db2 jdbc

hi all,
how do I insert "VARCHAR FOR BIT DATA" via jdbc?
I like to create from an ResaultSet (from a table) Insert-Statements.

How do I hanlde the Field-Types?
Does someone have an example in java?

Thank you very much....

You can use the "setBinaryStream" method of the PreparedStatement
class/interface or the "setBytes" method. Alternatively, convert the
binary data to its hex representation and use:

x'...'

in the SQL statement where the ... is the string with the hex
representation.

.... and what is the difference between CAHR FOR BIT DATA and VARCAHR
For BIT DATA.
(is there a difference in the insert?)

Well, the same difference as with CHAR and VARCHAR: one has a fixed length
and the other a flexible length. If the stream that you provide to DB2 for
a CHAR FBD column is too short, it will be padded with spaces, i.e. with
trailing x'20' bytes.

a new question to that topic:
could I insert the hex-string with PreparedStatements ?
