ALTER FILTER

Alters a user-defined filter.

Syntax

ALTER FILTER [[db-name.]schema.]function‑name( [ parameter‑list ] ) {
    OWNER TO new‑owner
    | RENAME TO new‑name
    | SET FENCED boolean‑expr
    | SET SCHEMA new‑schema
}

Parameters

[db-name.]schema

Specifies a schema, by default public. If schema is any schema other than public, you must supply the schema name. For example:

myschema.thisDbObject

If you specify a database, it must be the current database.
function‑name Name of the function to alter.
parameter‑list Comma-delimited list of parameters that are defined for this function. If none, specify an empty list.

Vertica supports function overloading, and uses the parameter list to identify the function to alter.

OWNER TO new‑owner Transfers function ownership to another user.
RENAME TO new‑name Renames this function.
SET FENCED { true | false } Specifies whether to enable fenced mode for this function.
SET SCHEMA new‑schema Moves the function to another schema.

Privileges

Non-superuser: USAGE on the schema and one of the following:

  • Function owner
  • ALTER privilege on the function

For certain operations, non-superusers must also have the following schema privileges:

Operation Schema privileges required
RENAME TO (rename function) CREATE, USAGE
SET SCHEMA (move function to another schema)

  • CREATE: destination schema
  • USAGE: current schema
