[VB.NET]问个问题

问个问题 mycommand=new oledbcommand( "select * from password where userid= '' " &txtuserid & " '' ",myconnection) 请大家看下这句话有错误么 myreader=mycommand.executereader 着是错误的地方 定义的都没有问题的 提示信息是from 语法错啊 conn.open() Dim sql = "select * from logo where name= '' " & TextBox1.Text & " '' " Dim comm As New Data.OleDb.OleDbCommand(sql,conn) Dim dr As OleDbDataReader = comm.ExecuteReader() dr.Read() If TextBox2.Text = dr.GetString(1) Then s = New System.Threading.Thread(AddressOf Module1.runF3) s.Start() Me.Close() Else MessageBox.Show( "密码输入错误,请重新输入! ") TextBox2.Text = " " End If __________________________________________________________________________ 1.由于某些是关键字，最好使用[],如select * from [password] 2，保证字段类型正确，如整型字段不加 ''，如 "select * from [password] Where userid = " + userID 3，替换 ''，如Dim sql = "select * from logo where name= '' " + TextBox1.Text.Replace( " '' "," '' '' ") + " '' " __________________________________________________________________________ 我在学习楼上的高手能不能讲的细点呀 虽然不是我提的问题 但我也想听 拜托了 __________________________________________________________________________ 你的那个表名方便的话你修改下！是关键字啊！ __________________________________________________________________________ To:net_lover(【孟子E章】) 怎么通过sql语名存储 ''符号? __________________________________________________________________________
