UnicodeEncodeError: 在 python 中使用 to_sql 时

Question

I am trying to insert dataframe to oracle database using to_sql. Below is the code:

engine = create_engine('oracle+cx_oracle://'+username+':'+password+'@'+host+':'+port+'/'+sid) df.to_sql(name = table.lower(),schema=schema,con =engine,if_exists = 'replace', index=False)

I am getting below error: UnicodeEncodeError: 'ascii' codec can't encode character '\–' in position 81: ordinal not in range(128)

can someone please help on this.

Probably your database is UTF8 and you did not export your NLS_LANG variable in your session:

So I would try to first export your NLS_LANG to the character set you have in your database:

#export NLS_LANG=American_America.AL32UTF8

Then I would try to change your connection in cx_Oracle.connect method:

connection = cx_Oracle.connect("user/password@connectString",
    encoding="UTF-8", nencoding="UTF-8")

As you are using to_sql , you might try this before you try your connection

import os
os.environ["NLS_LANG"] = 'YOUR_NLS_LANG_VARIABLE'
