Dynamic query variable

How can I have a variable inside the query variable?
someQuery.dynVar# to be defined as "some text some text #
url.someVar# some text"
ColdFusion seems to disregard the CFML code contained inside
the
query or
cffile[read] variables and outputs it with variable names
surrounded with #. When it's set with
<cfset> it's displayed as intended.
How can I force CF to process CFML inside query
variables?

This reminds me of the biggest issue that has been bothering
me for years. ColdFusion CANNOT do dynamic code evaluating. This is
one of PHP's (it still sucks big time as a web application
development language) greatest advantages over CF, although
evaluating dynamic pieces of code is almost just as slow as
including them from files, one by one. But still...
CF's evaluate() can only evaluate functions, variables, etc.
But not actual code, including tags, multiple statements, or
anything complex like that.
Actually, I'm not quite sure what you're trying to achieve
here. It sounds like you want to set _triggers_ for variables, so
that they would auto-update themselves as some other variables
changes. Sounds impossible.
Also, you're wrong when you say "it" works with
<cfset>. Try this:
<cfset var1 = "dang">
<cfset var2 = "ding#var1#****">
<cfset var1 = "">
<cfoutput>#var2#</cfoutput>
If this would work as you stated, you would get "dingdong".
But you won't, since you can't process code dynamically within a
variable in CF.
So, you're best off with something like like cflib's UDF,
which takes care of the parsing right when you need it.

Dynamic query variables

All,
You guys were amazing helpful the last time I had an issue, and this seems like a much simpler question. I'm trying to create a dynamic query, and I'm having trouble generating the proper string.
Here's a sample table
Table: EMP
ID fname lname
1 bob smith
2 jane doe
3 telly savalas
What I'm trying to do is something like this:
TYPE QUERY_TABLES IS
TABLE OF VARCHAR2(1000)
INDEX BY VARCHAR2(64);
PROCEDURE test(outTable OUT testpkg.test_type)IS /*the out var is a ref cursor*/
QLIST QUERY_TABLES;
BEGIN
QLIST('something') := 'SELECT ''MY NAME IS ''||fname||'' FROM EMP';
open outtable for
QLIST('something');
return;
End test;
My problem is that I am getting confused on the syntax for the QLIST('something').
If it was not a variable, it would be
SELECT 'MY NAME IS ' || fname FROM EMP;
I guessed and ended up with
'SELECT ''MY NAME IS ''||fname||'' FROM EMP';
But of course that returns "FROM keyword not found where expected" error.
Thanks for any help and guidance you can provide.
-james

Maybe this one will help you
declare
v_query varchar2(128);
v_column varchar2(30) := 'last_name';
v_str varchar2(64) := '''my name is '' ||';
begin
dbms_output.put_line(v_str);
v_query := 'select ' || v_str || v_column || ' from employees';
dbms_output.put_line(v_query);
end;

Dynamic filtering with BEx query variables in WebI 3.1

Hi experts.
Can anybody help me ?
1) I use BEx query variables in WebI 3.1 . But i can't understand how to order fields of selection screen in WebI reports
2) How can i use Dynamic filtering with BEx query variables in WebI 3.1 ?
It's need that list of second field on selection screen will be accoding to result of selection first field on selection screen and so on .
Need i use BEx user-exit variables ?
Thank you

Hi,
1) Variable sequence isn't respected in XI3.1 - and can't be modified in OLAP.unv (this enhancement exists in 4.0 )
2) Dynamic filtering? Yes, Exit routines are the best way to go for this.

Help on performance with dynamic query

Hi All,
We are using SQL Server 2008R2. In our one of report we are using Dynamic query and it is taking more time to retrieve the data. to retrieve 32 records it is taking 13-15 secs. In my observation in a table variable, created more than 60 columns. In
the SP called one more sp with insert statement.
Please let me know how i can improve performance of the SP.
I know that i have to provide the SP for observation but unfortunately I cannot provide the SP. Please guide me how i can achieve this .
I tried with temp tables by creating indexes on temp tables but i couldn't find improvement in performance.
Waiting for valuable replies.

