Thank you for the bug report. Please check the warning from query you think is OK:

mysql> -- The following runs OK
mysql> SELECT ADRS_ID, CONVERT(STREET_FROM, DECIMAL) AS STREET_FROM, CONVERT(STREET_TO, DECIMAL) AS STREET_TO FROM test.adrs;

I know that these warnings are thrown, but the query I do is intentional in order to retrieve the decinal part of the string, if any, because I want later on to perfrom some calculation on them. However, a warning would be what I would expect from my second query (the one with the insert), rather than a failing error!

Just change your sql_mode to avoid convert warnings on errors:

C:\dbs>c:\dbs\5.6\bin\mysql -uroot --port=3560 --debug-info --prompt="mysql 5.6 > "
