From 15beeef6ce762b7c9b7e360e4367738406b28a63 Mon Sep 17 00:00:00 2001 From: Sarah Hoffmann Date: Tue, 1 Mar 2022 08:54:15 +0100 Subject: [PATCH] do not expand records in select list An expression of the form 'SELECT (func()).*' will be expanded by Postgresql _before_ execution with the result that the function will be called as many times as there are fields in the record. This is not what we want. The function call needs to go into the FROM clause instead. --- lib-sql/functions/placex_triggers.sql | 15 +++++++++------ nominatim/indexer/runners.py | 5 +++-- nominatim/tokenizer/icu_tokenizer.py | 2 +- nominatim/tokenizer/legacy_tokenizer.py | 2 +- 4 files changed, 14 insertions(+), 10 deletions(-) diff --git a/lib-sql/functions/placex_triggers.sql b/lib-sql/functions/placex_triggers.sql index 6ab3e84d..1eae353e 100644 --- a/lib-sql/functions/placex_triggers.sql +++ b/lib-sql/functions/placex_triggers.sql @@ -342,9 +342,10 @@ BEGIN WHERE s.place_id = parent_place_id; FOR addr_item IN - SELECT (get_addr_tag_rank(key, country)).*, key, + SELECT ranks.*, key, token_get_address_search_tokens(token_info, key) as search_tokens - FROM token_get_address_keys(token_info) as key + FROM token_get_address_keys(token_info) as key, + LATERAL get_addr_tag_rank(key, country) as ranks WHERE not token_get_address_search_tokens(token_info, key) <@ parent_address_vector LOOP addr_place := get_address_place(in_partition, geometry, @@ -456,10 +457,12 @@ BEGIN address_havelevel := array_fill(false, ARRAY[maxrank]); FOR location IN - SELECT (get_address_place(partition, geometry, from_rank, to_rank, - extent, token_info, key)).*, key - FROM (SELECT (get_addr_tag_rank(key, country)).*, key - FROM token_get_address_keys(token_info) as key) x + SELECT apl.*, key + FROM (SELECT extra.*, key + FROM token_get_address_keys(token_info) as key, + LATERAL get_addr_tag_rank(key, country) as extra) x, + LATERAL get_address_place(partition, geometry, from_rank, to_rank, + extent, token_info, key) as apl ORDER BY rank_address, distance, isguess desc LOOP IF location.place_id is null THEN diff --git a/nominatim/indexer/runners.py b/nominatim/indexer/runners.py index 76bd3b31..ac7a0015 100644 --- a/nominatim/indexer/runners.py +++ b/nominatim/indexer/runners.py @@ -45,8 +45,9 @@ class AbstractPlacexRunner: @staticmethod def get_place_details(worker, ids): - worker.perform("""SELECT place_id, (placex_indexing_prepare(placex)).* - FROM placex WHERE place_id IN %s""", + worker.perform("""SELECT place_id, extra.* + FROM placex, LATERAL placex_indexing_prepare(placex) as extra + WHERE place_id IN %s""", (tuple((p[0] for p in ids)), )) diff --git a/nominatim/tokenizer/icu_tokenizer.py b/nominatim/tokenizer/icu_tokenizer.py index f5c66bc0..1799ae86 100644 --- a/nominatim/tokenizer/icu_tokenizer.py +++ b/nominatim/tokenizer/icu_tokenizer.py @@ -590,7 +590,7 @@ class LegacyICUNameAnalyzer(AbstractAnalyzer): continue with self.conn.cursor() as cur: - cur.execute("SELECT (getorcreate_full_word(%s, %s)).*", + cur.execute("SELECT * FROM getorcreate_full_word(%s, %s)", (token_id, variants)) full, part = cur.fetchone() diff --git a/nominatim/tokenizer/legacy_tokenizer.py b/nominatim/tokenizer/legacy_tokenizer.py index 7ce6b242..28f4b327 100644 --- a/nominatim/tokenizer/legacy_tokenizer.py +++ b/nominatim/tokenizer/legacy_tokenizer.py @@ -515,7 +515,7 @@ class _TokenInfo: simple_list = list(set(simple_list)) with conn.cursor() as cur: - cur.execute("SELECT (create_housenumbers(%s)).* ", (simple_list, )) + cur.execute("SELECT * FROM create_housenumbers(%s)", (simple_list, )) self.data['hnr_tokens'], self.data['hnr'] = cur.fetchone() -- 2.39.5