First of all a "dynamic query" is not "a query" - it is a multitude of them. Some of them may be fast, others may be slow.
There is of course no way we can give specific suggestions without seeing the code, the table and index definitions etc.
We can only give the generic suggestions. As for the code, make sure that you are using parameterised SQL and you are not building a complete SQL string with parameters and all. If nothing else, this helps to make the code more readable and maintainable.
It also protects you against SQL injection. And it also helps to prevent performance issue due to implicit conversion.
You will need to look at the query plan to see where the bottlenecks may be. You should look at the actual query plan. Note that the thickness of the arrows are more relevant than the percentages you see; the percentages are only estimates, and estimates
are often off. Next step is to see if you can add indexes to alleviate the situation. You should also analyse if there are problems in the query, for instance indexed columns that are entangled in expression. If you are using views, make sure that you don't
have views built on top of views etc. This can often result a table appearing multiple times in a query, when one would be enough.

Text lines in the BW query variables screen

Hi gurus.
The bw users ask me to display some text lines in the BW query variables prompt.
The text lines are saved in a custom table.
The only idea that I've got is to use customer exit text variables and fill them in CMOD when I_step = 1.
I don't like this solution (I should have more the 10 text lines and so I have to mantain more than 10 Text variables) but I can't find any other solution.
Any new idea or solution?
Is there in Bex enviroment a functionality (that I don't know) for doing somenthing like this ?
Thanks fo any help.
S.

Hi,
to resolve it you should create all the prompts in the BW query. You are using a query with 2 parameters and then a dynamic list of values. the dynamic list of values can only work after you entered the other values.

Dynamic query in where clause while looping in an internal table.

Hi,
Had a small question : How can i make a dynamic query for the WHERE clause while looping at an internal table.
i want to implement a dynamic where clause query for the below example.
it_cfx_col is an internal table and wa_cfx_col is a work area for it_cfx_col
DATA :
i_cfx_col TYPE TABLE OF cfx_col,
wa_cfx_col LIKE LINE OF i_cfx_col.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
LOOP AT it_cfx_col INTO wa_cfx_col
WHERE CREATED_BY = l_name
AND SCENARIO = l_scenario.
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
Now i want to write a dynamic query for the where clause.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
l_where_clause = 'CREATED_BY = l_name'.
l_where_clause2 = 'AND SCENARIO = l_scenario'.
if l_scenario is not initial.
CONCATENATE l_where_clause l_where_clause2
INTO l_where_clause SEPARATED BY space.
endif.
LOOP AT i_cfx_col INTO wa_cfx_col
WHERE (l_where_clause).
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
when i compile this i get an error message as { Statement concluding with "...(l_where_clause)" ended unexpectedly}
Even i changed the initilization of the variable l_where_clause2 to [ l_where_clause2 = 'AND SCENARIO = l_scenario.'. ]
added the end of line demarkation ".", but still i got the same error message.
Is it a limtation in ABAP that i cannot write a dynamic query for the where clause while looping at an internal table?
Regards,
om

Hi savita,
there in no such 1 limitaion in abap for dynamic query .. i think the error meassge is only beacuse of your synatx delcartaion.
>> LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE (l_where_clause).
   count = count + 1.
some business logic implemented using the work     area    wa_cfx_col
   endloop.
afted delclarataion also , in the where statement you should specify both the field name and value bname
   LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE l_where_clause = 'CREATED_BY = l_name' .
   count = count + 1.
hope it helps.

Creation of Dynamic Date Variables to be used in WebI reports

What we are trying to achieve is to create 4 optional filters (Current Day, Current Week, Last Week, Last Month) on 4 different dates which will allow the users to use them in WebI reports.
When using an optional SAP Customer Exit variable in BEx and creating a Universe on top, the filter becomes mandatory (i.e. the whole Universe is filtered by the SAP Exit, irrespective of whether the filter is used in the WebI report). Even if the filter is flagged as optional at the Universe level, it still behaves as mandatory.
If each filter becomes mandatory then we'll have to create 16 different Universes (for each optional filter and date combination)! This is not feasible.
I've seen in other posts that MDX Statements are not currently supported for Universes base on BW and SAP Exit should be utilized.
So with the existing BO version, is it possible to create optional dynamic date variables or is that a product limitation?
We are on XI3.1 SP3 FP3.1
Thanks

