DISTINCT query not working its give me repeated columns on output - c#

Buddy
i have one query of MSSQL.
that is like this..
SELECT DISTINCT resource.locationurl,
resource.resourcename,
resource.anwserid,
checktotal.total
FROM resource
INNER JOIN (SELECT Count(DISTINCT anwserid) AS total,
resourcename
FROM resource AS Resource_1
WHERE ( anwserid IN (SELECT Cast(value AS INT) AS Expr1
FROM dbo.Udf_split(#sCategoryID, ',')
AS
udf_Split_1) )
GROUP BY resourcename) AS checktotal
ON resource.resourcename = checktotal.resourcename
WHERE ( resource.anwserid IN (SELECT Cast(value AS INT) AS Expr1
FROM dbo.Udf_split(#sCategoryID, ',') AS
udf_Split_1)
)
AND ( checktotal.total = #Total )
ORDER BY resource.resourcename
I run this query but its give me repeated column of Resource.LocationURL.
you can check it live hear http://www.ite.org/visionzero/toolbox/default2.aspx
check in above link where you can fire select some category but result was not distinct..
i try most of my but now i am out of mind please help me with this.

You misunderstand what DISTINCT means when you are fetching more than one column.
If you run this query:
SELECT DISTINCT col1, col2 FROM table
You are selected every different combination. An acceptable result would be
value 1_1, value 2_1
value 1_1, value 2_2,
value 2_1, value_2_1
In this example, value 1_1 appears twice, but the two columns combined are unique.
My guess is that you are actually attempting to perform a grouping:
SELECT resource.locationurl,
resource.resourcename,
resource.anwserid,
Sum(checktotal.total)
FROM resource
INNER JOIN (SELECT Count(DISTINCT anwserid) AS total,
resourcename
FROM resource AS Resource_1
WHERE ( anwserid IN (SELECT Cast(value AS INT) AS Expr1
FROM dbo.Udf_split(#sCategoryID, ',')
AS
udf_Split_1) )
GROUP BY resourcename) AS checktotal
ON resource.resourcename = checktotal.resourcename
WHERE ( resource.anwserid IN (SELECT Cast(value AS INT) AS Expr1
FROM dbo.Udf_split(#sCategoryID, ',') AS
udf_Split_1)
)
AND ( checktotal.total = #Total )
GROUP BY resource.locationurl,
resource.resourcename,
resource.anwserid

First of all, the site you linked doesn't do anything.
Second, DISTINCTensures unique rows. It will not make the values in all the columns unique as well. Just think about it! How would it work? You have two rows with the same locationurl field, but with otherwise distinct elements. Which one do you not include?
Lastly, please take greater care in phrasing your questions.

as I see your query is select DISTINCT on multi columns,
so if any record has at least one col difference then it pass the DISTINCT condition
Ex:
record1 : locationurl | resourcename | anwserid | Sum(checktotal.total)
loc1 res1 1 100
record2 : locationurl | resourcename | anwserid | Sum(checktotal.total)
loc1 res1 2 100

How to select multiple Row and multiple field by one code with SQL

I want to select multiple row on a table. But I want to select fields every row too. Here is sample table :
---------------------
OrNo | Name | value
---------------------
1154 | Michael | 41
1154 | Rico | 24
1487 | Alex | 21
1487 | Leo | 27
I want to select based where "Orno" code which in the table is multiple. so I want to get every name and value on 1 of "OrNO".
For an example, I want to select where OrNO 1154. How to select all of name and value from that code? How to used sql data reader for read them?
Edit:
Based answered, I'm sorry, I want to execute on behind code, like sqldatareader with C#/VB.Net. I dont know how to execute them on behind code to store to varriable.
Thank you
SELECT *
FROM MyTable
WHERE OrNo IN
(
SELECT OrNo
FROM
(
SELECT OrNo, COUNT(*) AS RecordCount
FROM MyTable
GROUP BY OrNo
) A
WHERE RecordCount > 1
)
You want to return duplicate records per OrNo, so count per OrNo and only return records with a count > 1.
select orno, name, value
from
(
select orno, name, value, count(*) over (partition by orno) as cnt
from mytable
)
where cnt > 1
order by orno;
It's hard to understand your question.
Are you searching for the SQL Statement? If so, I would suggest:
SELECT *
FROM <TABLE_NAME>
WHERE OrNo IN
(
SELECT OrNo
FROM <TABLE_NAME>
GROUP BY OrNo
HAVING COUNT(*) > 1
)
Sorry, #jmcilhinney was faster here.
And one more, with ties
with t as (
select * from (values
(1154,'Michael',41),
(1154,'Rico',24),
(1199,'Mary',25),
(1487,'Alex',21),
(1487,'Leo',27)) t(OrNo, Name, value )
)
select top(1) with ties OrNo, Name, value
from t
order by
case count(*) over (partition by OrNo ) when 1 then 1 else 0 end

