5. Secure storage in relational databases

Method 1: Add Parquet to CSV and Import into SQL Server

One of the most common approaches to import Parquet file into SQL Server is by converting them into CSV format first. The following method will help you to convert

Step 1: Convert Parquet to CSV:

You can use tools like Python (Pandas) or Apache Spark.

Using Python:

import pandas as pd

df = pd.read_parquet('file.parquet')

df.to_csv('file.csv', index=False)

Step 2: Import CSV into SQL Server:

1. Open SQL Server Management Studio (SSMS)
2. Right-click the database
3. Select Tasks > Import Data
4. Choose Flat File Source
5. Map columns and data types
6. Complete the import wizard

This method helps you understand how to load Parquet file in SQL Server, but it may not be efficient for large datasets.
