3단원: 보고서 정의에 대한 필드 목록 검색

모든 보고서 정의에는 보고서의 데이터를 나타내는 필드 목록이 있어야 하므로 쿼리로부터 필드 목록을 생성해야 합니다.

필드 목록을 생성하려면

  • 프로젝트에서 GenerateFieldsList() 메서드의 코드를 다음 코드로 바꿉니다.
Public Sub GenerateFieldsList()
   Dim command As SqlCommand
   Dim reader As SqlDataReader
   
   ' Executing a query to retrieve a fields list for the report
   command = m_connection.CreateCommand()
   m_commandText = "SELECT Person.CountryRegion.Name AS CountryName, Person.StateProvince.Name AS StateProvince " + "FROM Person.StateProvince " + "INNER JOIN Person.CountryRegion ON Person.StateProvince.CountryRegionCode = Person.CountryRegion.CountryRegionCode " + "ORDER BY Person.CountryRegion.Name"
   command.CommandText = m_commandText
   
   ' Execute and create a reader for the current command
   reader = command.ExecuteReader(CommandBehavior.SchemaOnly)
   
   ' For each field in the resultset, add the name to an array list
   m_fields = New ArrayList()
   Dim i As Integer
   For i = 0 To reader.FieldCount - 1
      m_fields.Add(reader.GetName(i))
   Next i
End Sub 'GenerateFieldsList
