touch app.cpp, then copy the following C++ code into that file #include<iostream>#include<clickhouse/client.h>usingnamespaceclickhouse;intmain() {/// Initialize client connection.Clientclient(ClientOptions().Set
#include<clickhouse/client.h>usingnamespaceclickhouse;/// Initialize client connection.Clientclient(ClientOptions().SetHost("localhost"));/// Create a table.client.Execute("CREATE TABLE IF NOT EXISTS test.numbers (id UInt64, name String) ENGINE = Memory");/// Insert some values.{ Block bloc...
本文是我在阅读 Clickhouse 查询的执行流程时做的笔记,总结为代码导读指南,方便新人学习。 客户端侧:Client.cpp客户端调用 processQueryText 方法接收一条用户输入的 SQLbool processQueryText(const String &a…

clickhouse 使用的是 poco 这个网络库来处理网络请求，每个client连接的处理逻辑在 dbms/programs/server/TCPHandler.cpp的TCPHandler::runImpl()方法里面。除去握手，初始化上下文，异常处理和数据统计的代码，主要的业务可以抽象成:client发送的sql在 executeQuery 函数处理，processInsertQuery 和 processOrdinaryQuery 负责...
接着来到了Client.cpp文件ClickHouse Client启动的main()方法这里,一路来到mainImpl()方法。 关键步骤包括: 1)注册相关函数; 2)判断是否是交互模式,如果是交互式模式,输出client版本信息; // 如果满足以下条件之一, 则表示不是命令行交互模式, 设置is_interactive = false; ...
cpp #include <clickhouse/client.h> #include <iostream> #include <string> int main() { // 创建ClickHouse客户端实例 ClickHouse::Client client("localhost", 9000, "default", "your_password"); try { // 连接到ClickHouse服务器 client.Connect(); // 执行查询 std::string ...
