hi,
here is a quick example : (data from url returns as a clob. you need to write it at db. and call from forms.)
FUNCTION Get_DataFromUrl(pUrl IN VARCHAR2,pProxy IN VARCHAR2,pData IN OUT CLOB) RETURN NUMBER IS
vRcv UTL_HTTP.HTML_PIECES;
vData CLOB;
eNoDataReceived EXCEPTION;
BEGIN
UTL_HTTP.SET_DETAILED_EXCP_SUPPORT(TRUE);
-- Get data pieces from Url
vRcv := UTL_HTTP.REQUEST_PIECES(pUrl,Proxy => pProxy);
IF vRcv.COUNT < 1 THEN
RAISE eNoDataReceived;
ELSE
-- Append varchar2 table data into clob variable
DBMS_LOB.CreateTemporary(vData,FALSE,DBMS_LOB.CALL);
FOR i IN 1..vRcv.COUNT LOOP
DBMS_LOB.WriteAppend(vData,LENGTH(vRcv(i)),vRcv(i));
END LOOP;
-- Copy local data into return variable
DBMS_LOB.Copy(pData,vData,DBMS_LOB.GetLength(vData));
DBMS_LOB.FreeTemporary(vData);
END IF;
RETURN SUCCESS;
EXCEPTION
WHEN eNoDataReceived THEN
RETURN FAILURE;
WHEN UTL_HTTP.INIT_FAILED THEN
RETURN FAILURE;
WHEN UTL_HTTP.Request_Failed THEN
RETURN FAILURE;
WHEN OTHERS THEN
RETURN FAILURE;
END Get_DataFromUrl;
hope this helps.
