我有一个excel文件,我试图将其放入mysql。我想用python插件xlrd提取32个字段并放入mysql。数据的布局如下:
我的方法是迭代行和列,随时添加字段名。代码添加了字段名称,但添加数据时出错。 (我创建了表'OilProvedReservesHistory',索引为唯一字段):
def get_data_from_sheet(sheet_index, table, start_row, end_row, end_col):
for row in range(start_row - 1, end_row - 1):
for col in range(end_col):
cell = sheet.cell(row,col)
if col == 0:
fieldname = cleanup_field(cell.value)
if fieldname != ("Blank Cell"):
sql = "ALTER TABLE OilProvedReservesHistory ADD %s VARCHAR(20)" % fieldname
c.execute(sql)
else:
data = cleanup_data(cell)
if data != ("Blank Cell"):
postToMySQL(data,fieldname,table)
def postToMySQL(data,fieldname,table):
#Generate sql query string
sql = "INSERT INTO " + table + " ("+ fieldname + ") VALUES %s"
c.execute(sql, data)
# Executes: ("""INSERT INTO OilProvedReservesHistory (US) VALUES 36.533""")
table = create_table_from_sheet_name()
sheet_index = 0
start_row = 5
end_row = 68
end_col = 32
get_data_from_sheet(sheet_index, table, start_row, end_row, end_col)
我得到的错误是:
_mysql_exceptions.ProgrammingError:(1064,“您的SQL语法有错误;请查看与您的MySQL服务器版本对应的手册,以便在第1行''36 .533'附近使用正确的语法”
你能帮我搞定吗?非常感谢!
答案 0 :(得分:1)
我猜你只是忘记了VALUES子句的括号。
INSERT INTO OilProvedReservesHistory (US) VALUES (36.533)
尝试将代码更改为:
sql = "INSERT INTO " + table + " ("+ fieldname + ") VALUES (%s)"
