Dynamic Select query question

I have a select query which uses a session variable in the
where clause like so:
select employee_lastname
from employee
where employee_id IN (#session.ids#)
This runs fine if I have only 1 employee id in session.ids,
but if I have multiple (i.e. 22,26,49) it crashes. Do I need to do
some sort of list or string conversion on my session variable?
Thanks in advance!
Dave

I re-read my reply and it came off as if i didn't read your
(op) last post, sorry about that. I attempted to recreate your
effect (see code below) I did a 'quick' session on the output page;
<cfquery datasource="#DSN#" name="test">
select busName, ID
from Hernandomembers
</cfquery>
<body>
<form id="form1" name="form1" method="post"
action="delme.cfm">
<label>
<select name="list" id="select" multiple="multiple">
<cfoutput query="test">
<option value="#ID#">#busName#</option>
</cfoutput>
</select>
</label>
<label>
<input type="submit" name="button" id="button"
value="Submit" />
</label>
</form>
Collects the selections of members from my DB and sends it to
a page with ....
<cfset SESSION.employee_ids=StructNew()>
<cfset SESSION.employee_ids="#form.list#">
<cfoutput>#SESSION.employee_ids#<br />
</cfoutput>
<cfquery datasource="#DSN#" name="test">
select busName,ID
from Hernandomembers
where ID IN(#SESSION.employee_ids#)
</cfquery>
<cfoutput query="test">
#ID# - #busName#<br />
</cfoutput>
And it works just as yours should.. So i guess I'd still like
to see how your getting the selections into the session, if not the
same way as me.

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,
mallikj2

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.

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
56789

The above given logic of mine works for you, put the code in the If condition and try-
just like below:
IF NOT P_EBELN IS INITIAL.
lt_where = '& = ''&'' '.
REPLACE '&' WITH p_ebeln INTO lt_where.
REPLACE '&' WITH field_value INTO lt_where.
SELECT (lt_sel_list) INTO CORRESPONDING FIELDS OF TABLE <lt_outtab>
FROM (p_tabnam)
WHERE (lt_where).

Dynamic Select Query including Dynamic Tables with For all Entries

Hello everyone,
I need to create a select query which involves using of Dynamic Tables.
Suppose I have a dynamic table <d1> which consist of let say 10 records.
Now i need to make a select query putting data into another dynamic table <d2>
CONCATENATE keyfield '=' '<d1>' INTO g_condition SEPARATED BY space.
CONCATENATE g_condition '-' keyfield INTO g_condition.
SELECT * FROM (wa_all_tables-name) INTO CORRESPONDING FIELDS OF TABLE <d1>
        FOR ALL ENTRIES IN <d1>
WHERE (g_condition).
But it is giving dump.
Please help me on this....

    A condition specified at runtime has an unexpected format.
What happened?
    Error in the ABAP Application Program
    The current ABAP program "ZNG_CUSTOMWRITE" had to be terminated because it has
    come across a statement that unfortunately cannot be executed.
Error analysis

How to build dynamic select query

Using the ZCO_SETTLE_CHK-REC_FIELD and DISTRIBUTION_RULE-KONTY write a dynamic select single query <table>-<field name> e.g. <COAS>- <AUART> on the <table> e.g. <COAS>. If the DISTRIBUTION_RULE-KONTY is u2018ORu2019, then use DISTRIBUTION_RULE-AUFNR value in the where clause of the query to fetch the ZCO_SETTLE_CHK-REC_FIELD value maintained in the <table>-<field name>. If DISTRIBUTION_RULE-KONTY = u2018KSu2019 or u2018PRu2019 use DISTRIBUTION_RULE-KOSTL or DISTRIBUTION_RULE- PS_PSP_PNR respectively in the where clause to fetch the values.
For above how we can build dynamic query

Hi,
Refer the below code which helps to design a dynamic where condition.
IF NOT p1 IS INITIAL.
CLEAR : lv_p1_condition.
CONCATENATE 'F1' ' = ' '''' p1 '''' INTO

ENDIF.
IF NOT p2 IS INITIAL.
CLEAR : lv_p2_condition.
CONCATENATE 'F2' ' = ' '''' p2 '''' INTO

