Group Query Help
Oracle 10G version | R/2This is a Customers table and we will have to find they are elgible for product produced B or both or none.
But if you're serviceble by product B, it is certain that you will be good product a. (imagine the product A is greater coverage of Prouct and be produced is the smallest)
What I have done becomes the product of A B and get the remains that are usable for the product and not product B.

Hello
Thanks for posting the sample data in a useful form. That really helps.
So you want a query that produces a line of output for each value in the column state.
That's exactly what "State GROUP BY" don't:
SELECT state
, COUNT ( CASE
WHEN column_serviceable_a = 'Y'
AND column_color_a IN ('G', 'A')
THEN 1
END
)
- COUNT ( CASE
WHEN column_serviceable_b = 'Y'
AND column_color_b IN ('G', 'A')
THEN 1
END
) AS cnt
FROM cust_test
WHERE area_oo = 'Y'
AND area_h = 'Y'
GROUP BY state
ORDER BY state
;
In fact, this becomes 0 as the county when no line meets the criteria of "has".
If you prefer that NULL, as you posted, then replace the first indictment by AMOUNT:
SELECT state
, SUM ( CASE
WHEN column_serviceable_a = 'Y'
AND column_color_a IN ('G', 'A')
THEN 1
END
)
- COUNT ( CASE
WHEN column_serviceable_b = 'Y'
AND column_color_b IN ('G', 'A')
THEN 1
END
) AS cnt
FROM cust_test
WHERE area_oo = 'Y'
AND area_h = 'Y'
GROUP BY state
ORDER BY state
;
Output:
STATE CNT
---------- ----------
BANG
CHEN 2
HYD 1
Note that we do not need duplicate in this problem. Whenever you are tempted to use double, ask yourself why. See if the information you want to be taken from another table that you use when even.
This should be much faster than the original request. Instead of making 2 passes through the table for each status value (2 * 15 = 30 past total), just make a pass through the table.

I need help in writing a query. The data that I now contains three columns. The values in the first column have duplicate, and the 2nd column entries. The third is unique. Here is an example of the data that I have today:
Column1 Column2 Column3
Tier1 Group1 1
Tier1 Group1 2
Group level 1 2 3
Tier1 Group2 4
Group level 1 3 5
Level 1 Group 3 6
Expected result:
Column1 Column2 Column3
Tier1 Group1 1
2
2 3 Group
4
3 5 group
6
Thanks for your helpHello
Your front end that can probably not for you.
In SQL * Plus, for example:BREAK ON column1 ON column2 SELECT column1, column2, column3 FROM table_x ORDER BY column3 ;If you havd do in SQL, here's one way:
SELECT CASE WHEN ROW_NUMBER () OVER ( PARTITION BY column1 ORDER BY column3 ) = 1 THEN column1 END AS col1 , CASE WHEN ROW_NUMBER () OVER ( PARTITION BY column2 ORDER BY column3 ) = 1 THEN column1 , END AS col2 , column3 FROM table_x ORDER BY column3 ;I hope that answers your question.
If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
Highlight a few places where the queries above are getting incorrect results and explain, using specific examples, how you get the results of the data provided in these places.
Always tell what version of Oracle you are using.Published by: Frank Kulash, March 21, 2012 16:15

Want to get answers that work, or is it possible to get responses that cause errors?
Make sure that the INSERT statements you post too much work. Test (and, if necessary, correct) them before posting. All the instructions insert above have errors.
The query above (once you correct the spelling of PARTITION) returns all the lines after a date limit. It's always what you want, only the details of how calculated this date limit changed. In accordance with the new requirements, the closing date must be earlier than the actual lines dt_recv in there are not 2 (or more) with batch = 1 for any combination of (supplier_id, supplier_desc_id). All you have to do is change "r_num".<= 2"="" to="" "r_num="2" ,"="" when="" computing="" dt_cutoff,="" and="" return="" an="" impossiblly="" early="" date="" if="" there="" is="" no="" such="" row. ="" (i="" assume="" that="" dt_recv="" can="" not="" be="">
WITH got_r_num AS

GROUP BY label

If you would care to post CREATE TABLE and INSERT statements for your sample data, then I could test it.
Are you sure that the results you posted are what you want from data provided?
Is of the order of the elements in a significant list? In other words, when you say you want to get the results:
COMP1, COMP2
you'd be just as happy with
ORDI1, COMP2
? If the order is important, explains what this order.

