CopyFromBFILE (OraLOB) Method

Applies To

Description

Copies a portion or all of the LOB value of an OraBFILE object to the LOB value of this object.

Usage

OraBlob.CopyFromBFile srcBFile, amount, destOffset, srcOffset
 
OraClob.CopyFromBFile srcBFile, amount, destOffset, srcOffset

Arguments

The arguments for the method are:

Arguments	Description
[`in`] `srcBFile`	An `OraBFILE` object from which the data is to be copied.
[`in`] [optional] `amount`	An `Integer` specifying the maximum number to be copied, in characters for `OraCLOB` or bytes for `OraBLOB` or `OraBFILE`. Default value is the size of `BFILE` value of the `srcBFile` object.
[`in`] [optional] `destOffset`	An `Integer` specifying the absolute offset for this instance. Default is `1`.
[`in`] [optional] `srcOffset`	An `Integer` specifying the absolute offset for the `BFILE` value of the source `OraBFILE` object. Default is `1`.

Remarks

Obtain either a row-level lock or object-level lock before calling this method.

For a single-byte character set, the OraBFile object should be of the same character set as the database.

If the database has a variable width character set, the OraBFile object passed to the OraClob.CopyFromBFile method must point to a file that uses the UCS2 character set.
