Get Count And Average Number Of Records Per Month

Sep 12, 2006

Example table structure:
Id int, PK
Name varchar
AddDate smalldatetime

Sample data:
Id Name  AddDate
1  John  01/15/2005
2  Jane  01/18/2005
.
.
.
101  Jack  01/10/2006
102  Mary  02/20/2006

First, I need to find the month which has the most records, I finally produced the correct results using this query but I am not convinced it's the most efficient way, can anyone offer a comment or advice here?

select top 1 count(id), datename(mm, AddDate) mth, datepart(yy, AddDate) yr
  from dbo.sampletable
  group by datename(mm, AddDate), datepart(yy, AddDate)
  order by count(id) desc

Also, I'm really having trouble trying to get the overall average of records per month. Can anyone suggest a query which will produce only one number as output?

How To Count Number Of Selected Records And Store Result To Another Column

Jul 4, 2012

Code:

SELECT ((ACOS(SIN(34.37769 * PI() / 180) * SIN(latitude * PI() / 180)
+ COS(34.37769 * PI() / 180) * COS(latitude * PI() / 180) * COS((132.404738 - longitude)
* PI() / 180)) * 180 / PI()) * 60 * 1.1515) AS ranges FROM completeyuubinwithlatlon having ranges<=3

First, I have that code whenever i disregard the "having ranges<=3" it selects record but when I include it it returns error. The problem is I want to just select records with ranges less than 3 miles..how do I do that.. and I want to count the number of selected rows and store it on a column on the same table.

Transact SQL :: Adding Count Before And After A Specific Time Doesn't Match Total Number Of Records

Nov 19, 2015

If I just use a simple select statement, I find that I have 8286 records within a specified date range.

If I use the select statement to pull records that were created from 5pm and later and then add it to another select statement with records created before 5pm, I get a different count: 7521 + 756 = 8277

Is there something I am doing incorrectly in the following sql?

DECLARE @startdate date = '03-06-2015'
DECLARE @enddate date = '10-31-2015'
DECLARE @afterTime time = '17:00'
SELECT
General_Count = (SELECT COUNT(*) as General FROM Unidata.CrumsTicket ct

[Code] ....

Count Distinct In Large Table With 30M Records?

Jul 7, 2015

I have a task to count distinct records in a big table with roughly 30M records, performance is an important factor. Query is to be written to calculate weekly stats, weekly record number could be as high as 1M.

The actual result is like:
ID Policy
350235744Credit Cards
350235744PCI
350235744PCI Audit

So the final number for this particular Policy is 3

I can write the query like:

select count(distinct Incident_id) policy_name
from Reporting_DailyDlpDetail
Where (year(INSERT_DETECT_TS)=2015) and (month(INSERT_DETECT_TS) =6) and (day(INSERT_DETECT_TS) between 2 and 9)
This returns 526254 and costs 11 seconds to complete

or a query like:
Select distinct Incident_id, policy_name
from Reporting_DailyDlpDetail
Where (year(INSERT_DETECT_TS)=2015) and (month(INSERT_DETECT_TS) =6) and (day(INSERT_DETECT_TS) between 2 and 9)
This returns 749687 and costs roughly 1 minute to complete.

Result is different from the two queries, I believe the later gives correct number. How can I count the distinct based on a combo?Considering the size of data, what is the best and most efficient way to run the stats calculation against over 30 different scenarios (different policies and alert types) and not timeout?

Simple Count Function - Show All Records For SSN In A Table

Jul 9, 2013

I want my query to list all SSNS that have more than one record in the table. I have this query:

Code:

SELECT SSN, name4, count(*) from [1099_PER]
group by SSN, name4
having count(SSN) > 1

It does retrieve the right SSNS and tells me how many times the SSN occurs in the table. However, I want my query results to display their full records.

For example

SSN NAME4 COUNT
123445555 WALTER - 4

I want the query to show me all four records for this SSN. I thought removing the count field would do this, but it still gives me only one instance of each SSN.

SQL 2012 :: Count Records From Each Separate Data Table Corresponding To Feed

Nov 5, 2014

I have 1 table that is just a list of feeds. A, B, C, D etc (15 rows in total) and each feed has other information attached to it such as Full name, location etc etc. I am only interested in the Feed column.

Each feed then has a corresponding data table which contains a list of records. Eg Feed A data is contained in TableA, Feed B data is contains in TableB and so on.

Basically what I need is a combined table that shows the list of Feeds in the 1st Column ( So A, B, C, D…..) and then a second column which counts the records from each separate data table corresponding to that feed.

So the end result would look something like this:

Feed------No of Records
A----------4 (from TableA)
B----------7 (from TableB)
C----------8 (from TableC)
D----------1 (from TableD)

Possible?

The Best Way To Delete A Huge Number Of Records In Table

May 30, 2008

Hi Everyone,



We have a large test database with million of records for more than company site Code. Sometime we want to refresh the data of that database for one or more site Codes.

