[sqlite] sqlite3 problems on both 32 and 64 architectures
Hallo, assertions like this (btree.c, line 1043) are bad: assert( sizeof(ptr)==sizeof(char*) ); The problem better is described here: http://bugs.kde.org/show_bug.cgi?id=92563 Reporters say that even for intel P4, sizeof pointers is 8, not 4 there. Any plans for fixing these bugs in official sqlite release? -- regards / pozdrawiam, Jaroslaw Staniek / OpenOffice Polska Developers wanted!

BTW, I have some comments on your database sample: 1. the bug was triggered by the definition of foreign keys. you use the syntax: create table x( device_id integer references Device it would be more appropriate to do this: create table x( device_id integer references Device(Device_ID) this gives more complete information for the schema. also, I noticed that you use mixed semantics in your column typing: Integer Integer(5) Varchar varchar(32) If you plan to use the strong typing of SqliteExplorer, you should be more consistent, and use : integer varchar(32) what is the meaning of varchar without a size ? did you mean a text blob ? if so, use the definition CLOB, which will give your column text affinity, which is something you want in order to avoid unnecessary attempts to convert to numeric values. true, the "varchar" definition also gives you TEXT affinity, but, since there IS a "preferred" type to declare text blobs, (CLOB), why not use it ? Sqlite3Explorer will recognize it, and give you a multi-line editor to edit/display this field.
[sqlite] column def vs. constraint at end of create table stmt
hi- I am working on making my program for viewing sql statement results and changing table structure a little nicer. the reason the question came about below is I thought I'd like to add capability to have more than one field be the primary key and also would like to add the constraint unique to work the same. if I have a column def statement for every field and specify unique and primary constraints in each column def, what is the reason the constraint that goes on the very end of the create table would be needed [, constraint]* column-def ::= name [type] [[CONSTRAINT name] column-constraint]* sql-command ::= CREATE [TEMP | TEMPORARY] TABLE table-name ( column-def [, column-def]* [, constraint]* ) thank you very much, jim

Thanks for your reply, however, wcstombs uses the default code page rather that UTF8, which is where I was going wrong with using it originally.

The code to parse filenames is not UTF8 aware, and so will cause problems when splitting a filename into directory and filename components if the string is a UTF8 string. The offending function appears to be sqlitepager_open in pager.c, which steps backwards through the path name a character at a time looking the directory seperator character, which will obviously be tripped up by a multi-byte character. You should probably avoid using UTF8 for filenames, or raise a bug if you really need UTF8 filenames. > >Thanks, > >Liz. > Christian -- /"\ \ /ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL X - AGAINST MS ATTACHMENTS / \

There is none. Did you actually try INSERT ... SELECT and found the
performance inadequate?
Use ATTACH to attach the file database to your in-memory
database. Then do a
INSERT INTO file.table1 SELECT * FROM main.table1;
for each table.
I try to do this in a little test in C#; here is my code :
SQLiteConnection Conn = new SQLiteConnection();
Conn.ConnectionString = "Data
Source=:memory:;New=True;Compress=True;Synchronous=Off";
Conn.Open();
SQLiteCommand Cmd = new SQLiteCommand();
Cmd = Conn.CreateCommand();
Cmd.CommandText = "CREATE table mp3Lst (mp3Id integer
primary key, mp3File varchar(100))";
Cmd.ExecuteNonQuery();
SQLiteTransaction Transact;
ArrayList alMp3Lst = new ArrayList();
alMp3Lst.Add("1.mp3");
alMp3Lst.Add("2.mp3");
alMp3Lst.Add("3mp3");
alMp3Lst.Add("4.mp3");
alMp3Lst.Add("5.mp3");
Transact = (SQLiteTransaction) Conn.BeginTransaction();
foreach (string mp3File in alMp3Lst)
{
Cmd.CommandText = String.Format("INSERT INTO mp3Lst
(mp3File) VALUES ('{0}')", mp3File);
Cmd.ExecuteNonQuery();
}
Transact.Commit();
Cmd.CommandText = "ATTACH DATABASE database AS main";
Cmd.ExecuteNonQuery();
Cmd.CommandText = "INSERT INTO database.mp3Lst SELECT * FROM
main.mp3Lst";
Cmd.ExecuteNonQuery();
As you can see, it's quite simple :).
I have an error after doing the ATTACH DATABASE, which is :
SQL logic error or missing database: database main is already in use
=> I'm new to sqlite so perharps I do a mistake in the ATTACH DATABASE
method ?