Hi Adam,
In BEx, I would create this query very easily using the "Amount" key figure twice in my results and restricting each with a different SAP standard out-of-the-box delivered variable. For your reference, the variables in BEx are: 0FPER and 0FYTLFP.
If I expose these variables in my OLE DB for OLAP query, they are not transfered into the universe, but rather act as filters on the entire universe. I've seen in documentation that only "Ready for Input" variables can be transfered as options into the universe which is not something that I have seen mentioned in this thread.
>> In the BEx Query you have the option to either make the variable "ready for input" or not. The behavior is the same in Bex or in the Universe / Web Intelligence. "Ready for input" means the user can actually provide an input and without the flag the user can not provide an input. Yes those variables are supported in the Universe.
Why this is a problem: I can't create separate universes based on potential variable periods that users might want to see. Additionally, many financial reports require concurrent use of these measures in the same report. Also, in reality it's not 2 variables, but dozens.
>> Which is a decision you make already on the BEx query level. if you decide that the variable is not ready for input then the user can change the timeframe in BEx either.
Also, I don't have a good way to mimic the standard out-of-the-box functionality given with BEx in BO. If I custom create all my variables in the universe, how do I do a lookup from the system date to the fiscal calendar that is stored on the BW server? In other words, how does BO know which date belongs in which period? (the same would be true with factory calendars for a different functional area).
>> Variable are created in the BEx query and the Universe will leverage those.
If you want a dynamic date range then EXIT variable as part of the BEx query - ready for input or not - is the solution.
regards
Ingo Hilgefort
The only work around I can see is to require users to enter the current fiscal period and have the BO reports filter based off that user entered value. This is unfortunate as the entire purpose of SAP Exit variables is to avoid having to require user input at report time.

Dynamic Query Doubt

Hi,
I need to write a Dynamic Query to get the data from the table by using the Input date parameters.
LIke,
SELECT* from table where date_start between to_date('12-14-2004','mm-dd-yyyy') AND
to_date('12-15-2005','mm-dd-yyyy');
How can i write the above query in dynamic sql as i will get the two dates as input in my procedure
Help me in this

Or more preferably use bind variables with the
EXECUTE IMMEDIATE as, if the query will be called
many times, the bind variables will prevent hard
parsing of the statement each time (i.e. it will be
quicker to execute).blushadow,
Yes, the execute immediate using bind variables is better/faster than not using bind variables, but your first example outperforms your second one. This is due to the fact that execute immediate really closes all cursors, and in your first example the cursors are kept open (yes, even though you issue a CLOSE cur_test) in the PL/SQL cursor cache.

How to create a dynamic query in which I can vary number of parameters

I am writing a JDBC connector. I want to write a dynamic query in that. The query should be able to proceed variable number of parameters and also in the where clause the and/or/like parameters I want to place dynamically.
I can't write store procedures as we just have read only access to Database so I want to do it through query only.
Please help me out in doing that as I am not able to proceed further without it ...

Ref Cursor Using Dynamic Query

Hi,
I need to use the ref cursor to fetch result from dynamic query.
e.g.
Open ref_test_tbl for Select * from tbl1 where tbl1.field1= :1
and tbl1.field2 =:2 using i_v1,i_v2;
The thing is i_v1, i_v2 are dynamic.
i.e. using clause can include i_v3, i_v4 also.
How to include dynamic variables in the using clause.
thanks

> How to include dynamic variables in the using clause.
Cannot using a ref cursor.. (and anyone that post code that writes dynamic PL/SQL in order to achieve this, I will call an idiot).
What you should be using in PL/SQL is a DBMS_SQL cursor. This allows you to create a fully dynamic SQL statement with bind variables. E.g.
select * from tbl1 where col1 = :1
select * from tbl1 where col2 = :1 order by 2
select * from tbl1 where col3 between :0 and :1
Using this dynamically created SQL statement, you can parse it using DBMS_SQL, determine the number of bind variables, and bind each of these dynamically.
You can then execute the SQL and again, dynamically, determine just what the projection of the cursor is. How many columns are returned, their names, data types, precision and so on.
This is what APEX (see http://apex.oracle.com) use extensively in order to run SQLs and render these as reports - all dynamically.
DBMS_SQL is detailed in the [url http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_sql.htm#BABEDAHF]Oracle® Database PL/SQL Packages and Types Reference manual.

