”可供更新的查询“错误！！

Question

ADO连接，代码：
   adodataset1.edit   
   adodataset1.fieldyname("dev"):='fdsdafa';
   adodataset1.post
出现错误“可供更新的查询”
   why?????

Answer 1

adodataset1.fieldyname("dev").asstring:='fdsdafa'
//用上面的那个，你只是确定了字段，但是没有确定字段的赋值方式

Answer 2

adodataset1.fieldyname('dev').AsString := 'fdsdafa';

Answer 3

呵呵，好像也少了个'b',adodataset1.fieldByname('dev').asstring:='fdsdafa'

Answer 4

ADO连接，代码：
   adodataset1.edit;  
   adodataset1.fieldyname('dev').Value:='fdsdafa';
   adodataset1.post;

Answer 5

来晚了，前面的说的很清楚了   adodataset1.fieldyname('dev').Value:='fdsdafa';

Answer 6

ADO连接，代码：
   adodataset1.edit   
   adodataset1.fieldyname("dev").value:='fdsdafa';

还是出现错误“可供更新的查询”
   why?????
