Methods

o length 
 public long length() throws SQLException
Implements the Blob interface function. The length of the Binary Large OBject in bytes.

Returns:
length of the BLOB in bytes

                      long start) throws SQLException
Implements the Blob interface function. Determine the byte position at which the given byte pattern

Parameters:
pattern - is the pattern to search for.
start - is the position at which to begin searching.
Returns:
the position at which the pattern appears, else -1.
o position 
 public long position(Blob pattern,
                      long start) throws SQLException
Implements the Blob interface function. Determine the byte position at which the given pattern

Parameters:
searchstr - is the pattern to search for.
start - is the position at which to begin searching.
Returns:
the position at which the pattern appears, else -1.
o getBytes

 public int putBytes(long pos,
                     byte bytes[]) throws SQLException
Oracle extension. Put data to the BLOB at the requested position.

Parameters:
pos - is the position data to be put.
bytes - is the data to be written into BLOB.
Returns:
the number of bytes actually written.
o getBinaryOutputStream 
 public OutputStream getBinaryOutputStream() throws SQLException
Oracle extension. Write to the BLOB from a stream.

Returns:
a output stream to write data to the BLOB

if any of the lower layer code throws an exception.
o isConvertibleTo 
 public boolean isConvertibleTo(Class jClass)
Oracle extension. Test whether this data object can be converted to the specified Java data type.

Parameters:
jClass specifies - the Java data type to test against.
Returns:
true if this data object is convertible to the specified Java class, and a corresponding xxxValue() method is available; otherwise, a false is returned.
