Count of rows from different tables.
Hi Friends,
I have 4 tables with a common column name "ID". I would like to get the count of rows from all the four tables which has the same ID.
Ex

Different number of rows for different columns in JTable
hi
I need to create a JTable with different number of rows for different columns...
Also the rowheight should be different in each column...
say there is a JTable with 2 columns... Col1 having 5 rows and column 2 having 2 rows...
The rowHeight in Col2 should be an integer multiple of Rowheight in Col1
how do I do this ??
can anybody send me some sample code ?????
thanx in advanceHow about nesting JTables with 1 row and many columns in a JTable with 1 column and many rows.
Or you could leave the extra columns null/blank.
You could use a GridBagLayout and put a panel in each group of cells and not use JTable at all.
It would help if you were more specific about how you wanted it to appear and behave. -
Find MIN, MAX of multiple rows from multiple columns
Hello,
I need to figure out how to pull the MIN/MAX of multiple rows from multiple columns into one column. Even if some are NULL/blank.
For Example: (C: Column, R: Row, N - NULL/Blank)
C:____1____2____3____ 4____Max
R:____20___22___13____4____*22*
R:____N____N____32____14___*32*
R:____N____12____N____N____*12*
That is, it always gives a value for MIN/MAX unless there are NO values in all the rows of the columns.
So if there is one value, it will select that for the MIN/MAX, as it's the smallest/biggest since there is nothing to compare it to.
Here is my current code:
CASE WHEN COLUMN 1 < COLUMN 2 THEN COLUMN 2 ELSE COLUMN 1 ENDHi Thank you for your feedback, unfortunately, I just found out that EVALUATE Function is disabled in our environment for security reasons, so the only other way I've discovered is this:
The problem is that none of the conditions in the case statement are met--so the column is set to null. You can add a WHEN statement (section 2 below) to catch the nulls. There are five cases to consider:
Case 1: begin insp > bad order
Case 2: begin insp < bad order
Case 3: bad order only (begin insp is NULL)
Case 4: begin insp only (bad order is NULL)
Case 5: both begin insp is NULL and bad order is NULL
1) If bgn-crm-insp-ob > report-bo-ob then bgn-crm-insp-ob
(Case 1)
CASE WHEN filter ("- Terminal Task Measures"."Task Reported DateTime (Local)" using "Task Detail"."Task Code" = 'bgn-crm-insp-ob') > filter ("- Terminal Task Measures"."Task Reported DateTime (Local)" using "Task Detail"."Task Code" = 'report-bo-ob') THEN filter ("- Terminal Task Measures"."Task Reported DateTime (Local)" using "Task Detail"."Task Code" = 'bgn-crm-insp-ob')
2) If report-bo-ob is NULL then bgn-crm-insp-ob
(Case 4, 5) for case 5, you will get NULL
WHEN filter ("- Terminal Task Measures"."Task Reported DateTime (Local)" using "Task Detail"."Task Code" = 'report-bo-ob') IS NULL THEN filter ("- Terminal Task Measures"."Task Reported DateTime (Local)" using "Task Detail"."Task Code" = 'bgn-crm-insp-ob')
3) Else report-bo-ob
(Cases 2, 3)
ELSE filter ("- Terminal Task Measures"."Task Reported DateTime (Local)" using "Task Detail"."Task Code" = 'report-bo-ob') END
Hopefully this works, I'll give feedback if it does, or if you have any further suggestions please submit, again, THANK YOU SO MUCH ANYWAYS! -

