SHOW ERRORS
This statement shows errors from previously executed statements. The error buffer is cleared as soon as a statement executes successfully. In which case, SHOW ERRORS will return an empty set.
The behavior of which statements generate errors vs. warnings is highly influenced by the current sql_mode.
