Need help with Oracle SQL merge records according to date and term dates

Hi all

I need help to find this little challenge.

I have groups and flags and effective dashboards and dates of term against these indicators according to the following example:

GroupName	Flag_A	Flag_B	Eff_date	Term_date
Group_A	THERE	THERE	20110101	99991231
Group_A	N	N	20100101	20101231
Group_A	N	N	20090101	20091231
Group_A	N	N	20060101	20081231
Group_A	N	THERE	20040101	20051231
Group_A	THERE	THERE	20030101	20031231
Group_B	N	THERE	20040101	99991231
Group_B	N	THERE	20030101	20031231

As you can see, group_A had the same combination of (N, N) flag for three successive periods. I want to merge all the time periods with the same indicators in one. Where entry into force will be the most early (underlined) time period and end date will be later (underlined)

So the final result should look like this:

GroupName	Flag_A	Flag_B	Eff_date	Term_date
Group_A	THERE	THERE	20110101	99991231
Group_A	N	N	20060101	20101231
Group_A	N	THERE	20040101	20051231
Group_A	THERE	THERE	20030101	20031231
Group_B	N	THERE	20030101	99991231

Thanks for your help

Here's the DDL script

drop table TMP_group_test;

create table TMP_group_test (groupname varchar2 (8))

, flag_a varchar2 (1)

, flag_b varchar2 (1)

, eff_date varchar2 (8)

, term_date varchar2 (8)

);

insert into TMP_group_test values ('Group_A', 'Y', 'Y', ' 20110101 ', ' 99991231');

insert into TMP_group_test values ('Group_A', 'n', ' n ', ' 20100101 ', ' 20101231');

insert into TMP_group_test values ('Group_A', 'n', ' n ', ' 20090101 ', ' 20091231');

insert into TMP_group_test values ('Group_A', 'n', ' n ', ' 20060101 ', ' 20081231');

insert into TMP_group_test values ('Group_A', 'n', 'Y', ' 20040101 ', ' 20051231');

insert into TMP_group_test values ('Group_A', 'Y', 'Y', ' 20030101 ', ' 20031231');

insert into TMP_group_test values ('Group_B', 'n', 'Y', ' 20040101 ', ' 99991231');

insert into TMP_group_test values ('Group_B', 'n', 'Y', ' 20030101 ', ' 20031231');

It is the closest, I went to the solution

I create two rows;

Rnk1: partition by group name, order of eff_date / / desc: this grade will sort the records of the most recent and handed to zero for each group\

Rnk2: (dense) partition by group name, flag_A, flagb: this grade for each combination of group\flag gives a number so that they are classified as "families".

Then I use the function analytic min

Min (eff_date) more (partition of GroupName, rnk2): the idea is that, for each Member of the same family, the new date is the min of the family (and the max for the date of the term), at the end I just need separate so that the duplicates are gone

Now the problem. As you can see from the query below, records of 1 and 6 (as identified by rownum) are identified in the same family, because they have the same combination of flag, but they are not successive, so everyone must keep its own date of entry into force.

If only I can make the distinction between these two that would solve my problem

Query:

Select rowNum,GroupName, flag_a, flag_b, eff_date, term_date, rnk1, rnk2

, min (eff_date) more than (partition by GroupName rnk2( ) min_eff

(

Select rowNum,

GroupName , flag_a , flag_b , eff_date , term_date

rank() more than (partition by GroupName stopped by eff_date desc) rnk1

DENSE_RANK() more than (partition by GroupName order by flag_A flag_B ( ) rnk2

de dsreports . tmp_group_test

) order by rowNum

Hi KSI.

Thanks for your comments, you were able to distinguish between these lines highlight, but lost lines 2,3,4 which are supposed to have the same date min = 20060101.