How do I grab only the latest Invoice Number

I have Invoice Numbers that are stored as nvarchar(25).
Their Format is ‘####AA’
Where #### is the Invoice Number and AA is the Version Number (partial Order Shipping)
I cannot change the format.
I created two Scalar Functions:
CREATE FUNCTION [dbo].[fnNumbersFromStr](#str varchar(8000))
RETURNS int
AS
BEGIN
WHILE PATINDEX('%[^0-9]%',#str)> 0
SET #str = REPLACE(#str, SUBSTRING(#str, PATINDEX('%[^0-9]%', #str), 1), '')
RETURN CAST(#str AS INT)
END
And it’s brother:
CREATE FUNCTION [dbo].[fnStringFromNum](#str varchar(25))
RETURNS varchar(25)
AS
BEGIN
WHILE PATINDEX('%[^a-z]%',#str)> 0
SET #str = REPLACE(#str, SUBSTRING(#str, PATINDEX('%[^a-z]%', #str), 1), '')
RETURN #str
END
I am stalled with this script:
SELECT
strInvoiceNo,
dbo.fnNumbersFromStr(strInvoiceNo) AS [InvoiceNumber],
dbo.fnStringFromNum(strInvoiceNo) AS [InvoiceString]
FROM #TempTable
Which when runs returns:
strInvoiceNo InvoiceNumber InvoiceString
1000A 1000 A
1000B 1000 B
1000C 1000 C
1001A 1001 A
1001B 1001 B
1002AA 1002 AA
1002AB 1002 AB
1003A 1003 A
1004A 1004 A
I just can’t figure out the next step from here. I am stuck.
I would like the select to only return the latest Invoice Versions:
1000C
1001B
1002AB
1003A
1004A
Sql, Lamda or Linq will work fine for me.
Thanks in advance,
Try this:
SELECT
InvoiceNumber + MAX(InvoiceString) As strInvoiceNo
FROM
(
SELECT
dbo.fnNumbersFromStr(strInvoiceNo) AS [InvoiceNumber],
dbo.fnStringFromNum(strInvoiceNo) AS [InvoiceString]
FROM #TempTable
) As tbl
GROUP BY InvoiceNumber
I dont think you need any UDF for this, a simple windowing function query should return what you looking for.
WITH x AS
(
Select *
,ROW_NUMBER() OVER (PARTITION BY InvoiceNumber ORDER BY strInvoiceNo DESC) rn
FROM TableName
)
SELECT strInvoiceNo, InvoiceNumber, InvoiceString
FROM X
WHERE rn = 1
OR
SELECT strInvoiceNo, InvoiceNumber, InvoiceString
FROM
(
Select *
,ROW_NUMBER() OVER (PARTITION BY InvoiceNumber ORDER BY strInvoiceNo DESC) rn
FROM TableName
)x
WHERE rn = 1
Here is it in LINQ (Assuming fnStringFromNum returns a string padded on the left with spaces):
dbContext.YOURTABLE
.GroupBy(x=>UDFFunctions.fnNumbersFromStr(x.AccountNumber))
.Select(x=>x.OrderByDescending(y=>UDFFunctions.fnStringFromNum(y.AccountNumber).FirstOrDefault())
SQL (using current fnStringFromNum):
SELECT
InvoiceNumber + LTRIM(MAX(RIGHT(SPACE(20)+InvoiceString,20))) As strInvoiceNo
FROM
(
SELECT
dbo.fnNumbersFromStr(strInvoiceNo) AS [InvoiceNumber],
dbo.fnStringFromNum(strInvoiceNo) AS [InvoiceString]
FROM #TempTable
) As tbl
GROUP BY InvoiceNumber
Not necessarily the most efficient, but this will work:
select strInvoiceNo
from #TempTable T
where InvoiceString = (select max(invoicestring) from temp1 where invoicenumber = T.invoicenumber)
order by 1
Edit: Sorry....disregard. This will work off of your full result table but may not be what you actually need. Apologies.

