ADD_RULE Procedure

Adds the specified rule to the specified rule set.

To run this procedure, a user must meet at least one of the following requirements:

Have ALTER_ON_RULE_SET privilege on the rule set
Have ALTER_ANY_RULE_SET system privilege
Be the owner of the rule set

Also, the rule set owner must meet at least one of the following requirements:

Have EXECUTE_ON_RULE privilege on the rule
Have EXECUTE_ANY_RULE system privilege
Be the rule owner

If the rule has no evaluation context and no evaluation context is specified when you run this procedure, then rule uses the evaluation context associated with the rule set. In such a case, the rule owner must have the necessary privileges on all the base objects accessed by the rule using the evaluation context.

If an evaluation context is specified, then the rule set owner must meet at least one of the following requirements:

Have EXECUTE_ON_EVALUATION_CONTEXT privilege on the evaluation context
Have EXECUTE_ANY_EVALUATION_CONTEXT system privilege, and the owner of the evaluation context must not be SYS
Be the evaluation context owner

If the evaluation context owner is different than the rule owner, then the rule owner must have the necessary privileges on all the base objects accessed by the rule using the evaluation context.

Syntax

DBMS_RULE_ADM.ADD_RULE(
   rule_name           IN  VARCHAR2,
   rule_set_name       IN  VARCHAR2,
   evaluation_context  IN  VARCHAR2   DEFAULT NULL,

Parameters

Table 64-2 ADD_RULE Procedure Parameters

Parameter	Description
`rule_name`	The name of the rule you are adding to the rule set, specified as `[``schema_name``.]``rule_name`. For example, to add 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 to which you are adding the rule, specified as `[``schema_name``.]``rule_set_name`. For example, to add the rule to 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`	An evaluation context name in the form `[``schema_name``.]``evaluation_context_name`. If the schema is not specified, then the current user is the default. Only specify an evaluation context if the rule itself does not have an evaluation context and you do not want to use the rule set's evaluation context for the rule.
`rule_comment`	Optional description, which may contain the reason for adding the rule to the rule set

Parameters

Table 64-3 ALTER_RULE Procedure Parameters (Page 1 of 2)

Parameter	Description
`rule_name`	The name of the rule you are altering, specified as `[``schema_name``.]``rule_name`. For example, to alter 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.
`condition`	The Boolean condition to be associated with the rule. If non-`NULL`, then the rule's condition is changed.
`evaluation_context`	An evaluation context name in the form `[``schema_name``.]``evaluation_context_name`. If the schema is not specified, then the current user is the default. If non-`NULL`, then the rule's evaluation context is changed.
`remove_evaluation_context`	If `true`, then sets the evaluation context for the rule to `NULL`, which effectively removes the evaluation context from the rule. If `false`, then retains any evaluation context for the specified rule. If the `evaluation_context` parameter is non-`NULL`, then this parameter should be set to `false`.
`action_context`	If non-`NULL`, then changes the action context associated with the rule. A rule action context is information associated with a rule that is interpreted by the client of the rules engine when the rule is evaluated.
`remove_action_context`	If `true`, then sets the action context for the rule to `NULL`, which effectively removes the action context from the rule. If `false`, then retains any action context for the specified rule. If the `action_context` parameter is non-`NULL`, then this parameter should be set to `false`.
`rule_comment`	If non-`NULL`, then changes the description of the rule
`remove_rule_comment`	If `true`, then sets the comment for the rule to `NULL`, which effectively removes the comment from the rule. If `false`, then retains any comment for the specified rule. If the `rule_comment` parameter is non-`NULL`, then this parameter should be set to `false`.

    grant_option => false);
END;
/

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

Removes the specified rule from the specified rule set.

To run this procedure, a user must meet at least one of the following requirements:

Have ALTER_ON_RULE_SET privilege on the rule set
Have ALTER_ANY_RULE_SET system privilege
Be the owner of the rule set

Note:
This procedure does not drop a rule from the database. To drop a rule from the database, use the DROP_RULE procedure.

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 64-14 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 an error is raised. 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 an error is raised.
`all_evaluation_contexts`	If `true`, then the rule is removed from the rule set with all of its associated evaluation contexts.
