如何通过单个查询获取所有用户定义数据类型的脚本。

试试这个：
SET NOCOUNT ON
SELECT 'USE ' + QUOTENAME(DB_NAME(), '[') + '
GO';
SELECT '
IF EXISTS (SELECT * FROM sys.types st JOIN sys.schemas ss ON st.schema_id = ss.schema_id WHERE st.name = N''' + st.[name] + ''' AND ss.name = N''' + ss.[name] + ''')
DROP TYPE ' + QUOTENAME(ss.name, '[') + '.' + QUOTENAME(st.name, '[') + '
GO
CREATE TYPE ' + QUOTENAME(ss.name, '[') + '.' + QUOTENAME(st.name, '[') + ' FROM ' +
QUOTENAME(bs.[name], '[') +
CASE bs.[name]
WHEN 'char' THEN (CASE ISNULL(st.max_length, 0) WHEN 0 THEN '' WHEN -1 THEN '(MAX)' ELSE '(' + convert(varchar(10), st.max_length) + ')' END)
WHEN 'nchar' THEN (CASE ISNULL(st.max_length, 0) WHEN 0 THEN '' WHEN -1 THEN '(MAX)' ELSE '(' + convert(varchar(10), st.max_length/2) + ')' END)
WHEN 'varchar' THEN (CASE ISNULL(st.max_length, 0) WHEN 0 THEN '' WHEN -1 THEN '(MAX)' ELSE '(' + convert(varchar(10), st.max_length) + ')' END)
WHEN 'nvarchar' THEN (CASE ISNULL(st.max_length, 0) WHEN 0 THEN '' WHEN -1 THEN '(MAX)' ELSE '(' + convert(varchar(10), st.max_length/2) + ')' END)
WHEN 'numeric' THEN (CASE ISNULL(st.[precision], 0) WHEN 0 THEN '' ELSE '(' + convert(varchar(10), st.[precision]) + ', ' + convert(varchar(10), st.[scale]) + ')' END)
WHEN 'decimal' THEN (CASE ISNULL(st.[precision], 0) WHEN 0 THEN '' ELSE '(' + convert(varchar(10), st.[precision]) + ', ' + convert(varchar(10), st.[scale]) + ')' END)
WHEN 'varbinary' THEN (CASE st.max_length WHEN -1 THEN '(max)' ELSE '(' + convert(varchar(10), st.max_length) + ')' END)
ELSE ''
END +
'
GO
'
FROM sys.types st
INNER JOIN sys.schemas ss ON st.[schema_id] = ss.[schema_id]
INNER JOIN sys.types bs ON bs.[user_type_id] = st.[system_type_id]
WHERE st.[is_user_defined] = 1 -- exclude system types
ORDER BY st.[name], ss.[name]
免责声明：我不是此脚本的作者。只是我在我的个人图书馆里有它。不幸的是，作者的名字并不存在。

除了vmvadivel所说的（它就像魅力!!）这是一个为你做的脚本，只需将代码转储到那里并命名sql文件getTypesSelect.sql，这将起作用：
@echo off
cls
set /p SName=Server Name :
set /p UName=User Name :
set /p Pwd=Password :
set /p DbName=Database Name :
set /p choice=ARE YOU SURE TO EXECUTE SCRIPTS in %DbName% (y/n) ?
if '%choice%'=='y' goto begin
goto end
:begin
if exist addUserDefinedTypes.sql del addUserDefinedTypes.sql
@echo on
SQLCMD -S %SName% -d %DbName% -U %UName% -i "getTypesSelect.sql" -o addUserDefinedTypes.txt -P %Pwd%
rename addUserDefinedTypes.txt addUserDefinedTypes.sql
@notepad addUserDefinedTypes.sql
:end
如果您计划在不同的数据库（您可能会）上运行，请从上面的sql查询中删除以下行
SELECT 'USE ' + QUOTENAME(DB_NAME(), '[') + '
GO';

这是一个实际起作用的脚本。
为所有用户定义的标量和表类型创建脚本（未经CLR类型测试）：
