Transact SQL :: Find The Number Which Exists In Different Groups
May 25, 2015
I have a table which has 2 columns and the data is like below
API_Number       Group_Name
1234Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Group A
3241Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Group A

 I wanted to find the API numbers which are repeating in different groups. In the output I want
 API_Number          Group_Name
1234Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Group A,Group B

I need to find the missing months in a table for the earliest and latest start dates per ID_No.  As an example:
create table #InputTable (ID_No int ,OccurMonth datetime)
insert into #InputTable (ID_No,OccurMonth)Â
select 10, '2007-11-01' Union all
select 10, '2007-12-01' Union all
select 10, '2008-01-01' Union all
select 20, '2009-01-01' Union all
select 20, '2009-02-01' Union all
select 20, '2009-04-01' Union all
select 30, '2010-05-01' Union all
select 30, '2010-08-01' Union all
select 30, '2010-09-01' Union all
select 40, '2008-03-01'
For the above table, the answer should be:
ID_No OccurMonth
----- ----------
20 2009-02-01
30 2010-06-01
30 2010-07-01
1) don't include an ID column,
2) don't use the start date/end dates in the data or
3) use cursors, which are forbidden in my environment.

The following SQL works on Access and Oracle to return the number of
Groups(Rows) of the SQL. In MS-SQL this SQL is not valid. What is the
equivalent in MS-SQL?
Select Count(1) FROM (Select ShipRegion, Sum(FREIGHT) as [TotalFreight]
from ORDERS WHERE OrderID < 123456 GROUP BY ShipRegion )
Thanks,

hi,
not sure if the title really expains what I want to achieve...
I have a table which is like :
name groups number
bob 1 160
bob 51 160
bob 101 160
What I need to do is split the 160 into the correct groups..
so the first 50 goes into group 1, then next 50 in group 51, then the next 60 in 101..
so the result would look like :
name groups number
bob 1 50
bob 51 50
bob 101 60
thank you for any advice.

Counting groups
I have the following code that is grouped by name
Mike G ( from 2000 €“ 2003)
Address Raise
Test 1
Test 1
Mike G ( from 2004 €“ 2007)
Address Raise
Test 2 1
Test 2 1
Mark G ( from 2004 €“ 2007)
Address Raise
Test 2 1
Test 2 1
Total 6 (I get this without any problem)
The problem I am having is trying to find out how many groups we have to use the value for some other calculation. So I did this Count(Field .Name) wich will give me 6 instead of 3 . The reason is in my dataset it will be something like that
Name add raise Period
Mike G Test 1 2000-2003
Mike G Test 1 2000-2003
Mike G Test 1 2004-2004
Mike G Test 1 2004-2007
Mike G Test2 1 2004-2007
Mike G Test2 1 2004-2007
If I do CountDistinct(Field .Name) it will give me 2 which is also wrong . So how can I count many groups we have. I spend a lot of time on this please help!
Thanks

I'm trying to do the following and haven't been able to figure it out.
Say there's a table with these records:
Col1 Col2 Col3
a b c
a b c
a b d
e f g
e f g
I want to generate a number that represents the groups of columns like this:
Col1 Col2 Col3 MyNumber
a b c 1
a b c 1
a b d 2
e f g 3
e f g 3
So that each grouping gets its own identifier. I've tried this:
SELECT Col1, Col2, Col3
row_number() OVER (PARTITION BY Col1, Col2, Col3
ORDER BY Col1, Col2, Col3) AS MyNumber
FROM MyTable
But I get this:
Col1 Col2 Col3 MyNumber
a b c 1
a b c 2
a b d 1
e f g 1
e f g 2

I'm following these instructions: http://technet.microsoft.com/en-us/library/ms156421.aspx
I run this restore letting it create the database. It works fine:
RESTORE DATABASE ReportServer

WITH NORECOVERY,
MOVE 'ReportServer' TO
'G:DataReportServer.mdf',
MOVE 'ReportServer_log' TO
'J:LogsReportServer_Log.ldf';
GO
I run this command and get this result set, with the fileIDs in red.

then I run this LOG restore:
RESTORE LOG ReportServer

WITH NORECOVERY, FILE=2,
MOVE 'ReportServer2005' TO

Cannot find file ID 2 on device '\MYMACHINEe$BackupsReportingServicesReportServerLog.bak'.

RESTORE LOG is terminating abnormally.
I see file ID 2 identifying the log file. I've never done a restore like this - using copy_only and backing the database and log into separate .bak files, so maybe I'm misunderstanding something here.
Thanks for any help

insert into @tableÂ
select 4

The query selects 4 and 5 of course. Now what I'm looking for is to retrieve the number less or equal to @NumberToCompareTo, I mean the most immediate less number than the parameter. So in this case 5

I cannot figure out the SQL to return all policy number rows if there are more than 1 row with the policy. Most policies number will be in the table once. I need the others.

I need to calculate the last two columns (noofgrp and grpsize) No of Groups (count of Clientid) and Group Size (number of clients in each group) according to begtim and endtime. So I tried the following in the first Temp table
GrpSize= count(clientid) over (partition by begtime,endtime) else 0 end
and in the second Temp Table, I have
select
,GrpSize=sum(grpsize)
,NoofGrp=count(distinct grpsize)
From Temp1
The issue is for the date of 5/26, the begtime and endtime are not consistent. in Grp1 (group 1) all clients starts the session at 1030 and ends at 1200 (90 minutes session) except one who starts at 11 and end at 1200 (row 8). For this client since his/her endtime is the same as others, I want that client to be in the first group(Grp1). Reverse is true for the second group (Grp2). All clients begtime is 12:30 and endtime is 1400 but clientid=2 (row 9) who begtime =1230 but endtime = 1300. However, since this client begtime is the same as the rest, I wan that client to be in the second group (grp2) My partition over creates 4 groups rather than two.

