>>-BLOB--(--string-expression--+------------+--)---------------><
'-,--integer-'
The BLOB function returns a BLOB representation of a string
of any type.
- string-expression
- A string-expression whose value can be a character string,
graphic string, or a binary string.
- integer
- An integer value specifying the length attribute of the resulting
BLOB data type. If integer is not specified, the length attribute
of the result is the same as the length of the input, except where
the input is graphic. In this case, the length attribute of the result
is twice the length of the input.
The result of the function is a BLOB. If the argument
can be null, the result can be null; if the argument is null, the
result is the null value.
