IfxBlob classAn IfxBlob represents a BLOB, which is a large block of binary data that allows random access of its contents. You can treat a BLOB in much the same way you treat an operating system file. You can read or write to certain positions in the file without reading or writing through all of the data up to that position.

IfxBlob class

An IfxBlob represents a BLOB, which is a large block of binary data that allows random access of its contents. You can treat a BLOB in much the same way you treat an operating system file. You can read or write to certain positions in the file without reading or writing through all of the data up to that position.

BLOBs and CLOBs, are both types of smart large objects. Both types share many of the same methods. BLOBs differ from CLOBs in that the data in a CLOB is treated as text characters but the data in a BLOB is not. The data in a BLOB is considered to be binary data and no translation or conversion of any kind is performed on it as it is moved to or from the database server.
