thanks in advance!
The value in the table of one DB is 17869 sq. ft. Now to insert this value in a new table of other database the reporting basis is 1000 i.e I need to do 17869/1000 = 17.8 so I have to take the value as 18. Another thing to be kept in mind is the value in the new table should have leading Zeroes. If the value is 18 it should be displayed as 0000018 ( data type in new table is Varchar(7) and in old table char (9) ). What can be the best way to implement this??

How do i update a sql table so that the result cannot be less than zero?for example, lets say I have the column "Number"I have a sql update statement that subtracts 1 from number:"Update oTable SET Number = (Number - 1)"Except that Number cannot be less than zero. Is there a way to do this in sql statement so that I don't have to have a select statement just to check that Number is greater than zero to begin with? Thanks
View 4 Replies View RelatedHello everyone:
I have a database for one of my websites, a picture rating site. Anyways, right now there are quicte a few tables, and I was wondering how to give the server a break and was wondering if this was possible:
Basicly I have a members table, and a votes table. Members will rate other users pcitures on a scale of one to ten, then the votes will be inserted into the votes table. The only problem with this is that calcuating all the votes a user has can put a straing on the server. I was wondering if it would be possible to create a math column in the members table that would automaticly figure out the users average and having it stored in a field in the members table, so all I would have to do is query the members average located in the mebers table, rather than tallying all the votes in the votes table for each member.
Hope this makes sense, a tutorial or any suggestions would be great!
Thanks
I have 2 questions.
1) Lets say we have a table
CREATE TABLE TEST
(
N INT
)
These table have 10 records - the numbers from 1 to 10.
I need 1 query ONLY which will update the table and make it with 100 records - the numbers from 1 to 100.
2) How with 1 query ONLY i have select only the prime numbers
I have some dates stored in a field named "visit"
In a select they show as the format:
2005-07-28 10:45:00.000
So I need to write a query that will select Visits that are more than 90 days old. I thought it might be something simple like:
Select * from patientVisit where ((getdate())-Visit>90)
But that is pulling all visits not just 90 day old ones.
How do I pull the current date/time and compute the cutoff date time that would be 90 days prior for my selection Where clause?
Thanks
I need to create a new column where I subtract one column by another.

Does anyone know if there is such a quary that can be written which would add up(or any math functions) a line of cells (on different rows) similar to that of working with a excel document?
If so please steer me towards the correct syntax for this.

Hi,
I have a column coming from DB2. It is the time is stored as 6 decimals of a second. So the value I got coming in is 44846(DT_I8), which needs to be divided by 60 to get minutes (747 minutes remainder 26 seconds). Then divide 747 by 60 to get 12 hours remainder 27 minutes. Thus the time is 12:27:26.
I have got a dervived column doing (DT_R8)(SUBSTRING((DT_WSTR,8)PSCCLOGTIM,1,5)) / 60 but the answer I am getting out is 747.433333. Close, but not close enough. Now I assume my problem has something to do with the Math being done on actual numbers not Time based numbers.
Anyone got any ideas on where I am going wrong and what the expression should look like?
I have been trying to make a database that counts up and down votes (like eBay ratings or reddit votes). I think (hope) I have got the database design right.
I know that you can perform math functions in SQL, but I want to use two COUNT()s from the same table and subtract one (the down votes) from the other (the up votes).
I have been learning ASP.NET 2.0 and it's going well, but I really need help with this. I asked a question on this forum before and the answers were great and really helpful.
If anyone can help that would be great. Thank you.
Jack.
I need to perform some division on the results of two alias columns that perform counts in a query. What is the best way to do this?
View 7 Replies View RelatedThe business rule is, the sales manager is commissioned on the avg. numberof appointments set up per salesrep per day during the month.I have 2 tables: The UserLog table records only 1 entry per day per user(salesrep).

Thesecond table logs any appointments set up.UserLog: ID, UserName, EnteredTimeAppointment: ApptID, EnteredTime, ApptDateI figured that, for a given date ranged, I could1. sum the number of appointments2. sum the number of days worked2. sum the salesreps / number of days = avg number of salesreps per day3. number of appointments / avg number of salesreps per day = avg numberof appointments per sales repBut this logic is flawed. If I average out every day and then take anaverage of this daily average, I get a different result. Any ideas on howto best solve this problem?Thanks.