Certain parts in an SQL query like FROM tablename cannot be local variables. In such a case, dynamic SQL can be applied:

Query a stored procedure that exec's a dynamic query. Error Linked server indicates object has no columns

I have a stored procedure that dynamically creates a pivot query. The procedure works and returns the correct data. Now I have a requirement to show this data in reporting system that can only pull from a table or view. Since you can not
create a dynamic query in a view I tried to do a select from using openquery.
Example 'Select * from OpenQuery([MyServername], 'Exec Instance.Schema.StoredProcedure')
I get the error back "the linked server indicates the object has no columns". I assume this is because of the first select statement that is stuffing the variable with column names.
CODE FROM PROCEDURE
Alter PROCEDURE [dbo].[Procedure1]
AS
BEGIN
SET NOCOUNT ON
Declare @cols nvarchar(2000),
  @Tcols nvarchar(2000),
  @Sql nvarchar (max)
select @cols = stuff ((
      Select distinct '], ['+ModelName + ' ' + CombustorName
       from CombustorFuel cf
       join Model m on cf.modelid = m.modelid
       join Combustors cb on cf.CombustorID = cb.CombustorID
       where cf.CombustorID > 0
       for XML Path('')
      ),1,2,'')+']'
Set @Tcols = replace(@Cols, ']', '] int')
--Print @Tcols
--Print @Cols
Set @Sql = 'Select GasLiquid, FuelType, '+ @Cols +'
from
Select GasLiquid, FuelType, ModelName+ '' '' +CombustorName ModelCombustor, CombFuelStatus+''- ''+CombFuelNote CombFuelStatusNote
  from Frames f
  join Family fa on f.Frameid = fa.frameid
  join Model m on fa.FamilyID = m.FamilyID
  join CombustorFuel cf on m.Modelid = cf.modelid
  Join Combustors c on cf.CombustorId = c.CombustorID
  join FuelTypes ft on cf.FuelTypeID = ft.FuelTypeID
  where cf.CombustorFuelID > 0
    and CombustorName <> ''''
) up
Pivot
(max(CombFuelStatusNote) for ModelCombustor in ('+ @Cols +')) as pvt
order by FuelType'
exec (@Sql)

Then again, a good reporting tool should be able to do dynamic pivot on its own, because dynamic pivoting is a presentation feature.

Displaying and reading are two very different things.
#1) SSRS Needs a fixed field list on the input side to know what what to make available in the designer.
#2) SSRS cant read "exec (@Sql)" out of a proc, even if there is a fixed number of columns (at
least it can't use it to auto build the field list from the proc)
I use dynamic SQL in my report procs on a fairly regular basis and I've found it easiest to simply dump
the results of my dynamic sql into a temp table at the end of the procs and then select from the temp table.
Basically, Erland is correct. Stop trying to pivot in the query and let SSRS (or whatever reporting software you're using) handle it with a Martix.

Dynamic query in ABAP

Can we use dynamic query in ABAP?

