How to simplify this query in sql simple select stmt
HelloPlease simplify the query
I want to convert this query in a single select statement. Is this possible?
If uarserq_choice_ind is not null then
Select ubbwbst_cust_code
From ubbwbst,utrchoi
Where utrchoi_prop_code=ubbwbst_cancel_prod
Else
Select max(utvsrvc_ranking)
From utvsrvc,ubbwbst
Where utvsrvc_code=ubbwbst_cancel_prod
End if
Select ubbwbst_cust_code as val
From ubbwbst,utrchoi
Where utrchoi_prop_code=ubbwbst_cancel_prod
AND uarserq_choice_ind is not null
union all
Select max(utvsrvc_ranking) as val
From utvsrvc,ubbwbst
Where utvsrvc_code=ubbwbst_cancel_prod
and uarserq_choice_ind is null
Without more information, we are unable to combine the two queries in 1 without a union.
Looks like you select values totally disperate of totally different tables

Can anyone simplify this query
Here's a DOF from two tables
1. CREATE TABLE (EMPL)

ENAME VARCHAR2 (25).
USE VARCHAR2 (25).
KEY ELEMENTARY SCHOOL (SNO)
);
2. CREATE TABLE EMPL_DET)
NUMBER OF SNO
SAL VARCHAR2 (25)
);
Here are tables LMD
INSERT INTO EMPL (SNO, ENAME, JOB) VALUES (1, 'SMITH', 'CLERK');
INSERT INTO EMPL (SNO, ENAME, JOB) VALUES (2, 'SMITH', 'MANAGER');
INSERT INTO EMPL (SNO, ENAME, JOB) VALUES (3, 'TOM', 'CLK');

INSERT INTO EMPL_DET (SNO, SAL) VALUES (2, "10000");
INSERT INTO EMPL_DET (SNO, SAL) VALUES (3, '900');
I want to calculate TotalSAL (column: empl_det.) SAL) of each employee (empl.ename) with job-description (empl.job).
Means I want following the lines of output
1.(Job,TotalSAL,Ename)-> (CLERK, 11000, SMITH)
2->.(Job,TotalSAL,Ename) (MANAGER, 11000, SMITH)
3->.(Job,TotalSAL,Ename) (CLK, 900, TOM)
I tried to write down to unique ename
Select JOB, x.sal, ename in empl,
(
Select sum (sal) sal empl_det where sno in
(select sno to empl where ename = 'SMITH')
) x
where ename = 'SMITH '.
order by ename
each ename, I draw from this query. How can I make the ename list (TOM SMITH) to this request?
Or can anyone simplify this query?Hello
in this case, you need to use is analytical functions:
that is to say:
SELECT e.job, SUM (d.sal) OVER (PARTITION BY e.ename) AS "TotalSal" , e.ename FROM empl e, empl_det d WHERE d.sno = e.sno AND e.ename IN ('SMITH', 'TOM') ORDER BY e.ename; JOB TotalSal ENAME ------------------------- ---------- ------------------------- CLERK 11000 SMITH MANAGER 11000 SMITH CLK 900 TOMKind regards.

How to write this query in the hierarchy
Hi gurus,
Really need your help on this query. Thank you very much in advance.
SELECT t1.key as root_key , (SELECT t2.unit_id AS unit_id level-1 AS level , t2.name, t2.creator FROM tab t2 START WITH t2.unit_id = t1.unit_id -----check each node as root CONNECT BY prior t2.unit_id = t2.parent_unit_id ) t1.name as parent_unit_name FROM tab t1
I'll write a query of the hierarchy as above, and that EACH line (node, totally more than 10200) is checked as root node to see how many sheets are accessible for her... It must be implemented in a single query.
I know inline query should NOT return multiple rows or multiple columns, but the inline elements are necessary and can certainly be made in a correct solution.

Explain the plan:
Table1 a record 3Million and table 2 has 1 million records.
I used gather stats before you run this query and 'Full' trick, even in this case, he is running for 45 minutes.
Please suggest the best solution to optimize this query.
Thanks in advance.
Remove the tips.
No need for the separate.
Get the diff by ceil (abs(t2.m_date-t1.m_date)) and the filter for that where value_diff<>
Assing the statement ".. MATCHED" lately in the update clause.
Maybe give exactly to your needs with a small example may be the query may be getting more simplified or not what you want it to do.

