    Description

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL(30,1)) ENGINE=ColumnStore;
      		 
      INSERT INTO t1 VALUES (1);
      		 
      SELECT SEC_TO_TIME(a), SEC_TO_TIME(a)+0.0 FROM t1;


      +----------------+--------------------+
      		 
      | SEC_TO_TIME(a) | SEC_TO_TIME(a)+0.0 |
      		 
      +----------------+--------------------+
      		 
      | 00:00:01.0     |                0.0 |
      		 
      +----------------+--------------------+

      Notice, SEC_TO_TIME(a) per se returned a correct result, but when I further put it into a DECIMAL plus operation, it returned 0.

      The expected result is:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL(30,1)) ENGINE=InnoDB;
      		 
      INSERT INTO t1 VALUES (1);
      		 
      SELECT SEC_TO_TIME(a), SEC_TO_TIME(a)+0.0 FROM t1;


      +----------------+--------------------+
      		 
      | SEC_TO_TIME(a) | SEC_TO_TIME(a)+0.0 |
      		 
      +----------------+--------------------+
      		 
      | 00:00:01.0     |                1.0 |
      		 
      +----------------+--------------------+
