2005年Sql服务器书写稿。 我正在登记一个图象。
CREATE XML SCHEMA COLLECTION [dbo].[MySchema] AS N <xsd:schema ... >

DROP XML SCHEMA COLLECTION [dbo].[MySchema]

DROP ...
CREATE ...
但是,这在Schema没有存在的情况下就是一个第一行的问题。 我愿做一些类似的事情。
IF OBJECT_ID ( MySchema ) IS NOT NULL
DROP ...
CREATE ...
但OBJECT_ID (MySchema ) 。 在2005年Sql服务器中是否有经登记的Xml Schema藏书的适当检验方法?
:
IF EXISTS (SELECT * FROM sys.xml_schema_collections WHERE name = MySchema )
