Functions

build_object_group_for_delete 🔒

Build a object group for notifying the deletion of the given objects.

check_connection_name_duplicate

check_connection_name_duplicate checks whether the connection name is already used in the target namespace.

check_database_name_duplicate

check_database_name_duplicate checks whether the database name is already used in the cluster.

check_function_signature_duplicate

check_function_signature_duplicate checks whether the function name and its signature is already used in the target namespace.

check_object_refer_for_drop

check_object_refer_for_drop checks whether the object is used by other objects except indexes. It returns an error that contains the details of the referring objects if it is used by others.

check_relation_name_duplicate

check_relation_name_duplicate checks whether the relation name is already used in the target namespace.

check_schema_name_duplicate

check_schema_name_duplicate checks whether the schema name is already used in the target database.

check_secret_name_duplicate

check_sink_into_table_cycle

Check if create a sink with given dependent objects into the target table will cause a cycle, return true if it will.

check_subscription_name_duplicate

check_user_name_duplicate

check_user_name_duplicate checks whether the user is already existed in the cluster.

compose_dispatchers

construct_obj_dependency_query

This function will construct a query using recursive cte to find all objects[(id, obj_type)] that are used by the given object.

construct_privilege_dependency_query

construct_privilege_dependency_query constructs a query to find all privileges that are dependent on the given one.

construct_sink_cycle_check_query

This function will construct a query using recursive cte to find if dependent objects are already relying on the target table.

ensure_object_id

ensure_object_id ensures the existence of target object in the cluster.

ensure_privileges_not_referred

ensure_privileges_not_referred ensures that the privileges are not granted to any other users.

ensure_schema_empty

ensure_schema_empty ensures that the schema is empty, used by DROP SCHEMA.

ensure_user_id

ensure_user_id ensures the existence of target user in the cluster.