SQL Server : how to detect unregarded values from a range of integers

I have a problem, in example: I have a range of ids of integers (from 1 to 1000), this range supposed to be ids in a SQL Server table, and I want to detect which numbers of this range are not in the table, and sorry for my bad english, thank you
another simpler option would be to use the following query
SELECT number
FROM master..spt_values
WHERE number BETWEEN 1 AND 1000
AND NOT EXISTS ( SELECT 1
FROM Your_Table t --<-- your table where you are checking
WHERE t.ID = number) -- the missing values
GROUP BY number
The above solution is only good if you are looking for around 1000 values. For more values you would need to modify it little bit, something like
-- Select the maximum number or IDs you want to check
DECLARE #Max_Num INT = 10000;
;WITH CTE AS
(
SELECT TOP (#Max_Num) ROW_NUMBER() OVER ( ORDER BY (SELECT NULL)) numbers
FROM master..spt_values v1 cross join master..spt_values v2
)
SELECT c.numbers
FROM CTE c
WHERE NOT EXISTS (SELECT 1
FROM Your_table t
WHERE t.ID = c.numbers)
One way to find "holes" is to generate a list of all possible values and then look for the ones that aren't there. If you can survive with a list of a missing value and then the number of subsequent values following it, you can do this with another method.
SQL Server 2012+ supports lead() and lag(). The following gets almost everything, except for initial missing values:
select t.id + 1 as missingid,
(coalesce(t.nextid, 1000) - t.id - 1) as nummissing
from (select t.*, lead(t.id) over (order by t.id) as nextid
from table t
t.id between 1 and 1000
) t
where t.nextid > t.id + 1 or
(t.nextid is null and t.id <> 1000)
You can get these with a little piece of special logic:
select (case when t.previd is null then 1
else t.id + 1
end) as missingid,
(case when t.previd is null then t.id - 1
else (coalesce(t.nextid, 1000) - t.id - 1)
end) as nummissing
from (select t.*, lead(t.id) over (order by t.id) as nextid,
lag(t.id) over (order by t.id) as previd
from table t
where t.id between 1 and 1000 and
) t
where (t.nextid > t.id + 1 or
(t.nextid is null and t.id <> 1000)
(t.previd is null and t.id <> 1)
)
This sounds like one of the many scenarios where it is helpful to have a numbers table:
SELECT *
FROM lkp_Numbers a
WHERE NOT EXISTS (SELECT 1
FROM YourTable b
WHERE a.num = b.Id)
AND num <= 1000
I use this to create a numbers table:
DROP TABLE lkp_Numbers
DECLARE #RunDate datetime
SET #RunDate=GETDATE()
SELECT TOP 1000 IDENTITY(int,1,1) AS Num
INTO lkp_Numbers
FROM sys.objects s1, sys.objects s2, sys.objects s3
ALTER TABLE lkp_Numbers ADD CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Num)
That method for creating a numbers table was found here: What is the best way to create and populate a numbers table?

Assign query results to variables and select all variables in resultset [duplicate]

