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?

Thanks in advance!You should be doing this in the client on not in the DB. Use the reporting tool that you use to do this.
For example if you are in SQL Plus you can use the BREAK command.

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':

Table dropped.
SQL> create table t as

Convert one record row into multiple rows

Hi,
I have small requirement.I have selected one data base record into an internal table.Now internal table has 1 record i.e 1 row(ex: 10 columns). Now i will convert this single row record into multiple records i.e 10 rows( 10 columns wil; be converted into 10 rows). How i will convert this. Please give me any idea on this.

Convert 1 row into multiple rows

Guys - I have a table with 6 columns and it looks like this:
1 2 3 4 5 6
1 XX Y A Z ABC
2 XX P AB CN CAB
Now I want my output to be:
1 2 3 4 5 6
1 XX Y AAA AAB ABC
2 XX Y AAC AAD ABC
3 XX Y AAE AAF ABC......
26 XX Y AAY AAZ ABC
27 XX P ABA ABB CAB
28 XX P ABC ABD CAB
9999 XX P CNY CNZ CAB
I am trying to do this in SQL , but without much luck. I can always do it with pl-sql but I want to keep that as my last option.
Please, let me know if I need to explain this further...
Thanks..

1. Its not that I cannot do with pl/sql, but would like to try this with pure sql than pl / sql, thats what I meant
2. for length( col4 and col5 ), its actually length(col4) =3 and length(col5) = 3, sorry if you miss understood it
3. You are making up your data for all the possible combinations you might have i the future, thats why you are adding 'A' till 'Z' to each and every row...
so for example if a row has
col1 col4 col5 col6
1 ZZX ZZZ john
Now I need to make this row as:
col1 col4 col5 col6
1 ZZX ZZY john
2 ZZZ ZZZ john
So in the future if john is replaced by jack...then all I have to do it update these 2 rows col6 to 'jack' instead of 'john'.
Now the col1 which is the primary key for my new table actually goes into another table as ID field (in my fact as a dimension key)....so I dont have to update both the tables rather I can live with just updating 1 table...
Let me know if you need further explanation...

Spliting rows into multiple rows based on time interval

Hi experts need your help for framing query for the below scenarios
Scenario 1
Query should check for priority record(25), if the start_date and end_date of that priority record is the max in that group, records will not have any split.
output will be the same.
DC Store St Date End date Priority
955 3 1/1/2010 12/31/9999 25
966 3 4/5/2011 10/10/2011 50
977 3 10/12/2011 12/12/2012 100
output
DC store St Date End date Priority Rank
955 3           1/1/2010 12/31/9999 25 1
966 3           4/5/2011 10/10/2011 50 2
977 3           10/12/2011 12/12/2012 100 3
Scenario 2
If priority record is not covering the max range, then split the records as shown below,
1. during the time period 1/1/2011 & 4/30/2011 there were no other DC for that store so rank would be 1
2. the next range would be 5/1/2011 to 6/29/2011 we have 2 records in service so the record with low priortiy would be ranked 1 and second priority would be ranked 2
3. similarly, for 6/30/2011 to 10/1/2011 we have 3 records in service and it will be ranked accordingly on the priority.
DC Store St Date End date Priority
966 3 6/30/2011 10/1/2011 25
955 3 5/1/2011 11/30/2011 50
977 3 1/1/2011 12/31/2011 100
output
DC store St Date End date Priority Rank
977 3 1/1/2011 4/30/2011 100 1
955 3 5/1/2011 6/29/2011 50 1
977 3 5/1/2011 6/29/2011 100 2
966 3 6/30/2011 10/1/2011 25 1
955 3 6/30/2011 10/1/2011 50 2
977 3 6/30/2011 10/1/2011 100 3
955 3 10/2/2011 11/30/2011 50 1
977 3 10/2/2011 11/30/2011 100 2
977 3 12/1/2011 12/31/2011 100 1
Scenario 3
This works similar to scenario 2
DC Store St Date End date Priority
966 3 2/1/2011 12/31/2011 25
955 3 1/1/2011 12/31/2012 50
977 3 5/1/2011 06/31/2011 100
output
DC store St Date End date Priority Rank
955 3 1/1/2011 1/31/2011 50 1
966 3 2/1/2011 12/31/2011 25 1
955 3 2/1/2011 12/31/2011 50 2
977 3 5/1/2011 6/30/2011 100 3
955 3 1/1/2012 12/31/2012 50 1
Note: the number of rows coming in input will be dynamic and there are possibilities for the date ranges to overlap.

