Split single row in multiple rows based on date range

I need sql script that can split single row in multiple rows based on start date and end date column in table.
Thank you

I agree to your suggestion of having a dates table permanently in the database. Thats how we also do for most of our projects as well
But in most projects the ownership of table creation etc lies with the client as they will be the DBAs and will be design approval authorities. What I've seen is the fact that though
many of them are in favour of having calendar table they dont generally prefer having a permanent table for numbers in the db. The best that they would agree is for creating a UDF which will have
tally table functionality built into it based on a number range and can be used in cases where we need to multiply records as above.
Wherever we have the freedom of doing design then I would also prefer creating it as a permanent table with required indexes as you suggested.
>> many of them are in favour of having calendar table they dont generally prefer having a permanent table
Those people do not understand about database and are not DBAs :-)
It is our job to tell them what is right or wrong.
** This is a real story! I had a client several years back, who was the CEO of a software company.
He use the query:
select * from table_name
In order to get the last ID!
The table_name was actually a view that took data from several tables, and the main table that he wanted to get the ID included several string columns, with lot of data!
he actually pulled all this data to the application, just to get the lat ID in a specific table!
It is our job as Consultants or DBAs to fix's his misunderstanding :-)

Split single row into multiple rows containing time periods

Hi,
I have a table with rows like this:
id, intime, outtime
1, 2010-01-01 00:10, 2010-01-3 20:00
I would like to split this row into multiple rows, 1 for each 24hr period in the record.
i.e. The above should translate into:
id, starttime, endtime, period
1, 2010-01-01 00:10, 2010-01-02 00:10, 1
1, 2010-01-02 00:10, 2010-01-03 00:10, 2
1, 2010-01-03 00:10, 2010-01-03 20:00, 3
The first starttime should be the intime and the last endtime should be the outtime.
Is there a way to do this without hard-coding the 24hr periods?
Thanks,

Thanks for all the feedback, Dan.
It appears that the respective solutions provided will give you: a) different resultsets and b) different performance.
Regarding your 'truly desired resultset' you haven't answered all questions from my previous post (there are differences in the provided examples), but anyway:
I found that using CEIL or ROUND makes quite a difference, using my 'simple 3 record testset' (30 records vs. 66 records got initially returned, that's less than half of the original). That's quite a difference. However, I must call it a day (since it's almost midnight) for now, so there's room for more optimizement and I haven't thoroughly tested.
But this might hopefully make a difference performancewise when compared to my previous 'dreaded example':
SQL> drop table t;
Table dropped.
SQL> create table t as
2 select 1 id, to_date('2010-01-01 00:10', 'yyyy-mm-dd hh24:mi') intime, to_date('2010-01-03 20:00', 'yyyy-mm-dd hh24:mi') outtime from dual union all
3 select 2 id, to_date('2010-02-01 00:10', 'yyyy-mm-dd hh24:mi') intime, to_date('2010-02-05 20:00', 'yyyy-mm-dd hh24:mi') outtime from dual union all

How can i select some row from multiple row in the same group of data

I want to select some row from multiple row in the same group of data.
ColumnA
Column B
1 OK
1 NG
2 NG
2 NG
3 OK
3 OK
I want the row of group of
ColumnA if ColumnB contain even 'NG'
row , select only one row which Column B = 'NG'
the result i want =
ColumnA Column B
1 NG
2 NG
3 OK
Thank you

That's some awful explanation, but I think this is what you were driving at:
DECLARE @forumTable TABLE (a INT, b CHAR(2))
INSERT INTO @forumTable (a, b)
VALUES
(1, 'OK'),(1, 'NG'),
(2, 'NG'),(2, 'NG'),
(3, 'OK'),(3, 'OK')
SELECT f.a, MIN(COALESCE(f2.b,f.b)) AS b
FROM @forumTable f
LEFT OUTER JOIN @forumTable f2
ON f.a = f2.a
AND f.b <> f2.b
GROUP BY f.a

Single row to multiple row

Hi All,
I need a help in a query to convert a row to multiple row.
I have two tables
TableA
ID1 attribute1_Name attribute1_code
ID1 attribute2_Name attribute2_code
ID2 attribute1_Name attribute1_code
ID2 attribute2_Name attribute2_code
ID2 attribute3_Name attribute3_code
ID4 attribute1_Name attribute1_code
ID4 attribute2_Name attribute2_code
ID4 attribute3_Name attribute3_code
ID4 attribute4_Name attribute4_code
attribute name and attribute code can vary 1 to n for different id
let's one ID has maximum no of codes 20 , then TableB will have columns like (EMP ID attribuute_code1 attribuute_code2 .... attribuute_code20)
in TableB all the columns named attribuute_code1 ..attribuute_code20 will have value for those attribute
TableB ( )
Column EMP ID attribuute_code1 attribuute_code2 attribuute_code3 attribuute_code4
EMP1 ID1 attribute1_value attribute2_value null null
EMP2 ID1 attribute1_value attribute2_value attribute3_value null
EMP3 ID2 attribute1_value attribute2_value attribute3_value attribute4_value
EMP and ID is composite p.k
My resulting table should have
EMP1 ID1 attribute1_value
EMP1 ID1 attribute2_value
EMP2 ID1 attribute1_value
EMP2 ID1 attribute2_value
EMP2 ID1 attribute3_value
EMP3 ID2 attribute1_value
EMP3 ID2 attribute2_value
EMP3 ID2 attribute3_value
EMP3 ID2 attribute4_value
Thanks in advance ...

How do I divide a list in one cell into multiple rows?

