  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:   一个完整的小例子源码附后(其它功能读者可加入)。      < %@ LANGUAGE = VBScript % >      < HTML >   < HEAD >   < META NAME="GENERATOR" Content=   "Microsoft Developer Studio" >   < META HTTP-EQUIV="Content-Type"   content="text/html; charset=gb2312" >      < TITLE >< /TITLE >   < /HEAD >      < %   On Error Resume Next   Dim oSQLServer   Set oSQLServer = CreateObject ("SQLOLE.SQLServer")      strServer = "dep"   strLogin = "sa"   strPwd = ""      oSQLServer.Connect strServer,strLogin,strPwd      % >      < BODY BGCOLOR=#ffffff >   数据库列表   < SELECT NAME="Database" >   < %   For Each SQLDB In oSQLServer.Databases   If Not SQLDB.SystemObject Then   Response.Write "< OPTION VALUE=   """ & SQLDB.Name & """ >" & SQLDB.Name      & " "   End If   Next   Set oSQLServer = Nothing   % >   < /SELECT >   < /BODY >   < /HTML >      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:   一个完整的小例子源码附后(其它功能读者可加入)。      < %@ LANGUAGE = VBScript % >      < HTML >   < HEAD >   < META NAME="GENERATOR" Content=   "Microsoft Developer Studio" >   < META HTTP-EQUIV="Content-Type"   content="text/html; charset=gb2312" >      < TITLE >< /TITLE >   < /HEAD >      < %   On Error Resume Next   Dim oSQLServer   Set oSQLServer = CreateObject ("SQLOLE.SQLServer")      strServer = "dep"   strLogin = "sa"   strPwd = ""      oSQLServer.Connect strServer,strLogin,strPwd      % >      < BODY BGCOLOR=#ffffff >   数据库列表   < SELECT NAME="Database" >   < %   For Each SQLDB In oSQLServer.Databases   If Not SQLDB.SystemObject Then   Response.Write "< OPTION VALUE=   """ & SQLDB.Name & """ >" & SQLDB.Name      & " "   End If   Next   Set oSQLServer = Nothing   % >   < /SELECT >   < /BODY >   < /HTML >      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 <
