ShowFunctionsCommand

case class ShowFunctionsCommand(db: Option[String], pattern: Option[String], showUserFunctions: Boolean, showSystemFunctions: Boolean) extends LeafNode with RunnableCommand with Product with Serializable

A command for users to list all of the registered functions. The syntax of using this command in SQL is:

SHOW FUNCTIONS [LIKE pattern]

For the pattern, '*' matches any sequence of characters (including no characters) and '|' is for alternation. For example, "show functions like 'yea*|windo*'" will return "window" and "year".
