The SQLite library is designed to be very easy to use from a Tcl or Tcl/Tk script. SQLite began as a Tcl extension and the primary test suite for SQLite is written in TCL. SQLite can be used with any programming language, but its connections to TCL run deep.

This document gives an overview of the Tcl programming interface for SQLite.

sqlite3 db1 ./testdb

db1 eval {CREATE TABLE t1(a int, b text)}
