[sqlite] select null values in python
Using sqlite3 python and I have a problem running a query. My table has null values. Now if I do a 'select * from tablename' returns to me as the result: [(datetime.date (2012, 3, 22), buffer ptr read-write 0x03774B90, 0x03774B58 at size 0, None, None, None, None, None, None)] As you can see there are null values that in python are None type. If I want to run a query like select * from tablename where field1 = Null returns no results and even if I run select * from tablename where field1 = None None because there is not in Sqlite. You should use an adapter or something? -- Fabio Spadaro Try Sqlite Root a GUI Admin Tools for manage Sqlite Database: www.sqliteroot.com ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

http://www.sqlite.org/lang_altertable.html
says:
The execution time of the ALTER TABLE command is independent of the amount
of data in the table. The ALTER TABLE command runs as quickly on a table
with 10 million rows as it does on a table with 1 row.
Implicit in that statement is that ALTER TABLE does not modify/delete any
table data. If it did, the runtime would probably be O(N) or worse, not
O(1)
(as described above).

Ok I have been deceived by the anomaly that I found in my application. In
practice I have renamed the table (with alter table), I inserted a row and
then I inserted a new column (with alter table add column) and to my
surprise I saw the empty table. The problem is that my insert is not
successful and what you do not understand why try to make the insert taking the
old name of the table.
To recap:
Step 1: alter table pippo rename to fabio - ok
step 2: insert into fabio (field1) values ('1 ') - ko
OperationalError: no such table main.pippo
Step 3: alter table add column fabio field2 integer null - ok
result:
empty table
Question: Why does my insert referring to the old table?
use python sqlite vers. 2.5.9

http://www.sqlite.org/lang_createtable.html
If the default value of a column is CURRENT_TIME, CURRENT_DATE or
CURRENT_TIMESTAMP, then the value used in the new row is a text
representation of the current UTC date and/or time.
It won't be your local time.

What does SELECT sqlite_version() gives you in python with sqlite3
module?
[(u'3.5.9',)]
Well, CURRENT_DATE should work then, it was added in 3.1.0. Could you
show us an exact statement you are trying to execute and the exact
text of error you get?

After i just make insert: insert into timest (test) values ('2')
I see these values: '(u'2', datetime.datetime (2011,4, 22, 9, 37, 30) '
but the clock set up in my MS windows OS is set to different time.
In my system is set up with 11:35:07 while I am in the data 9:37:30

You retrieve the size of the BLOB field with sqlite3_column_bytes function, or with length() function in SQL. I'm not familiar with the term buffered file type. SQLite certainly doesn't store any such thing in the BLOB column. If you need to track some kind of metadata about your BLOB, store it yourself in additional columns in the same row. -- Igor Tandetnik ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users I use DB-API 2.0 interface for SQLite databases for python and seems that there is not a function equivalent or wrong? -- Fabio Spadaro www.fabiospadaro.com ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

It does not work, It always return data type text.
That is because your table has probably defined those columns as TEXT.
Consider the following --
sqlite CREATE TABLE t (a TEXT, b INTEGER);
sqlite INSERT INTO t VALUES ('foo', 5);
sqlite SELECT a, Typeof(a), b, Typeof(b) FROM t;
a Typeof(a) b Typeof(b)
