After an Update to 4.9.21 I got the message in the install tool to set the database to strict mode. So I did. Afterwards I couldn't create any content element and got the following error message:
An exception occurred while executing 'INSERT INTO tl_content (floating, perRow, rsts_content_type, rsts_template, pid, sorting, ptable, tstamp) VALUES ('left', '', 'rsts_default', 'rsts_default', 10, 28, 'tl_article', 0)': SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect integer value: '' for column xb1_db.tl_content.perRow at row 1
I deactivated the strict mode again and the error was gone.
