interface XBlob

Description

is the 代表 (mapping) of an SQL BLOB .

A SQL BLOB is a built-in type that 蓄える／店s a Binary Large 反対する as a column value in a 列／漕ぐ／騒動 of a database （米）棚上げする／（英）提議する. The driver 器具／実施するs BLOB using a SQL locator(BLOB) , which means that a Blob 反対する含む／封じ込めるs a 論理（学）の pointer to the SQL BLOB data rather than the data itself.
A Blob 反対する is valid for the duration of the 処理／取引 in which is was created.

Methods in the interfaces XResultSet , and XPreparedStatement , such as getBlob and setBlob 許す a programmer to 接近 the SQL BLOB .
The Blob interface 供給するs methods for getting the length of a SQL BLOB (Binary Large 反対する) value, for materializing a BLOB value on the （弁護士の）依頼人 and for 決定するing the position of a pattern of bytes within a BLOB value.

Methods' 要約
length	returns the number of bytes in the BLOB value 指定するd by this `Blob` 反対する.
getBytes	returns as an array of bytes part or all of the BLOB value that this `Blob` 反対する指定するs. The byte array 含む／封じ込めるs up to `length` 連続した bytes starting at position `pos`.
getBinaryStream	retrieves the BLOB 指定するd by this `Blob` instance as a stream.
position	決定するs the byte position at which the 明示するd byte `pattern` begins within the BLOB value that this `Blob` 反対する代表するs. The search for `pattern` begins at position `start` .
positionOfBlob	決定するs the byte position in the BLOB value 指定するd by this `Blob` 反対する at which `pattern` begins. The search begins at position `start` .

Methods' 詳細（に述べる）s

length

hyper
length()
raises(	SQLException );

Description: returns the number of bytes in the BLOB value 指定するd by this Blob 反対する.
Returns: the length
Throws: SQLException if a database 接近 error occurs.

getBytes

sequence< byte >
getBytes(	[in] hyper	pos,
	[in] long	length )
raises(	SQLException );

Description: returns as an array of bytes part or all of the BLOB value that this Blob 反対する指定するs. The byte array 含む／封じ込めるs up to length 連続した bytes starting at position pos.
Parameter pos: is the ordinal position of the first byte in the BLOB value to be 抽出するd; the first byte is at position 1.
Parameter length: is the number of 連続した bytes to be copied.
Returns: a byte array 含む／封じ込めるing up to length 連続した bytes from the BLOB value 指定するd by this Blob 反対する, starting with the byte at position pos .
Throws: SQLException if there is an error 接近ing the BLOB .

getBinaryStream

::com::sun::星／主役にする::io::XInputStream
getBinaryStream()
raises(	SQLException );

Description: retrieves the BLOB 指定するd by this Blob instance as a stream.
Returns: the stream
Throws: SQLException if a database 接近 error occurs.

position

hyper
position(	[in] sequence< byte >	pattern,
	[in] hyper	start )
raises(	SQLException );

Description: 決定するs the byte position at which the 明示するd byte pattern begins within the BLOB value that this Blob 反対する代表するs. The search for pattern begins at position start .
Parameter pattern: the pattern to search
Returns: the position
Throws: SQLException if a database 接近 error occurs.

positionOfBlob

hyper
positionOfBlob(	[in] XBlob	pattern,
	[in] hyper	start )
raises(	SQLException );

Description: 決定するs the byte position in the BLOB value 指定するd by this Blob 反対する at which pattern begins. The search begins at position start .
Parameter pattern: the pattern to search
Parameter start: position to start
Returns: the position
Throws: SQLException if a database 接近 error occurs.
