SqlCeException：表达式评估导致溢出

Question

There are other questions with similar sounding titles, but my case appears to be unique, so here goes:

This problem seems to be centered on using Decimal values in my table. If I create a table and leave out the Precision and Scale parameters, the table creates but all of my data is inserted as an integer value. If I create a table and specify the Precision and Scale parameters, I get the exception thrown below my SQL Statements.

Here is my Create Table statement:

CREATE TABLE RMCoil 
(
    ID int IDENTITY (100,1) PRIMARY KEY
,   Modified DateTime NOT NULL
,   [Type] nchar(1)
,   [Model] nvarchar(50)
,   [CPPartNo] nvarchar(50)
,   [FH] decimal(10,10)
,   [FL] decimal(10,10)
,   [FPI] int
,   [TR] nchar(1)
,   [FinThk] decimal(10,10)
,   [FinMat] nchar(1)
,   [TubeOD] int
,   [Rifled] nchar(1)
,   [WallThk] decimal(10,10)
,   [CKT] int
,   [RD] int
,   [Split] nvarchar(50)
,   [CKT1] int
,   [CKT2] int
,   [CKT3] int
,   [CKT4] int
,   [Feed1] int
,   [Feed2] int
,   [Feed3] int
,   [Feed4] int
,   [Altitude] decimal(10,10)
,   [Connection] decimal(10,10)
,   [Header] decimal(10,10)
) 

SqlCeCommand.ExecuteNonQuery() returns -1, but this must be OK because it creates the table.

If a table exists, the SELECT statement works fine:

SqlCeException: Expression evaluation caused an overflow. [ Name of function (if known) = ] Expression evaluation caused an overflow. [ Name of function (if known) = ] HResult: -2147217900 NativeError: 25901 Source: SQL Server Compact ADO.NET Data Provider

Does anyone know how to read the HResult or NativeError?

My INSERT statement isn't too long or something, is it?

If it helps, I've uploaded my Visual Studio 2010 C# project SqlCeTool (without the binaries) >> HERE << (I will remove my project link after this issue is resolved).

Answer 1

You are creating a decimal values with equal precision and scale, is that intended? As it stands, you are creating fields like Altitude which can contain values of.0000000000 to.9999999999 (assuming I counted right). I believe you will want to adjust your precision and scale to be something like Altitude(20,10)

Books On Line article discussing Precision, Scale, and Length Money quote: "Precision is the number of digits in a number. Scale is the number of digits to the right of the decimal point in a number. For example, the number 123.45 has a precision of 5 and a scale of 2."
