Having trouble calling Oracle stored procedure in java -

-

i'm having trouble calling oracle stored procedure in java. added stored procedure database this:

         string sql = "create or replace procedure liveresults() " +                     "is " +                     "begin" +                             " select pool_id, pool_mbr_id, bsln_cd, pge_typ_nm, serv_nm, cl_file_nm" +                             " lbmadm.tppo_mstr_map " +                             " order serv_nm" +                             " pge_typ_nm = 'live' ; " +                     "end";                      stmtlive = con.createstatement();                     stmtlive.executeupdate(sql);

and i'm trying call :

callablestatement cs;                   try {                          cs = con.preparecall("{call liveresults() }");                          rs = cs.executequery();                           while (rs.next()) {  .....

however, i'm getting following errors:

 java.sql.sqlexception: ora-06550: line 1, column 7:  pls-00905: object ut9j.generate_sql_for_live invalid  ora-06550: line 1, column 7:  pl/sql: statement ignored

i can't quite figure out i'm going wrong. read oracle's documentation on , believe did right, guess not. if can shed light on situation i'd appreciate it.

there multiple issues here..

1) why want create procedure inside java code? should create directly in oracle using sqlplus or other database tool.

2) oracle not expect () when there no in/out/in-out parameters, don't need them. need "as" or "is" keyword after "create or replace procedure". otherwise, give compile time error seeing..

  1  create or replace procedure live   2    3  begin   4    null;   ---this have logic,                 --null indicates "do nothing". concentrate on                 --the "declare" issues   5* end; sql> /  procedure created.

3) third error selecting fields table, there no varibles "into" selecting them. 

  1  create or replace procedure live   2    3    v_ename scott.emp.ename%type;   4  begin   5    select ename   6      scott.emp   7      empno = 7369;   8* end; sql> /  warning: procedure created compilation errors.  sql> show errors errors procedure live:  line/col error -------- ----------------------------------------------------------------- 5/3      pls-00428: clause expected in select statement    1  create or replace procedure live   2    3    v_ename scott.emp.ename%type;   4  begin   5    select ename   6      v_ename   7      scott.emp   8      empno = 7369;   9* end; sql> /  procedure created.

4) creating procedure called "live" , calling "liveresults".again, don't need () after procedure call.

5) based on allan's comments below , cybernate's answer(+1), if trying return result set, should open refcursor select , return calling program.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