And combine it with the query at the top of the page. But I also want to show all the other values, a.person_id, a.company, b.name for each line.
So my goal is to finally have:

1 vol., krog, food, 0
1 vol., krog, munch, 0
2, mols, flog, munch, 24
2, mols, flog, food, 0
2, mols, flog, 0
It's to have a default value of zero, where no join does exist for the value and do not duplicate anything even if I could always use separate.
Can anyone help with this?with t1 as ( select a.person_id, a.company, b.name, e.element, f.value from a, b, e, f where a.person_id = b.person_id and e.el_id = f.el_id -- e.t.c ), t2 as ( select e.element where e.name = 'EVALUE' ) select person_id, company, name, t2.element, sum( case t1.element when t2.element then value else 0 end ) value from t1, t2 group by person_id, company, name, order by person_id, company, name, t2.element /For example:

Hello
I'm new to the development of Oracle.
Oracle 10 g 2
My original query:
SELECT APP, count (*)
TRANSACTION
WHERE TYPE in ('ShipmentConfirmPR', 'ShipmentConfirm', 'ShipConfirm')
and the APP ("SAPPI", "SAPPI", "SAPR3") and INTERVENE ('9320 ', '9332','1208 ')
GROUP BY APP TYPE
order of the APP
the result of this query:
SAPPI 100
SAPPI 600
SAPR3 440
My requirement
And I want to have something like output
LDCS 100
TSW 600
PDC 440
IE.the APPP and STEP combinations. Must return the specified values
SAPPI & 9320-> LOC (here SAPPI IE APP is the same for both... but it's a coincidence IE APP can be sliced also)
SAPPI & 9332-> tsw
SAPR3 & 1208-> pdc
Options, I tried:
Query provided by one of the Forum members...
SELECT THE CHECK BOX
WHEN APP = "SAPP1" THEN DECODE (step, '9320', 'LSW', '9332', "TSW")
WHEN APP = "SAPR3" step = '1208' AND 'PDC '.
END app
COUNT (*)
TRANSACTION
WHERE TYPE in ('ShipmentConfirmPR', 'ShipmentConfirm', 'ShipConfirm')
AND THE APP ("SAPPI", "SAPPI", "SAPR3")
AND STEP IN ('9320', '9332', ' 1208')
GROUP BY APP, STEP
ORDER OF THE APP.

My Questions:
1.*There are indexes on all 3 APP passes it's IE, STEP and TYPE *. I don't want a FULL table Scan (as one would use the index). Can change us the query / use of indices, etc. to make it faster?
2. is the right to approach? Would the use of the concat operator in the function decode work better for my needs?
Something like
Select decode (APP |) STEP, 'SAPP9332', 'X') of TRANSACTION_HISTORY where < COND >
If Yes can you please provide the query?
3. ANY other approach / request for my requirement.

A full table scan might be the fastest way to get results. Do you have any reason to think that it would be faster to go through the index? How selective are the clues? In other words, what is the percentage of rows in the table correspond to each of the values in the WHERE clause?
2. is the right to approach?
It depends on what you're trying to do, which is not at all clear to me.
Would the use of the concat operator in the function decode work better for my needs?
Something likeSelect decode (APP |) STEP, 'SAPP9332', 'X') of TRANSACTION_HISTORY where
If you use this approach, look out for the problem Ab asse crevit . For example, if you have these 4 rows and 2 columns:
str1 str2 ---- ---- (NULL) FOO F OO FO O FOO (NULL)There are 4 values of distict of str1 (counting NULL) and 4 separate values of str2, str1 but | str2 is the same for each of them. In the above example, it there is no way to know, just by looking at the concatenated string, including str1 and str2 ends begins. Maybe it's not the case for your specific data (for example, if the application is still exactly 5 characters long). otherwise, you may need to add some kind of delimiter, like this
app || '+' || stepwhere you know that '+' never occurs in one of these columns.
3. ANY other approach / request for my requirement.
CASES, as I mentioned in your previous message:
Decode the help function
and as you have used above.In this thread, you said "I have to use the decode function. Why? It is a competition of school Etudieeo DECODE is explicitly required? Why you don't want in the best way, what that turns out to be?
Your WHERE clause:
AND APP IN ('SAPPI', 'SAPPI', 'SAPR3') AND STEP IN ('9320', '9332', '1208')admits 6 possible combinations of APA and step:
app step ----- ---- SAPP1 9320 SAPP1 9332 SAPP1 1208 SAPP3 9320 SAPP3 9332 SAPP3 1208but you are looking for only 3 of these combinations in DECODE it or the expression BOX. (Have 2 copies of 'SAPP1' e list won't do any good, but it does hurt real, either.)
By the way, is "SAPPI" app with the letter 'I' at the end, or "SAPP1", with the number '1' at the end?Published by: Frank Kulash, March 24, 2011 19:44

