      Description

      When columnstore_select_handler=on this query should return only 2 rows. Instead it returns all rows.

      create database test1;
      use test1;
       
      CREATE TABLE test_table (
      category CHAR(1),
      count INTEGER(1)
      ) ENGINE=COLUMNSTORE;
       
      INSERT INTO test_table (category, count) VALUES ('A', 1);
      INSERT INTO test_table (category, count) VALUES ('A', 2);
      INSERT INTO test_table (category, count) VALUES ('B', 3);
      INSERT INTO test_table (category, count) VALUES ('B', 4);
       
      set columnstore_select_handler=off;
      select * FROM (
      SELECT count / SUM(count) OVER (PARTITION BY category) AS ratio
      FROM test_table
      ) a
      where ratio > .5;
      ratio
      0.6667
      0.5714
       
      set columnstore_select_handler=on;
      select * FROM (
      SELECT count / SUM(count) OVER (PARTITION BY category) AS ratio
      FROM test_table
      ) a
      where ratio > .5;
      ratio
      0.6667
      0.3333
      0.5714
      0.4286
