If you don't have double value field or data, maybe you should try to disable sql strict mode.
To do that you have to edit "my.ini" file located in MySQL installation folder, find "Set the SQL mode to strict" line and change the below line:
# Set the SQL mode to strict
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
to this, deleting "STRICT_TRANS_TABLES"
# Set the SQL mode to strict
sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
After that, you have to restart MySQL service to enable this change.
To check the change, open the editor an execute this sql sentence:
SHOW VARIABLES LIKE 'sql_mode';
Very Important: Be careful of the file format after saving. Save it as "UTF8" and don't as "TFT8 with BOM" because the service will not restart.
