[GitHub] [doris] luozenglin opened a new pull request, #15271: [fix](Inbitmap) fix in bitmap result error when left expr is constant
luozenglin opened a new pull request, #15271:
URL: https://github.com/apache/doris/pull/15271
1. When left expr of the in predicate is a constant, instead of generating a bitmap filter, rewrite sql to use `bitmap_contains`. For example,"select k1, k2 from (select 2 k1, 11 k2) t where k1 in (select bitmap_col from bitmap_tbl)" => "select k1, k2 from (select 2 k1, 11 k2) t left semi join bitmap_tbl b on bitmap_contains(b.bitmap_col, t.k1)"
