请大家看看我的代码错在那里！~~
Dim   strCon1   As   String   =   "   Provider   =   Microsoft.Jet.OLEDB.4.0   ;   Data   Source   =   hjlotus.mdb   "
                Dim   myconn1   As   New   OleDb.OleDbConnection(strCon1)
                myconn1.Open()
                Dim   strdel   As   String   =   "delete   kcb   where   库存货号= ' "   &   _TextBox1.Text   &   " ' "
                Dim   myCommand1   As   OleDb.OleDbCommand   =   New   OleDb.OleDbCommand(strdel,   myconn1)
                myCommand1.ExecuteNonQuery()
                myconn1.Close()
我要作的是删除符合条件记录
提示这一句出错：myCommand1.ExecuteNonQuery()

[解决办法]
语句加上from
delete from kcb where 库存货号= ' " & _TextBox1.Text & " ' "
