导读: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 '
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。 Author: Petter Liu http://wintersun.cnblogs.com (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
