这是在执行这样的操作后出现的提示:
AnsiString sql="select count(*) from biao1"
adoquery1->close();
adoquery1->sql->clear();
adoquery1->sql->add(aql);
adoquery1->execsql;
int k;
k=adoquery1->fields->fields[0]->AsInteger;
就是在执行这样的赋值语句时出现的问题，
什么原因呢》如何解决？
AnsiString sql="select count(*) as ALLCOUNT from biao1"
AnsiString sql ="select count(*) as ALLCOUNT from biao1"
adoquery1->close();
adoquery1->sql->clear();
adoquery1->sql->add(aql);
adoquery1->execsql;
k = adoquery1->fieldbyname("ALLCOUNT")->AsInteger;
AnsiString sql="select count(*) from biao1"
adoquery1->close();
adoquery1->sql->clear();
adoquery1->sql->add(aql);
adoquery1->execsql;//把这句改为 adoquery1->Active=true ;
int k;
