You can import and export only data of the non-binary, built-in data
types. Derby implicitly
converts the strings to the data type of the receiving column. If any of the
implicit conversions fail, the whole import is aborted. For example, "3+7"
cannot be converted into an integer. An export that encounters a runtime error
stops. Note: You cannot import or export the binary data types: BLOB, CLOB,
CHAR FOR BIT DATA, VARCHAR FOR BIT DATA, or LONG VARCHAR FOR BIT DATA. Additionally,
you cannot import or export the XML data type.
