I need to generate a couple of dozen statements reseting my sequences
so that they're next values are greater than the biggest existing ids.
The problem is, I can't even form a statement to update one sequence.
This is what I tried:
CREATE OR REPLACE FUNCTION init_sequences() RETURNS void AS
$BODY$
DECLARE
next_id_table1 INTEGER;
BEGIN
SELECT INTO next_id_table1 MAX(id)+1 FROM table1;
ALTER SEQUENCE pk_table1 RESTART next_id_table1;
END;
$BODY$
LANGUAGE 'plpgsql';
The problem seems to be the ALTER statement:
ERROR: syntax error at or near "$1" at character 36
QUERY: ALTER SEQUENCE pk_table1 RESTART $1
CONTEXT: SQL statement in PL/PgSQL function "init_sequences" near line 5
If I change the ALTER statement like this
ALTER SEQUENCE pk_table1 RESTART 200;
it works. But is obviously not what I wanted.
Is there a way to get the ALTER SEQUENCE statement to use a value
stored in a variable?
t.n.a.
