Added in: 2.1
Description
Returns the rightmost part of the argument string. The number of characters is given in the second argument.
Result type: VARCHAR or BLOB
Syntax
RIGHT (string, length)
This function supports text BLOBs of any length, but has a bug in versions 2.1–2.1.3 that makes it fail with text BLOBs larger than 1024 bytes that have a multi-byte character set. This has been fixed in version 2.1.4.
If string is a BLOB, the result is a BLOB. Otherwise, the result is a VARCHAR(n) with n the length of the input string.
If the length argument exceeds the string length, the input string is returned unchanged.
If the length argument is not a whole number, bankers' rounding (round-to-even) is applied, i.e. 0.5 becomes 0, 1.5 becomes 2, 2.5 becomes 2, 3.5 becomes 4, etc.
Warning: When used on a BLOB, this function may need to load the entire object into memory. This may affect performance if huge BLOBs are involved.
Important: If the external function RIGHT is declared in your database, it will override the internal function. To make the internal function available, DROP or ALTER the external function (UDF).