In order to do that I have to delete all records of the site code we want to refresh on the test database first then copy a new set of data from production database over. Since we refresh data based on the site code therefore I have to use the Delete command instead of Truncate.

Since this is a huge database with thousand of tables and million of records per table I have a performance issues with delete command. So what would be the best to delete a large number of records without writing any information to database log file?



FYI: The Recovery model of this database is Simple


Regards,



Jdang

MDX: Count Records In Table A That Are Not In Table B

May 23, 2007

Hello all,



I would like to use MDX to identify "contracts" which are in a table A and not in a table B, and count them to have a total per "company".

It should be something like:



Contract / Flag contracts not in table B (1=yes, 0=not)

---------------------------------------------------------------

Contract 1 1

Contract 2 0

Contract 3 1

Contract 4 1

Contract 5 0

Contract 6 0

TOTAL 3



So far I know how to distinguish at contract level which records belong to table A and not table B, but I do not have the total for the company.



In SQL it should be something like that:

SELECT Company,count(*)

FROM tableA

left join tableB

on tableA.Contract = tableB.Contract

WHERE tableB.Contract is null

GROUP BY Company



Thanks,

Guillaume

TSQL Stored Procedure - Get Count Where....

Feb 23, 2007

I have the following for sql server 2000...
  Select b.courseName, a.courseId, count(a.courseId) as [count],  avg(convert(INT, a.fldScore)) as [average], count(fldPass) as [passed], count(fldPass) as [failed] From tblTest a  inner join tblTest2 b on a.courseId = b.courseId Group by a.courseId, b.courseName
Problem is the [passed] and [failed]
As it is, it's counting all of them.
I need to adjust it so passed will only read where fldPass = 'yes'
and fldPass = 'no' for the passed and failed.
Suggestions?
Thanks,
Zath

TSQL - Create A Variable Number Of Rows

May 4, 2008

I have a booking system which stores an event along with a start date and a finish date. I want to create a table which has a row for each day the event is on. I can find the number of days easily enough using a datediff function but I don't know how to translate this into that number of rows. My current thinking is to cross join the original table out to another temporary table with a large number of rows and use SQL2005 to only select the top 'x' rows, then use the rownumber of this temp table to add the required number of days to the StartDate to get each eventdate. Currently I use a loop to build the required table but there must be a way to get it all done in a single statement :)
Thanks



ORIGINAL DATA
EventID StartDate EndDate
1 1/1/08 1/1/08
2 20/1/08 22/1/08


REQUIRED DATA
EventID EventDate
1 1/1/08
2 20/1/08
2 21/1/08
2 22/1/08

How To Count The Number Of Textboxes

Feb 5, 2007

Hi all,
 
In the report I am working on, I have a "textbox39" in a table which has groups. I want to have another "textbox29" outside the table to count the number of "textbox39"s that are actually displayed and also the number of "textbox1"s that have a certain value (e.g. "1") in the final report. I tried to use "Sum(ReportItems!textbox39.Value)" but the compiler complains
 
Error 1 [rsAggregateReportItemInBody] The Value expression for the textbox 'textbox29' uses an aggregate function on a report item.  Aggregate functions can be used only on report items contained in page headers and footers. d:perfperfreportingprojectPerformanceTestDetails v.3.rdl 0 0 

 
Error 7 [rsReportItemReference] The Value expression for the textbox €˜textbox29€™ refers to the report item €˜textbox39€™.  Report item expressions can only refer to other report items within the same grouping scope or a containing grouping scope. d:perfperfreportingprojectPerformanceTestDetails v.3.rdl 0 0 
 
Anybody has any idea how to solve it?
Thanks so much,
Zhiyan

How To Automatically Create New Records In A Foreign Table When Inserting Records In A Primary Table.

Sep 13, 2006

Ok, I'm really new at this, but I am looking for a way to automatically insert new records into tables.  I have one primary table with a primary key id that is automatically generated on insert and 3 other tables that have foreign keys pointing to the primary key.  Is there a way to automatically create new records in the foreign tables that will have the new id?  Would this be a job for a trigger, stored procedure?  I admit I haven't studied up on those yet--I am learning things as I need them. Thanks.

ExecuteNonQuery To Count Number Of Rows??

Sep 5, 2007

My understanding from a previous thread was that ExecuteNonQuery() could be used to display the number of rows returned.
Does this also work when calling stored procedures and passing parameters?
I have code (shown) that perfectly calls and returns Distinct models downloaded by Country. Yet the rowCount variable displays a -1.
What should I do?Dim myCommand As New SqlClient.SqlCommand
myCommand.CommandText = "ap_Select_ModelRequests_RequestDateTime"
myCommand.CommandType = CommandType.StoredProcedure
myCommand.Parameters.AddWithValue("@selectDate", dateEntered)
myCommand.Parameters.AddWithValue("@selectCountry", CInt(selectCountry))
myCommand.Connection = con
con.Open()
Dim rowCount As Integer = myCommand.ExecuteNonQuery()
numberParts.Text = rowCount.ToString
con.Close() Thank you.
