Need help in framing an SQL query - Sample data and output required is mentioned.

Sample data :
ID Region State
1 a A1
2 b A1
3 c B1
4 d B1
Result should be :
State Region1 Region2
A1 a b
B1 c d

create table #t (id int, region char(1),state char(2))
insert into #t values (1,'a','a1'),(2,'b','a1'),(3,'c','b1'),(4,'d','b1')
select state,
max(case when region in ('a','c') then region end) region1,
max(case when region in ('b','d') then region end) region2
from #t
group by state

Need help in framing an SQL query

Hi ,
Requirement is that
Let’s say I have a table say X
I am passing two input params from UI and in DAO i am querying these input prams against the table X(has c1,c2 as columns ) (as it has two columns mapping the input params A,B from UI).
if either one or Both of the input params matches ,only then i should fetch the records accordingly. It's understood that there won't be a scenario that both input params are null from UI.
I have three conditions here,
1.     A match against X, B doesnt Match
2.     B match against X, A doesnt Match
3.     Both A & B match against X
if i use let's say,
SELECT *FROM X WHERE (c1= A OR c2= B) .
•     if A match against X B doesnt Match It is fetching all the records matching A - requirement fullfilled
•     B match against X A doesnt Match It is fetching all the records matching B- requirement fullfilled.
•     Both A & B match against X It is fetching all the records from the table matching the first condition (which here is A) . requirement not fullfilled.
I am thinking of using the following query but I need to frame it in a way that based on ACHK & BCHK we need to add the conditions.
SELECT CASE WHEN C1 = A THEN 0 ELSE 9 END AS ACHK, CASE WHEN C2 = B THEN 0 ELSE 9 END AS BCHK FROM X
Based on ACHK & BCHK append the conditions. i.e.
IF ACHK = 0 AND BCHK = 0 THEN
AND C1 = A AND C2 = B
ELSE
AND (C1 = A OR C2 = B)
Please help.

Would be glad if you can shed some light on role of DENSE_RANK here (ofcourse i did read the forums but i am confused on what basis a row is ranked).Complicated queries and expressions are usually built of smaller, simpler parts. To understand how the big, complicated thing works, look first at the smaller, simpler components of it, and make sure you understand how they work.
In this case, the query is composed of a sub-query and a main query. Start by looking at the sub-query only. Display all rows and all columns of the sub-query.
Break apart the complicated components of that sub-query. Rnk depends on an ORDER BY clause, but the expression used in that ORDER BY clause isn't displayed anywhere. Copy and display just that expression. (I called this case_1_2 in the query below.) Even that may be too complicated to understand, so break it apart. Case_1_2 is formed by adding 2 smaller CASE expressions; in the query below, I displayed each of the in separate columns (case_1 and case_2).
So here's a query you might use to understand and debug the query I posted:

     SELECT     'ABC' AS c1, 10 AS c2 FROM dual     UNION ALL
     SELECT     'ABC',          20            FROM dual     UNION ALL
     SELECT     'FOO',          10            FROM dual     UNION ALL

For example, the first 12 rows of output show what we found when we were looking for ('ABC', 10). There were 12 rows in table x that had either ca='ABC' or c2=10 (or both). We used the rnk column to find the best match: lower numbers mean better matches. How did we do that? By using the DENSE_RANK function with a DESCending order by clause, that is, we used <tt> DENSE_RANK () OVER (... ORDER BY exp DESC) </tt>, which means that higher values of exp produce lower values from DENSE_RANK. What is exp? It's the column I called case_1_2. As you can see, when there was a perfect match ('ABC', 10), then case_1_2 had the value 3. Less perfect matches got lower values of case_1_2; for example ('ZZZ', 10) only had 2 in the case_1_2 column, and ('ABC', 5) only had 1. Why did case_1_2 have values of 3, 2 or 1 on those rows? Well, it's the sum of case_1 and case_2, so look at those individual columns, and see how they are computed.

Need help in rewriting a sql query

Can any one please tell me if there is any utility that can help me correcting the sql I have I need to tune the query as its taking lot of time. I want to use some tool that will help me re-formating the query.
Any help in this regard will be highly appreciated.

If you think that Oracle SQL Tuning Tools like SQL Tuning Advisor and SQL Access Advisor are not helping.
You might look into thrid party tools like Quest- SQL Navigator and TOAD.
But I don't advise this based on the following:

Oracle have enough tools of its own to satisfy the various needs.

