This program is not a visual shell for the sqlite command line tool, and doesnot require familiarity with SQL commands. It is a tool to be used by bothdevelopers and end users, and must remain as simple to use as possiblein order to achieve these goals.

Build products are named using one of the following templates: sqlite-product-version.zip sqlite-product-version.tar.gz sqlite-product-os-cpu-version.zip sqlite-product-date.zipTemplates (1) and (2) are used for source-code products. Template (1) isused for generic source-code products and templates (2) is used for source-codeproducts that are generally only useful on unix-like platforms. Template (3)is used for precompiled binaries products. Template (4) is used forunofficial pre-release "snapshots" of source code.The version is encoded so that filenames sort in order ofincreasing version number when viewed using "ls". For version 3.X.Y thefilename encoding is 3XXYY00. For branch version 3.X.Y.Z, the encoding is3XXYYZZ.The date in template (4) is of the form: YYYYMMDDHHMMFor convenient, script-driven extraction of the downloadablefile URLs and associated information, an HTML comment is embeddedin this page's source. Its first line (sans leading tag) reads:Download product data for scripts to readIts subsequent lines comprise a CSV table with this column header:PRODUCT,VERSION,RELATIVE-URL,SIZE-IN-BYTES,SHA3-HASHThe column header and following data lines have no leading space.The PRODUCT column is a constant value ("PRODUCT") for convenientregular expression matching. Other columns are self-explanatory.This format will remain stable except for possible new columnsappended to the right of older columns.Source Code RepositoriesThe SQLite source code is maintained in three geographically-dispersedself-synchronizingFossil repositories that areavailable for anonymous read-only access. Anyone canview the repository contents and download historical versionsof individual files or ZIP archives of historical check-ins.You can also clone the entire repository.

See the How To Compile SQLite page for additional informationon how to use the raw SQLite source code.Note that a recent version of Tclis required in order to build from the repository sources.The amalgamation source code files(the "sqlite3.c" and "sqlite3.h" files) build products and arenot contained in raw source code tree.

A standalone command-line shell program called sqlite3[39] is provided in SQLite's distribution. It can be used to create a database, define tables, insert and change rows, run queries and manage an SQLite database file. It also serves as an example for writing applications that use the SQLite library.

First, we need to create a new database and opena database connection to allow sqlite3 to work with it.Call sqlite3.connect() to create a connection tothe database tutorial.db in the current working directory,implicitly creating it if it does not exist:

We can verify that the new table has been created by queryingthe sqlite_master table built-in to SQLite,which should now contain an entry for the movie table definition(see The Schema Table for details).Execute that query by calling cur.execute(...),assign the result to res,and call res.fetchone() to fetch the resulting row:

Pass this flag value to the detect_types parameter ofconnect() to look up a converter function usingthe declared types for each column.The types are declared when the database table is created.sqlite3 will look up a converter function using the first word of thedeclared type as the converter dictionary key.For example:

Integer constant required by the DB-API 2.0, stating the level of threadsafety the sqlite3 module supports. This attribute is set based onthe default threading mode theunderlying SQLite library is compiled with. The SQLite threading modes are:

Deprecated since version 3.12, will be removed in version 3.14: This constant used to reflect the version number of the pysqlitepackage, a third-party library which used to upstream changes tosqlite3. Today, it carries no meaning or practical value.

Please consult the SQLite documentation about the possible values for the firstargument and the meaning of the second and third argument depending on the firstone. All necessary constants are available in the sqlite3 module.

The only argument passed to the callback is the statement (asstr) that is being executed. The return value of the callback isignored. Note that the backend does not only run statements passed to theCursor.execute() methods. Other sources include thetransaction management of thesqlite3 module and the execution of triggers defined in the currentdatabase.

The sqlite3 module is not built with loadable extension support bydefault, because some platforms (notably macOS) have SQLitelibraries which are compiled without this feature.To get loadable extension support,you must pass the --enable-loadable-sqlite-extensions optionto configure.