Please see the table wanted to see the final result I want to reach

Thanks again

This first answer is basically correct, but in the main query, you want to use the function MIN, not the analytical function aggregation and GROUP BY columns with common values, like this:

WITH got_output_group AS

(

SELECT GroupName, flag_a, flag_b, eff_date, term_date

ROW_NUMBER () OVER (PARTITION BY GroupName

ORDER BY eff_date

)

-ROW_NUMBER () OVER (PARTITION BY GroupName, flag_a, flag_b)

ORDER BY eff_date

) AS output_group

OF tmp_group_test

)

SELECT GroupName, flag_a, flag_b

MIN (eff_date) AS eff_date

MAX (term_date) AS term_date

OF got_output_group

GROUP BY GroupName, flag_a, flag_b

output_group

ORDER BY GroupName

eff_date DESC

;

The result I get is

GROUP_NA F F EFF_DATE TERM_DAT

-------- - - -------- --------

Group_A Y 20110101 99991231 Y

N Group_A 20101231 20060101 N

Group_A N 20051231 20040101 Y

Group_A Y Y 20031231-20030101

Group_B N Y 99991231 20030101

which is what you asked for.

Hello gurus,

I would really appreciate your time and effort on this application. I have the following data set.

Please ignore '-' added for clarity

I'm writing a paid_amount based on Reference_No, Check_Number, Payment_Date, Invoice_Number, aggregate query Invoice_Type, Vendor_Number and display description with Invoice_type 'I' when there are multiple records with the same Reference_No, Check_Number, Payment_Date, Invoice_Type, Invoice_Number, Vendor_Number. When there are no more records I want to display the respective Description.

The query should return the following data set

Need help with PL/SQL so and then select

Hello guys, I am new to the PL/SQl programming (only Java experience) and I'm pretty stuck to my task. It would be great if you could help me. I am in programming with Oracle SQL * Plus Version 10.2.0.3.0
Whenever a user logs on to the server a database entry is created with information about the logged-on user. I need to create a PL/SQL command that selects all the information from last month. Unfortunately, the date_stamp column has a certain weird format: 1131210 for December 10, 2013

My idea so far:

DECLARE
v_today NUMBER;
BEGIN
v_today: = TO_NUMBER (TO_CHAR (SYSDATE, 'MM')); -Save the number of the month (e.g.12) in v_today
IF v_today = 01 THEN
SELECT * from audittrl
WHERE the date_stamp between 1131201 AND the 1131231;
ELSIF v_today = 02 THEN
SELECT * from audittrl
WHERE the date_stamp between the 1130131 AND 1130101;
.......
END IF;
END;
/
Error code: "an INTO clause in this SELECT statement.
I do not want to save the result to select a variable, hope you can help me. Thanks in advance.

Thanks, I'll try that, if still get caught once, I'll be back. Anway I'm not sure of the solution of Chris227, because I can't test it right now. From my point of view it gives you information the current month (e.g., December) and not the month previous (-online November), or have I missed something. ?

You are right. In addition, it does not for a given year. If you have data from several years in the table, it will select lines for the month of December 2012, 2011, 2010,... but also of 2013.

Here's a way to get around that:

DECLARE

prev_month_start PLS_INTEGER: = TO_NUMBER (TO_CHAR (ADD_MONTHS (SYSDATE-1)

, "YYMM"1' "01"

)

);

this_month_start PLS_INTEGER: = TO_NUMBER (TO_CHAR (SYSDATE

, "YYMM"1' "01"

)

);

BEGIN
FOR (IN) rec
SELECT *.
Of audittrl
WHERE the date_stamp > = prev_month_start
AND date_stamp< >
ORDER BY user_id, date_stamp - or other

)
LOOP
dbms_output.put_line (rec.date_stamp);
dbms_output.put_line (rec.event);
dbms_output.put_line (rec.user_id)
dbms_output.put_line (rec.host_name);
END LOOP;
END;

This should also be more effective, because it will allow the optimizer to use an index on date_stamp. Even if there is no index, it will be more effective because it avoids calling any function (for example, SUBSTR) on each line of the table.

You needn't PL/SQL to get these results. Just use SQL, you might say:

SELECT event, host_name, user_id and date_stamp
Of audittrl
WHERE the date_stamp > = TO_NUMBER (TO_CHAR (ADD_MONTHS (SYSDATE-1)
, "YYMM"1' "01"
)
)
AND date_stamp< to_number="" (="" to_char="" (="" sysdate="" to_number="" (="" to_char="" (="">

, "YYMM"1' "01"
)
)

ORDER BY user_id, date_stamp - or other

;

Your front end will provide column headers and touch the data so that the columns line up. It can also set the output to a file. (For example, if your front-end is SQL * Plus, you can use the command of the COIL.)

