ELT
Syntax
ELT(N, str1[, str2, str3,...])
Description
Takes a numeric argument and a series of string arguments. Returns the string that corresponds to the given numeric position. For instance, it returns str1
if N
is 1, str2
if N
is 2, and so on. If the numeric argument is a FLOAT
, MariaDB rounds it to the nearest INTEGER
. If the numeric argument is less than 1, greater than the total number of arguments, or not a number, ELT()
returns NULL
. It must have at least two arguments.
It is complementary to the FIELD()
function.
Examples
SELECT ELT(1, 'ej', 'Heja', 'hej', 'foo'); +------------------------------------+ | ELT(1, 'ej', 'Heja', 'hej', 'foo') | +------------------------------------+ | ej | +------------------------------------+ SELECT ELT(4, 'ej', 'Heja', 'hej', 'foo'); +------------------------------------+ | ELT(4, 'ej', 'Heja', 'hej', 'foo') | +------------------------------------+ | foo | +------------------------------------+
