Dynamic where clause in SP
Hi experts,I use Oracle Database 10 g Enterprise Edition Release 10.2.0.3.0 - 64 bit
I have to write a MS which has dynamic where clouse this where to accept the form of the value of the parameter.
This is my SP and Eroor.
CREATE OR REPLACE
PACKAGE PKG_EW_PROJection_QUERY AS
PROCEDURE PR_PROJECTION_QUERY(PD_AS_OF_DATE IN DATE,
PV_MEMBER_CODE IN VARCHAR2,
PV_TYPE_LIST IN VARCHAR2, -- here i have different input paramater and depending on this my where where clouse will be change
-- so my input string look like('abd,cfd,fgh') if it abd then my where condition different and if cfd
-- then where condition different.
CUR_PROJECTION_OUT OUT SYS_REFCURSOR);
END PKG_EW_PROJection_QUERY;

CREATE OR REPLACE
PACKAGE BODY PKG_EW_PROJection_QUERY AS

IS
sql_stmt varchar2(1000);
BEGIN
IF PV_TYPE_LIST LIKE '%GRA-PRINCIPAL%' THEN
SQL_STMT := 'SELECT P.FIC_MIS_DATE, P.V_MEMBER_CODE, P.V_TXN_DESC, P.N_AMOUNT_LCY FROM FCT_PROJECTIONS P, DIM_TXN_DESC D';

end if;
OPEN CUR_PROJECTION_OUT FOR SQL_STMT;
END PR_PROJECTION_QUERY;
END PKG_EW_PROJection_QUERY;
and i got below error

can you please let me know where I hurt m.If you need more information please let me know.
Thank you
Ritesh.
You do not have anything in your example that requires dynamic sql.
Consider this:
declare
cursor my_cur (val1 varchar2, val2 number) is
select column1, column 2
from table1
where column1 = val1
and column2 = val2;
begin
if your_condition then
--process the cursor declared above
for cur_rec in my_cur ('ABC', 12)
loop
do something
end loop;
end if;
end;
In your example, you're just concatenate strings together, which could be managed with variables.

Need help with dynamic where clause.
Hello world. I'm kind of a novice with PL/SQL, so please be patient with me. I am building a web application using Weblogic Oracle 11 g and Oracle database.
To make a long story short, I need to generate the complex dynamic WHERE clause. I don't know what will be the name of the column or the operator of comparison or the value will be until the moment of execution.
I'm not 100% certain, but I think I need to use dynamic SQL statements. Unless there is a better way to do it.
I'm sure that using dynamic SQL opens me up to SQL injection attacks if I use simple string concatenation. I would like to use bind variable if possible.
In any case, it seems like trying to build a dynamic where clause does not seem to work as I want it would be...
bv1 := 'colA = 5 and colB >= 9'; query_str := 'SELECT * FROM view WHERE :bv1'; OPEN CUR FOR query_str USING bv1;
The code above pours out when I try to run it.
Is there a way to build dynamic where the provisions without the use of concatenation of simple string that leaves me open to attacks by SQL injection?
Thank you
Hello. I have read briefly upward on things, you suggested, but it seems a bit abstract for me since I was a novice.
Can you give us an explanation or an example of how to use it to accomplish what I need to do?
Do ypu really plan create a query with a WHERE clause that contains a predicate for all possible columns?
Variable bind offer performance when the same query is executed several times with different values for bind variables.
Select * from emp where empno =: v_empno
After the first run Oracle will always be this query in the library cache. The next running can use the version of the cache even if the bind value is different.
Select * from emp where empno =: v_empno;
Select * from emp where ename =: v_ename;
Select * from emp where sal =: v_sal;
Each one is a DIFFERENT query. Yes - each of them uses a variable binding, but queries are different.
So, if your username select EMPNO, an '=', and a value from the first query can be executed. But the next time that the user can select the ENAME column so that 'stored' first request may not be used given that the query does not match.
The third time your user selects SAL so none of the first two queries can be used in the library cache. The use of bind variables gives performance during the SAME QUERY is used multiple times with DIFFERENT values for the variable binding. Oracle is not to analyze the hard query everything simply because the VALUE is different.
So bind variables do not help you if most of the queries were completely DIFFERENT sets of predicates. And SYS_CONTEXT will not help either since that simply provides a way to define binds the values of the variables.
Just for the simple example above, there are at least SIX possible combinations of columns that could choose your user name: empno, ename, sal, empno ename, empno & sal, ename & sal