Hello
I have a requirement... can help you pleease
I have a table with two columns called Doc R, Seq R
Sampled data:
Type Doc R Seq R -------- --------- ------------ R R1 Null Q Q1 R1 R R2 Null Q Q2 R2 R R3 Null Q Null Null Now if you see first two records R1 and R2 have corresponding Q2..... if you see R3 dont have Q values.. Now i want the count of R3 like records where it does not have Corresponding Q values in ... any ideas please...Hello
Another way, which could be more efficient (but less clear):
WITH got_grp AS ( SELECT CASE WHEN rtype = 'Q' THEN seq_r ELSE doc_r END AS grp , CASE WHEN rtype = 'Q' THEN 0 ELSE 1 END AS r_val FROM yourtable WHERE rtype IN ('Q', 'R') ) SELECT COUNT (COUNT (*)) AS grp_cnt FROM got_grp GROUP BY grp HAVING COUNT (*) = SUM (r_val) ;You have not said if a line where
rtype = 'R' and doc_r has the value NULL is considered to be a match for a line where
rtype = 'Q' and seq_r is NULL.In the application of Cyn, they are not a match.
In the above query, they are.
A query can be changed for a different result. -
The point list - record group Query - bad alignment order
Dear all,
When I try to concatenate two columns using the query of the record group and display in the list item, the alignment is not in good condition.
For example; Here are the columns and data used in the process:
SHORT_DESC CODE_VALUE DESCRIPTION
---------------------------------------------------------------------------------------------------------------------------------------------------
ROLL1 customer - No accidental Production, by booking with another carrier, bad projection.
Roll2 client project - accidental l/c, B/L, customs, samples, AMS, LAR.
ABC - lack of vacuum ROLL3 lack of empty units.
ABC CDE ROLL4 - Roll on decision of the AGR RRR.
ROLL5 ABC XXX - Accidental IMO or denied OOG, operational problems, Cut & Run.
ROLL6 ABC YYY - booking fictitious material buffer, dummy booking.
This is the query of the record group used in forms:
----------------------------------------------------------------
PROCEDURE p_when_new_form_instance
IS
GROUP_ID recordgroup;
list_id question: = FIND_ITEM ('BLK_CONTROL.) LI_ROLL_REASON');
rg_name VARCHAR2 (20): = "LI_ROLL_REASONS";
status NUMBER;
l_query VARCHAR2 (4000);
BEGIN
l_query: =.
' SELECT rpad (short_desc, 50, "") | "| ''|| description of the description, code_value code_value OF codes WHERE code_value IN ("ROLL1", "roll2", "ROLL3", "ROLL4", "ROLL5", "ROLL6")';
GROUP_ID: = CREATE_GROUP_FROM_QUERY (rg_name, l_query);
status: = POPULATE_GROUP (GROUP_ID);
POPULATE_LIST (list_id, GROUP_ID);
EXCEPTION
WHILE OTHERS
THEN
pl_common.when_others;
END;
-----------------------------------
In addition, I have my property list item as the default "" MS SANS SERIF"fonts and when I run in Forms Builder get the alignment as below.
Result:
====
DESCRIPTION CODE_VALUE
Customer - Non-accidental. Production, by booking with another carrier, bad projection. ROLL1
Customer - Accidental | L/c, B/L project, customs, samples, AMS, LAR. ROLL2
ABC - lack of vacuum | Lack of empty units. ROLL3
ABC ORDER - to the reversal. Decision of the AGR RRR. ROLL4
ABC XXX - Accidental | IMO / denied OOG, operational problems, Cut & Run. ROLL5
ABC YYY - booking fictitious | Reservation of equipment, fake buffer. ROLL6
More high of the order is not the desired result because all the | (vertical bar) should display in the correct order as below.
Expected result:
==========
DESCRIPTION CODE_VALUE
Customer - Non-accidental. Production, by booking with another carrier, bad projection. ROLL1
Customer - Accidental | L/c, B/L project, customs, samples, AMS, LAR. ROLL2
ABC - lack of vacuum | Lack of empty units. ROLL3
ABC ORDER - to the reversal. Decision of the AGR RRR. ROLL4
ABC XXX - Accidental | IMO / denied OOG, operational problems, Cut & Run. ROLL5
ABC YYY - booking fictitious | Reservation of equipment, fake buffer. ROLL6
I tried and RPAD LPAD the alignment problem is still there; I know that the issue is due to the fixed length of the police.
But is there a solution to replace it it will be a great help.
So please help!
Thank you...
Kind regards
Sunil.GIf you can not use non proportional fonts, then forget about having any special alignment, because with proportional fonts, room occupied by each letter is different.