Hi,
Sorry, your requirement are unclear.
What role do dc, store and priority play in this problem? Prioriry obviously has something to do with how rows are split. Why is priority=25 special? Does the number 25 have some speciakl meaning, or does it just happen to be the lowest value of priority? Can 2 (or more) rows have the same priority? if so, can their dates overlap? Include examples in your sample data and results.
I think you want something like this:
WITH     all_dates     AS
     SELECT     st_date          AS a_date
     ,     priority
     FROM     table_x
    UNION ALL
     SELECT     end_date + 1     AS a_date
     ,     priority
     FROM     table_x
,     got_break_date     AS
     SELECT       a_date
     ,       LEAD (a_date) OVER (ORDER BY a_date)     AS next_date
     ,       MIN (priority)                     AS min_priority
     FROM       all_dates
     GROUP BY a_date
,     paired_data     AS
     SELECT       x.*
     ,       b.*
     ,       GREATEST ( x.st_date
                       , b.a_date
                  )          AS s_date
     ,       LEAST ( x.end_date
                   , b.next_date
               )          AS e_date
     ,       RANK () OVER ( PARTITION BY GREATEST (x.st_date, b.a_date)
                                   ORDER BY      x.priority
                      )        AS rnk
     FROM     table_x          x
     JOIN     got_break_date     b ON   b.a_date     >= x.st_date
                       AND     b.a_date         < x.end_date
                       AND     b.min_priority <= x.priority
SELECT       dc
,       store
,       s_date          AS st_date
,       e_date - CASE
                   WHEN rnk     = 1
                 AND   end_date     = e_date
                 THEN 0
                 ELSE 1
               END          AS end_date
,       priority
,       rnk
FROM       paired_data
ORDER BY s_date
,            priority
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and the results you want from that data, formatted, between \ tags. See the froum FAQ {message:id=9360002}
Point out where the results of the query above are wrong, and explain, using specific examples, how you get those results from the given data in those places.
Always say what version of Oracle you're using.

Splitting comma seperated column data into multiple rows

Hi Gurus,
Please help me for solving below scenario. I have multiple value in single column with comma seperated values and my requirement is load that data into multiple rows.
Below is the example:
Source Data:
Product         Size                                 Stock
ABC              X,XL,XXL,M,L,S                 1,2,3,4,5,6
Target Data:
Product         Size                                 Stock
ABC              X                                     1
ABC              XL                                   2
ABC              XXL                                 3
ABC              M                                    4
ABC              L                                      5
ABC             S                                        6
Which transformation we need to use for getting this output?
Thanks in advance !

Hello,
Do you need to do this tranformation through OWB mapping only? And can you please tell what type of source you are using? Is it a flat file or a table?
Thanks

Easy Question: How to split concatenated string into multiple rows?

Hi folks,
this might be an easy question.
How can I split a concatenated string into multiple rows using SQL query?
INPUT:
select 'AAA,BBB,CC,DDDD' as data from dualDelimiter = ','
Expected output:
data
AAA
BBB
CCC
DDDDI'm looking for something kind of "an opposite for 'sys_connect_by_path'" function.
Thanks,
Tomas

Here is the SUBSTR/INSTR version of the solution:
SQL> WITH test_data AS
2 (
3          SELECT ',' || 'AAA,BBB,CC,DDDD' || ',' AS DATA FROM DUAL
4 )
5 SELECT SUBSTR
6          (
7                  DATA
8          ,       INSTR
9                  (
10                          DATA
11                  ,       ','
12                  ,       1
13                  ,       LEVEL
14                  ) + 1
15          ,       INSTR
16                  (
17                          DATA
18                  ,       ','
19                  ,       1
20                  ,       LEVEL + 1
21                  ) -
22                  INSTR
23                  (
24                          DATA
25                  ,       ','
26                  ,       1
27                  ,       LEVEL
28                  ) - 1
29          )       AS NEW_STRING

Merge multiple rows into single row (but multiple columns)

How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5
23 asdc 1 Location USA NM ABQ Four Seasons 87106
23 asdc 1 Stats 2300 91.7 8.2 85432
23 asdc 1 Audit 1996 June 17 1200
65 affc 2 Location USA TX AUS Hilton 92305
65 affc 2 Stats 5510 42.7 46 9999
65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type.
For example for Information_Type=Location
Attribute_1 means Country
Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population
Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime
23 asdc 1 USA NM ABQ FourSeasons 87106 2300 91.7 46 85432 1996 June 17 1200

Hi,
That's called Pivoting . The forum FAQ has a section on this subject: {message:id=9360005}
I hope this answers your question.
If not, post your best attempt, along with a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data. (You did post the results you wanted, but they're very hard to read because they're not formatted. Use \ tags, as described in the forum FAQ, below.)
Explain, using specific examples, how you get the results you want from the data given.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0). This is always important, but especially so with pivots.
See the forum FAQ {message:id=9360002}

Split one row into multiple columns

Hi,
Data in one CLOB column in a table storing with delimiter, ##~~##. Ex. ##~~##abc##~~##defgh##~~##ijklm##~~##nopqr (data starts with delimiter). Please help me to split the data into multiple rows like below and it should be in the same order.
abc
defgh
ijklm
nopqr
I am using Oracle 11g.
Thanks.

