=== SHOW FUNCTIONS
.Synopsis:
[source, sql]
----
SHOW FUNCTIONS [LIKE pattern]? <1>
----
<1> SQL match pattern
*Description*: List all the SQL functions and their type. The `LIKE` clause can be used to restrict the list of names to the given pattern.
[source, sql]
----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctions]
----
The list of functions returned can be customized based on the pattern.
It can be an exact match:
[source, sql]
----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctionsLikeExact]
----
A wildcard for exactly one character:
[source, sql]
----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctionsLikeChar]
----
A wildcard matching zero or more characters:
[source, sql]
----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctionsLikeWildcard]
----
Or of course, a variation of the above:
[source, sql]
----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctionsWithPattern]
----
