function to update tables of different sizes

David Shapero :

So I wanted to create a function, that take a dictionary and update the database based on the key/values pairs on that dictionary.

My main problem is that I have tables of different row sizes, so my dictionaries will have also different sized I am not sure how to handle that. for example

table 1: date | id | startDate | firmwareVersion | location | lastUpdate|

list 1: {date :1583171545,id : 22, startDate 1582131612, firmwareVersion: 1.7, location: "A", lastUpdate: 1583051569, },{date :1583171545,id : 32, startDate 1582131452, firmwareVersion: 1.6, location: "B", lastUpdate: 1583051569, }

table 2: date | error| list 2: {date: 1583171545, error: "whateverError" }

I am not speaking about the size of data in each row but the number of rows is different.

Here is my function, how can I change it to handle updating both table 1 or 2 regardless of which one is passed to it.

def my_function(table, table_name):
    cursor.execute(f"INSERT INTO {table_name} () VALUES ()")

my_function(sensorstable, "sensorstable")

, also passe the name of the table, but ideally I wish I could use the variable name as the table name. for example:

if my dictionary is saved into a variable deviceList, I would want to use deviceList as the database name.

GHOST :

you can do something simple like this

{date :1583171545,id : 22, startDate 1582131612, firmwareVersion: 1.7, location: "A", lastUpdate: 1583051569, },{date :1583171545,id : 32, startDate 1582131452, firmwareVersion: 1.6, location: "B", lastUpdate: 1583051569, }


def update_table_last_valid_value(table, table_name):
    column_values = []
    if table:
        column_keys = list(table.keys())
        column_keys = ", ".join(column_keys)
        for key, value in table.items():
            column_values.append(value)
        cursor.execute(f"INSERT INTO {table_name} ({column_keys}) VALUES {tuple(column_values)};")
            cursor.close()
            return result

of course this is assuming you have just one row as it seems like it's the case, otherwise you might wanna tweak it a little bit
