如何将excelsheet的数据同时导入到关系表中
how to import data from excel sheet into relational tables at the same time
我正在尝试导入 excel sheet 像图片一样的锁
excel sheet
分成 3 个 table 具有一对多关系
像这些
the tables i want to import to
我可以按原样导入 table 但这将是不好的做法
请帮我解决这个问题
我在堆栈溢出中寻找答案，但我没有找到答案
这可能是我的问题

我在这个网站的某个地方找到了答案
就像这样
self.cur.execute("SELECT GlId FROM gradelevel WHERE GradNumber = ? ", (greadn,))
rows = self.cur.fetchone()
if rows:
GreadLvl_ID = rows[0]
else:
self.cur.execute("INSERT INTO gradelevel(GradNumber)VALUES(?)",(greadn,))
self.cur.execute("SELECT GlId FROM gradelevel WHERE GradNumber = ? ", (greadn,))
rows = self.cur.fetchone()
GreadLvl_ID = rows[0]
greadID = self.cur.lastrowid
self.cur.execute("SELECT CID FROM classnumber WHERE ClassNumb = ? AND GradID = ?", (claasn, GreadLvl_ID))
rows1 = self.cur.fetchone()
if rows1:
class_ID = rows1[0]
else:
self.cur.execute("INSERT INTO classnumber(ClassNumb, GradID)VALUES(?,?)",(claasn, GreadLvl_ID))
