Microsoft JET Database Engine 错误 '80040e14'

UPDATE 语句的语法错误。

代码如下：
set Command1 = Server.CreateObject("ADODB.Command"
Command1.ActiveConnection = MM_obdc_STRING
Command1.CommandText = "UPDATE TITLE SET bscount=bscount+1 WHERE TID=" + Replace(Command1__t_id, "'", "''" + " "
Command1.CommandType = 1
Command1.CommandTimeout = 0
Command1.Prepared = true
Command1.Execute()


不知道有何错误