I have copied lists of data from a website - some lists pasted as I want them (in individual rows), but others pasted the list in one row. Is there an easy way to split a list in a single cell into multiple cells so ultimately I can sort all the rows? I've tried "split the selected cells into rows" in the inspector, but it's not working... seems like it's creating another column instead (?). Any help would be amazing.

K,
I find that Pages has the friendliest Find and Replace dialog, so when I need to swap around the delimiters I go straight to Pages and do the fixes there. Replace whatever is there between columns in the original content with Tab characters and replace whatever is there now for delimiting the rows with the Return character. Since it's sometimes difficult to tell what has been used, just copy it from the content and Paste into the Find field. Choose the Tab or Return character from the Replace drop down menu.
When you have it all fixed up, then paste into Numbers.

Splitting a message with multiple rows from the JDBC Adapter

Hi,
I'd like to split the resultset message with multiple row elements and process each row separately..
Does someone have this experience?
Thanx, Peter

Hi Chandrasekhar,
I tried to follow your advise, but I'm not able to complete the process correctly.
Let me explain my process:
First - output from the JDBC adapter goes into the first receive step. Of course, there are multiple ROW elements. (Should be marked the ingoing message marked in the container as Multiline??)
The next should be the transformation:
format of the source message is like
<message>
<row>
<column>w</column>
</row>
<row>
<column>w</column>
</row>
</message>
In the message I have the ROW element as 0..unbounded
and <column> element exactly 1
This message should be mapped to multiple messages of the format:
<message>
<value>w</value>
</message>
How should be the mapping be done?
Is it N:1 or 1:N (because in another thread there was an 1:N mapping advised)
Then (as you say) should follow the Block step:
Which message (container element) should be marked as Multiline? And what does it mean: Current Message?
Can you give me some advise, when and how to use the multiline mark?
Thanx a lot, Peter

SSIS + split 1 row in multiple rows based on multiple columns

Hi all,
I have a flat file
Shop ID Check 1 Check 2 Check 3
500 OK
OK NOK
I want to transform this to staging as 3 rows
Shop ID Check number
Result
500 1
OK
500 2
OK
500 3
NOK
Anyone can tell me how to tackle this?

I basically have a table that has the columns I specified
Shop Check 1
Check 2 Check 3
500 OK
OK NOK
I now want to actually have them loaded in another table where I have multiple rows for each shop.
Shop Check
Result
500
1 ok
500 2
ok
500 3
nok
So basically I want to go from a column view to a row view. Is this possible?
In other words, I do see multiple rows for each shop ID which is awesome! But I would like to have instead of the result that number of the check. (1,2,3) with the result next to it :)
500 OK
500 OK
500 NOK

hi Akhilesh,
Use tree table for your requirement.

Single Update command to update multiple rows with multiple rows

Hi Gurus!
Can I update table A with a result set of table b (multiple rows returns) where a.c1 = b.c1
regards,
SH

As Joel mentioned this update will update all rows in a table based on another one:
update tableA set seq_no = (select seqno from tableB where tableA.ID = tableB.ID)
Also, any rows that don't match the select criteria will get updated to null. This could be very bad depending on what you want to do.
To update a subset of tableA with data from tableB:
update tableA set seq_no = (select seqno from tableB where tableA.ID = tableB.ID)
where exists (select 1 from tableB where tableA.ID = tableB.ID)

During import, how to auto split one project into multiple albums based on date?

I believe I've done enough aperture reserach to get all my terminology right, so here goes...
I've created a file structure within the aperture inspector the the tune of:
Year [folder], Type of event (Occasion, special occasion, holiday, vacation) [folder], Project (Wedding), Album (i.e. Day 1, Day 2 or Pre wedding week, event, honeymoon).
I also have entire months with 7 or 8 pictures each day, that are of the same type/project (random dog pictures) but are distinctly different days (albums - day in park, in bed at night, watching movie).
My question is, can I import one project with multiple albums already created based on the date they're taken. As I can see it, all I can do is split individual projects automatically by date. But what if one project is over one month, but has multiple distinct days that would be ideal for albums? One more example. We did a trip to San Fran. One day was touring the city, one day was a concert, another day was touring the city. All one project, but 3 different albums (in my mind). I had to import as one project, then separately go in and make albums. I would like that done automatically.
My suspicion is that I can not natively do this within aperture, and that I would need something called an "applescript." I haven't done any reserach into that area, so if that's the case and you know where I can find a script that would do this, I'd appreciate the help.
Sorry for the wordiness, just wanted to be clear. Thanks for any and all help!

Hi,
You need to create a new requirement in tcode VOFM for that, together with your ABAP consultant. This requirement will be used in copy contol.

1 row into multiple rows

I have a table time_entries
create table time_entries
(employee_id integer,
start_date date,
end_date date,
CONSTRAINT pk_time_entries PRIMARY KEY (employee_id, start_date))Suppose I have one row in this table (dates in yyyy-mm-dd format):
employee_id, start_date, end_date
1, 2012-08-27, 2012-09-02
As you can see the difference between the dates is 7 days. I want to write a query so that each day has its own row, i.e. I want to write a query which translates the above 1 row into 7 rows. This is the result set I want:
employee_id, start_date, end_date
1, 2012-08-27, 2012-08-27
1, 2012-08-28, 2012-08-28
1, 2012-08-29, 2012-08-29
1, 2012-08-30, 2012-08-30
1, 2012-08-31, 2012-08-31
1, 2012-09-01, 2012-09-01
1, 2012-09-02, 2012-09-02
Is it possible to do it in one select statement?
