SQL AVG Function Of A Decimal Column
Jan 13, 2005
Hi,
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!

Hello Sir
I am working on a Teacher Evaluation Project. In my database I store results from 1-5 as evaluation indicators. I apply AVG() function on the result column. The result of the query is in integer values (i.e) 4, 3 2 or 5. I want the resutl up to two decimal places. How can i write the query to get the result in decimal form?

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:
BldgLength
BldgHeight
BldgWeight
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
OR
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 ?

I have been given some data from a Mainframe (AS400?) which has some fields coded in Packed Decimal. I have been able to load the data into a SQL2005 database table, but I now need to convert the Packed Decimal data in the binary(6) field to the appropriate integer (or float) value.
The field contains values such as the following:-
0x20202020200C
0x202020022025
0x20202020DFFA
I don't know how to interpret these. Has anyone got a function that can do this for me?
I've read several articles online that explain how packed decimal works, but none tell me how to interpret the last of my three examples. Can you help?
Thanks!

I'm trying to get a calculation based on count(*) to format as a decimal value or percentage.
I keep getting 0s for the solution_rejected_percent column. How can I format this like 0.50 (for 50%)?
select mi.id, count(*) as cnt,
count(*) + 1 as cntplusone,
cast(count(*) / (count(*) + 1) as numeric(10,2)) as solution_rejected_percent
from metric_instance mi
INNER JOIN incident i
on i.number = mi.id
WHERE mi.definition = 'Solution Rejected'
AND i.state = 'Closed'
group by mi.id
id cnt cntplusone solution_rejected_percent
-------------------------------------------------- ----------- ----------- ---------------------------------------
INC011256 1 2 0.00
INC011290 1 2 0.00
INC011291 1 2 0.00
INC011522 1 2 0.00
INC011799 2 3 0.00

I want to change decimal precision dynamically without rounding value
For example
10.56788 value for 2 decimal precision is 10.56.
10.56788 value for 3 decimal precision is 10.567.
---CASE 1 without dynamic parameter---------
DECLARE @DECIMALVALUE AS tinyint
SELECT CONVERT(DECIMAL(10,2),500000.565356) As Amount
[Code] ....
I am getting error as follows......
Msg 102, Level 15, State 1, Line 3

Hi Guys,
I want to find out if a ceratin column has values with decimal figures populated? for example say column A has values
10.00
20.00
30.00
50.01
in this case the query should let me know that there is one figure (50.01) with a actual decimal value. So the results of the query should be 1 (since one record has decimal figures <>.00)
Cananyone help

This problem is strictly an SQL problem, and I am about to lose my mind over it. I have a table named Inventory that has a column named PartialQty which is of type DECIMAL(11,4). I have shortened my query for simplicity, but here it is.
DECLARE @pqty1 DECIMAL(11,4)
SELECT @pqty1 = PartialQty FROM Inventory WHERE InventoryID = @invIDPRINT @pqty1 UPDATE Inventory SET PartialQty = 6.5513 WHERE InventoryID = @invID
SELECT @pqty1 = PartialQty FROM Inventory WHERE InventoryID = @invIDPRINT @pqty1
Before this query is ran, the value in PartialQty is 1.2345. If I run this 2 times in a row, this is the output I get:
RUN 1:
1.2345
(1 row(s) affected)
(1 row(s) affected)
(1 row(s) affected)
(1 row(s) affected)
6.0000
RUN 2:
6.0000
(1 row(s) affected)
6.5513
I don't understand 2 things. One is why the first run displays (1 row(s) affected) 4 times even though there is only one record with that InventoryID.
And the other thing I don't understand is why the first time I run it, it loses all of the values after the decimal point.
Please help,
Scott

How do I limit the decimal points in a computed column. SSE 2005 seems to override the precision and scale I set in either GUI or by creating the table by query.
Thanks in advance for helping.

