我正在尝试将数据从python字典插入mySql DB。但我不明白我的SQL查询出了什么问题。
我收到此错误:
pymysql.err.ProgrammingError:(1064,u“您的SQL错误
句法;检查与您的MySQL服务器版本相对应的手册
在``DiedIn''('name','city')VALUES附近使用的正确语法
('\'Ethel_Merman \'','\'New_York_City \\ n \'')'在第1行“)
这是我的代码:
import pymysql.cursors
wasBornIn = {}
with open("wasBornIn.txt") as f:
for line in f:
(key, val) = line.split(':')
wasBornIn[key] = val
diedIn = {}
with open("diedIn.txt") as f:
for line in f:
(key, val) = line.split(':')
diedIn[key] = val
isLocatedIn = {}
with open("isLocatedIn.txt") as f:
for line in f:
(key, val) = line.split(':')
isLocatedIn[key] = val
connection = pymysql.connect(host='********', user='******', password='******', db='*******',
charset='utf8mb4', cursorclass=pymysql.cursors.DictCursor)
try:
with connection.cursor() as cursor:
# Create a new record
sql = "DROP TABLE DiedIn"
cursor.execute(sql)
with connection.cursor() as cursor:
# Create a new record
sql = "DROP TABLE isLocatedIn"
cursor.execute(sql)
with connection.cursor() as cursor:
# Create a new record
sql = "DROP TABLE BornIn"
cursor.execute(sql)
with connection.cursor() as cursor:
sql = "CREATE TABLE `DiedIn`(`name` varchar(100) COLLATE utf8_bin NOT NULL, `city` varchar(50) COLLATE utf8_bin NOT NULL, " \
"PRIMARY KEY(`name`)) ENGINE = InnoDB DEFAULT CHARSET = utf8" \
" COLLATE = utf8_bin;"
cursor.execute(sql)
with connection.cursor() as cursor:
sql = "CREATE TABLE `isLocatedIn`(`name` varchar(150) COLLATE utf8_bin NOT NULL, `location` varchar(50) COLLATE utf8_bin NOT NULL, " \
"PRIMARY KEY(`name`)) ENGINE = InnoDB DEFAULT CHARSET = utf8" \
" COLLATE = utf8_bin;"
cursor.execute(sql)
with connection.cursor() as cursor:
sql = "CREATE TABLE `BornIn`(`name` varchar(100) COLLATE utf8_bin NOT NULL, `city` varchar(50) COLLATE utf8_bin NOT NULL, " \
"PRIMARY KEY(`name`)) ENGINE = InnoDB DEFAULT CHARSET = utf8" \
" COLLATE = utf8_bin;"
cursor.execute(sql)
with connection.cursor() as cursor:
for key, value in diedIn.iteritems():
strKey = repr(key)
strValue = repr(value)
sql = "INSERT INTO 'DiedIn' ('name', 'city') VALUES (%s, %s);"
cursor.execute(sql, (strKey, strValue))
# connection is not autocommit by default. So you must commit to save
# your changes.
connection.commit()
finally:
connection.close()
谢谢您的帮助。
最佳答案
尝试:sql = "INSERT INTO 'DiedIn' (name, city) VALUES ('%s', '%s');"