I guess date_stamp is a NUMBER. If it is a string, the solutions above can be simplified a bit.

This problem (and many other problems) would be so much simpler if date_stamp was a DATE column. Using numbers or strings to store the date information is simply asking for trouble.

I need help with a query that need access to data from 3 tables. That's what I did

Help with oracle sql to get all possible combinations in a table.

Hello guys I have a small predicatement which has me a little confused. I have a table similar to the following. (It is a sample of my real of the table. I use this to explain the original table containing sensitive data).

CREATE TABLE TEST01( 
TUID VARCHAR2(50),
FUND VARCHAR2(50),
ORG  VARCHAR2(50));

Insert into TEST01 (TUID,FUND,ORG) values ('9102416AB','1XXXXX','6XXXXX');
Insert into TEST01 (TUID,FUND,ORG) values ('9102416CC','100000','67130');
Insert into TEST01 (TUID,FUND,ORG) values ('955542224','1500XX','67150');
Insert into TEST01 (TUID,FUND,ORG) values ('915522211','1000XX','67XXX');
Insert into TEST01 (TUID,FUND,ORG) values ('566653456','xxxxxx','xxxxx');

"TUID"                        "FUND"                        "ORG"                         
"9102416AB"                   "1XXXXX"                      "6XXXXX"                      
"9102416CC"                   "100000"                      "67130"                       
"955542224"                   "1500XX"                      "67150"                       
"915522211"                   "1000XX"                      "67XXX"                       
"566653456"                   "xxxxxx"                      "xxxxx"

The 'X' is wildcard character elements * (I inherit it and I can not change the table format) * I would like to make a query as follows

select tuid from test01 where fund= '100000' and org= '67130'

However I like to do is to retrieve all the records that have have these segments in them including ' x
in other words the output expected here would be

"TUID"                        "FUND"                        "ORG"                         
"9102416AB"                   "1XXXXX"                      "6XXXXX"                      
"9102416CC"                   "100000"                      "67130"                       
"915522211"                   "1000XX"                      "67XXX"                       
"566653456"                   "xxxxxx"                      "xxxxx"

I started to write a massive sql statement that would have the 12 as the instruction inside, because I must compare the org and finance every possible way.
This is where im headed. but im wondering if there is a better way.

select * from test02
where fund = '100000' and org = '67130'
or fund like '1%' and org like '6%'
or fund like '1%' and org like '67%'
or fund like '1%' and org like '671%'
or fund like '1%' and org like '6713%'
or fund like '1%' and org like '67130'
or fund like '10%' and org like '6%'...etc

/*seems like there should be a better way..*/

can someone give me a hand to come with this sql statement...

the last item should be excluded. The second digit in "org" is a "7".

Fund is bad, too. Looking for 6 characters ("100000"), but the funds on this line is 7 characters ("1XXXXXX").

and it's always get picked up.

That's why you should use the Joker _ instead of %

select  tuid, fund, org
from    test01
where  '100000' like translate (fund, 'xX', '__')
and    '67130'  like translate (org,  'xX', '__')

It is difficult to see, but in two calls to TRANSLATE, the 3rd argument is a string 2 ' _.

OK, I'll do my first point and click on the flash game to familiarize myself with some databases.
I set up a room with a walls (rooms) 2 for the moment and on the first picture there is 4 screws which, when clicked play a small animation and are then removed, works great so far. But if I leave this room and go back inside the screws are back in their original position.

Instead of having this code to remove them, you can try to let them withdraw. In the last picture (24) within each mc live, try to use...

MovieClip (parent) .removeChild (this);

Need help with a SQL qurey that returns multiple lines for a record?
I have the following query where I use a WHEN clause CASES to determine the date of a change that starts with 'FRLO' on day 1 - day14 of the pay period. It works fine if a folder schedule with a day that begins "FRLO", but if more than one day is "FRLO" then it only returns the first day he finds and not others. Is there a way to get the query to return a ron for every day 1-14 that begins "FRLO"? System if Oracle 11 G
The order of the results is not important, because this is part of a larger query that orders the results.

