Dynamic Datamodel Query

I want to dynamicaly change my query in the datamodel based on certain conditions.
Can I accomplish this in the Before report or After parameter form report triggers ?
Basically, I want to substitute the query in the datamodel at runtime. The query will be such that it will
follow the datamodel relations as designed at compile time.
Any other suggestions would also help.
Thanks in advance.

Take a look at the on-line help under "lexical parameters".
Basically you can do the following:
User Parameter:
Name - P_SQL_STATEMENT
Default Value - select * from emp
Query:
Select Statement: &P_SQL_STATEMENT
At runtime, you can change the user parameter P_SQL_STATEMENT to any valid SQL statement that has the same number and type of columns that you created at design time. You need to set the default value so that Reports has something to default to during design time.

How to create a Type Object with Dynamic select query columns in a Function

Hi Every One,
I'm trying to figure out how to write a piplined function that executes a dynamic select query and construct a Type Object in order to assigned it to the pipe row.
I have tried by
SELECT a.DB_QUERY INTO actual_query FROM mytable a WHERE a.country_code = 'US';
c :=DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(c,actual_query,DBMS_SQL.NATIVE);
l_status := DBMS_SQL.EXECUTE(c);
DBMS_SQL.DESCRIBE_COLUMNS(c, col_cnt, rec_tab);
FOR j in 1..col_cnt LOOP
DBMS_SQL.DEFINE_COLUMN(c,j,v_val,2000);
END LOOP;
FOR j in 1..col_cnt LOOP
DBMS_SQL.COLUMN_VALUE(c,j,v_val);
END LOOP;
But got stuck, how to iterate the values and assign to a Type Object from the cursor. Can any one guide me how to do the process.
Thanks,

Hi Justin,
First of thanks for your reply, and coming to my requirement, I need to report the list of items which are there in the dynamic select statement what am getting from the DB. The select statement number of columns may vary in my example for different countries the select item columns count is different. For US its '15', for UK it may be 10 ...like so, and some of the column value might be a combination or calculation part of other table columns (The select query contains more than one table in the from clause).
In order to execute the dynamic select statement and return the result i choose to write a function which will parse the cursor for dynamic query and then iterate the values and construct a Type Object and append it to the pipe row.
Am relatively very new for these sort of things, welcome in case of any suggestions to make it simple (Instead of the function what i thought to work with) also a sample narrating the new procedure will be appreciated.
Thanks in Advance,
mallikj2.

Dynamic Select query is failing with error "Invalid Table Name"

OPEN rc FOR 'SELECT count(*) from :s' USING tab_name;
fetch rc into rec_count;
CLOSE rc;
my requirement is to build dynamic select query to retrieve the total count of rows in each table ( variable tab_name contains the table_name )
But I am getting stuck by this errror, not sure if there is any alternative !
ORA-00903: invalid table name
ORA-06512: at line 43

OPEN rc FOR 'SELECT count(*) from '||tab_name;
fetch rc into rec_count;
CLOSE rc;
-- This will work
1. Create a sql statement.
2. Open ref cursor for that statement.

Build dynamic SQL query in Database Adapter.

Hi All,
I have a requirement to build dynamic sql query at Database Adapter.
My BPEL process is getting search spec as input from siebel. I need to process this searchspec in BPEL and need to build the SQL query dynamically at Database Adapter to fetch the records from DB.
it goes like this....
1. Sieble Search Spec: city1 OR city2 OR city3 OR city4 .....
I need to build query as
select * from S_ADDR_PER where city like 'city1' OR city like 'city2' OR city like 'city3' OR city like 'city4' ......
2. Siebel Search spec: city1 AND country1 AND state1....
I need to build query as
Select * from S_ADDR_PER where city like 'city1' AND country like 'country1' AND state like 'state1' ....
3. Siebel Search spec: state
I need to build query as
select * from S_ADDR_PER where state like '%state%';
Is it feasible in Database Adapter? if its Yes.
Any guidelines to achieve this?
Thank you
Chandra

