I have multiple list and i would like to insert the data that is stored in the list into the sqlite database.
My insert statement is:
c.executemany("INSERT INTO admin(class, level, registerNo, ic, name) VALUES(?, ?, ?, ?, ?)", (sclass, level, registerNo, ic, name))
But my error stated:
sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 5, and there are 10 supplied.

I have 5 character fields in my SQL database, but I am unable to insert rows into the table. I have no problem when I do in Access Database.
Here is the code for my Insert statement and the error I am getting:
f1=hostname; f2=p.Caption; f3=p.Version; f4="1998-10-01";f5="2018-11-01"
print(f1,'--',f2,'--',f3,'--',f4,'--',f5)
sql = "INSERT INTO software VALUES (%s, %s, %s, %s, %s)"
cursor.execute(sql, {f1,f2,f3,f4,f5})
Error Message:
cursor.execute(sql, (f1,f2,f3,f4,f5)) pyodbc.ProgrammingError: ('The
SQL contains 0 parameter markers, but 5 parameters were supplied',
'HY000')
Assuming you're using pyodbc, the parameter marker is a ?:
sql = "INSERT INTO software VALUES (?, ?, ?, ?, ?)"
I'm getting this Sqlite3 programming error: sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 2, and there are 0 supplied.
I'm not sure why. I have tried everything I can think of. Please assist.
Thanks!
import csv
import sqlite3
with sqlite3.connect("new.db") as connection:
c = connection.cursor()
employees = csv.reader(open("employees.csv", "rU"))
#c.execute("CREATE TABLE employees (firstname TEXT, lastname TEXT)")
c.executemany("INSERT INTO employees(firstname, lastname) values (?, ?)", employees)
c.executemany("INSERT INTO employees(firstname, lastname) values (?, ?)", employees)
You have two ?, but supplied only with employees => values (?, ?)", employees)
csv.reader yields a generator expression. Thus, you need to caste the result as a list:
c.executemany("INSERT INTO employees(firstname, lastname) values (?, ?)", list(employees))
employees needs to be a 2d list, some for each call of executemany. You can create is easily using a nested list comprehensions:
import csv
import sqlite3
with sqlite3.connect("new.db") as connection:
c = connection.cursor()
reader = csv.reader(open("employees.csv", "rU"))
employees = [[x for x in row] for row in reader]
c.executemany("INSERT INTO employees(firstname, lastname) values (?, ?)", employees)
Trying to take a piece of data from at table in the database and inserting it into another table:
Fetching the order total and assigning it to variable:
cursor.execute('''SELECT Price FROM Tracks WHERE TrackID = ?''', (trackChoice,))
ordertotal = str(cursor.fetchall())
Putting it into table:
cursor.execute('''INSERT INTO Orders(OrderID, Date, OrderTotal, CustomerID, TrackID) VALUES(?, ?, ?, ?, ?)''', (orderID, date,
ordertotal, customerID, trackChoice))
Error:
sqlite3.InterfaceError: Error binding parameter 2 - probably unsupported type.
With cursor.fetchall() you get all the rows in 'Tracks'. So it will have an ID and probably other informations as well. f.E. something like this: (1, 'William', 'Shakespeare', 'm', None, '1961-10-25'). What is 'ordertotal'? I guess it will be a number? If yes, and you are using sqlite3 you could use row_factory. See the answere here for more information: Get a list of field values from Python's sqlite3, not tuples representing rows
Why not just do:
cursor.execute("""
INSERT INTO Orders(name, Date, name, name, name)
VALUES(?, strftime('now'), ?, ?, ?)""",
(value, value, value, value);
That is, use the current time in the database.
(I assume that name is really four different columns or you should get another error.)
Trying to pass a variable (a set) into an sqlalchemy query.
Found this: How can I bind a list to a parameter in a custom query in sqlalchemy? But it requires you to know many items there are. The number of entries changes at any given moment.
My previous question went mostly unanswered unfortunately so I figured I'd re-iterate what I'm trying to do here.