Dear all,
I have a problem in the dynamic where clause in the OPS.
I have a VO query as below:
SELECT desc, ccuid, containid, XXXTMP conainline
I'll put whereclause as below:
VO.setwhereclause ("containid '101' =" + "order by containline desc")
so the question is request forms as below:
SELECT desc, ccuid, containid, XXXTMP conainline
(where containid = '101' containline desc order) -query gives question, adding the command from the inside of the caliper
Ideally, order by clause should come outside of the Stirrup.
so, how do I do order by clause order side where clasue or how do I remove the stand before the where clause. So I need the query as below:
SELECT desc, ccuid, containid, XXXTMP conainline
(where containid = '101' containline desc order)
SELECT desc, ccuid, containid, conainline from XXXTMP where containid = '101' containline desc order
or
SELECT desc, ccuid, containid, XXXTMP conainline
(where containid = '101') order by containline desc
Thank you
Hello
Solution 1-
You can use "setOrderByClause (containline desc);" so that it will get out of Where clause.
Solution 2-
Instead of dynamically add Whereclause, you can bind the variable as below-
Query in VO-
SELECT desc, ccuid, containid, conainline from XXXTMP where containid =: 1 containline desc order
In VOImpl-
public void initQuery (String variable)
{
clearCache();
setMaxFetchSize(-1);
setWhereClause (null);
setWhereClauseParams (null);
setWhereClauseParam (0, variable);
executeQuery();
}
Vall of this VOImpl method, and pass the variable value. It will work according to your requirement.
Thank you

Very Urgent: Setting dynamic where clause for Popup list VO
Hello world
It is a very urgent requirement please help as soon as possible.
I have a custom page in iSupplier. I created two supplier site, number of PO fields.
Site of beg - choice of Message and PO number - Message LOV of entry
I have a named VO under xxisupplier.oracle.apps.pos.home.poplist.server for site begging and xxisupplier.oracle.apps.pos.home.lov.server for PO number.
I have joined these two VO AM homepage.
Now the question is
1. I want to restrict these VO vendor_id-based so I'll put dynamically where clause for these two VO of in my CO
VO SITE PROVIDER QUERY
SELECT POVs.vendor_site_code site, pov.vendor_id
OF po_vendors pov, povs po_vendor_sites_all
WHERE pov.vendor_id = povs.vendor_id
AND TRUNC (povs.inactive_date) IS NULL
PO NUMBER LOV QUERY VO
SELECT DISTINCT ai.invoice_num, ai.vendor_id, ai.invoice_date, poh.segment1
AI ap_invoices_all,.
help ap_invoice_distributions_all,
po_headers_all poh,
po_distributions_all pda,
Al ap_lookup_codes
WHERE aid.po_distribution_id = pda.po_distribution_id
AND ai.invoice_id = aid.invoice_id
AND poh.po_header_id = pda.po_header_id
AND ai.invoice_type_lookup_code = al.lookup_code
AND al.lookup_type = 'INVOICE TYPE'
I am creating where cluase as below in CO
If (vendor_id1! = null)
{
System.out.println ("vendor_id:" + vendor_id1);
OAViewObjectImpl vo = (OAViewObjectImpl) am.findViewObject ("PO_LOV_VO");
if(vo!=null)
{
vo.clearCache ();
VO. Reset();
System.out.println ("inside IN. VO:" + vendor_id1);
vo.setWhereClause (null);
vo.setWhereClause ("vendor_id =: 1");
vo.setWhereClauseParams (null);
vo.setWhereClauseParam(0,vendor_id1);
vo.setOrderByClause ("invoice_date DESC");
String INVQRY = vo.getQuery ();
System.out.println ("INVQRY:" + INVQRY);
vo.executeQuery ();
VO. First();
System.out.println ("after the query appear" + vo.getRowCount ());
}
OAViewObjectImpl sitevo1 = (OAViewObjectImpl) am.findViewObject ("SUPPLIER_SITE_VO1");
if(sitevo1!=null)
{
sitevo1.clearcache ();
sitevo1. Reset();
System.out.println ("Interior site:" + vendor_id1);
sitevo1.setWhereClause (null);
sitevo1.setWhereClause ("vendor_id =: 1");
sitevo1.setWhereClauseParams (null);
sitevo1.setWhereClauseParam(0,vendor_id1);
String SITEQRY = sitevo1.getQuery ();
System.out.println ("SITEQRY:" + SITEQRY);
sitevo1. ExecuteQuery();
sitevo1. First();
System.out.println ("after the query appear" + sitevo1.getRowCount ());
}
Here he works for the purchase order number but the where cluase does not work for Supplier Site. Please help as soon as possible.
2 and also if supplier site to return multiple values then this field should show as messagechoice. If it returns a single value, then it should be the style text message
How can I achieve this.
Thank you
CSKTry
vo.setWhereClause ("IN vendor_id (" + vendor_id_qry + ")" ");
vendor_id_qry is the query that retrieves the list of provider IDS. You don't need to put the vendor column id as whereClauseParam unless you want to have IN the clause in your query of VO and pass the list as 1,2,3 values to the parameter.
Thank you

