T-SQL (SS2K8) :: Divide Using Formula From Different Table
Jan 23, 2015
I need to evaluate a formula in sql server 2008
Table 1 contains
Entity Value
A 2424053.500000
B 1151425.412500
C 484810.700000
Table 2 contains
Entity Formula
A (2100*(1-0.0668)*24*mday*10)
B (1000*(1-0.0575)*24*mday*10)
C (1260*(1-0.09)*24*mday*10)
Where mday is number of days taken from user
I need to calculate the output of value/formula for each entity can you provide me the query for the same
The datatype for formula column is varchar
I do not have the liberty to use cursors or loops.mday will be a input fromt the user say 'mday = 31' ..i need to divide the value in the first table with the computed value of the formula after replacement

Being one step removed from innumerate, I was wondering whether there was a more elegant way to avoid divide by zero error instead of trudging through a bunch of isnulls.
My intuition tells me that since multiplication looks like repeated addition, that maybe division is repeated subtraction?
If that's true is there a way to finesse divide by zero errors by somehow reframing the statement as multiplication instead of division?
The sql statement that is eating my kishkas is
cast(1.0*(
(ISNULL(a.DNT,0)+ISNULL(a.rex,0)+ISNULL(a.med,0))-(ISNULL(b.dnt,0)+ISNULL(b.rex,0)+ISNULL(b.med,0))/
ISNULL(a.DNT,0)+ISNULL(a.rex,0)+ISNULL(a.med,0)) as decimal(10,4)) TotalLossRatio
Is there a way to nucleate the error by restating the division? My assertion underlying this statement is that the a alias represents a premium paid, so between medical, pharmacy and dental, there MUST BE at least one premium paid, otherwise you wouldn't be here. the b alias is losses, so likewise, between medical, pharmacy and dental, there MUST BE at least one loss (actually, it just occurred to me that maybe there are no losses, but that would be inconceivable, but ill check again)) so that's when it struck me that maybe there's a different way to ask the question that obviates the need to do it by division.

I need to divide amount in joint account. So if joint account has 2 account holders & amount is 35622.15 then one person should have 17811.08 and other person should have 17811.07
If I used below query it just give me 17811.08 for both account holders so when we sum it it's one penny extra.
select cast((35622.15/2) as decimal(15,2))
Is there any way i can achieve this.

I am having 4 Columns Qty decimal(12,3),CF1 Decimal(12,3),CF2 Decimal(12,3),Flag TinyInt.
I want to perform following without using case if it is possible.
When value of Flag is 0 then Qty*(CF2/CF1)
When value of Flag is 1 then Qty
And i Don't want to use any functions like isnull,NullIf,IIF even not union or union all.How to do this calculation without using any function.
Actually i am having more then 100000 rows in table and if i use functions then my index might not be called.,that why want to avoid cases and functions.

I have a column which needs to be 9 digits long. The first four digits are independent from the other digits. The following digits need to be 5 and I have to add leading zeros if they're less than 5. This is an awful design and I'd love to change it but I can't.
SELECT Cg.Fiid,
--Original Formula
SUBSTRING( CONVERT( varchar, Cg.Fiid ),1, 4 ) + RIGHT( '00000' + SUBSTRING( CONVERT(varchar, Cg.Fiid ), 5, 10 ), 5 ),
--My solution
STUFF(Cg.Fiid, 5, 0, REPLICATE('0', 9 - LEN(Cg.Fiid)))
FROM (VALUES(71927),
(498932),
(498934),
(38061278))Cg(Fiid)

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?

Hello Folks,
I'm looking for the group's collective wisdom on the following issue, I'm sure many have been confronted with it.
I'm designing a db for a website that will utilize SQL Server 7. I have few tables that I think will grow very large row wise and that will be written to an read from frequently. I sense that I might be able to get better perfomance out of the system if I split many of these large tables up (row wise) into many smaller tables.
For example, The website that I'm working on has a "MailingAddresses" db table that contains the mailing addresses for the sites users (subscribers and other misc users - 1 record per user, anticipating 70,000+ users). Each user can update their record, and there will be frequent queries to the tables to get addresses for both internal admin use and for display on public webpages.
The website has five distinct sections that are in some sense like five distinct websites. Each user belongs to only one of these sections and they won't migrate between sections. Therefore I'm considering breaking up the one large "MailingAddresses" tables into five smaller tables, one for each section, i.e., "MAddressesSectionA", ..., "MAddressesSectionE".
These tables will have the same fields and constraints. Also of course there would be the same number of reads and writes in total with the five smaller tables as compared to that for the one big table. Also the combined size of the info in the five smaller tables would be the same as that for the one large table.
Though it's going to more of a pain to manage five tables versus one, I have a hunch it might be easier for the dbms to handle reads and writes with five smaller tables than with one large table...
...Of course this is true when queries are mainly respective to users from just one or two of the sections (as might be the case) - the big table then has the overhead of the address records for users in the other sections. BUT is there any benefit with the five smaller tables route when they are all frequently accessed??? Sure each select query has fewer records to go through, but with all five tables in play the dbms has to deal on average with the same amount of info as in the one big table.
What do you folks think, to divide or not to divide the big table(s) up row wise into smaller tables?
I guess the issue is summed up in this question: In general, can a dbms better handle in memory, and more quickly write to and query access - one BIG table with a+b+...+n records, or N smaller tables with a, b,...,n records respectively?
Thanks for the collective wisdom, - Jerry

