程序执行出错信息，[microsoft][odbc sql server driver]没有执行可选特性..(100)

代码如下: UserSession.Querytemp.close; UserSession.Querytemp.SQL.Clear; UserSession.Querytemp.SQL.Add('update usertables set passwords = asswords,nicheng=:nicheng,sex = :sex,email = :email,admin = :admin,'); UserSession.Querytemp.SQL.Add('howlong = :howlong,lastday = :lastday'); UserSession.Querytemp.SQL.Add(' where userid = ''' + UserSession.userid + ''''); UserSession.Querytemp.Parameters.ParamByName('passwords').Value := GY.Encrypt_text(IWEdit2.Text, UserSession.mm); UserSession.Querytemp.Parameters.ParamByName('sex').Value := IWComboBox1.Text; UserSession.Querytemp.Parameters.ParamByName('email').Value := IWEdit3.Text; UserSession.Querytemp.Parameters.ParamByName('nicheng').Value := IWEdit8.Text; UserSession.Querytemp.Parameters.ParamByName('admin').Value := GY.Encrypt_text(IWComboBox2.Text, UserSession.mm); UserSession.Querytemp.Parameters.ParamByName('howlong').Value := IWEdit4.Text; UserSession.Querytemp.Parameters.ParamByName('lastday').Value := StrTodate(IWEdit5.Text); UserSession.Querytemp.ExecSQL; end; 高手给看看是什么原因?

将此三句改为一句： UserSession.Querytemp.SQL.Add('update usertables set passwords = asswords,nicheng=:nicheng,sex = :sex,email = :email,admin = :admin,'); UserSession.Querytemp.SQL.Add('howlong = :howlong,lastday = :lastday'); UserSession.Querytemp.SQL.Add(' where userid = ''' + UserSession.userid + '''');改为 UserSession.Querytemp..SQL.Add('update usertables set passwords=asswords,nicheng=:nicheng,sex=:sex,email=:email,admin=:admin,howlong=:howlong,lastday=:lastday where userid='+'''+UserSession.userid+''');= asswords,nicheng=:nicheng,sex = :sex,email = :email,admin = :admin,');这样试一下~~
