I have try to request data by CommandText
"Select * from table1 where field1=:field1"
If there are some param
ClientDataSet->Close();
ClientDataSet->CommandText="Select * from table1 where field1=:field1"
ClientDataSet->Params->ParamByName("field1")->AsString="123";
ClientDataSet->Open();
there should be some data, but I find that the result is empty
If I write param directly to CommandText
"Select * from table1 where field1='ABC' "
there will be no problem

Please Help.
