connection = request.form.get('connection_type_id') was this supposed to be connection_type_id = ....? request.form is by default ImmutableMultiDict with form data, your connection variable is set to form element with name connection_type_id, that's why you are getting error. I assume connection is mysql connection object from global space.
Please change to connection_type_id = request.form.get('connection_type_id') and it's references as well.

I am making a login and registration project. The login code looks similar to this where the query is obviously not an insert statement. This is the registration code below to register a user. The front end sends their json to me as a back end and I parse it. I remember this was working yesterday. Now today, I've noticed it's not inserting data into the database, yet I am getting the true response that it inserted. I check the table and nothing is getting inserted.
def auth(n):
cnx = mysql.connector.connect(user='dbuser', password='dbpass', host='localhost', port='3306', database='dbname')
cursor = cnx.cursor(buffered = True)
value_list = list()
for value in n.values():
value_list.append(value)
value_string = str(value_list)
a = value_string.strip("[")
b = a.strip("]")
c = b.replace("'", "")
d = c.split(', ')
authquery=("INSERT INTO members (id, firstname, lastname, email, password, history) VALUES (id, %s, %s, %s, %s);")
cursor.execute(authquery, d)
if cursor.rowcount:
return "true"
else:
return "false"
cursor.close()
cnx.commit()
cnx.close()
Anyone know why it is doing this? I even tried creating a new table and even a new database.
I am using pandas.to_sql to insert rows into tables. I read that SQLAlchemy released an option of fast_executemany for mssql+pyodbc connections. I wanted to know if there is something similar I can use for MySQL?
My current code:
dstConn = create_engine('mysql+mysqlconnector://{}:{}#{}:{}/{}'.format(user, pwd, dbServer, PORT, dbName),
echo=False, pool_size=10, max_overflow=20)
for items in pd.read_sql(sqlFrom, con = origConn, chunksize = 2000):
items = items.rename(columns = rename_cols)
table_name = 'mytable'
items.reindex(columns = get_dst_colums).to_sql
(name = table_name, con = dstConn, if_exists = 'append', index = False, method = None)
In pandas official docs for to_sql there is another argument called - method which is default None. I wanted to know if I set that to Multi would I receive any speed up for the above inserts?
First of all, sorry for my lack of knowledge regarding databases, this is my first time working with them.
I am having some issues trying to get the data from an excel file and putting it into a data base.
Using answers from the site, I managed to kind of connect to the database by doing this.
import pandas as pd
import pyodbc
server = 'XXXXX'
db = 'XXXXXdb'
# create Connection and Cursor objects
conn = pyodbc.connect('DRIVER={SQL Server};SERVER=' + server + ';DATABASE=' + db + ';Trusted_Connection=yes')
cursor = conn.cursor()
# read data from excel
data = pd.read_excel('data.csv')
But I dont really know what to do now.
I have 3 tables, which are connected by a 'productID', my excel file mimics the data base, meaning that all the columns in the excel file have a place to go in the DB.
My plan was to read the excel file and make lists with each column, then insert into the DB each column value but I have no idea how to create a query that can do this.
Once I get the query I think the data insertion can be done like this:
query = "xxxxxxxxxxxxxx"
for row in data:
#The following is not the real code
productID = productID
name = name
url = url
values = (productID, name, url)
cursor.execute(query,values)
conn.commit()
conn.close
Database looks like this.

EDIT:
Tried doing something like this, but i'm getting 'not all arguments converted during string formatting' Type error.
import pymysql
import pandas as pd
connStr = pymysql.connect(host = 'xx.xxx.xx.xx', port = xxxx, user = 'xxxx', password = 'xxxxxxxxxxx')
df = pd.read_csv('GenericProducts.csv')
cursor = connStr.cursor()
query = "INSERT INTO [Productos]([ItemID],[Nombre])) values (?,?)"
for index,row in df.iterrows():
#cursor.execute("INSERT INTO dbo.Productos([ItemID],[Nombre])) values (?,?,?)", row['codigoEspecificoProducto'], row['nombreProducto'])
codigoEspecificoProducto = row['codigoEspecificoProducto']
nombreProducto = row['nombreProducto']
values = (codigoEspecificoProducto,nombreProducto)
cursor.execute(query,values)
connStr.commit()
cursor.close()
connStr.close()
I think my problem is in how I'm defining the query, surely thats not the right way
Try this, you seem to have changed the library from pyodbc to mysql, it seems to expect %s instead of ?
import pymysql
import pandas as pd
connStr = pymysql.connect(host = 'xx.xxx.xx.xx', port = xxxx, user = 'xxxx', password = 'xxxxxxxxxxx')
df = pd.read_csv('GenericProducts.csv')
cursor = connStr.cursor()
query = "INSERT INTO [Productos]([ItemID],[Nombre]) values (%s,%s)"
for index,row in df.iterrows():
#cursor.execute("INSERT INTO dbo.Productos([ItemID],[Nombre]) values (%s,%s)", row['codigoEspecificoProducto'], row['nombreProducto'])
codigoEspecificoProducto = row['codigoEspecificoProducto']
nombreProducto = row['nombreProducto']
values = (codigoEspecificoProducto,nombreProducto)
cursor.execute(query,values)
connStr.commit()
cursor.close()
connStr.close()

