sql function to calculate work hours of an employee - Database Discussion Boards

1. Some "more" (more than JOIN) information would help.
2. Read the guidelines at the top of this page.
3. Where is the question?

Greetings

So idea of what databases you're working with would help.

Please help me to JOIN 2 table from different server.

Now, to answer your question; execute sp_addlinkedserver[^] to link the two servers, then using the server name to fully qualify a table, write a join in the normal way.

This post assumes MS SQL Server.

Thank you for your reply.
I am really really sorry for my uncomplete question.
I am using SQL server 2000.

@J4amieC, Thank you. Will try with "sp_addlinkedserver[^]".

I have a table in MS Access 2007 database I want to make a chart with, column chart (or whichever one is vertical). The table holds information on various species of insect I recorded over the year, so I could have multiple records for one species. Anyway what I have wanted to do, but haven't been able to figure out what is that:

I wanted to make a chart that had Jan, feb, march (all the way to december) on the X axis and up the Y axis I wanted a number (not sure of the number needed on it, up to 500 possibly) and what I wanted to do with the chart is show how many of a particular species I found each month of the year.

The fields I wanted to get the information with from the table are the scientific name, date, stage and quantity. The scientific name will be displayed as the title of the table and this is the species I want to find out about. The date is the date that month I recorded the species and the quantity is how many I recorded on that date. I have another field which is called "stage" and when you open the chart it will ask you two things, the scientific name and the stage as the stage (adult, larvae etc...) is quite inomrtant to what I want and I want the stage to be displayed on the chart.

Just say I wanted to know about Pieris Napi, I want to type this in when I open the chart, next type in Adult as the stage and I would get a chart showing Jan-December and the total I found each month in a column chart with its scientific name dispayed on title and stage (wether its an adult or pupae etc..)

Anyone know how would I do this? I think I would need to make a query from the table to get the information on the scientific name and stage, but not sure what else to do, any help would be appreciated.

In the end we're all just the same

I think you probably want to use a parametrized query with species as input.
I'm slightly confused about the stage - should the chart only show the selected stage or all stages?
If you go this route then the query should group by month and stage. That should easily be done in designer.
An alternative might be to use a PivotTable as the source for the chart.

My Access is pretty rusty but I think this is fairly straightforward. I'm not too good on charts - never really used them in Access.

Would it be better to give the user a list of species and allow them to select from the list. Saves all sorts of bother if the user gets the spelling wrong.

Hi Dave,

First, for stage, prefer a drop down list to choose the stage and the results change accordingly, just show one type of stage, say a table showing the Pieris Napi at adult stage only.

What you suggested on having a drop down list to chose the scientific name would be far better, how would I do this so you can choose what you want proir to creating the table, would an input form work best for this, choose the scientific name and stage on a small form then press a button to take you to a chart on that species. I know how to create the form, but not how to get the information onto a chart

Havn't used much with charts or inputting data except on tables latley, so I am a bit rusty.

Hi All,

I want to get all the values of a column as comma separated values in SQL Server. Can anybody help me writing the query for that.

Thanks in advance.

Thanks & Regards,

Here is an example

DECLARE @String VARCHAR(1000)

SET @String = ''

SELECT @String = @String + ',' + Column1
FROM Table1

SELECT @String

Hi guys,
I am having an inlined table valued function to search the users in my site.
The search is optional ie. sometimes user will search with first name, sometimes he searches with last name, and sometimes both.
As of now I am using if-else statements to check whether first name is ''(empty),or last name is ''(empty) or both are ''(empty).

I have two questions?

1. Is there any other way, so that I can avoid these if-else statements and make it a single query?
2. If I am using a function as shown below, I have to specify all the return parameters. Is there any way I can avoid this and return the complete table(I do not want to use stored procedures)?

I'm using a freetext search,because I want to get the search results according to relevence(ranked results).

ALTER FUNCTION [dbo].[Search]
(

@FirstName Varchar(400),@LastName Varchar(400)
)
RETURNS
@SearchResults TABLE
(
-- Add the column definitions for the TABLE variable here
UserName Varchar(400),
EmailAddress Varchar(400)
)
AS
BEGIN

IF (@FirstName<>'' AND @LastName<>'')
begin
insert into @SearchResults
Select Top 100 Percent UserName,EmailAddress
From UsersFirst t
JOIN FreetextTable(UsersFirst, FirstName, @FirstName) K On t.Id = K.[Key]
JOIN UsersSecond U on t.UserId=U.Id
JOIN FreetextTable(UsersSecond, LastName, @LastName) As L On U.Id = L.[Key]
ORDER BY K.[Rank] DESC;
end
ELSE IF (@FirstName<>'')
begin
insert into @SearchResults
Select Top 100 Percent UserName,EmailAddress
From UsersFirst t
JOIN FreetextTable(UsersFirst, FirstName, @FirstName) K On t.Id = K.[Key]
JOIN UsersSecond U on t.UserId=U.Id
ORDER BY K.[Rank] DESC;
end

return
END

Thanks In Advance

Dear Friend's,

My Issue scenario is as follow's

i have two servers Name
"Server_A"
"Server_B"

In "Server_A" i have one Database "DB1"
In "Server_B" i have one Database "DB2"

in Database "DB1" of Server "Server_A" i have one table "tbl_ListOfCountry"

now as per my business logic that table must be centralize where my client will update information and i need to use this table data in "Server_B".

