Hello all i am trying my best to reset the auto-increment on DB browser but coming up with multiple santex errors,


error log, ALTER TABLE User AUTOINCREMENT -- Result: near "AUTOINCREMENT": syntax error -- EXECUTING ALL IN 'SQL 1'


SET @num :=0;

UPDATE User SET UserID = @num := (@num+1);


error log SET -- Result: near "SET": syntax error

You cannot use ALTER TABLE for that. The autoincrement counter is stored in a separate table named "sqlite_sequence". You can modify the value there:

UPDATE sqlite_sequence SET seq=1 WHERE name="<table>"

That would be:

UPDATE sqlite_sequence SET seq=1 WHERE name='<table>'

In SQL double-quotes are for identifiers and single-quotes are for strings.

Yepp, sorry about that. Didn't realize that

is a string in this case, not an identifier ;)
