How to repeat rows based on column value

Hi all,
I have a query that gives me a result with a column value for example 4.
I now want to repeat this row 4 times with a new column that calculated from 1 - 4.
Or when column value is 3 I want to repeat row 3 times with new column name 1-3
Can anyone help me with this please? :)

Hi Yvanlathem,
To achieve your requirement, you can reference the recursive approach as below.
DECLARE @T TABLE(Col1 CHAR(1),Col2 INT)
INSERT INTO @T VALUES('A',1),('B',2),('C',3)
;WITH Cte([Char],[Repeat]) AS
SELECT Col1,Col2 FROM @T
UNION ALL
SELECT [Char],[Repeat]-1 FROM Cte
WHERE [Repeat]>1
SELECT * FROM Cte ORDER BY [Char],[Repeat]
OPTION(MAXRECURSION 0)
/* Output
Char Repeat
A 1
B 1
B 2
C 1
C 2
C 3
If you have any question, feel free to let me know.

Combine rows based on column value

I'm trying to combine rows based off of a common value.
Table Data:
Result A
Player_ID   Player_Name Team_Name Points Sequence
99999       John Smith    Bulls              50         1
99999       John Smith    Pistons          14         2
What i want in the output
Result B
Player_ID Player_Name Team_Name Points
99999     John Smith      Bulls           64 (50 for Bulls)Here's my main query...
select player_id, player_name, team_name, points
from
          SELECT player_id, player_name, team_name, sum(points) sum_points
          FROM stats_data
          WHERE season_id = 2008
          AND points > 0
          GROUP BY player_id, player_name, team_name
          ) t
ORDER BY sum_points DESC, last_name;**The current query gives me the output from Result A
1) Not entirely sure how to combine data based of player_id
2) Once i figure out 1, im sure by adding the ('sum_points' for 'team_name') to the output can be done with a case statement, i think?

Sorry about that Frank.
Using: Oracle 10.2g
i was incorrect about the output of the query
          SELECT player_id, sum(points) sum_points
          FROM stats_data
          WHERE season_id = 2008
          AND points > 0
          GROUP BY player_id
)Output
Player_ID      Sum_Points
99999              20
55455               6
66489               2 So the subquery is outputing the correct data
The output of the original entire query(that you had posted) is:
Player_ID    Player_Name   Team_Name    Points
99999        John Smith      Bulls               16 (8 for Bulls)
55455        Bob Johnson    Rockets          6   (3 for Rockets)
66489        Chris Terry       Kings              2   (1 Kings)Here's some more raw sample data from the table:
Player_ID    Player_Name   Team_Name    Points     Sequence Game_Type_ID Team_ID
99999        John Smith      Bulls               12          1                       1                  5
99999        John Smith      Bulls               0            1                      -1                  5
99999        John Smith      Pistons            4           2                       1                 12
99999        John Smith      Pistons            0           2                       -1                12
55455        Bob Johnson    Rockets          4           1                        1                  3
55455        Bob Johnson    Rockets          0           1                       -1                  3
66489        Chris Terry       Kings              2           1                        1                  8
66489        Chris Terry       Kings              0           1                       -1                  8So your code frank is very close, the issue is that:
A) All players have a ('pt value' for 'team name') even if they played on the same team, which can prob. be solved with a case statement, which i tried to do in my last post.
WITH       grouped_data     AS
          SELECT player_id, sum(points) sum_points
          FROM stats_data
          WHERE season_id = 2008
          AND points > 0
          GROUP BY player_id
SELECT     g.player_id
,     s.player_name
,     s.team_name
(case when sequence = 2 then g.sum_points <==
     || '('
     || TO_CHAR (s.points)
     || ' for '
     || s.team_name
     || ')'
else to_char (g.sum_points)
END)     AS points
FROM     grouped_data     g
JOIN     stats_data     s     ON g.player_id     = s.player_id
WHERE     s.sequence     in (1,2)     <==
AND     s.season_id     = 2008
AND     s.points     > 0;the output has two issues, for players who played on more than one team, like Josh Smith the output comes out as
99999        John Smith      Pistons           20 (2 for Pistons)
99999        John Smith      Bulls               20While the players who played on one team came out correctly. So issue with my edit of your code is:
A) josh smith is output 2, needs to be output once
B)josh smith should say (Josh Smith Bulls 20 (4 for Pistons) not "99999 John Smith Pistons 20 (2 for Pistons)"
c) Issues with "99999 John Smith Pistons 20 (2 for Pistons)" is that it listing the wrong team for him: should be Bulls and listing half of his total with the pistons in the prentices should be 4. --The reason that is because s.points needs to be summed as based off of the data there's two entries
Hope this clears it up, thanks!

