GRANT (user defined extension)

Grants privileges on a user-defined extensions (UDx) to users and roles.

Grants privileges on a user-defined extensions (UDx) to users and roles.

Syntax

GRANT { privilege[,...] | ALL [ PRIVILEGES ] [ EXTEND ] }
   ON {
       UDx-type [[database.]schema.]function( [arg-list] )[,...]
       | ALL FUNCTIONS IN SCHEMA schema[,...] }
   TO grantee[,...]
   [ WITH GRANT OPTION ]

Arguments

privilege
The following privileges are valid for user-defined extensions:
ALL [PRIVILEGES] [EXTEND]
Grants all function privileges that also belong to the grantor. Grantors cannot grant privileges that they themselves lack

You can qualify ALL with two optional keywords:

  • PRIVILEGES conforms with the SQL standard.

  • EXTEND extends the semantics of ALL to include ALTER and DROP privileges. An unqualified ALL excludes these two privileges. This option enables backward compatibility with GRANT ALL usage in pre-9.2.1 Vertica releases.

ON UDx-type
Type of the user-defined extension (UDx), one of the following:

  • FUNCTION (scalar function)

  • AGGREGATE FUNCTION

  • ANALYTIC FUNCTION

  • TRANSFORM FUNCTION

  • FILTER

  • PARSER

  • SOURCE

[database.]schema

Database and schema. The default schema is public. If you specify a database, it must be the current database.

function
Name of the user-defined function on which to grant privileges.
ON ALL FUNCTIONS IN SCHEMAschema
Grants privileges on all functions in the specified schema.
arg-list
Required for all polymorphic functions, a comma-delimited list of function arguments, where each argument is specified as follows: 
[ argname ] argtype

If the procedure is defined with no arguments, supply an empty argument list.

grantee

Specifies who is granted privileges, one of the following:

WITH GRANT OPTION

Gives grantee the privilege to grant the same privileges to other users or roles, and also revoke them. For details, see Granting privileges.

Privileges

Non-superusers require USAGE on the schema and one of the following:

  • Owner

  • Privileges grantee given the option (WITH GRANT OPTION) of granting privileges to other users or roles.

Examples

Grant EXECUTE privileges on the myzeroifnull SQL function to users Bob and Jules, and to the role Operator. The function takes one integer argument:

=> GRANT EXECUTE ON FUNCTION myzeroifnull (x INT) TO Bob, Jules, Operator;

Grant EXECUTE privileges on all functions in the zero-schema schema to user Bob:

=> GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA zero-schema TO Bob;

Grant EXECUTE privileges on the tokenize transform function to user Bob and the role Operator:

=> GRANT EXECUTE ON TRANSFORM FUNCTION tokenize(VARCHAR) TO Bob, Operator;

Grant EXECUTE privileges on the ExampleSource() source to user Alice:

=> CREATE USER Alice;
=> GRANT USAGE ON SCHEMA hdfs TO Alice;
=> GRANT EXECUTE ON SOURCE ExampleSource() TO Alice;

Grant all privileges on the ExampleSource() source to user Alice:

=> GRANT ALL ON SOURCE ExampleSource() TO Alice;

Grant all privileges on polymorphic function Pagerank to the dbadmin role:

=> GRANT ALL ON TRANSFORM FUNCTION Pagerank(z varchar) to dbadmin;
