Decimal.MinValue Throw OverflowException

Apr 19, 2007

I'm using Decimal.MinValue in SqlParameter( SqlDbType.Decimal ) to execute a stored procedure.

But, I receive this stack trace exception:

 System.OverflowException: Conversion overflows.
   at System.Data.SqlTypes.SqlDecimal.ToDecimal()
   at System.Data.SqlTypes.SqlDecimal.get_Value()
   at System.Data.SqlClient.TdsParser.AdjustDecimalScale(Decimal value, Int32 newScale)
   at System.Data.SqlClient.TdsParser.TdsExecuteRPC(_SqlRPC[] rpcArray, Int32 timeout, Boolean inSchema, SqlNotificationRequest notificationRequest, TdsParserStateObject stateObj)

   at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe)
   at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()

I have changed Decimal.MinValue to Decimal.Zero to resolve my trouble. But, Why Decimal.MinValue throw OverflowException? Isn't Decimal.MinValue  valid SqlDbType.Decimal type?

INSERT Does Not Throw Error, What Do I Need To Do

Feb 5, 2008

I am using SQL Server 2005 Express and one of the fields in my table has the UNIQUE constraint.  When I try inserting a duplicate nothing gets inserted in the table, but no error is thrown.  Where can I do a check for this?  I would like to popup a message to the user indicating that the insert failed to the the unique constraint.  I have configured the SQLDataSource with Insert/Update/Delete so the actual insert is done behind the scenes. Thanks in advanceEric

Incorrect Syntax Near Throw

Aug 12, 2013

I have what looks to be a very simple Stored Procedure as follows:

CREATE PROCEDURE SOE_OFMUpdateStatus_v1  
@sOrderNumber
numeric(7,0),
@sOrderType
char,
@sSupCode
char,
@sOrderStatus
varchar(15),

[code]...

When I execute the SQL Script in SQL Server Management Studio, everything is just fine.  I have included this SP in a VS 2012 Database Project, and when I build, I get the error 'Incorrect Syntax near Throw'.  The Database project is set to SQL 2012.  I did try putting a ';' in front of the THROW as has been suggested on other threads. is this a case where we will have to abandon use of VS 2012 Database integration?

How Can I Throw A Custom Error Code?

Jun 26, 2006

I'm trying to run a DTS package, and cant find an easy direct way to run it.  It seems like the easiest solution would be to throw a custom error- then the server notices the error and runs a  custom job, and the custom job runs the DTS.  This is a roundabout way, but seems like it would be the simplest solution.Anyways, how do I throw the error in my code?  Do I just write a throw 3829 statement?  Also maybe this is a very bad way to do this- any suggestions?

Export To Excel Throw WrapperReportRenderingException

Jan 23, 2008



I have a report runs without any problem (Url access) and export to other format also without any problem.
Only when I export the same report to Excel, the following error occurs in the reportserver log and its throws an error on screen.

I have found out it is down to a table grouping on a data field.

The report conatins a list and the list has a details group, which grouping the data by week.
A table is sit inside the list to report the data.
Within the table, there is a group list which is grouped by a field from the dataset.

I have the actual RDL and RDL.data file if anyone like the challenge.

Here is the error from the report server log:

Legacy Database Uses Decimal Data Types.--&> AutomobileTypeId (PK, Decimal(10,0), Not Null) Why Not Integers Instead ?

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?

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?

Cast Or Convert Nvarchar With Comma As Decimal Separator To Decimal

Apr 29, 2008

Any Case using CAST or CONVERT, For Decimal or Int gives me the following error:

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.

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,

SQL Server 2014 :: Capture THROW For Logging

Aug 14, 2015

Is it possible to capture the contents of THROW within a CATCH into a variable so that it can be written to a logging table?

I can capture ERROR_MESSAGE() to a variable but unfortunately it only writes the last error rather than the previous one that is informational.

I realize that THROW can be multiple lines so it may not be possible to do through TSQL but thought I should ask.

Missing Dataflow Task? ( Throw Execption)

Dec 27, 2007



Maybe I am mistaken ( most likely ). But I am missing a dataflow task, which would do something similar like Throw Execption.

The project I am currently working on needs to validate a lot of different data. And sometimes incorrect data ( corrupted, incomplete or unexepected ) is coming from the source system. In case of this I need to trigger an error and discard the complete row or batch depending on the situation.

