    Description

      This script:

      SET timestamp=UNIX_TIMESTAMP('2001-01-01 10:20:30.000000');
      		 
      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL(30,0));
      		 
      INSERT INTO t1 VALUES (CURRENT_TIMESTAMP(6));
      		 
      SELECT * FROM t1;

      returns:

      +----------------+
      		 
      | a              |
      		 
      +----------------+
      		 
      | 20010101102030 |
      		 
      +----------------+

      This is correct.

      Now if I do:

      SET timestamp=UNIX_TIMESTAMP('2001-01-01 10:20:30.000000');
      		 
      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL(30,0));
      		 
      INSERT INTO t1 VALUES (COALESCE(CURRENT_TIMESTAMP(6)));
      		 
      SELECT * FROM t1;

      it generates a warning on INSERT, and returns:

      +------+
      		 
      | a    |
      		 
      +------+
      		 
      | 2001 |
      		 
      +------+