Setting Column Names in Dynamic Pivot Query

Hi all,
I'm having trouble setting column names in a dynamic pivot query and was wondering if someone could please help me figure out what I need to do.
To help you help me, I've setup an example scenario in my hosted account. Here's the login info for my hosted site at [http://apex.oracle.com]
Workspace: MYHOSTACCT
Username : DEVUSER1
Password : MYDEVACCTAnd, here is my test application info:
ID     : 42804
Name   : dynamic query test
Page   : 1
Table 1: PROJECT_LIST         (Alias = PL... Listing of Projects)
Table 2: FISCAL_YEAR          (Alias = FY... Lookup table for Fiscal Years)
Table 3: PROJECT_FY           (Alias = PF... Intersection table containing project fiscal years)
Table 4: PROJECT_FY_HEADCOUNT (Alias = PFH... Intersection table containing headcount per project and fiscal year)Please forgive the excessive normalization for this example, as I wanted to keep the table structure similar to my real application, which has much more going on.
In my sample, I have the "Select Criteria" region, where the user specifies the project and fiscal year range that he or she would like to report. Click the Search button, and the report returns the project headcount in a pivoted fashion for the fiscal year range specified.
I've got it working using a hard-coded query, which is displayed in the "Hardcoded Query" region. In this query, I basically return all years, and set conditions on each column which determines whether that column should be displayed or not based on the range selected by the user. While this works, it is not ideal, as there could be many more fiscal years to account for, and this is not very dynamic at all. Anytime a fiscal year is added to the FISCAL_YEAR table, I'd have to update this page.
So, after reading all of the OTN SQL pivot forums and "Ask Tom" pivot thread, I've been able to create a second region labeled "Dynamic Query" in which I've created a dynamic query to return the same results. This is a much more savvy solution and works great; however, the column names are generic in the report.
I had to set the query to parse at runtime since the column selection list is dynamic, which violates SQL rules. Can anyone please help me figure out how I can specify my column names in the dynamic query region to get the same column values I'm getting in the hardcoded region?
Please let me know if you need anymore information, and many thanks in advance!
Mark

Hi Tony,
Thanks so much for your response. I've had to study up on the dbms_sql package to understand your function... first time I've used it. I've fed my dynamic query to your function and see that it returns a colon delimited list of the column names; however, I think I need a little more schooling on how and where exactly to apply the function to actually set the column names in APEX.
From my test app, here is the code for my dynamic query. I've got it in a "PL/SQL function body returning sql query" region:
DECLARE
v_query      VARCHAR2(4000);
v_as         VARCHAR2(4);
v_range_from NUMBER;
v_range_to   NUMBER;
BEGIN
v_range_from := :P1_FY_FROM;
v_range_to   := :P1_FY_TO;
v_query      := 'SELECT ';
-- build the dynamic column selections by looping through the fiscal year range.
-- v_as is meant to specify the column name as (FY10, FY11, etc.), but it's not working.
FOR i IN v_range_from.. v_range_to LOOP
    v_as    := 'FY' || SUBSTR(i, 3, 4);
    v_query := v_query || 'MAX(DECODE(FY_NB,' || i || ',PFH_HEADCOUNT,0)) '
      || v_as || ',';
END LOOP;
-- add the rest of the query to the dynamic column selection
v_query := rtrim(v_query,',') || ' FROM ('
    || 'SELECT FY_NB, PFH_HEADCOUNT FROM ('
    || 'SELECT FY_ID, FY_NB FROM FISCAL_YEAR) A '
    || 'LEFT OUTER JOIN ('
    || 'SELECT FY_ID, PFH_HEADCOUNT '
    || 'FROM PROJECT_FY_HEADCOUNT '
    || 'JOIN PROJECT_FY USING (PF_ID) '
    || 'WHERE PL_ID = ' || :P1_PROJECT || ') B '
    || 'ON A.FY_ID = B.FY_ID)';
RETURN v_query;
END;I need to invoke GET_QUERY_COLS(v_query) somewhere to get the column names, but I'm not sure where I need to call it and how to actually set the column names after getting the returned colon-delimited list.
Can you (or anyone else) please help me get a little further? Once again, feel free to login to my host account to see it first hand.
Thanks again!

Dynamically built query on execution How to save the data in Object Type

Hi,
In pl/sql I am building and executing a query dynamically. How can I stored the output of the query in object type. I have defined the following object type and need to store the
output of the query in it. Here is the Object Type I have
CREATE OR REPLACE TYPE DEMO.FIRST_RECORDTYPE AS OBJECT(
pkid NUMBER,
pkname VARCHAR2(100);
pkcity VARCHAR2(100);
pkcounty VARCHAR2(100)
CREATE OR REPLACE TYPE DEMO.FIRST_RECORDTYPETAB AS TABLE OF FIRST_RECORDTYPE;Here is the query generated at runtime and is inside a LOOP
--I initialize my Object Type*
data := new FIRST_RECORDTYPETAB();
FOR some_cursor IN c_get_ids (username)
LOOP
x_context_count := x_context_count + 1;
-- here I build the query dynamically and the same query generated is
sql_query := 'SELECT pkid as pid ,pkname as pname,pkcity as pcity, pkcounty as pcounty FROM cities WHERE passed = <this value changes on every iteration of the cursor>'
-- and now I need to execute the above query but need to store the output
EXECUTE IMMEDIATE sql_query
INTO *<I need to save the out put in the Type I defined>*
END LOOP;
How can I save the output of the dynamically built query in the Object Type. As I am looping so the type can have several records.
Any help is appreciated.
Thanks

