Question

我有下面的SQL，它正在使用OleDBConnection和OleDBCommand执行，并且它会永远消失并最终超时，我不知道为什么。在执行此脚本之前，其他人都会被执行并且它们没问题。我不知道这个有什么特别之处。

begin
      insert into messages (message_id,message,store_in_log, message_group) 
         values (25000,'Production Floor','False','Locations');
      insert into messages (message_id,message,store_in_log, message_group) 
          values (25001,'Building 4 – A','False','Locations');
      insert into messages (message_id,message,store_in_log, message_group) 
          values (25002,'Building 3 – A','False','Locations');
      insert into messages (message_id,message,store_in_log, message_group) 
          values (25003,'Building 4 – B','False','Locations');
      insert into messages (message_id,message,store_in_log, message_group) 
          values (25004,'Building 4 – C','False','Locations');
      insert into messages (message_id,message,store_in_log, message_group) 
          values (25005,'Building 4 – D','False','Locations');
      insert into messages (message_id,message,store_in_log, message_group) 
          values (25006,'Quarantine','False','Locations');
      insert into messages (message_id,message,store_in_log, message_group) 
          values (25007,'Small Area','False','Locations');
end;

带OLEDB连接的VB代码：

        Dim sc As Script
        Dim C As New OleDb.OleDbConnection(CnStr)
        Dim Cmd As OleDb.OleDbCommand
        Dim sql As String
        For Each sc In s               
        sql = sc.OracleScript               

        Cmd = New OleDb.OleDbCommand(sql, C)
        Try
           Cmd.Connection.Open()
           Cmd.ExecuteNonQuery()
        Catch ex As Exception

        Finally
           Cmd.Connection.Close()
           Cmd.Dispose()
           Cmd = Nothing
        End Try

        Next

insert语句非常简单。 Have you check for locks？

Oracle简单的INSERT语句需要很长时间
