Need a little help if possible:
Got data as follows , but this is filtered , the INQUIRYID column is what i am trying to work with as this is the Inquiry Number of the booking:
The last column has the number of nights in I am trying to calculate using Excel 2007.
The Column INQ_DATE are the booked nights for the hotel stay , in this case , this enquiry is for 2 nights. Each booking has the amount of lines on it which equals the amount of nights they are staying for.
A second booking is as follows:
7 lines - INQUIRYID = 9501
This booking is for 7 nights , which differs from the first one above of 2 nights.
In the column at the end , i need to calculate the nights , on the filtered data .
there are two tables involved :
BOOKING_INQUIRY
BOOKING_INQUIRY_ROOMS
Linked on : INQUIRYID
So far i have:
In SQL(Which works but has specified a specific INQUIRYID)
SELECT DISTINCT COUNT(INQUIRYID)FROM dbo.BOOKING_INQUIRY_ROOMS
WHERE
inquiryid = '9501'
This returns 7
I know i am nearly there and need to adapt the WHERE clause , to maybe a dynamic parameter , but cant for the life of me how...
Can anyone help me please?
Thanks,
Matt
SELECT
inquiryid,
COUNT(*) as Nights
FROM
dbo.BOOKING_INQUIRY_ROOMS
GROUP BY
inquiryid
Just use GROUP BY...

I'm a non profit lawyer trying to set up a SQL Server database for my agency. The issue I'm having is query based: I need a simple query that will aggregate the total number of rows on a table, not the sum of the cell contents.
I working with 4 columns of I to: attorney's name, client name, trial date and remedy (the last 2 are date and dollar amount, so integers].
*** Script for SelectTopNRows command from SSMS***
SELECT TOP 100
[attorney]
,[client]
,[trial_date]
,[remedy]
FROM [MyLegalDB]
WHERE [trial_date] between '20160101' and '20160531'
I'm trying to find a way (script, batch file, etc) that will populate a total number of cases by month (according to trial date) total number of clients, and sum the remedy column.
Sorry for the vagueness. There are privilege rules in place. Hope that helps clarify.
Thanks
Assuming that your case history spans years, not just months, try this:
SELECT
,YEAR([trial_date]) AS [Year]
,MONTH([trial_date]) AS [Month]
,COUNT(1) AS [Trial_Count]
FROM [MyLegalDB]
WHERE [trial_date] between '20160101' and '20160531'
GROUP BY YEAR([trial_date]), MONTH([trial_date])
If you want to separate this by attorney, you would need to add that column to the SELECT list, as well as the GROUP BY clause, as such:
SELECT
[attorney]
,YEAR([trial_date]) AS [Year]
,MONTH([trial_date]) AS [Month]
,COUNT(1) AS [Trial_Count]
FROM [MyLegalDB]
WHERE [trial_date] between '20160101' and '20160531'
GROUP BY [attorney], YEAR([trial_date]), MONTH([trial_date])
This is a very general answer to a very general question. If you want me to be more specific, I'm going to have to understand your goal a little better. Hope it helps.
I'm new to T-SQL and this question is T-SQL Count 101.
I'm studying T-SQL with this site http://sqlmag.com/t-sql/t-sql-101-lesson-4 but I can't figure out Which part of coding says WHERE(column_name) to execute 'COUNT' if it makes sense? In other words, how does this COUNT know what to count? It just says COUNT everything as Reviews from MovieReview table.....
SELECT MovieName,
LEFT(REPLICATE('* ',AVG(Stars)),10)
AS 'Stars',
COUNT(*) AS 'Reviews'
FROM MovieReview
GROUP BY MovieName
HAVING COUNT(*) >= 4
ORDER BY Stars
Result:
The TABLE name is MovieReview that contains the ratings that the five employees have given to movies they’ve watched in their spare time. This table contains four columns: EmployeeID, Genre, MovieName, and Stars. The Stars field specifies the movie’s rating, where 1 star is the worst rating and 5 is the best rating.
I understand below coding because it specified WHERE. Count everything as '...' From Employee table Where salary is less than 3000.
SELECT COUNT(*)
AS 'Impoverished'
FROM Employee
WHERE Salary < 30000
I need to learn creating reports from Data Warehouse. I learned SQL but most of sites use T-SQL when creating reports, I don't know why.
Thanks in advance.
count(*) counts the number of rows that match the where clause if a where clause is given, per distinct combination of the group by columns if a group by column is given.
Except for the behavior noted in the previous sentence, count(*) ignores the values in those rows.
Hi im looking to compare several rows and check if a certain condition is true/false.
