# based on https://stackoverflow.com/a/87531/5742651
# usage: sqlite3 .dump database_name.sqlite3 | perl sqlite2mysql.pl | mysql -u root -p $import_database_name
#
# ignore follow lines:
# BEGIN TRANSACTION 
# COMMIT 
#sqlite_sequence 
# CREATE UNIQUE INDEX
# PRAGMA foreign_keys=OFF
# "tablename/field" => `tablename/field`
# booleans 't' and 'f' => 1 and 0
# AUTOINCREMENT => AUTO_INCREMENT
# varchar => varchar(255)
# CREATE TABLE table... => DROP TABLE table; CREATE TABLE table...
# Merge insert sqls into multiple insert to speed up
# INSERT INTO table VALUES('val1');
# INSERT INTO table VALUES('val2'); => INSERT INTO table VALUES('val1'), ('val2'), ('val3');
# INSERT INTO table VALUES('val3');
