T-SQL (SS2K8) :: How To Perform Mathematical Formula Without Using Case
Sep 17, 2014
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 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

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?

Is there an easy way to send back to my C# program the pascal case of a field type? If you get the parameters or columns for a table or procedure the type is in all lowercase (varchar instead of VarChar). But in C#, it is in an enum (SqlDbType) that has the variables as mixed case so you can't compare them and just pass the type. You need to figure out what the case should be - varchar should be VarChar and bigint should be BigInt.

I am using a PIVOT function to obtain the Invoice Values, but they appear in different currencies so need to perform a case function.
But am struggling with the syntax;
This fails a syntax check with
Msg 156, Level 15, State 1, Line 33
Incorrect syntax near the keyword 'Case'.

I am trying to use this logic into a query:
Select P.S,E.S,E.R
from Pack P(nolock)
join Exp E on P.Id=E.O
on E.R is null
case when E.R is not null then ''
else ''
end
where P.s='PLT000044'
I have to query two conditions joining the tables. when E.R is NULL and when E.R is not null. but the value is coming from the join between the 2 tables :P and E.

I have a population split between two vendors. One gets last names between A and R, the other the rest. Now, on a given date vendor 1 gets everybody.
I can accomplish this with a case statement on the upper range (R or Z), but it seems I should be able to do this without testing at all after the turnover date.
A small bit of the code:
declare @get_date datetime = convert(char(10),getdate(),101)
select top 10 pt.pt_id, pt.last_name
fromsmsmir.mir_acct a join smsmir.mir_pt pt on (a.src_sys_id = pt.src_sys_id
and a.pt_id = pt.pt_id
and a.from_file_ind = pt.from_file_ind
[Code] ....
Seems I should be able to not test the last name after the turnover date, but I can't figure out how.

I am a junior dba not a developer. So I'm just trying to get use to write code in T-SQL.
Anyways, I have a table which is dba.dbhakyedek.
Columns are
dbname, username, class_desc, object_name, permission_name, state_desc
I have statement
select case
when class_desc='OBJECT_OR_COLUMN' then 'GRANT '+permission_name+' ON '+'['+left(object_name,3)+'].'+'['+substring(object_name,5,len(object_name))+ '] TO '+username
WHEN class_desc='DATABASE_ROLE' THEN EXEC sp_addrolemember N'object_name', N'MC'
end
from dba.dbhakyedek
where username='MC'
This statement was running successfully until exec sp_addrolemember thing. I just learned that i can't call a sp in select case but i couldnt figure out how to do it.

I have a situation where I want to update a column if and only if it is null.
UPDATE Employee
SET VEmployeeID = CASE WHEN E.VEmployeeID IS NULL
THEN ves.VEmployeeID
END
FROM Employee E
INNER JOIN VEmployeeStaging VES
ON E.EID= VES.EID
But what happens is when I run the procedure every other time I run it, it changes everything to null. The other times it puts the VEmployeeID in.
So what is happening is the times when it is not null (where it is not supposed to do anything) it puts a null in. The next time it works.

I was given the task to come up with a result set based on certain criteria:
Please add one row for each offer code
1) Opt-in rate by offer code: This can be calculated by dividing XXX Inventory with lead / XXX Inventory (A)
The report should read something like below:
Example result set:
Log Date: OfferLetter OfferCode DailyCount
2014-07-20 A XXX Inventory (A) 108
2014-07-20 A XXX Inventory with lead 54
2014-07-20 A XXX Inventory Opt-in Rate: 50%
There are 12 different groupings and OfferLetter A is just one of them.
Below is the code that is written to date:
DECLARE @Start datetime = DATEADD(day, DATEDIFF(day, 0, GETDATE() - 8), 0)
DECLARE @End datetime = DATEADD(day, DATEDIFF(day, 0, GETDATE() - 1) + 1, 0)
DECLARE @Today datetime = DATEADD(day, DATEDIFF(day, 0, GETDATE() - 1), 0);
SELECTDT.OfferCode, DT.OfferCodeDesc
INTO#tempOfferCodes
[Code] ....
The issue I'm having is that the values I need to divide by are in fact, a result set from the CASE statement. It's been a long time since I've done anything like this.

I am trying to use a date comparison in a statement using the year statement as well. Here is what I have:
Case [LastHireDate]
When YEAR([LastHireDate]) < Year(@EndYearlyDate) then '12'
When Month([LastHireDate]) = '1' then '12'
When Month([LastHireDate]) = '2' then '11'
When Month([LastHireDate]) = '3' then '10'
When Month([LastHireDate]) = '4' then '9'
[Code] ....
When I am looking at it [LastHireDate] is showing that red line underneath. The < symbol has a red line and @EndYearlyDate has a red line. I can not seem to get them to clear and am, wondering what I am missing. When I execute the error comes up that it does not like the < sign in there.
Here is the full piece that the Case resides in:
Insert _Test
SELECT
EmpNo,
PersonIdNo,
REPLACE(PersonTaxIdNo,'-',''),
LastName,
FirstName,

