I'm getting an error when updating contact addresses:
Failed to do query: Incorrect integer value: '' for column 'refid' at row 1
In query: REPLACE INTO address VALUES ('',2,'','','','','','',0,'55584862341','','','')
The empty string can no longer to converted to a numeric.
This has been mentioned in the forums but not logged as a bug:
This is relevant to MySql 5.0. When tab3 wants to insert a null to a decimal or integer field, the default value supplied is an empty string. MySql 5.0 behaves differently to MySql 4 in that it doesn't automatically convert this to 0.
I've implemented a workaround for the issue by adding the following statement to the query method on the DB class.
set sql_mode = '';
It now works with MySql 5.0.
