Decimal Values Get Truncated When Using SqlDataReader In C# .net
Feb 17, 2004
The values that are being fetched from the database are not being read as is , when there are decimal values with 10 or more digits after the point, the values are truncated (approximated) to 8 digits
The approximation is not consistent in all the cases
Some times depending on the numbers for example 0.434000001 is truncated to 0.434.
This is happening when i read the values from the sql database using the SqlDataReader.GetValue method into an ArrayList in C# .NET

I'm a newbie to Transact-SQL so I apologize if this is a stupid question. Whenever I try to divide two variables of type int, I get a result where the decimal part is truncated. Here is an example:
ALTER PROCEDURE [dbo].[DIVIDE_TEST]
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
DECLARE
@VAR1 int,
@VAR2 int,
@MYRESULT dec(10,5)
SELECT @VAR1 = 10
SELECT @VAR2 = 3
SELECT @MYRESULT = (@VAR1/@VAR2)
SELECT @MYRESULT
-- @MYRESULT has decimal part truncated, Returned value = 3.00000
END
Any ideas?

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?

Hi gang,
When reading a record from my SQL database for display on a web form, I am checking for null before I assign the value to a TextBox on the form. Here is an example:
// normal database setup code hereSqlDataReader rdr = cmd.ExecuteReader();if (!Convert.IsDBNull(rdr["FirstName"])){ txtFirstName.Text = (string)rdr["FirstName"];}// code here for other record fields
Is this the correct way to do this? Is there a simpler way to do this? I am writing a bunch of database code and I want to do it right...
Thanks,Kevin

I have SQL Server 2012 SSIS. I have Excel source and OLE DB Destination.I have problem with importing CustomerSales column.CustomerSales values like 1000.00,2000.10,3000.30,NotAvailable.So I have decimal values and nvarchar mixed in on Excel column. This is requirement for solution.However SSIS reads only numeric values correctly and nvarchar values are set as Null. Why?
CREATE TABLE [dbo].[Import_CustomerSales](
 [CustomerId] [nvarchar](50) NULL,
 [CustomeName] [nvarchar](50) NULL,
 [CustomerSales] [nvarchar](50) NULL
) ON [PRIMARY]

I have a standard asp.net form and a single database table that I’m trying to pass data into. There are three nvarchar fields of lengths 50, 150, and 2400. Whenever I do an insert or update it truncates all data except for the first character. So if I pass “asdfasdf�, the db field will only receive “a�.
The data going from the form is correct; it gets truncated somewhere after the ExecuteNonQuery() call.
Here is the c# code:
public bool InsertCareer (DataRow row) {
SqlConnection conn = new SqlConnection(connStr);
try {
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = storedProcs[(int)StoredProcedures.Insert];
cmd.Connection = conn;
cmd.Parameters.Add("@pkCareerID", row[0]);
cmd.Parameters.Add("@jobTitle", row[1]);
cmd.Parameters.Add("@postedDate", row[2]);
cmd.Parameters.Add("@submitBy", row[3]);
cmd.Parameters.Add("@department", row[4]);
cmd.Parameters.Add("@description", row[5]);
cmd.Parameters.Add("@intranet", row[6]);
cmd.Parameters.Add("@public", row[7]);
conn.Open();
cmd.ExecuteNonQuery();
return true;
} catch (Exception ex) {
//… stuff
return false;
} finally {
conn.Close();
}
}
This is the sproc code:
CREATE PROCEDURE dbo.zak_CareersIU_sp
@pkCareerID int,
@jobTitle nvarchar,
@postedDate datetime,
@submitBy datetime,
@department nvarchar,
@description nvarchar,
@intranet bit,
@public bit
AS
IF EXISTS (SELECT pkCareerID FROM zak_Careers WHERE pkCareerID=@pkCareerID)
BEGIN
UPDATE zak_Careers SET
jobTitle=@jobTitle,
postedDate=@postedDate,
submitBy=@submitBy,
department=@department,
[description]=@description,
intranet=@intranet,
[public]=@public
WHERE
pkCareerID=@pkCareerID
END
ELSE
BEGIN
INSERT INTO zak_Careers
(jobTitle, postedDate, submitBy, department, [description], intranet, [public])
VALUES
(@jobTitle, @postedDate, @submitBy, @department, @description, @intranet, @public)
END
Please let me know if you have any ideas!
thanks

Hi,
I'm loading millions of rows into a database table. This data contains a lot of dedcimal values of 4 or 6 decimal places somtimes more.
I've found that storing them as floats is inaccurate, and I'm storing as decimals of the appropriate length.
I'm concerned whether this is the right way to do this ?
Can anyone make any suggestions, perhaps an article that I should take a look at ?

