Selecting from a column based on the id

Hello All,
Is there a way to update a table based on the column id?
Example: I have a table where column 2 is an accumulated dollar amount. Each row of the column is a lease.
I need to update column 3 with $$ that i get from my cursor say x. Then column 4 is needs to be updated with
amount in column 2+ amount in column3.
Again column 5 needs to be update with the next $$amount that i get from my cursor x. Now column 6 needs to
be updated with amount in value in column 4 and column5...so on and so forth.
I can get the column names from the dba_tab_columns. However I don't know if those column names can be used in the
update/insert statements to populate the table.
Thanks,
Chiru

Hi,
I'm not sure I understand the problem.
You can use column names in a INSERT and UPDATE statements. for example:
UPDATE my_table
SET column_3 = x
, column_4 = column_2 + column_3;When you use a column name to the right of the "=" sign, it always refers to the old value.
In the 3rd line of the example above, column_4 is set to the old value of column_2 plus the old value of column_3, not the new value (x) that was given to column_3 in the 2nd line.
If you have a problem, post
(1) a little sample data (three ros, maybe) before UPDATE, and
(2) what those same rows should be after the UPDATE,
(3) explanation, (such as "I want to add the parameter :amt to column_5 and subtract :amt from column_6.")

Is this possible?

Hi serenace,
To achieve your requirement, you can reference the below.
DECLARE @Tbl TABLE(ctrlno INT,jobid INT,docdate DATE,work1 INT,work2 INT,work3 INT);
INSERT INTO @Tbl VALUES(1,7,'2/12/2014',20,10,NULL);
INSERT INTO @Tbl VALUES(2,7,'2/22/2014',35,NULL,15);
INSERT INTO @Tbl VALUES(3,7,'2/28/2014',NULL,NULL,12);
INSERT INTO @Tbl VALUES(4,8,'1/17/2014',15,13,23);
INSERT INTO @Tbl VALUES(4,8,'2/17/2014',15,NULL,NULL);
INSERT INTO @Tbl VALUES(4,8,'3/17/2014',NULL,16,NULL);
;WITH cte AS(
SELECT jobid,docdate,attr,value FROM
@Tbl
UNPIVOT
(value FOR attr IN(work1,work2,work3)) AS UT
cte2 AS(
SELECT jobid,attr,value , ROW_NUMBER() OVER(PARTITION BY jobid,attr ORDER BY docdate DESC) AS rn
from cte
SELECT jobid,ISNULL([work1],0) [work1],ISNULL([work2],0) [work2],ISNULL([work3],0) [work3] FROM
cte2
PIVOT
(SUM(value) FOR attr IN([work1],[work2],[work3])) AS PT
WHERE rn=1

I want to retrieve data from p0001-PLANS based on the below condition,

Hi,
I want to retrieve data from p0001-PLANS
based on the below condition
select stext from hrp1000 where plvar = '01' and otype = 'S' and objid = p0001-plans and begda GE pn-begda and endda LE pn-endda.
Thanks,
Rama.

Hi
Based on the Query you have specified thoise are stoerdin an Internal table- then
select stext from hrp1000 into table t_hrp where plvar = '01' and otype = 'S' and objid = p0001-plans and begda GE pn-begda and endda LE pn-endda.
The check table for this PLANS is T528B .
if t_hrp[] is not intitial.
select * from t528B intot table t_528 where plans eq t_hrp-plans.
endif.
Now you can get the PLANS data.
Refer to the Text tbale for PLANS - T528T
To get the TEXTS -
if t_hrp[] is not initial.
select * from T528T into table t_528T where plans eq t_hrp-plans.
endif.

When I import a text file(comma separated )into a numbers spread sheet all the data goes into one column. Why does the text not go into separate columns based on the commas.

When I import a text file(comma separated) into a numbers spreadsheet all the data goes into one column instead of individual columns based on the comma separators. Excel allows you to do this during the import.. Is there a way to accomplish this in numbers without opening it in Excel and the importing into Numbers.

Your user info says iPad. This is the OS X Numbers forum. Assuming you are using OS X… Be sure the file is named with a .csv suffix.
(I don't have an iPad, so I don't know the iOS answer.)

How can i dynamically select columns based on the input parameter?

I have an input parameter which takes single numeric value.
Based on this value i have to dynamically select table-columns .
For eg: if i have following fields in my table :
SEM_1
SEM_2
SEM_3 and SEM_4.
And if i give numeric input as 2 , then i have to select "SEM_2" column only.
if the input is 3 then i have to select "SEM_3" only and leave the rest of the columns.
how do i achieve this dynamic feature in the "Select ..... From...... table...." statement in the ABAP??

