Getting an error on sending an embed message of the player/user's balance

The following is the code that has to do with the balance, as u might notice that there are various currencies and for that I have done add_field quite a few times, it would be really nice if you could tell me if there is a way to do it in a shorter and/or easier way...anyways coming to the main problem.
Main.py
async def equilibrium(user: discord.Member):
db = await aiosqlite.connect("balance_db.db")
cursor = await db.cursor()
await cursor.execute(f"SELECT * FROM bal WHERE user_id = {user.id} ")
result = await cursour.fetchall()
print (result)
if result:
return
if not result:
await cursor.execute(f"INSERT INTO bal(user_id, cash, crystals, event_pearls, weapon_shards, fusion_earring, merging_stones, enhancing_stones) VALUES (?, ?, ?, ?, ?, ?, ?, ?)", (user.id, 500, 0, 0, 0, 0, 0, 0, 0))
await db.commit()
await cursor.close()
await db.close()
#bot.command(aliases=['bal'])
async def balance(ctx, user:discord.Member=None):
if user is None:
user = ctx.author
await equilibrium(user=user)
db = await aiosqlite.connect("balance_db.db")
cursor = await db.cursor()
await cursor.execute(f"SELECT * FROM bal WHERE user_id = {user.id} ")
balem = discord.Embed(title=f"**{user.mention}'s balance**", color=discord.Color.blue())
balem.add_field(name="Cash:", value=f":GenesisCrystal: {result[1]}", inline=True)
balem.add_field(name="crystals:", value=f":GenesisCrystal: {result[2]}", inline=True)
balem.add_field(name="event pearls:", value=f":GenesisCrystal: {result[3]}", inline=True)
balem.add_field(name="weapon shards:", value=f":GenesisCrystal: {result[4]}", inline=True)
balem.add_field(name="fusion earring:", value=f":GenesisCrystal: {result[5]}", inline=True)
balem.add_field(name="merging stones:", value=f":GenesisCrystal: {result[6]}", inline=True)
balem.add_field(name="enhancing stones:", value=f":GenesisCrystal: {result[7]}", inline=True)
await ctx.send(embed=balem)
upon testing and doing '(serverprefix) bal' it gives the following error:

The Bot is Online
I am using the following:
python version 9.3x (9.3.13 precisely)
aiosqlite as the database (i know about the mordern aiosqlite method of writing the code, but I am much more familiar with the old, or the sqlite3 method
I am just a beginner, help of any kind would be appriciated

Looks like you need to change result = await cursor.fetchall() to result = await cursour.fetchall()[0].
Sqlite's fetchall() returns a list of tuples (something like [(1,), (2,)], so you need to index to the first tuple, then loop through that.

Discord.py and SQL - Comparing between 2 tables in the same database file

So I have two tables, Servers and Strikes. In the Servers table, I have a max strikes value. I want to compare the strikes a user has to the max strikes specified in the Servers table. I tried this:
#commands.command(name='strike', pass_ctx= True)
#commands.has_permissions(manage_messages=True)
async def strike(self, ctx, member : discord.Member):
first_strike = 1
cursor = await self.client.db.cursor()
await cursor.execute(f"SELECT Strikes_Have FROM Strikes WHERE Guild_ID = {ctx.guild.id} AND User_ID = {member.id}")
result = await cursor.fetchone()
if result == None:
cursor = await self.client.db.cursor()
sql = f"INSERT INTO Strikes(Guild_ID, User_ID, Strikes_Have) VALUES({ctx.guild.id}, {member.id}, {first_strike})"
else:
cursor = await self.client.db.cursor()
sql = f"UPDATE Strikes SET Strikes_Have = Strikes_Have + 1 where Guild_ID = {ctx.guild.id} AND User_ID = {member.id}"
if result["Strikes_Have"] == result["MAX_STRIKES"]:
await ctx.message.channel.send(f"{member} has the max amount of stirkes specified by the server")
await cursor.execute(sql)
await self.client.db.commit()
await cursor.close()
await ctx.message.channel.send(f"Striked {member}")`
But got this error:
Traceback (most recent call last):
File "/home/pi/.local/lib/python3.7/site-packages/discord/ext/commands/core.py", line 85, in wrapped
ret = await coro(*args, **kwargs)
File "/home/pi/EndorCore/cogs/Mod.py", line 225, in strike
if result["Strikes_Have"] == result["MAX_STRIKES"]:
IndexError: No item with that key

The error message you're getting currently is being caused by you trying to access a column of data which doesn't exist in the strikes table.
To get the max strikes value, you need to query that table and get the number, then compare the two.
For example:
cursor.execute(f"SELECT Strikes_Have FROM Strikes WHERE Guild_ID = {ctx.guild.id} AND User_ID = {member.id}")
user_result = cursor.fetchone()
cursor.execute(f"SELECT MAX_STRIKES FROM Servers WHERE Guild_ID = {ctx.guild.id}")
server_result = cursor.fetchone()
if user_result["Strikes_Have"] == server_result['MAX_STRIKES']:
print("User has max strikes")

