How different is SQLite from SQL Server?

Is SQLite a SQL Server?

SQLite is a self-contained, high-reliability, embedded, full-featured, public-domain, SQL database engine. It's among the most well-known and widely used relational database engines in the world.

How SQLite is different from other database?

Is self-contained, it requires minimal support from the operating system or external library. This makes SQLite usable in any environment especially in embedded devices like iPhones, Android phones, game consoles, handheld media players. Does not use any configuration files. Is ACID-compliant.

Does SQLite have the same syntax as SQL?

SQLite understands most of the standard SQL language. But it does omit some features while at the same time adding a few features of its own. This document attempts to describe precisely what parts of the SQL language SQLite does and does not support. A list of SQL keywords is also provided.

Should I learn SQL or SQLite?

I'd recommend learning standard SQL before SQLite's version of SQL. SQLite allows a lot of things (such as automatic type conversions and incomplete GROUP BY clauses) that a lot of databases don't allow. Also, everything in SQLite is stored as a string but that's not the case for other versions of SQL.
