От публикуване през На сайта на DBA Бях близо до отговора, който търсех. Tom Kyte има страхотна публикация в блог с функция, която прави точно това, на което се надявах. Накратко, ето какво внедрих:
Създадох функция, която взе sys_refcursor като променлива:
CREATE OR REPLACE FUNCTION fncRefCursor2HTML(rf SYS_REFCURSOR) RETURN CLOB
IS
lRetVal CLOB;
lHTMLOutput XMLType;
lXSL CLOB;
lXMLData XMLType;
lContext DBMS_XMLGEN.CTXHANDLE;
BEGIN
-- get a handle on the ref cursor --
lContext := DBMS_XMLGEN.NEWCONTEXT(rf);
-- setNullHandling to 1 (or 2) to allow null columns to be displayed --
DBMS_XMLGEN.setNullHandling(lContext,1);
-- create XML from ref cursor --
lXMLData := DBMS_XMLGEN.GETXMLTYPE(lContext,DBMS_XMLGEN.NONE);
-- this is a generic XSL for Oracle's default XML row and rowset tags --
-- " " is a non-breaking space --
lXSL := lXSL || q'[<?xml version="1.0" encoding="ISO-8859-1"?>]';
lXSL := lXSL || q'[<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">]';
lXSL := lXSL || q'[ <xsl:output method="html"/>]';
lXSL := lXSL || q'[ <xsl:template match="/">]';
lXSL := lXSL || q'[ <html>]';
lXSL := lXSL || q'[ <body>]';
lXSL := lXSL || q'[ <table border="1">]';
lXSL := lXSL || q'[ <tr bgcolor="cyan">]';
lXSL := lXSL || q'[ <xsl:for-each select="/ROWSET/ROW[1]/*">]';
lXSL := lXSL || q'[ <th><xsl:value-of select="name()"/></th>]';
lXSL := lXSL || q'[ </xsl:for-each>]';
lXSL := lXSL || q'[ </tr>]';
lXSL := lXSL || q'[ <xsl:for-each select="/ROWSET/*">]';
lXSL := lXSL || q'[ <tr>]';
lXSL := lXSL || q'[ <xsl:for-each select="./*">]';
lXSL := lXSL || q'[ <td><xsl:value-of select="text()"/> </td>]';
lXSL := lXSL || q'[ </xsl:for-each>]';
lXSL := lXSL || q'[ </tr>]';
lXSL := lXSL || q'[ </xsl:for-each>]';
lXSL := lXSL || q'[ </table>]';
lXSL := lXSL || q'[ </body>]';
lXSL := lXSL || q'[ </html>]';
lXSL := lXSL || q'[ </xsl:template>]';
lXSL := lXSL || q'[</xsl:stylesheet>]';
-- XSL transformation to convert XML to HTML --
lHTMLOutput := lXMLData.transform(XMLType(lXSL));
-- convert XMLType to Clob --
lRetVal := lHTMLOutput.getClobVal();
RETURN lRetVal;
END;
След това да го тествате в тестов прозорец в PL/SQL Developer
declare
l_cursor sys_refcursor;
begin
open l_cursor for select * from employees;
:x:= fncRefCursor2HTML(l_cursor);
close l_cursor;
end;
Това е нещо, което се надявах да намеря от дълго време. БЛАГОДАРЯ, Том Кайт!