How to store speacial symbols in SQLITE

This is my table
#client.event
async def on_ready():
db = sqlite3.connect('Smilewin.sqlite')
cursor = db.cursor()
cursor.execute('''
CREATE TABLE IF NOT EXISTS Introduce(
guild_id TEXT,
channel_id TEXT,
boarder TEXT,
status TEXT
)
''')
I wanted to store anything from a normal text to something like this ☆ﾟ ゜ﾟ☆ﾟ ゜ﾟ☆ﾟ ゜ﾟ☆ﾟ ゜ﾟ☆ﾟ ゜ﾟ☆
(basically anything)
When I try to store ☆ﾟ ゜ﾟ☆ﾟ ゜ﾟ☆ﾟ ゜ﾟ☆ﾟ ゜ﾟ☆ﾟ ゜ﾟ☆ It is giving an error.
Traceback (most recent call last):

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'str' object has no attribute 'text'
The code which I use to store that special symbols is:
#client.command()
#commands.has_permissions(administrator=True)
async def setboarder(ctx, *,boarder):
db = sqlite3.connect('Smilewin.sqlite')
cursor = db.cursor()
cursor.execute(f"SELECT boarder FROM Introduce WHERE guild_id = {ctx.guild.id}")
result = cursor.fetchone
if result is None:
sql = ("INSERT INTO Introduce(guild_id, boarder) VALUES(?,?)")
val = (ctx.guild.id , boarder)
embed = discord.Embed(
colour= 0x00FFFF,
title = "ตั้งค่ากรอบเเนะนําตัว",
description= f"กรอบได้ถูกตั้งเป็น {boarder}"
)
message = await ctx.send(embed=embed)
await message.add_reaction('✅')
elif result is not None:
sql = ("UPDATE Introduce boarder = ? WHERE guild_id = ?")
val = (boarder , ctx.guild.id)
embed = discord.Embed(
colour= 0x00FFFF,
title = "ตั้งค่ากรอบเเนะนําตัว",
description= f"กรอบได้ถูกอัพเดตเป็น {boarder}"
)
message = await ctx.send(embed=embed)
await message.add_reaction('✅')
cursor.execute(sql, val)
db.commit()
cursor.close()
db.close()
I want to know is it possible to store that kind of data in sqlite. If yes how can I do it please provide some example. thank you so much

There is an error in your update query which may or may not have some bearing on the problem.
"UPDATE Introduce boarder = ? WHERE guild_id = ?"
is missing the keyword SET. The statement should be:
"UPDATE Introduce SET boarder = ? WHERE guild_id = ?"
I don't see how the exception traceback relates to this problem. It also seems unrelated to whether the db can store your unicode strings; it can.
Try fixing this bug and see how you go.

How can i create a table on my sqlite database?

Thats my first python sql and im trying to code this bot i got this error:
SQL CODE
import sqlite3
...
#commands.Cog.listener()
async def on_message(self, message):
db = sqlite3.connect('banco.sqlite')
cursor = db.cursor()
cursor.execute(f'SELECT nome FROM banco WHERE nome = "{message.author.id}"')
result = cursor.fetchone()
if result is None:
sql = ('INSERT INTO banco(nome, dinheiro) VALUES(?, ?)')
val = (message.author.id, 0)
cursor.execute(sql, val)
db.comit()
cursor.close()
ERROR:
File "/Users/CIP/Documents/GitHub/economia/cogs/dinheiro.py", line 54, in on_message
cursor.execute(f'SELECT column1 FROM banco WHERE column1 = "{message.author.id}"')
sqlite3.OperationalError: no such table: banco
LINE 54
cursor.execute(f'SELECT nome FROM banco WHERE nome = "{message.author.id}"')

Auto reconnect postgresq database

I have the following code:
import psycopg2
conn = psycopg2.connect(database="****", user="postgres", password="*****", host="localhost", port="5432")
print ("Opened database successfully")
cur = conn.cursor()
cur.execute('''select * from xyz''')
print ("Table created successfully")
conn.commit()
conn.close()
Like this i have some 50 -60 complex queries, but problem is some times the postgre sql Database throws the below error
Traceback (most recent call last):
File "C:/Users/ruw2/Desktop/SQL.py", line 87, in <module>
cur.execute('''select * from xyz;''')
psycopg2.DatabaseError: server conn crashed?
server closed the connection unexpectedly.
This probably means the server terminated abnormally before or while processing the request.
Looks like the connection is lost, how can i auto connect the Postgre database
Appreciate your help

I would rely on decorators - retry and reconnect:
import psycopg2
from tenacity import retry, wait_exponential, stop_after_attempt
from typing import Callable
def reconnect(f: Callable):
def wrapper(storage: DbStorage, *args, **kwargs):
if not storage.connected():
storage.connect()
try:
return f(storage, *args, **kwargs)
except psycopg2.Error:
storage.close()
raise
return wrapper
class DbStorage:
def __init__(self, conn: string):
self._conn: string = conn
self._connection = None
def connected(self) -> bool:
return self._connection and self._connection.closed == 0
def connect(self):
self.close()
self._connection = psycopg2.connect(self._conn)
def close(self):
if self.connected():
# noinspection PyBroadException
try:
self._connection.close()
except Exception:
pass
self._connection = None
#retry(stop=stop_after_attempt(3), wait=wait_exponential())
#reconnect
def get_data(self): # pass here required params to get data from DB
# ..
cur = self._connection.cursor()
cur.execute('''select * from xyz''')
# ..

Catch the exception and reconnect:
while True:
conn = psycopg2.connect(database="****", user="postgres", password="*****", host="localhost", port="5432")
cur = conn.cursor()
try:
cur.execute('''select * from xyz''')
except psycopg2.OperationalError:
continue
break;
