Zero date can be inserted in strict no-zero mode through CREATE TABLE AS SELECT timestamp_field

        Details

        • Type: Bug
        • Status: Closed
        • Priority: Major
        • Resolution: Fixed
        • Affects Version/s: 10.1, 10.0, 5.5

          Description

          set sql_mode=default;
drop table if exists t1;
create table t1 (a timestamp);
insert into t1 values (0);
set sql_mode='TRADITIONAL';
drop table if exists t2;
create table t2 as select * from t1;

          The last statement should fail on error, because zero date is not allowed by sql_mode.

          Note, if I change data time from TIMESTAMP to DATE or DATETIME, it correctly returns the error:

          ERROR 1292 (22007): Incorrect datetime value: '0000-00-00 00:00:00' for column 'a' at row 1
