NameDescription bytecode A table-valued function that shows the bytecodes of a prepared statement. carray A table-valued function that allows a C-language array of integers, doubles, strings, or blobs to be used as a table in a query. closure Compute the transitive closure of a set. completion Suggests completions for partially-entered words during interactive SQL input. Used by the CLI to help implement tab-completion. csv A virtual table that represents a comma-separated-value or CSV file (RFC 4180) as a read-only table so that it can be used as part of a larger query. dbstat Provides information about the purpose and use of each page in a database file. Used in the implementation of the sqlite3_analyzer utility program. files_of_checkin Provides information about all files in a single check-in in the Fossil version control system. This virtual table is not part of the SQLite project but is included because it provides an example of how to use virtual tables and because it is used to help version control the SQLite sources. fsdir A table-valued function returning one row for each file in a selected file hierarchy of the host computer. Used by the CLI to help implement the .archive command. FTS3 A high-performance full-text search index. FTS5 A higher-performance full-text search index generate_series A table-valued function returning a sequence of integers, modeled after the table-valued function by the same name in PostgreSQL. json_each A table-valued function for decomposing a JSON string. json_tree A table-valued function for decomposing a JSON string. OsQuery Hundreds of virtual tables that publish various aspects of the host computer, such as the process table, user lists, active network connections, and so forth. OsQuery is a separate project, started by Facebook, hosted on GitHub, and intended for security analysis and intrusion detection. OsQuery is not a part of the SQLite project, but is included in this list because it demonstrates how the SQL language and the SQLite virtual table mechanism can be leveraged to provide elegant solutions to important real-world problems. pragma Built-in table-valued functions that return the results of PRAGMA statements for use within ordinary SQL queries. RTree An implementation of the Guttmann R*Tree spatial index idea. spellfix1 A virtual table that implements a spelling correction engine. sqlite_btreeinfo This experimental table-valued function provides information about a single B-tree in a database file, such as the depth, and estimated number of pages and number of entries, and so forth. sqlite_dbpage Key/value store for the raw database file content. The key is the page number and the value is binary page content. sqlite_memstat Provides SQL access to the sqlite3_status64() and sqlite3_db_status() interfaces. sqlite_stmt A table-valued function containing one row for each prepared statement associated with an open database connection. swarmvtab An experimental module providing on-demand read-only access to multiple tables spread across multiple databases, via a single virtual table abstraction. tables_used A table-valued function that shows the tables and indexes that are accessed by a prepared statement. tclvar Represents the global variables of a TCL Interpreter as an SQL table. Used as part of the SQLite test suite. templatevtab A template virtual table implementation useful as a starting point for developers who want to write their own virtual tables unionvtab An experimental module providing on-demand read-only access to multiple tables spread across multiple databases, via a single virtual table abstraction. vfsstat A table-valued function which, in combination with a co-packaged VFS shim provides information on the number of system calls performed by SQLite. vtablog A virtual table that prints diagnostic information on stdout when its key methods are invoked. Intended for interactive analysis and debugging of virtual table interfaces. wholenumber A virtual table returns all integers between 1 and 4294967295. zipfile Represent a ZIP Archive as an SQL table. Works for both reading and writing. Used by the CLI to implement the ability to read and write ZIP Archives.