Hi All,
I have a table Saleshistory with 89481412 records. I have a field Sales of nvarchar type, all the records in this field are numeric, and the records are with 2 decimal places. I expect all the records to be ending at .00 (for example 5.00,345.00,25.00), but I want to verify if something is for example 5.6 etc.
So in short I want to check if any Salesrecords have more than zero values in the decimal. How can I check this.
Please help.
Thanks,
Zee

Hi
I have an SQL search that is converting two values to type money. I want it to show two digits after the decimal point but am getting inconsistent results. The first value is as follows:
tblInventoryItem.itemcost as originalcost (the column is datatype money)
This displays correctly i.e. 2000.00 or 150.70 etc
The second value is this:
tblInventoryItem.itemcost + tblUpgrades.ItemCost as totalcostincupgr (both columns are datatype money)
But this displays as 2000 or 150.7
How can I get the second value to show two decimal places even when the digits are zeros?
Thanks!

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

Hello all,I'm trying to request a number of URLS (one for each user) from my database, then place each of these results into a separate string variables. I believed that SqlDataReader could do this for me, but I am unsure of how to accomplish this, or if I am walking down the wrong road. The current code is below (the section in question is in bold), please ignore the fact that I'm using MySQL as the commands work in the same way. public partial class main : System.Web.UI.Page{ String UserName; String userId; String HiveConnectionString; String Current_Location; ArrayList Location; public String Location1; public String Location2; public String Location3; //Int32 x = 0; private void Page_Load(object sender, EventArgs e) { if (User.Identity.IsAuthenticated) { UserName = Membership.GetUser().ToString(); userId = Membership.GetUser().ProviderUserKey.ToString(); HiveConnectionString = "Database=hive;Data Source=localhost;User Id=hive_admin;Password=West7647"; using (MySql.Data.MySqlClient.MySqlConnection conn = new MySql.Data.MySqlClient.MySqlConnection(HiveConnectionString)) { // Map Updates MySql.Data.MySqlClient.MySqlCommand Locationcmd = new MySql.Data.MySqlClient.MySqlCommand( "SELECT Location FROM tracker WHERE Location = IsOnline = '1'"); Locationcmd.Parameters.Add("?PKID", MySql.Data.MySqlClient.MySqlDbType.VarChar, 255).Value = userId; Locationcmd.Connection = conn; conn.Open(); MySql.Data.MySqlClient.MySqlDataReader LocationReader = Locationcmd.ExecuteReader(); while (LocationReader.Read()) { Location1 = LocationReader.GetString(0); //Location2 = LocationReader.GetString(1); // This does not work.. } LocationReader.Close(); conn.Close(); // IP Display MySql.Data.MySqlClient.MySqlCommand Checkcmd = new MySql.Data.MySqlClient.MySqlCommand( "SELECT UserName FROM tracker WHERE PKID = ?PKID"); Checkcmd.Parameters.Add("?PKID", MySql.Data.MySqlClient.MySqlDbType.VarChar, 255).Value = userId; Checkcmd.Connection = conn; conn.Open(); object UserExists = Checkcmd.ExecuteScalar(); conn.Close(); if(UserExists == null) { MySql.Data.MySqlClient.MySqlCommand Insertcmd = new MySql.Data.MySqlClient.MySqlCommand( "INSERT INTO tracker (PKID, UserName, IpAddress, IsOnline) VALUES (?PKID, ?Username, ?IpAddress, 1)"); Insertcmd.Parameters.Add("?IpAddress", MySql.Data.MySqlClient.MySqlDbType.VarChar, 15).Value = Request.UserHostAddress; Insertcmd.Parameters.Add("?Username", MySql.Data.MySqlClient.MySqlDbType.VarChar, 255).Value = UserName; Insertcmd.Parameters.Add("?PKID", MySql.Data.MySqlClient.MySqlDbType.VarChar, 255).Value = userId; Insertcmd.Connection = conn; conn.Open(); Insertcmd.ExecuteNonQuery(); conn.Close(); } else { MySql.Data.MySqlClient.MySqlCommand Updatecmd = new MySql.Data.MySqlClient.MySqlCommand( "UPDATE tracker SET IpAddress = ?IpAddress, IsOnline = '1' WHERE UserName = ?Username AND PKID = ?PKID"); Updatecmd.Parameters.Add("?IpAddress", MySql.Data.MySqlClient.MySqlDbType.VarChar, 15).Value = Request.UserHostAddress; Updatecmd.Parameters.Add("?Username", MySql.Data.MySqlClient.MySqlDbType.VarChar, 255).Value = UserName; Updatecmd.Parameters.Add("?PKID", MySql.Data.MySqlClient.MySqlDbType.VarChar, 255).Value = userId; Updatecmd.Connection = conn; conn.Open(); Updatecmd.ExecuteNonQuery(); conn.Close(); } } } } Can anyone advise me on what I should be doing (even if its just a "you should be using this command) if this is not correct? In fact any pointers would be nice !Thanks everyone!

