Provides a testing mechanism when setting up proxy roles by running CQL commands as another role during a CQL shell session.

To start, use EXECUTE AS <role_name>. The commands run with the permissions of the specified role. To stop, use EXECUTE AS without a role name.

Requires PROXY.EXECUTE on the specified role, see GRANT ROLE.


EXECUTE AS [ <role_name> ]
Syntax legend
Syntax conventions Description


Literal keyword.


Not literal.

< >

Variable value. Replace with a user-defined value.


Optional. Square brackets ([]) surround optional command arguments. Do not type the square brackets.

( )

Group. Parentheses ( ( ) ) identify a group to choose from. Do not type the parentheses.


Or. A vertical bar (|) separates alternative elements. Type any one of the elements. Do not type the vertical bar.


Repeatable. An ellipsis ( ... ) indicates that you can repeat the syntax element as often as required.

'<Literal string>'

Single quotation (') marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case.

{ <key> : <value> }

Map collection. Braces ({ }) enclose map collections or key value pairs. A colon separates the key and the value.


Set, list, map, or tuple. Angle brackets ( < > ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.


End CQL statement. A semicolon (;) terminates all CQL statements.


Separate the command line options from the command arguments with two hyphens ( -- ). This syntax is useful when arguments might be mistaken for command line options.

' <<schema\> ... </schema\>> '

Search CQL only: Single quotation marks (') surround an entire XML schema declaration.


Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrConfig files.


The name of the role to run the commands as. The commands run with the permissions of the specified role.


Use the read_race role to execute commands:

EXECUTE AS read_race;
Executing queries as read_race.

Perform a query:

FROM cycling.race_times;
 race_name                   | race_time | cyclist_name
 17th Santos Tour Down Under |  19:15:18 | Rohan DENNIS
 17th Santos Tour Down Under |  19:15:20 | Richie PORTE
 17th Santos Tour Down Under |  19:15:38 |  Cadel EVANS
 17th Santos Tour Down Under |  19:15:40 | Tom DUMOULIN
