SqlCommandBuilder DeriveParameters Ouput Arg gets wrong direction

[JM]

First, I am using the Enterprise Library DatabaseFactory to get a Database
object. I have traced the issue down to the SqlCommandBuilder
DeriveParameters method.

Given a stored procedure args:

CREATE PROCEDURE UpdDept
( @KeyDepartmentIdentifier UNIQUEIDENTIFIER,
@KEYTimestamp BINARY(8),
@NewName NVARCHAR(50),
:
:
@OutTimeStamp BINARY(8)
)

Wheh I call the Database.DiscoverParameters (aka -
SqlCommandBuilder.DeriveParameters) the @OutTimeStamp DbPArameter
(SqlParameter) has its direction set to InputOutput.

SQL procedure parameters are either input or output. InputOut is not
defined (SQL 2005).

Why is the direction set to InputOutput?

This requires that I initialize the output parameter.

Sorry the parameters should have read:

CREATE PROCEDURE UpdDept
( @KeyDepartmentIdentifier UNIQUEIDENTIFIER,
@KEYTimestamp BINARY(8),
@NewName NVARCHAR(50),
:
:
@OutTimeStamp BINARY(8) OUTOUT
