OP7:      31
MOV1 :  9,02903225806451
MOV2:   8,68387096774194

I have a SQL database table where I defined all data fields decimal(18,2) for these valuesHere is my code ; 

Dim conn As SqlConnection = New SqlConnection("Data Source=SERDARSQLEXPRESS;Initial Catalog=Borsa;Integrated Security=True")
Dim sql As String = "UPDATE StockParametre SET OPT1 = @opt1, OPT2 = @opt2, OPT3 = @opt3, OPT4 = @opt4, OPT5 = @opt5, OPT6 = @opt6, OPT7 = @opt7, MOVY = @mov1, MOVD = @mov2 WHERE Stock = @TickerKod"
Dim cmd As SqlCommand = New SqlCommand(sql, conn)cmd.Parameters.AddWithValue("@opt1", op1)
cmd.Parameters.AddWithValue("@opt2", op2)
cmd.Parameters.AddWithValue("@opt3", op3)
cmd.Parameters.AddWithValue("@opt4", op4)
cmd.Parameters.AddWithValue("@opt5", op5)
cmd.Parameters.AddWithValue("@opt6", op6)
cmd.Parameters.AddWithValue("@opt7", op7)
cmd.Parameters.AddWithValue("@mov1", mov1)
cmd.Parameters.AddWithValue("@mov2", mov2)
cmd.Parameters.AddWithValue("@TickerKod", TickerKod)

conn.Open()
cmd.ExecuteNonQuery()
conn.Close()

When I run these code I have the fallowing error..

The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 3 ("@opt1"): The supplied value is not a valid instance of data type float. Check the source data for invalid values. An example of an invalid value is data of numeric type with scale greater than precision..blabla ...

I tried

cmd.Parameters.AddWithValue("@opt1", FormatNumber(CDec(op1), 2))

but I have the error

Error converting data type nvarchar to numeric.

Thanks

Data Type With Decimal Point For Decimal Values But Not For Whole Integers

Dec 8, 2013

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?

Converting (casting) From Decimal(24,4) To Decimal(21,4) Data Type Problem

Jul 24, 2006

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 have decimal(6,2) defined in a column. If I insert 90.6, it will display 90.60 , 0 becomes .00 .
Is there a way or configuration change so the 0's will on the last will not be showing. And

Thanks in advance.

System.Data.SqlClient.SqlException: Error Converting Data Type Numeric To Decimal.

Aug 31, 2004

Hi There,

I'm using C# to get a value for a DOUBLE precision variable, called "Length", from a textBox using the following line:

Length = Convert.ToDouble( txtLength.Text )

I'm also using the following lines to prepare my stored procedure call:

arParms[9] = new SqlParameter("@Length", SqlDbType.Decimal, 5);
arParms[9].Value = record.Length;

My stored procedure has the following parameter definition:

@Length decimal(9,3)

My problem is that if someone types a value bigger than 999999 in the textbox he will get for sure the following error:

System.Data.SqlClient.SqlException: Error converting data type numeric to decimal.

I don't know how to either make sql or C# to truncate the value or catch the exception to automatically assign 0 to the parameter.

Please Help.
Moshe

Use Decimal Or Varbinary Data Type?

Jul 19, 2007

I need to store 256 bit hash (SHA-2 alogrithmn) in one of the table'sprimary key. I would prefer to use numeric data type rather varcharetc.* Decimal datatype range is -10^38 +1 to 10^38 -1. I can split my 256bit hash into two decimal(38, 0) type columns as composite key* I can store the hash as varbinary. I never used it and don't havemuch understanding in terms of query writing complexities and dealingit through ADO (data type etc.)It would be heavy OLTP type of systems with hash based primary keyused in joins for data retrieval as well.Please provide your expert comments on this.RegardsAnil

Rounding On Decimal Data Type (noob Question)

Feb 22, 2006

Hi all,

I'm trying to update a decimal field with a single decimal number (1.8) the problem i'm having, is that it's rounding the number up (2). I would've thought that a decimal datatype would keep the decimal places correct?

