SQLite is a small C library that implements a self-contained, embeddable, zero-configuration SQL database engine. The SQLite distribution comes with a standalone command-line access program (sqlite) that can be used to administer an SQLite database and which serves as an example of how to use the SQLite library. Create A New Database: пїЅ At a shell or DOS prompt, enter: "sqlite3 test.db". This will create a new database named "test.db". (You can use a different name if you like.) пїЅ Enter SQL commands at the prompt to create and populate the new database. Write Programs That Use SQLite Below is a simple TCL program that demonstrates how to use the TCL interface to SQLite. The program executes the SQL statements given as the second argument on the database defined by the first argument. The commands to watch for are the sqlite3 command on line 7 which opens an SQLite database and creates a new TCL command named "db" to access that database, the invocation of the db command on line 8 to execute SQL commands against the database, and the closing of the database connection on the last line of the script. #!/usr/bin/tclsh if {$argc!=2} { puts stderr "Usage: %s DATABASE SQL-STATEMENT" exit 1 } load /usr/lib/tclsqlite3.so Sqlite3 sqlite3 db [lindex $argv 0] db eval [lindex $argv 1] x { foreach v $x(*) { puts "$v = $x($v)" } puts "" } db close Here are some key features of "SQLite":
