I am using the following insert query to create a comparison between two tables using the dates to join on.
INSERT INTO Comp_Table (Date, CKROne, CKRTwo, ChangeOne, ChangeTwo, State)
SELECT BaseTbl.Date, BaseTbl.CKR, CompTbl.CKR, BaseTbl.Change, CompTbl.Change,
CASE
WHEN BaseTbl.Change > 0 AND CompTbl.Change > 0 THEN 'positive'
WHEN BaseTbl.Change < 0 AND CompTbl.Change < 0 THEN 'positive'
ELSE 'inversely'
END AS 'Correlation'
FROM BaseTbl
JOIN CompTbl ON BaseTbl.Date = CompTbl.Date;
This works well. However, I would like to be able to join the tables with a lag. As in, the user can define if they want to do exact match on dates or if they want to use a date of one's occurrence plus a number and return the value from the latter date for comparison to the number to the former date. Pseudo code example:
User sets variable = 0 then
Join ComTbl On BaseTbl.Date = CompTbl.Date + 0;
User sets variable = 7 then
Join CompTbl On BaseTbl.Date = CompTbl.Date + 7;
(joins 2012-01-01 from BaseTbl to 2012-01-08 from CompTbl)
I tried to add days like you would in a Where clause ('+7 day'), but this didn't work. I also tried to using a Where clause with BaseTbl.Date = CompTbl.Date '+ 7 day' but that returned a 0 value also. How can this be accomplished in SQLite?
I think you can use the DATE() function to build the WHERE clause you want:
INSERT INTO ...
SELECT ...
FROM BaseTbl
INNER JOIN ComTbl
ON BaseTbl.Date = DATE(CompTbl.Date, '7 days')

This query worked perfectly until the moment I went in for vacations, now itdoes not run anymore and does not merge, dont know what it can be

when running this query returns me this error:
"The search condition must fully specify the Target table primary index and partition column(s) and expression must match INSERT specification primary index and partition column(s). "
I am having trouble with a query.
Fiddle: https://www.db-fiddle.com/f/JXQHw1VzF7vAowNLFrxv5/1
This is not going to work.
So my question is: What has to be done to get a result when I wanna use both conditions.
(attr_key = 0 AND attr_value & 201326592 = 201326592)
AND
(attr_key = 30 AND attr_value & 8 = 8)
Thanks in advance!
Best regards
One way to check for the presence of some number of key value pairs in the items_attributes table would be to use conditional aggregation:
SELECT i.id
FROM items i
LEFT JOIN items_attributes ia
ON i.id = ia.owner
GROUP BY
i.id
HAVING
SUM(CASE WHEN ia.key = 0 AND ia.value = 201326592 THEN 1 ELSE 0 END) > 0 AND
SUM(CASE WHEN ia.key = 30 AND ia.value = 8 THEN 1 ELSE 0 END) > 0
The trick in the above query is that we scan each cluster of key/value pairs for each item, and then check whether the pairs you expect are present.
Note: My query just returns id values from items matching all key value pairs. If you want to bring in other columns from either of the two tables, you may simply add on more joins to what I wrote above.
I would like to utilize the Month Column in the below syntax in a Case Statement. When I create a sub query I receive the Oracle error 01788 Connect By Clause Required in query block. How can one utilize the Month column in the case statment in the subquery?
TO_CHAR(ADD_MONTHS(TRUNC(StartDate, 'MM'), LEVEL - 1), 'YYYYMM') AS Month
Query below:
SELECT
CASE
WHEN first_assgn_dt_YYYYMM <= Month
THEN 0
WHEN EndDate < LAST_DAY(EndDate) AND EndDate != sysdate
AND LEVEL = 1 + MONTHS_BETWEEN(TRUNC(EndDate,'MM'),TRUNC(StartDate,'MM'))
THEN 0
ELSE 1
END AS active_at_month_end
FROM (
WITH
ActiveMemberData (ID,StartDate,EndDate,first_assgn_dt,first_assgn_dt_YYYYMM) AS (
SELECT DISTINCT
x.ID,
TRUNC(x.start_dt) AS StartDate,
CASE WHEN TRUNC(X.END_DT) = '1-JAN-3000' THEN SYSDATE ELSE TO_DATE(X.END_DT) END AS EndDate,
x.first_assgn_dt,
TO_CHAR(first_assgn_dt,'YYYYMM') AS first_assgn_dt_YYYYMM
FROM X
LEFT JOIN D ON X.MID = D.ID
WHERE 1=1
)
--------------------------------------------------
SELECT DISTINCT
ID,
first_assgn_dt,
first_assgn_dt_YYYYMM,
StartDate,
TO_CHAR(StartDate,'YYYYMM') AS StartDate_YYYYMM,
EndDate,
TO_CHAR(ADD_MONTHS(TRUNC(StartDate, 'MM'), LEVEL - 1), 'YYYYMM') AS Month,
LAST_DAY(EndDate) AS LastDayOfMonth
FROM ActiveMemberData
WHERE 1=1
------------------------------------------------------------------------------------
CONNECT BY LEVEL <= 1 + MONTHS_BETWEEN(TRUNC(EndDate,'MM'), TRUNC(StartDate,'MM'))
AND PRIOR ID = ID AND PRIOR STARTDATE = STARTDATE
AND PRIOR sys_guid() IS NOT NULL
) Z
WHERE 1=1
ORDER BY
ID,
Month
That has nothing to do with trying to refer to Month from the inline view; that is fine. It's the separate reference to level that is causing the error.
