SYSADMIN.getResourceDependencies

Given a resource name, this system procedure returns all its dependencies:

SQL

CREATE FOREIGN PROCEDURE getResourceDependencies(IN resourceName string NOT NULL, IN resourceType string, IN dependencyType string, OUT dependentResourceName string NOT NULL RESULT, OUT dependentResourceType string NOT NULL, OUT parentResourceName string, OUT parentResourceType string, OUT permissionRoleName string, OUT permissionText string)

It takes the following parameters:

Parameter Description

resourceName

The name of the resource in question. Must include schema name.

A '*' can be used to return all dependencies (the default dependency type is used).

resourceType

Can take one of the following values:

PROC: if the resource is a procedure
SCHEMA: if the resource is a schema
TABLE: if the resource is a table
VIEW: if the resource is a view

dependencyType

Optional, can take one of the following values:

CHILDREN: (default) to return child objects
PARENTS: to return parent objects

Examples

1. All descendants of all elements of the schema are shown, but with only those parent objects which belong to this schema:

SQL

SELECT * FROM (CALL SYSADMIN.getResourceDependencies('sch_a', 'SCHEMA')) AS a;

2. All descendants of the table are shown, but with this table as a parent and only those other parent objects which are descendants of this table:

SQL

SELECT * FROM (CALL SYSADMIN.getResourceDependencies('sch_a.test_a', 'TABLE')) AS a;

3. All descendants of view are shown, but with this view as a parent and only those other parents which are descendants of this view:

SQL

SELECT * FROM (CALL SYSADMIN.getResourceDependencies('sch_a.v_a2', 'VIEW')) AS a;

4. All descendants of the procedure are shown, but with this procedure as a parent and only those other parent objects which are descendants of this procedure:

SQL

SELECT * FROM (CALL SYSADMIN.getResourceDependencies('sch_a.pr_a3', 'PROC')) AS a;

5. The full dependency graph is shown:

SQL

SELECT * FROM (CALL SYSADMIN.getResourceDependencies('*', null)) AS a;
 
// or

SELECT * FROM (CALL SYSADMIN.getResourceDependencies(resourceName => '*')) AS a;

6. All child objects of the view are shown:

SQL

SELECT * FROM (CALL SYSADMIN.getResourceDependencies('sch_a.v_a2', 'VIEW', 'CHILDREN')) AS a;

7. All parent objects of the view are shown:

SQL

SELECT * FROM (CALL SYSADMIN.getResourceDependencies('sch_a.v_a2', 'VIEW', 'PARENTS')) AS a;

SYSADMIN.getViewAndProcCreationOrder

This system procedure gets the creation order of views and procedures:

SQL

SYSADMIN.getViewAndProcCreationOrder(OUT creationOrder string NOT NULL RESULT)

Example

SQL

SELECT * FROM (CALL SYSADMIN.getViewAndProcCreationOrder()) AS p
