Query to find data on holidays
Hi, I have a table for special leave, which looks like this:
PROFILE_DAY | VAR_DATE |
---|---|
REGULAR_HOLIDAY | 01/01/2013 |
H_WEEK_THURSDAY | 28/03/2013 |
H_WEEK_FRIDAY | 29/03/2013 |
REGULAR_HOLIDAY | 24/12/2013 |
REGULAR_HOLIDAY | 25/12/2013 |
REGULAR_HOLIDAY | 31/12/2013 |
And another table (LOAD_PROFILE_TEST) that contains the values of (TIME_EQ) 0-24 LOAD_PROF1 intervals 0.25 for (PROFILE_DAY) MONDAY to SUNDAY including REGULAR_HOLIDAY, H_WEEK_THURSDAY and H_WEEK_FRIDAY. Overall, this table contains 970 records (97 separate 0-24 with interval of 0.25 per PROFILE_DAY, with 10 PROFILE_DAY).
TIME_EQ | PROFILE_DAY | LOAD_PROF1 | LOAD_PROF2 |
---|---|---|---|
0 | REGULAR_HOLIDAY | 11.47 | |
0.25 | REGULAR_HOLIDAY | 11.27 | |
0.5 | REGULAR_HOLIDAY | 11.3 | |
0.75 | REGULAR_HOLIDAY | 11.08 | |
0 | MONDAY | 11.27 | |
0.25 | MONDAY | 11.33 | |
0.5 | MONDAY | 11.18 |
Now I have this request to update the value of LOAD_PROF2 in the table every time that the V_DATE_OUT and V_DATE_IN parameters is entered:
UPDATE LOAD_PROFILE_TEST
SET LOAD_PROF2 = LOAD_PROF1 +: LOAD_DIFF
WHERE UPPER (PROFILE_DAY) IN (select UPPER (to_char (: V_DATE_OUT + (level 1), "fmDAY")))
of the double
connect by level < =: V_DATE_IN -: + 1 V_DATE_OUT
);
where: LOAD_DIFF is some predetermined value.
This query works fine if I'm trying to update regular days from MONDAY to SUNDAY. What I would do is to determine if the two dates of setting, V_DATE_OUT & V_DATE_IN would fall under none of the holidays on the first table LOAD_PROFILE_TEST, and then update the lines only. For example, V_DATE_OUT = 12/02/2013, Monday and V_DATE_IN = 06/12/2013, Friday. The query above would update the values of the LOAD_PROF2 for PROFILE_DAY - MONDAY to FRIDAY, corresponding to the dates of 02/12/2013 and on 06/12/2013. If, however, V_DATE_OUT = 23/12/2013, Monday and V_DATE_IN = 27/12/2013, Friday, it should update the lines corresponding to PROFILE_DAY - MONDAY 23/12/2013, THURSDAY for 26/12/2013, FRIDAY for 12 27, 2013, and REGULAR_HOLIDAY for the dates of 12 24, 2013 and 25/12/2013 since these two appear in the first table (table of holidays). This scenario works the same way when V_DATE_OUT and/or V_DATE_IN enter the dates of 28/03/2013 and 29/03/2013. All other dates not included in the table for special leave will be treated according to the day they fall on (from Monday to Sunday). I hope my point is clear. Thank you in advance.

I do not see the second statement in the create table and insert statements. Do you expect to write us your data ourselfs?
However I'll try it from scratch
merge into LOAD_PROFILE_TEST t

