Need help in writing inline query or subquery
Hi All,
I have 4 select statements like below ,
1>Select customer_number, customer_name,customer_address1
FROM ABC
WHERE Site_use_code='BILL_TO'
2>Select customer_number, customer_name,customer_address1
FROM ABC
WHERE Site_use_code='SHIP_TO'
3>Select customer_number, customer_name,customer_address1
FROM ABC
WHERE Site_use_code='SOLD_TO'
I need to write all these 3 in single select statement in such a way that if any select statement doesnot return any data it should execute the other select statements means it should not fail.
for each column of the select statment i can write separate select statements in that way it should work but the query should be very big.
So please help me on thsi.
Thanks

Need help with writing a query with dynamic FROM clause
Hi Folks,
I need help with an query that should generate the "FROM" clause dynamically.
My main query is as follows
select DT_SKEY, count(*)
from *???*
where DT_SKEY between 20110601 and 20110719
group by DT_SKEY
having count(*) = 0
order by 1; The "from" clause of the above query should be generated as below
select 'Schema_Name'||'.'||TABLE_NAME
from dba_tables
where OWNER = 'Schema_Name'Simply sticking the later query in the first query does not work.
Any pointers will be appreciated.
Thanks

Remember that anything inside quotes is case-sensitive. Is the owner really "Schema_Name" with a capital S and a capital N, and 8 lower-case letters?
Simply sticking the later query in the first query does not work.Right; the table name must be given when you compile the query. It's not an expression that you can generate in the query itself.
Any pointers will be appreciated.In SQL*Plus, you can do something like the query bleow.
Say you want to count the rows in scott.emp, but you're not certain that the name is emp; it could be emp_2011 or emp_august, or anything else that starts with e. (And the name could change every day, so you can't just look it up now and hard-code it in a query that you want to run in the future.)
Typically, how dynamic SQL works is that some code (such as a preliminary query) gets some of the information you need to write the query first, and you use that information in a SQL statement that is compiled and run after that. For example:
-- Preliminary Query:
COLUMN my_table_name_col NEW_VALUE my_table_name
SELECT table_name AS my_table_name_col
FROM all_tables
WHERE owner = 'SCOTT'
AND table_name LIKE 'E%';
-- Main Query:
SELECT COUNT (*) AS cnt
FROM scott.&my_table_name
;This assumes that the preliminary query will find exactly one row; that is, it assumes that SCOTT has exactly one table whose name starts with E. Could you have 0 tables in the schema, or more than 1? If so, what results would you want? Give a concrete example, preferably suing commonly available tables (like those in the SCOTT schema) so that the poepl who want to help you can re-create the problem and test their ideas.

Need help in writing SQL query
Hi,
I have a rquirement where I need to convert columns into records.
Table1:
(note: I have around 150 columns i.e period1 to period150)
unit startdate Period1 period2 period3 period4 period5
A 1/1/2011 100 200 300 400 500
Now I need data in below format
UNIT startdate period
A 1/1/2011 100
A 1/1/2011 200
A 1/1/2011 300
A 1/1/2011 500
Please suggest me...
Thanks.With UNPIVOT you can "name" each of your rows using as.
One trick is to "name" the rows to a number - then you can add that number of weeks to your start date - like this:
with t as (
select 'A' unit, DATE '2011-01-01' startdate, 100 period1, 200 period2 ,300 period3, 400 period4 ,500 period5 from dual
select
unit,
startdate + numtodsinterval(week*7,'day') startdate,
qty
from t
unpivot(
qty for week in (
period1 as 0,
period2 as 1,
period3 as 2,
period4 as 3,
period5 as 4
;Theoretically the above should work - but somehow I get a NULL date on my 11.1 instance? And I don't have another version to test with, alas.
But try it and see if it works on your instance ;-) -