I would have to handover my DB with only Primary tables to client as part of SLA.Â
I am planning to keep these primary tables on a secondary file-group but how-ever, I will still have my procedures on primary file-group.Â
How can I accomplish this with client having no exposure to my stored procedures.Â

I've been looking around for some kind of known issue or something, but can't find anything. Here's what I'm experiencing:
I have a table with about 50,000 rows. I open several connections and use a command to ExecuteResultSet against each command, with CommandType.TableDirect, CommandText set to the name of the table, and IndexName set to various indexes. In the end, I have several SqlCeResultSet instances which are then maintained for the life of the AppDomain.
In a loop, I call SqlCeResultSet.Read() on one of the instances, and if it returns false, I call SqlCeResultSet.ReadFirst() - essentially creating a circular pass through the result set.
In a Visual Studio debug session, this approach goes swimmingly for a short time, and then after a successful Read(), I'm pegged with an InvalidOperationException (text: "No data exists for the row/column") for a column which was succesfully read on the previous Read(). If, in the immediate window, I call SqlCeResultSet.Read() again on the result set instance, the Get___ methods work as they had been in the previous reads.
It seems like the internal state of the ResultSet is getting corrupted somehow, but it is opaque to me. Any insights on why this suddenly throws this exception?

Is there a way to find active connection to a database so you don't have to wait for a restore or similar operation to fail. (Which take forever).?
Is there a SMO method or a transact SQL command or something that can be used in an application to detect active connections?
I don't want to have to wait forever to get a failure when you can't perform a operation that require that there be no active connection such detach a database. I want to be able to tell when I can perform a operation which requires no active connection and when I need to use a task without out dropping the connection like copying the schema using SMO methods.
However if there are no connection I can perform a detach copy and attach to create a new database which is considerable faster.

I am trying to bulk update about 50,000 rows in a SQL table. Â The values that the table MUST contain are:
1-3 days
4-7 days
8-10 days
Some of the rows contain a space between the number and the hyphen like:
1 - 3 days
4 - 7 days
8 - 10 days
What would be my best methodology of removing the space between numerics only? Â I have seen multiple examples of how to remove ALL whitespace, but I only want to remove the space between the numbers and the hyphen *IF* it exists. And the field type is varchar(200)

I'm currently setting up a Tabular Model to do some research between several fact tables. Â In this example i have two fact tables (table 1 and table 2)Â which I've created a 1 to 1 relationship on phone number. Â Typically I create a relationship between these tables to find common data between the two. Â However, in this case I am trying to figure out the best way to model the data so that I can easily surface data from one table that does not exist in the other. Â I would liken this to a LEFT JOIN or a WHERE NOT EXISTS in SQL.
Table 1 has all of the data and Table 2 Only has a subset of the data from Table 1. Â What I'm trying to do here is display what attributes in Table 1 may play a part in records not existing in Table 2. What is the best way to model this?

Ok, I'm looking to get counts on historical data where the number of records exists between two dates with different years. The trick is the that the dates fall in different years. Ex: Give me the number of records that are dated between 0ct 1, 2013 and July 1, 2014.
A previous post of mine was similar where I needed to get records after a specific date. The solution provided for that one was the following. This let me get any records that occured after May 1 per given Fiscal year.
SELECT
MAX(CASE WHEN DateFY = 2010 THEN Yr_Count ELSE 0 END) AS [FY10],
MAX(CASE WHEN DateFY = 2010 THEN May_Count ELSE 0 END) AS [May+10],
MAX(CASE WHEN DateFY = 2011 THEN Yr_Count ELSE 0 END) AS [FY11],
MAX(CASE WHEN DateFY = 2011 THEN May_Count ELSE 0 END) AS [May+11],
MAX(CASE WHEN DateFY = 2012 THEN Yr_Count ELSE 0 END) AS [FY12],
[Code] ....
I basically need to have CASE WHEN MONTH(OccuranceDate) between Oct 1 (beginning year) and July 1 (ending year).

When i am running below snippet execution plan is showing constant scan instead of referring subquery table.
I want to know how this query working. and why in execution plan there is no scan /seek which will basically indicate that particular table is getting referred.
select count(*) from AÂ where exists (select count(1) from B where A.a=B.a)
execution plan has to show scan or seek for subquery. Surprisingly, output is coming as expected.

When I execute the below queries it works perfectly where as my expectation is, it should break.
Select * from ChildDepartment C where C.ParentId IN (Select Id from TestDepartment where DeptId = 1)
In TestDepartment table, I do not have ID column. However the select in sub query works as ID column exists in ChildDepartment.  If I do change the query to something below then definately it will break -
Select * from ChildDepartment C where C.ParentId IN (Select D.Id from TestDepartment D where D.DeptId = 1)
Shouldn't the default behavior be otherwise? It should throw error if column doesnt exists in sub query table and force me to define the correct source table or alias name.
create table TestDepartment
(
DeptId int identity(1,1) primary key,
name varchar(50)
)
create table ChildDepartment
(
Id int identity(1,1) primary key,
