That's SQLite's lower() function. If you'd like to use Python's lower()
function, you should call lower() on the string and use
column.like(mystring.lower()). But that won't do case-insensitive comparison
since you need to call lower() on the database column in the statement.
So you really need to first get this statement to work with pysqlite, to
figure out what collation issues may exist with sqlite3 or encoding issues
with pysqlite:
import sqlite3
connection = sqlite3.connect(/path/to/your/db)
cursor = connection.cursor()
cursor.execute(SELECT * FROM patients WHERE lower(lastname) LIKE lower(?),
['Ivanov'])
print cursor.fetchall()
SQLAlchemy doesn't look at the contents of your string at all with pysqlite,
its a pass through.

Hello!
I have gtk application with sqlite db, contain russian words.
My model
code
class Patient(Base):
lastname = Column(Unicode)
/code
Search operation
code
patients = self.session.query(Patient)
lastname = unicode(self.lastname_entry.get_text())
if lastname:
patients = patients.filter(Patient.lastname.like(u%%%s%% %
lastname))
/code
It perfectly work if i search as 'Ivanov', but didn't return results
if i search 'ivanov'. Note, i search russian words, not english.
In SQLite manager (firefox plugin) search query
code
SELECT * FROM patients WHERE lastname LIKE %ivanov%
/code
If i query db and look at value:
code
In [28]: p.lastname
Out[28]: u'\u0413\u0430\u043f\u0447\u0443\u043a'
/code
and than check it in query, generated by SQLAlchemy
code
In [29]: patients.filter(Patient.lastname.ilike(u%%%s%% %
l.decode('utf-8'))).count()
2011-01-20 21:20:30,950 INFO sqlalchemy.engine.base.Engine.0x...1250
SELECT count(1) AS count_1
FROM patients
WHERE lower(patients.lastname) LIKE lower(?)
2011-01-20 21:20:30,950 INFO sqlalchemy.engine.base.Engine.0x...1250
(u'%\u0433\u0430\u043f\u0447\u0443\u043a%',)
Out[29]: 0
/code
It is looked like lower function in SQLAlchemy didn't understood
cyrillic ...
Thanks!
