@@Identity (Transact-SQL) Is a system function that returns the last-inserted identity value.
To use this in a tSQL statement, you need to declare an output variable and set the value after inserting a new row into a table.
SET @RecordID=@@IDENTITY
Using VB.NET
Using MyCommand As IDbCommand = DB.CreateCommand
MyCommand.CommandText = "INSERT INTO [table](field) VALUES(@fieldValue) " _
& " SET @RecordID=@@IDENTITY"
Dim fieldValue As IDataParameter = MyCommand.CreateParameter
fieldValue.ParameterName = "@fieldValue"
fieldValue.Value = "Value"
MyCommand.Parameters.Add(fieldValue)
Dim RecordID As IDataParameter = MyCommand.CreateParameter
RecordID.ParameterName = "@RecordID"
RecordID.Direction = ParameterDirection.Output
MyCommand.Parameters.Add(RecordID)
MyCommand.ExecuteNonQuery()
End Using
Using xPress
MyCommand.Parameters.Add(xPress.Data.BuildParameter(MyCommand, "@RecordID", Nothing, ParameterDirection.Output))
