9.2 ResultSet.getBytes()

•

The separator can be cleared by passing either a null object or empty String as the parameter

to oracle.jdbc.rdb.common.Blob.setSegSeparator().

The JDBC standard limits the use of the ResultSet.getBytes() methods for access to

BINARY, VARBINARY and LONGVARBINARY data. The Oracle JDBC for Rdb drivers

relax this limitation and will attempt to return byte arrays for all valid SQL data types using

these methods.

Using getBytes() on:

CHAR and VARCHAR columns will return the raw data as returned by Rdb to the

driver.

Numeric, columns will be returned in their Rdb Native format as a big-endian array

of bytes.

Date, and time will be returned as 64 bit big-endian array of bytes.
