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.

Hi,How to find the list of SQL math functions in SQL Server 2005?ThanksKai
View 2 Replies View RelatedI'm not a professional dba or dbd, but I'm proficient in the basics ofdatabase design and sql.

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). This will log how many salesreps worked a particular day. 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?

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 implement this pseudocode in a SQL stored proc?
In my stored proc, intDS and intSS are the corresponding locally declared variables: @cnt1 and @cnt2 (both are int's).
double intRating = 0;
if (intDS != 0)
intRating = ((intDS - intSS ) / intDS) * 100;
if (intRating < 0)
intRating = 0;
intRating = RoundUpDown(intRating);
The last line should round up or downd the decimal value, if it has decimals, to the next round/whole number... e.g. 28.4352635 to 28.
Thank you!
I realize this gets into business logic, but a DB based solution might be best. Possibly some pre-calculated measurement tables.
Business problem: Creating a cut list for a window covering (blinds) system. It's preferably a fast calculation I could execute while the user awaits "order confirmation and pricing". A .5 second delay per order would be acceptable.
An order can have unlimited number of line items, but typically between 1 and 20 (number of windows in a single house).
(For this problem) the raw material is man-made, and therefore is always the same length for a particular pattern/color (take 12' for this example; we stock patterns in 9', 12', or 16' but it's always the same for a given pattern/color). I need to tell the cutters how to use the rawmaterial with minimal waste. Note: The saw blade takes 1/16th inch.
For each line item; I have pre-calculated the exact cut size and number of slats. Measurements are in inches at 1/8 (.125) inch increments. The length of raw material length we stock for this pattern is an easy link.
The goal is to average less than 6 inches waste per 12' piece of raw material.
Example order:
5 line items for pattern/color FAUX/white, stocked in 12' lengths.
Line 1: 34 slats at 35.125 inches.
Line 2: 36 slats at 36.875 inches.
Line 3: 50 slats at 42 inches.
Line 4: 55 slats at 70 inches.
Line 5: 52 slats at 30 inches.
The resulting cut-list-workorder would evaluate all lines together and tell them how many 12' slats to pull and how to cut them with minimal material waste.
My question:
I'm left wondering if a database style pre-populated answer list (or some other database based solution) might be a lot faster and simpler than some chess-style complex trial-and-error array based VB algorythm (that I haven't even begun to imagine how to write). If so; how would it look?
In addition; the cutters get something like $10/hr so we can't make it too complex. I'd rather waste a little material and avoid undue confusion, but not much. With $5+ million in this material per year, excess waste can really add up. Imagine the difference between 12% and 15% waste. It's an area worth investing in.
Sorry; I know it's not a simple question. Someone might find it interesting enough to solve, or at least provide hope for a DB solution. At present; I just can't imagine it.

I'm trying to figure out marketshares for "preferred" products. I have a table put together by hospital and month of medication use with the totals of each drug dispensed in columns as well.
(example table below)
Hospital Month Drug A Drug B Drug C Drug D
A 7 5 10 58 73
B 7 NULL 26 98 43
etc.
** Drug C and Drug D are the preferred drugs
I'm getting correct preferred % in all cases except when a value is NULL (result is NULL). I'm using an aggregate (sum), which should ignore NULLs, but it ignores NULLs within a column, and not ignoring across columns. I've tried setting concat_null_yields_null off and I'm still getting NULL (since I'm using the plus sign).
This is my admittedly confused select statement, suspect this is where my problem lies (problems with saying "sum", but using "+" as well?):
select a.Hospital,a.month,convert(float,sum(c.Drug_C+d.Drug_D))/convert(float,sum(a.Drug_A+b.Drug_B+
c.Drug_C+d.Drug_D)) as preferred_share

I want to evaluate a math formula inside of a function, so I can't use dynamic SQL.
I found that the query on an XML-variable with a literal works well.
DECLARE @sParsedFormula varchar(200);
DECLARE @xFormula xml;
SET @xFormula = '';
SET @sParsedFormula = '1+2';
SELECT @xFormula.query('3+3') , @xFormula.query('sql:variable("@sParsedFormula")')Output (1st value is correctly evaluated, 2nd not):
"6", "1+2"
I can't directly pass @sParsedFormula to the query otherwise I get "The argument 1 of the XML data type method "query" must be a string literal". What is the correct XQuery-syntax to evaluate the SQL:variable?
Using a reporting services model/report builder we have two related tables:
- Fundings, (parent)
- Draws, (child)
Report Builder reports that subtract "Total Fundings.Amount", (which is SUM(FundingAmount)) from "Total Draw Amount", (which is SUM(DrawAmount)) to get a balance work as expected except when there are no Draw rows, in which case a NULL is returned. Obviously we want to convert NULL values of "Total Draw Amount" to zero so that when subtracted from "Total Fundings.Amount" the correct value is displayed. I've searched for a function similar to COALESCE (Transact-SQL) in report builder but found nothing.
Can anybody help me with this?