ENDIF.
IF NOT p3 IS INITIAL.
CLEAR : lv_p3_condition.
CONCATENATE 'F3' ' = ' '''' p3 '''' INTO

Dynamic select query

Hi,
I am new to APEX. Trying to figure out how to implement a simple page that can take a select query defined by user at run time, for example, in a textbox, a user can type "select * from ***" (or any select statement) then hit submit. On the next page, he can get his result back if nothing with his select statement.
Second thing I don't know is version control. Since everything is stored in Oracle tables, how to you check the history of each file and compare between different versions?
Thank you so much for any help.

How to use dynamic select query which queries from 3 different table.

Hi All,
I am new to Toplink, i would like to use a named query to select some of the columns from 3 different tables with dynamic where clause.
I have used the following lines. Please tell me how to get code for the dynamic where clause.
First try :
Vector objPersons = (Vector)session.executeQuery("findPersonByGlobalID",Person.class,vQueryArguments);
The above method is not returning the vector or collection.
Second Try:
ReadAllQuery query = new ReadAllQuery(Person.class);
query.useCollectionClass(LinkedList.class);
LinkedList person = (LinkedList) session.executeQuery(query);
The second try is returning the collection but, this fetches all the record from the table.

Hi,
Did you try using a SQLCall ? It might be able to satisfy you requirements .. :-
Employee employee = (Employee) session.executeSelectingCall(
new SQLCall("SELECT * FROM EMPLOYEE WHERE EMP_ID = 44")
);You can get more information here :-

Dynamic select query for a dynamic table

Hi Guys,
i have a requirement where i have print the rows of a sql table which is passes dynamically. Let me walk you through the details of my requirement
i.e for example i have a procedure ABC which will print the rows of the table by taking the table name as parameter.
i have the below procedure, but its not printing the rows of the table
CREATE OR REPLACE PROCEDURE abc(tname varchar2) AS
BEGIN
execute immediate 'select * from '||tname;
end;
Your help is highly appreciated.
Regards,
Nagesh Manda.

So you want SQL*Plus to display the output? That's generally a bad idea, since the client application has to be explicitly set up to display output in the first place. If you have more than a small amount of data, you can also very easily exceed the buffer size.
What is the business purpose of this request? Whatever you're trying to accomplish, there's very likely a better option.
If you go down this path, you're going to need to use the DBMS_SQL package rather than native dynamic SQL. You could probably adapt some of the routines Tom Kyte uses to generate flat files.

Dynamic sql query question

hi all,
i created a report that displays results based on this query initially.
select *
from EMP
where 1=1;
i'm using a SQL Query (PL/SQL Function Body Returning SQL Query).
i have search items in my page like empno, lastname, firstname, middle, email_address etc... when i place a value for lastname then in my query it should add AND LASTNAME = :P1_LASTNAME.
so the query returned should now have
select *
from EMP
where 1=1
and LASTNAME = :P1_LASTNAME;
is this possible?
i was thinking something like looping for all search items in the page (ie. text, popup lov, datetimepicker) then check whether the item is null or not... when not null then probably get the substring of the item name like (ie. substr(:P1_LASTNAME) and get only LASTNAME then add "=" then concat it with the item name. not sure if this is possible though.
thanks
allen

hi denes,
thanks for the sample... i noticed that the sample hard codes additional conditions to be added to the sql query which is okay when the search criteria is less than 5-10... but i'm thinking if the search criteria will be like 15-30 fields or make all fields searchable, this might be uncomfortable.
what i was thinking is like loop thru all the items i.e.
declare
sql varchar2(4000) := 'select * from emp where 1=1';
begin
for i in (select * from all_items_in_apex) -- this is just an example.
loop
if i.value is not null then
sql := sql || ' and ' || i.column || '=' || i.value;
end if;
end loop;
end;
the only thing is that i don't know if there's a possible replacement for the clause (select * from all_items_in_apex).
sorry if i'm asking too much but this is how i normally do it in forms. the suggestion in the link you provided should be sufficient but i was just wondering if this idea is also possible.
thanks again.
allen
