SQL Server 2008 :: Using Decimal Columns In SUM Function

Jul 21, 2015

Recently I have come across a requirement where i need to design a table.

There are some columns in table like below with DECIMAL Datatype:




Based on my knowledge, i know that values before Floating-Point will not be more than 4 digits.

Now as per MSDN,

Precision => 1 - 9
Storage bytes => 5

so i can create column as:

BldgLengthDECIMAL(6,2) DEFAULT 0


BldgLengthDECIMAL(9,2) DEFAULT 0

Now while reading some articles, i came to know that when we do some kind of operation like SUM Or Avg, on above column then result might be larger than current data type.

So some folks suggested me that i should keep some extra space/digits considering above MATH functions, to avoid an Arithmetic Over Flow error.

So my question is what should be value of DataType for above column ?

SQL Server 2008 :: Limiting To 2 Decimal Points

Aug 31, 2015

The total quantity(sum(woitem.qtytarget) as total) result set is showing more than 6 numbers after the decimal point (example:442.2565485). How can I limit it to 2. (example:442.25)

select wo.num, sysuser.username,sum(woitem.qtytarget) as total
from woitem
join wo
ON wo.id = woitem.woid
Join moitem
on moitem.id = woitem.moitemid
Join mo
ON mo.id = moitem.moid
LEFT JOIN SYSUSER ON mo.userid = sysuser.id
group by sysuser.username, num
ORDER BY CAST( REPLACE( wo.num, ':', '.') as decimal(12, 3))

SQL Server 2008 :: Incorrect Rounding With Decimal?

Oct 17, 2015

My code is rounding my values incorrectly and I'm not sure why. In this example, the numerator is 48 and the denominator is 49 which is .9795 but my SQL is producing 97.0. I would like to result to be 97.9

CONVERT(decimal(4,1), (SUM(CASE Score_CorrectID WHEN 1 THEN 1 ELSE 0 END +
CASE Score_MiniMiranda WHEN 1 THEN 1 ELSE 0 END +
CASE Score_RepAssistance WHEN 1 THEN 1 ELSE 0 END+
CASE Score_Tone WHEN 1 THEN 1 ELSE 0 END +
CASE Score_Consol_Default WHEN 'OK' THEN 1 ELSE 0 END) * 100)
CASE WHEN Score_RepAssistance IS NULL THEN 0 ELSE 1 END+
CASE WHEN Score_Consol_Default IS NULL THEN 0 ELSE 1 END)) AS Avg_Percent_Actions

SQL Server 2012 :: Calculation Based On Count Function To Format As Decimal Value Or Percentage

SQL Server 2008 :: Cross Apply With Parameterized Function?

Sep 9, 2015

I'm unable to reproduce the error. when they upgrade their OS and SQL EXPRESS to a more recent version the error disappears.

The error is: Incorrect syntax near '.'

the query in question resembles this:

Select column1, column2
from Table1 T
cross apply function(t.column4,t.column5) F
where column3 = 'XXXX'

I made sure that the compatibility level is greater than 90 this error is happening on SQL2005 SP2 as well as SQL2008 with SP2 (but not all clients are suffering from the same problem)

Can it be the .net framework? Although the machines had .net framework 3.52.

Can the OS be an issue? The OS' seem to be old, Windows Server 2008 SP2

I've tried to reproduce the error by setting up virtual machines with same OS and SQL but, again, can't reproduce.

SQL Server 2008 :: Joining Two Columns To Same Table?

Aug 17, 2015

I have two tables: "Users" and "Messages".

The Messages table has a "UserFromID" and an "UserToID", indicating a message was sent from a user to a user.

The Users table has a UserID, FirstName, LastName and UserGroup.

Im trying to get all messages sent by or to a user in a specific group, with the First and Last names of the sending and receiving users.

Here is my tables and data:

CREATE TABLE tmp_users (userID INT, GroupID INT, UserName VARCHAR(10), FullName VARCHAR(100))
CREATE TABLE tmp_Messages (aKey INT IDENTITY, FromUserID INT, ToUserID INT, msg VARCHAR(100))
INSERT INTO tmp_users VALUES (1,1,'John','John Smith')
INSERT INTO tmp_users VALUES (2,1,'Jane','Jane Doh')
INSERT INTO tmp_users VALUES (3,1,'Bob','Bob Newheart')


The query Im running so far is wrong, but here it is...

