Save pandas (string/object) column as VARCHAR in Oracle DB instead of CLOB (default behaviour)

Question

i am trying to transfer a dataframe to oracle database, but the transfer is taking too long, because the datatype of the variable is showing as clob in orac

Answer 1

use str.zfill

df['product'].astype(str).str.zfill(9)

0    000012320
1    000234234
Name: product, dtype: object
