Oracle SQL Query In Python with date User Input

Question

I'm trying to run SQL Query in python but I'm getting Error not a valid month while passing dates using user input.

The table has a date column in "MM/DD/YYYY" format. I'm passing date as "YYYY-MM-DD"

Here is the Query.

SELECT
  substr(PLACEMENT_DESC, 1, INSTR(PLACEMENT_DESC, '.', 1) - 1) AS "'Placement#'",
  SUM(VIEWS) AS "'Delivered_Impresion'",
  SUM(CLICKS) AS "'Clicks'",
  SUM(CONVERSIONS) AS "'Conversion'"
FROM TFR_REP.DAILY_SALES_MV
WHERE (IO_ID = {})
AND (DAY_DESC BETWEEN to_char(TO_DATE(TO_CHAR('{}'), 'MM/DD/YYYY'), 'YYYY-MM-DD')
AND to_char(TO_DATE(TO_CHAR('{}'), 'MM/DD/YYYY'), 'YYYY-MM-DD'))
GROUP BY PLACEMENT_ID,
         PLACEMENT_DESC
ORDER BY PLACEMENT_ID".format(self.config.IO_ID, self.config.SDATE, self.config.EDATE)

Here is the python Code: the code is too big, so I'm just putting a part of reading SQL.

from __future__ import print_function
import pandas as pd
import numpy as np
from xlsxwriter.utility import xl_rowcol_to_cell
import config
import pandas.io.formats.excel
pandas.io.formats.excel.header_style = None

        self.config=config

im not so familiar with panda, but could you print self.config.SDATE and self.config.EDATE, to see if they match the format you specified — Fire

Assuming that you are passing dates in "YYYY-MM-DD" format and DAY_DESC is date type, you could use date literals, which are ANSI standard and avoid TO_DATE

SELECT substr(PLACEMENT_DESC, 1, INSTR(PLACEMENT_DESC, '.', 1) - 1) AS "'Placement#'"
    ,SUM(VIEWS) AS "'Delivered_Impresion'"
    ,SUM(CLICKS) AS "'Clicks'"
    ,SUM(CONVERSIONS) AS "'Conversion'"
FROM TFR_REP.DAILY_SALES_MV
WHERE IO_ID = {}
    AND DAY_DESC BETWEEN DATE '{}'
        AND DATE '{}'
GROUP BY PLACEMENT_ID
    ,PLACEMENT_DESC
ORDER BY PLACEMENT_ID;

The table has a date column in "MM/DD/YYYY" format

Date datatypes don't have any formats in database. It is just the display that varies according to you session parameters. However, If you mean DAY_DESC is of string (CHAR/VARCHAR2)type, you could use it after converting it as:-

TO_DATE(DAY_DESC,'MM/DD/YYYY') BETWEEN DATE '{}' AND DATE '{}'

Please avoid storing dates as character strings in databases.
