20# To use this script you will need to have installed package python-pyside which
21# provides LGPL-licensed Python bindings for Qt. You will also need the package
22# libqt4-sql-sqlite for Qt sqlite3 support.
23#
24# Examples of installing pyside:
25#
26# ubuntu:
27#
28# $ sudo apt-get install python-pyside.qtsql libqt4-sql-psql
29#
30# Alternately, to use Python3 and/or pyside 2, one of the following:
31#
32# $ sudo apt-get install python3-pyside.qtsql libqt4-sql-psql
33# $ sudo apt-get install python-pyside2.qtsql libqt5sql5-psql
34# $ sudo apt-get install python3-pyside2.qtsql libqt5sql5-psql
35# fedora:
36#
37# $ sudo yum install python-pyside
38#
39# Alternately, to use Python3 and/or pyside 2, one of the following:
40# $ sudo yum install python3-pyside
41# $ pip install --user PySide2
42# $ pip3 install --user PySide2
43#
44# An example of using this script with Intel PT:
45#
46# $ perf record -e intel_pt//u ls
47# $ perf script -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py pt_example branches calls
48# 2017-07-31 14:26:07.326913 Creating database...
49# 2017-07-31 14:26:07.538097 Writing records...
50# 2017-07-31 14:26:09.889292 Adding indexes
51# 2017-07-31 14:26:09.958746 Done
52#
53# To browse the database, sqlite3 can be used e.g.
54#
55# $ sqlite3 pt_example
56# sqlite> .header on
57# sqlite> select * from samples_view where id < 10;
58# sqlite> .mode column
59# sqlite> select * from samples_view where id < 10;
60# sqlite> .tables
61# sqlite> .schema samples_view
62# sqlite> .quit
63#
64# An example of using the database is provided by the script
65# exported-sql-viewer.py. Refer to that script for details.
66#
67# The database structure is practically the same as created by the script
68# export-to-postgresql.py. Refer to that script for details. A notable
69# difference is the 'transaction' column of the 'samples' table which is
70# renamed 'transaction_' in sqlite because 'transaction' is a reserved word.
