How can I find a missing values from a set of values, using SQL (Oracle DB)
e.g.
SELECT NAME
FROM ACCOUNT
WHERE ACCOUNT.NAME IN ('FORD','HYUNDAI','TOYOTA','BMW'...)
(The "IN" clause may contain hundreds of values)
If 'HYUNDAI' is missing in the ACCOUNT table, I need to get the result as "HYUNDAI".
Currently I use the result of the above query to do a Vlookup against the original set of values to find the missing values, I want to directly get the missing values without doing the Vlookup.
Thanks
Kiran,
You got it reversed. Do this: http://www.sqlfiddle.com/#!2/09239/3
SELECT Brand
FROM
(
-- Oracle can't make a row without a table, need to use DUAL dummy table
select 'FORD' as Brand from dual union
select 'HYUNDAI' from dual union
select 'TOYOTA' fom dual union
select 'BMW' from dual
) x
where Brand not in (select BrandName from account)
Sample Account data:
create table account(AccountId int, BrandName varchar(10));
insert into account(AccountId, BrandName) values
(1,'FORD'),
(2,'TOYOTA'),
(3,'BMW');
Output:
| BRAND |
-----------
| HYUNDAI |
Better yet, materialized the brands to a table:
select *
from Brand
where BrandName not in (select BrandName from account)
Output:
| BRANDNAME |
-------------
| HYUNDAI |
Sample data and live test: http://www.sqlfiddle.com/#!2/09239/1
CREATE TABLE Brand
(`BrandName` varchar(7));
INSERT INTO Brand
(`BrandName`)
VALUES
('FORD'),
('HYUNDAI'),
('TOYOTA'),
('BMW');
create table account(AccountId int, BrandName varchar(10));
insert into account(AccountId, BrandName) values
(1,'FORD'),
(2,'TOYOTA'),
(3,'BMW');
You should use Except: EXCEPT returns any distinct values from the left query that are not also found on the right query.
WITH SomeRows(datacol) --It will look for missing stuff here
AS( SELECT *
FROM ( VALUES ('FORD'),
('TOYOTA'),
('BMW')
) AS F (datacol)),
AllRows (datacol) --This has everthing
AS( SELECT *
FROM ( VALUES ('FORD'),
('HYUNDAI'),
('TOYOTA'),
('BMW')
) AS F (datacol))
SELECT datacol
FROM AllRows
EXCEPT
SELECT datacol
FROM SomeRows
You can do:
SELECT a.val
FROM
(
SELECT 'FORD' val UNION ALL
SELECT 'HYUNDAI' UNION ALL
SELECT 'TOYOTA' UNION ALL
SELECT 'BMW' UNION ALL
etc...
etc...
) a
LEFT JOIN account b ON a.val = b.name
WHERE b.name IS NULL
This worked perfectly, thanks Michael.
SELECT Brand
FROM
( -- Oracle can't make a row without a table, need to use DUAL dummy table
select 'FORD' as Brand from dual union
select 'HYUNDAI' from dual union
select 'TOYOTA' fom dual union
select 'BMW' from dual
)
where Brand not in (select BrandName from account)
Luxspes and Zane thank you for your inputs
Contributing Excel code to make the typing of the answer easier:
Say column A has the values (Ford, Hyundai,...).
In column B, put this in every cell:
select 'x' as brand from dual union
In column C, write this formula, and copy it down.
=REPLACE(A2,9,1,A1)
All of the select/union statements should appear in column C.

I have a table that in one column it have values separated by |, I need to sum those values to know the total value. example 5|4|3 = 12. I thinked that if I replace the | for a + symbol, that should work. But it doenst work.
Here is my code to create the table and what I am using to sum the values.
CREATE TABLE [dbo].[test_table](
[totals] [varchar](255) NULL
) ON [PRIMARY]
GO
--*******************
INSERT INTO [dbo].[test_table]
([totals])
-- VALUES
(
select ('1|5|13')
union
select ('1|5|13')
union
select ('0|0|2')
union
select ('1|1|7')
union
select ('1|1|13')
union
select ('1|1|13')
union
select ('0|0|3')
union
select ('0|0|1')
union
select ('0|0|4')
union
select ('1|1|9'))
GO
select
tot
--sum(tot) as total
--CONVERT(numeric, tot)
from
(
select totals,
replace(totals,'|','+') as tot
from test_table
) qry
SQL Server does not support macro substitution nor does if have an EVAL(). If you don't want to go with Dynamic SQL and your requirement is a simple aggregation, consider a CROSS APPLY in concert with a string_split()
Example
Select *
From [test_table] A
Cross Apply (
Select SumTotal = sum(try_convert(int,value))
from string_split(Totals,'|') B1
) B
Returns
totals SumTotal
0|0|1 1
0|0|2 2
0|0|3 3
0|0|4 4
1|1|13 15
1|1|7 9
1|1|9 11
1|5|13 19
In mssql-db I have a table with 5 columns.
