The next table lists the large-object types, all of which are reference types.

Type Limits Comments
BLOB 1 byte to 2 gigabytes An instance of type BLOB is binary data.
CLOB 1 byte to 2 gigabytes An instance of type CLOB is character data.

You can use a variable of a large-object type to read data to and write data from an equivalent kind of column in a relational database. And as described in “Loblib library,” you can use a variable of a large-object type to reference data in a file and to update that file.
