sqlparse

sqlparse is a non-validating SQL parser module. It provides support for parsing, splitting and formatting SQL statements.

Example Usage
Splitting SQL statements:

>>> import sqlparse
>>> sqlparse.split('select * from foo; select * from bar;')
[u'select * from foo; ', u'select * from bar;']

Formatting statemtents:

>>> sql = 'select * from foo where id in (select id from bar);'
>>> print sqlparse.format(sql, reindent=True, keyword_case='upper')
SELECT *
FROM foo
WHERE id IN
  (SELECT id
   FROM bar);

Parsing:

>>> sql = 'select * from someschema.mytable where id = 1'
>>> res = sqlparse.parse(sql)
>>> res
(<Statement 'select...' at 0x9ad08ec>,)
>>> stmt = res[0]
>>> unicode(stmt)  # converting it back to unicode
u'select * from someschema.mytable where id = 1'
>>> # This is how the internal representation looks like:
>>> stmt.tokens
