                  问题描述

                  我有一个带有以下列表的 sqlite 数据库:

                  I have a sqlite database with a table with following columns :

                  id(int) , name(text) , dob(text)
                  

                  我想插入以下字典:

                  {"id":"100","name":"xyz","dob":"12/12/12"}
                  

                  字典键是列名.我怎样才能实现它?

                  Dictionary keys are the column names. How can i achieve it ?

                  推荐答案

                  这是一种保持参数安全的方法.(可能需要在表名部门打磨)

                  Here's a way which preserves parameter safety. (Might need polishing in the tablename department)

                  def post_row(conn, tablename, rec):
                      keys = ','.join(rec.keys())
                      question_marks = ','.join(list('?'*len(rec)))
                      values = tuple(rec.values())
                      conn.execute('INSERT INTO '+tablename+' ('+keys+') VALUES ('+question_marks+')', values)
                  
                  row = {"id":"100","name":"xyz","dob":"12/12/12"}
                  post_row(my_db, 'my_table', row)