Thanks in advance for any help,
George

Need help with basic sql

Hello

I use oracle 10g and having some small doubts associated with sql, goes here of the situation

I have a Transaction table, which contains the records/operation made by an employee under a code of pattern on different dates, see below examples of data

EMP_CODE          REASON_CODE     DATE

A001           B1                            1st Jan 2009
A001          B1          3rd Jan 2009
A001          B1          6rd Jan 2009
A001          C2          9th Jan 2009

A002          D4          1st Jan 2009
A002          D4          3rd Jan 2009
A002          D5          6rd Jan 2009

A003          E6          6rd Jan 2009
A003          E6          7rd Jan 2009

Actually I want to have the final result as follows (p. ex. some how hide A003, see below for reason)

A001          B1
A001          C2
A002          D4
A002          D5

So basically, print employee ID and reason code only if the employee has made the transaction under more than 1 code of reason, since the employee "A003" completed transaction code Minus 1 SINGLE code ONLY reason *, I don't want his record in printed.*

the current query I wrote is as follows:

select      emp_cd, reas_cd
from      employee_trans_table
where     reas_cd <> '   '
group by emp_cd, reas_cd
order by emp_cd, reas_cd

but this impression of results as

A001          B1
A001          C2
A002          D4
A002          D5
*A003          E6*

How to avoid printing A003/E6 since she had only 1 reason code attached to it...

I hope that I am able to clearly state the doubt that I am, let me know if you need any other info/clarrification on it.

Need help with Oracle Database Backup & Restore Cold

Environment:
Oracle Version: 11.2.0.4
Platform: AIX
A few weeks ago, I had updated my Oracle 10.2.0.1 to 11.2.0.4 database. The customer changed his mind and now I downgrade to 10.2.0.1. Unfortunately, the compatibility setting is set to 11.2.0.4. So I can't use the lower upgrade scripts.
I had taken a cold backup of the database before the upgrade. Unfortunately, I missed save logs for recovery.
Is there a way I can always downgrade / recovery 10.2.0.1 with cold back? or is it simply not possible without the backup of redo logs.
Thanks in advance.
rogers42

I had taken a cold backup of the database before the upgrade. Unfortunately, I missed save logs for recovery.

And what do YOU mean by "had taken a cold backup"?

Because in addition to what John said, you also need the correct initialization file.

Do you have a return of this init file which was taken at the same time as the backup?

I had updated my Oracle 10.2.0.1 to 11.2.0.4 database.

I suggest that you first reinstall the 10.2.0.1 version or Oracle before recovering your cold backup.

You must use the EXACT name of the folder structure and file that have been used originally.

See my response in this thread a few years ago:

Re: Restore incompatible cold backup

You will be able to simplify this process, some given that your backup is consistent, but the steps should help you to understand what to do.

One of my answers in THIS thread has real details for each of the steps in the other thread

Need help with PL/SQL code
Hi I am writing this code in pl/SQL:

create or replace
PROCEDURE 'TESTPRI '.
(NUMBER pCYC_DT)
AS
vTGT_TABL VARCHAR2 (25);
vSTG_TABL varchar2 (30);
vsql varchar2 (200);
BEGIN
vTGT_TABL: = 'TESTTABL ';
vSTG_TABL: = vTGT_TABL | » _'|| pCYC_DT;
vsql: = 'TRUNCATE TABLE ' | vTGT_TABL;
EXECUTE IMMEDIATE vsql;
RUN IMMEDIATELY "INSERT" | vTGT_TABL | ' SELECT * FROM '. vSTG_TABL;
COMMIT;
-IMMEDIATE 'TRUNCATE TABLE ' | vSTG_TABL;
END TESTPRI;

When executing this procedure it gives me following error:
ORA-03290: Invalid command truncate - lack of key word TABLE or CLUSTER
ORA-06512: at "DBR. TESTPRI', line 11
ORA-06512: at line 6

But I think that the TRUNCATE TABLE statement is correct. Is there a problem with the variable?

