Обсуждение: NULL values and Java JDBC

Hello,

Columns may contain NULL values. The ecpg for pre-compiling ESQL/C code
has an option to let return NULL values in CHAR columns as empty strings ""
and INTEGER as INT_MIN (-0x7fffffff - 1) values. Is there a similar
option for Java JDBC?

Thanks

I was thinking more in a general setting of such feature (like ecpg does
it for ESQL/C) and not addressing such problem on any single statement
or object.
