如何从 vb.net 中的 ConnectionObject.Execute() 方法获取受影响的记录数

Question

I am deleting entries in table using Connection object Execute() function. I am unable to get numbers of rows affected. Could someone help?

Dim db As ADODB.Connection
db = OpenDatabase(ConnectionString)
deleteExams = "delete from  [Table2] where  [PlanDate] < '" & sDate & "'"
db.Execute(deleteExams)  
db.Close()

the ADIDB execte method has a affected rows option see https://docs.microsoft.com/de-de/sql/ado/reference/ado-api/execute-method-ado-connection?view=sql-server-ver16

    Dim ObjAffectedrows As New Object
    db.Execute(deleteExams, ObjAffectedrows)
    Dim LongAfeected_Rows As Long = CLng(ObjAffectedrows)
    Dim LongAfeectedRows As Long
    Long.TryParse(ObjAffectedrows.ToString, LongAfeectedRows)