Hi,
you should try something like this.
TYPES: cond(72) TYPE c.
data: condtab TYPE TABLE OF cond,
condw type cond.
data: lv_field(30) type c value 'SEM_'.
write p_num to lv_field+4(1).
condw = lv_field.
append condw to condtab.
SELECT (CONDTAB) FROM table INTO.....

How can I select and delete rows based on the value in one column?

I searched through the discussion board, and found a thread on deleting blank rows, but not sure how to modify it to work with my issue.
I have put together a rather complicated spreadsheet for designing control systems, it calculates parts needed based on check boxes selected in a second spreadsheet.
Since not all systems require all parts there are many rows that have a 0 quantity value, I would like to select these rows and delete them once I have gone through the design phase (checking off required features on a separate sheet).
I like the way the other thread I found will gather all the blank rows at the bottom without changing the order of the rows with data in them.
I don't understand exactly how the formula in the other thread works well enough to modify it to look for a certain column.
I hope I made myself clear enough here, to recap, I would like to sort the rows based on a zero value in one (quantity) column, move them (the zero quantity rows) to the bottom of the sheet, and then delete the rows with a zero quantity (I can delete them manually, but would like to automate the sorting part).
Thanks for any help anyone can provide here.
Danny

I apologize but, as far as I know, Numbers wasn't designed by Ian Flemming.
There is no "this column will be auto-destructing after two minutes"
You will have to use your fingers to delete it.
I wish to add a last comment :

How to exit from SQL*Plus based on the return value of a SQL select stment?

Hi
I have a SQL script executed from SQL*Plus. I would like to know if SQL*Plus
supports any kind of branching or exiting from script execution based on a
returned value of a SQL select statement. I am on 9i.
Regards,
Tamas Szecsy

in sqlplus, you have whenever
ex:
whenever sqlerror exit failure
insert into ...
-- if this fails, then you will be out
insert into ...
-- if this fails, then you will be out
whenever sqlerror continue
insert into ...
-- if this fails, this continues
insert into ...and you have PL/SQL
declare x number;
begin
select count(*) into x from emp;
if (x=14) then null; end if;
end;
/note that you can mix those in some case
-- exit if there is no row in emp
whenever sqlerror exit 1
var dummy number
exec select count(*) into :dummy from emp having count(*)!=0

Select from different tables based on value

Hi Forum,
I'm stuggling with a problem:
In a table, I have two columns, pref_type and pref_value. Column pref_type stores a number value that is linked to a preference type, whereas column pref_value stores the value of that preference.
Unfortunately, the data model is such that per preference type a different tables needs to be used, so for example, if
pref_type = 1, table to query is A, whereas if
pref_type = 2, table to query is B.
I now want to write a query that resolves the preferences, ie it should branch to the respective table based on pref_type and search for pref_value and deliver back a different column of that respective table.
My first approach was like that:
select decode (pref_value, 1, (select result from A where pref_value = ???),
2, (select result from B where pref_value = ???)
where the three ??? depict the problem I'm having, as Oracle doesn't allow me to have a harmonized subquery here.
How do I achieve this?
Thanks for any help,
J. Sieben

I believe this is what you are trying to get at:
SELECT DECODE(m.pref_type, 1, (SELECT result FROM a
                               WHERE a.pref_value = m.pref_value),
                           2, (SELECT result FROM b
                               WHERE b.pref_value = m.pref_value)
FROM my_table mAlthough, if the tables are large, that might be pretty slow. Better than an outer join, but one of those correlated queries is going to be run for each row in my_table. You could lso try something like:
SELECT m.pref_type, r.result
FROM my_table m,
     (SELECT 'A' tbl, pref_value, result
      FROM a
      UNION ALL
      SELECT 'B', pref_value, result
      FROM b) r
WHERE DECODE(m.pref_type, 1, 'A', 'B') = r.tbl and
      m.pref_value = r.pref_valueHTH

Inserting new columns based on the condition!

