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.
