Looking at this method call that gets used when constructing the SQL INSERT statements when writing data from a dynamic schema to a database, I think it's missing a case to handle null numeric types.
It already has 2 cases for handling DATE and TIME entries, but could do with one or more to cater for numeric values.
This would stop the problem where a null integer column in a dynamic schema is getting changed to a 0 (zero).
Thanks for raising this @dsoulalioux. Would you mind raising issues like this here: https://jira.talendforge.org. Every issue raised in Jira will be assessed and worked on if found to be required, whereas an issue raised here can easily be missed by R&D.