The tables has several columns the ones im interested in are:
Events.Badgeno
Events.Name
Events.Date
Events.Time
Events.Region_id
Events.Data
The region ID can either be 1 or 2.
I want to check weather the same badgeno registers with a different region within a specified date/time difference say 10 mins. (Could be 10 mins before or 10 mins after).
I'm looking to show the records which don't have a record against the 2 regions.
As a further note it should only be within the first and last records of that badge per day.
Normally each record should have a region 1 and 2 record at the start and end. But there maybe multiple region 1's through out the day.
Any suggestions for the best method?
Id Date Time Name Badgeid Region
3385033 27/02/2014 08:16:11 FirstName Surname 5304 2
I think something like this would work
SELECT e.Badgeno,e.Name, e.Date, e.Time,e.Region_id, e.Data
FROM events e
INNER JOIN events e1 ON e1.BadgeNo = e.BadgeNo AND e1.Region_id <> e.RegionId AND DATEDIFF(minutes,e1.date + e1.time,e.date + e.time) > -10 AND DATEDIFF(minutes,e1.date + e1.time,e.date + e.time) < 10
WHERE e1.Region_id IS NULL
you should provide sample data.
This Query is not complete,you can try something with
row_number/rank/dense, partition and check thus number column
generated .
select *,
row_number()over(partition by badgeno,regionno order by badge no)rn from table
where condition of date time
INTRODUCTION TO DATABASE TABLE BEING USED -
I am working on a “Stock Market Prices” based Database Table. My table has got the data for the following FIELDS –
ID
SYMBOL
OPEN
HIGH
LOW
CLOSE
VOLUME
VOLUME CHANGE
VOLUME CHANGE %
OPEN_INT
SECTOR
TIMESTAMP
New data gets added to the table daily “Monday to Friday”, based on the stock market price changes for that day. The current requirement is based on the VOLUME field, which shows the volume traded for a particular stock on daily basis.
REQUIREMENT –
To get the Average and Total Volume for last 10,15 and 30 Days respectively.
METHOD USED CURRENTLY -
I created these 9 SEPARATE QUERIES in order to get my desired results –
First I have created these 3 queries to take out the most recent last 10,15 and 30 dates from the current table:
qryLast10DaysStored
qryLast15DaysStored
qryLast30DaysStored
Then I have created these 3 queries for getting the respective AVERAGES:
qrySymbolAvgVolume10Days
qrySymbolAvgVolume15Days
qrySymbolAvgVolume30Days
And then I have created these 3 queries for getting the respective TOTALS:
qrySymbolTotalVolume10Days
qrySymbolTotalVolume15Days
qrySymbolTotalVolume30Days
PROBLEM BEING FACED WITH CURRENT METHOD -
Now, my problem is that I have ended up having these so many different queries, whereas I wanted to get the output into One Single Query, as shown in the Snapshot of the Excel Sheet:
http://i49.tinypic.com/256tgcp.png
SOLUTION NEEDED -
Is there some way by which I can get these required fields into ONE SINGLE QUERY, so that I do not have to look into multiple places for the required fields? Can someone please tell me how to get all these separate queries into one -
A) Either by taking out or moving the results from these separate individual queries to one.
B) Or by making a new query which calculates all these fields within itself, so that these separate individual queries are no longer needed. This would be a better solution I think.
One Clarification about Dates –
Some friend might think why I used the method of using Top 10,15 and 30 for getting the last 10,15 and 30 Date Values. Why not I just used the PC Date for getting these values? Or used something like -
("VOLUME","tbl-B", "TimeStamp BETWEEN Date() - 10 AND Date()")
The answer is that I require my query to "Read" the date from the "TIMESTAMP" Field, and then perform its calculations accordingly for LAST / MOST RECENT "10 days, 15 days, 30 days” FOR WHICH THE DATA IS AVAILABLE IN THE TABLE, WITHOUT BOTHERING WHAT THE CURRENT DATE IS. It should not depend upon the current date in any way.
If there is any better method or more efficient way to create these queries, then please enlighten.
You have separate queries to compute 10DayTotalVolume and 10DayAvgVolume. I suspect you can compute both in one query, qry10DayVolumes.
SELECT
b.SYMBOL,
Sum(b.VOLUME) AS 10DayTotalVolume,
Avg(b.VOLUME) AS 10DayAvgVolume
FROM
[tbl-B] AS b INNER JOIN
qryLast10DaysStored AS q
ON b.TIMESTAMP = q.TIMESTAMP
GROUP BY b.SYMBOL;
However, that makes me wonder whether 10DayAvgVolume can ever be anything other than 10DayTotalVolume / 10
Similar considerations apply to the 15 and 30 day values.