How to convert Rows to different columns
Hi All,
I am having a table address with the following data.
ID REL_NAME REL_RELATION REL_PHONE
1--- kish_rel1--- wife--- 1111
1--- kish_rel2--- sister--- 2222
1--- kish_rel3--- brother--- 3333
2--- ram_rel1--- brother--- 4444
Now i want to display rows data into columns. See the output i want. Exactly, I dont know how many rows are there for each ID. It may increase or decrease.
ID REL_NAME REL_RELATION REL_PHONE
1---kish_rel1--- wife--- 1111---kish_rel2--- sister--- 2222---kish_rel3--- brother--- 3333
2---ram_rel1--- brother--- 4444
Thanks in advance,
PalHi,
I have found this is useful. But it is static. It wont work if we dont know the maximum number of rows present when grouped by ID.
Is there any other solution, which will give correct values, if we dont know the row count when grouped by ID.
SELECT hrid,
MAX(case when seq=1 then rel_name end) AS "rel_name1",
MAX(case when seq=1 then rel_relation end) AS "rel_relation1",
MAX(case when seq=1 then rel_phone end) AS "rel_phone1",
MAX(case when seq=2 then rel_name end) AS "rel_name2",
MAX(case when seq=2 then rel_relation end) AS "rel_relation2",
MAX(case when seq=2 then rel_phone end) AS "rel_phone2",
MAX(case when seq=3 then rel_name end) AS "rel_name3",
MAX(case when seq=3 then rel_relation end) AS "rel_relation3",
MAX(case when seq=3 then rel_phone end) AS "rel_phone3",
MAX(case when seq=4 then rel_name end) AS "rel_name4",
MAX(case when seq=4 then rel_relation end) AS "rel_relation4",
MAX(case when seq=4 then rel_phone end) AS "rel_phone4"

Changing rows into different column names
Hi,
i need to tranpose the rows into differnent column names
my sample data :
id , val
1 3
1 4
1 5
into
id , val1, val2 , val3 , val4 ... valn ..
1 3 4 5
from askTom's i see that it's tranpose into a single column using the ref cursor ?
how can i do made it into different column names ?
kindly advise
tks & rdgsFor example, lets say that you want to order your columns from least value to greatest and that you'll never have more than three values per id. Then you can use the analytic function row_number() like this to create a pivot value.
select id, val,
row_number() over (partition by id order by val) as rn
from your_table;And so your pivot query ends up looking like this.
select id,
max(case when rn=1 then val end) AS val1,
max(case when rn=2 then val end) AS val2,
max(case when rn=3 then val end) AS val3
from (
select id, val,
row_number() over (partition by id order by val) as rn
from your_table
group by id;But notice that I started out by making up answers to Justin's questions. You'll have to supply the real answers. -
Distinct data from different columns of a table-Single query
I have a table with different columns. Each of these columns have entries. A particular column, say, a column called name can have same entries more than one time. Likewise other columns can also have same entries more than once. My requirement is to have distinct entries from each of these columns using a single query, such that , for eg; the name column will contain the name George only once on retrieval. Place column will have the place Newyork only once...like that...but Newyork and newyork should be treated different(likewise in other columns also ie; case sensitive). I want to retrieve the above said using a single query from a table. Kindly help.

Count distinct rows from an internal table
Hi,
i have an internal table containing pairs of entries like
1 1
1 2
1 3
2 1
2 2
What i want to do is to determine the value of rowcount from first column ( here it would be 2 and not 5 ) - to me it seems like a DISTINCT. Any suggestions for that ?
ClemensHi clemens,
1. One of the ways is to use COLLECT.
2. suppose your original internal table is ITAB.
Create one more with just one field
STAB eg.
3. Loop at ITAB.
STAB-field1 = ITAB-Field1.
COLLECT stab.
ENDLOOP.
4. In stab u will have only TWO records,
1
2

Getting 2nd Least Value from Different Column
Hi there All,
I have one odd requirement.
I hava table which has diffrent columns of numeric Datatype.
The task is to get the least values from the table.
I can take the least value by least(col1,col2,col3 ...) function.Until this stage it is fine.
But also I have take 2nd least value and 3rd least value, which I am quite unsure how to get it.
Looking forward for suggestions.
Thanks in Advance.
Regards,
AjeetThe following is a generic solution that will allow you to select the nth least and allow you to pass as many column names as you like and will return null if the nth least requested exceeds the number of distinct values. The nleast function that I wrote uses the str2tbl function by Tom Kyte. I have included a demonstration of its usage below. The value returned for the 1st least is the same as that returned by the least function.
This should have been posted on the SQL and PL/SQL discussion group of these forums, rather than the general database. I also posted the same response in the SQL discussion group of the Orafaq forums.