Hi all
I tried to use Dense_rank as below. But it gives me the top selling books. I need high library in each type...
This looks like a job for 'PARTITION BY type
For example:
WITH got_rnk AS
(
SELECT b.bid, b.type
SUM (o.quantity) AS total_quantity
DENSE_RANK () OVER ( PARTITION BY b.type
ORDER OF SUM (o.quantity) / / DESC
) AS rnk
B BOOK
o order1
WHERE b.bid = o.bid
GROUP BY b.bid, b.type
)
SELECT total_quantity, type submission
OF got_rnk
WHERE rnk = 1
;
. Aggregate functions (such as the SUM, above) are calculated before analytical functions, so an analytic function (such as DENSE_RANK above) may depend on an aggregate function; you don't need a separate subquery for that.

Hi all
I'm working on a query to the tables of dimensions. I want to be able to retrieve the total number of bytes and unused bytes for tables and their indexes. I also want to be able to combine all the output in several long strings to paste into simple rows of an Excel for analysis later. I could get that day:
DECLARE CURSOR size_cursor IS WITH obj_names AS ( SELECT s.owner, s.segment_name table_name, NULL, s.segment_type, s.partition_name, t.num_rows FROM dba_segments s, dba_tables t WHERE segment_type = 'TABLE' and t.table_name = s.segment_name and t.owner = s.owner UNION ALL SELECT s.owner, s.segment_name, NULL, s.segment_type, s.partition_name, t.num_rows FROM dba_segments s, dba_tables t WHERE segment_type = 'TABLE PARTITION' and t.table_name = s.segment_name and t.owner = s.owner UNION ALL SELECT i.owner, i.table_name, i.index_name, s.segment_type, partition_name, NULL FROM dba_indexes i, dba_segments s WHERE s.segment_name = i.index_name AND s.owner = i.owner AND s.segment_type = 'INDEX' ) SELECT * FROM obj_names; tbl_owner varchar2(32767); tbl_name varchar2(32767); index_name varchar2(32767); tbl_type varchar2(32767); row_count number; total_blocks_out number; total_bytes_out number; unused_blocks_out number; unused_bytes_out number; last_used_extent_file_id_out number; last_used_extent_block_id_out number; last_used_block_out number; BEGIN OPEN size_cursor; LOOP FETCH size_cursor INTO tbl_owner, tbl_name, index_name, tbl_type, part_name, row_count; EXIT WHEN size_cursor%NOTFOUND; dbms_space.unused_space( tbl_owner, COALESCE(index_name, tbl_nadme), tbl_type, total_blocks_out, total_bytes_out, unused_blocks_out, unused_bytes_out, last_used_extent_file_id_out, last_used_extent_block_id_out, last_used_block_out, part_name ); END LOOP; CLOSE size_cursor;ND;
Yet, cannot figure out how to group then tbl_owner and tble_name without inserting the results of cursor in a table, that I can't do. Any suggestions on how to perform the dbms_space.unused_space procedure to store without using a cursor? I have SQL Server I would be cheating by using sp_MSforeachtable, that would allow me to keep the results of the stored procedure as a relationship.
Thanks for any ideas or suggestions.
So I thought about my own questions by using the following query instead of the stored procedure...
select dba_tables.owner ,dba_tables.table_name ,dba_tables.num_rows "rows" ,sz + ex "Total reserved (KB)" ,dba_tables.num_rows*dba_tables.avg_row_len/1024 "data size (KB)" , sz "index reserved size (KB)" from (select table_name as table_name, sum(bytes)/1024 as sz ,max(pct_free) as free from dba_indexes inner join dba_extents on index_name=segment_name group by table_name) ix_space inner join dba_tables on ix_space.table_name=dba_tables.table_name inner join (select segment_name,sum(bytes)/1024 ex from dba_extents group by segment_name) ext on ext.segment_name=dba_tables.table_name
