[sqlite, column 'name' is not unique. ?][-]

Not really ... never mind.

Baffled by the following situation.

- first query/result is the table that is used.

- Second query/result is generating the error.

$sQuery = "SELECT * FROM session_old;" {St} [0,0]
--- --- 0 (array dump), , GetTable2d:[5][5].
--- |--|               0|               1|   2|   3|           4|
[0] |St| name           | date           | x  | y  | crc        | 
[1] |St| tile_-1_-1.png | 20101115120514 | -1 | -1 | 1327511654 | 
[2] |St| tile_-1_0.png  | 20101115120514 | -1 | 0  | 2065193479 | 
[3] |St| tile_0_-1.png  | 20101115120514 | 0  | -1 | 3311147018 | 
[4] |St| tile_0_0.png   | 20101115120513 | 0  | 0  | 2328083747 | 
--- --- 0 [0,0]
$sQuery = "UPDATE session_old SET name = "tile_0_0.png" WHERE _rowid_ = 1" {St} [0,0]
!   SQLite.au3 Error
--> Function: _SQLite_Exec
--> Query:    UPDATE session_old SET name = "tile_0_0.png" WHERE _rowid_ = 1;
--> Error:    column name is not unique

"column name is not unique" ???

It only has one column with the name "name" ... and its also set to UNIQUE acourding to the table def.

- CREATE TABLE "session_old" (name TEXT UNIQUE NOT NULL, date NUMERIC NOT NULL, x INTEGER, y INTEGER, crc INTEGER)

I'm not seeing it ...

Try:

$sQuery = "UPDATE session_old SET name = 'tile_0_0.png' WHERE _rowid_ = 1" {St} [0,0]

I try to use " for autoit and ' for sqlite.

Fingers crossed ... nope, same error.

I try to use " for autoit and ' for sqlite.

[Checking SQLite docs ...]

If you want to use a keyword as a name, you need to quote it. There are three ways of quoting keywords in SQLite:

'keyword' A keyword in single quotes is a string literal.

"keyword" A keyword in double-quotes is an identifier.

...

... maybe.

Arrggg ...

New field data("tile_0_0.png") for column "name(UNIQUE)" is not UNIQUE.

Think its solved.

Quote below is by Roger Binns from the SQLite mailing list:

And just to blow your mind a little further, SQLite happily allows zero length table and columns names. This works.:

CREATE TABLE ""("" "");

INSERT INTO "" VALUES(3);

SELECT ""+"" FROM "";

But IMVHO, playing this kind of game is like bare feet on razor edges. Pick your choice :)
