(temp.equals(""))
               temp += getChildren(rs(0));
          else
               temp += " -> " + getChildren(rs(0));
          temp += " ] ";
     return temp;
then call his method by providing any UserID to it and it will return you a string containing complete hierarchy in the following format :
AAA -> BBB -> CCC -> DDD
I hope it will help you.

Humayun

Can you pass parameters with sub queries

I have created a Custom folder within a Business Area using a sql query that has multi sub queries. I need to be able to pass date parameters at the top level and at each sub query levels. Is this possible, or how can it be done in Discoverer?

Ok,
I just tried that and it still doesn't pass anything to the prompt.
I changed the prompt to an edit field and I made the following weblink but when i click the link from an account it doesn't put anything in the prompt and all data for all accounts is shown.
This is the URL maybe I messed something up...

For simplyfying things, let's assume that I have two tables
MAIN and USERS
USERS contains the fileds ID, FIRSTNAME, LASTNAME
MAIN contains AUTHOR, EDITEDBY, APPROVEDBY
My question is, how do I retrieve the three instances of
FIRSTNAME and LASTNAME?
I assume I need to use sub-queries, but have never
successfully used them before...

Hi Dan,
What I am trying to do is return the first name and last name
of three separate people.
How do I return multilple values of FIRSTNAME / LASTNAME?
One that corresponds to MAIN.AUTHOR and MAIN.EDITEDBY and
MAIN.APPROVEDBY?
Eg. MAIN.AUTHOR = '1', MAIN.EDITEDBY = '2' etc.
USERS table contains ID, FIRSTNAME, LASTNAME
1, fred, nurk
2, john, smith
I need a result set that allows john smith and fred nurk to
appear on the same row.
I was originally thinking of using a subquery... but perhaps
I need to use Tables aliases? i really don't know - thus my asking
