I have a set of values in a variable table #vartable
id
34
235
34634
3643536
23
234
I then want to do the following insert -
insert into tableA
values ((select max(tableA_id)+1 from tableA), 2147, (select id from #vartable), 1, 0, 0)
So for each id in the #vartable it does an insert using the id on the row.
How do I go about this?
edit to note that I need to update the first value (select max(tableA_id)+1 from tableA) as increasing by 1 each new row it inserts.
insert into tableA (ColName1,ColName2,ColName3,ColName4,ColName5,ColName6)
Select (select max(tableA_id)+1 from tableA), 2147, id , 1, 0, 0
from #vartable
If you need the Max number to be increment, use below query which use ROW_NUMBER
Insert into tableA (ColName1,ColName2,ColName3,ColName4,ColName5,ColName6)
Select (ROW_NUMBER()
OVER (ORDER BY Id)+(select max(tableA_id) from tableA) )as aRow,
2147, id , 1, 0, 0
From #vartable

I have a sample data like this
Declare #table Table
(
ID INT,
Value VARCHAR(10),
Is_failure int
)
insert into #table(ID, Value, Is_failure) values (1, 'Bits', 0)
insert into #table(ID, Value, Is_failure) values (2, 'Ip', 0)
insert into #table(ID, Value, Is_failure) values (3, 'DNA', 0)
insert into #table(ID, Value, Is_failure) values (6, 'DCP', 1)
insert into #table(ID, Value, Is_failure) values (8, 'Bits', 0)
insert into #table(ID, Value, Is_failure) values (11, 'calc', 0)
insert into #table(ID, Value, Is_failure) values (14, 'DISC', 0)
insert into #table(ID, Value, Is_failure) values (19, 'DHCP', 1)
Looks like this:
ID Value Is_failure
1 Bits 0
2 Ip 0
3 DNA 0
6 DCP 1
8 Bits 0
11 calc 0
14 DISC 0
19 DHCP 1
Data continuous like this ... I need to fetch top 2 records along with Is_failure whenever Is_failure = 1 comes if it is 0 no need to pick up .
Sample output:
ID Value Is_failure
2 Ip 0
3 DNA 0
6 DCP 1
11 calc 0
14 DISC 0
19 DHCP 1
Suggest on this I have tried with having count(*) and other things but not fruitful.
You can use this query
Declare #tmptable Table
(
ID INT,
Value VARCHAR(10),
Is_failure int,
rowNum int
)
Declare #continuousRows int =2
insert into #tmptable
select *,ROW_NUMBER() over (order by id) from #table
;with cte1 as
(select *
from #tmptable t
where (select sum(Is_failure) from #tmptable t1 where t1.rowNum between t.rowNum-#continuousRows and t.rowNum
having count(*)=#continuousRows+1)=1
and t.Is_failure=1
)
,cte2 as
(
select t.* from #tmptable t
join cte1 c on t.rowNum between c.rowNum-#continuousRows and c.rowNum
)
select c.ID,value,Is_failure from cte2 c
You can use window functions for this:
select id, value, is_failure
from (select t.*,
lead(Is_failure) over (order by id) as next_if,
lead(Is_failure, 2) over (order by id) as next_if2
from #table t
) t
where 1 in (Is_failure, next_if, next_if2)
order by id;
You can simplify this with a windowing clause:
select id, value, is_failure
from (select t.*,
max(is_failure) over (order by id rows between current row and 2 following) as has_failure
from #table t
) t
where has_failure > 0
order by id;
Table1
Id bigint primary key identity(1,1)
Status nvarchar(20)
Insert dummy data
Insert into Table1 values ('Open') --1
Insert into Table1 values ('Open') --2
Insert into Table1 values ('Grabbed') --3
Insert into Table1 values ('Closed') --4
Insert into Table1 values ('Closed') --5
Insert into Table1 values ('Open') --6
How would I construct a single select statement which orders the data where records with 'Grabbed' status is first, followed by 'Closed', followed by 'Open' in SQL Server
Output:
Id Status
3 Grabbed
4 Closed
5 Closed
1 Open
2 Open
6 Open
I think you need something like this:
select *
from yourTable
order by case when Status = 'Grabbed' then 1
when Status = 'Closed' then 2
when Status = 'Open' then 3
else 4 end
, Id;
[SQL Fiddle Demo]
Another way is to using CTE like this:
;with cte as (
select 'Grabbed' [Status], 1 [order]
union all select 'Closed', 2
union all select 'Open', 3
)
select t.*
from yourTable t
left join cte
on t.[Status] = cte.[Status]
order by cte.[order], Id;
[SQL Fiddle Demo]
This could be done much better with a properly normalized design:
Do not store your Status as a textual content. Just imagine a typo (a row with Grabed)...
