I am not sure if this is the case.
GDA sets locale to be always C for floating types.
So floats are stored with dot as decimal in MySQL table.
Which is correct.

On data fetching there's locale change too, but point is, MySQL buffer
holds invalid (seems so) data. I used to use MySQL C API, and never had
such problem. Though, I have never used prepared statements.

I wonder if gda_mysql_provider_statement_execute prepare statement
correctly. Neither float nor double is taken into account in this routine.