Thanks Hoek for your response. Before posting my question in the forum, I tried similar query. It is working with one character as delimiter.
with test as (select 'ABC,DEF,GHI,JKL,MNO' str from dual )
select regexp_substr (str, '[^,]+', 1, rownum) split
from test
connect by level <= length (regexp_replace (str, '[^,]+')) + 1;
Above query is giving correct result by fetching 5 rows. I have modified the query like below...
with test as (select 'ABC,,,DEF,,,GHI,,,JKL,,,MNO' str from dual )
select regexp_substr (str, '[^,,,]+', 1, rownum) split
from test
connect by level <= length (regexp_replace (str, '[^,,,]+')) + 1;
Above query resulting 13 rows and last 8 rows are nulls. Number of null rows are increasing, if I increase number of characters in delimiter. Could you please tell me how to avoid those null rows.
Thanks.

Cats ESS view - into multiple rows when we release times or refresh them

Dear ALL,
We are using the record working times and when we enter the data for the week for 5 days each with 8 hours a day in one row in portal. Once we refresh or review that page it is resulting into multiple rows, like for 5 days five rows each row containing an entry for each day. how can we avoid this, we want all entries maintained into one row only.
Help is appreciated.
Thanks and Regs,
Raj

Please - immediate help needed parsing csv values into multiple rows

Hello, we have a very immediate need to be able to parse out a field of comma separated values into individual rows. The following is an example written in SQL Server syntax which does not work in Oracle.
The tricky part is that each ROUTES can be a different length, and each CSV can have a different number of routes in it.
Here is an example of the table ("Quotes") of CSV values I want to normalize:
TPNUMBER ROUTES
1001 1, 56W, 18
1002 2, 16, 186, 28
Here is an example of what I need it to look like:
TPNUMBER ROUTES
1001 1
1001 56W
1001 18
1002 2
1002 16
1002 186
1002 28
Here is the "Tally" table for the query below:
ID
1
2
3
4
5
6
7
And finally, here is the query which parses CSV values into multiple rows but which does not work in Oralce:
SELECT TPNUMBER,
NullIf(SubString(',' + ROUTES + ',' , ID , CharIndex(',' , ',' + ROUTES + ',' , ID) - ID) , '') AS ONEROUTE
FROM Tally, Quotes
WHERE ID <= Len(',' + ROUTES + ',') AND SubString(',' + Phrase + ',' , ID - 1, 1) = ','
AND CharIndex(',' , ',' + ROUTES + ',' , ID) - ID > 0
It may be necessary to use a cursor to loop through the CSV table and process each row (a loop within another loop...) but this is beyond my comprehesion of PL/SQL.
Many thanks in advance for your advice/help.

Not sure what you are trying to do with the last step, but this should work for the first part. I assume you would use sqlldr but I just did inserts instead. You might need more than 5 "routes" in the csv. You could put some reasonable max on that number of columns:
SQL>create table t_csv
2 (TPNUMBER varchar2(20),
3 ROUTE_1 VARCHAR2(5),
4 ROUTE_2 VARCHAR2(5),
5 ROUTE_3 VARCHAR2(5),
6 ROUTE_4 VARCHAR2(5),
7 ROUTE_5 VARCHAR2(5),
8 ROUTE_6 VARCHAR2(5) );
Table created.
SQL>INSERT INTO t_csv (TPNUMBER,ROUTE_1,ROUTE_2) values( '1001 1', '56W', '18' );
1 row created.
SQL>INSERT INTO t_csv (TPNUMBER,ROUTE_1,ROUTE_2,ROUTE_3) values( '1002 2', '16', '186', '28');
1 row created.
SQL>create table t_quotes(
2 tpnumber NUMBER,
3 routes VARCHAR2(5));
Table created.
SQL>DECLARE
2 L_tpnumber NUMBER;
3 L_route VARCHAR2(5);
4 begin
5 for rec in (select * from t_csv) loop
6 L_tpnumber := SUBSTR(rec.tpnumber,1,INSTR(rec.tpnumber,' ')-1);
7 L_route := SUBSTR(rec.tpnumber,INSTR(rec.tpnumber,' ')+1);
8 insert into t_quotes values( L_tpnumber, l_route );
9 if rec.route_1 is not null then
10 insert into t_quotes values( L_tpnumber, rec.route_1 );
11 end if;
12 if rec.route_2 is not null then
13 insert into t_quotes values( L_tpnumber, rec.route_2 );
14 end if;
15 if rec.route_3 is not null then
16 insert into t_quotes values( L_tpnumber, rec.route_3 );
17 end if;
18 if rec.route_4 is not null then
19 insert into t_quotes values( L_tpnumber, rec.route_4 );
20 end if;
21 if rec.route_5 is not null then
22 insert into t_quotes values( L_tpnumber, rec.route_5 );
23 end if;
24 end loop;
25 end;