id, 1st_t1, 1st_t2, 2nd_t1, 2nd_t2
it's single "task" with 2 parameters(t1,t2) "grouped" by person type(1st,2nd)
Is it possible to select info like this on picture in Reporting Service?:
Or the only way is divide this table on two tables for each person type?
In your report, your detail must have two rows.
On the first you will drag and drop the data of the 1st person and on the second row for the second like in the image below
Please try below query:
WITH T(ID, First_t1, First_t2, Second_t1, Second_t2)
AS
(
SELECT *
FROM
(
SELECT 1 ID, '1st_t1' First_t1, '1st_t2' First_t2, '2nd_t1' Second_t1, '2nd_t2' Second_t2
UNION
SELECT 2 ID, '1st_t1' First_t1, '1st_t2' First_t2, '2nd_t1' Second_t1, '2nd_t2' Second_t2
UNION
SELECT 3 ID, '1st_t1' First_t1, '1st_t2' First_t2, '2nd_t1' Second_t1, '2nd_t2' Second_t2
) A
)
SELECT * FROM
(
SELECT '1st person' person, Id,First_t1 t1,First_t2 t2 FROM T
union
SELECT '2nd person' person, Id,Second_t1 t1,Second_t2 t2 FROM T
) B
ORDER BY id
Please advise me on the following question:
I have two tables in an Oracle db, one that contains full numbers and the other that contains parts of them.
Table 1:
12323543451123
66542123345345
16654232423423
12534456353451
64565463345231
34534512312312
43534534534533
Table 2:
1232
6654212
166
1253445635
6456546
34534
435345
Could you please suggest a query that joins these two tables and shows the relation between 6456546 and 64565463345231, for example. The main thing is that Table 2 contains a lot more data than Table 1, and i need to find all the substrings from Table 2 that are not present in Table 1.
Thanks in advance!
Try this:
with t as (
select 123 id from dual union all
select 567 id from dual union all
select 891 id from dual
), t2 as (
select 1112323 id from dual union all
select 32567321 id from dual union all
select 44891555 id from dual
)
select t.id, t2.id
from t, t2
where t2.id||'' like '%'||t.id||'%'
You could try using the CONTAINS operator like this :
SELECT * FROM Table2 JOIN Table1 ON Table1.id=Table2.id
WHERE NOT CONTAINS (Table2.data, Table1.data)
Are numbers from table two in a set place in table 1? For example is the 1232 in the same place each time or do you have to search a sting for the numbers. If it's set you could use an inline select or a temp table and create a substring of the string your searching and then join the table or temp table on that field.
you first need to say if the number in Table 1 and 2 are repeated, if is not then I think this query would help you:
SELECT *
FROM Table_1
JOIN Table_2 ON Table_1.ID = Table_2.ID
WHERE Table_2.DATA LIKE Table_1.DATA
I am writing a query in which where clause have IN clause and there are large number of values in this IN clause , I want to fetch the result such that if there is no value exist in table for value given in IN clause then a raw containing 0 or null should return for that value. for example..
select age,sex,date_joining from emp where name IN ('amit','john','paul','dilip')
Now assume for this query ,data for john and paul does not exist in database then result should be like below..
21 male 21-AUG-2011
null null null
null null null
25 male 9-aug-2010
we can also have 0 instead of null if null is not possible
Thanks...
select filter.name
, emp.age
, emp.sex
, emp.date_joining
from (
values ('amit'), ('john'), ('paul'), ('dilip')
) filter(name)
left join
emp
on emp.name = filter.name
Live example at SQL Fiddle.
For older values of SQL Server, replace the line with values by:
from (
select 'amit'
union all select 'john'
union all select 'paul'
union all select 'dilip'
) filter(name)
You can also use common table expression to get this result:
;With AllEmpDetails as
(
Select [Name] from emp
UNION Select 'amit'
UNION Select 'john'
UNION Select 'paul'
UNION Select 'dilip'
)Select AllEmpDetails.Name, e2.Age, e2.Sex, e2.date_joining
from AllEmpDetails
Left Join emp e2 on e2.[Name] = AllEmpDetails.Name
In my database, I have already added details for amit and dilip so i have used UNION since you can easily get the detail about the available employees. On the other hand you can use UNION ALL with Distinct.
