It is very much like BINARY which holds fixed-length of data in column and both data types have default value 1 if length is not specified. That is, they store byte strings rather than character strings. varbinary : The name as it suggests, stores variable-length data. SET. Broadly speaking there are two major categories within which the different string types can be divided, and understanding these two categories is very important because each of this category is handled differently by MySQL.