For example:
In our source system we have some flag fields. And certain combinations of flags are not logical (business rules) but the system allows data to be inputted in this unlogical ways. And because we are creating the system I am expecting some combinations flags which are allowed but not properly defined in the specification.

So when I use a conditional split, I want the default output to trigger an error instead of an output.

How Can I Use The Decimal Comma Instead Of Decimal Point For Numbers In Jet Engine?

Sep 19, 2007



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)

Converting Decimal Point To Decimal Comma

Nov 30, 2007

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

SQL Server 2012 :: Use Unique Custom Error Numbers For THROW Statements?

Apr 20, 2015

My team is starting to implement error handling in our sprocs. One question we have is whether or not to use unique error numbers for custom errors (ie Errors we throw after doing some sort of validity check, not SQL Server errors). For example, we might check the value of a parameter and then throw an error that says "Parameter State_Date must be less than today, please retry".

We are using SQL Server 2012 and will be using the THROW statement, not RAISERROR, so we don't HAVE to put the numbers in sys.messages. Also, we are going to log the errors in a table, along with the error message, sproc name, line number, etc.

Is it useful to maintain a custom list of error numbers and messages? Or is it just as useful to use one standard error number and add a custom error message (which we can then search for in our code, or use the sproc name & line number we logged)? And if it is worth maintaining a list of numbers plus messages, should we go ahead and put them in sys.messages?

DTSX Package Continues To Throw Errors When Working With Large Dataset.

Jun 7, 2006

I have a dataset that is between 40-50K records that has to go through a process that is pre-defined. SSIS works just fine with the smaller sets even up to 20K but this job keeps blowing up saying something along the lines of cannot write to recordset destination. Does this make sense to anyone? The sever is a 2 processor with 2GB of ram. Physical memory usage spikes to about 1.6GB during the run but the processor never really gets above 30% usage. Does this product just not scale yet?

Decimal Limited To 4 Digits To Right Of Decimal?

Jun 18, 2007





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!

T-SQL ROUND(decimal, Int) Vs C# Round(Decimal, Int32)

Jan 30, 2006

Anybody noticed that SQL Server rounds up if the value is half waybetween two rounded values, but C#'s Decimal.Round(Decimal,Int32)rounds to nearest even number?[color=blue]>From MSDN: "When d is exactly halfway between two rounded values, the[/color]result is the rounded value that has an even digit in the far rightdecimal position. For example, when rounded to two decimals, the value2.345 becomes 2.34 and the value 2.355 becomes 2.36. This process isknown as rounding toward even, or rounding to nearest."I perform the same calculation sometimes on the web server in C# andsometimes at the database in T-SQL, but want to get the same resultfrom both calculations. Could anybody offer any strategies for dealingwith this?Thanks ~ Matt

I tried changing it in the table design after the import and nothing changed.
Then i tried re-writing the query for insertiing the values, where i changed varchar(11) to numeric (11,2) but i got an error. "Error converting data type nvarchar to numeric."

Any suggestions on resolving this glitch ??

Decimal Problem

Dec 18, 2006

Hi guys,I've got a table with one of the columns 'ConversionRate' declared as decimal. The value for this column is defined as 1.45. In my vb file, I tried to retrieve the value using a SqlParameter as shown below:myConversionRate = Me.SqlCommand.Parameters.Add(Sql.StoredProcParameter.ConversionRate, SqlDbType.Decimal)myConversionRate.Direction = ParameterDirection.Output  which will access the following query in my stored proc:  ALTER PROCEDURE dbo.Charge
@PConversionRate DECIMAL = 0 OUTPUT
AS
SELECT @PConversionRate = ConversionRate,
FROM TblCharge
 For some reasons, the value returned is always 1 instead of 1.45. Anyone experienced this problem before and knows how to resolve it? Thanks in advance.

2 Decimal Places On Sql AVG ()

May 31, 2007

Hi,
I am trying to get my string to 2 decimal places...
Here is the code:string sumSQL = "SELECT CONVERT (float,sum(callTime)/count(callTime)) as CAVG FROM leads where agent = '" + agent + "' and " + dates.Text;
 SqlCommand sumCMD = new SqlCommand(sumSQL, conn2);
object null1 = sumCMD.ExecuteScalar();if (null1 != null)
{string avgS = sumCMD.ExecuteScalar().ToString();Response.Write(avgS + "<br>" + "</td></tr><tr>");
}
 
Any Help appreciated...
Doug
