I have data that I am sending to my NodeJs server that is in the standard SQL format with the default SQL column names etc.
I want to take these raw entities and reinsert them into the db. It seems like I can't insert them straight up without converting them into entities, or preparing a raw SQL statement.
I want to turn these values into TypeORM entities automatically without having to write transform functions.
Is there a good way to accomplish this in TypeORM?

I have a web application where users can upload CSVs. I use Python Pandas to actually do the upload. I have to give the users the ability to change the database table's column's types such as from strings to datetimes. Is there a way to do this in Sqlalchemy? I'm working with reflected tables, and so I have Table objects with all their columns but I have a feeling that Sqlalchemy does not have this capability and that I will have to execute raw SQL to do this.
I am using the WPForms Pro version that stored the entries into a database. I found out that WPForms stored the data into my database as JSON into the fields column of wp_entries table.
I need to further process this data into reports and I would love this data to be available as standard SQL table.
Does anyone know how to convert this JSON code into a SQL output using SQL code? I have tried JSON_TABLE function but I'm a bit unfamiliar with that logic.
Backend is MySQL / MariaDB.
My JSON data looks something like this:
{"5":{"name":"Locate cost","value":"0.90","id":5,"type":"number"},"3":{"name":"Ticker","value":"IDAI","id":3,"type":"text"}
Thanks!
I am in a situation where I need to convert my dynamically generated SQL Server query to Mongo DB query. Is there any tool/plugin/nuget package available that takes sql server query as input and outputs mongodb query(just like what is done in "www.querymongo.com")?
No
I would add than you don't send interpreted language (sql) than you can adapt according to the database server, but you use a proprietary API :
http://docs.mongodb.org/ecosystem/tutorial/use-linq-queries-with-csharp-driver/
Have created a JS for creating the Mongo queries dynamically, based on the operators selected.
I am making csv file by sql2excell component for joomla. It calls the data by SQL queries, so I retrieve all the information through SQL queries. The problem is some that fields have extra information which I don't want to display to the end user.
For example, the fields show the data below when I retrieve by a query:
a:3:{s:4:"city";s:3:"000";s:3:"ext";s:3:"000";s:3:"tel";s:4:"0000";}
I only want the values that are in quotes, like this: 0000000000
Is there any way I can get this by an SQL query?
No.
These values are serialized and MySQL doesn't have functions to deserialize them. You have to make a bridge between MySQL and sql2excel which would decode it, but Im not familiar with this tool so can't be of much help.
I have my data in the mysql database but i want to update my database tables without affecting the old data.
and i need the functionality that i can fetch the old data as well as new updated data as and when required in the software according to the date
Here's one way to do what you describe:
Add a datetime column—let's say INSERTED_DT—to your database.
Populate INSERTED_DT with the current datetime on insert and/or on update. Most DBMSs have some facility to make it easy to do this kind of thing.
Write database queries with parameters to extract relevant sections of your database based on INSERTED_DT.