I would like to have an either a sql statement (1st) or a stored procedure (2nd) that would give me the percent correct for each student on the test.
In Access I could cheat and use this:
Code BlockSELECT Students.StudentName,
Count(Students.StudentName) AS TotalCorrect,
(SELECT Count(QuizMaster.ID) FROM QuizMaster;) AS TotalQuestions,
([TotalCorrect])/([TotalQuestions])*100 AS PercentValue
FROM (Answers INNER JOIN Students
ON Answers.StudentID = Students.ID)
INNER JOIN QuizMaster
ON (Answers.Answer = QuizMaster.Answer)
AND (Answers.QuestionID = QuizMaster.ID)
GROUP BY Students.StudentName
ORDER BY Students.StudentName, PercentValue;
Which is composed of the following...
Code Block
SELECT Students.StudentName,
Count(Students.StudentName) AS TotalCorrect
FROM (Answers INNER JOIN Students
ON Answers.StudentID = Students.ID)
INNER JOIN QuizMaster
ON (Answers.Answer = QuizMaster.Answer)
AND (Answers.QuestionID = QuizMaster.ID)
GROUP BY Students.StudentName;
SELECT Count(QuizMaster.ID) AS TotalQuestions
FROM QuizMaster;
([TotalCorrect])/([TotalQuestions])*100 AS PercentValue
But... that wont fly in SQL Server...What would work without using temp tables?
What would be the EASIEST way to do this?
Another way someone suggested is:
Code BlockCREATE PROCEDURE GetStudentGradeByID @StudentID Integer
AS
BEGIN
DECLARE @TotalQuestionsAsked as Integer;
DECLARE @StudentName as VarChar(50);
DECLARE @QuestionsCorrect as Integer;
DECLARE @PercentCorrect as Float;
set @TotalQuestionsAsked = select COUNT(*)FROM QuizMaster;
set @StudentName = select StudentName from Students where ID = @StudentID;
set @QuestionsCorrect = select count(Answers.ID) from Answers LEFT JOIN QuizMaster on Answers.QuestionID = QuizMaster.ID where StudentID = @StudentID AND QuizMaster.Answer = Answers.Answer;
set @PercentCorrect = (CAST (@QuestionsCorrect AS FLOAT) / CAST (@TotalQuestionsAsked AS FLOAT)) * 100.0;
select @QuestionsCorrect as TotalCorrect, @StudentName as Student, @TotalQuestionsAsked as NumQuestions, @PercentCorrect as CorrectPct;
END
But I need this as a datasource for a datagrid that would show all students etc... so using a parameter isn't really what I want.
So... could a stored procedure work for this?

I hope it's considered appropriate to post a SQL query question here; it's not I'll gladly post this question elsewhere. That having been said, I've run into a simple but quite tricky SQL query and was wondering if the community might be able to help. Here's what's going on:
I have a "Documents" table. Let's call it DI have a "Benefits" table. Let's call it B.There is a many-to-many relationship between D and B so I have a third table to store the relationships. Let's call that table BD.
When I create a document it creates a row in D. Let's call that D1, D2...DN. When I create a benefit it creates a row in B. Let's call that B1, B2...BN
When I associate a document to a paritcular benefit, let's say that if D1 and B2 are associated, that I created row B2-D1 in my BD table. Now here's what my challenge is. Suppose I have these entries in my tables:
D: D1, D2, D3B: B1, B2, B3
Table BD:B1-D1B2-D1B2-D2
When the user goes to add documents to benefit B1, I want to show the user only documents that are not yet added to B1. In this case, I want to show the user D2 and D3 but not D1 since that one's already added. How do I write a SQL query to do this?
Here's what I've been using, but it shows too many results (e.g. included D1, D2, D3)
SELECT D.*, BD.*FROM Documents AS d LEFT JOIN rel_BenefitsDocuments AS bd ON d.doc_id = bd.doc_idWHERE (benefit_id <> @benefit_id OR benefit_id IS NULL)
Any thoughts?

WHERE
dbo.fn_Calc(t.column1) > @treshold
I can't think of a way to get rid of the function call in the WHERE clause.
Is this actualy a problem ?
I mean does realy the function fn_Calc execute 2 times in this statement and isn't this a performance issue then?

This should be easy, I'm just having a brainfart at the moment, can't remember how to do this:
Say I have a bunch of records in a table, with an ID field as Key. I want to return the count of times each ID shows up, so for the following example data:
Code:
-----
| ID |
-----
| 1 |
| 2 |
| 1 |
| 4 |
| 1 |
| 4 |
------
Would return something like:
Code:
----------------
| ID | Count |
----------------
| 1 | 3 |
| 2 | 1 |
| 4 | 2 |
-----------------
This should be obvious but for some reason I can't see it.
When this is done I'm going to join in another table to get a name based on the ID with the highest count. I believe it's faster to do a TOP 1 here rather than after the join, but I want to verify that while I'm at it also.
