python – How can I fetch data in different columns of a dataframe from a database?

  • 0

[ad_1]

I was trying to fetch the data from a SQL server database into a pandas dataframe. But it was returning entire data into a single column instead of as it was in different columns in the database.When I tried to assign columnname to the dataframe it returned this error

6 columns passed, passed data had 1 columns
It was here when I realized that it is fetching the data into a single column.

So can anyone help me with how can I add fetch the data into different columns or split this data into different columns and assign column names?

Here is the code and the output that I got.

`def read(cursor):
try:
    print("Read")
    cursor = conn.cursor()
    cursor.execute("SELECT * FROM empDetail")
    df = pd.DataFrame(cursor)
    print(df)
except ValueError as e:
    print("Error",e)

`

Output
