| COPY BLOB ( srcBLOB ; dstBLOB ; srcOffset ; dstOffset ; len ) | ||||||||
| Parameter | Type | Description | ||||||
| srcBLOB | BLOB |

Number of bytes to be copied | |||||
The COPY BLOB command copies the number of bytes specified by len from the BLOB srcBLOB to the BLOB dstBLOB.
The copy starts at the position (expressed relative to the beginning of the source BLOB) specified by srcOffset and takes place at the position (expressed relative to the beginning of the destination BLOB) specified by dstOffset.
Note: The destination BLOB can be resized if necessary.
