RESTRICT ROWS

Configures the column used for row-level access control.

Configures the column used for row-based access control; you can only define one Primary Key column. If the column is already configured, running the RESTRICT ROWS command replaces the definition.
Tip: Use DESCRIBE TABLE to view the existing restrictions on the table.

  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 is case-sensitive.
