The sqlite3_open_v2 () interface works like sqlite3_open () except that it accepts two additional parameters for additional control over the new database connection.

- Database Connection Handle
typedef struct sqlite3 sqlite3; Each open SQLite database is represented by a pointer to an instance of the opaque structure named "sqlite3". It is useful to think of an sqlite3 pointer as an object. The sqlite3_open (), sqlite3_open16 (), and sqlite3_open_v2 () interfaces are its constructors, and sqlite3_close () and sqlite3_close_v2 () are its destructors. There are many other interfaces ...

The following two objects and eight methods comprise the essentialelements of the SQLite interface: 1. sqlite3 →The database connection object. Created bysqlite3_open() and destroyed by sqlite3_close(). 2. sqlite3_stmt →The prepared statement object. Created bysqlite3_prepare() and destroyed by sqlite3_finalize(). 3. sqlite3_open() →Open a connecti...
SQLite has more than 225 APIs. However, most of the APIs are optional and very specialized and can be ignored by beginners. The core API is small, simple, and easy to learn. This article summarizes the core API. A separate document, The SQLite C/C++ Interface, provides detailed specifications for all C/C++ APIs for SQLite. Once the reader understan...
The principal task of an SQL database engine is to evaluate SQL statements of SQL. To accomplish this, the developer needs two objects: 1. The database connectionobject: sqlite3 2. The prepared statementobject: sqlite3_stmt Strictly speaking, the prepared statement object is not required since the convenience wrapper interfaces, sqlite3_exec or sql...
An application will typically use sqlite3_open() to create a single database connection during initialization. Note that sqlite3_open() can be used to either open existing database files or to create and open new database files. While many applications use only a single database connection, there is no reason why an application cannot call sqlite3_...
The sqlite3_exec() interface is a convenience wrapper that carries out all four of the above steps with a single function call. A callback function passed into sqlite3_exec() is used to process each row of the result set. The sqlite3_get_table() is another convenience wrapper that does all four of the above steps. The sqlite3_get_table() interface ...
In prior discussion, it was assumed that each SQL statement is prepared once, evaluated, then destroyed. However, SQLite allows the same prepared statementto be evaluated multiple times. This is accomplished using the following routines: 1. sqlite3_reset() 2. sqlite3_bind() After a prepared statement has been evaluated by one or more calls to sqlit...
The default configuration for SQLite works great for most applications. But sometimes developers want to tweak the setup to try to squeeze out a little more performance, or take advantage of some obscure feature. The sqlite3_config() interface is used to make global, process-wide configuration changes for SQLite. The sqlite3_config() interface must...
SQLite includes interfaces that can be used to extend its functionality. Such routines include: 1. sqlite3_create_collation() 2. sqlite3_create_function() 3. sqlite3_create_module() 4. sqlite3_vfs_register() The sqlite3_create_collation() interface is used to create new collating sequences for sorting text. The sqlite3_create_module() interface is ...
This article only mentions the most important and most commonly used SQLite interfaces. The SQLite library includes many other APIs implementing useful features that are not described here. A complete list of functions that form the SQLite application programming interface is found at the C/C++ Interface Specification. Refer to that document for co...
Jul 6, 2014 · DB Browser for SQLite DB Browser for SQLite (DB4S) is a high quality, visual, open source tool designed for people who want to create, search, and edit SQLite or SQLCipher database files. DB4S gives a familiar spreadsheet-like interface on the database in addition to providing a full SQL query facility.
The fourth parameter to sqlite3_open_v2 () is the name of the sqlite3_vfs object that defines the operating system interface that the new database connection should use. If the fourth parameter is a NULL pointer then the default sqlite3_vfs object is used.
1 day ago · sqlite3 — DB-API 2.0 interface for SQLite databases ¶ Source code: Lib/sqlite3/ SQLite is a C library that provides a lightweight disk-based database that doesn’t require a separate server process and allows accessing the database using a nonstandard variant of the SQL query language. Some applications can use SQLite for internal data storage. It’s also possible to prototype an ...

SQLITE3_OPEN_READWRITE: Open the database for reading and writing. SQLITE3_OPEN_CREATE: Create the database if it does not exist. encryptionKey An optional encryption key used when encrypting and decrypting an SQLite database. If the SQLite encryption module is not installed, this parameter will have no effect.
