How to create a procedure for REF CURSOR output with any WHERE clause?

I have a requirement like this: I have a huge question that need to reuse in my code over 10 times. This SQL has about 50 lines. Here for these 10 odd times sometimes changes in WHERE clause (columns are the same). So I can't create a view as SQL is not static.

I thought to write a procedure with a para of WHERE_CLAUSE entry. I pulled out a refcursor sys by adding where clause. But I can't do it because you cannot add a clause like this where clause.

i.e.

PROCEDURE dynamyic_query (p_where_clause IN VARCHAR2, p_out_query OUT SYS_REFCURSOR ) IS
BEGIN

  OPEN p_out_query FOR SELECT ......... FROM table WHERE || ' ' || p_where_clause;

END;

The foregoing gives an error.

How to handle such a situation? Any help would be greatly appreciated.

BEGIN
v_stmt := 'SELECT tname FROM tab_test WHERE tname LIKE ''%ABS_V4%'' AND :y';

OPEN p_out_cursor FOR v_stmt using p_where_cluase;

END;

And run this block of code:

declare
v_tname varchar2(200);
out_cursor sys_refcursor;
begin
forms_text_dyn_sql_test(' 1 = 1 ', out_cursor );
LOOP
fetch out_cursor INTO v_tname;
exit when out_cursor%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(v_tname);
END LOOP;
end;
/

I get the error:

[1]: (Error): ORA-00920: invalid relational operator ORA-06512: at "ABS.FORMS_TEXT_DYN_SQL_TEST", line 6 ORA-06512: at line 5

Looks like you can only set column_name =: z, column_name =: values of type y. You can not it seems to replace it with no WHERE CLAUSE?

A bind variable, such as: it, represents a single value.
If: is the VARCHAR2 '1 = 1', then

SELECT tname FROM tab_test WHERE tname LIKE '%ABS_V4%' AND :y

takes the value

SELECT tname FROM tab_test WHERE tname LIKE '%ABS_V4%' AND '1 = 1'

I think you want something like this:

CREATE OR REPLACE PROCEDURE FORMS_TEXT_DYN_SQL_TEST
(     p_where_clause      IN      VARCHAR2
,      p_out_cursor      OUT      SYS_REFCURSOR
) IS
  v_stmt VARCHAR2(1000);
BEGIN
  v_stmt := 'SELECT ename FROM scott.emp WHERE ename LIKE ''%A%'' AND '
          || p_where_clause;

  OPEN p_out_cursor FOR v_stmt;

END;
/
show errors

SET  SERVEROUTPUT  ON

declare
  v_tname varchar2(200);
  out_cursor sys_refcursor;
begin
  forms_text_dyn_sql_test(' 1 = 1 ', out_cursor );
  LOOP
    fetch out_cursor INTO v_tname;
    exit when out_cursor%NOTFOUND;
    DBMS_OUTPUT.PUT_LINE(v_tname);
  END LOOP;
end;
/

How to call a stored procedure with a REF CURSOR output parameter

I'm looking forward to example calling a function/stored procedure with a REF CURSOR output parameter and get the result.
In other words, I have a stored function/procedure that runs a SELECT statement using the OCI library and then he could get the values of each row and each column.

I put a code snippet, it have only the main thing to call a simple stored procedure and to print the name of each column of the cursor, but I couldn t to print out values in the table that calls the stored procedure.
I understand that the next step is to call an OCIStmtFetch.
How to associate the slider with the OCIStmtFetch?

If you need more information, just tell me.

I use ANSI C with HP - UX (HP - UX C) operating system and Oracle 10 g.

Kind regards.

Hi Antonio,.

I see this:

c_buf=(ub1 **)calloc(sizeof(ub1 *),3);

...

rc=OCIDefineByPos(pOciStatCursor,&pdef,(OCIError *)pOciError,pos,c_buf[pos-1],size+1,(ub2)type,(dvoid *)c_indp[pos-1],(ub2 *)0,(ub2 *)0,OCI_DEFAULT);

That I don't understand. You allocate space for 3 pointers ub1 but I don't see where these pointers are then initialized to point to where the data is to be stored.

I do not read correctly?

Sorry for posting code long, but here is an example of code that I have. It is much more 'code' for your code, but maybe that will be enough...

NOTE: This is just the code example and not rigorous. For example, I don't check the memory, allocations etc in this code!

Kind regards

How to create an ERD for the vista sp2 x 64?

If you do not have a Microsoft Vista DVD, make a repair disc to do a Startup Repair:

Download the ISO on the link provided and make a record of repair time it starts.

Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

When you have changed that, insert the Bootable disk you did in the drive and reboot.

http://www.bleepingcomputer.com/tutorials/tutorial148.html

Link above shows what the process looks like and a manual, it load the repair options.

It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

It's a very good Vista startup repair disk.

You can do a system restart tool, system, etc it restore.

It is NOT a disc of resettlement.

