The ANALYZE command is enhanced to collect histogram data from all columns of every index and store that data in the sqlite_stat4 table.\u003cbr\u003e\u003cbr\u003eThe query planner will then use the histogram data to help it make better index choices. The downside of this compile-time option is that it violates the query planner stability guarantee making it more difficult to ensure consistent performance in mass-produced applications.\u003cbr\u003e\u003cbr\u003eSQLITE_ENABLE_STAT4 is an enhancement of SQLITE_ENABLE_STAT3. STAT3 only recorded histogram data for the left-most column of each index whereas the STAT4 enhancement records histogram data from all columns of each index.\u003cbr\u003e\u003cbr\u003eThe SQLITE_ENABLE_STAT3 compile-time option is a no-op and is ignored if the SQLITE_ENABLE_STAT4 compile-time option is used |\n| Allow URI Authority | sqlite_allow_uri_authority | URI filenames normally throws an error if the authority section is not either empty or \"localhost\".\u003cbr\u003e\u003cbr\u003eHowever, if SQLite is compiled with the SQLITE_ALLOW_URI_AUTHORITY compile-time option, then the URI is converted into a Uniform Naming Convention (UNC) filename and passed down to the underlying operating system that way |\n| App Armor | sqlite_app_armor | When defined, this C-preprocessor macro activates extra code that attempts to detect misuse of the SQLite API, such as passing in NULL pointers to required parameters or using objects after they have been destroyed. \u003cbr\u003e\u003cbr\u003eApp Armor is not available under `Windows`. |\n| Disable Load Extensions | sqlite_omit_load_extension | Loading of external extensions is enabled by default.\u003cbr\u003e\u003cbr\u003eTo disable extension loading add the build tag `sqlite_omit_load_extension`. |\n| Enable Serialization with `libsqlite3` | sqlite_serialize | Serialization and deserialization of a SQLite database is available by default, unless the build tag `libsqlite3` is set.\u003cbr\u003e\u003cbr\u003eTo enable this functionality even if `libsqlite3` is set, add the build tag `sqlite_serialize`. |\n| Foreign Keys | sqlite_foreign_keys | This macro determines whether enforcement of foreign key constraints is enabled or disabled by default for new database connections.\u003cbr\u003e\u003cbr\u003eEach database connection can always turn enforcement of foreign key constraints on and off and run-time using the foreign_keys pragma.\u003cbr\u003e\u003cbr\u003eEnforcement of foreign key constraints is normally off by default, but if this compile-time parameter is set to 1, enforcement of foreign key constraints will be on by default | \n| Full Auto Vacuum | sqlite_vacuum_full | Set the default auto vacuum to full |\n| Incremental Auto Vacuum | sqlite_vacuum_incr | Set the default auto vacuum to incremental |\n| Full Text Search Engine | sqlite_fts5 | When this option is defined in the amalgamation, versions 5 of the full-text search engine (fts5) is added to the build automatically |\n|  International Components for Unicode | sqlite_icu | This option causes the International Components for Unicode or \"ICU\" extension to SQLite to be added to the build |\n| Introspect PRAGMAS | sqlite_introspect | This option adds some extra PRAGMA statements. \u003cul\u003e\u003cli\u003ePRAGMA function_list\u003c/li\u003e\u003cli\u003ePRAGMA module_list\u003c/li\u003e\u003cli\u003ePRAGMA pragma_list\u003c/li\u003e\u003c/ul\u003e |\n| JSON SQL Functions | sqlite_json | When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically |\n| Math Functions | sqlite_math_functions | This compile-time option enables built-in scalar math functions. For more information see [Built-In Mathematical SQL Functions](https://www.sqlite.org/lang_mathfunc.html) |\n| OS Trace | sqlite_os_trace | This option enables OSTRACE() debug logging. This can be verbose and should not be used in production. |\n| Pre Update Hook | sqlite_preupdate_hook | Registers a callback function that is invoked prior to each INSERT, UPDATE, and DELETE operation on a database table. |\n| Secure Delete | sqlite_secure_delete | This compile-time option changes the default setting of the secure_delete pragma.\u003cbr\u003e\u003cbr\u003eWhen this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on.\u003cbr\u003e\u003cbr\u003eThe secure_delete setting causes deleted content to be overwritten with zeros.

