如何使用SQL查询在SQL SERVER 2008 R2中获取表定义？
我创建了一个示例java程序，在其中我使用以下查询获取所有对象的定义，如视图，触发器，函数等： –
select object_definition(object_id) from sys.objects where type='V'; //for Views select object_definition(object_id) from sys.objects where type='TF'; //for Functions select object_definition(object_id) from sys.objects where type='TR'; //for Triggers select object_definition(object_id) from sys.objects where type='P'; //for Stored Procedures 但是以下查询无法获取表的ddl（表定义）： –
select object_definition(object_id) from sys.objects where type='U'; //for User defined Tables
现在我使用这里给出的解决方案： 使用Query为现有表生成SQL创建脚本以及如何 为现有表 生成CREATE TABLE脚本：第1部分
是否有任何直接的SQL查询使用我可以得到表定义。
看看吧
SELECT * FROM INFORMATION_SCHEMA.TABLES
和
SELECT * FROM INFORMATION_SCHEMA.COLUMNS
我在Tim Chapman找到了这个（ http://www.techrepublic.com/blog/the-enterprise-cloud/script-table-definitions-using-tsql/ ）并做了一些格式化和小修改：
电话很简单
SELECT dbo.CreateScriptTable( 'YourTable',1,1,'NewName',0)
尝试一下：
CREATE FUNCTION dbo.CreateScriptTable ( @TableName SYSNAME, @IncludeConstraints BIT = 1, @IncludeIndexes BIT = 1, @NewTableName SYSNAME = NULL, @UseSystemDataTypes BIT = 0 ) RETURNS VARCHAR(MAX) AS BEGIN DECLARE @MainDefinition TABLE(FieldValue VARCHAR(200));