Hi guys,
I have a very simple query like the following…
SELECT table2.column_code2,
table2.column_description2,
table2.column_code1,
table1.column_description1
FROM database_001.table2 table1 LFET OUTER JOIN database_001.table2 table1 on (table2.column_code1 = table1.column_code1)
From this query, its returning me a result set of something like below:
column_code1 column_description1 column_code2 column_description2
RO1 BOOK RL1
PDF/ECOPY
RO2 PAPER RL2
CONFERENCE
RO5 JOURNAL
RL11 OTHER
Now, on the above query I want to insert three extra columns with the name (status, location and contact) where the results in the extra three columns would be based on the conditions I want to define in the query based on the above results…
Something for example (sorry, I am not trying to write a condition: my question is how to write it),
if column_code1 = RO1 and column_description2 = PDF/ECOPY on status column it should return a value ‘ONLINE’ & on location column it should return ‘WEB’ and on contact column it should write ‘BOB’.
Also,
if column_code1 = RO5 and column_description1 = JOURNAL on status column it should return a value ‘ON PRESS FOR PRINT’ & on location column it should return ‘S.R STREET, LONDON’ and on contact column it should write
‘SMITH’ like below result…so the final output should be the top four columns and the extra three columns…I hope someone can help me into this…thanks a lot…
status location
contact
ONLINE WEB
BOB
ON PRESS FOR PRINT S.R STREET, LONDON SMITH

Hi artistdigital,
you can use case statment for same in sql server. MSDN link - > http://technet.microsoft.com/en-us/library/ms181765.aspx
Try code like this:
SELECT table2.column_code2,
table2.column_description2,
table2.column_code1,
table1.column_description1,
case when column_code1 = 'RO1' and column_description2 = 'PDF/ECOPY' then 'ONLINE'
when column_code1 = 'RO5' and column_description1 = 'PDF/ECOPY' then 'ON PRESS FOR PRINT'
end as [status],
case when column_code1 = 'RO1' and column_description2 = 'PDF/ECOPY' then 'WEB'
when column_code1 = 'RO5' and column_description1 = 'PDF/ECOPY' then 'S.R STREET, LONDON'
end as [Location],
case when column_code1 = 'RO1' and column_description2 = 'PDF/ECOPY' then 'BOB'
when column_code1 = 'RO5' and column_description1 = 'PDF/ECOPY' then 'SMITH'
end as [contact]
FROM table2

Sort a table with two columns based on the first

I have a powershell table with the columns 'Used Perc' and 'ID'.
This was formed from the following
$a = @{Expression={[System.Math]::Round(($_.nUsed_Avg/$_.nSize)*100,1)};Label="Used Perc";width=25}, @{Expression={$_.nStatisticalDiskIdentificationID};Label="ID";width=15}
$GLOBAL:CSV2 = Import-CSV $STATDISKOUT | Format-Table $a
Before this, the file $STATDISKOUT had the columns 'nUsed_Avg', 'nSize', and 'nStatisticalIdentificationID'.
My question is, how would I sort the new table based on 'Used Perc' but keeping the corresponding 'ID' column lined up to the right value?

We use a select statement to reorder columns and recalculate, The formatters just go at the end to adjust the display.
Import-Csv <file> | select <column order format> | Format-Table
or you can do it in the table:
Import-Csv <file | Format-Table -Properties ,f1.,f2.,,f3....Here is how to inset a sort inline:
$a=@{
L='ID';
E={$_.nStatisticalDiskIdentificationID};
L='Used Perc';
E={[System.Math]::Round(($_.nUsed_Avg/$_.nSize)*100,1)}
Import-CSV $STATDISKOUT | Select $a | Sort 'Used Perc' | Format-Table -Auto

Calculated column based on the value of a prompt

Hi all
I created a page prompt for the user than he can choose the years period: for example Year: between 2009 and 2015
In the report I have one of the measures that and I only want to display for the year 2009.I don't want to sum from 2009 till 2015
currently It calculating the sum from 2009 till 2015 and I only want it for the begining year of the period that the user selects in the prompt
How can I do that??
Regards

try to de-attach the prompt from your SA i.e. once you choose a column month to be in the prompt edit the formula and enter e.g. 'Start month'; then select the same column again and edit the formula and enter e.g. 'End month'; for each of the columns set the operator to equal; add presentation variables for both columns; then in the report use these variables in the filter for the remaining measures and for the one in question use the filter using; see if this would work

If you would have posted the XML path with nodes, I can provide the SQL with full path but try to use the below SQL changing their SQL path and root
select extractValue(object_value, '/<XMLPath>/C24')
as Id
from invoicexml_tbl;
If you want to use in WHERE clause, use existsnode method
select * from invoicexml_tbl
where existsNode(object_value, '/<XML Path>/row[c24="SA0010001"]') = 1;
