Subject: [SystemiDotNet] System i Logical Files and .NET
Here is some of my .NET code ( i am not a VB guru either...much to learn).
The physical file has no keys, but I am trying to use a logical built over
it.
The logical has a 3 part key (customer#, Invoice#, Invoice date).
I am using IBM .NET provider 6.1.
I am building a dataset.
Adapter = New iDB2DataAdapter("SELECT * FROM Duane.ARTRANL1", cni5)
Dim iDB2CB As iDB2CommandBuilder = New iDB2CommandBuilder(Adapter)
Adapter.DeleteCommand = iDB2CB.GetDeleteCommand
Adapter.InsertCommand = iDB2CB.GetInsertCommand
Adapter.UpdateCommand = iDB2CB.GetUpdateCommand
The error happens while building the Delete Command.
Here is the error:
"The table specified in the SELECT statement does not contain a unique key
or identifier column, or
the SELECT statement does not include all of the key columns."
It looks like it doesn't like the keys from the logical. Is this because
the physical file does not have the "Unique" keyword in the DDS? These DDS
files came from the s/36 and we still have s/36 programs that use these
files daily.
So, I was going to build an identifier column in the physical file. Can't
because it is not an SQL created file.
Any ideas?