where
subsist = var_date (+)) g
on (UPPER (t.PROFILE_DAY) = g.profile_day

When matched then update

need help with query can find data back please help.
Hi guys I have a table such as
and I have a data as suchCREATE TABLE "FGL" ( "FGL_GRNT_CODE" VARCHAR2(60), "FGL_FUND_CODE" VARCHAR2(60), "FGL_ACCT_CODE" VARCHAR2(60), "FGL_ORGN_CODE" VARCHAR2(60), "FGL_PROG_CODE" VARCHAR2(60), "FGL_GRNT_YEAR" VARCHAR2(60), "FGL_PERIOD" VARCHAR2(60), "FGL_BUDGET" VARCHAR2(60) )
I need bascially to get the total of the budget column. However this is not as simple as it sounds good (at least not for the me.) totals carried forward to the new period. you will notice that you have a period column. Basically, what im is thatInsert into FGL (FGL_GRNT_CODE,FGL_FUND_CODE,FGL_ACCT_CODE,FGL_ORGN_CODE,FGL_PROG_CODE,FGL_GRNT_YEAR,FGL_PERIOD,FGL_BUDGET) values ('240055','240055','7600','4730','02','11','1','400'); Insert into FGL (FGL_GRNT_CODE,FGL_FUND_CODE,FGL_ACCT_CODE,FGL_ORGN_CODE,FGL_PROG_CODE,FGL_GRNT_YEAR,FGL_PERIOD,FGL_BUDGET) values ('240055','240055','7600','4730','02','10','1','100'); Insert into FGL (FGL_GRNT_CODE,FGL_FUND_CODE,FGL_ACCT_CODE,FGL_ORGN_CODE,FGL_PROG_CODE,FGL_GRNT_YEAR,FGL_PERIOD,FGL_BUDGET) values ('240055','240055','7240','4730','02','10','1','0'); Insert into FGL (FGL_GRNT_CODE,FGL_FUND_CODE,FGL_ACCT_CODE,FGL_ORGN_CODE,FGL_PROG_CODE,FGL_GRNT_YEAR,FGL_PERIOD,FGL_BUDGET) values ('240055','240055','7240','4730','02','10','14','200'); Insert into FGL (FGL_GRNT_CODE,FGL_FUND_CODE,FGL_ACCT_CODE,FGL_ORGN_CODE,FGL_PROG_CODE,FGL_GRNT_YEAR,FGL_PERIOD,FGL_BUDGET) values ('240055','240055','7600','4730','02','10','14','100'); Insert into FGL (FGL_GRNT_CODE,FGL_FUND_CODE,FGL_ACCT_CODE,FGL_ORGN_CODE,FGL_PROG_CODE,FGL_GRNT_YEAR,FGL_PERIOD,FGL_BUDGET) values ('240055','240055','7600','4730','02','10','2','100'); Insert into FGL (FGL_GRNT_CODE,FGL_FUND_CODE,FGL_ACCT_CODE,FGL_ORGN_CODE,FGL_PROG_CODE,FGL_GRNT_YEAR,FGL_PERIOD,FGL_BUDGET) values ('240055','240055','7470','4730','02','10','2','200');
fgl_grant_year 10 1 period = account 7600 its $100 and $100 for the period 2, you see $ 100 more, it wants to not be added to this is the door on the balance. that is $100.
So im trying to write a query that basically does the following.
IM considering a period for the sake of this example let period 1 I get anything else. I find that the greates contributes dumpster year the amount for the period 14 (which corresponds to the total of the previous year) and add it to the amount of the current year. in this case period 1 grnt_year 11
the expected result is therefore $700
do not forget that I am not given a just a period of the year.240055 240055 7240 4730 02 10 14 200 240055 240055 7600 4730 02 10 14 100 240055 240055 7600 4730 02 11 1 400
any help you guys can give would be immensely appreciated. I tried to get this to work for more than 3 days now.
Finally broke down and put together this post
Published by: mlov83 on Sep 14, 2011 20:48Hello
Thanks for posting the CREATE TABLE and INSERT statemnts; It is very useful.
I'm not sure that understand your needs.
The correct output will be just one line:TOTAL_BUDGET ------------ 700
or will it be 3 ranks that you posted? I guess you want just line after line.
Do you mean that you are given a period (for example, 1).
First you have to find the largest gfl_grnt_year which is related to this period (in this case, 11).
Then you need to add fgl_budget lines that have to be
(1) the specific period and the largest fgl_grnt_year, or
(2) perriod = 14 and the previous fgl_grnt_year (in this case, 10).
Is this fair?If so, here's a way to do it:
WITH got_greatest_year AS ( SELECT fgl.* -- or whatever columns are needed , MAX ( CASE WHEN fgl_period = :given_period THEN fgl_grnt_year END ) OVER () AS greatest_year FROM fgl ) SELECT SUM (fgl_budget) AS total_budget -- or SELECT * FROM got_greatest_year WHERE ( fgl_grnt_year = greatest_year AND fgl_period = :given_period ) OR ( fgl_grnt_year = greatest_year - 1 AND fgl_period = 14 ) ;
If you want the 3 lines you have posted, then change the main SELECT clause to ' SELECT * ' (or, instead of *, youcan the columns you want to see the list).

Query to find data conneting that intersect each other.
Hello
I have a table like road_point_ids (script is below). Basically, this table have road_id with its start and its end point.
I'm looking for a query that actually will connect each ID path beginning or end points.

Hi, Saaz,
How is this problem differs from your original problem?
If it's just that the data is now contained in 2 tables (a few lines in a table, a few lines in the other) instead of a table, you can change my original solution by using a UNION to combine the two tables into one:
WITH road_point_ids AS
(
SELECT road_id, start_point, end_point OF road_point_ids_1 UNION ALL
SELECT road_id, start_point, end_point FROM road_point_ids_2
)
SELECT DISTINCT road_id, start_point, end_point
OF road_point_ids
WHERE CONNECT_BY_ISCYCLE = 1
CONNECT BY NOCYCLE start_point = PRIOR end_point
;
The WITH clause is new; the main request is that I posted earlier.

