有关OdbcDataReader

[Glory_genius]

各位帮忙看下面的程序怎么处理啊？
String sch = "select password from user where name=" + comboBox1.Text;
OdbcCommand schcomm = new OdbcCommand(sch, this.odbcConnection1);
this.odbcConnection1.Open();
OdbcDataReader schrd = schcomm.ExecuteReader();
错误提示：未处理 System.Data.Odbc.OdbcException
Message="ERROR [07002ψ] [Microsoft][ODBC Microsoft Access Driver] 参数不足，期待是 1。"
Source="ACEODBC.DLL"
