What is the best way to get the reverse behavior of the YesNo Boolean type in NHibernate mapping?
I want 'Y' to mean false and 'N' to mean true.
Is there a NoYes type? Do you write a custom type? something really easy?
This issue of needing to reverse the Boolean exists on at least one field on over 40 tables.
Trying to adapt to a leg...

If, for example, you're going to write a variant type class, you will naturally need identification of what type an instance of that class is carrying. I'm wondering if anyone knows of any official or semi-official (de-facto?) reference of all primitive datatypes one would possibly be interested in?
Only primitives, and no need for abs...

I want to convert a money datatype to a decimal, because I want to record the results to 8 decimal places.
For example, in a currency rate table I see the rate stored as 2871047428.20 as a money datatype; using Microsoft SQL Management Studio, I want to divide that by 10000000 in order to achieve the result 287.10474282; however the res...

Hello everyone,
My question is how to assign the DataType value for columns of special SQL Types like, uniqueidentifier/nvarchar/datetime/varbinary(max) -- I did not find a mapping between .Net data type and such 4 types of SQL column data type?
Here is a sample, which shows we need to assign the DataType (this sample maps .Net type to...
So I have a stored procedure in a SQLServer 2005 database, which retrieves data from a table, format the data as a string and put it into a varchar(max) output variable.
However, I notice that although len(s) reports the string to be > 8,000, the actual string I receive (via SQLServer output window) is always truncated to < 8,000 bytes....
Hello,
I'm working on an application that uses a third-party component, and this component returns a value that is of type UInt32.
I need to store this UInt32 in a Sql Server table. I was thinking about just use a simple int column and insert the value like this:
int value = (int)(cs - int.MaxValue);
But I'm not sure if this is the b...

It's a well known truth, that you don't can trust user inputs. These inputs can be even an security-problem, if they are used unfiltered. XSS and SQL-injections are possible problems coming from using unfiltered user-input (or input, that can be changed by the user).
To avoid such problems, you have to control all strings, that can be i...

As far as I know[*], C# defaults the plain-old-data-types (int, float, bool, etc) to sensible values. int a, float b, and bool c take on the values 0, 0.0f, and false, respectively.
Assuming this is so:
Should I explicitly give my variables values of 0, 0.0f, and false for clarity, or should I leave the values implicit, thus reducing ...
Are there any issues with using a byte[] as a primary key in a JPA Entity?
I want to use a UUID as my primary key, but stored as a string I feel it will be too large.
