Inserting row from database to another



I am trying to insert a row from a database server to another database server in a different environment using pymysql


prod_conn = pymysql.connect(
prod_common_db_endpoint,
prod_user,
prod_password,
prod_common_table_name)

prod_cursor = prod_conn.cursor()


prod_ConnectFirm_table = prod_cursor.execute("select * from Common.ConnectFirm where FirmId = " + prod_source_firm + ";")
for row in prod_ConnectFirm_table:
ConnectFirmId = int(row[1])
ConnectFirmName = (row[2])
FirmId = int(row[3])
isDeleted = (row[4])
tags = (row[5])
createdDate = (row[6])
createdBy = int(row[7])
editedDate = (row[8])
editedBy = int(row[9])


conn = pymysql.connect(target_common_db_endpoint, user, password, common_schema_name)

cursor = conn.cursor()

cursor.execute("INSERT INTO Common.ConnectFirm(ConnectFirmId, ConnectFirmName, editedDate) VALUES(" + ConnectFirmId + ", " + ConnectFirmName + ", " + editedDate + ", ")")
conn.commit()
print("error inserting")



it fails giving me this error


Traceback (most recent call last):
File "sql_test_3_d.py", line 109, in <module>
for row in prod_orionConnectFirm_table:
TypeError: 'int' object is not iterable





Why are you connecting to db in every step of loop? Can you change the indentation?

Dont convert your values to tuple. It will throw error while concatenating with other string objects

@mad_ I am connecting to two databse servers and I am trying to have connection to both of them so I can select from one database and insert to the other one. I am not sure if I'm doing it the right way!

prod_ConnectFirm_table will contain execution status which is an integer value which you can't over.So after executing the query as :


prod_ConnectFirm_table = prod_cursor.execute("select * from Common.ConnectFirm where FirmId = " + prod_source_firm + ";")



you need to fetch data from cursor :


data = prod_cursor.fetchall()



"data" will contain the query result in form of tuple which you parse over.





I believe it is more of a comment rather than an answer.

@mad_ it would have been best if you would have edited my answer or pointed out the mistake, i would love to improve the answer and probably would have kept few things in mind while answering next time, Thanks

@dilkash your suggestion eliminated the error of TypeError: 'int' object is not iterable, but I get a different one this time Traceback (most recent call last): File "sql_test_3_d.py", line 139, in <module> " + editedBy + ")") TypeError: must be str, not int

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12...

Creating a leaderboard in HTML/JS

Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
