![]() In some obscure cases it may be necessary to use the underlying operator names instead. Long String String = "select count(*) from expedia_region_union where (region_name_full ILIKE '%' || :whatEverRegionName || '%' or region_name_full_kr ILIKE '%' || :whatEverRegionName || '%')", nativeQuery = true) The phrases LIKE, ILIKE, NOT LIKE, and NOT ILIKE are generally treated as operators in PostgreSQL syntax for example they can be used in expression operator ANY ( subquery) constructs, although an ESCAPE clause cannot be included there. List String int int = "select count(*) from expedia_region_union where region_type = :regionType and (region_name_full ILIKE '%' || :whatEverRegionName || '%' or region_name_full_kr ILIKE '%' || :whatEverRegionName || '%')", nativeQuery = true) 기존 쿼리 = "select * from expedia_region_union where (region_name_full ILIKE '%' || :whatEverRegionName || '%' or region_name_full_kr ILIKE '%' || :whatEverRegionName || '%') ORDER BY region_id ASC limit :limitValue offset :offsetValue", nativeQuery = true) All of these operators are PostgreSQL-specific. Re: PATCH Use indexes on the subscriber when REPLICA IDENTITY is full on the publisher - Mailing list pgsql-hackers From: Amit Kapila: Subject: Re: PATCH Use indexes on the subscriber when. There are also !~~ and !~~* operators that represent NOT LIKE and NOT ILIKE, respectively. Postgres Pro Enterprise Postgres Pro Standard Cloud Solutions Postgres Extensions. The operator ~~ is equivalent to LIKE, and ~~* corresponds to ILIKE. This is not in the SQL standard but is a PostgreSQL extension. We have seen LIKE examples in my previous blog posts. If Postgres expects to find enough rows so that some data pages in the main relation would have to be visited more than once (obviously the case with rows10591544 ), it switches from index scan to bitmap index scan - which is followed by a 'Bitmap Heap Scan' to fetch actual tuples. However, you can try if it works on other types of indexes.- 너무 느림 The key word ILIKE can be used instead of LIKE to make the match case-insensitive according to the active locale. Postgres LIKE and ILIKE operators are used in pattern matching. Currently, these indexes will work on BTREE ONLY.This is because a hypothetical index does not exist in reality. If you wish to run an EXPLAIN ANALYZE that runs that SQL and provides the run time stats, it would not be able to use that hypothetical index.The only way to see if we can benefit from that index is by running an EXPLAIN.As for the ILIKE, PostgreSQL cannot natively (but see below for a module that can) use an index as long as your wildcard is the first character. ![]() This seems to be eating up 92 of your cost estimate and is likely what's making it run for so long. None of the catalog tables nor the original tables are actually touched. If there is already an index available, PostgreSQL is choosing not to use it for some reason.
