# To use this script you will need to have installed package python-pyside which
# provides LGPL-licensed Python bindings for Qt.  You will also need the package
# libqt4-sql-sqlite for Qt sqlite3 support.
#
# Examples of installing pyside:
#
# ubuntu:
#
#	$ sudo apt-get install python-pyside.qtsql libqt4-sql-psql
#
#	Alternately, to use Python3 and/or pyside 2, one of the following:
#
#		$ sudo apt-get install python3-pyside.qtsql libqt4-sql-psql
#		$ sudo apt-get install python-pyside2.qtsql libqt5sql5-psql
#		$ sudo apt-get install python3-pyside2.qtsql libqt5sql5-psql
# fedora:
#
#	$ sudo yum install python-pyside
#
#	Alternately, to use Python3 and/or pyside 2, one of the following:
#		$ sudo yum install python3-pyside
#		$ pip install --user PySide2
#		$ pip3 install --user PySide2
#
# An example of using this script with Intel PT:
#
#	$ perf record -e intel_pt//u ls
#	$ perf script -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py pt_example branches calls
#	2017-07-31 14:26:07.326913 Creating database...
#	2017-07-31 14:26:07.538097 Writing records...
#	2017-07-31 14:26:09.889292 Adding indexes
#	2017-07-31 14:26:09.958746 Done
#
# To browse the database, sqlite3 can be used e.g.
#
#	$ sqlite3 pt_example
#	sqlite> .header on
#	sqlite> select * from samples_view where id < 10;
#	sqlite> .mode column
#	sqlite> select * from samples_view where id < 10;
#	sqlite> .tables
#	sqlite> .schema samples_view
#	sqlite> .quit
#
# An example of using the database is provided by the script
# exported-sql-viewer.py.  Refer to that script for details.
#
# The database structure is practically the same as created by the script
# export-to-postgresql.py. Refer to that script for details.  A notable
# difference is  the 'transaction' column of the 'samples' table which is
# renamed 'transaction_' in sqlite because 'transaction' is a reserved word.