Hi people,
I need to get a query in which a set of records, I get ONLY those which previous registry has a field with a value to this topic. Other values, the field can contain are not necessary.
I know that sounds easy but... I can't get it.
So, for Oracle 10 g 2... Here's my query:
SELECT a.person_id, a.person_status, a.message_id, a.order_id
OF t_HR one
WHERE a.person_status = "rejected".
AND a.id >
(SELECT max (b.id)
OF t_HR b
WHERE b.person_id = a.person_id
and b.order_id = a.order_id
AND b.person_status! "revised =".
B.ID AND < a.id)
ORDER BY desc a.id
Let me explain:
1 - HR table is a table of people. These people has serveral STATUS.
2 - ID is a sequential (each www.voyages-sncf.com has a different identification number).
3 - the application must get THAT all people "rejected".
4. - However, (subquery) I need ONLY those that previous register (the second register) holds a status of "OK". If the person holds a "revised" status he's not, he should be the next register (the third)
5.-L' ORDER ID DESC, so is the first register must have a STATUS = "rejected" and the second a 'OK '. IF the second register = "revised", then the third register must be 'OK '. And I need this query.
HOW DO?
My problem: the subquery gives you previous register of the same guy, but... it does not give you the value of the State, I need, which is 'OK '.
I tried to add to the subquery...
SELECT max (b.id)
OF mod_human_resource b
WHERE b.person_id = a.person_id
and b.order_id = a.order_id
AND b.person_status = 'OK '.
AND b.id < a.id
... but if I have 5 records of that person, the first is "rejected", the second is "accepted", the third is 'new' and the fourth is 'OK'... the subquery gives you the 4th register and which is not correct for me, it must be only the second one (prior to the first State registry).
I need to be a query, because I need to use it on a MERGER for a DWH.
If there is another way (function, or even a procedure) to make the MERGER rather than with a request, which would be ok too. I am poor DWH knowledge.
Thanks in advance.
Hello
So, you need to know if a line is the 'first' line, and you should also know what is the 'next' status, (even the 'first' and 'next' are already defined). This sounds like a job for analytical functions. ROW_NUMBER can tell you if a line is first or not, and LEAD can tell you what a value on the next row.
Since you post CREATE TABLE and INSERT statements for your own table, I'll use the table scott.emp to illustrate.
Consider these data from scott.emp:
SELECT DeptNo
ename
work
FROM scott.emp
ORDER BY deptno
ename DESC
;
Output:
DEPTNO ENAME JOB
---------- ---------- ---------
10 MILLER CLERK
PRESIDENT OF KING 10
MANAGER 10 CLARK
20 SMITH CLERK
ANALYST SCOTT 20
20 JONES MANAGER
20 FORD ANALYST
20 ADAMS CLERK
30 WARD SALESMAN
SELLER OF 30 TURNER
30 MARTIN SALESMAN
30 JAMES CLERK
MANAGER BLAKE 30
30 ALLEN SALESMAN
Now, let's say we want only who know the departments where the forefront (in order descending ename) a job = 'CLERK', and the following line (also in descending by ename order) = "ANALYST" job, and we want to know the ename of the first row. In other words, the correct output is:
DEPTNO ENAME
---------- ----------
20 SMITH
Note that deptno = 10 is not included, even if the first task is to "CLERK." that was because the second job in deptno = 10 is the "PRESIDENT", not "ANALYST."
Here's a way to get these results:
WITH got_analytics AS
(
SELECT ename, deptno, job
ROW_NUMBER () OVER (PARTITION BY deptno
ORDER BY ename DESC
) AS r_num
LEAD (employment) OVER (PARTITION BY deptno
ORDER BY ename DESC
) AS next_job
FROM scott.emp
)
SELECT deptno, ename
OF got_analytics
WHERE r_num = 1
AND job = 'CLERK '.
AND next_job = 'ANALYST '.
;
I hope that answers your question.
If this isn't the case, then, as Dan (and the FAQ forum) said, post CREATE TABLE and INSERT statements for some sample data and the exact results you want from these data.
Post your query, based on the one I have posted more top and ponit out where he gets results.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

It works perfectly fine. Now, I want to turn this query in custom procedure. I write the following code to create the SQL procedure,

end;
end;
but it is not compiling. Someone knows what's the problem?
With respect,
Sunil BhatiaHi Sunil,
You cannot use the function v ('P32_BODY') to assign values.
you will need to use:
apex_util.set_session_state ('P32_BODY', l_vc_arr2 (3));Concerning

