![]() You cannot use it to rename a table, add or remove constraints, or change the data type of a column. Limited support for ALTER TABLE: The ALTER TABLE statement in SQLite has limited functionality.You can only use built-in functions or create custom functions using a programming language such as C. No support for user-defined functions: It does not support user-defined functions or stored procedures.All objects must be stored in a single namespace. ![]() No support for multiple schemas: It does not support multiple schemas within a single database file.No support for right outer joins: It does not support right outer joins using the standard INNER JOIN and OUTER JOIN syntax.Limited support for data types: The database has a limited set of data types, and it does not support some data types that are available in other database management systems, such as the date and time types.Limited alter table: You cannot rename a column, remove a column, or add a NOT NULL constraint to a column using the ALTER TABLE statement in SQLite.This can make it more challenging to manage the database and perform specific backups and restores. Single-file storage: It stores all of its data in a single file on a disk.Lack of some features: It does not support certain features that are available in other database management systems, such as views, stored procedures, and triggers.This can cause the database file to grow in size, especially if you have long-running transactions with many changes. This means that all changes within a transaction are stored in the rollback journal until the transaction is committed. Transactions: SQLite uses a rollback journal to implement transactions.This can lead to slower performance when multiple connections are trying to write to the database simultaneously. Concurrent writes: SQLite uses a file-based locking mechanism, which means that only one connection can write to the database at a time.SQLite has some limitations compared to other database management systems. What are the limitations of SQLite databases? Extensible: You can extend the database with custom functions and aggregates written in C or other programming languages.Replication: It supports replication using the same database file on multiple devices.Full-Text Search: It includes a full-text search engine that can be used to search for specific words or phrases in a database.Foreign Keys: You can define foreign key constraints to enforce relationships between tables.Views: You can create a virtual table that is a pre-defined SELECT statement.Triggers: You can specify a trigger to execute a set of SQL statements when an INSERT, UPDATE, or DELETE operation is performed on a table.Concurrency: It uses a file-based locking mechanism, which allows multiple connections to the database, but only one connection can write to the database at a time. ![]()