See [Features](#features).\n\n## Usage\n\n### Create protected database\n\nTo create a database protected by user authentication, provide the following argument to the connection string `_auth`.\nThis will enable user authentication within the database. This option however requires two additional arguments:\n\n- `_auth_user`\n- `_auth_pass`\n\nWhen `_auth` is present in the connection string user authentication will be enabled and the provided user will be created\nas an `admin` user. After initial creation, the parameter `_auth` has no effect anymore and can be omitted from the connection string.\n\nExample connection strings:\n\nCreate an user authentication database with user `admin` and password `admin`:\n\n`file:test.s3db?_auth\u0026_auth_user=admin\u0026_auth_pass=admin`\n\nCreate an user authentication database with user `admin` and password `admin` and use `SHA1` for the password encoding:\n\n`file:test.s3db?_auth\u0026_auth_user=admin\u0026_auth_pass=admin\u0026_auth_crypt=sha1`\n\n### Password Encoding\n\nThe passwords within the user authentication module of SQLite are encoded with the SQLite function `sqlite_cryp`.\nThis function uses a ceasar-cypher which is quite insecure.\nThis library provides several additional password encoders which can be configured through the connection string.\n\nThe password cypher can be configured with the key `_auth_crypt`. And if the configured password encoder also requires an\nsalt this can be configured with `_auth_salt`.\n\n#### Available Encoders\n\n- SHA1\n- SSHA1 (Salted SHA1)\n- SHA256\n- SSHA256 (salted SHA256)\n- SHA384\n- SSHA384 (salted SHA384)\n- SHA512\n- SSHA512 (salted SHA512)\n\n### Restrictions\n\nOperations on the database regarding user management can only be preformed by an administrator user.\n\n### Support\n\nThe user authentication supports two kinds of users:\n\n- administrators\n- regular users\n\n### User Management\n\nUser management can be done by directly using the `*SQLiteConn` or by SQL.\n\n#### SQL\n\nThe following sql functions are available for user management:\n\n| Function | Arguments | Description |\n|----------|-----------|-------------|\n| `authenticate` | username `string`, password `string` | Will authenticate an user, this is done by the connection; and should not be used manually. |\n| `auth_user_add` | username `string`, password `string`, admin `int` | This function will add an user to the database.\u003cbr\u003eif the database is not protected by user authentication it will enable it. Argument `admin` is an integer identifying if the added user should be an administrator. Only Administrators can add administrators. |\n| `auth_user_change` | username `string`, password `string`, admin `int` | Function to modify an user. Users can change their own password, but only an administrator can change the administrator flag. |\n| `authUserDelete` | username `string` | Delete an user from the database. Can only be used by an administrator. The current logged in administrator cannot be deleted. This is to make sure their is always an administrator remaining. |\n\nThese functions will return an integer:\n\n- 0 (SQLITE_OK)\n- 23 (SQLITE_AUTH) Failed to perform due to authentication or insufficient privileges\n\n##### Examples\n\n```sql\n// Autheticate user\n// Create Admin User\nSELECT auth_user_add('admin2', 'admin2', 1);\n\n// Change password for user\nSELECT auth_user_change('user', 'userpassword', 0);\n\n// Delete user\nSELECT user_delete('user');\n```\n\n#### *SQLiteConn\n\nThe following functions are available for User authentication from the `*SQLiteConn`:\n\n| Function | Description |\n|----------|-------------|\n| `Authenticate(username, password string) error` | Authenticate user |\n| `AuthUserAdd(username, password string, admin bool) error` | Add user |\n| `AuthUserChange(username, password string, admin bool) error` | Modify user |\n| `AuthUserDelete(username string) error` | Delete user |\n\n### Attached database\n\nWhen using attached databases, SQLite will use the authentication from the `main` database for the attached database(s).\n\n# Extensions\n\nIf you want your own extension to be listed here, or you want to add a reference to an extension; please submit an Issue for this.\n\n## Spatialite\n\nSpatialite is available as an extension to SQLite, and can be used in combination with this repository.