Interactive report dynamic where clause
Hello!
Is it possible that a report interactive sql source can have a where clause clause that is built dynamically?
MarcMarc:
You could empty the record-ID set in a collection of the APEX.
Change the IR query to add a join for this collection. Something likeselect c1, c2,c3... from main_tab a, apex_collections b where b.name='RECORD_IDS' and a.pk_col=b.to_number(c001)
More about APEX collections can be found at

Dynamic where clause of user defined reports
Hello everyone,
Is there a way to make / calculate a where clause clause in a user defined report according to the value of some bind variables?
I am trying to remove where the terms of my application if the binding variable is not defined.
previously, I did something as
AND tab.column = nvl (: colum_bin, tab.column)
but there are problems in implementation plans.
StoneSure that you can not, but how about you to rewrite the NVL in
OR: colum_bin IS NULL
Hope that helps,

Dynamic WHERE Clause with multiple ORs
I need to build a dynamic SQL statement such as the clause WHERE looks / works as follows:
WHERE x LIKE '%1% ' OR LIKE '%2% ' x OR x LIKE '%3%...
I can do the above, no problem, but I wonder if there is a better way?
Thank you
Mark
Hi, Mark,.
You should not need dynamic SQL for that.
For example, if you are still interested in substrings of characters suingle, and you get entry as a unique string called str (e.g. '123' it which means you want to find the rows where x contains '1', '2' or 3'), so you could say:
...
WHERE (x REGEXP_LIKE
, '[' || str || ']'
)
I hope that answers your question.
If not, post a small example data (CREATE TABLE and INSERT statements), a few entries and also post the desired results of each input given the same data.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).See the FAQ forum: https://forums.oracle.com/message/9362002#9362002

Hello
I have a table named TEST_TAB that has three columns - COL1, COL2 and COL3.
COL3 PEUVENT having distinct values of 1,2 and 3.
I need select * from TEST_TAB following conditions.
If COL3 has values 1,2 and 3 and select * should return only the rows with COL3 = 1.
If COL3 has no values 1, then select * should return only the rows with COL3 = 2.
IF COL3 is either 1 or 2, then select * should return only the rows with COL3 = 3.
Is it possible to do in a SQL? I prefer a single SQL.
Thank you.
Sajeeva Lacotte.Something like
select * from TEST_TAB where ( COL3 = 1 or ( COL3 = 2 and not exists ( select null from TEST_TAB where col3 = 1 ) ) or ( COL3 = 3 and not exists ( select null from TEST_TAB where col3 in ( 1, 2 ) ) ) )

How to dynamically generate where clause in Linq
Hi all
Oracle DB: 11 gR 2
Oracle Client: 11.2.0.3.0 (ODP.NET)
Oracle Developer Tools for Visual Studio
VS 2010 (C#)
In a Windows Form, it must query the data based on the values in list dropdown listboxes, which the user selects.
Let's say two combox, one Department and one for salary
Department:
-1 all the
10 Department 1
20 Department 2
30 Department 3
Salary:
-1 all the
1 < 20000
2 20000 to 50000
3 50000 to 100000
4 > 100000
Here is the c# code to query data:
using (var myEDMctx = new HREntities())
{
var LINQrslt = from emp in myEDMctx.EMPLOYEES
Select emp;
}
The default values for the two combox should be everything.
How to write dynamic where clause for this LINQ?
Thanks in advance!That's what I do.
var query = from c in customers