Need help in Report From SQL Query

Hi All,
I am facing a problem with a report. I need your help.
I am creating a Report From SQL Query (Portal) with some arguments passed at runtime. I am able to view the output, if the query returns few rows ( arount 1000 rows). But for some inputs it needs to generate >15000 records, at this point the page is getting time out (i think!) and showing error page. I am able to execute query from the SQL Plus console ot using TOAD editor. Here the query is not taking more that 2 mins time to show the result.
If i am executing from Portal i observed that, once i give the appropriate input and hit submit button a new oracle process is getting created for the query on UNIX (I am usign "TOP" command to check processes). The browser page will be shown error page after 5 minutes (i am assuming session time out!) , but on the backend the process will be executed for more than 30 mins.
I tried also increase the page time out in httpd.conf, but no use.
The data returned as a result of the query is sized more than 10 MB. Is caching this much data is possible by the browser page? is the returned data is creating any problem here.
Please help me to find appropriate reasone for the failure?

There could be a variety of reasons for the delayed processing of this report. That includes parameter settings for that page, cache settings, network configurations, etc.
- explore best optimization for your query;
- evaluate portal for best performance configuration; you may follow this note (Doc ID: *438794.1* ) for ideas;
- third: for that particular page carrying that report, you can use caching wisely. browser cache is neither decent for large files, nor practical. instead, explore the page cache settings that portal provides.
- also look for various log files (application.log and apache logs) if you are getting any warnings reflecting on some kind of processing halt.
- and last but not the least: if you happen to bring up a portal report with more than 10000 rows for display then think about the usage of the report. Evaluate whether that report is good/useful for anything?

Need Help with Creating the SQl query

Hi,
SQL query gurus...
INFORMATION:
I have two table, CURRENT and PREVIOUS.(Table Defs below).
CURRENT:
Column1 - CURR_PARENT
Column2 - CURR_CHILD
Column3 - CURR_CHILD_ATTRIBUTE 1
Column4 - CURR_CHILD_ATTRIBUTE 2
Column5 - CURR_CHILD_ATTRIBUTE 3
PREVIOUS:
Column1 - PREV_PARENT
Column2 - PREV_CHILD
Column3 - PREV_CHILD_ATTRIBUTE 1
Column4 - PREV_CHILD_ATTRIBUTE 2
Column5 - PREV_CHILD_ATTRIBUTE 3
PROBLEM STATEMENT
Here the columns 3 to 5 are the attributes of the Child. Lets assume that I have two loads, One Today which goes to the CURRENT table and one yesterday which goes to the PREVIOUS table. Between these two loads there is a CHANGE in the value for Columns either 3/4/5 or all of them(doesnt matter if one or all).
I want to determine what properties for the child have changed with the help of a MOST efficient SQL query.(PARENT+CHILD is unique key). The Database is ofcourse ORACLE.
Please help.

Hi,
The last message was not posted by the same user_name that started the thread.
Please don't do that: it's confusing.
Earlier replies give you the information you want, with one row of output (maximum) per row in current_tbl. There may be 1, 2 or 3 changes on a row.
You just have to unpivot that data to get one row for every change, like this:
WITH     single_row AS

     ,     c.curr_child
     ,     c.curr_child_attribute1

     ,     c.curr_child_attribute3
     ,     DECODE (c.curr_child_attribute1, p.prev_child_attribute1, 0, 1) AS diff1
     ,     DECODE (c.curr_child_attribute2, p.prev_child_attribute2, 0, 2) AS diff2
     ,     DECODE (c.curr_child_attribute3, p.prev_child_attribute3, 0, 3) AS diff3
     FROM     current_tbl    c
     JOIN     previous_tbl   p     ON c.curr_parent     = p.prev_parent
                            AND c.curr_child     = p.prev_child

     OR     c.curr_child_attribute2     != p.prev_child_attribute2
     OR     c.curr_child_attribute3     != p.prev_child_attribute3
,     cntr     AS
     SELECT     LEVEL     AS n

What is your table structure? It is confusing. Post your sample input, output, table strucutre etc between {noformat}{noformat} and {noformat}{noformat}
And it looks like this.

I need help creating a formula that looksup cell data and give a value.

I want to have the table "At a glance" show the total days a driver has worked, there total in sales and there total in milage. The table shown is a example of what I want to have happen. I want to input any name into cell B2,C2,D2,ect. that is found in the row C2:C17 of Checkpoint (Truck 1) and Checkpoint (Truck 2) and return the total amount of day the driver has driven both trucks, The total in sales the driver has collected (Truck 1 and 2) and How many miles the driver has driven (Truck 1 and 2). I realize that these tables are not labeled correct. If I enter a name into B2 and the driver associated with that name hasnt driven then I want "N/A' to show in cell B2 and so one. I assume that the formula that is created for cell B2 will be copied and pasted into cell C2, D2, ect..
If someone could help me with this problem I'd really appreciate it.
Thanks.