Further more a lookup table allows you to add side data, e.g. a sort order.
CREATE TABLE StatusLookUp(StatusID INT IDENTITY PRIMARY KEY /*you should name your constraints!*/
,StatusName VARCHAR(100) NOT NULL
,SortRank INT NOT NULL)
INSERT INTO StatusLookUp VALUES
('Open',99) --ID=1
,('Closed',50)--ID=2
,('Grabbed',10)--ID=3
CREATE TABLE Table1(Id bigint primary key identity(1,1) /*you should name your constraints!*/
,StatusID INT FOREIGN KEY REFERENCES StatusLookUp(StatusID));
Insert into Table1 values (1) --1
Insert into Table1 values (1) --2
Insert into Table1 values (3) --3
Insert into Table1 values (2) --4
Insert into Table1 values (2) --5
Insert into Table1 values (1) --6
SELECT *
FROM Table1 AS t1
INNER JOIN StatusLookUp AS s ON t1.StatusID=s.StatusID
ORDER BY s.SortRank;
I find that the simplest method uses a string:
order by charindex(status, 'Grabbed,Closed,Open')
or:
order by charindex(',' + status + ',', ',Grabbed,Closed,Open,')
If you are going to put values in the query, I think the easiest way uses values():
select t1.*
from t1 left join
(values ('Grabbed', 1), ('Closed', 2), ('Open', 3)) v(status, priority)
on t1.status = v.status
order by coalesce(v.priority, 4);
Finally. This need suggests that you should have a reference table for statuses. Rather than putting the string name in other tables, put an id. The reference table can have the priority as well as other information.
Try this:
select Id,status from tablename where status='Grabbed'
union
select Id,status from tablename where status='Closed'
union
select Id,status from tablename where status='Open'
I've inherited a SQL Server database that has duplicate data in it. I need to find and remove the duplicate rows. But without an id field, I'm not sure how to find the rows.
Normally, I'd compare it with itself using a LEFT JOIN and check that all fields are the same except the ID field would be table1.id <> table2.id, but without that, I don't know how to find duplicates rows and not have it also match on itself.
TABLE:
productId int not null,
categoryId int not null,
state varchar(255) not null,
dateDone DATETIME not null
SAMPLE DATA
1, 3, "started", "2016-06-15 04:23:12.000"
2, 3, "started", "2016-06-15 04:21:12.000"
1, 3, "started", "2016-06-15 04:23:12.000"
1, 3, "done", "2016-06-15 04:23:12.000"
In that sample, only rows 1 and 3 are duplicates.
How do I find duplicates?
Use having (and group by)
select
productId
, categoryId
, state
, dateDone
, count(*)
from your_table
group by productId ,categoryId ,state, dateDone
having count(*) >1
You can do this with windowing functions. For instance
create table #tmp
(
Id INT
)
insert into #tmp
VALUES (1), (1), (2) --so now we have duplicated rows
WITH CTE AS
(
SELECT
ROW_NUMBER() OVER(PARTITION BY Id ORDER BY Id) AS [DuplicateCounter],
Id
FROM #tmp
)
DELETE FROM CTE
WHERE DuplicateCounter > 1 --duplicated rows have DuplicateCounter > 1
For some reason I thought you wanted to delete them I guess I read that wrong but just switch DELETE in my statement to SELECT and now you have all of the duplicates and not the original. But using DELETE will remove all duplicates and still leave you 1 record which I suspect is your desire.