Hi Experts,
I have a VO with query like select * ministries dept, emp where dept.dept_id = emp.dept_id group... by order of dept.dept_id employees
At runtime, I need to add where clause with (and in dept.dept_id (select dept_id from table2))
I tried to use the vo.setWhereClause () method. But it does not work
Is there another solution?
I use Jdeveloper 12.1.3
Thanks in advance.
There are various possible solutions for this. You can either use setQuery that defines the entire sql statement. However, you then need to delete where condition adding yourself too.
Or you use viewCriteria as explained in this blog http://www.ahsanscorner.com/content/2015-11-16-1942-simulating-sql-clause-adf-viewcriteria-api.
Another approach is described by this blog Jet binary: using bind variable for SQL statements with the paragraph who uses a SQL table to build the in clause.

dynamic logic in SQL WHERE clause based on the value of the ELEMENT
Hello
I have a report based on the following SQL query.
Thank youselect dept_no, dept_name, dept_loc from dept where dept_loc = :P1_DEPT_LOC // If P1_DEPT_LOC is not null, I want the WHERE clause and IF P1_DEPT_LOC is null, then I don't need the WHERE clause. // how can I build this logic in same SQL

Published by: Deepak_J on March 11, 2010 16:37where: P1_DEPT_LOC IS NULL or dept_loc =: P1_DEPT_LOC
If dept_loc is not null better would be

dynamic instruction in where clause?
Hi all
I am writing a procedure and the request will be different according to the input parameters.
I wonder how I can do this inside where clause? simplified example
Select *.
from tableA, tableB b
where a.id = b.id
/ * If input parameter = "abc" then * /.
and a.total = b
/ * If input parameter = "xyz" then * /.
and a.total! = b
I was thinking case statement, but from what I've read, it cannot be used in this situation
Thank youHello
This give a try.
not testedselect * from tableA a, tableB b where a.id = b.id and (a.total= case when :input_param='abc' then b.total end or a.total != case when :input_param='xyz' then b.total end)

Using a CASE statement in 'IN' where clause clause
Hello
I have a form that users see after they connect with a few items and they type or select values based on the element type. All reports in the application use these values of PAGE 1 in where clause to filter the lines.
One of these question is "Quarter". I have a group of radio buttons on the PAGE 1 on the P1_QTR point.
I need to provide users a way to take the last 4, last 3, last 2 or current quarter and I need to dynamically build a clause WHERE the interactive report based on the selection in the form.
I am trying to use the CASE as shown below and get the syntax error.
AND QTR to (when BOX: P1_QTR = 'CURRENT' then ("T4"))
When: P1_QTR = "LAST" then ("Q3")
When: P1_QTR = 'LAST TWO' then ('Q3, "Q4")
When: P1_QTR = 'LAST THREE' then ("Q2", "Q3,' T4 ')
another ("T1", "T2", "Q3,' T4 ')
END)
How can I achieve this?
Following a simple logic, try
and QTR to
(
Select 'T4' double where: P1_QTR <> 'LAST '.
Union of all the
Select 'Q3' to double where: P1_QTR <> "in PROCESS".
Union of all the
Select "Q2" double where: P1_QTR not in ('CURRENT', 'LAST', "LAST TWO")
Union of all the
Select "Q1" double where: P1_QTR not in ('CURRENT', 'LAST', 'LAST TWO', 'THREE LATEST')

Passing the value of the where clause with the page
Dear friends,
I have a requirement like when I select a selection list value I should pass this value to sql query where clause without submitting the page
ex I have a select like: P1_Dept guess I selects the value 10 in this
then I have a query select * from emp where deptno =: P1_Dept.
DB. ORACLE 11G
APEX 4.1.1.00.23
is this possible? can someone help me please in this topic
Thanks and greetings
Vballeda
Suppose we have the selection list with the name P1_DEPT and query for report
select * from emp where deptno = :P1_DEPT
We create dynamic Action on the evolution of the P1_DEPT point. We will need two real actions:
1-> set value action
Set the Type - > body of the PL/SQL function
The function of body - > return 1;
Page item to submit-> P1_DEPT
Change to delete-> Yes event
Selecttion Type-> trigger element
2. action-> Refresh
Selecttion Type-> region
Region-> your region of report
