我从Excel导入348k行数据到VB.net SQL。 我得到这个错误：超时过期

我得到这个错误：

system.data.sqlclient.sqlexception超时。 在操作完成之前已经超时的时间或者服务器没有响应。

码：

Dim ExcelConnection As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\z.fontanilla\Documents\etl.xlsx;Extended Properties=""Excel 12.0 Xml;HDR=Yes""") ExcelConnection.Open() Dim expr As String = "SELECT * FROM [Sheet1$]" Dim objCmdSelect As OleDbCommand = New OleDbCommand(expr, ExcelConnection) Dim objDR As OleDbDataReader Dim SQLconn As New SqlConnection() Dim ConnString As String = "Data Source=cyayay\sqlexpress;Initial Catalog=reportingDB;Integrated Security=True" SQLconn.ConnectionString = ConnString SQLconn.Open() Using bulkCopy As SqlBulkCopy = New SqlBulkCopy(SQLconn) bulkCopy.DestinationTableName = "tFalse" Try objDR = objCmdSelect.ExecuteReader bulkCopy.WriteToServer(objDR) objDR.Close() SQLconn.Close() Catch ex As Exception MsgBox(ex.ToString) End Try End Using ExcelConnection.Close()

您可以尝试将objCmdSelect对象上的CommandTimeout属性设置为700（或其他）值。
