What is a Varbinary data type?

The VARBINARY data type stores the variable-length binary data with a maximum length of 8,000 bytes. It is very much like BINARY, except the physical column size differs depending on the value stored. If the length is not specified, the default is 1.

Similarly one may ask, 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.

Additionally, 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.

In this way, what does Varbinary look like?

Description. The VARBINARY type is similar to the VARCHAR type, but stores binary byte strings rather than non-binary character strings. M represents the maximum column length in bytes. It contains no character set, and comparison and sorting are based on the numeric value of the bytes.

Is binary column mysql?

The BINARY and VARBINARY types are similar to CHAR and VARCHAR , except that they store binary strings rather than nonbinary strings. That is, they store byte strings rather than character strings.