Hi br,
To show the number of days worked by a driver, you need to COUNT the number of times that driver's name appears in row 2 of both tables.
To calculate his total sales and total mileage, you need to SUM the amounts he brought in each day and the distances he drove each day.
Your functions for this are COUNTIF and SUMIF.
Formulas in At a Glance:
B2: =COUNTIF(Truck 1 :: $3:$3,B$1)+COUNTIF(Truck 2 :: 3:3,B$1)
B3: =SUMIF(Truck 1 :: $3:$3,B$1,Truck 1 :: $5:$5)+SUMIF(Truck 2 :: $3:$3,B$1,Truck 2 :: $5:$5)
B4: =SUMIF(Truck 1 :: $3:$3,B$1,Truck 1 :: $12:$12)+SUMIF(Truck 2 :: $3:$3,B$1,Truck 2 :: $12:$12)
Fill all three formulas right to the last column of At a Glance.
To put N/A in place of the 0 in Roger's column and the empty columns, wrap each of the formulas in an IF statement:
Bn: =IF(AND(ISERROR(MATCH(B$1,Truck 1 :: $3:$3,0)),ISERROR(MATCH(B$1,Truck 2 :: $3:$3,0))),"N/A",formula)
Where formula is the formula used in column B above.

Barry

Need Help with Formula using SQL maybe

I need help! I work with Crystal reports XI and usually manage just fine with the Formula editor but his one I think will require some SQL and I am not good at that.
We are running SQL 2000 I think (Enterprise Manager 8.0) Our sales people schedule activities and enter notes for customer accounts. Each is stored in a separate table. I need to find activities that are scheduled 240 days into the future and show the most recent note that goes with the account for which that activity is scheduled.
The two tables, Activities and History, share the an accountID field in common that links them to the correct customer account.   I want to look at dates in the Startdate.Activities field more than 240 days in the future and show the most recent note from the History table where the accountid's match. I figure my query will contain a join on AccountID.Activities and AccountID.History used with Max(completedate.History) but I do not understand how to word it.
I would like to perform all this in crystal if possible. I humbly request your help.
Membery

You SQL would look something like this...
SELECT
a.AccountID,
a.BlahBlahBlah, -- Any other fields you want from the Activities table
h.LastComment
FROM Activities AS a
LEFT OUTER JOIN History AS h ON a.AccountID = h.AccountID
WHERE (a.ActivityDate BETWEEN GetDate() AND DateAdd(dd, 240, GetDate()))
AND h.HistoryID IN (
     SELECT MAX(HistoryID)
     FROM History
     GROUP BY AccountID)
This method assumes that the History table has a HistoryID that increments up automatically each time a new comment is added... So a comment made today would always have a higher HistoryID that one made yesterday.
If I'm wrong and there is no HistoryID or the HistoryID doesn't increment in a chronological fashion, it can still be done but the code is a bit more complex.

The correct way to handle this is to use bind variables.
And use DBMS_XMLGEN instead of DBMS_XMLQUERY :
create or replace procedure temp (
p_mtr_id       in varchar2
, p_from_date    in date
, p_through_date in date
is
l_xml   CLOB;
l_query VARCHAR2(2000);
l_ctx   dbms_xmlgen.ctxHandle;
begin
l_query:= 'SELECT

Help me write a SQL query; urgent

Hi, can somebody please help me write a SQL query.
I have 3 tables each with the same column names (Col1, Col2, Col3). Col1 is PK with Unique Constraint.
I wanted to add values of Col2 and Col3 (from all 3 tables) and put it in a separate table (i.e aggregated) of all values found in Col1.
Does anybody help me please ?
thanks alot.

Please don't mark your question as urgent. You've been around here long enough that you should know that it will not get your question anwered any faster, and may just irritate people into not answering at all.
I'm not sure exactly what you want.
Are you saying you want t1.c2 + t1.c3 + t2.c2 + t2.c3+ t3.c2 + t3.c3 for the rows that have the same c1 in all three tables?
If so, it would be like this, I think: insert into t4
select t1.c1
, t1.c2 + t1.c3 + t2.c2 + t2.c3+ t3.c2 + t3.c3
from t1, t2, t3
where t2.c1 = t1.c1
and t3.c1 = t1.c1If that's not what you want, please clarify.
And next time maybe you should post your SQL question in a SQL forum.