For that i have create one procedure which pull all the data of table "tbl_ListOfCountry" from "Server_A".

for that i have created Synonym "tbl_ListOfCountry"
using following syntex

CREATE SYNONYM [dbo].[tbl_ListOfCountry] FOR [Server_A].[DB1].[dbo].[tbl_ListOfCountry]

now for security purpose i have created one user "user1" with "Server Role" as "Public" and "User Mapping" as "db_datareader", "db_datawriter" and "public" in "Server_B"

and Grant As Execute Permission of this user to my procedure "Proc1" which use to pull the record.

now the main issue is started

whenever i execute that procedure "Proc1" using "user1" login instead of "sa" it give me error

Msg 18456, Level 14, State 1, Line 1
Login failed for user 'user1'.

Please, help me to overcome this issue...

Thanks in advanced..

Sasmi

Let me guess. The password for the 'sa' account on DB1(ServerA) is the same as on DB2(ServerB). Smile | :)

Thanks for the quick reply...

I am also think same but when i am using this Procedure in my application it is giving me same error can you explain me why this happening....

I suspect that it works when you are logged in to DB2 as 'sa', because it attempts to use those same credentials on DB1, it will work since 'sa' also exists in DB1 with the same password. When you login to DB2 with 'XYZ', the same login will be attempted on DB1 and since 'XYZ' doesn't exist on DB1, the login fails. The quick and dirty solution is to replicate the userid on DB1 and I suspect that will allow the link to work. Smile | :)

if the shift time is 7pm to 3am..after 12am,it will be considered as next day..and the time after 12am will be calculated as work hour of next day..please help me to write a sql function for this..pls...

Check this out:

http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html

Things you may want to consider when designing a system which includes a start time and end time:

1) Store both the date and time. This will make it much easier to determine if a shift crosses a midnight boundary.

2) Use the concept of a "End of Day" time. For example, lots of manufacturing sites use 11pm (23:00) because they consider anyone working after 11pm to be working the next day.

3) Also take into consideration a "Pay Date", typically this is what is considered the day the person works (and gets paid for). For example if your worker starts his shift on Friday at 7pm and works into Saturday morning, he would be paid for working Friday. Not 2 different pay days. (Fri & Sat)

Best of luck.

Time can be a real nightmare to handle. Other issues which you might want to think about include:

Day-light saving time (esp. around midnight boundaries).
Time zones -- don't look applicable in your case, but I worked on a car hire problem which supported pickup/drop off across time zones.

Of course, I've not actually answered the original question. Some idea of the data structure/data available might be useful.

Hi All,

I have used (datepart(hour,CR_callstart)) As Hours to group Data by Hours.

What i would like is to group them by Every 30 Minutes. Is there any thing i can use so that
I can get data grouped every hlaf an hour.

At the moment i can get :

Time Revenue
10:00 $100
11:00 $200

With :

Select (datepart(hour,CR_callstart)) As Hours,sum(cost)as Revenue from dbo.Tablename
Group by Hours

But I want to get

Time Revenue
10:00 $75
10:30 $25
11:00 $100
11:30 $100

Please advice.

Thanks

Test the time component (using datepart) for the number of minutes, set a value 0 or 30 and then group by the value. This probably can all me done in 1 select statement.

Thanks so Much for your reply.Its much appreciated.Sorry i am Having trouble to understand it.How do i modify :
(datepart(hour,CR_callstart)) As Hours

Many thanks.

This should do it.

SELECT 
DATEPART(hour,CR_callstart) as hour,
CASE 
	WHEN DATEPART(minute,CR_callstart) between 0 AND 29 THEN 0
	ELSE 30
END as minute,
sum(cost) as revenue
from tablename
group by DATEPART(hour,CR_callstart),
CASE 
	WHEN DATEPART(minute,CR_callstart) between 0 AND 29 THEN 0
	ELSE 30
END

That is Fantastic.Is there any way I can put Hour and Minute in One Column.

Like :

Time
10:00
10:30
11:00
11:30
etcc..

Thanks so much for your time.
