Wrong VIEW column data type for COALESCE(int_column)

Details

    Description

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a INT);
      		 
      CREATE OR REPLACE VIEW v1 AS SELECT COALESCE(a) FROM t1;
      		 
      DESCRIBE v1;


      +-------------+------------+------+-----+---------+-------+
      		 
      | Field       | Type       | Null | Key | Default | Extra |
      		 
      +-------------+------------+------+-----+---------+-------+
      		 
      | COALESCE(a) | bigint(11) | YES  |     | NULL    |       |
      		 
      +-------------+------------+------+-----+---------+-------+

      Notice, the column data type is bigint. The expected data type is int, like in the table t1.
