Find a more recent version at Firebird 5.0 Language Reference: Binary Data Types
Changed in: 2.0
Description: Several enhancements have been implemented for text BLOBs:
DML COLLATE clauses are now supported.
Equality comparisons can be performed on the full BLOB contents.
Character set conversions are possible when assigning a BLOB to a BLOB or a string to a BLOB.
When defining binary BLOBs, the mnemonic
binary
can now be used instead of the integer 0.
Examples:
select NameBlob from MyTable where NameBlob collate pt_br = 'João'
create table MyPictures ( id int not null primary key, title varchar(40), description varchar(200), picture blob sub_type binary )
