As it’s name says: it’s lite, and it doesn’t require a dedicated server. Three new objects are defined for specifying I/O procedures: sqlite3_vfs, sqlite3_file, and sqlite3_io_methods. Three new interfaces are used to create alternative OS interfaces: sqlite3_vfs_register(), sqlite3_vfs_unregister(), and sqlite3_vfs_find(). The Tcl procedures that SQLite calls to implement these programmer-defined functions need not be simple math functions such as shown above - they can be arbitrarily complex procedures. And, though the example above shows a procedure with a single argument, you can add as many additional arguments as you like. Download SQLiteStudio - Manage as many SQLite databases as you want and add new tables, triggers, columns and indexes with this practical and useful application ... trigger, procedure or statement ... SQLite has had to sacrifice other characteristics that some people find useful, such as high concurrency, fine-grained access control, a rich set of built-in functions, stored procedures, esoteric SQL language features, XML and/or Java extensions, tera- or peta-byte scalability, and so forth SQLite does not support stored procedures. See this: Appropriate Uses For SQLite, but this: Adding Stored Procedures to SQLite looks very interesting ;) [EDIT #1] Wow, Mehdi Gholam has answered it before ;) Sqlite- stored procedures/functions? [EDIT #2] New SQLite SQL statements for SQLite/PL Hello Devz, SQLite as a SQL Engine Database became a standard a few years ago already. As it’s name says: it’s lite, and it doesn’t require a dedicated server. Summary: this tutorial discusses SQLite trigger, which is a database object fired automatically when the data in a table is changed.. What is an SQLite trigger. An SQLite trigger is a named database object that is executed automatically when an INSERT, UPDATE or DELETE statement is issued against the associated table. SQLite is a software library that implements a SQL database engine. It is has a very clean architecture and a high level of code quality. Because of this, SQLite packs a wide range of features in a surprisingly small binary, 250 kB for version 2 and 450 kB for version 3 with all optional extensions compiled in. If SQLite supports store procedure, then we would like to expose it to the users. >You can store some procedures in triggers, if you want to have SQLite >trigger a task when some data is changed. >You can simply create a "Procedures" table like this: SQLite; Definition: It is an object-relational database management system (ORDBMS) that is compatible with various SQL features. It follows the transaction along with the ACID (Atomicity, Consistency, Isolation, and Durability) properties. It provides the complete support for foreign keys, View, Joins, Triggers, and Stored procedures. SQLite Viewer Tool is free to download to view SQLite files like .db, .db3, SQLite, SQLite3. Read, open and analyze SQLite DB created by browser cache and cookies, smartphone application and website data. An SQL procedure consists of a PROCEDURE clause that specifies the name of the procedure, an optional list of parameter definitions, and a single SQL statement. A procedure name cannot be the same as the name of an existing table. exec(conn,sqlquery) performs database operations on an SQLite database file by executing the SQL statement sqlquery for the SQLite connection conn using the MATLAB ® interface to SQLite. For example, use this syntax to create database tables in the SQLite database file. Users can use the SQLite Database Recovery to quickly retrieve the complete SQLite data recovery from the corrupt SQLite databases. This utility is compatible with all major Windows-based operating systems and also for the latest Win 10. However, to make the current version of SQLite compatible with the earlier version, SQLite allows the primary key column to contain NULL values. SQLite primary key and rowid table When you create a table without specifying the WITHOUT ROWID option, SQLite adds an implicit column called rowid that stores 64-bit signed integer.

SQLite COUNT aggregate function is used to count the number of rows in a database table. 2: SQLite MAX Function . SQLite MAX aggregate function allows us to select the highest (maximum) value for a certain column. 3: SQLite MIN Function. SQLite MIN aggregate function allows us to select the lowest (minimum) value for a certain column. 4: SQLite AVG Function Connecting to SQLite from SQL Server Management Studio using ODBC Driver for SQLite You can use the Microsoft SQL Server Management Studio to connect your SQLite data to an SQL Server instance. Linked Server is a tool of MS SQL Server that allows to execute distributed queries to refer tables stored on non-SQL Server datbase in a single query.