I have created a crosstab query using the Pivot statement that returns the expected results. The results look similar to the sample below:
ItemKey Description Aflatoxin Coliform Bacteria E_Coli Fumonisin Melamine Moisture Mold Salmonella Vomitoxin (DON) Yeast
1000 Item1000 1 0 0 1 0 1 0 1 1 0
1024 Item1024 1 0 0 1 0 1 0 1 1 0
135 Item135 1 0 0 1 0 1 0 1 1 0
107 Item107 0 0 0 0 0 1 0 1 1 0
106 Item106 1 0 0 1 0 1 0 1 1 0
I'm using this statement to create the result set:
SELECT ItemKey, Description, Aflatoxin, [Coliform Bacteria], [E_Coli],[Fumonisin],
Melamine,Moisture, Mold, Salmonella, [Vomitoxin (DON)], Yeast
FROM
(SELECT tblInventory.ItemKey, tblInventory.Description,
jctProductClassificationRequiredTest.ProductTestClassID, tlbTestType.TestDescription
[Code] .....
Instead of doing a Count for the Pivot (the count will always be either 0 or 1 due to the design of the table being used), I would like to return an "X" for those records with a count of 1, and return a blank (otherwise null) for those records with a count of 0. So, the result set would look like:
ItemKey Description Aflatoxin Coliform Bacteria E_Coli Fumonisin Melamine Moisture Mold Salmonella Vomitoxin (DON) Yeast
1000 Item1000 X X X X X
1024 Item1024 X X X X X
135 Item135 X X X X X
107 Item107 X X X
106 Item106 X X X X X
I tried using a Case statement within the PIVOT portion, but I either did it incorrectly or it's not possible to do use a Case within the Pivot. Can I easily accomplish this?

What is the equivalent in Transact SQL for VB.net ^ (Exponent Operator)
I have a following equation in VB.net
DotGain = ((1 - 10 ^(D0 - D50)) /(1 - 10 ^ (D0 - D100))) * 100 - 50
where D0, D50 and D100 are decimal variables
Working on creating a SQL UDF where @D0,@D50 and @D100 are transact sql decimal variables
DECLARE @DotGain decimal
DECLARE @D0 decimal
DECLARE @D50 decimal
DECLARE @D100 decimal
SET @D0 = 0.10
SET @D50 = 0.54
SET @D100 = 1.20
SELECT @DotGain = 1 - POWER(10,(@D0 - @D50)) / 1 - POWER(10,(@D0 - @D100)) * 100 - 50
but it is giving me different result in TSQL than VB2005
Can someone correct me?
Thanks in advance.

I've created a sql statement that retrieves number data from various table joins. The number data is then grouped according to various categories. What I need to do is to calculate the average of all the number data in a particular group. How do i go about this? Once calculated, the average needs to be displayed under the data.
For example, the report will list say five numbers (some sets may have more, it depends on how much data is returned based on the query), then under the five numbers, the average is given
2
4
3
6
0
Average: 5
What technique is best? Do I have to calculate the numbers in sql or do I need to configure the report to calculate the average? If so, how? Can someone show me step by step how to do averages for a set of data in the reporting services?
I am completely new to doing reports, I'm just a hobbyist, and I've only used databases to retrieve basic data, but not make manipulations for reports.
Any help will be appreciated.

When I am executing a query that uses a mathematical function on values from 2 tables the query takes much longer than the same query that uses values from 1 table, even though the join remains the same.
Why is this happening?
Is there a way to bypass this problem?
Long query ( values from 2 tables ) :
SELECT
MAX ( ( SIGN ( attribute.keyValue- ( -2027587559 ) ) *SIGN ( attribute.keyValue- ( -2027587559 ) ) -1 ) *-1*data.val ) AS maxVal

Jan 6, 2005
Hello:
I have created an SQL server table in the past on a server that was all case sensative. Over time I found out that switching to a server that is not case sensative still caused my data to become case sensative. I read an article that said you should rebuild your master database then re-create your tables. So after rebuilding the master database, a basic restore would not be sufficient? I would have to go and manually re-create every single table again?
Any suggestions?

We need to install CI database on CS server, and there are some issueswith stored procedures.Database works and have CI collation (Polish_CI_AS). Server hascoresponding CS collation (Polish_CS_AS). Most queries and proceduresworks but some does not :-(We have table Customer which contains field CustomerID.Query "SELECT CUSTOMERID FROM CUSTOMER" works OK regardless ofcharacter case (we have table Customer not CUSTOMER)Following TSQL generate error message that must declare variable @id(in lowercase)DECLARE @ID INT (here @ID in uppercase)SELECT @id=CustomerID FROM Customer WHERE .... (here @id in lowercase)I know @ID is not equal to @id in CS, but database is CI and tablenames Customer and CUSTOMER both works. This does not work forvariables.I suppose it is tempdb collation problem (CS like a server collationis). I tried a property "Identifier Case Sensitivity" for myconnection, but it is read only and have value 8 (Mixed) by default -this is OK I think.DO I MISS SOMETHING ????

I have a view where I'm using a series of conditions within a CASE statement to determine a numeric shipment status for a given row. In addition, I need to bring back the corresponding status text for that shipment status code.
Previously, I had been duplicating the CASE logic for both columns, like so:
Code Block...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE
[logic for condition 1]
THEN 'Condition 1 text'
WHEN [logic for condition 2]
THEN 'Condition 2 text'
WHEN [logic for condition 3]
THEN 'Condition 3 text'
WHEN [logic for condition 4]
THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...
This works, but the logic for each of the case conditions is rather long. I'd like to move away from this for easier code management, plus I imagine that this isn't the best performance-wise.
This is what I'd like to do:
Code Block
...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE shipment_status
WHEN 1 THEN 'Condition 1 text'
WHEN 2 THEN 'Condition 2 text'
WHEN 3 THEN 'Condition 3 text'
WHEN 4 THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...
This runs as a query, however all of the rows now should "Error" as the value for shipment_status_text.
Is what I'm trying to do even currently possible in T-SQL? If not, do you have any other suggestions for how I can accomplish the same result?
Thanks,
Jason