SELECT t.FromUserID, t.ToUserID, t.msg, u.UserName AS UserFrom,
u.GroupID AS FromGroup, u2.UserName AS UserTo, u2.GroupID AS ToGroup
FROM tmp_Messages t
LEFT JOIN (SELECT UserID, GroupID, UserName FROM tmp_users WHERE GroupID = 3) u

[Code] .....

im missing the details of one of the users.I know what the problem is, I just cant figure out how to get this working without using temp tables, which I cant do in the production version.

SQL AVG Function Of A Decimal Column

Jan 13, 2005


Trying to get a dataset. My select statement is "SELECT Com_year,Avg(GPA) FROM Pilot_Stats WHERE com_source = 0 GROUP BY Pilot_Stats.com_year ORDER BY Pilot_Stats.com_year"

Where Com_Year is an integer (ie 1984, 1986, etc)
Where GPA is a decimal (ie 3.4, 3.0, etc)
Where com_source is an integer

This returns this error when I try to fill the dataset:

Decimal byte array constructor requires an array of length four containing valid decimal bytes.

For some reason it's hanging up on Averaging this Decimal column for some reason...

Anyone have an idea why? Thanks for any help!

SQL Server 2008 :: Recursive CTE On Inline Table Valued Function

Jun 22, 2015

I have a recursive CTE on an inline table valued function. I need to set the MAXRECURSION option on the CTE, but SQL Server is complaining with "Incorrect syntax near the keyword 'OPTION'".

It works fine on non-inline function. I couldn't find any documentation indicating this wasn't possible.

I can use the MAXRECURSION option in call to the function

SELECT * FROM MyFunction ()

but that means that the user needs to know the "MyFunction" uses recursive CTE, which defeats the purpose of the abstraction.

SQL Server 2008 :: Exclude Columns When Using Bulk Insert?

Dec 28, 2013

I'm able to successfully import data in a tab-delimited .txt file using the following statement.

BULK INSERT ImportProjectDates FROM "C: mpImportProjectDates.txt"

However, in order to import the text file, I had to add columns to the text file to match the columns that exist in the table. The original file is an export out of another database and contains all but 5 columns from my db.

How would I control which column BULK INSERT actually imports when working with a .txt file? I've tried using a FORMAT FILE, however I kept getting errors which I tracked down to being a case of not using it with a .txt file.

Yes, I could have the DBA add in the missing columns to the query from the other DB to create the columns, however I'd like to know a little bit more about this overall.

SQL Server 2008 :: Append Records With Different Number Of Columns?

Feb 16, 2015

I have a table of Customers & their data in about 20 Columns.

I have another table that has potential Customers with 3 Columns.

I want to append the records from Table 2 onto Table 1 to the Columns with the same names.

I've thought of using UNION ALL or Select Insert but I'm mainly stuck on the most efficient way to do this.

There is also no related field that can be used to join the data as these Customers in table 2 have no Customer ID yet as they're only potential Customers.

Can I just append the 3 columns from Table 2 to the same 3 columns in table 1?

SQL Server 2008 :: Identify Columns And / Or Tables From Records

Mar 3, 2015

I'm using MS SQL Server 2008 and I'm trying to figure out if it is possible to identify what tables / columns contain specific records.

In the example below information generated for the end user, so the column headers (Customer ID, Customer, Address, Phone, Email, Account Balance, Currency) are not necessarily the field names from the relevant tables, they are simply more identifiable headers for the user.

Customer ID CustomerAddress Phone Email Account Balance Currency
js0001 John Smith123 Nowhere Street555-123-456 jsmith@nowhere.com-100 USD
jd2345 Jane Doe 61a Down the road087-963258 jdoe@downthe road.com-2108 GBP
mx9999 Mr X Whoknowsville 147-852369 mrx@whoknows.com0 EUR

In reality the column headers may be called eg (CustID, CustName, CustAdr, CustPh, CustMail, CustACBal, Currency).

As I am not the generator of this report, I would like to know whether or not it is possible to identify the field names and / or what tables they exist in, if I were to used the report info to search for it. For example, could I perhaps find out the field name and table for "jd2345" or for "mrx@whoknows.com", because the Customer ID or Email may not be what the actual fields are called.

I'm not a DB admin and I don't have rights to do a stored procedure on the server. I'm guessing what I want is not so simple to do, but is it possible to do via a query?
