SQL SERVER系统表应用之基于Table生成存储过程参数列表

有时一个Table有很多列，你需要写一个存储过程，那个Table的参数列表够你写的了。我们可以利用系统表生成这个列表，看T-SQL:

select '@' + c.name, col_definition =
case t.name
when 'bigint' then 'bigint,'
when 'int' then 'int,'
when 'smallint' then 'smallint,'
when 'tinyint' then 'tinyint,'
when 'bit' then 'bit,'
when 'decimal' then 'decimal,'
when 'numeric' then 'numeric,'
when 'money' then 'money,'
when 'smallmoney' then 'smallmoney,'
when 'float' then 'float,'
when 'real' then 'real,'
when 'datetime' then 'datetime,'
when 'smalldatetime' then 'smalldatetime,'
when 'sql_variant' then 'sql_variant,'
when 'timestamp' then 'timestamp,'
when 'uniqueidentifier' then 'uniqueidentifier,'
when 'xml' then 'xml,'
else t.name + '(' + cast(c.prec as varchar(50)) + '),'
end
from sysobjects s
inner join sys.syscolumns c on s.id = c.id
inner join sys.types t on t.user_type_id = c.xtype
where s.xtype='U'
and s.name = 'Product'

结果是：

(No column name) col_definition
@ProductID int,
@Name nvarchar(50),
@ProductNumber nvarchar(25),
@MakeFlag bit,
@FinishedGoodsFlag bit,
@Color nvarchar(15),
@SafetyStockLevel smallint,
@ReorderPoint smallint,
@StandardCost money,
@ListPrice money,
@Size nvarchar(5),
@SizeUnitMeasureCode nchar(3),
@WeightUnitMeasureCode nchar(3),
@Weight decimal,
@DaysToManufacture int,
@ProductLine nchar(2),
@Class nchar(2),
@Style nchar(2),
@ProductSubcategoryID int,
@ProductModelID int,
@SellStartDate datetime,
@SellEndDate datetime,
@DiscontinuedDate datetime,
@rowguid uniqueidentifier,
@ModifiedDate datetime,

这里我使用的Table来自AdventureWorks，完了，这么简单。