Hi, Experts,
I have a data table from a old system.

Good day!
What is the syntax on calling a function from a column formula in an MS SQL table.
I created a table, one column's value will be coming from a function. And at the same time, I will pass parameters to the function. How do I do this? Is this correct?
SELECT dbo.FunctionName([Parameter1, Parameter2])
But i can't save the table, "Error validating the formula".
Pls. help
Thanks a lot.

I'm trying extract a column from the table based on certain Conditions: This is for PowerPivot.
Here is the scenario:
I have a table "tb1" with (project_id, month_end_date, monthly_proj_cost ) and table "tb2" with (project_id, key_member_type, key_member, start_dt_active, end_dt_active).
I would like to extract Key_member where key_member_type="PM" and active as of tb1(month_end_date).
Is this possible using DAX ?

How can I apply "Min" formula under a "new measure" (calculated field) within a pivot table under Power pivot 2010?Can see that neither does it allow me to apply "min" formula directly "formula box" nor could find any other option.Intent formula: "=Min(1,sum(a:b))" this isn't allowed so all I can do is "=sum(a:b)".

This seems simple enough but for some reason, my brain isn't working.
I have a lookup table:
Table A: basically dates every 30 days
1/1/2014
2/3/2014
3/3/2014
4/3/2014
I have Table b that has records and dates created assocated with each record
I want all records that fall between the 1st 30 days to have an additional column that indicates 30
union
records with additional column indicating 60 days that fall between the 30 and 60 day
union
records with additional column indicating 90days that fall between the 60 and 90 day mark.
Is there an easy way to do this?

I am trying to move data from one table to the another (staging to real time) in a stored procedure.
There are no indexes or primary keys on the target table and it is still taking ages to execute it (30 minutes approx.). There are no defaults, no constraints as well. There is one identity int column though.
There are some 500000 odd rows in the target table.
I am using the
Insert into..
Select from..
method.

I have 2 identical tables one contains current settings, the other contains all historical settings.I could create a union view to display the current values from table A and all historical values from table B, butthat would also require a Variable to hold the tblid for both select statements.
Q. Can this be done with one joined or conditional select statement?
DECLARE @tblid int = 501
SELECT 1,2,3,4,'CurrentSetting'
FROM TableA ta
WHERE tblid = @tblid
UNION
SELECT 1,2,3,4,'PreviosSetting'
FROM Tableb tb
WHERE tblid = @tblid

In SSMS, I used the ALTER TABLE statement to add a field to a table. No errors are generated and I can verify that the field has been added. Since there are only about 20 records in the table, I use the Edit All Records option to populate that new field. Later, when a job runs using that new field, it fails because the field suddenly does not exist. Sure enough, I check the table and the field is gone. To be more specific, I can add and populate the new field at 2pm. At 6pm, when the job runs, the new field is apparently gone.
I have searched for answers but only have found responses related to the "Prevent saving changes that require table re-creation" in the Tools|Options settings in SSMS. I did uncheck that option, but the problem persists. Based on my searches, the only other alternative is to recreate the table with the new field and move the data from the "old" table to the "new". I got the impression that unchecking that option would mean I would not need to do all this.
I know I have done this type of change before with no issues. What may have changed?I am using SQL Server 2008R2 SP2 on Windows Server 2008R2 SP1.

The actual table only has one row per category (MatrixCat) and will always have only one row per category.
CREATE TABLE #NumVals (MatrixCat VARCHAR(100), MatrixVal VARCHAR(100));

Hi,
In the BI developement, in a matrix i'm trying to avoid division by zero, but even if i test the field before the division, i've got the error everytime.
I put the folowing test condition in the field, but i've got an error.
Ex : iif(Turnover <> 0, Cost/Turnover,0)
But i've got error message when the turnover is 0.
Thanks for your help.
