Add TIME_ROUND_FRACTIONAL support in ColumnStore

Details

    Description

      ColumnStore currently ignores sql_mode=TIME_ROUND_FRACTIONAL:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL(10,7)) ENGINE=ColumnStore;
      		 
      INSERT INTO t1 VALUES (1.0000006);
      		 
      SET sql_mode=TIME_ROUND_FRACTIONAL;
      		 
      SELECT CAST(a AS TIME(6)) FROM t1;


      +--------------------+
      		 
      | CAST(a AS TIME(6)) |
      		 
      +--------------------+
      		 
      | 00:00:01.000000    |
      		 
      +--------------------+

      The expected result should be:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL(10,7)) ENGINE=MyISAM;
      		 
      INSERT INTO t1 VALUES (1.0000006);
      		 
      SET sql_mode=TIME_ROUND_FRACTIONAL;
      		 
      SELECT CAST(a AS TIME(6)) FROM t1;


      +--------------------+
      		 
      | CAST(a AS TIME(6)) |
      		 
      +--------------------+
      		 
      | 00:00:01.000001    |
      		 
      +--------------------+
