在c ++/java中创建sql查询？

#include<mysqlx/xdevapi.h>

int main() {
    try {
        // 建立数据库连接
        mysqlx::Session session("localhost", 33060, "user", "password");
        mysqlx::Schema schema = session.getSchema("your_schema");
        mysqlx::Table table = schema.getTable("your_table");

        // 创建SQL查询
        std::string sql = "SELECT * FROM your_table";
        mysqlx::RowResult result = session.sql(sql).execute();

        // 输出查询结果
        for (const auto &row : result) {
            std::cout<< row[0].get<std::string>()<< std::endl;
        }

    } catch (const std::exception &e) {
        std::cerr << "Error: " << e.what()<< std::endl;
    }

    return 0;
}
