SQL Server：检查表是否存在

Question

我正在尝试检查通过openquery访问的表是否存在以下代码，但它不起作用：

    IF EXISTS (SELECT * FROM OPENQUERY(SADATABASE, ' select     *
                           from xx_201509_T                           ' 
            ) )

Answer 1

尝试这样的事情：

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[xx_201509_T]') AND type in (N'U'))
***DO WHATEVER HERE***

Answer 2

SELECT OBJECT_ID('xx_201509_T', 'U') 

如果是NULL，则表格不存在

编辑：所以在你的openquery中使用它是这样的：

IF (SELECT objectID FROM OPENQUERY(SADATABASE, 'SELECT OBJECT_ID(''xx_201509_T'', ''U'') as objectID') )  IS NOT NULL 
BEGIN
 print 'xx_201509_T TABLE EXISTS'
END