How to solve this query in database using sqlite phone gap
am facing a problem in recent days. The problem is database. In fact, I create the mane database 'casepad '. Then I created a table because the database 'table of cases' have (ID, name, date). Now I insert the value on this table. When inserting I also create a name ("casename") .mean table if I insert the value of the case table (1, 'AB', 2/13). Then I create table AB. Now I need to get the value of the case table (I am) but I need to count the number of items in another table (AB). Here, I had to try it.
function onDeviceReady() { db = window.openDatabase("Casepad", "1.0", "Casepad", 200000); db.transaction(getallTableData, errorCB); } function insertData() { db.transaction(createTable, errorCB, afterSuccessTableCreation); } //createtableandinsertsome record function createTable(tx) { tx.executeSql('CREATE TABLE IF NOT EXISTS CaseTable (id INTEGER PRIMARY KEY AUTOINCREMENT, CaseName TEXT unique NOT NULL ,CaseDate INTEGER ,TextArea TEXT NOT NULL)'); tx.executeSql('INSERT OR IGNORE INTO CaseTable(CaseName,CaseDate,TextArea) VALUES ("' + $('.caseName_h').val() + '", "' + $('.caseDate_h').val() + '","' + $('.caseTextArea_h').val() + '")'); } //function will be called when an error occurred function errorCB(err) { navigator.notification.alert("Error processing SQL: " + err.code); } //function will be called when process succeed function afterSuccessTableCreation() { console.log("success!"); db.transaction(getallTableData, errorCB); } //select all from SoccerPlayer function getallTableData(tx) { tx.executeSql('SELECT * FROM CaseTable', [], querySuccess, errorCB); } function querySuccess(tx, result) { var len = result.rows.length; var t; $('#folderData').empty(); for (var i = 0; i < len; i++) { $('#folderData').append( ' - ' + '' + '

[8i] not to simplify this query?
In my application, I need to pick up three possible prices for each part number in an array.
The three possible prices that I need to recover are:
(1) the price paid on the order more recently closed,
(2) the price mentioned on the first pending order, and
(3) the price on the furthest on pending order.
However, there is a complication in that. Orders include the part number, but may also include a prefix of 4 characters (always the same) on a reference number which should be treated the same as the reference database. For example, "DSB-part1" should be considered "part1", "DSB-part2" should be regarded as 'part 2', etc.
In addition, it is quite possible for several orders expected or closed on the same day, and I want to only return the price of one of these lines for each of the 3 methods of pricing.
(Technically, there is another level of complication to this, but if I have problems with it later, I'll create a new job for him...)

It is a little bit shorter than what you have posted, probably more effective and (in my opinion) much easier to debug and maintain:

Is there a reason to have raw triling part_no or ord_part_no?

After this announcement, I saw that Max had posted essentially the same query.
In general, where the solution of Max seems more simple, I like her way better.
The only possible exception is tested for "OP" at the derivation of the values first_open and last_open. If none of the lines to an ord_stat part_no = "OP", solution of Max will be used a the lines with another ord_stat. That does not occur in the sample data, and I don't know if this is still possible in your application, but if this is the case, I don't know this isn't what you want. -
How do to this chain operation looks simple but causing a lot of time to do :)
Hi all
I have a very large chain, i.e. the soap xml response send by server that I read once connected to the server using http, now the problem is that I need to create a Document out of it and analyze what is simple but the answer I get server requires many replacements of string as example 1) replacing "<" with "<" 2)="" replacing="" ">"="" with="" "="">" etc before creating a document out of it now there are many such replacements in the sending of the response from server that takes a lot of time. 5 minutes on the emulator. So my question is how do? Is there a native method to replaceAll occurrences of a substring in a string or while I can use or is there another good way? Please let me know thx.
Thank you
Sagar
We took over a project done by someone else, and they were doing exactly what you do. Here is their source, which I think is more effective that you give it a try if you want.
But be aware that I have never used or tested this code.
I guess you pull that string to the center of your SOAP response. It has been encoded XML. So you can do what we did in this case and wrap the string as a data element in an XML element and then use the XML parser to get the actual data, which feed us an XML parser again to get the actual data. XML is already set up to deal with these characters, so it was more effective than the approach to replace. Actually to be honest, it wasn't the reason we exchanged, that as part of the parser XML meant we were convinced it was done correctly.
public String replaceAll(String source, String pattern, String replace) { if ((source != null) && (pattern.length() > 0)) { final int len = pattern.length(); StringBuffer sb = new StringBuffer(); int found = -1; int start = 0; while ((found = source.indexOf(pattern, start)) != -1) { sb.append(source.substring(start, found)); sb.append(replace); start = found + len; } sb.append(source.substring(start)); return sb.toString(); } else return ""; } -
How to optimize this query XMLDB

Create an index as above, but it does not seem to be used to explain the plan for the part of XML query.
and a lot of time, I also get this error but I cannot now re - produce for some reason.
I thought that its because I can't index after branch out according to s_ID

Why can't I see the index above in the plan to explain it?

Is it possible to tell Oracle to a join index or some kind of faster join after the XML select part.
My real case got way as many lines to make the join of X - Y and it may be nice to have an index to quickly reach?
When do some small tests, the clause will eventually cause oracle core dump. It should not happen even it is a virtual machine with 3G of memory max and the max_memory_target = 800 M as all my data are not not even 50 M.
We are the team of analysts and Dev team suggest that is a little too much time to contact Oracle Support and I finally create 3 global temporary table with commit preserve rows and operate with performance much better.
Instend of show the value of 'i' in the view list, I need to show how many element in the table. I have to call synchronize because I call a query that counts the number of elements to 'result.rows.item (i). CaseName"this item... ?
