SQLite ANALYZE StatementĪLTER TABLE table_name ADD COLUMN column_def. SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine. The SQLite project delivers a simple command-line tool named sqlite3 (or sqlite3.exe on Windows) that allows you to interact with the SQLite databases using SQL statements and commands. help - This is a single line commentĪll the SQLite statements start with any of the keywords like SELECT, INSERT, UPDATE, DELETE, ALTER, DROP, etc., and all the statements end with a semicolon ( ). Summary: in this tutorial, we will introduce you to the most commonly used SQLite commands of the sqlite3 command-line program. or tell it to read from that file: sqlite3 mydatabase.db '.read SQLTableTransfer'. As all the dot commands are available at SQLite prompt, hence while programming with SQLite, you will use the following SELECT statement with sqlitemaster table to list down all the tables created in your database. To execute commands from a file, you must redirect the input to that file: sqlite3 mydatabase.db < SQLTableTransfer. C-style comments can span multiple lines. The parameter you give to the sqlite3 program is the database file name. You can also use C-style comments, which begin with "/*" and extend up to and including the next "*/" character pair or until the end of input, whichever comes first. SQL comments begin with two consecutive "-" characters (ASCII 0x2d) and extend up to and including the next newline character (ASCII 0x0a) or until the end of input, whichever comes first. SQLite comments are extra notes, which you can add in your SQLite code to increase its readability and they can appear anywhere whitespace can occur, including inside expressions and in the middle of other SQL statements but they cannot be nested. the clauses GLOB and glob have the same meaning in SQLite statements. In SQLite, DDL (Data Definition Language) is used to create and modify database objects such as tables, indices, and views. Here are all commands and their description: SQLite Commands. The important point to be noted is that SQLite is case insensitive, i.e. SQLite Commands In SQLite, there are several dot commands which do not end with a semicolon( ). This chapter lists all the basic SQLite Syntax. Set Data and Listen for Changes, Use these references. SQLite is followed by unique set of rules and guidelines called Syntax.