This is quite annoying.. I've been searching around the web for an answer.. To no avail (I'm probably asking the wrong question)

Can someone please point me in the right direction?

Float Type Steals My Decimal Points And Money Type Kills My Query

Mar 28, 2008

Happy Friday!
A while since I have posted a question, and this one is probably real easy.
I am trying to store numeric values from a php form in MSSQL 2000 database. However, the columns are set to float and if the value is 1.00, when entered into the table it is saved as 1

If I change the column type to money, the query fails, with an error message of conversion of datatype varchar to datatype money statement terminated.

anybody know what I need to do? do I need to do something in my query to specify that this is NOT varchar data?

T-SQL (SS2K8) :: Arithmetic Overflow Error Converting Varchar To Data Type Numeric Message When Field Is Decimal

Apr 3, 2014

I am trying to setup an indicator value for an SSRS report to show green and red values on a report, based on the NRESULT value. The problem I am facing is that I have several different CASE statements that have the same logic, and they are processing just fine. NRESULT is a decimal field, so no conversion should be necessary. I do not know why I am getting the "Arithmetic overflow error converting varchar to data type numeric." error message.

Below is the CASE statement where the error is occurring. It is in the part of the ELSE CASE. The first CASE works just fine when the ELSE CASE is commented out. If I also change the ELSE CASE statement to say "else case when LEFT(NRESULT,1) = '-' then '0'", then it processes fine, too, so it has to be something I am missing something in the check on negative values. I do need the two checks, one for positive and one for negative values, to take place.

case when LEFT(NRESULT,1) <> '-' then --This portion, for checking positive values, of the CASE statement works fine.
CASE WHEN LEFT(ROUND(NRESULT,2),4) between 0.00 and 0.49 THEN '2' --Green
ELSE CASE WHEN LEFT(ROUND(NRESULT,2),4) > 0.49 THEN '0' --Red
ELSE '3' --White
END
END
else case when LEFT(NRESULT,1) = '-' then --This portion, for checking negative values, of the CASE statement is producing the conversion error message.

[code]....

I checked the NRESULT field, and there are not any NULL values in there, either.

SQL Problem Updating A Column Of Type DECIMAL(11,4)

Apr 29, 2005

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

Execute SQl Task Return Decimal Type Result

Dec 3, 2007



I am trying to have an Excecute SQL Task return a single row result set executed on SQL Server 2005.


The query in the Execute SQL Task is:
select 735.234, 2454.123

I get a conversion error when trying to assign to SSIS variables of type Double.
I have nothing configured in the "Parameter Mapping" tab.
I have the two SSIS Double variables mapped to the Tesult Name 0 and 1 in the "Result Set" tab

I don't want to use a for loop enumerator since there is a single row returned.

I simply want to assign these two values to SSIS Double variables (double is the closest match)


I can't even hack this by converting the decimals as string and then using DirectCast to convert them to Double.

Thanks for the help

Converting A Data Type Double To A Type Float Using A Data Adapter &&amp; SSCE 3.5

Feb 13, 2008

Hi,

I can populate a dataTable with type double (C#) of say '1055.01' however when I save these to the CE3.5 database using a float(CE3.5) I lose the decimal portion. The 'offending' code is:


this.court0TableAdapter1.Update(this.mycourtsDataSet1.Court0);

this.mycourtsDataSet1.AcceptChanges();

this.court0TableAdapter1.Fill(this.mycourtsDataSet1.Court0);


This did not happen with VS2005/CE3.01.

I have tried changing all references to decimal (or money in CE3.5) without luck.

I'm beginning to think that string may be the way to go!!!!!!!

Can someone shed some light on my problem.

Thanks,

Later:

It's necessary to update the datatable adapter as the 3.01 and 3.5 CE are not compatible.
