What is VARGRAPHIC DB2 data type?

When columns contain double-byte character set (DBCS) characters, you can define them as either graphic data or mixed data. Graphic data can be either GRAPHIC, VARGRAPHIC, or DBCLOB. Using VARGRAPHIC saves disk space, but it incurs a 2-byte overhead cost for each value.

What is CLOB datatype in DB2?

Stands for “Character Large Object.” A CLOB is a data type used by various database management systems, including Oracle and DB2. It stores large amounts of character data, up to 4 GB in size. Since CLOB data may be very large, some database management systems do not store the text directly in the table.

What is graphic string in DB2?

A graphic string is a sequence of code units that represents double-byte character data. The length of the string is the number of code units in the sequence. If the length is zero, the value is called the empty string. Graphic strings are not supported in a database that is defined with a single-byte code page.

What is the size of BLOB in DB2?

A binary large object (BLOB) is a varying-length string with a maximum length of 2 147 483 647 bytes (2 gigabytes minus 1 byte). A BLOB is designed to store non-traditional data such as pictures, voice, and mixed media. BLOBs can also store structured data for use by distinct types and user-defined functions.

Which is better BLOB or CLOB?
