我正在尝试将文本文件发送到MySQL数据库。我正在尝试使用python 3.2中的mysql连接器执行此操作。问题是关于LOAD DATA INFILE语法。您可以在上面找到我的代码。我的第一个问题是仍然有解决此问题的方法。请注意,我尝试使用local-infile = 1选项,Python不允许使用此选项。其次,还有其他方法可以将此数据作为块发送到mysql数据库吗?
from __future__ import print_function
import os
import mysql.connector
from mysql.connector import errorcode
config = {
'user':'root',
'password':'3778',
## 'host':'localhost',
# 'database':'microstructure',
# 'local-infile':'1',
}
DB_NAME = 'EURUSD'
TABLES ={}
TABLES['microstructure']=(
"CREATE TABLE `microstructure` ("
# " `p_id` int NOT NULL AUTO_INCREMENT,"
" `ticker` varchar(255),"
" `time` date,"
" `last_price` decimal(6,3)"
") ENGINE=InnoDB")
TABLES['cumulative']=(
"CREATE TABLE `cumulative` ("
" `p_id` int NOT NULL AUTO_INCREMENT,"
" `ticker` varchar(255),"
" `time` date,"
" `last_price` decimal(6,3),"
" PRIMARY KEY(`p_id`)"
") ENGINE=InnoDB")
cnx = mysql.connector.connect(**config)
cursor = cnx.cursor()
path_txt = 'C:/Users/ibrahim/Desktop/testfile.txt'
def create_database(cursor):
try:
cursor.execute(
"CREATE DATABASE IF NOT EXISTS {} DEFAULT CHARACTER SET 'utf8'".format(DB_NAME))
except mysql.connector.Error as err:
print("Failed creating database: {}".format(err))
exit(1)
try:
cnx.database = DB_NAME
except mysql.connector.Error as err:
if err.errno == errorcode.ER_BAD_DB_ERROR:
create_database(cursor)
cnx.database=DB_NAME
else:
print(err)
exit(1)
for name, ddl in TABLES.items():
try:
print("Creating table {}: ".format(name), end ='')
cursor.execute(ddl)
except mysql.connector.Error as err:
if err.errno == errorcode.ER_TABLE_EXISTS_ERROR:
print("Already exists")
else:
print(err)
else:
print("OK")
cursor.execute("SET @@global.local_infile = 1")
cursor.execute("LOAD DATA LOCAL INFILE 'testfile.txt' into table microstructure")
os.system("start")
cursor.close()
最佳答案
在MySQLdb中时,我使用它来启用LOAD DATA LOCAL INFILE
功能:
MySQLdb.connect(..., local_infile=True)
关于python - Python中的MySQL连接器不允许LOAD DATA INFILE语法,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/15233244/
