Problems of multi-connection query optimization based on hybrid intelligent algorithm is similar to the ones of classical TSP. Via the TSP model, it uses genetic algorithm to search for a preliminary better solution space of the problem, initializing the solutions above with the ant pheromone, then obtaining the optimal solutions of the whole space by ant colony algorithm. Comparing and analyzing the time complexity and solution quality, to verify the better optimization results with the hybrid intelligent algorithm.%由于数据库多连接查询优化问题类似于经典TSP 问题，因此文章采用 TSP 模型进行多连接查询优化，利用遗传算法进行搜索得到初步较优解空间，并用蚂蚁信息素初始化，然后进行蚁群算法搜索得到整个空间的最优解。通过仿真实验从时间复杂性和解质量两个方面进行对比分析，验证本混合智能算法在数据库多连接查询优化中具有更好的优化效果。