How to create a shortcut for all users during installation

Hi people,
We have a desktop application that is distributed with Java Webstart and works on Win7 machines. Initially, users all connected using a connection by default, so creating shortcuts was not a problem. Now, because of new networking strategies, each user has his own connection.
The problem is that the shortcut to the application is created in the user profile (for example "C:\Users\JohnDoe\", so that other users in the same machine can not run the application unless he or she installs the application again.)
Is there a way to create this shortcut for all users using JNLP API or configuration in the xml file?

If anyone has need of the solution: during installation I save the jnlp file in a directory accessible to all the world and then start the application using "javaws path\to\file.jnlp". More details in How to create a shortcut for java webstart available for all users on Windows 7?-stack overflow

How to create unique variables for... in loop? (AS2)

Hello
I have a function onEnterFrame controlling all the movie clips in a table. The movement of each of these clips is controlled by a few variables - speed, acceleration, etc - that are changed on every enterFrame. I can't understand how to create unique variables for each element of the array. Now my variables are the same for all elements, and therefore the proposals of each video clip are the same.
I used this code to add my video clips in the table:
for (i = 0; i < starNumber; i ++) {}
duplicateMovieClip (star, "star" + I, i);
starArray.push (this ["star" + String (i)]);
}
I do a similar thing to create unique variables for each? Or is there something I need to do my loop (myClip in myArray) which is contained in my onEnterFrame function?
I can post my code if that would help (65 lines).

Creating unique variables is easy way out. Here's the modified code using unique variables that should solve your problem:

var i: Number;

var starArray:Array = [];

var starArray_X:Array = [];

var starArray_Y:Array = [];

var mc:String;

var scale: number;

var speedXMod:Number;

var speedYMod:Number;

var starNumber:Number = 10;

var minSize:Number = 15;

var maxSize:Number = 80;

var speed: number = 0.2;

var minSpeed:Number = 0;

var maxSpeed:Number = 1;

for (i = 0; i< starnumber;="">

duplicateMovieClip (star, "star" + I, i);

starArray.push (this ["star" + String (i)]);

}

(MC starArray) {}

starArray [mc] ._x = (Math.Random () * Stage.width);

starArray [mc] ._y = (Math.Random () * Stage.height);

scale = (minSize + (Math.Random () * (maxSize - minSize)));

._xscale starArray [mc] = scale;

starArray [mc] ._yscale = scale;

var startSpeedX:Number = ((Math.pow (-1, (Math.round (Math.random ())) * (minSpeed + (Math.Random () * (maxSpeed - minSpeed)));)))

var startSpeedY:Number = ((Math.pow (-1, (Math.round (Math.random ())) * (minSpeed + (Math.Random () * (maxSpeed - minSpeed)));)))

[mc] starArray_X = startSpeedX;

[mc] starArray_Y = startSpeedY;

onEnterFrame = function() {}

(MC starArray) {}

speedXMod = ((Math.random () * acceleration)-(0,5 * accélération));

speedYMod = ((Math.random () * acceleration)-(0,5 * accélération));

If (((Math.abs (starArray_X [mc] + speedXMod)) < maxspeed)="" &&="" ((math.abs(stararray_x[mc]="" +="" speedxmod))=""> minSpeed)) {}

[mc] starArray_X += speedXMod;

} else {}

[mc] starArray_X = speedXMod;

}

If (((Math.abs (starArray_Y [mc] + speedYMod)) < maxspeed)="" &&="" ((math.abs(stararray_y[mc]+="" speedymod))=""> minSpeed)) {}

[mc] starArray_Y += speedYMod;

} else {}

[mc] starArray_Y = speedYMod;

}

If (((starArray [mc]._x + starArray_X[mc]) > 0) & ((starArray [mc]._x + starArray_X[mc])))<>

starArray [mc] ._x += starArray_X [mc];

} else {}

starArray_X [mc] * = - 1;

starArray [mc] ._x += starArray_X [mc];

}

If (((starArray [mc]._y + starArray_Y[mc]) > 0) & ((starArray [mc]._y + starArray_Y[mc])))<>

starArray [mc] ._y += starArray_Y [mc];

} else {}

starArray_Y [mc] * = - 1;

starArray [mc] ._y += starArray_Y [mc];

}

}

}

How to create a jar for icons
Hi all

How to create a jar for icons? Please help me thanks in advance.

Sarah
Hi Sarah!

To do this, you use at best the jdk (java development kit) which is already
installed on your pc in forms is installed.

Copy all your gif icons in a folder
Open the command prompt and in this folder.

If we assume that you have installed forms in the default directory, call the jar.exe like this:
```
 x:\DevSuiteHome_1\jdk\bin\jar -cfv your_icons.jar *.gif
```
This will create a jar file in the same directory.
Copy the jar file into your x:\DevSuiteHome_1\forms\java folder.

