How can I insert data from this loop in sqlite

sqlite insert
sqlite for loop
sqlite insert array of values
sqlite insert from another table
sqlite insert multiple rows
python sqlite insert multiple rows
sqlite insert python
python sqlite insert variables

I am trying to insert data from a loop that is similar to this.

import sqlite3
conn = sqlite3.connect('database.db')
c = conn.cursor()

words = ["apple", "banana", "cherry"]
for word in words:
     c.execute("insert into Words (word), values (?)",(word))
     print(word) 
     conn.commit

c.close()
conn.close()

Expected result is similar to this:

I am getting an error. But I am not sure how to correctly format this code right.

The error:

Traceback (most recent call last):
  File "file.py", line 7, in <module>
    c.execute("insert into Words (word), values (?)",(word))
sqlite3.OperationalError: near ",": syntax error

wrong list : commit() not commit because it is a method "insert into Words (word) values (?)",(word,) not "insert into Words (word), values (?)",(word)

right code is:

import sqlite3
conn = sqlite3.connect('database.db')
c = conn.cursor()

words = ["apple", "banana", "cherry"]
for word in words:
    c.execute("insert into Words (word) values (?)",(word,))
    print(word) 
conn.commit()
conn.close()

Don't worry, happy codding

SQLite Insert Into - Inserting New Rows Into a Table, To insert data into a table, you use the INSERT statement. SQLite provides various forms of the INSERT statements that allow you to insert a single row, multiple� Following are the two basic syntaxes of INSERT INTO statement. INSERT INTO TABLE_NAME [ (column1, column2, column3,columnN)] VALUES (value1, value2, value3,valueN); Here, column1, column2,columnN are the names of the columns in the table into which you want to insert data. You may not need to specify the column (s) name in the SQLite query if you are adding values for all the columns of the table.

I'm guessing you're getting an error because you can't place a single item in parenthesis to make it a tuple - so (word) isn't the way to go. It should be one of these (whichever one is more readable to you):

c.execute("insert into Words (word) values (?)",(word,))

Notice the comma inserted after word to make it a tuple. Or:

c.execute("insert into Words (word) values (?)",[word])

Which would make word the only element in a list

You can see for yourself in the console that doing something like ('hello') isn't equal to ('hello',). The first one remains a string, the second one is a tuple (which is what's needed in your command).

Edit: Also, you had a comma in that command that shouldn't be there

Does SQLite support loops and functions?, SQLite does not support functions, but it does do loops of a sort. INSERT INTO t VALUES (i) Originally Answered: Is SQLite a support loop and function? First, connect to the SQLite database by creating a Connection object. Second, create a Cursor object by calling the cursor method of the Connection object. Third, execute an INSERT statement. If you want to pass arguments to the INSERT statement, you use the question mark (?) as the placeholder for each argument.

The easiest way is to use f-string:

c.execute(f"INSERT INTO Words (word), values ({word})")

This is much easier to read :) but requires python 3.6+

import sqlite3

with sqlite3.connect('database.db') as conn:
    c = conn.cursor()

    words = ["apple", "banana", "cherry"]
    for word in words:
         c.execute(f"INSERT INTO Words (word), values ({word})")
         print(word) 
         conn.commit()

Update a sqlite database while select into a while loop, if you don't want to move to a real SQL database, and temporarily storing the result is not possible, you'll have to make sure you don't run concurrent SELECT � Using the INSERT statement in SQL, a row of data can be inserted into an SQLite table. INSERT SQL statement has several variants. All those variants of the INSERT statement begin with the form INSERT INTO <table_name>. Fig: Variants of INSERT statement supported by SQLite. Variant 1: INSERT INTO <table_name> values (<list of values>):

Python SQLite - Insert Data, Python SQLite - Insert Data - You can add new rows to an existing table of SQLite using the INSERT INTO statement. In this, you need to specify the name of the� The app starts off with an empty list of pets/inventories. As we add to the inventory, DB is populated. We can add dummy data to the list, add a new record of a pet, or edit an already existing entry.

Insert values in multiple tables SQLite in a single for loop , Is there a way to insert all those values in a SQLite data base in a single loop? I' ve wrote as much loops as tables I have with the same structure� This can be recast into SQLite as: INSERT INTO 'tablename' SELECT 'data1' AS 'column1', 'data2' AS 'column2' UNION ALL SELECT 'data1', 'data2' UNION ALL SELECT 'data1', 'data2' UNION ALL SELECT 'data1', 'data2' a note on performance. I originally used this technique to efficiently load large datasets from Ruby on Rails.

Dynamically Inserting into a Database with SQLite, Then, we use a one-liner for-loop to run dynamic_data_entry() ten times. This gives us the current time, converted to datestamp, and then a random value for the� The INSERT works on a single table, and can both insert one row at a time or many rows at once using a SELECT command. This statement is a part of the SQL Data Manipulation Language, DML. Syntax: INSERT [OR conflict-algorithm] INTO [database-name .] table-name [(column-list)] VALUES (value-list) Here we will create a new table prod_mast:

Comments
  • Still getting same error on both c.execute("insert into Words (word), values (?)",(word,)) sqlite3.OperationalError: near ",": syntax error
  • @ned sorry i edited that, that comma isn't needed, try again with the updated code
  • this will work, but in my experience it's a really bad idea to use f-stings on sqlite commands (not to mention is will be really difficult for large numbers of values)
  • Not in what I have tried as it leaves SQL code looking SQL. All the ? ? ? are easy to mix up.
