Question

你好我想用excel文件或.txt将数据导入到数据库中，并使用＆＃34;加载数据Infile＆＃34;但我文件的路径包含＆＃34; \＆＃34;女神不被Mysql接受

要清楚这是我的PYTHON代码：

def parcourir(self):
        fi=QFileDialog.getOpenFileName(self)
        self.Pathfile.setText(fi)

def chargeFile(self):        
        try:
            fiche=open(self.Pathfile.text(),'r')
        except IOError :
            QtGui.QMessageBox.warning(self,"erreur","fichier nontrouvé")
        connection = MySQLdb.connect (host = "localhost", user = "root", passwd = "", db = "lexique")
        cursor = connection.cursor()
        query="LOAD DATA INFILE 'self.Pathfile.text()' INTO TABLE tbl_lexique FIELDS TERMINATED BY ',' ENCLOSED BY '\"'LINES TERMINATED BY '\n'"
        cursor.execute( query )
        connection.commit()
        ...................

Answer 1

您应该考虑使用参数化查询：

query="""
    LOAD DATA INFILE '%s' INTO TABLE tbl_lexique 
    FIELDS TERMINATED BY '%s' 
    ENCLOSED BY '%s' 
    LINES TERMINATED BY '%s'
    """

# you can also try converting your windows
# path to a posix path
path = self.Pathfile.text().replace('\\', '/')
cursor.execute(query, (path, ',', '"', '\n'))

Answer 2

嗯，现在终于工作了:)我只是把这个问题：

query = "LOAD DATA INFILE '%s' " % self.Pathfile.text()
query += " INTO TABLE tbl_lexique FIELDS TERMINATED BY ',' ENCLOSED BY '\\\"' LINES TERMINATED BY '\\n'" 
cursor.execute( query )

数据加载infile_python和Qfiledialog
