Setting sqlite I/O priority from python module (speeding up sqlite commits)

may help you . Have you tried 3.7's WAL? Historically, SQLite has been very slow at handling safe writes (eg. without changing to synchronous=off). It wrote the entire transaction to a journal, flushed it to disk, then copied the whole thing back over the original file, with many blocking syncs happening in between, serializing the whole thing.

tty Python Sqlite app: Noob NameError, Unexpected EOF, and sqlite error
Date : March 29 2020, 07:55 AM
I wish this help you You'll want raw_input instead of input in your script. input evaluates what you type, which is why you have to enter quotes. You can markdown code using the {} buttons above the input window. That actual markdown for code is a preceding 4 spaces. >>> import pythonmakenote
>>> pythonmakenote.mn()
>>> from pythonmakenote import mn
>>> mn()
db.execute('INSERT INTO note (note_txt) VALUES (?)', notetxt)
db.execute('INSERT INTO note (note_txt) VALUES (?)', (notetxt,))
import sys
import sqlite3
def mn():
conn = sqlite3.connect('data.db')
db = conn.cursor()
db.execute('select tag_text from tag')
tagssofar = db.fetchall()
print tagssofar
print "Enter note text, remember to let console wrap long lines"
notetxt = raw_input("note: ")
print "Enter 1 or more tags separated by spaces"
taglist = raw_input("tags: ")
taglist = taglist.split()
db.execute('INSERT INTO note (note_txt) VALUES (?)', [notetxt])
conn.commit()
db.execute('select last_insert_rowid()')
fknote = db.fetchone()[0]
print fknote
#records new tags since db trigger stops dups, updates many-many tbl
for tagtxt in taglist:
db.execute('INSERT INTO tag VALUES (?)',[tagtxt])
conn.commit()
db.execute('select rowid from tag where tag_text = (?)',[tagtxt])
fktag = db.fetchone()[0]
print fktag
db.execute('INSERT INTO fkeys VALUES (?,?)',[fknote,fktag])
conn.commit()

Python, Sqlite - how to put an image stored (either as Blob or base64 string) in a sqlite DB on a tkinter Label
Date : March 29 2020, 07:55 AM
wish of those help You can use the following to turn it into an Image object which tkinter could then display through a label (or elsewhere) from a base64 string. from PIL import Image
import base64, io
# Get the base64 string
Image.open(io.BytesIO(base64.b64decode(data)))
