Conditional functions return one of their arguments by evaluating in an if-else
|
|
manner. {esql} supports these conditional functions:
|
|
|
|
// tag::list[]
|
|
* <<esql-case>>
|
|
* <<esql-coalesce>>
|
|
* <<esql-greatest>>
|
|
* <<esql-least>>
|
|
// end::list[]
|
|
|
|
include::case.asciidoc[]
|
|
include::coalesce.asciidoc[]
|
|
include::greatest.asciidoc[]
|
|
include::least.asciidoc[]