How to identfy rows with same column value

Hi
I have a table student
id ( pkey)
name
class
marks
i need to check the existence of duplicate values like
say the values are :
id name class marks
1 alan 6 85
2 victor 4 97
3 alan 6 85
i need to know if there is any matching row in the table --- like in this case id=1 and id=3 have same value for all the columns except for id .
so the result shud tell me the ids which have duplicate values for name , class , marks and also those ids for which there is no duplicacy
for id= 1 i see that id= 3 has same values
and id=2 has no duplicates
how do i show it ??
The result i expect is
name class marks count
alan 6 85 2
victor 4 97 1

You can use a self join to pull out the data which are almost duplicate without a column values here in this example without id the first and third records are duplicate.
select e.id,e.name,e.class,e.marks from EMP e,EMP d where e.name=d.ename and e.class=d.class and e.marks=d.marks and e.id<>d.id;

Change the row colors based on column values in MOSS 2007.

Count the number of rows based on the values!!!

Hi all,
What I am using:
I am working with a multidimensional database in Visual Studio 2010 using its Data source view and calculation member and dimension usage.
What I want to do:
I have a fact table that has five columns(leg(s),hand(s), Head and body,overall) that shows the category of how severe the injury is. Let say for the records all columns never have an empty value(no injury is stated with 'No injury' ) . These five columns
are connected with a dimension that has all the available values (Category A-E of injury).The overall has the most severe from the other four columns. I want to create a bar chart with five different measure
values, one for each column, and count the values in those columns.
For example : I have a slicer in the excel and a bar chart and the slicer has all the values of the Category of the injury ( Cat a,Cat B, Cat C, ... Cat E, No injury ) and when i select one of them, lets say
Cat C, the bar chart should update and show how many Cat C each measurement column has.
Example FACT table:
ID LEG HAND HEAD BODY OVERALL
1 No A No No A
2 No D C C C
3 E C D A A
4 E E B C B
So if i selected C the bar chart will count (Leg = 0, Hand = 1, Head = 1, body = 2 and Overall = 1).
Any ideas ?
Thanks for the help and the time :)

Hi DBtheoN,
According to your description, you want to create a chart on excel worksheet to count the rows based on the value, right? If in this case, I am afraid this issue is related to Office forum, I am not the expert of Office, you can post the issue on the corresponding
forum.
However, this requirement can be done easily on SQL Server Reporting Services. You can using the expression below to count the rows.
=COUNT(IIF(Fields!LEG.Value=Parameters!TYPE.Value,1,NOTHING))

Color report rows based on a value in that row

I would like to Color report rows based on a value in that row.
For examplle with the "EMP" table:
I would like job=MANAGER to be red and job=CLERK to be green etc etc
The other example I found only had the option of one color either the highlight or the default color.
I am looking for a way to do multiple colors.

Hi,
In the row template, you can use #1#, #2#, etc to indicate where a field in the report needs to be output. This does not have to be plain text - ie, you can use it within style tags if you like.
So, take a query like:
SELECT EMPNO,
ENAME,
DEPTNO,
DECODE(DEPTNO, 10, 'green', 20, 'red', 30, 'cyan', 'white') BG_COLOUR
FROM EMPYou get columns 1=empno, 2=ename, 3=deptno and 4=bg_colour. In the row template, you can then do:
Before Rows setting (sets up the table):
<table>
<tr><td>ID</td><td>Name</td><td>Dept</td></tr>After Rows setting (closes the table):
</table>Row Template 1 (used for ALL rows):
<tr style="background-color:#4#;"><td>#1#</td><td>#2#</td><td>#3#</td></tr>Then, for every row, the colour that has been calculated using the DECODE function will be used in the style tag to colour the background for the entire row.
How you determine the colours is up to you. I've used DECODE here, but you could use a field on the DEPT table to hold this and use this in your SQL statement.

How to dynamic select based on runtime value ?

how to dynamic select based on runtime value ?
I want to write a select function, which do selecting based on parameters. eg,
CREATE OR REPLACE FUNCTION myfunction
(tableName VARCHAR2, pkName VARCHAR2, pkValue VARCHAR2, requestString VARCHAR2)
RETURN VARCHAR2 AS
BEGIN
select requestString from tableName where pkName=pkValue;
RETURN NULL;
END;
myfunction('users', 'user_id', '100', 'user_name'); it will select 'user_name' from table 'users' where 'user_id' = '100'.
This way could save lots of coding. but it can't pass compiler. how to work out ?
Thanks.

While this may save code, if used frequently it will be ineffecient as all [explicative deleted]. The danger is that it would be used even for repeatable statements.
This mode of operation ensures that every statement [calling the funciton] needs to be reparsed, which is extremely expensive in Oracle (in CPU cycles, recursive SQL and shared pool memory).
Such reparsing is rarely a good thing for the environment ... it could easily lead to buying more CPU (bigger box) and therefore adding more Oracle license ... which could quickly exceed the typical developer's salary.
However - if you really, really want to do this, look up 'execute immendiate' in the PL/SQL manuals.
