SQL Server服务器 访问ADO


  平常我们只听说过ADO等一类ASP对象,但在ASP中还有个鲜为人知的专门SQL Server的ASP访问对象,它就是SQLOLE.SQLServer对象。SQLOLE.SQLServer可以直接访问SQL Server的系统属性。以Set oSQLServer = CreateObject ("SQLOLE.SQLServer")语句将产生一个SQL Server服务器对象。
  
  若要查看此服务器中数据库的集合,可用语句:
  For Each SQLDB In oSQLServer.Databases
  Response.Write SQLDB.Name ‘将列出所有的数据库,如Pubs等
  Next
  
  若要查看某数据库中(如PUBS数据库)数据表的集合,可用语句:
  
  pubDatabase=oSQLServer.Databases(“pubs”)
  ’oSQLServer是前面创建的SQL Server服务器对象
  For Each DBTable In pubDatabase.Tables
  Response.Write DBTable.Name
  Next
  
  下面的语句将列出数据库中(PUBS数据库)数据视图
  
  pubDatabase =oSQLServer.Databases(“pubs”)
  ’oSQLServer是前面创建的SQL Server服务器对象
  For Each DBView In pubDatabase.Views
  Response.Write DBView.Text
  Next
  
  以下语句将列出数据库中(PUBS数据库)存贮过程
  
  pubDatabase =oSQLServer.Databases(“pubs”)
  ’oSQLServer是前面创建的SQL Server服务器对象
  For Each DBSP In pubDatabase.StoredProcedures
  Response.Write DBSP.Text
  Next
  
  程序运行的结果(取数据表名):
  
  取存贮过程的结果:

  列出 IE5 所支持的所有server端变量
  
  以下是MSDN (1999年4月版)提供的 IE5 所支持的所有server端变量
  部分变量在以前的版本中不支持,而且在以后的版本中可能会有变化(这是Microsoft的原话)
  
  Variable Description
  ALL_HTTP All HTTP headers sent by the client.
  ALL_RAW Retrieves all headers in the raw-form. The difference between ALL_RAW and ALL_HTTP is that ALL_HTTP places an HTTP_ prefix before the header name and the header-name is always capitalized. In ALL_RAW the header name and values appear as they are sent by the client.
  APPL_MD_PATH Retrieves the metabase path for the (WAM) Application for the ISAPI DLL.
  APPL_PHYSICAL_PATH Retrieves the physical path corresponding to the metabase path. IIS converts the APPL_MD_PATH to the physical (directory) path to return this value.
  AUTH_PASSWORD The value entered in the client's authentication dialog. This variable is only available if Basic authentication is used.
  AUTH_TYPE The authentication method that the server uses to validate users when they attempt to access a protected script.
  AUTH_USER Raw authenticated user name.
  CERT_COOKIE Unique ID for client certificate, Returned as a string. Can be used as a signature for the whole client certificate.
  CERT_FLAGS bit0 is set to 1 if the client certificate is present.
  bit1 is set to 1 if the Certificate Authority of the client certificate is invalid (not in the list of recognized CA on the server).
  
  CERT_ISSUER Issuer field of the client certificate (O=MS, OU=IAS, CN=user name, C=USA).
  CERT_KEYSIZE Number of bits in Secure Sockets Layer connection key size. For example, 128.
  CERT_SECRETKEYSIZE Number of bits in server certificate private key. For example, e.g. 1024.
  CERT_SERIALNUMBER Serial number field of the client certificate.
  CERT_SERVER_ISSUER Issuer field of the server certificate.
  CERT_SERVER_SUBJECT Subject field of the server certificate.
  CERT_SUBJECT Subject field of the client certificate.
  CONTENT_LENGTH The length of the content as given by the client.
  CONTENT_TYPE The data type of the content. Used with queries that have attached information, such as the HTTP queries GET, POST, and PUT.
  GATEWAY_INTERFACE The revision of the CGI specification used by the server. The format is CGI/revision.
  HTTP_<HeaderName> The value stored in the header HeaderName. Any header other than those listed in this table must be prefixed by HTTP_ in order for the ServerVariables collection to retrieve its value.
  Note The server interprets any underscore (_) characters in HeaderName as dashes in the actual header. For example if you specify HTTP_MY_HEADER, the server searches for a header sent as MY-HEADER.
  
  HTTP_ACCEPT Returns the value of the Accept header.
  HTTP_ACCEPT_LANGUAGE Returns a string describing the language to use for displaying content.
  HTTP_USER_AGENT Returns a string describing the browser that sent the
