Cannot INSERT strings with Set Clause with mariadb connector (python)

I want to insert a new row in my table by using the python-mariadb connector. For that I prefer to use the SET clause.
For some reason it does work if I only want to save ints (i.e y=2), but when I use a string, the following error occurs
Unknown column 'myString' in 'field list'
It seems it thinks the content of the string is a column name? Any idea how to fix that (I can do it with INSERT INTO ... VALUES ..., but I want to use the SET clause here). From my understanding, it should save both an int and a str without throwing an error
Thank you.
See the code example below
def myfunction():
x = 1
y ='myString'
db = connect_db()
cur = db.cursor()
sql = "INSERT INTO Table SET col1={}, col2={}"
cur.execute(sql.format(x, y))
db.commit()
db.close()
return
Here the MariaDB Connector, but this should be fine as it works for other db functions.
import mariadb
def connect_db():
db = mariadb.connect(
user="user",
password="123",
host="localhost",
port=3306,
database="DB"
)
db.autocommit = False
return db

you are not using right syntax for insert
sql = "INSERT INTO Table (col1,col2) values({}, {})"
but if you want to update an existing row:
sql = "UPDATE Table SET col1={}, col2={} WHERE id = {}"
and probably you need a where clause

The code in question produces the SQL statement:
INSERT INTO Table SET col1=1, col2=myString;
This is incorrect syntax, and strings must be in single-quotes:
INSERT INTO Table (col1, col2) VALUES (1, 'myString');
def myfunction():
x = 1
y ='myString'
db = connect_db()
cur = db.cursor()
sql = "INSERT INTO Table (col1, COL2) VALUES ({}, '{}')"
cur.execute(sql.format(x, y))
db.commit()
db.close()
return
But the above is fragile. Don't use string building methods to create SQL statements, it is much better to use parameter binding.
def myfunction():
x = 1
y ='myString'
db = connect_db()
cur = db.cursor()
sql = "INSERT INTO Table (col1, col2) VALUES (?, ?)"
cur.execute(sql, (x, y))
db.commit()
db.close()
return
The MariaDB connector documentation explains these things.
Retrieving Data
Once you have the initial code in place you can start working with the data. The first thing you should do is try to
retrieve information from the database. Here is code for a query
against the employees database:
cur.execute(
"SELECT first_name,last_name FROM employees WHERE first_name=?",
(some_name,))
MariaDB Connector/Python uses prepared statements, sanitizing and inserting the values from the tuple into the position
of the question marks (?). This is safer than inserting through
f-strings or format specifiers when working with user provided
information.
The query results are stored in a list in the cursor object. To view
the results, you can loop over the cursor.
Adding Data
Using the same execute() method with an INSERT statement, you can add rows to the table.
cursor.execute(
"INSERT INTO employees (first_name,last_name) VALUES (?, ?)",
(first_name, last_name))

How to get id of newly created record -Postgresql-Flask?

I am trying to insert a new row into postgresql database using psycopg2 and flask.
Here is the code:
con = psycopg2.connect("host=localhost dbname=crm_whatsapp user=user_name password=user_password")
cur = con.cursor()
create = cur.execute("INSERT INTO crm_user_chat_data (number) VALUES (%s) returning id",(user_number,)) //Here it returns none
con.commit()
But I am getting None instead of id.
How can i solve this?

You need to fetch() from the cursor to get the id:
cur = con.cursor()
create = cur.execute("INSERT INTO crm_user_chat_data (number) VALUES (%s) returning id",(user_number,))
con.commit()
insertId = cur.fetchone()

Python - INSERT table INTO SQLite from MS SQL Server

I am trying to query MS SQL Server for a table.column, then insert this output into a sqlite table.
This example has one numeric column in the SQL Server source table.
I think I've almost got it by scouring the other answers.
Please let me know what I am missing.
import sqlite3
import pyodbc
#def connect_msss():
ODBC_Prod = ODBC_Prod
SQLSN = SQLSN
SQLpass = SQLpass
conn_str = ('DSN='+ODBC_Prod+';UID='+SQLSN+';PWD='+SQLpass)
conn = pyodbc.connect(conn_str)
#def connect_sqlite():
sl3Conn = sqlite3.connect('server_test.db')
c = sl3Conn.cursor()
c.execute('CREATE TABLE IF NOT EXISTS mrn_test (PTMRN NUMERIC)')
#def query_msss():
cur = conn.cursor()
cur.execute("SELECT TOP 50 PTMRN FROM dbo.atl_1234_mrntest")
rows = cur.fetchall()
for row in rows:
c.execute("INSERT INTO mrn_test VALUES (?)", row)
conn.commit()
#connect_msss()
#connect_sqlite()
#query_msss()
Error 1:
c.execute('CREATE TABLE IF NOT EXISTS mrn_test
(PTMRN NUMERIC)')
Out[117]: <sqlite3.Cursor at 0x2d1a742fc70>
Error 2:
cur = conn.cursor() cur.execute("SELECT TOP 50 PTMRN FROM
dbo.atl_1234_mrntest")
Out[118]: <pyodbc.Cursor at 0x2d1a731b990>

You're not committing the executed changes on the sqlite connection, after the c.execute step you're committing the MySQL DB connection. I think you need to replace conn.commit() at the end with sl3Conn.commit().

Export specific column from one database to another one

I want to export specific column from one database to another one using Python but its not coming:
# Display all Non-Duplicate data
import sqlite3
import csv
conn = sqlite3.connect('data.db')
# STEP 2 : create a small data file with only three fields account_id, product_id and unit_quantity
cursor = conn.execute("SELECT field1,field12,field14 FROM database")
for row in cursor:
print row[0:11]
print "Operation done successfully";
conn.close()

Create second connection and insert directly
conn = sqlite3.connect('data.db')
cursor = conn.execute("SELECT field1,field12,field14 FROM database")
export = sqlite3.connect('exported.db')
#get result as list
for values in cursor.fetchall():
export.execute('INSERT INTO tablename(field1,field12,field14) VALUES (%s, %s, %s)' % (values[0], values[1], values[2]))
export.commit()
export.close()

Problem with inserting into MySQL database from Python

I am having trouble inserting a record into a MySQL database from python. This is what I am doing.
def testMain2():
conn = MySQLdb.connect(charset='utf8', host="localhost", user="root", passwd="root", db="epf")
cursor = conn.cursor()
tableName = "test_table"
columnsDef = "(export_date BIGINT, storefront_id INT, genre_id INT, album_id INT, album_rank INT)"
exStr = """CREATE TABLE %s %s""" % (tableName, columnsDef)
cursor.execute(exStr)
#Escape the record
values = ["1305104402172", "12", "34", "56", "78"]
values = [conn.literal(aField) for aField in values]
stringList = "(%s)" % (", ".join(values))
columns = "(export_date, storefront_id, genre_id, album_id, album_rank)"
insertStmt = """INSERT INTO %s %s VALUES %s""" % (tableName, columns, stringList)
cursor.execute(insertStmt)
cursor.close()
conn.close()
The table is created however nothing is in the table. I can run the INSERT statement successfully in Terminal with the same credentials.
Any suggestions on what I may be doing wrong?

You haven't committed the transaction.
conn.commit()
(The MySQLdb library sets autocommit to False when connecting to MySQL. This means that you need to manually call commit or your changes will never make it into the database.)
