Obtenir texte sql d'un UDT

Question

Lors de la création d'une fonction ou d'un déclencheur, vous pouvez trouver la commande de création en sys.sql_modules

Mais ce que je ne peux pas sembler trouver est la même pour UDT.

Lorsque je crée un type comme celui-ci

CREATE TYPE dbo.UserIds AS TABLE (value int NOT NULL PRIMARY KEY); 

il ne montre pas en sys.sql_modules.

La seule information que je peux trouver est de sys.types

select * from sys.types where is_user_defined = 1 

mais il n'y a pas d'instruction SQL. Alors, où puis-je le trouver?

Answer 1

Vous pouvez obtenir des informations sur le type de table et colonnes de métadonnées:

CREATE TYPE dbo.UserIds AS TABLE (value int NOT NULL PRIMARY KEY); 

-- 
DECLARE @name SYSNAME = 'UserIds'; 

SELECT sch = SCHEMA_NAME(t.schema_id) 
    ,t.name 
    ,type  = TYPE_NAME(t.user_type_id) 
    ,c.name 
    ,col_type = TYPE_NAME(c.user_type_id) 
    ,c.is_nullable 
    --.... more info about max_length (if text) and so on 
FROM sys.table_types t 
JOIN sys.columns c 
    ON t.type_table_object_id = c.object_id 
WHERE t.name = @name; 

Sur la base de cette information, vous pouvez recréer instruction DDL.

EDIT:

Si vous voulez script, il le plus simple est d'utiliser SSMS. Right-click ->Script object as (même chose pour les types simples).

Answer 2

Les types et les UDT n'apparaissent pas dans sys.objects ou dans sys.sql_modules, simplement parce qu'ils ne sont pas des modules mais des types.

Pour obtenir le script d'un UDT, vous devez rejoindre sys.types avec sys.schemas, sur le champ schema_id. et encore vous devez faire un peu d'analyse et de conversion je suppose.

Answer 3

Ce n'est pas si simple d'obtenir une définition de type, vous pouvez prouver à vous-même ly lancer Profiler et demander SSMS pour générer un script CREATE pour votre type.