Using a custom itemrenderer in datagrid to update value in the same row but different column/cell
Here's what I have so far. I have one datagrid (dg1) with enable drag and another datagrid (dg2) with dropenabled. Column3 (col3) of dg2 also has a custom intemrenderer that's just a hslider.
When an item from dg1 is dropped on dg2, a custom popup appears that asks you to use the slider in the popup to set a stress level. Click ok and dg2 is populated with dg1's item as well as the value you selected from the popup window. I was also setting a sliderTemp variable that was bound to the itemrender slider to set it but that's obviously causing issues as well where all the itemrenderer sliders will change to the latest value and I don't want that.
What is needed from this setup is when you click ok from the popup window, the value you choose from the slider goes into dg2 (that's working) AND the intemrenderer slider needs to be set to that value as well. Then, if you used the intemrenderer slider you can change the numeric value in the adjacent column (col2). I just dont know how to hook up the itemrenderer slider to correspond with that numeric value (thatds be in col2 on that row);

Sequential Count of rows in a Column
Hi,
In a query, I have a table defined with the relevant detail required by the business. I need to insert a count into the first column so it identifies a unique number. e.g. row 1 = 1, row 2 = 2 etc.
How can this be done?Further to this question, to clarify diagramatically what I'm trying to achieve is as follows:
Row Counter | Header 2 | Header 3 | Header 4
1 data data data
2 data data data
3 data data data
4 data data data
I need to add the first column into my report but I don't know how to acheive this.
Can anyone assist? -
Need a rolling count of rows from table using just SQL
Oracle 11gR2
RHEL 6.4
Given the following table data:
EMPLOYEE HIRE_DATE TERM_DATE DEPT
John Doe 01/01/13 101
Jane Smith 01/05/13 102
Bob Jones 02/04/13 04/22/13 102
Jenny Boo 03/12/13 03/31/13 103
Joe Schmoe 03/24/13 102
Bill Max 04/23/13 103
Jill Clay 04/24/13 103
Joe Boom 05/11/13 102
I want to return the number of employees that are still employed for each month so long as they were hired anytime in that month and irregardless if they were terminated later that month (i.e only the month concerns me). So I would be expecting
MONTH EMPLOYEES
Jan 2
Feb 3
Mar 5
Apr 6 (Jenny Boo has been terminated)
May 6 (Jenny Boo and Bob Jones have been terminated)
I know there are some bright people out there that are SQL experts but I am not one of them. If there is a way to do this in just SQL I would like to see it.Assuming you want count just for months where someone was hired or terminated:
with t as (
select trunc(hire_date,'mm') dt,
1 weight
from emp1
union all
select last_day(term_date) + 1 dt,
-1 weight
from emp1
where term_date is not null
select to_char(dt,'FMMonth, YYYY') month,
sum(sum(weight)) over(order by dt) employees
from t
group by dt
order by dt
MONTH EMPLOYEES
January, 2013 2
February, 2013 3
March, 2013 5
April, 2013 6
May, 2013 6
SQL>
If you want all months within given range:
with r as (
select date '2013-03-01' from_dt,
date '2013-12-01' to_dt
from dual
t as (
select trunc(hire_date,'mm') dt,
1 weight,
from_dt
from emp1,
r
where hire_date <= last_day(to_dt)
union all
select last_day(term_date) + 1 dt,
-1 weight,
from_dt
from emp1,
r
where last_day(term_date) + 1 <= to_dt
union all
select add_months(from_dt,level - 1) dt,
0 weight,
from_dt
from r
connect by add_months(from_dt,level - 1) <= to_dt
s as (
select dt,
sum(sum(weight)) over(order by dt) employees,
from_dt
from t
group by dt,
from_dt
select to_char(dt,'FMMonth, YYYY') month,
employees
from s
where dt >= from_dt
order by dt
MONTH EMPLOYEES
March, 2013 5
April, 2013 6
May, 2013 6
June, 2013 6
July, 2013 6
August, 2013 6
September, 2013 6
October, 2013 6
November, 2013 6
December, 2013 6