I have two tables. Table 1 is a master list of equipment with equipment_id and equipment_description. So, let's say for this table I have ten equipment_id's. 1,2,3....10 each with some description attached.
Table 2 logs when the equipment has been inspected:
equipment_id|inspection_date
1 | '1-22-2012'
2 | '1-22-2012'
4 | '1-22-2012'
2 | '1-23-2012'
3 | '1-23-2012'
I've created a view, v_dates which pulls out of table 2 all of the distinct inspection dates - not sure if I needed it but did it anyway.
I would like to create another view which shows all equipment that was NOT inspected for each date in the v_dates. So it would show:
3 | '1-22-2012'
5 | '1-22-2012'
and so on.
Rookie here and just not sure how to join these tables correctly. Can't get it to work and would appreciate any help.
Untested, but I think this should give the desired result:
SELECT i.id,d.date FROM
( SELECT DISTINCT inspection_date AS date FROM inspections ORDER BY 1 ) d
LEFT JOIN
inspections i
ON d.date=i.date
WHERE i.date IS NULL
GROUP BY 1,2
ORDER BY 1,2
Like mentioned in the comments would a table with inspection dates really help.
The following appears to work based on my test data using SQL SERVER 2005. I am using a CROSS JOIN of distinct dates along with a LEFT JOIN to throw out EQUIPMENT_ID records that exist for those dates.
Sorry, I am having problems getting my code formatting correct with tabs and spaces...
IF OBJECT_ID('tempdb..#EQUIPMENT') IS NOT NULL
DROP TABLE #EQUIPMENT
CREATE TABLE #EQUIPMENT
( EQUIPMENT_ID smallint,
EQUIPMENT_DESC varchar(32)
)
INSERT INTO #EQUIPMENT
( EQUIPMENT_ID, EQUIPMENT_DESC )
SELECT 1, 'AAA'
UNION SELECT 2, 'BBB'
UNION SELECT 3, 'CCC'
UNION SELECT 4, 'DDD'
UNION SELECT 5, 'EEE'
UNION SELECT 6, 'FFF'
UNION SELECT 7, 'GGG'
UNION SELECT 8, 'HHH'
UNION SELECT 9, 'III'
UNION SELECT 10, 'JJJ'
IF OBJECT_ID('tempdb..#INSPECTION') IS NOT NULL
DROP TABLE #INSPECTION
CREATE TABLE #INSPECTION
( EQUIPMENT_ID smallint,
INSPECTION_DATE smalldatetime
)
INSERT INTO #INSPECTION
( EQUIPMENT_ID, INSPECTION_DATE )
SELECT 1, '1-22-2012'
UNION SELECT 1, '1-27-2012'
UNION SELECT 3, '1-27-2012'
UNION SELECT 5, '1-29-2012'
UNION SELECT 7, '1-22-2012'
UNION SELECT 7, '1-27-2012'
UNION SELECT 7, '1-29-2012'
SELECT E.EQUIPMENT_ID, D.INSPECTION_DATE
FROM #EQUIPMENT E
CROSS JOIN ( SELECT DISTINCT INSPECTION_DATE
FROM #INSPECTION
) D
LEFT JOIN #INSPECTION I2
ON E.EQUIPMENT_ID = I2.EQUIPMENT_ID
AND D.INSPECTION_DATE = I2.INSPECTION_DATE
WHERE I2.EQUIPMENT_ID IS NULL
ORDER BY E.EQUIPMENT_ID, D.INSPECTION_DATE
As per my comment to the question, you really need a table of valid inspection dates. It makes the sql much more sensible, and besides it's the only way to do it if you want to see all items listed for dates when inspections were supposed to be done, but no inspections were done.
So, assuming the two tables:
create table inspections (equipment_id int, inspection_date date);
create table inspection_dates (id int, inspection_date date);
Then a join to get all the equipment that does not have an inspection on a date when an inspection should have taken place would be:
select i.equipment_id, id.inspection_date
from inspection_dates id,
(select distinct equipment_id from inspections) i
where not exists (select * from inspections i2
where i2.inspection_date = id.inspection_date
and i2.equipment_id = i.equipment_id);
You want the combos that do not exist. Thus the not exists predicate.
Note again, that presumably you would have a table for all the unique equipment_ids, but not knowing that I had to construct it myself in place.