IF OBJECT_ID('tempdb..#TT') IS NOT NULL
BEGIN
DROP TABLE #TT
END
CREATE TABLE #TT (
productId int not null,
categoryId int not null,
state varchar(255) not null,
dateDone DATETIME not null
)
INSERT INTO #TT (productId, categoryId, state, dateDone)
VALUES (1, 3, 'started', '2016-06-15 04:23:12.000')
,(2, 3, 'started', '2016-06-15 04:21:12.000')
,(1, 3, 'started', '2016-06-15 04:23:12.000')
,(1, 3, 'done', '2016-06-15 04:23:12.000')
SELECT *
FROM
#TT
;WITH cte AS (
SELECT
*
,RowNum = ROW_NUMBER() OVER (PARTITION BY productId, categoryId, state, dateDone ORDER BY productId) --note what you order by doesn't matter
FROM
#TT
)
--if you want to delete them just do this otherwise change DELETE TO SELECT
DELETE
FROM
cte
WHERE
RowNum > 1
SELECT *
FROM
#TT
If you want to and can change schema you can always add an identity column after the fact too and it will populate the existing record
ALTER TABLE #TT
ADD Id INTEGER IDENTITY(1,1) NOT NULL
You can try CTE and then limit the actual selection from the CTE to where RN = 1. Here is the query:-
;WITH ACTE
AS
(
SELECT ProductID, categoryID, State, DateDone,
RN = ROW_NUMBER() OVER(PARTITION BY ProductID, CategoryID, State, DateDone
ORDER BY ProductID, CategoryID, State, DateDone)
FROM [Table]
)
SELECT * FROM ACTE WHERE RN = 1
My script is as below
CREATE TABLE #t (Id int, Name varchar(10))
INSERT INTO #t VALUES (1, 'A')
INSERT INTO #t VALUES (1, 'B')
INSERT INTO #t VALUES (1, 'C')
INSERT INTO #t VALUES (1, 'D')
INSERT INTO #t VALUES (2, 'E')
SELECT COUNT(0)FROM (SELECT COUNT(0) FROM #t GROUP BY Id) a
but I am getting an error
Msg 8155, Level 16, State 2, Line 5
No column name was specified for column 1 of 'A'.
When you use a subquery, all the columns need to given names:
SELECT COUNT(0)
FROM (SELECT COUNT(0) as cnt FROM #t GROUP BY Id
) a;
However, a simpler way to write this is:
SELECT COUNT(DISTINCT id)
FROM #t;
Actually, this isn't exactly the same. Your version will count NULL values but this does not. The exact equivalent is:
SELECT COUNT(DISTINCT id) + MAX(CASE WHEN id IS NULL THEN 1 ELSE 0 END)
FROM #t;
Table1
ID Value
001 100
002 125
003 150
004 175
005 200
006 225
...
Expected Output
If the user enters a value between 100 to 124, then id should display 001
If the user enters a value between 125 to 149, then id should display 002
If the user enters a value between 200 to 224, then id should display 005
If the user enters a value between 225 to 249, then id should display 006
How to make a query for the above condition.
Need query help
It'd be easier to write query to transformed table like ID, ValueFrom, ValueTo.
For this table:
SELECT MAX(ID)
FROM Table1
WHERE Value <= #value
Basically, if 155 is entered, IDs 1 2 and 3 are returned, then MAX ID is taken (3) which is the answer.
Here you go:
First create the test table:
CREATE TABLE #Temp(ID INT, Val INT)
INSERT INTO #Temp VALUES(1, 100);
INSERT INTO #Temp VALUES(2, 125);
INSERT INTO #Temp VALUES(3, 150);
INSERT INTO #Temp VALUES(4, 175);
INSERT INTO #Temp VALUES(5, 200);
INSERT INTO #Temp VALUES(6, 225);
Set up the test value
DECLARE #value INT
SET #value = 125
If ID is sequential (i.e. 1, 2, 3, 4, 5, etc)
SELECT t1.id
FROM #Temp t1, #Temp t2
WHERE t1.ID = t2.ID -1
AND #value BETWEEN t1.Val AND t2.Val -1
If ID is not sequential (i.e. 1, 2, 5, 7, 8, etc)
;WITH cte AS (SELECT ROW_NUMBER() OVER (ORDER BY id) AS rownum, ID, Val FROM #Temp)
SELECT t1.id
FROM cte t1, cte t2
WHERE t1.rownum = t2.rownum -1
AND #value BETWEEN t1.Val AND t2.Val -1
Get the closest match and return first row previously sorting by value:
select top 1 id
from range
where value <= #value
order by value desc
Or, if you need to incorporate this query into another:
select id
from range
where value = (select max(value) from range where value <= #value)
Use CASE in SELECT statement....
Eg:
declare #c int;
set #c=120;
SELECT
CASE
WHEN #c BETWEEN 100 AND 124 THEN '001'
WHEN #c BETWEEN 125 AND 149 THEN '002'
ELSE 'Other'
END