Any help would be appreciated.
Thank you.
vsql: = 'TRUNCATE TABLE ' | vTGT_TABL;

You need space after the TABLE
```
vsql:= 'TRUNCATE TABLE ' ||vTGT_TABL ; 
```
EXECUTE IMMEDIATE vsql;
RUN IMMEDIATELY "INSERT" | vTGT_TABL | ' SELECT * FROM '. vSTG_TABL;

Sapce here after INTO, before SELECT and FROM
```
EXECUTE IMMEDIATE 'INSERT INTO '|| vTGT_TABL||' SELECT * FROM '|| vSTG_TABL;
```

IP number looking for PSI - need help with a sql solution better and faster

Hello

I have a table (one) with more 1 000 000 IP addresses and numbers (the digital equivalent of the IP address)

I have a second table (b) which contains a mapping between the ranges of the ISP and IP. The table looks like this and more contains 150 000 entries:

BEGIN_IP_RANGE END_IP_RANGE ISP_NAME

-------------------------- ---------------------- --------------

600000000 700000000 ISP_X

800000000 900000000 ISP_Y

I'm creating a third table (c) which connects (a) IP numbers to identify the ISP from (B). The query looks like this:

CREATE TABLE c

Select a.IP_ADDRESS

b.ISP_NAME

IP_NUMBERS a, ISP_LOOKUP b lkp

where a.IP_NUMBER between b.BEGIN_IP_RANGE and b.END_IP_RANGE

;

There is no key join between the 2 tables and so I use TO search for the access provider. The performace of it's terrible and table (c) takes several hours to create.

Does anyone have any thoughts/ideas/suggestions on how this research can be achieved by using a solution better and faster?

Thank you very much

Shah

Need help with a SQL

Hi Experts,
I have a table W_data where there are 2 fields (1) business_date and (2) ID Business_date is a date field havgnd dates daily while id is to have an id associated with each date. So, for a date, there is always a single record.
I need to write a query so that I can retrieve the records for every sixth month by selecting the date of the minimum activity.
Please advice.
Thanks in advance.

So far you have not posted an expected output.

If you would like the earliest date in each half of the year and its corresponding ID, then

Select min (WAH_BUSINESS_DATE), min (id), Dungeon (dense_rank of the first order by WAH_BUSINESS_DATE)

of w_data

Trunc ((to_number (to_char (WAH_BUSINESS_DATE, 'yyyyq') Group) + 1) / 2).

Trunc (to_number(to_char...)) is to get a separate value for each semester, convert a different value of Q1 2013 and 2013 Q2 in a value and 2013 Q3 Q4 2013.

On your published data, which gives:

Date ID

Need help with oracle query

Hello
I have a customer as requirement below
We have the table header and contains data such as
ID, custname, socket
101, raju, 514
102, ratna, 12
103, rakesh, 16
104, joseph, 129
and we mappingtable like below as
sampval, socket
244094,512
244095,2
244096,4
244097,8
244098,16
244102,128
244103,1
If header.mapvalue is 514 analysis then it out on the mappingtable basis to be exported for a value of 244094. 244095.
Header.mapvalue is 12 parsing it out based on mappingtable to be exported for a value of 244096. 244097 and so on...
Could you please help me how to get the functionality in a database query.
Thanks in advance

Try to query below and let me know

SELECT id,

custName,

HT.mapvalue,

req_val

From ht header_tbl,

(SELECT SAMPVAL,

socket,

CITY,

SUMVAL,

REQ_VAL

Of

(SELECT SAMPVAL,

socket,

CITY,

SUMVAL,

REQ_VAL,

ROW_NUMBER() over (ORDER BY lvl SUMVAL PARTITION) rn

Of

(SELECT sampval,

socket,

City,

LEVEL lvl,

CASE

WHEN ((= LEVEL 2)

AND (socket = socket connect_by_root))

THEN socket

ANOTHER socket + connect_by_root socket

END as sumval,

CASE

WHEN ((= LEVEL 2)

AND (socket = socket connect_by_root))

THEN TO_CHAR (sampval)

Of OTHER TO_CHAR (CONNECT_BY_ROOT sampval

||'|'

|| sampval)

END AS req_val

A mapping

CONNECT BY LEVEL<=>

)

WHERE the lvl = 2

)

WHERE rn = 1

) qry_rslt

WHERE ht.mapvalue = qry_rslt.sumval;

An alternative with xmlagg, you can use this query to achieve your requirement

SELECT id, custname, RTRIM (xmlagg (xmlelement(e,mp.sampval||'|')). Extract ('//Text ()'),'| ') req_val

From header_tbl, mapping mp ht

WHERE mp.mapvalue = BITAND (mp.mapvalue, ht.mapvalue)

GROUP BY id, custname;
