/

Note:

When you grant a privilege on "ANY" object (for example, ALTER_ANY_RULE), and the initialization parameter O7_DICTIONARY_ACCESSIBILITY is set to FALSE, you give the user access to that type of object in all schemas except the SYS schema. By default, the initialization parameter O7_DICTIONARY_ACCESSIBILITY is set to FALSE.

If you want to grant access to an object in the SYS schema, then you can grant object privileges explicitly on the object. Alternatively, you can set the O7_DICTIONARY_ACCESSIBILITY initialization parameter to TRUE. Then privileges granted on "ANY" object will allow access to any schema, including SYS.


REMOVE_RULE Procedure

This procedure removes the specified rule from the specified rule set.

Syntax

DBMS_RULE_ADM.REMOVE_RULE(
   rule_name                IN  VARCHAR2,
   rule_set_name            IN  VARCHAR2,
   evaluation_context       IN  VARCHAR2  DEFAULT NULL,
   all_evaluation_contexts  IN  BOOLEAN   DEFAULT FALSE);

Parameters

Table 126-15 REMOVE_RULE Procedure Parameters

Parameter Description

rule_name

The name of the rule you are removing from the rule set, specified as [schema_name.]rule_name. For example, to remove a rule named all_a in the hr schema, enter hr.all_a for this parameter. If the schema is not specified, then the current user is the default.

rule_set_name

The name of the rule set from which you are removing the rule, specified as [schema_name.]rule_set_name. For example, to remove the rule from a rule set named apply_rules in the hr schema, enter hr.apply_rules for this parameter. If the schema is not specified, then the current user is the default.

evaluation_context_name

The name of the evaluation context associated with the rule you are removing, specified as [schema_name.]evaluation_context_name. For example, to specify an evaluation context named dept_eval_context in the hr schema, enter hr.dept_eval_context for this parameter. If the schema is not specified, then the current user is the default.

If an evaluation context was specified for the rule you are removing when you added the rule to the rule set using the ADD_RULE procedure, then specify the same evaluation context. If you added the same rule more than once with different evaluation contexts, then specify the rule with the evaluation context you want to remove. If you specify an evaluation context that is not associated with the rule, then the procedure raises an error.

Specify NULL if you did not specify an evaluation context when you added the rule to the rule set. If you specify NULL and there are one or more evaluation contexts associated with the rule, then the procedure raises an error.

all_evaluation_contexts

If TRUE, then the procedure removes the rule from the rule set with all of its associated evaluation contexts.

If FALSE, then the procedure only removes the rule with the specified evaluation context.

This parameter is relevant only if the same rule is added more than once to the rule set with different evaluation contexts.
