Question

I’ve found the SQL I searched to Update some fields but I got the error of the title:

UPDATE a
SET a.json = 'ex', a.last_save = 'ex', a.carte = 'ex'
FROM partie_l AS a
INNER JOIN carte AS b
ON a.start_carte = b.hash
WHERE b.json = 'ex' AND a.start_joueurs = 'ex' AND a.param = 'ex'

I’ve replaced my data with ex, else it would be too long.

Here is the structure of my tables.

CREATE TABLE "carte" ("hash" TEXT  NOT NULL PRIMARY KEY ,"json" TEXT NOT NULL ,"nb_jrs" INTEGER,"preview" BLOB, "creator" TEXT DEFAULT atoll, "name" TEXT, "tetra" BOOL)

CREATE TABLE "partie_l" ("id" INTEGER PRIMARY KEY  NOT NULL ,"json" TEXT,"create" DATETIME,"last_save" DATETIME,"start_carte" TEXT,"preview" BLOB,"param" TEXT,"start_joueurs" TEXT,"carte" TEXT, "name" TEXT)

Edit: Sqlite doesn’t support inner join

Answer 1

Try not using the table alias for the table to be updated.

UPDATE partie_l 
SET json = 'ex', 
    last_save = 'ex',
    carte = 'ex' 
FROM partie_l 
    INNER JOIN carte AS b 
    ON partie_l.start_carte = b.hash 
WHERE b.json = 'ex' AND partie_l.start_joueurs = 'ex' AND partie_l.param = 'ex' 

For SQLite try

UPDATE partie_l 
SET json = 'ex', 
    last_save = 'ex',
    carte = 'ex' 
WHERE partie_l.start_joueurs = 'ex' 
AND partie_l.param = 'ex' 
AND partie_l.start_carte IN (SELECT hash FROM carte WHERE json='ex')