Flash chart with dynamic sql query does not display

Hi,
In my schema SIVOA I have a lot of tables declared like this :
CREATE TABLE "SIVOA"."EVV_xxxx"
   (     "CLEF_VAR" NUMBER(4,0),
     "DATE1" DATE,
     "VALEUR" NUMBER(16,8) Only the last part of the name changes "xxxx". For example E009, E019, etc....
I am making a chart page with report and want the user to select a name of a table and I will display using dynamic sql query, the table report and chart.
P184_ENAME is a select list returning the last part of the name of the table, fro example 'E009', 'E019', etc.
P8_CLEF_VAR is an item containing a value. This value is a key retrieved like this :SELECT CLEF_VAR
FROM SIVOA.SITE_ECHELLE
WHERE SITE = :P184_ENAMEI built a classic report using a sql dynamic function :DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = :p8_clef_var' ;
RETURN (x);
END;:p8_clef_var is an itme containing the value '4544'.
This works perfectly fine !
When I use this sql fucytion into a flash chart it does not work. I get this message "No data found".
I do not understand why a the report get a result and not the chart !
But if i hard-code the number of the CLEF_VAR instead of fetching it from :p8_clef_var I get a nice chart ! Go figure !DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = 4544 ' ;
RETURN (x);
I cannot stay with the key (CLEF_VAR) hard-coded unformtunately !
My question is how to get the chart displaying properly ??
Thank you for your kind answers.
Christian

Alex,
Using your request, with the classic report I get results (data), but I get the same message with the Flash chart : "No data found" ! I don't know how to investigate this. i tried many things but nothing works.
Christian
PS I tried this :
DECLARE
   X   VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, ROUND(VALEUR,2) FROM SIVOA.EVV_'
      || UPPER (:p184_ename) ||
      ' WHERE CLEF_VAR = '
      || :p8_clef_var ||
      ' AND DATE1 BETWEEN TO_DATE ('''
||:P8_DATE_DEBUT||''', ''DD/MM/YYYY HH24:MI'') AND TO_DATE ('''
||:P8_DATE_FIN||''', ''DD/MM/YYYY HH24:MI'')'
RETURN (X);
END; But it does not work either. I could find that the SLQ syntax generated is good becaus I put it into an item which display the return done by the pls/sql.
What is sttange also with the classic report is that if I do click on next or previous to see another rows, I get the message "No data found". If I try to export the report I get an excel file with "No data fouid".
Does anybody already tried my "need" here ? i find strange thant I should not be the firs one trying to get a report an tables which name would be "dynamic".
Tahnk you.

Absolute dynamic select query with dynamic join and where

Has anyone ever tried creating an absolutely dynamic SELECT query with dynamic Join and Where conditions.
I have a requirement of creating such a query in an Utility Class, and i have written the code. But its throwing my sysntax errors.
Please let me know where am I going wrong OR is it really possible to create such a dynamic Query??
    SELECT (FIELDS) INTO TABLE IT_TABLES
      FROM ( (ME->TABLE1) inner join ( me->table2 )
      on ( on_condition ) )
      WHERE (me->where_fields).
Ags.

It worked for me in a following way:
select * into corresponding fields of table <result_table>
        from (join_string)
        where (l_where).
Where the contents of join_string were dynamically build using concatenation. So it will be something like
concatenate ME->TABLE1 'as a INNER JOIN' me->table2 'as b ON (' into join_string separated by space.
<...>
add here matching/reference colums, something like
concatenate 'a~' me->TABLE1_JOIN_COL into temp1.
concatenate 'b~' me->TABLE2_JOIN_COL into temp2.
concatenate join_string temp1 '=' temp2 into join_string separated by space.
<...>
concatenate join_string ')' into join_string separated by space.
And then use similar approach for l_where variable.

How to use Field-symbol with dynamic select query

Can anybody tell me, how to use field-symbols in the dynamic select query.

FIELD-SYMBOLS <fs> { typing | STRUCTURE struc DEFAULT dobj }.
1. ... typing
2. ... STRUCTURE struc DEFAULT dobj
The FIELD-SYMBOLS statement declares a field symbol <fs>. The name conventions apply to the name fs. The angle brackets of the field symbols indicate the difference to data objects and are obligatory. You can declare field symbols in any procedure and in the global declaration section of an ABAP program, but not in the declaration section of a class or an interface. You can use a field symbol in any operand position in which it is visible and which match the typing defined using typing.
After its declaration, a field symbol is initial - that is, it does not reference a memory area. You have to assign a memory area to it (normally using the ASSIGN statement) before you can use it as an operand. Otherwise an exception will be triggered.
eg.
FIELD-SYMBOLS <fs> TYPE ANY.
DATA: BEGIN OF line,
        string1(10) VALUE '0123456789',
        string2(10) VALUE 'abcdefghij',
      END OF line.
WRITE / line-string1+5.
ASSIGN line-string1+5(*) TO <fs>.
WRITE / <fs>.
output:
56789

