sql HTTP端点

　SQL2005提供了一个新的执行存储过程或者T-SQL的方法,它可以以WEB服务的方式发布到服务器上,而无须使用IIS 这个新特点通过HTTP API把HTTP端点暴露给用户,在WINXP SP2和WIN2003上被支持。
　　建立一个HTTP端点是非常简单的,如下：
CREATE ENDPOINT MyEndpoint?
STATE = STARTED
AS HTTP (
AUTHENTICATION = (INTEGRATED),
PATH = '/sql/myendpoint',
PORTS = (CLEAR) )
FOR SOAP (
BATCHES = ENABLED,
WSDL = DEFAULT
)

在上面的案例中我建立一个命名为MyEndpoint的端点,它在http://localhost/sql/myendpoint监听T-SQL语句,你可以使用下面URL测试它
http://localhost/sql/myendpoint?wsdl.
　　上面这个URL还可以附加很丰富的参数,具体参见SQL帮助
　　下面这个例子显示如何通过JAVSCRIPT来调用端点执行T-SQL语句,如下:
function SendBatchRequest( strServerName, strUrlPath, strQuery )
{
var objXmlHttp = null;
var strRequest = "";
objXmlHttp = new ActiveXObject( "microsoft.xmlhttp" );
objXmlHttp.open( "POST", "http://" + strServerName + strUrlPath, false );
objXmlHttp.setrequestheader( "Content-Type", "text/xml" );
objXmlHttp.setRequestHeader( "Host", strServerName );
strRequest = "＜SOAP-ENV:Envelope xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/'
xmlns:sql='http://schemas.microsoft.com/sqlserver/2004/SOAP'＞
＜SOAP-ENV:Body＞
＜sql:sqlbatch＞
＜sql:BatchCommands＞" + strQuery + "＜/sql:BatchCommands＞
＜/sql:sqlbatch＞
＜/SOAP-ENV:Body＞
＜/SOAP-ENV:Envelope＞";
objXmlHttp.send( strRequest );
if( objXmlHttp.status == 200 )
return objXmlHttp.responseXML.xml;
else
return "";
}
var response = SendBatchRequest( 'localhost', '/sql/myendpoint', 'Select * from sys.http_endpoints' )
