你可以save your Excel sheet as in a CSV file，然后使用LOAD DATA INFILE命令将该文件导入到与Excel工作表相同列的MySQL临时表中，最后将临时表记录拆分为“城市”、“城镇”和“地区”。
一个前提：由于Excel文件中没有“id”字段，我想所有的id都是“auto_increment”字段；此外，“城镇”表的“大陆”字段将始终设置为空白值，因为该字段不存在于您的 Excel 工作表中；最后，我假设所有“名称”字段的最大长度为 255 个字符。
从您的示例数据开始，通过以 CSV 格式导出 Excel 工作表并将（例如）保存到“C:\Temp\excel.csv”文件中，您应该得到如下内容：
"city name","town name","district name"
"X","Y","A"
"X","Y","B"
"X","K","C"
"X","K","D"
要将此文件导入您的 MySQL 数据库，请创建一个具有以下内容的“excel2mysql.sql”文件，以及execute it:
DROP TABLE IF EXISTS excel_table;
CREATE temporary TABLE excel_table (
city_name VARCHAR(255),
town_name VARCHAR(255),
district_name VARCHAR(255)
) DEFAULT CHARSET utf8;
LOAD DATA LOCAL INFILE 'C:/Temp/excel.csv'
INTO TABLE excel_table
CHARACTER SET utf8
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES;
DROP TABLE IF EXISTS cities;
CREATE TABLE cities (
city_id int NOT NULL auto_increment,
city_name VARCHAR(255),
primary key (city_id)
) DEFAULT CHARSET utf8;
INSERT INTO cities
SELECT distinctrow NULL, city_name
FROM excel_table
ORDER BY city_name;
DROP TABLE IF EXISTS towns;
CREATE TABLE towns (
town_id int NOT NULL auto_increment,
city_id int NOT NULL,
town_name VARCHAR(255),
continent VARCHAR(255),
primary key (town_id)
) DEFAULT CHARSET utf8;
INSERT INTO towns
SELECT distinctrow NULL, city_id, town_name, ''
FROM excel_table, cities
WHERE cities.city_name=excel_table.city_name
ORDER BY town_name;
DROP TABLE IF EXISTS districts;
CREATE TABLE districts (
district_id int NOT NULL auto_increment,
town_id int NOT NULL,
district_name VARCHAR(255),
primary key (district_id)
) DEFAULT CHARSET utf8;
INSERT INTO districts
SELECT distinctrow NULL, town_id, district_name
FROM excel_table, towns
WHERE towns.town_name=excel_table.town_name
ORDER BY district_name;