hi, i'm using the following code to generate the value of a column in a database, where the colums value is dependent upon the multiplication of two other cells in the same row. When I execute the statement, it will work fine for whole numbers, but it does not work correctly for decimal values. All columns are of type varchar(50). An exmple.................It just multiplied 200 by 2.50 and returned 600SqlCommand objCmd2 = new SqlCommand("UPDATE Portfolio SET Current_Worth=Current_Price*Number_Of_Shares WHERE Name_Of_Asset LIKE '%'+@Name_Of_Asset+'%'", objConn);objCmd2.Parameters.AddWithValue("@Name_Of_Asset", DropDownList1.SelectedValue);objConn.Open();objCmd2.ExecuteNonQuery();objConn.Close(); Any ideas?

The string column value looks like as below. Each value has a size of 15 withing a string
'2.2020 30 4.0000'
The column value should match with user input as below. The result should show equal when it is compared. Currently, it results not equal since it is a string comparision. The last digit '0' needs to be ignored for decimal values.
'2.202 30 4.0'
I need to handle the decimal values in such a way, if staring value with '.' and last digit is 0 then replace with space ''. So, it should look like
'2 2 2 30 4 ' = '2 2 2 30 4 '
When this string is compared, it results in EQUAL.
I tried the below logic, which even replaces the integer value like 30 to 3 and 3000 to 3 and results in equal which is incorrect.
RTRIM(REPLACE(REPLACE(RT1.rate,'''+@DOT+''','''+@S PACE+'''), '''+@ZERO+''', '''+@SPACE+''')) = '''+REPLACE(REPLACE(@Rate,'.',' '), '0', ' ')+''' '
Ex:'2.2020 300 4.00' = '2.20200 30 4.0'
After replace, string looks like
Ex:'2 2 2 3 4 ' = '2 2 2 3 4 '
It results as EQUAL which is incorrect. I need only decimal value to be replaced not integer.
I am looking for a single string replace logic.

I am importing an excel spreadsheet into a MS SQL database table. When the spreadsheet is finished importing, I am noticing that some values that were brought in resemble something like this 1.41666666666667. Other values may be shorter or only have 1 digit. The problem is another web application that pulls this data for use in online forms only allows up to 2 digits. How can I round all of the numbers like the above to 2 decimals and replace the existing values?
I know there is the rounding function that could be used like so:
SELECT ROUND ([Hrs Total 2],2)
FROM AnnualClassifiedPAFs
How do I then take that rounded value and insert it back into the records?

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,

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

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!

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

Hey All,
I have come across a situation with two tables, they are dynamic and the user can add and edit values in the tables so I need to build a dynamic display control. It is all based around an FAQ system I have built. The user can create new FAQ categories (that is one table) then create a new FAQ Question & Answer (that is the second table). The tables are linked by the category id. So now I am trying to display the FAQ section like so.
CATEGORY NAME
QuestionAnswerQuestionAnswerCATEGORY NAME
QuestionAnswerQuestionAnswerCATEGORY NAME
QuestionAnswerQuestionAnswer
So my idea was to run a loop within a loop. First loop the category name, then within the category name, loop a second time to grab all of the questions & answers within the category id captured from the first loops sql select statement, then proceed to loop the category name again and of course repeat the process until all loops are completed. However I am getting, and I kinda figured I would get an error about my SQLDataReader. Bellow is my code maybe some type of edit or different recommendation is needed. Any help will do, thanks!Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'--- Database Connection ---Dim sConnStr As String = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString
