[Pljava-dev] char with trailing space, PreparedStatement.setObject & SetString

[Thomas Hallgren]

Hi Jean-Pierre,
I'm not sure this is incorrect behavior. There's nothing in the spec 
that indicates that String values should be trimmed by setString and 
setObject. On the contrary. Some datatypes (the CHAR in particular) are 
sensitive to whitespace according to the SQL standard. Perhaps the 
client jdbc driver is doing something wrong here?

Regards,
Thomas Hallgren