If you want to be able to see the level from your inline view in the outer query, as you are with this line:
AND LEVEL = 1 + MONTHS_BETWEEN(TRUNC(EndDate,'MM'),TRUNC(StartDate,'MM'))
then you have to include it in the select list - with an alias - and then refer to that alias:
SELECT
CASE
...
AND LEVEL_ALIAS = 1 + MONTHS_BETWEEN(TRUNC(EndDate,'MM'),TRUNC(StartDate,'MM'))
...
FROM (
...
SELECT DISTINCT
LEVEL as LEVEL_ALIAS,
ID,
...
You can call the alias whatever you want, of course; you just can't use the reserved word level.
Anything you want visible in the outer query always has to be in the inline view's select list - but usually you can keep the original column name; you have to use an alias for an expression or a pseucocolumn though, which is the case here.
You don't have to use an alias for the reserved word. Just add double quotes and capitilise it i.e. "LEVEL"
I am stuck with this requirement -
I have some data in the format
(Entries now show data for both periods (Jan. 2011) and (Feb. 2011) on the same line as apposed to appearing separately).
At the end I need to print the data using dbms_output.put_line command.
I am using Oracle 10.2g.
Oracle 10g does not have a PIVOT function but you can convert the rows of data into columns using an aggregate function with a CASE expression. The basic syntax would be:
select d.id,
d.site,
d.entrance,
sum(case when d.date = 'Jan.2011' then enters else 0 end) "Jan.2011",
sum(case when d.date = 'Feb.2011' then enters else 0 end) "Feb.2011"
from
(
select id, site, entrance, date, enters
from yourdata
) d
group by d.id, d.site, d.entrance;
Note: you can replace the subquery with yourdata with your current query.
I need some help to build SQL Query. I have table having data like:
ID Date Name
1 1/1/2009 a
2 1/2/2009 b
3 1/3/2009 c
I need to get result something like...
1 1/1/2009 a
2 1/2/2009 b
3 1/3/2009 c
4 1/4/2009 Null
5 1/5/2009 Null
6 1/6/2009 Null
7 1/7/2009 Null
8 1/8/2009 Null
............................
............................
............................
30 1/30/2009 Null
31 1/31/2009 Null
I want query something like..
Select * from tbl **where month(Date)=1 AND year(Date)=2010**
Above is not completed query.
I need to get all the record of particular month, even if some date missing..
I guess there must be equi Join in the query, I am trying to build this query using Equi join
Thanks
BIG EDIT
Now understand the OPs question.
Use a common table expression and a left join to get this effect.
DECLARE #FirstDay DATETIME;
-- Set start time
SELECT #FirstDay = '2009-01-01';
WITH Days AS
(
SELECT #FirstDay as CalendarDay
UNION ALL
SELECT DATEADD(d, 1, CalendarDay) as CalendarDay
FROM Days
WHERE DATEADD(d, 1, CalendarDay) < DATEADD(m, 1, #FirstDay)
)
SELECT DATEPART(d,d.CalendarDay), **t.date should be (d.CalendarDay)**, t.Name FROM Days d
LEFT JOIN tbl t
ON
d.CalendarDay = t.Date
ORDER BY
d.CalendarDay;
Left this original answer at bottom
You need DATEPART, sir.
SELECT * FROM tbl WHERE DATEPART(m,Date) = 1
If you want to choose month and year, then you can use DATEPART twice or go for a range.
SELECT * FROM tbl WHERE DATEPART(m,Date) = 1 AND DATEPART(yyyy,Date) = 2009
Range :-
SELECT * FROM tbl WHERE Date >= '2009-01-01' AND Date < '2009-02-01'
See this link for more info on DATEPART.
http://msdn.microsoft.com/en-us/library/ms174420.aspx
You can use less or equal to.
Like so:
select * from tbl where date > '2009-01-01' and date < '2009-02-01'
However, it is unclear if you want month 1 from all years?
You can check more examples and functions on "Date and Time Functions" from MSDN
Create a temporary table containing all days of that certain month,
Do left outer join between that table and your data table on tempTable.month = #month.
now you have a big table with all days of the desired month and all the records matching the proper dates + empty records for those dates who have no data.
i hope that's what you want.
