获取UDT的sql文本

Question

创建函数或触发器时，可以在sys.sql_modules

中找到其创建命令

但是我似乎无法找到的是UDT的相同内容。

当我创建这样的类型时

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

它没有显示在sys.sql_modules。

我能找到的唯一信息来自sys.types

select * from sys.types where is_user_defined = 1

但没有SQL语句。那我在哪里找到它？

Answer 1

您可以从元数据中获取有关表类型和列的信息：

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;

根据该信息，您可以重新创建DDL语句。

修改

如果您想编写脚本，最简单的方法是使用SSMS。 Right-click - ＆gt; Script object as（简单类型相同）。

Answer 2

获取类型定义并不是那么简单，您可以自己证明启动Profiler并要求SSMS为您的类型生成一个CREATE脚本。

这就是我所拥有的：

这是为了让你知道它有多复杂

Answer 3

类型和UDT不会出现在sys.objects或sys.sql_modules中，只是因为它们不是模块而是类型。

用于获取UDT的脚本，您必须在schema_id字段上使用sys.schemas加入sys.types。我想你还需要做一些解析和转换。