Controls the legacy transaction handling mode of sqlite3.If set to None, transactions are never implicitly opened.If set to one of "DEFERRED", "IMMEDIATE", or "EXCLUSIVE",corresponding to the underlying SQLite transaction behaviour,implicit transaction management is performed.

Control how a row fetched from this Cursor is represented.If None, a row is represented as a tuple.Can be set to the included sqlite3.Row;or a callable that accepts two arguments,a Cursor object and the tuple of row values,and returns a custom object representing an SQLite row.

This exception is not currently raised by the sqlite3 module,but may be raised by applications using sqlite3,for example if a user-defined function truncates data while inserting.Warning is a subclass of Exception.

Exception raised for sqlite3 API programming errors,for example supplying the wrong number of bindings to a query,or trying to operate on a closed Connection.ProgrammingError is a subclass of DatabaseError.

The type system of the sqlite3 module is extensible in two ways: you canstore additional Python types in an SQLite database viaobject adapters,and you can let the sqlite3 module convert SQLite types toPython types via converters.

By default, sqlite3 uses str to adapt SQLite valueswith the TEXT data type.This works well for UTF-8 encoded text, but it might fail for other encodingsand invalid UTF-8.You can use a custom text_factory to handle such cases.

sqlite3 offers multiple methods of controlling whether,when and how database transactions are opened and closed.Transaction control via the autocommit attribute is recommended,while Transaction control via the isolation_level attributeretains the pre-Python 3.12 behaviour.

sqlite3 ensures that a transaction is always open,so connect(), Connection.commit(), and Connection.rollback()will implicitly open a new transaction(immediately after closing the pending one, for the latter two).sqlite3 uses BEGIN DEFERRED statements when opening transactions.

His test app will create a database file, send some SQL commands to create a table, store some data in the table, and read it back and display on console. It will create the test.db file in the root directory of the project. You can run this example with java -cp .:sqlitejdbc-v056.jar Test.

To use the native version of sqlite-jdbc, user had to set a path to the native codes (dll, jnilib, so files, which are JNDI C programs) by using command-line arguments, e.g., -Djava.library.path=(path to the dll, jnilib, etc.), or -Dorg.sqlite.lib.path, etc. This process was error-prone and bothersome to tell every user to set these variables. Our SQLiteJDBC library completely does away these inconveniences.

The example code leads to a memory leak in Tomcat (after undeploying the webapp, the classloader still remains in memory) which will cause an outofmemory eventually. The way to solve it is to use the sqlite-jdbc-3.7.8.jar; it's a snapshot, so it doesn't appear for maven yet.

The SQLite project provides a simple command-line program namedsqlite3 (or sqlite3.exe on Windows)that allows the user to manually enter and execute SQLstatements against an SQLite database or against aZIP archive. This document provides a briefintroduction on how to use the sqlite3 program.

Start the sqlite3 program by typing "sqlite3" at thecommand prompt, optionally followedby the name of the file that holds the SQLite database(or ZIP archive). If the namedfile does not exist, a new database file with the given name will becreated automatically. If no database file is specified on thecommand-line, a temporary database is created and automatically deleted whenthe "sqlite3" program exits.

Make sure you type a semicolon at the end of each SQL command!The sqlite3 program looks for a semicolon to know when your SQL command iscomplete. If you omit the semicolon, sqlite3 will give you acontinuation prompt and wait for you to enter more text tocomplete the SQL command. This feature allows you toenter SQL commands that span multiple lines. For example:

Windows users can double-click on the sqlite3.exe icon to causethe command-line shell to pop-up a terminal window running SQLite. However,because double-clicking starts the sqlite3.exe without command-line arguments,no database file will have been specified, so SQLite will use a temporarydatabase that is deleted when the session exits.To use a persistent disk file as the database, enter the ".open" commandimmediately after the terminal window starts up:

Most of the time, sqlite3 just reads lines of input and passes themon to the SQLite library for execution.But input lines that begin with a dot (".")are intercepted and interpreted by the sqlite3 program itself.These "dot commands" are typically used to change the output formatof queries, or to execute certain prepackaged query statements.There were originally just a few dot commands, but over the yearsmany new features have accumulated so that today there are over 60. ff782bc1db
