Best ways to write a Pandas Dataframe on Fabric SQL Database

Hi all,

I am reading a REST API using Python and converting data in Pandas dataframe.

Now I am looking for the best fabric Item to store data and use SQL databases.

 

I do not want to use a lakehouse so I  think Warehouse is not the best option and I am trying preview SQL Database.

 

As there are no built in connectors I am thinking using SQL Alchemy / pyodbc , any recommendations?

 

I am migrating python code which works and stores data in an on premise SQL Server...and I am trying to migrate to a Fabric workspace with full SQL capabilities.

 

Which are best options to STORE dataframes as sql tables,,, and which are the best connection methods... entra id login, user/password,...

 

Regards

    Connect with Python Notebook

    Fabric Python Notebooks (preview) offer the ability to run T-SQL code with the T-SQL magic command. In the following steps, connect to a SQL database in Fabric using the %%tsql magic command:

    1. Create a notebook in your workspace with the language set to Python.

    2. In a cell, use the %%tsql magic command. The cell type automatically changes to T-SQL.

      In the following sample, replace <databasename> with the name of your SQL database in Fabric. The -type parameter should be SQLDatabase.

      PythonCopy
       
      %%tsql -artifact <databasename> -type SQLDatabase

      Then include your T-SQL command. For example, to run a query from a database named Contoso:

      PythonCopy
       
      %%tsql -artifact Contoso -type SQLDatabase
      SELECT * FROM SalesLT.Customer;
    3. You can also bind the results to a dataframe with the -bind argument:

      PythonCopy
       
      %%tsql -artifact Contoso -type SQLDatabase -bind df2

    For more possibilities to query your data with T-SQL inside Python Notebooks, see Run T-SQL code in Fabric Python notebooks. To see the full syntax, use the %tsql? command. This command displays the help information for the T-SQL magic command, including the available parameters and their descriptions.

    You can convert pandas dataframe to lakehouse/warehouse using python programming language. 

     

    SQL Database = Lakehouse = Fabric Warehouse = Power BI Direct Lake Semantic Model. They all are same. Simple and Sweet.

      can you be more specific we are having issues with data types in Spark dataframes, and this ir the reason to avoid using lakehouse or Warehouse...

       

      We have a program using pandas dataframes, how to save/store them in sql database in an fast/efficient way without having to convert to other types
