Python - Reading FileStream data from SQL Server into memory then output to file -


i trying load in filestream data sql server (via stored proc) , taking byte data , outputting file on disk. need work python 2.7

here have far:

import pymssql  def read_blob(filedetailid):     conn = pymssql.connect(host="localhost",database="mydb")     query = "ops.loadfileblobfromsqlextended '" + filedetailid + "'"     cursor = conn.cursor()     cursor.execute(query)     row = cursor.fetchone()     blobfiledata = row[3]     filedirectory = 'c:/test/'     filename = row[4] + row[5]     write_file(blobfiledata, filedirectory + filename)     conn.commit()    def write_file(data, filename):     open(filename, 'wb') f:         f.write(data)   read_blob("1")

i file in directory want , stream of data in row[3] empty shell of file output.

i know missing simple... don't know what.

here equivalent c# code work (i think missing sqlfilestream part in python code)

private static object streamfileobjecttofilefromsqlfilestream(string serverpath, byte[] servertxn, string filedirectory, string filename, string filextension) {     using (sqlfilestream sfs = new sqlfilestream(serverpath, servertxn, fileaccess.read))     {         using (filestream fs = new filestream(filedirectory + filename + filextension, filemode.create))         {             sfs.copyto(fs);         }     }     return null; }

any ideas?

thanks,

corey
