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                                |
+------------------------------------+
