TO make it short, i've created 2 tables, user and movements: in the firs one there are the name, email and credit colons, in the second the colons from, to, import. So, i was triyng that way: BEGIN; INSERT INTO movements (from, to, import) VALUES ('mary', 'steve', 600); UPDATE users SET credit = credit - 600 WHERE name = 'mary'; UPDATE users SET credit = syntax error credit + 600 WHERE name = 'steve'; --here comes the problem!
