      Description

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (i INT, d DECIMAL(10,1)) ENGINE=ColumnStore;
      		 
      INSERT INTO t1 VALUES (0, 1.5);
      		 
      UPDATE t1 SET i=d;


      ERROR 1264 (22003): CAL0002: IDB-2025: Data truncated for column 'i'

      Looks wrong. It should round decimal to int without errors, like InnoDB does:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (i INT, d DECIMAL(10,1)) ENGINE=InnoDB;
      		 
      INSERT INTO t1 VALUES (0, 1.5);
      		 
      UPDATE t1 SET i=d;
      		 
      SELECT * FROM t1;


      +------+------+
      		 
      | i    | d    |
      		 
      +------+------+
      		 
      |    2 |  1.5 |
      		 
      +------+------+
