)
# print(mydb)
# # To Create Database
mycursor = mydb.cursor()
# creating column list for insertion#BSIT(M)-VII
print(data.columns.tolist())
cols = "`,`".join([str(i) for i in data])
for i,row in data.iterrows():
sql = "INSERT INTO `room` (`" +cols + "`) VALUES (" + "%s,"*(len(row)-1) + "%s)"

How to pass multiple variables as values in second sqlite execute argument

I have a database, and I wish to add multiple values to the same row. I am somewhat new with sqlite and databases, but I am learning. I know I can do this:
conn = sqlite3.connect('sqlitedb.db')
c = conn.cursor()
c.execute('CREATE TABLE IF NOT EXISTS threadTable(threadName varchar(30)')
c.execute('INSERT INTO threadTable (threadName) Values(?), x.Name')
This works for me, but I want to pass Multiple variables into the table, like so:
conn = sqlite3.connect('sqlitedb.db')
c = conn.cursor()
c.execute('CREATE TABLE IF NOT EXISTS threadTable(threadName varchar(30),threadKey varchar(10),threadID varchar(1000))')
c.execute('INSERT INTO threadTable (threadName),(threadKey),(threadID) VALUES(?,?,?)', (x.Name, x.Key, x.ID))
When I try this, I get this error:
Traceback (most recent call last):
File "Files/main.py", line 39, in <module>
c.execute('INSERT INTO threadTable (threadName),(threadKey),(threadID) VALUES(?,?,?)', (x.Name, x.Key, x.ID))
sqlite3.OperationalError: near ",": syntax error

you don't need parantheses around each column :
c.execute('INSERT INTO threadTable (threadName,threadKey,threadID) VALUES(?,?,?)', (x.Name, x.Key, x.ID))

sqlite3 database query in python

I tried performing a search query from the backend of an app I'm working and I got the response below:
Traceback (most recent call last):
File "backend.py", line 30, in search
cur.execute("SELECT * FROM PlanInfo WHERE Location=?", self.NmRqst.text)
ValueError: parameters are of unsupported type
I have the code below:
def connectfile(self):
conn = sqlite3.connect("TestTrace.db")
cur = conn.cursor()
cur.execute(
"CREATE TABLE IF NOT EXISTS PlanInfo (Plan Number TEXT, Tracing Number TEXT, Submitted By TEXT, "
"Location TEXT)")
conn.commit()
conn.close()
def search(self):
conn = sqlite3.connect("TestTrace.db")
cur = conn.cursor()
cur.execute("SELECT * FROM PlanInfo WHERE Location=?", self.NmRqst.text)
rows = cur.fetchall()
conn.close()
return rows
self.NmRqst.text is the QLineEdit that accepts the user input for database query...
Feel free to correct the question as you deem fit!
I have edited the lines of code,
def connectfile(self):
conn = sqlite3.connect("TestTrace.db")
cur = conn.cursor()
cur.execute(
"CREATE TABLE IF NOT EXISTS PlanInfo (Plan_Number TEXT, Tracing_Number TEXT, Submitted_by TEXT, "
"Location TEXT)")
conn.commit()
conn.close()
def search(self):
conn = sqlite3.connect("TestTrace.db")
cur = conn.cursor()
cur.execute("SELECT * FROM PlanInfo WHERE Location=?", str(self.NmRqst.text,))
rows = cur.fetchall()
conn.close()
return rows
...and I got the following error:
Traceback (most recent call last):
File "backend.py", line 30, in search
cur.execute("SELECT * FROM PlanInfo WHERE Location=?", str(self.NmRqst.text,))
sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 1, and there are 64 supplied.

sqlite3.OperationalError: no such table: store

I'm learning sqlite3 with python, but I've been facing this error: "sqlite3.OperationalError: no such table: store". How do I get around this?
import sqlite3
def create_table(): #function to create the table
conn = sqlite3.connect('lite.db')
cur = conn.cursor() # creating th cursor object
cur.execute("CREATE TABLE IF NOT EXISTS store (item TEXT, quantity INTEGER, price REAL)")
conn.commit()
conn.close()
def insert(item, quantity, price ): #function to insert into the table
conn = sqlite3.connect('lite.db')
cur = conn.cursor() # creating th cursor object
cur.execute("INSERT INTO store VALUES(?,?,?)", (item, quantity, price))
conn.commit()
conn.close()
insert("biscuits",500,20000)
def view():
conn = sqlite3.connect('lite.db')
cur = conn.cursor()
cur.execute("SELECT * FROM store")
rows = cur.fetchall()
return rows
conn.close()
print(view())

You forgot to call the create_table method before calling insert. As you haven't called the the create_table method the insert method tries to insert a record to a non existing table.
The solution is simply to call the create_table method before insert as follows:
create_table() # Add this line before the insert
insert("biscuits", 500, 20000)

opening and closing mysql connection

I have this python function:
import MySQLdb as mdb
def sql_query(sql):
try:
con = mdb.connect('localhost', 'user', '', 'dbs')
with con:
cur = con.cursor()
cur.execute(sql)
results = cur.fetchall()
return results
except mdb.Error, e:
sys.exit(1)
finally:
if con:
con.close()
then i have loads of code that calls this function, sometime the con closes and i get this traceback:
Traceback (most recent call last):
File "users.py", line 431, in <module>
orders = get_orders(user_id, mongo_user_id, address_book_list)
File "users.py", line 343, in get_orders
order_lines = get_order_lines(order_id)
File "users.py", line 288, in get_order_lines
for item in sql_query(get_order_lines_sql):
File "users.py", line 57, in sql_query
if con:
UnboundLocalError: local variable 'con' referenced before assignment
where my get_orders code is like:
def get_orders(user_id, mongo_user_id, address_book_list):
# we just want orders that are less than 2 years old
get_orders_sql = """SELECT order_id, state, state2, stamp, reference, comments, address_id, delivery_id, user_id FROM user_orders WHERE address_id IS NOT NULL and stamp >= '2012-01-01 00:00:00' and user_id='%s' ORDER BY stamp DESC"""% (user_id)
# delivery_id - this is the shipping option the user chose.
for items in sql_query(get_orders_sql):
#print items
order_id = items[0]
there is about 50K rows in the orders
any advice much appreciated

you need to initialize con since let say there was error in mdb.connect your get error when it some how reaches final your con is still un initialized
import MySQLdb as mdb
def sql_query(sql):
con='' #this should be intiated
try:
con = mdb.connect('localhost', 'user', '', 'dbs')
with con:
cur = con.cursor()
cur.execute(sql)
results = cur.fetchall()
return results
except mdb.Error, e:
sys.exit(1)
finally:
if con:
con.close()