Python sqlite3 parameterized drop table

I am having a problem with WTForms in Flask, I want to create a add_menu function which adds menu to the database. User can choose from SelectField "Appetizer", "Main Dish", or "Drinks" accordingly. So whenever user chooses the value from SelectField it adds to the corresponding table in a database. (I use MySQL). For some reason when I use menu_type = form.menu_type.data it gives me the following error
mysql_exceptions.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''main_dishes'(name,ingredients,price) VALUES('Salmon', 'duude,frv', '35')' at line 1")
It takes the right value, but I have this awkward '' signs infront of main_dishes string
My code looks as follows:
class MenuForm(Form):
menu_type = SelectField('Menu Type', [validators.DataRequired()], choices=[('appetizers','Appetizer'),('main_dishes','Main Dish'),('desserts','Dessert'),('drinks','Drinks')], coerce=str)
name = StringField('Name', [validators.Length(min=1, max=2000)])
ingredients = TextAreaField('Ingredients', [validators.Length(min=10)])
price = DecimalField('Price (Manat)', [validators.DataRequired()])
#app.route('/add_menu', methods=['GET','POST'])
#is_logged_in
def add_menu():
form = MenuForm(request.form)
if request.method == 'POST' and form.validate():
menu_type = form.menu_type.data # <---Here is the problem
name = form.name.data
ingredients = form.ingredients.data
price = form.price.data
#Create cursor
cur = mysql.connection.cursor()
#execute
cur.execute("INSERT INTO %s(name,ingredients,price) VALUES(%s, %s, %s)", (menu_type,name,ingredients,price))
#Commit to DB
mysql.connection.commit()
#CLose connection
cur.close()
flash('Menu is Added', 'success')
return redirect(url_for('dashboard'))
return render_template('add_menu.html', form=form)
The table name is substituted as a quoted string and the query executed as such.
You may want to build your query with the table name before binding parameterized values.
query = "INSERT INTO {}(name,ingredients,price) VALUES(%s, %s, %s)".format(menu_type)
cur.execute(query, (name,ingredients,price))
Isn't my coding typing wrong way? I need create an update button so user can edit the information by using Matlab. After update, the button need connect to mySQL server 5.6 and ODBC connector.
This is my code:
% --- Executes on button press in update.
function update_Callback(hObject, eventdata, handles)
% hObject handle to update (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
%Display dialog box to confirm save
choice = questdlg('Confirm update to database?', ...
'', ...
'Yes','No','Yes');
% Handle dialog box response
switch choice
case 'Yes'
%Set preferences with setdbprefs.
setdbprefs('DataReturnFormat', 'cellarray');
%Make connection to database.
conn = database('animal_cbir', '', '');
%Test if database connection is valid
testConnection = isconnection(conn);
disp(testConnection);
fileID = getappdata(0,'namevalue');
imageID = fileID;
name = get(handles.edit11,'String');
commonName = get(handles.edit1,'String');
scientificName = get(handles.edit2,'String');
class = get(handles.edit3,'String');
diet = get(handles.edit4,'String');
habitat = get(handles.edit5,'String');
lifeSpan = get(handles.edit6,'String');
size = get(handles.edit7,'String');
weight = get(handles.edit8,'String');
characteristic = get(handles.edit10,'String');
tablename = 'animal';
colnames ={'imageID','name','commonName','scientificName','class','diet','habitat','lifeSpan','size','weight','characteristic'};
data = {imageID,name,commonName,scientificName,class,diet,habitat,lifeSpan,size,weight,characteristic};
disp (data);
whereClause = sprintf(['where imageID = "%s"'],fileID);
update(conn,tablename,colnames,data,whereClause);
updateSuccess = helpdlg('Existing animal species successfully updated in database.');
commit(conn);
case 'No'
end
Error I am getting:
No method 'setInt' with matching signature found for class 'sun.jdbc.odbc.JdbcOdbcPreparedStatement'.
Hope that anyone can help me solve it.
