SAPbobsCOM.BoObjectTypes.BoRecordset

Question

Hi Experts,
I am new to SAP Business One SDK, I created a this code :
Dim oRecordSet As SAPbobsCOM.Recordset
Dim oItem1 As SAPbouiCOM.EditText = oForm.Items.Item("Item_1").Specific
oRecordSet = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)
oRecordSet.DoQuery("SELECT TOP 1 T0.[DocID] FROM [dbo].[@Testtable]  T0 ORDER BY T0.[DocID] DESC")
If oRecordSet.RecordCount > 0 Then
      oItem1.Value = oRecordSet.Fields.Item(0).Value
Else
      oItem1.Value = 1
End If
I have a clean database and it has no record at all. It gives me a correct value in my first testing but when I try to truncate my table it give me other record number. please help me about what does SAPbobsCOM.BoObjectTypes.BoRecordset do.

Answer 1

this is the script in my sql
CREATE TABLE [dbo].[@Testtable](
   [ID] [int] NOT NULL,
    [DocEntry] [int] NOT NULL,
    [DocNum] [int] NULL,
CONSTRAINT [Testtable] PRIMARY KEY CLUSTERED
    [ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
Im still trying to figuring it out.