Dear All,
My database is 11gR2 on Linux.
I am struck in writing a difficult query, need help from your guys.
I have a table, an application is controlling the columns of this table. Columns are added by the application.
This is the structure of the table:
create table imran_test(
2 username varchar2(100),
3 layer1 number(1),
4 layer2 number(2),
5 layer3 number(2));
-- where layer1, layer2, layer3.... are increased up to layer 22 and could be increased more...
Now each username will have 1 in any one of the layer, and all other layers will have 0
Like if I consider the above table this could be the sample data:
imran 1 0 0
hafeez 0 1 0
james 0 0 1
Now the result my query should return is:
select username, <column name where value is 1> and value of it, as per sample data, this should be return by the query:
imran layer1 1
hafeez layer2 1
james layer 3 1
Note: Please remember the columns are not fixed, they are added/altered by application.
Regards,
ImranThe table design is incorrect as it is not in 3NF and has a repeating group
You should correct the 'design' first or turn the layer... columns in a VARRAY.
Also my feeling is you should change your subject line 'Help in writing a query!' in 'Write my query' as that is what you actually ask, and leave out the exclamation mark.
Basically you dump everything in this forum, and being a bit less demanding might suit you better.
Also you still act rude by not marking your questions as answered.
Change that

Hi Friends,
I am trying to load Employees and their Assignments using APIs.
I have various columns in my staging table like Last Name, First Name, etc., but I need help in writing query in the cursor especially for columns Emp Number and Supervisor Number.
I have data as below
Emp_Number Supervisor_Number
GE0002 GE0064
GE0064 EG0009
EG0009 EG0001
100009 EG0001
EG0001 TU0001
Cursor I write will process the data in the same order as above, but here the problem is...
When it processes first row, it checks for supervisor GE0064 which do not exist and so it errors out.
Similarly for second row, it checks for supervisor EG0009 which again do not exist and so it errors out.
So in order to prevent this, the cursor should process the rows as below
Emp_Number Supervisor_Number
EG0001 TU0001
EG0009 EG0001
GE0064 EG0009
GE0002 GE0064
100009 EG0001
By this way, Supervisor should be defined first as an employee and then it can be used as a supervisor for other employees
is there a way that I can get the output as above(second set of data), when the table has records randomly as above(first set of data)
Appreciate your help!
Thanks,

Why did the number go up?
It's something only you can find out
Maybe some Emp have several Supervisor(s) like
with
t as
(select 'GE0002' Emp,'GE0064' Supervisor from dual union all
select 'GE0064','EG0009' from dual union all
select 'EG0009','EG0001' from dual union all

select 'EG0001','TU0001' from dual
select Emp,Supervisor,lpad('_',3 * (level - 1),'_')||Emp indent
from (select Emp,Supervisor

union all
select supervisor,null
from t tt

You haven't posted ANY 'java program' for us to help with.
The forum is NOT a coding service. It is to help you with YOUR code.
Post the code you have written and SHOW us (don't just tell us) how you compile it and execute it and the results you get. Then we can help you with any problems you are are having.
If you need help understanding just what the program should be doing you need to ask your instructor to clarify the assignment. -

Need help in writing a select query to pull required data from 3 tables.
Hi,
I have three tables EmpIDs,EmpRoles and LatestRoles. I need to write a select Query to get roles of all employees present in EmpIDs table by referring EmpRoles and LatestRoles.
The condition is first look into table EmpRoles and if it has more than one entry for a particular Employee ID than only need to get the Role from LatestRoles other wise consider
the role from EmpRoles .
Sample Script:
Create Table #EmpIDs
(EmplID int )
Create Table #EmpRoles
(EMPID int,Designation varchar(50))
Create Table #LatestRoles
EmpID int,
Designation varchar(50)
Insert into #EmpIDs values (1),(2),(3)
Insert into #EmpRoles values (1,'Role1'),(2,'Role1'),(2,'Role2'),(3,'Role1')
Insert into #LatestRoles values (2,'Role2')
Employee ID 2 is having two roles defined in EmpRoles so for EmpID 2 need to fetch Role from LatestRoles table and for
remaining ID's need to fetch from EmpRoles .
My Final Output of select query should be like below.
EmpID Role
1 Role1
2 Role2
3 Role1
Please help.

