我从我的数据库中获取数据,我希望将这些数据作为excel文件中的表.
所以,我写了以下内容：
@H_502_16@解决方法
所以,我写了以下内容：
Dim sheetToPopulate As Excel.Worksheet = getSheet()
Dim reader As OleDbDataReader
Dim query As String = "SELECT * FROM dataTable"
Dim cmd As New OleDbCommand(query,oleConn)
Dim reader As OleDbDataReader
oleConn.Open()
reader = cmd.ExecuteReader()
Do While reader.Read()
// How use the reader to populate the sheet at once.
// I have the sheet object as sheetToPopulate.
// cell.Vaule = reader.GetString(0) ' It would be very in-efficient and complex.
// How can I dump the table to my excel sheet ?
Loop
reader.Close()
oleConn.Close()
应该有一个明显的方法来做到这一点？
将数据库表转储到Excel工作表？
[ 我是不是该 ？ ]
Should I use dataset of something.. ? If yes,how to proceed for that ?
请帮助..我是新来的!!
以下是我解决这个问题的方法：
Private Function getData(ByVal query As String,ByVal conStr As String) As Object
Dim adapter As New Data.OleDb.OleDbDataAdapter(query,conStr)
Dim dataSet As New Data.DataSet
adapter.Fill(dataSet)
Dim dataTable As Data.DataTable = dataSet.Tables(0)
Dim data(dataTable.Rows.Count,dataTable.Columns.Count - 1) As Object
For col = 0 To dataTable.Columns.Count - 1
For row = 0 To dataTable.Rows.Count - 1
data(row,col) = dataTable.Rows(row).ItemArray(col)
Next
Next
Return data
End Function
Then Finally,do the following to the range where you want to have this data
range.Value = getDate(query,conStr)
这解决了整个问题！