\nFor an example, see [shaxbee/go-spatialite](https://github.com/shaxbee/go-spatialite).\n\n## extension-functions.c from SQLite3 Contrib\n\nextension-functions.c is available as an extension to SQLite, and provides the following functions:\n\n- Math: acos, asin, atan, atn2, atan2, acosh, asinh, atanh, difference, degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp, log, log10, power, sign, sqrt, square, ceil, floor, pi.\n- String: replicate, charindex, leftstr, rightstr, ltrim, rtrim, trim, replace, reverse, proper, padl, padr, padc, strfilter.\n- Aggregate: stdev, variance, mode, median, lower_quartile, upper_quartile\n\nFor an example, see [dinedal/go-sqlite3-extension-functions](https://github.com/dinedal/go-sqlite3-extension-functions).\n\n# FAQ\n\n- Getting insert error while query is opened.\n\n    \u003e You can pass some arguments into the connection string, for example, a URI.\n    \u003e See: [#39](https://github.com/mattn/go-sqlite3/issues/39)\n\n- Do you want to cross compile? mingw on Linux or Mac?\n\n    \u003e See: [#106](https://github.com/mattn/go-sqlite3/issues/106)\n    \u003e See also: http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html\n\n- Want to get time.Time with current locale\n\n    Use `_loc=auto` in SQLite3 filename schema like `file:foo.db?_loc=auto`.\n\n- Can I use this in multiple routines concurrently?\n\n    Yes for readonly. But not for writable. See [#50](https://github.com/mattn/go-sqlite3/issues/50), [#51](https://github.com/mattn/go-sqlite3/issues/51), [#209](https://github.com/mattn/go-sqlite3/issues/209), [#274](https://github.com/mattn/go-sqlite3/issues/274).\n\n- Why I'm getting `no such table` error?\n\n    Why is it racy if I use a `sql.Open(\"sqlite3\", \":memory:\")` database?\n\n    Each connection to `\":memory:\"` opens a brand new in-memory sql database, so if\n    the stdlib's sql engine happens to open another connection and you've only\n    specified `\":memory:\"`, that connection will see a brand new database. A\n    workaround is to use `\"file::memory:?cache=shared\"` (or `\"file:foobar?mode=memory\u0026cache=shared\"`). Every\n    connection to this string will point to the same in-memory database.\n    \n    Note that if the last database connection in the pool closes, the in-memory database is deleted. Make sure the [max idle connection limit](https://golang.org/pkg/database/sql/#DB.SetMaxIdleConns) is \u003e 0, and the [connection lifetime](https://golang.org/pkg/database/sql/#DB.SetConnMaxLifetime) is infinite.\n    \n    For more information see:\n    * [#204](https://github.com/mattn/go-sqlite3/issues/204)\n    * [#511](https://github.com/mattn/go-sqlite3/issues/511)\n    * https://www.sqlite.org/sharedcache.html#shared_cache_and_in_memory_databases\n    * https://www.sqlite.org/inmemorydb.html#sharedmemdb\n\n- Reading from database with large amount of goroutines fails on OSX.\n\n    OS X limits OS-wide to not have more than 1000 files open simultaneously by default.\n\n    For more information, see [#289](https://github.com/mattn/go-sqlite3/issues/289)\n\n- Trying to execute a `.` (dot) command throws an error.\n\n    Error: `Error: near \".\": syntax error`\n    Dot command are part of SQLite3 CLI, not of this library.\n\n    You need to implement the feature or call the sqlite3 cli.\n\n    More information see [#305](https://github.com/mattn/go-sqlite3/issues/305).\n\n- Error: `database is locked`\n\n    When you get a database is locked, please use the following options.\n\n    Add to DSN: `cache=shared`\n\n    Example:\n    ```go\n    db, err := sql.Open(\"sqlite3\", \"file:locked.sqlite?cache=shared\")\n    ```\n\n    Next, please set the database connections of the SQL package to 1:\n    \n    ```go\n    db.SetMaxOpenConns(1)\n    ```\n\n    For more information, see [#209](https://github.com/mattn/go-sqlite3/issues/209).\n\n## Contributors\n\n### Code Contributors\n\nThis project exists thanks to all the people who [[contribute](CONTRIBUTING.md)].\n\u003ca href=\"https://github.com/mattn/go-sqlite3/graphs/contributors\"\u003e\u003cimg src=\"https://opencollective.com/mattn-go-sqlite3/contributors.svg?width=890\u0026button=false\" /\u003e\u003c/a\u003e\n\n### Financial Contributors\n\nBecome a financial contributor and help us sustain our community.
