Store XML File into MS SQL DB using Python
Question:
My MSSQL DB table contains following structure:
create table TEMP
(
MyXMLFile XML
)
Using Python, I a trying to load locally stored .XML file into MS SQL DB (No XML Parsing Required)
Following is Python code:
import pyodbc
import xlrd
import xml.etree.ElementTree as ET
print("Connecting..")
# Establish a connection between Python and SQL Server
conn = pyodbc.connect('Driver={SQL Server};'
'Server=TEST;'
'Database=test;'
'Trusted_Connection=yes;')
print("DB Connected..")
# Get XMLFile
XMLFilePath = open('C:HelloWorld.xml')
# Create Table in DB
CreateTable = """
create table test.dbo.TEMP
(
XBRLFile XML
)
"""
# execute create table
cursor = conn.cursor()
try:
cursor.execute(CreateTable)
conn.commit()
except pyodbc.ProgrammingError:
pass
print("Table Created..")
InsertQuery = """
INSERT INTO test.dbo.TEMP (
XBRLFile
) VALUES (?)"""
# Assign values from each row
values = (XMLFilePath)
# Execute SQL Insert Query
cursor.execute(InsertQuery, values)
# Commit the transaction
conn.commit()
# Close the database connection
conn.close()
But the code is storing the XML path in MYXMLFile column and not the XML file. I referred lxml
library and other tutorials. But, I did not encountered straight forward approach to store file.
Please can anyone help me with it. I have just started working on Python.

Here, is solution to load .XML file directly into MS SQL SB using Python.
import pyodbc
import xlrd
import xml.etree.ElementTree as ET
print("Connecting..")
# Establish a connection between Python and SQL Server
conn = pyodbc.connect('Driver={SQL Server};'
'Server=TEST;'
'Database=test;'
'Trusted_Connection=yes;')
print("DB Connected..")
# Get XMLFile
XMLFilePath = open('C:HelloWorld.xml')
x = etree.parse(XBRLFilePath) # Updated Code line
with open("FileName", "wb") as f: # Updated Code line
f.write(etree.tostring(x)) # Updated Code line
# Create Table in DB
CreateTable = """
create table test.dbo.TEMP
(
XBRLFile XML
)
"""
# execute create table
cursor = conn.cursor()
try:
cursor.execute(CreateTable)
conn.commit()
except pyodbc.ProgrammingError:
pass
print("Table Created..")
InsertQuery = """