Best way to spool DYNAMIC SQL query to file from PL/SQL

Best way to spool DYNAMIC SQL query to file from PL/SQL [Package], not SqlPlus
I'm looking for suggestions on how to create an output file (fixed width and comma delimited) from a SELECT that is dynamically built. Basically, I've got some tables that are used to define the SELECT and to describe the output format. For instance, one table has the SELECT while another is used to defined the column "formats" (e.g., Column Order, Justification, FormatMask, Default value, min length, ...). The user has an app that they can use to customize the output...which leaving the gathering of the data untouched. I'm trying to keep this formatting and/or default logic out of the actual query. This lead me into a problem.
Example query :
SELECT CONTRACT_ID,PV_ID,START_DATE
FROM CONTRACT
WHERE CONTRACT_ID = <<value>>Customization Table:
CONTRACT_ID : 2,Numeric,Right
PV_ID : 1,Numeric,Mask(0000)
START_DATE : 3,Date,Mask(mm/dd/yyyy)The first value is the kicker (ColumnOrder) as well as the fact that the number of columns is dynamic. Technically, if I could use SqlPlus...then I could just use SPOOL. However, I'm not.
So basically, I'm trying to build a generic routine that can take a SQL string execute the SELECT and map the output using data from another table to a file.
Any suggestions?
Thanks,
Jason

You could build the select statement within PL/SQL and open it using a cursor variable. You could write it to a file using the package 'UTL_FILE'. If you want to display the output using SQL*Plus, you could have an out parameter as a ref cursor.

Dynamic selection query

Hi,
I need to write a dynamic select query based on the user's selection.
On Selection screen select options provided of fields like Company code, Plant and Sales Organazation.
Now, I have find out how many tables having field company code(If User enters data in this field) from DD03L table. And, based on the data retrieved, how many entries does exists in those tables matching user criteria.
Same thing for Plant and Sales Organization.
Thanks in Advance.

Short Dump for Dynamic Select Query

Hello all,
I get a short dump for my dynamic select query at the end of the code. The error is "The types of operands "dbtab" and "itab" cannot be converted into one another."
My code looks like below.
FORM get_ccnum_2 USING    p_tabname TYPE dd03l-tabname.
DATA: p_table(30) TYPE c.
FIELD-SYMBOLS: <dyn_wa>,
                               <t> TYPE table.
DATA: it_fldcat    TYPE lvc_t_fcat.
TYPE-POOLS : abap.
DATA: it_details   TYPE abap_compdescr_tab,
        wa_details   TYPE abap_compdescr.
DATA: ref_descr    TYPE REF TO cl_abap_structdescr.
DATA: new_table    TYPE REF TO data,
        new_line     TYPE REF TO data,
        wa_it_fldcat TYPE lvc_s_fcat.
p_table = p_tabname.
ref_descr ?= cl_abap_typedescr=>describe_by_name( p_table ).
it_details[] = ref_descr->components[].
LOOP AT it_details INTO wa_details.
    CLEAR wa_it_fldcat.
    wa_it_fldcat-fieldname = wa_details-name .
    wa_it_fldcat-datatype = wa_details-type_kind.
    wa_it_fldcat-intlen    = wa_details-length.
    wa_it_fldcat-decimals = wa_details-decimals.
    APPEND wa_it_fldcat TO it_fldcat .

      SELECT * INTO TABLE <t>
               FROM     (p_table)
               WHERE    (tab_cond)

Hi,
I tried to execute the code using table BSEGC and it gave a short dump..
the actual exception that shows in ST22 IS ..UNICODE_TYPES_NOT_CONVERTIBLE..
I think there is something wrong in the internal table creation..
Instead of using the method cl_alv_table_create=>create_dynamic_table to create the dynamic table I used the following and it worked..
CREATE DATA new_table TYPE TABLE OF (p_table).
* Comment begin " Naren
* ref_descr ?= cl_abap_typedescr=>describe_by_name( p_table ).
* it_details[] = ref_descr->components[].
* LOOP AT it_details INTO wa_details.
*    CLEAR wa_it_fldcat.
*    wa_it_fldcat-fieldname = wa_details-name .
*    wa_it_fldcat-datatype = wa_details-type_kind.
*    wa_it_fldcat-intlen    = wa_details-length.
*    wa_it_fldcat-decimals = wa_details-decimals.
*    APPEND wa_it_fldcat TO it_fldcat .
* ENDLOOP.
* CALL METHOD cl_alv_table_create=>create_dynamic_table
*    EXPORTING
*      it_fieldcatalog = it_fldcat
*    IMPORTING
*      ep_table        = new_table.
* Comment End. " Naren
CREATE DATA new_table TYPE TABLE OF (p_table).   " New code by naren
Please Try this..
Thanks
