Method Detail

setBytes

public int setBytes(long pos,
                    byte[] bytes)
             throws SQLException

Writes the given array of bytes to the BLOB value that this Blob object represents, starting at position pos, and returns the number of bytes written.

Parameters:

pos - the position in the BLOB object at which to start writing

bytes - the array of bytes to be written to the BLOB value that this Blob object represents

Returns:

the number of bytes written

Throws:

SQLException - if there is an error accessing the BLOB value

Since:

1.4

setBytes

public int setBytes(long pos,
                    byte[] bytes,
                    int offset,
                    int len)
             throws SQLException

Writes all or part of the given byte array to the BLOB value that this Blob object represents and returns the number of bytes written. Writing starts at position pos in the BLOB value; len bytes from the given byte array are written.

Parameters:

pos - the position in the BLOB object at which to start writing

bytes - the array of bytes to be written to this BLOB object

offset - the offset into the array bytes at which to start reading the bytes to be set

len - the number of bytes to be written to the BLOB value from the array of bytes bytes

Returns:

the number of bytes written

Throws:

SQLException - if there is an error accessing the BLOB value

Since:

1.4