I hope that answers your question.
If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
Simplify the problem. For example, pretend you're only interested in the first 3 or 4 months of 2012; We will find a solution tht can easily be adapted for 12 (or any other number) of motnhs.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

The best place is the manufacturer of your computer - try first. They should provide free drivers for the supported versions of Windows.
You can also try the individual hardware components manufacturers. For example, NVidia, AMD and Intel for graphics cards. In general, this should be free.
I would recommend avoiding utilities part 3rd pilot and Web sites, especially ones that cost money. It is usually unnecessary to use. He peut also have concerns quality and/or safety with some of them.
Windows Update can also provide drivers for some hardware. There is no cost and no real security issues by using this method, but drivers may be generic and lacking some features.
I prefer to install drivers when I want to and do it manually. It keeps me in control of the process and means if there is a problem it is easier to track what if its done to another more "in bulk".

Create the query by combining data from DBSS_Data_Model and HostModel
Hello
I am trying to create a dashboard with the host server list and instances of SQL Server running on the host.
And I am interested in creating a query by combining data model of data in SQL Server (DBSS_Data_Model) and the host (Hosts) data model, say: which connects DBSS_SQL_Server_Host and host.
I wonder if there is way to do it?
Thank you
Mark
Something like this function should work:
def physicalHost = nullqueryStatement = server.QueryService.createStatement("(Host where name = '$hostName')")result = server.QueryService.executeStatement(queryStatement)objs=result.getTopologyObjects() if (objs != null && objs.size() > 0) { physicalHost = objs.get(0)}return physicalHost
When the input parameter "hostName" is DBSS_SQL_Server_Host.physical_host_name
Kind regards

query to display data in table with several detail table
Hi all
I have a few cases with a table header that have more than 3 table of detail, and I have to generate the query to show all the data horizontally.
tblHdr have column A (PK)
tblDtl1 have column A (FK), B (PK)
tblDtl2 have column A (FK), C (PK)
tblDtl3 have column A (FK), D (PK)
and I need a query to display data like this:
A B1 C3 D1 A B2 C4 D2 A C5 D3 A C6 all the Details of the table should display data based on the relationship of tblHdr (A).
tblDtl1 have only 2 rows of data for the FK A
tblDtl2 just for FK 4 lines of data
tblDtl3 only 3 lines of data for the FK A
Another example:
A B1 C1 D1 A B2 C2 A B3
tblDtl1 only 3 lines of data for the FK A
tblDtl2 have only 2 rows of data for the FK A
tblDtl3 have only 1 rows of data for the FK A
Please shed some light. for the record, I'll use this query in ADF, so I'll put using PLSQL in second priority. I prefer to do it in the SQL query.
Thank you
Here are 3 ways. First test of data:
drop table ta purge; create table ta as SELECT 'A' AS A FROM dual union all select 'B' from dual; drop table tb purge; create table tb as SELECT 'A' AS A, 'B1' AS B FROM dual UNION ALL SELECT 'A', 'B2' FROM dual ; drop table tc purge; create table tc as SELECT 'A' AS A, 'C1' AS C FROM dual UNION ALL SELECT 'A', 'C2' FROM dual UNION ALL SELECT 'A', 'C3' FROM dual UNION ALL SELECT 'A', 'C4' FROM dual ; drop table td purge; create table td as SELECT 'A' AS A, 'D1' AS D FROM dual UNION ALL SELECT 'A', 'D2' FROM dual UNION ALL SELECT 'A', 'D3' FROM dual;
Now 3 solutions: full join, group by and pivot:
with b as ( select a, b, row_number() over(partition by a order by b) rn from tb ) , c as ( select a, c, row_number() over(partition by a order by c) rn from tc ) , d as ( select a, d, row_number() over(partition by a order by d) rn from td ) select a, b, c, d from ta left join b using(a) full join c using(a, rn) full join d using(a, rn) order by a, rn; select a, max(b) b, max(c) c, max(d) d from ( select a, null b, null c, null d, 1 rn from ta union all select a, b, null, null, row_number() over(partition by a order by b) rn from tb union all select a, null, c, null, row_number() over(partition by a order by c) rn from tc union all select a, null, null, d, row_number() over(partition by a order by d) rn from td ) group by a, rn order by a, rn; select A,B,C,D from ( select 'A' tab, a, null val, 1 rn from ta union all select 'B' tab, a, b, row_number() over(partition by a order by b) rn from tb union all select 'C' tab, a, c, row_number() over(partition by a order by c) rn from tc union all select 'D' tab, a, d, row_number() over(partition by a order by d) rn from td ) pivot(max(val) for tab in('B' B, 'C' C, 'D' D)) order by a, rn;
A B C D A B1 C1 D1 A B2 C2 D2 A C3 D3 A C4 B Personally, I would prefer to view the data by using a 'join the union', in order to avoid the impression that the different detail records are related somehow.
select ta.a, b, c, d from tb full join tc on 1=0 full join td on 1=0 right join ta on ta.a in (tb.a, tc.a, td.a);
A B C D A B1 A B2 A C1 A C2 A C3 A C4 A D1 A D2 A D3 B
