problem writing dataframe to oracle - aliyesami - Sep-25-2021
i have a simple csv file as follows :
Output:1,'sami'
2.'john',
3,'mary'
4,'peter'test(id, name) the code is as follows minus DB connection details since connection is fine :
#df=pd.read_csv('test.csv',encoding= 'unicode_escape', header = None)
df=pd.read_csv('test.csv',encoding= 'unicode_escape' )
print(df)
df.shape
df.info()
df.to_sql('test', engine, index=False, if_exists='append')[/python]I am trying to load the csv using pandas data frames but if i dont put the header in csv as "id,name" it does not insert rows and throws "invalid identifier " error.
I want to load this csv file in the table without having to put a header .
please advise .The code and error are below.
Note: I have tried using header=None ,still doesnt work .
Note2: plz note that if I put the header Id,Name in the csv file the code works fine and loads the rows in the table.
see attached outputs for both cases , first one is without using the header clause and second case is using header clause.

thanks but the link you posted has no relation to my issue. as I stated I don't have any issue in connection or loading as long as I keep the header . I want to know how to load the data when the csv file has no header

Did i post this in a wrong group ?

I am not sure I understand. If I understand then I do not know what your database field names are but perhaps you just need to use something as in the following.
df=pd.read_csv('test.csv', names=["Id", "Name"])