Basically, I have this variable: sites = set(db1).intersection(db2) and I'm trying to pass it into this sql alchemy query:
'test': DBSession.query(A_School.cis_site_id.in_(sites)).all(),
But I get invalid syntax errors and invalid parameter type errors...I can't get this thing to do what I want it to do. DB1 and DB2 are, as you mightve guessed, 2 different databases.
db1 = cis_db.query(site.site_id).join(site_tag).filter(site_tag.tag_id.like(202)).all()
db2 = DBSession.query(A_School.cis_site_id).all()
Full error:
ProgrammingError: (ProgrammingError) ('Invalid parameter type. param-index=0 param-type=KeyedTuple', 'HY105') u'SELECT [A_School].cis_site_id IN (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) AS anon_1
FROM [A_School]' ((14639,), (14709,), (14587,), (14966,), (14625,), (14589,), (15144,), (15171,) ... displaying 10 of 18 total bound parameter sets ... (15133,), (14036,))
KeyedTuple is the type of each row returned by SQLAlchemy when not querying one full model. You are making sets of keyed tuples, rather than sets of the single value in each tuple. Should look something like this instead:
db1 = set(x.site_id for x in cis_db.query(site.site_id).join(site_tag).filter(site_tag.tag_id.like(202)))
db2 = set(x.cis_site_id for x in DBSession.query(A_School.cis_site_id))
sites = db1.intersection(db2)
test = DBSession.query(A_School).filter(A_School.cis_site_id.in_(sites)).all()
Assuming you would like to load schools for the sites, how about you try:
DBSession.query(A_School).filter(A_School.cis_site_id.in_(sites)).all()
instead of:
DBSession.query(A_School.cis_site_id.in_(sites)).all()
I have a tuple that i wanna store its elements, I'm trying to insert it as following and it gives the following error, what am i doing wrong ? records_to_be_inserted is the tuple that has 8 elements.
with self.connection:
cur = self.connection.cursor()
cur.executemany("INSERT INTO rehberim(names, phone, mobile, email, \
photo, address, note, date) VALUES(?, ?, ?, ?, ?, ?, ?, ?)", self.records_to_be_inserTed)
Traceback (most recent call last):
File "/home/tayfun/workspace/personal_guide/modules/mainwindow.py", line 57, in save_records
photo, address, note, date) VALUES(?, ?, ?, ?, ?, ?, ?, ?)", self.records_to_be_inserTed)
sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 8, and there are 0 supplied.
Note that the executemany is for inserting multiple rows, e.g.,
import sqlite3
""" the table structure is:
create table tab
a char(1),
b char(2),
c char(3)
)
"""
conn = sqlite3.connect('C:\\test.db')
stmt = "insert into tab (a, b, c) values (?, ?, ?)"
cur = conn.cursor()
## many rows
vals = [('1','2','3'), ('2','3','4'), ('3','4','5')]
cur.executemany(stmt, vals)
cur.close()
This will result in three rows in the database. If it is because you have multiple values in one query, you need to format it!
Edit: Added formatting with dictionaries
By using the following approach you do not need to consider the order of the values in the format call because the key in the dictionary is mapping the value into the {key_word} placeholder.
values = {'a' : 'value_a',
'b' : 'value_b'}
stmt = "insert into tab (col_a, col_b) values ({a}, {b})".format(**values)
The query must have all the data ready to be inserted.
You are calling a function in the query, which i guess you want that provides the data but that wont work.
You need to pass all the data in variables or locate them in the tuple index (like: tuple_name[1], tuple_name[4], etc.)
Example:
myTuple = ['a','b','c','d','e','f','g']
cur.executemany("INSERT INTO rehberim(names, phone, mobile, email, \
photo, address, note, date) VALUES({0}, {1}, {2}, {3}, {4}, {5}, {6}" .format (myTuple[1], myTuple[2], myTuple[3], myTuple[4], myTuple[5], myTuple[6], myTuple[7])