On table TABLENAME, I have increased the size of column C to decimal(38, 14); maximum size and an excessive amount of precision.
If I do a
SELECT MAX(CONVERT(DECIMAL(7,2), A) / B) FROM TABLENAME
SELECT MIN(CONVERT(DECIMAL(7,2), A) / B) FROM TABLENAME
I get 3.0000000000000 for the MAX and 0.1000000000000 for the MIN value, yet if I update
UPDATE TABLENAME SET C = CONVERT(DECIMAL(7,2), A) / B WHERE B <> 0
Msg 8115, Level 16, State 8, Line 1
Arithmetic overflow error converting numeric to data type numeric.
The statement has been terminated.
Obviously I have obscured the column names and table name, but I am puzzled as to why values in the range 0.1 to 3.0 should give an overflow error.
I am using SQL2005 SP2

We are importing Flat file data from our Mainframe system. We have a lot of money amounts coming in, but the mainframe does not store the decimals in the flat file. So for example a row in the file might look like this:
+0000007894-0000000563
Where the first value is $78.94 and the second value is -$5.63
Is there anyway to have the Flat file connection manager put in the decimal place for me, or do i have to create derived columns for each column and divide it by 100? There like 50-100 columns per file, so i'm looking for a better, quicker way.
Thanks in advance.

I am working with a legacy SQL server database from SQL Server 2000. I noticed that in some places that they use decimal data types, that I would normally think they should be using integer data types. Why is this does anyone know?
Example: AutomobileTypeId (PK, decimal(10,0), not null)

I am creating a table on SQL Server. One of the columns in this new table contains whole integer as wells as decimal values (i.e. 4500 0.9876). I currently have this column defined as Decimal(12,4). This adds 4 digits after the decimal point to the whole integers. Is there a data type that will have the decimal point only for decimal values and no decimal point for the whole integers?

Hello.
My database stores the decimals in Spanish format; "," (comma) as decimal separator.
I need to convert decimal nvarchar values (with comma as decimal separator) as a decimal or int.
Any Case using CAST or CONVERT, For Decimal or Int gives me the following error:
Error converting data type varchar to numeric
Any knows how to resolve.
Or any knows any parameter or similar, to indicate to the Cast or Convert, that the decimal separator is a comma instead a dot.

Hello!
I would like to cast (convert) data type decimal(24,4) to
decimal(21,4). I could not do this using standard casting function
CAST(@variable as decimal(21,4)) or CONVERT(decimal(21,4),@variable)
because of the following error: "Arithmetic overflow error converting
numeric to data type numeric." Is that because of possible loss of the
value?
Thanks for giving me any advice,
Ziga

I wanted to convert a dataset from vb.net (2.0) to an .XLS file, by MS Jet. My national standard is using decimal commas, not decimal points for numbers signing the beginning of decimal places.
But the MS Jet Engine uses decimal point,in default. Therefore, in the Excel file only string formatted cells can welcome this data, not number formatted.
How can I solve or get around this problem? (with jet if it possible)

Hi all,
I am designing some reports for a German branch of my company and need to replace decimal point with a comma and the thousand comma seperator with a decimal point.
e.g.
‚¬1,500,123.00 to ‚¬1.500.123,00
Is there a property that I can change in the report designer to allow this to happen or is this something I need to convert in a Stored Proc.
Any help would be much appreciated
Thanks!

I need to store decimal values: decimal(20,15) in my SQL Server 2005 database.
I load data from flat file, convert it using Data Conversion Task to decimal(with scale: 15) and try to save it using OLE DB Destination.
It works fine for 4 digits after the decimal (like 1.1234), but always failes for more than 4 digits (1.12345).
Is the decimal limited to scale 4 ???
Thank you for your help!

Hi,
I am having a file in which amount fields are given in a Packed Decimal format. Can anyone suggest me how I can read this data element from the file and convert it into SQL decimal datatype.
File is a fixed length. All the amount fields are given in Packed Decimal Format and rest of the fields are given in text format.
How can i identify and convert only those packed decimals using SQL/.Net.
Example : a row in a file that has some packed decimals