Hi,
Please help in writing a UDF for these fields in mapping, which I need for the object Iu2019m doing currently.
The fields are like this:
1) batch_no = "TRUNC((GetMaxObjid('x_txn_sap_parts')-POWER(2,28))/5000)+1",
2) lot_id = "TRUNC((GetMaxObjid('x_txn_sap_parts')-POWER(2,28))/500)+1",
3) How to use JDBC connection factory class in the UDF.
Some logic I can provide which I know i.e. Power (2, 28) means 2 to the power of 28 (2 multiplied 28 times), Trunc means truncate, X_TXN_SAP_Parts is a database table.The Target fields are Batch_no, lot_id & Objid.Actually, objid is mapped initially to a source field i.e. Object ID and in this function it is only being used for the calculation of the batch_no.
Thanks in Advance,

//field name of field required , as in database
catch (Exception e) {}
finally {
if (accessor != null)
accessor.close();
result.addValue((String)cValue);
--> I don't know what are the parameters to be used and how to be used in the UDF because this is the first time I'm writing a UDF.
--> The problem in using this query is that both OBJID & BatchNo. are on the target side and the value for the OBJID is retrieved by a SELECT query from the database.
Kindly help me how to resolve this query of mine.
Thanks in Advance.

Need help in building search query
Guys ..
Problem Description:
I have a huge table that is indexed using CONTEXT.
I want to write a search query that considers the following:
1. number of keywords match
2. takes care of spelling mistakes, synonyms and acronyms
3. proximity - the keywords should not be too far of each other.
e.g. I have this phrase: "Horizontal Stabilizer Trim Brake"
I was thinking of writing a query like:
SELECT SCORE(1) SCORE,
TEXT text
FROM MY_TABLE
WHERE CONTAINS(TEXT, '(Horz | Horizontal) ACCUM (Stab | Stabilier) ACCUM Trim ACCUM (Brk | Break)', 1) >= 0
ORDER BY SCORE DESC
The results doesnt look satisfactory. I have not used "near" operator as i dont know how to use it.
Please help me as I am very much new to Oracle Text.
-GWell, I'm not going to write the function for you, but we can at least talk through a general strategy.
A lot depends on how you help your users on the front end -- for example, if they're searching a technical document, you may want to return results that aren't perfect matches but you do want to make sure the user picks 'mandatory' and 'useful' keywords in a way that lets you figure out which ones are really important. On the other hand, if you're google and have to handle queries like 'horizontal stabilizer trim brake' and 'were Pete and Jenny in the break room' then you run the risk of spending too much time looking for interesting words, almost doing a full-text search on the query trying to derive meaning.
So I'm going to presume that you have some control over what/how the users generate their searches so that finding keywords isn't the issue.
The plan will be to parse the query a bit to find the interesting words, clean them up, and weigh their importance, then use transformed data to build the query template to score various combinations.
So here's some pseudocode for the function:
function parse_query(pQueryWords in clob) returns clob as
begin
generate_token_list (); -- split the query into a set of individual tokens/words
for each token in token_list
if it's a mandatory word then accumtokenlist := accumtokenlist || ' ' || token ||'*10' -- weigh the presence of the token strongly
if it's a useful word then accumtokenlist := accumtokenlist || ' ' || token ||'*5' -- domain-specific words are also important
if it's a stopword or reserved word, then do not add it to the list
if it's not on my lists, then accumtokenlist := accumtokenlist || ' ' || token
and normaltokenlist := normaltokenlist ||' ' || token
end;
--so now, we have two lists, one for NEAR and one for ACCUM
now build the guts of the template
querytemplate := querytemplate || '<seq> || normaltokenlist || '</seq>';
querytemplate := querytemplate || '<seq> || replace (accumtokenlist, ' ',' ACCUM ') || '</seq>';
querytemplate := querytemplate || '<seq>$' || replace(normaltokenlist,' ','$') || '</seq>';
querytemplate := querytemplate || '<seq>? || replace(replace(accumtokenlist,' ',' ?'),' ', ' accum ') || </seq>'; -- first fuzzy the words, then accum
querytemplate := querytemplate || '<seq>? || replace(replace(normaltokenlist,' ',' ?'),' ', ' near ') || </seq>'; -- first fuzzy the words, then near
return querytemplate
end;So, with a 'cooked' query text that is template-friendly, all we need to do is apply a template that is aware of your inputs:
query_Template_string := '