Then open your formsweb.cfg x:\DevSuiteHome_1\forms\server and change your configuration entry under the
```
archive_jini=frmall_jinit.jar
```
TO
```
archive_jini=frmall_jinit.jar, your_icons.jar
```
Please check if in your formsweb.cfg so the imagebase is set to the code base.
If this isn't the case, create a parameter in your config entry:
```
imagebase=codebase
```
Now the jar file is loaded when you start your application and the icons are
turns red from the jar file.

Hello

Find this in your login page:

session_register ("MM_Username");

and then you add a session variable in MX called it:

MM_Username

then on any of your pages that calls the base to make sure that you use the = MM_Username and then you're all set; Make sure that the tables have a field to reference the session MM_Username variable.

'create columns with a where clause' in MDB
Hi all

I have a question on the OBI EE meta data layer.

We have OBIEE sitting on a with a star schema data warehouse.

Our fact table contains the following fields...

EmployeeID
CompanyID
ID of the measure
The measure name
MEASURE

That's what we have in the physical layer, layer MDB and the presentation layer, but I want to be able to "create columns with a where clause.

So my table of facts in the presentation layer would look like this

Quantity sold
Unit cost
Amount of the company

I thought I could just create a logical with column

Quantity = measurement
where as name = "quantity".

But I can't find any to do so.

Any ideas?

Thank you
Hello

I think that what you want to achieve must be done in the physical layer and not the business layer.
Instead of using your physical table directly from the DB, you must create a physical table based on an SQL statement.
GO to the physical layer you / create the new object table in Table type choose "Select" and then you write your select statement as you want.
Once this is done to create your physical joins and import your table into your business layer and create your complex joins
This should do the trick.
It may be useful

The use of bind variables in dynamic query created for Ref Cursor

Hello

I'm in a situation where there is a Ref cursor to which the query is built execution based on a loop. This is why the number of links would be known until the program runs.
The application is currently using literals instead of bind variables.

code snippet of the above is

loop cursor1
If cond is true then
strSql = strSql | "ename = ' |" Cursor1.ColumnName;

What do you mean by "based bind?

He's referring to the coding style. He is currently using concatenated literal, and the goal is to change it to use the bindings.

If I understand this it is known as method 4 dynamic SQL and requires DBMS_SQL. There are examples autour but they vary according to the type of statement being generated - SELECT statements require column lists to be parsed, unlike the INSERT/UPDATE/DELETE.

This came up recently on my current project and I hit a demo. Here a table of names and values accepted procedure and had to build these in a single WHERE clause along the lines of

AND t_names(i) = t_values(i)

for an undetermined number of elements in the array. For this demonstration, I used a table that we called "attribute" (don't ask) which has columns including 'attribute_id' and 'name', and I need to build a query along the lines of

select description from attribute where attribute_id = :b1 and name = :b2

by the way '1012' and 'ISIN' respectively. (I use a table better and after a CREATE statement for her but I have to rush right now, sorry).

declare
   k_sql_base        constant varchar2(500) := 'select description from attribute';

   t_names           constant varchar2_t := varchar2_t('attribute_id',  'name');
   t_values          constant varchar2_t := varchar2_t('1012',          'ISIN');

   l_sql             varchar2(500) := k_sql_base;
   l_rows_fetched    integer := 0;
   l_value           varchar2(4000);

   l_cursor_handle   integer;

begin
   -- Construct the SQL statement with column names and bind variables e.g.
   -- 'select description from mars.attribute where attribute_id = :b1 and name = :b2'
   for i in t_names.first .. t_names.last loop
      l_sql := l_sql ||
         case i
            when t_names.first then ' where ' else ' and '
         end ||
         t_names(i) || ' = :b' || i;
   end loop;

   dbms_output.put_line('SQL statment = ' || l_sql); 

   -- Parse the statement we built above (the remaining steps require a parsed cursor):
   l_cursor_handle := dbms_sql.open_cursor;
   dbms_sql.parse(l_cursor_handle, l_sql, dbms_sql.native);

   -- Associate the 1st column of output with variable l_value - required for SELECT statements:
   -- (actually the 3rd param here 'column' seems to be only used to get a datatype, in this case we want a string -
   -- dbms_sql.column_value actually extracts the value into a specified variable, which can be different.
   -- All examples in the documentation pass a local variable without further comment, so not entirely clear what this does other than set the output datatype.)
   dbms_sql.define_column(l_cursor_handle, 1, l_value, 4000);

   -- Now go through values array binding actual values to :bn variables in the cursor (similar to USING clause of EXECUTE IMMEDIATE)

      dbms_sql.bind_variable(l_cursor_handle, ':b'||i, t_values(i));
      dbms_output.put_line('Bound :b'||i || ' as ' || t_values(i));
   end loop;

   -- Open the cursor and fetch the result (no loop here because we are expecting a single-row result):
   l_rows_fetched := dbms_sql.execute_and_fetch(l_cursor_handle);

   -- 'Returns value of the cursor element for a given position in a cursor'
   -- Copy the value of column 1 to variable l_value (has to match
   -- dbms_sql.column_value(l_cursor_handle, 1, l_value);
