RESTRICT

Configures the column on which permissions can be granted.

Tables have only a single restriction. Running the RESTRICT command replaces the existing restriction. Use DESCRIBE TABLE to view the existing restrictions on the table. The column must be part of the partition key.

Synopsis

RESTRICT ROWS 
  ON [keyspace_name.]table_name 
  USING pk_column_name ;

Table 1. Legend
Syntax conventions	Description
UPPERCASE	Literal keyword.
Lowercase	Not literal.
`Italics`	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.
`<datatype1,datatype2>`	Set, list, map, or tuple. Angle brackets ( `< >` ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.
`cql_statement;`	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.
`@xml_entity='xml_entity_type'`	Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrConfig files.

Examples

For the cyclist_expenses table, configure the cyclist_name column for filtering so that permissions can be assigned. In this example, we identify the column so that each cyclist can view only their own expenses:

RESTRICT ROWS ON cyclist_expenses USING cyclist_name;

RLAC requires two commands: a single RESTRICT and one or more GRANT commands. For example, cyclist Vera Adrian can view her expenses:

GRANT SELECT ON 'Vera ADRIAN' ROWS IN cyclist_expenses TO cycling_accounts;

Note: The filtering_data string is case-sensitive.