Ultimately, I think you want something based on a starting point like this:
SELECT
q10.SYMBOL,
q10.[10DayTotalVolume],
q10.[10DayAvgVolume],
q15.[15DayTotalVolume],
q15.[15DayAvgVolume],
q30.[30DayTotalVolume],
q30.[30DayAvgVolume]
FROM
(qry10DayVolumes AS q10
INNER JOIN qry15DayVolumes AS q15
ON q10.SYMBOL = q15.SYMBOL)
INNER JOIN qry30DayVolumes AS q30
ON q10.SYMBOL = q30.SYMBOL;
That assumes you have created qry15DayVolumes and qry30DayVolumes following the approach I suggested for qry10DayVolumes.
If you want to cut down the number of queries, you could use subqueries for each of the qry??DayVolumes saved queries, but try it this way first to make sure the logic is correct.
In that second query above, there can be a problem due to field names which start with digits. Enclose those names in square brackets or re-alias them in qry10DayVolumes, qry15DayVolumes, and qry30DayVolumes using alias names which begin with letters instead of digits.
I tested the query as written above with the "2nd Upload.mdb" you uploaded, and it ran without error from Access 2007. Here is the first row of the result set from that query:
SYMBOL 10DayTotalVolume 10DayAvgVolume 15DayTotalVolume 15DayAvgVolume 30DayTotalVolume 30DayAvgVolume
ACC-1 42909 4290.9 54892 3659.46666666667 89669 2988.96666666667
Access doesn't support most advanced SQL syntax and clauses, so this is a bit of a hack, but it works, and is fast on your small sample. You're basically running 3 queries but the Union clauses allow you to combine into one:
select
Symbol,
sum([10DayTotalVol]) as 10DayTotalV,
sum([10DayAvgVol]) as 10DayAvgV,
sum([15DayTotalVol]) as 15DayTotalV,
sum([15DayAvgVol]) as 15DayAvgV,
sum([30DayTotalVol]) as 30DayTotalV,
sum([30DayAvgVol]) as 30DayAvgV
from (
select
Symbol,
sum(volume) as 10DayTotalVol, avg(volume) as 10DayAvgVol,
0 as 15DayTotalVol, 0 as 15DayAvgVol,
0 as 30DayTotalVol, 0 as 30DayAvgVol
from
[tbl-b]
where
timestamp >= (select min(ts) from (select distinct top 10 timestamp as ts from [tbl-b] order by timestamp desc ))
group by
Symbol
UNION
select
Symbol,
0, 0,
sum(volume), avg(volume),
0, 0
from
[tbl-b]
where
timestamp >= (select min(ts) from (select distinct top 15 timestamp as ts from [tbl-b] order by timestamp desc ))
group by
Symbol
UNION
select
Symbol,
0, 0,
0, 0,
sum(volume), avg(volume)
from
[tbl-b]
where
timestamp >= (select min(ts) from (select distinct top 30 timestamp as ts from [tbl-b] order by timestamp desc ))
group by
Symbol
) s
group by
Symbol
I need to find out the total number of records that were created on a given day.
e.g.
ID CreatedDate
1 17/07/2009
2 12/07/2009
3 17/07/2009
4 05/07/2009
5 12/07/2009
6 17/07/2009
Output:
3 Records were created on 17/07/2009
2 Records were created on 12/07/2009
1 Record was created on 05/07/2009
EDIT
Upon testing the second suggestion made by Chris Roberts of including the formatting in the SQL i get this error:
Syntax error converting the varchar value ' Records were created on ' to a column of data type int.
Does anyone know how to rework the solution so that it works?
You should be able to get the data you're after with the following SQL...
SELECT COUNT(ID), CreatedDate
FROM MyTable
GROUP BY CreatedDate
Or - if you want to do the formatting in the SQL, too...
SELECT CONVERT(varchar, COUNT(ID)) + ' Records were created on ' + CONVERT(varchar, CreatedDate)
FROM MyTable
GROUP BY CreatedDate
Good luck!
Is the column actually a timestamp? In which case you will need to apply a function to remove the time component, e.g.:
SELECT COUNT(*), date(CreatedDate) FROM MyTable GROUP BY date(CreatedDate)
I don't know what the function is in T-SQL, it's date() in MySQL and trunc() in Oracle. You may even have to do a to_string and remove the end of the string and group by that if you lack this.
Hope this helps.
select count(*), CreatedDate from table group by CreatedDate order by count(*) DESC
