Thank you Simon and Igor for suggesting the cast() - that works without
me having to change anything! And of course I appreciate everyone's
replies as well.

Not sure about replacing the collation sequence - does not sound
easier than recreating the table.
You could just add a view:
sqlite> CREATE TABLE test_table (ID INTEGER PRIMARY KEY,

...> ExternalID INTEGER,

Yes, except for a small problem of updating all live databases with the
new column type. I don't think I can update the column type without
recreating the table, right? It's not hard, so if it comes down to
Hi Dennis,
Declaring the column as integer does not prevent you from storing strings:
SQLite version 3.6.0
Enter ".help" for instructions

...> INTEGER, Value INTEGER);

I haven't tried that, but I cannot declare it

Here's the table:
sqlite> .dump test_table
BEGIN TRANSACTION;
CREATE TABLE test_table (ID INTEGER PRIMARY KEY, ExternalID2 INTEGER,
ExternalID
INTEGER, Value );
INSERT INTO "test_table"
Funny enough, but it doesn't work on real data using v3.6.1...
Here's the table:
sqlite> .dump test_table
BEGIN TRANSACTION;
CREATE TABLE test_table (ID INTEGER PRIMARY KEY, ExternalID2 INTEGER,
ExternalID
INTEGER, Value );
INSERT INTO "test_table" VALUES(1007,1,37,'-5');
INSERT INTO
I've got 3.6.0 and it works fine here

That Data column could contain anything (int, double, string), it'll be
up to the application's logic to only get Data for
Could it be that since you're not defining a type for Data it assumes string?
Try creating the table with
id integer, externalid integer, data number (or numeric)

I'm using 3.3.5, I'll get the latest and see if works there or not in a
few minutes.

Yes, that works. Bad example on my part, sorry.
What doesn't work is this:
1|2|-7
2|2|-5
3|2|-20
4|2|-5
5|2|-2
SELECT max(Data) FROM (SELECT Data FROM test_table WHERE ExternalID=2);
This returns a -5, while I'm expecting a -2.
Thank

Hello all,
I've tried a few SQL statements, but can't seem to get it to work
properly, so I'd like to ask your help.
Suppose I have a table like this:
CREATE TABLE test_table (ID INTEGER PRIMARY KEY, ExternalID, Data);
And some contents:
1| 2| -7
2| 2| 5
3| 1| 0
4| 2| -20
5| 2| -5
6| 2| 1
7|
16 matches