I am generating a report in php (mysql),
ex:
`select count(id) as tot_user from user_table
select count(id) as tot_cat from cat_table
select count(id) as tot_course from course_table`
Like this I have 12 tables.
Can i make it in single query. If i did? Process gets slow?
SELECT (
SELECT COUNT(*)
FROM user_table
) AS tot_user,
(
SELECT COUNT(*)
FROM cat_table
) AS tot_cat,
(
SELECT COUNT(*)
FROM course_table
) AS tot_course
If you use MyISAM tables, the fastest way is querying directly the stats:
select table_name, table_rows
from information_schema.tables
where
table_schema='databasename' and
table_name in ('user_table','cat_table','course_table')
If you have InnoDB you have to query with count() as the reported value in information_schema.tables is wrong.
You can certainly us the a Select Agregation statement as Postulated by Ben James, However This will result in a view with as many columns as you have tables. An alternate method may be as follows:
SELECT COUNT(user_table.id) AS TableCount,'user_table' AS TableSource FROM user_table
UNION SELECT COUNT(cat_table.id) AS TableCount,'cat_table' AS TableSource FROM cat_table
UNION SELECT COUNT(course_table.id) AS TableCount, 'course_table' AS TableSource From course_table;
The Nice thing about an approch like this is that you can explicitly write the Union statements and generate a view or create a temp table to hold values that are added consecutively from a Proc cals using variables in place of your table names. I tend to go more with the latter, but it really depends on personal preference and application. If you are sure the tables will never change, you want the data in a single row format, and you will not be adding tables. stick with Ben James' solution. Otherwise I'd advise flexibility, you can always hack a cross tab struc.
select RTRIM(A.FIELD) from SCHEMA.TABLE A where RTRIM(A.FIELD) = ('10544175A')
UNION
select RTRIM(A.FIELD) from SCHEMA.TABLE A where RTRIM(A.FIELD) = ('10328189B')
UNION
select RTRIM(A.FIELD) from SCHEMA.TABLE A where RTRIM(A.FIELD) = ('103498732H')
SELECT t1.credit,
t2.debit
FROM (SELECT Sum(c.total_amount) AS credit

WHERE c.status = "a") AS t1,

WHERE d.status = "a") AS t2
I know this is an old stack but i will post this Multi-SQL select case

LINQ adding columns to base result set

I have three classes, Code,CodeContact and Contact which map to tables in a database. In my code the classes have one static method which returns the data you'll find in the following SQL script
create table #Contacts
(ContactId int
,Name varchar(50)
,Phone varchar(50)
)
insert into #Contacts(ContactId,Name,Phone)
values (1,'jon',111 )
,(2,'jim',222)
,(3,'james',333)
,(4,'john',444)
,(5,'tim',555)
,(6,'jane',666)
go
create table #ContactsCodes
(ContactId int
,CodeId int
)
insert into #ContactsCodes(ContactId,CodeId)
values (1,1 )
,(1,2 )
,(1,3 )
,(1,4 )
,(2,2 )
,(2,3 )
,(3,1 )
,(3,4 )
,(4,1 )
,(4,5 )
create table #Codes
(CodeId int
,CodeText varchar(50)
)
insert into #Codes
values (1,'Code Red' )
,(2,'Code Blue' )
,(3,'Code Green' )
,(4,'Code Gray' )
,(5,'Code Black' )
,(6,'code clear' )
I'm looking for some advice on how to get LINQ code to acieve something like that following
declare #filter varchar(50) = (select 1)
select c.ContactId
,c.Name
,c.Phone
,case when varColumn.ContactId is null
then 'Not Present'
else 'Present' end as [Code Red]
,case when varColumn2.ContactId is null
then 'Not Present'
else 'Present' end as [Code Blue]
from Contacts as c
--****************end of 'cohort' base set of IDs
--first item in filter list becomes a
--column on a DataTable
left join
(
select distinct cc.ContactId
from Codes as codes
left join ContactsCodes as cc
on cc.CodeId = codes.CodeId
where codes.CodeId =#filter
) as varColumn on varColumn.ContactId = c.ContactId
--second item in filter becomes another column
left join
(
select distinct cc.ContactId
from Codes as codes
left join ContactsCodes as cc
on cc.CodeId = codes.CodeId
where codes.CodeId =#filter+1
) as varColumn2 on varColumn2.ContactId = c.ContactId
So let's say I have an IEnumerable with 1,2,3 in it. I would like to iterate over the collection and left join to the Contact.ContactId column and simply give an indication if that particular CodeId was found in the ContactsCodes table. Here's what the result looks like if you run the above SQL:
I will eventually need the tackd on column data to be pretty dynamic. But for the time being, can anyone provide a direction to go? I think the easiest choice might be to go the LINQ to SQL route and have the stuff inside the left join a stored procedure and call it X number of times for whatever's in the list, but I'm welcome to any suggestions.
