  • 全国地区编码表
  • 需求1：查出‘安平县’及其上级区域的编码和名称
    • 方法1：使用`WITH RECURSIVE`递归（版本8.0以上支持）
    • 方法2：使用纯SQL语句
    • 方法3：新增字段`area_parent_path`（路径枚举）
  • 需求2：查询‘襄阳市’全部下级地区
    • 方法1：使用`WITH RECURSIVE`递归
    • 方法2：使用纯SQL语句
    • 方法3：使用内置函数`FIND_IN_SET`
  • 总结

需求1：查出‘安平县’及其上级区域的编码和名称

方法1：使用WITH RECURSIVE递归（版本8.0以上支持）

WITH RECURSIVE county AS (SELECTregion.area_code,region.area_parent_code,region.area_name FROMregion WHEREregion.area_code = '131125' UNION ALLSELECTregion.area_code,region.area_parent_code,region.area_name FROM region,county WHERE county.area_parent_code = region.area_code )
SELECT * FROM county

region,county可以换成region JOIN county
region JOIN county WHERE county.area_parent_code = region.area_code 可以把WHERE换成ON
可以把*改成area_code,area_name，只输出需要的字段

方法2：使用纯SQL语句

使用自定义变量@

SELECTregion.area_code,region.area_parent_code,region.area_name
FROM(SELECT@area_codes AS area_codes,( SELECT @area_codes := area_parent_code FROM region WHERE area_code = @area_codes ) t1 FROMregion,( SELECT @area_codes := '131125' ) t2 WHERE@area_codes IS NOT NULL ) t3,region
WHEREregion.area_code = t3.area_codes

方法3：新增字段area_parent_path（路径枚举）

生成area_parent_path值的PHP代码：

RegionModel::query()->chunkById(100, function ($items) {foreach ($items as $item) {$areaParentPath = $item->area_parent_path;if (!empty($item->area_parent_code)) {$areaParentPath .= ',' . $item->area_parent_code;$item4 = RegionModel::query()->where('area_code', $item->area_parent_code)->first();if (!empty($item4) && !empty($item4->area_parent_code)) {$areaParentPath .= ',' . $item4->area_parent_code;$item3 = RegionModel::query()->where('area_code', $item4->area_parent_code)->first();if (!empty($item3) && !empty($item3->area_parent_code)) {$areaParentPath .= ',' . $item3->area_parent_code;$item2 = RegionModel::query()->where('area_code', $item3->area_parent_code)->first();if (!empty($item2) && !empty($item2->area_parent_code)) {$areaParentPath .= ',' . $item2->area_parent_code;}}}}$areaParentPath = trim($areaParentPath, ',');var_dump($areaParentPath);if (!empty($areaParentPath)) {$item->update(['area_parent_path' => $areaParentPath]);}}
});

例如：

这样一来查询SQL就简单了，利用内置函数FIND_IN_SET(str,strlist)，而且效率比纯SQL更好

SELECT area_code,area_parent_code,area_name
FROM region
WHERE area_code = '131125' ORFIND_IN_SET(area_code,( SELECT area_parent_path FROM region WHERE area_code = '131125' ));

可以改成UNION ALL，比OR效率更好

SELECTarea_code,area_parent_code,area_name
FROMregion
WHEREarea_code = '131125' UNION ALL
SELECTarea_code,area_parent_code,area_name
FROMregion
WHEREFIND_IN_SET( area_code, ( SELECT area_parent_path FROM region WHERE area_code = '131125' ) );

需求2：查询‘襄阳市’全部下级地区

方法1：使用WITH RECURSIVE递归

WITH recursive county AS (SELECTregion.area_code,region.area_parent_code,region.area_name,region.area_type FROMregion WHEREregion.area_code = '420600' UNION ALLSELECTregion.area_code,region.area_parent_code,region.area_name,region.area_type FROM region JOIN county ON county.area_code = region.area_parent_code ) SELECT*
FROMcounty

方法2：使用纯SQL语句

SELECTT3.area_code,T3.area_parent_code,T3.area_name,T3.area_type
FROM(SELECT@codes AS _ids,( SELECT @codes := GROUP_CONCAT( area_code ) FROM region WHERE FIND_IN_SET( area_parent_code, @codes ) ) AS T1 FROMregion,( SELECT @codes := '420600' ) T4 WHERE@codes IS NOT NULL ) T2,region T3
WHEREFIND_IN_SET( T3.area_code, T2._ids );

注意：数据量非常大时，第二种方法会丢失一些数据，暂时还没找到原因和解决办法。
可能是@code := GROUP_CONCAT( area_code )的长度超出了临时表的限制吧


方法3：使用内置函数FIND_IN_SET

SELECTregion.area_code,region.area_parent_code,region.area_name,region.area_type
FROMregion
WHEREarea_code = '420600' OR FIND_IN_SET('420600', area_parent_path)

可以改成UNION ALL，比OR效率更好

SELECTregion.area_code,region.area_parent_code,region.area_name,region.area_type
FROMregion
WHEREarea_code = '420600' UNION ALL
SELECTregion.area_code,region.area_parent_code,region.area_name,region.area_type
FROMregion
WHEREFIND_IN_SET('420600',area_parent_path)

总结

可以发现：方法1查询效率最好；方法3查询效率次之；方法2查询效率最差还有可能丢失数据。
所以在MySQL版本支持WITH RECURSIVE语法的条件下尽量使用该语法吧。若不支持就选择FIND_IN_SET
