首先,本文面向有数据库开发经验的朋友。如果你自认“功力深厚”或者觉得本文对你没有什么帮助,那么请不要见笑,以下小弟写的代码。
在把EXCEL的数据导入数据库之前,先进行一些简单的准备工作:
1。把数据所在的EXCEL表另保存为DBF 4格式。
2。打开BCB,添加AdoTable(改名为DBFTable)和DataSource这两个控件
OK,准备工作,到此结束,剩下的就是打代码了
1。在Form_Load()事件中,加入以下代码:
AnsiString filepath=ExtractFilePath(FileName); //FileName为DBF文件名 AnsiString tablename=ExtractFileName(FileName).SubString(0,ExtractFileName(FileName).Length()-4);//去除文件的扩展名
//--------------------用于连接DBF文件-------------------------------- DBFTable->ConnectionString="Provider=Microsoft.Jet.OLEDB.4.0;Password=/"/";Data Source=/""+filepath+"/";Extended Properties=dbase 5.0;Persist Security Info=True"; DBFTable->TableName=tablename; DBFTable->Open();
2。新建一个类的成员函数void __fastcall ExcelToDB(TADOQuery *ADOQuery);
以下是函数的具体实现:
void __fastcall TDBFToDBForm::ExcelToDB(TADOQuery *ADOQuery) {//实现很简单,只是把DBFTable的数据逐项添加的本地的数据库 DBFTable->First(); for(int j=0;j<dbftable->RecordCount;j++) { ADOQuery->Append(); for(int i=0;i<dbftable->FieldCount;i++) ADOQuery->FieldByName(DBFTable->FieldList->Strings[i])->AsString=DBFTable->FieldByName(DBFTable->FieldList->Strings[i])->AsString; ADOQuery->Post(); DBFTable->Next(); } ShowMessage("导入成功!"); }</dbftable-></dbftable->
说明:DBFTable使用来装载EXCEL另保存的数据,而程序本身装载数据用的是ADOQuery(当然,你也可以改变),

Nginx performance monitoring and troubleshooting are mainly carried out through the following steps: 1. Use nginx-V to view version information, and enable the stub_status module to monitor the number of active connections, requests and cache hit rate; 2. Use top command to monitor system resource occupation, iostat and vmstat monitor disk I/O and memory usage respectively; 3. Use tcpdump to capture packets to analyze network traffic and troubleshoot network connection problems; 4. Properly configure the number of worker processes to avoid insufficient concurrent processing capabilities or excessive process context switching overhead; 5. Correctly configure Nginx cache to avoid improper cache size settings; 6. By analyzing Nginx logs, such as using awk and grep commands or ELK
