SQL 2005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' );
