我有一张大学桌子和一张部门桌子。大学表有两列:id和name,它有一些行:
+----+-------------------------+
| id | name |
+----+-------------------------+
| 1 | College of Engineering |
| 2 | College of Science |
| 3 | College of Business |
| 4 | College of Liberal Arts |
+----+-------------------------+
该部门有三列:id,name和college_id
+----+------+------------+
| id | name | college_id |
+----+------+------------+
现在我有一个csv文件,其中包含部门列表和学院名称:
Department of Computer Science, College of Engineering
Department of Mathematics, College of Science
Department of Histiry, College of Liberal Arts
现在我想使用LOAD DATA INFILE
将csv文件加载到department表中,但departbemt表需要college_id,而csv文件只有学院名称。是否有可能在LOAD DATA INFILE
条款中获得大学的ID?
谢谢!
答案 0 :(得分:-1)
LOAD DATA LOCAL INFILE 'path to .csv' INTO TABLE college
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(name)
我希望id是auto_increment。使用这个想法创建College表,之后创建一个包含csv文件中所有列的临时表。然后使用临时表和大学表,你可以填写部门表。