1. Dynamic where clause
You can use an internal table to build a dynamic where clause:
data: where_tab(30) occurs 1 with header line,
         where_clause(30) type c.
Build the where clause. Will look like this when finished
WHERE ZAFSTMD02 = 'X' AND rbusa = '5145'
With a constant, result: ZAFSTMD01 = 'X'
concatenate 'ZAFSTMD' zcostcheck-zmaaned ' = ''X''' into where_clause.
Append to internal table where_tab
append where_clause to where_tab.
With a variable, result: AND rbusa = '5145'
concatenate 'AND rbusa = ' '''' i_tab-zgsber ''''
append where_clause to where_tab.
Select
select * from zcostfreq
     where (where_tab).
endselect.
Note that you can combine static and dynamic where clauses:
select * from zcostfreq
     where bukrs = '2021' AND
                              (where_tab).
endselect.
2. Using a dynamic table name
This report prints the number og entries in a table. The table name is
specified by a parameter.
data:
l_count type i.
parameters:
p_tab type tabname.
start-of-selection.
select count(*) from (p_tab) into l_count.
write: / 'Number of entries in table ', p_tab, l_count.
3. Dynamic retrieval and writing of data
In this example, data is retrieved from the table selected on the selection
screen, and the contents of the
table is written to the screen.
DATA:
Create variable that can contain referecene to any data
dataref TYPE REF TO data.
FIELD-SYMBOLS:
<row>         TYPE ANY,
<component>   TYPE ANY.
PARAMETERS:
p_tab TYPE tabname.
START-OF-SELECTION.
Create a workarea for the tabel selected on the selection screen
CREATE DATA dataref TYPE (p_tab).
The variable dataref cannot be accessed directly, so a field symbol is
used
ASSIGN dataref->* TO <row>.
SELECT *
    FROM (p_tab) UP TO 10 ROWS
    INTO <row>.
    NEW-LINE.
    DO.
    Write all the fields in the record
      ASSIGN COMPONENT sy-index
        OF STRUCTURE <row>
        TO <component>.
      IF sy-subrc <> 0.
        EXIT.
      ENDIF.
      WRITE <component>.
    ENDDO.
ENDSELECT.
4. Dynamic SELECT
TYPES:
BEGIN OF st_bseg,
    bukrs LIKE bseg-bukrs,
    belnr LIKE bseg-belnr,
    dmbtr LIKE bseg-dmbtr,
END OF st_bseg.
DATA:
sel_list   TYPE STANDARD TABLE OF edpline,
li_bseg    TYPE STANDARD TABLE OF st_bseg,
l_bseg     TYPE st_bseg.
START-OF-SELECTION.
APPEND 'bukrs belnr dmbtr' TO sel_list.
SELECT (sel_list)
    FROM bseg UP TO 100 ROWS
    INTO TABLE li_bseg.
LOOP AT li_bseg INTO l_bseg.
    WRITE : / l_bseg-bukrs, l_bseg-belnr, l_bseg-dmbtr.
ENDLOOP.

Display results from dynamic query created and executed inside procedure

Hi;
I have created this code:
CREATE OR REPLACE PROCEDURE RunDynamicQuery(Var1 IN VARCHAR2, Var2 IN VARCHAR2, VAR3 IN VARCHAR2) AS
-- Do something
-- That ends up with a variable holding a query.... (just an example)
MainQuery :='select sysdate from dual';
end RunDynamicQuery;
How can I run this procedure and see the result on the dymanic query generated inside it?
BEGIN
compare_tables_content('VAR1','VAR2','VAR3');
END;
Expected Output for this given example:
20-05-2009 11:04:44 ( the result of the dymanic query inside the procedure variable MainQuery :='select sysdate from dual';)
I tested with 'execute immediate':
CREATE OR REPLACE PROCEDURE RunDynamicQuery(Var1 IN VARCHAR2, Var2 IN VARCHAR2, filter IN VARCHAR2) AS
-- Do something
-- That ends up with a variable holding a query.... (just an example)
MainQuery :='select sysdate from dual';
execute immediate (MainQuery );
end RunDynamicQuery;
BEGIN
compare_tables_content('VAR1','VAR2','VAR3');
END;
Output:"Statement processed'' (no sysdate displayed ! )
Please consider that the collums in the query are always dynamic... PIPELINE Table would not work because I would need to define a container, example:
CREATE OR REPLACE TYPE emp_tabtype AS TABLE OF emp_type;
FUNCTION RunDynamicQuery (p_cursor IN sys_refcursor)
RETURN emp_tabtype PIPELINED
IS
emp_in emp%ROWTYPE;
BEGIN
LOOP
FETCH p_cursor
INTO emp_in;
EXIT WHEN p_cursor%NOTFOUND;
PIPE ROW (...)

That would be a nice solution, thanks :)
''For now'' I implemented like this:
My dynamic query now returns a single string ( select col1 || col2 || col3 from bla)
This way I don't have dynamic collumns issue, and from business side, this ''string'' format works for them.
This way I can use the pipelines to get the result out...
OPEN myCursor FOR MainQuery;
FETCH myCursor
INTO myRow;
WHILE (NOT myCursor%notFound) LOOP
PIPE ROW(myRow);
FETCH myCursor
INTO myRow;
END LOOP;
CLOSE myCursor;
