Step 1: Downloading an ODBC Driver for SQLite

  • Surf to the SQLite ODBC Driver Source page. Configuring the correct driver might be a little difficult, so it is recommended that you download both 32 and 64-bit drivers to migrate data from SQLite to SQL Server. 

Step 2: Installing the Driver

  • Next, you can choose to run either the 64-bit or 32-bit driver .exe file. You can make the choice based on the operating system you are using for moving data from SQLite to SQL Server.

Step 4: Creating a Linked Server in SQL Server

  • For this step, it is recommended that you leverage the following T-SQL snippet to create the linked server to your SQLite database. There aren’t any login accounts or any security context with this linked server.
USE [master]
GO
EXEC sp_addlinkedserver 
   @server = 'Mobile_Phone_DB_64', -- the name you give the server in SSMS 
   @srvproduct = '', -- Can be blank but not NULL
   @provider = 'MSDASQL', 
   @datasrc = 'Mobile_Phone_DB_64' -- the name of the system dsn connection you created
GO

Advantages of Using SQL Server Linked Servers to Connect to SQLite are:

  • Connection of other database instances on the same or remote server.
  • The distributed queries can be run on heterogeneous data sources across the organization.
  • It enables working with diverse data sources in the same manner.

Step 5: Selecting the Data from the Source and inserting it into SQL Server Database Table

  • This brings us to the last step of SQLite to SQL Server migration. Click on the linked server stem and expand it to the tables. You can then simply query the tables as follows:
Select *
from openquery(Mobile_Phone_DB_64 , 'select * from db_notes')
GO
  • You can make a table in your destination SQL Server with the following type of TSQL:
Select * into SQLite_Data -- This creates a table
from openquery(Mobile_Phone_DB_64 , 'select * from db_notes')
GO
  • Finally, you can modify the data types within your destination SQL Server database table by leveraging alter commands.

Limitations of ODBC Drivers:

  • ODBC drivers are slightly complicated to build and maintain. They are slow with large databases, and their servers are not standardized. 
  • Intricate SQLite schema elements like foreign keys, triggers, or user-defined functions may not be accurately translated by the ODBC driver. This may lead to inconsistencies in the target SQL databases. 
  • ODBC Driver does basic data transformations but lacks in dealing with complex data structures.

Migrating Data from SQLite to SQL Server: Best Practices to Follow

Here are a few best practices you can put into effect to get the most out of migrating data from SQLite to SQL Server:

  • The master database for migration from the SQLite database needs to be on a different disk (200 GB, RAID 5, SAS).
  • MDF files for the user’s databases need to be hosted on a separate disk (150 GB, SSD-, RAID 1/0).
  • You also need to make sure that the temporary databases are hosted on a separate disk (150 GB, SSD-, RAID 1/0).

When Should You Use SQL Server: Key Use Cases

SQL Server can primarily be leveraged as a relational database engine to manage and store data for multiple applications of ERP, CRM, and Automation. It is also widely utilized by a large number of teams across different project functions that need a database management solution. You can also use SQL Server as a backend for data staging, web apps, and SSIS/SSRS.

Before we wrap up, let’s cover some basics.

What is SQLite?

SQLite is an open-source Relational Database Management System (RDBMS). Most Relational Databases are based on the Client-Server model, which means that the Database typically runs on a server. However, SQLite is a Serverless Relational Database Management System, also referred to as an Embedded Database. SQLite Database operates from within the software that is accessing data. The Database can be accessed directly without the need for intermediation from a Host Server.

SQLite is self-contained, file-based, and is known for its portability, performance in low memory environments, and reliability. It is designed to work without a Database Administrator and is very easy to set up. The data transactions carried out in SQLite are ACID compliant [Atomicity, Consistency, Isolation, Durability]. SQLite, being an open-source tool, is available free of cost for all users. However, depending on the use case you can always pay for additional extensions.

Key Features of SQLite

Here are the key features of SQLite:

  • Cross-platform DBMS: You do not need a large range of different platforms like Mac OS, Windows, Unix, and Linux. You can even use it on a lot of embedded operating systems like Windows CE and Symbian.
  • Easy Storage: With SQLite, you are guaranteed an efficient way to store your user data.
  • Large Assortment of APIs: SQLite provides API for a large range of programming languages like Java, PHP, Python, Objective C, C#, and Visual Basic, to name a few.
  • Variable Length of Columns: The length of the columns is variable and not fixed. It facilitates you to allocate only the space a field might need. For instance, if you have a varchar(200) column, and you place a 10 characters length value on it, then SQLite would allocate only 20 characters’ space for that value as opposed to the complete space.
  • Flexible and Serverless: SQLite doesn’t need a different server system or process to operate and facilitates you to work on various databases in the same session at the same time.

When Should You Use SQLite: Key Use Cases

One of SQLite’s greatest advantages is that it can run on all platforms, including macOS, Windows, Linux, etc. SQLite is an RDBMS contained in a C library, hence the Applications written in any language can use SQLite as long as they can be connected to External Libraries written in C. Below are the appropriate uses for SQLite.

  • SQLite comes in handy for developing Embedded Software for Digital Devices like Televisions, Mobile Phones, Set-Top Boxes, Game Consoles, Cameras, etc.
  • Depending on your usage, you can leverage SQLite’s flexibility to work on multiple Databases in the same session simultaneously.
  • SQLite is used as a Temporary Dataset for Applications to get some processed data.
  • SQLite is a cross-platform DBMS, hence you can access it over all platforms including Windows, macOS, and more.
  • SQLite works well as a Database Engine for most websites, as it can manage low to medium-traffic HTTP requests.
  • Because it is simple to set up and use, it is used in Educational Institutions for learning and training purposes.

What is Microsoft SQL Server?

SQL Server is a relational database system provided by Microsoft. It can hold petabytes of data and have 100s of parallel running cores. It has a comprehensive querying layer that aids in business analysis and tightly integrates with reporting tools. Recent versions have spark support built-in; which means analyzing large amounts of data using Spark SQL without much additional setup needed.

It supports ANSI SQL, the standard SQL (structured query language) language. SQL Server comes with its implementation of the proprietary language called T-SQL (transact SQL). SQL server management studio (SSMS) is the main interface tool, consisting of a client and server. A client is an application for sending requests to the SQL Server installed on a given machine, whereas a server is capable of processing input data as requested.

SQL Server provides enterprise-grade security and support which makes it a favorite among organizations with strict compliance requirements. This post is about loading data from Google Analytics to SQL Server.

Key Features of SQL Server

Here are a few key features of SQL Server:

  • The Database Engine: This segment handles data storage, fast exchange processing, and data security.
  • The SQL Server: This assistance begins, pauses, stops, and continues the dataset process. 
  • The Server Agent: It plays out the job of the task scheduler. It tends to be set off by any occasion or according to request. 
  • The SQL Server Browser: This receives approaching queries and connects with the ideal SQL server instance. 
  • The SQL Server Full-Text Search: This permits the client to run a full-text search against Character information in SQL Tables.
