Question

我在整个程序中使用了插入，选择，更新，删除没有问题，但由于某种原因，这个特定的部分导致它除了并且不运行我发送它的SQL。我试图“更新SectionTable（AreaID）VALUES（'+ IntToStr（ActClient.AreaID）+'）WHERE SectionID ='+ IntToStr（iCount）” 具有ID“iCount”的部分存在于deffinately。 ActClient.AreaID为“2”，并在“SectionTable”表中覆盖空数据。

这里有什么问题？

OpenDatabase(slDb);
                        sltb:=sldb.GetTable('SELECT * FROM SectionTable WHERE SectionID='+IntToStr(iCount));
                        OutputDebugString(PAnsiChar(sltb.FieldAsString(sltb.FieldIndex['SectionID'])+sltb.FieldAsString(sltb.FieldIndex['Gender'])+sltb.FieldAsString(sltb.FieldIndex['CompetitionID'])));
                        sSQL := 'UPDATE SectionTable(AreaID) VALUES ('+IntToStr(ActClient.AreaID)+') WHERE SectionID='+IntToStr(iCount);
                        sldb.ExecSQL(sSQL);
                        CloseDatabase(slDb);

运行此错误时会显示此错误消息。
