What is VARBINARY data type?
The VARBINARY type is similar to the VARCHAR type, but stores binary byte strings rather than non-binary character strings. It contains no character set, and comparison and sorting are based on the numeric value of the bytes.
When would you use VARBINARY data type?
When N is not specified with the CAST function, the default length is 30. VARBINARY(MAX) data type is used to store images/pdf/word etc files and any data. The maximum permissible key length is 900 bytes for creating the Index. Index can’t be created on BINARY data type if the data length above 900 bytes.

What is the difference between VARBINARY and binary?
Both BINARY and VARBINARY are both binary byte data types. BINARY stores values in fixed lengths. Values are padded with 0x00. VARBINARY stores values in variable lengths.
Is VARBINARY a blob?
Ultimately, VARBINARY is virtually the same as BLOB (from the perspective of what can be stored in it), unless you want to preserve compatibility with “old” versions of MySQL. In most respects, you can regard a BLOB column as a VARBINARY column that can be as large as you like.
What is VARBINARY Max?
varbinary [ ( n | max) ] Variable-length binary data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of the data entered + 2 bytes. The data that is entered can be 0 bytes in length.
What is the difference between binary and VARBINARY?
Both BINARY and VARBINARY are both binary byte data types. But they have the following major differences: BINARY stores values in fixed lengths. VARBINARY stores values in variable lengths.
