Copying from DECIMAL to YEAR is not consistent about warnings

Details

    • Bug
    • Status: Closed (View Workflow)
    • Major
    • Resolution: Fixed
    • 5.5(EOL), 10.0(EOL), 10.1(EOL), 10.2(EOL)
    • 10.2.0
    • Temporal Types
    • None

    Description

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a YEAR);
      		 
      INSERT INTO t1 VALUES (-0.1);
      		 
      SHOW WARNINGS;

      correctly reports warnings:

      +---------+------+--------------------------------------------+
      		 
      | Level   | Code | Message                                    |
      		 
      +---------+------+--------------------------------------------+
      		 
      | Warning | 1264 | Out of range value for column 'a' at row 1 |
      		 
      +---------+------+--------------------------------------------+

      So does copying:

      DROP TABLE IF EXISTS t1,t2;
      		 
      CREATE TABLE t1 (a YEAR);
      		 
      CREATE TABLE t2 (a DECIMAL(10,1));
      		 
      INSERT INTO t2 VALUES (-0.1);
      		 
      INSERT INTO t1 SELECT * FROM t2;
      		 
      SHOW WARNINGS;

      While ALTER does not return any warnings:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL(10,1));
      		 
      INSERT INTO t1 VALUES (-0.1);
      		 
      ALTER TABLE t1 MODIFY a YEAR;
      		 
      SHOW WARNINGS;

            The same problem is repeatable when converting from DOUBLE to YEAR.
