Dynamic query to drop apps schema

Hi,
We are having a test ERP instance and we are refreshing it with ERP PROD export data through import on ERP test instance.
Now we want to drop all Oracle apps schema only in our test instance and through Import they will get created again.
Is there some dyanmic query through which i can drop only all apps schema.
Please help it is urgent.
Your help is appreciated.
Regards,
Milan

Now we want to drop all Oracle apps schema only in our test instance and through Import they will get created again.
Is there some dyanmic query through which i can drop only all apps schema.You cannot drop apps schema only due to data/object dependencies, so there is no such a query as your approach is not supported.
The only supported way is to install a new fresh database (standalone database), and export all EBS schemas from any other instance and import it to this new database. Or, use Rapid Clone to duplicate your database.
Thanks,

Dynamic query with drop down lists

I have two select queries in my program.
The first query is to obtain and then display the list of
clients.
The second query I want to display only projects which are
linked to a specific client.
<cfquery name="getClient" datasource="#request.DSN#">
Select tblClients.ClientID, tblClients.ClientName
From tblClients
Order by tblClients.ClientName</cfquery>
<cfquery name="getProjects" datasource="#Request.DSN#">
Select tblprojects.ProjectID, tblProject.Project,
tblProject.ProjectID
From tblProject, tblClients
WHERE tblClients.ClientID = tblProject.ClientID AND
tblClients.ClientID = #getClient.ClientID# </cfquery>
I am displaying the first select box ok and it is populated
with the correct information.
The second select box is ot quite correct. It is only
displaying one record - the first record in the file.
<select name="Client">
<cfoutput query="getclient">
<option
value="#getclient.ClientID#">#getclient.ClientName#</option>
</cfoutput>
</select>
<select name="Project">
<cfoutput query="getProject">
<option
value="#getProject.ProjectID#">#getProject.Project#</option>
</cfoutput>
</select>
Any ideas on how to correct this would be greatly
appreciated.
Kind regards

In your second query you are using the variable
#getClient.ClientID#
Outside of a <cfloop query=""> or a <cfoutput
query=""> CF assumes you meant
: #getClient.ClientID[1]# (which is the first record of the
getClient Query.
If you are trying to pull up a list of projects that are for
the getClient list, then try this instead
<cfquery name="getProjects" datasource="#Request.DSN#">
Select tblprojects.ProjectID, tblProject.Project,
tblProject.ProjectID
From tblProject, tblClients
WHERE tblClients.ClientID = tblProject.ClientID AND
tblClients.ClientID IN (#valuelist(getClient.ClientID)#)
</cfquery>
Valuelist changes any 'column' from a query into a list.
Hope this helps

FOR XML to generate dynamic script to drop multiple tables

Log_Table has a column named Col1 where we have table names
Col1
TableA1
TableA2
TableA3
TableB1
TableC1
TableC2
Generate dynamic script to drop tables that are in Log_Table and starts with TableA.
Instead of using the loop, use For XML

Thanks Visakh16 [+1],
you are right there was typo mistake :-) I forgot the variable in the end, and Thanks Naomi [+1],
this is true and better to use quotename or just add brackets. Actually I will not choose this approach since we chould use schema as well. the DDL in the OP is not something that I will create probably.
In any case, here is the fixed query (current approach):
declare @SQLString NVARCHAR(MAX)
SELECT
@SQLString = (select
N'IF OBJECT_ID (N''' + CAST([Col1] AS VARCHAR(MAX)) + N''') IS NOT NULL drop table [' + CAST([Col1] AS VARCHAR(MAX)) + N']; '
FROM Log_Table
WHERE (Col1 like 'TableA%')
FOR XML PATH (''))
--print @SQLString
EXECUTE sp_executesql @SQLString

Plz let me know if anyone of you faced this issue.
Rgds,
Thiru

Hi,
there is no such table MTL_ONHAND_DISCREPANCY or synonym in Applications 11.5.10.2. Is that custom table created in your db?
After dropping this table from APPS schema 'Re-create grants and synonyms for APPS schema' went thru fine.Its correct
This table does not exist in INV schema in 11.5.10.2.
Could be possible that the consultant could have created this table in INV and APPS schema by mistake or whatever.Yes, with the same name, there might be table in APPS SCHEMA. When you run recreate grants and synonyms, adadmin tries to create synonym for that table in APPS schema. since there is object available with the same name in apps chema, you got that error.

How to create an LOV based on a dynamic query

Hi,
Can someone tell me how to query a dynamic query for LOV. On my base page I have a dropdown-box (that will show the table names for searching) and is dynamically populated based on users access e.g. if user A logs in he may see 5 values (these values are basically table names) in a drop down if user B logs in he may see 10 values. I also have two input fields one field a user can enter value and the other field is read only and a torch icon for LOV so the user can search and select values that are populated in the input fields on the base page.
How can I have my LOV that takes in a value selected in the dropdown and anyvalue entered in one of the input fields and search in the table selected in the dropdown box.
Basically my LOV should do a search on the table and some search value passed when clicking on the torch icon. So a user can select any table-name in the drop down and my LOV should do a search only on the selected table. Once on the LOV Popup want to have a search field there but it only searched on the table selected in the dropdown on the based page. And the selected value on the LOV Popup page gets populated in fields on the base page.
Any help is appreciated.
Thanks

Help! Inaccessible iterator when using dynamic query

Hi!
I have a problem retreiving results from a dynamic query into sqlj iterator.
I consulted the Oracle App Dev Guide and Oracle SQLJ Dev Guide and wrote the following code:
<PRE>
package pmServer;
#sql iterator LocIterator (int id, String name);
public class pmRISDImpl
public int GetLocations(...)
LocIterator locIt;
String q = "select ID, NAME from PMADM.LOCATIONS";
#sql
BEGIN
open :OUT locIt for :q;
END;
</PRE>
When I try to compile it using tools provided by JDeveloper ver 3.2.2.(Build 915) for JDK 1.2.2 I get error for #sql statement:
Inaccessible Java type for host item locIt (at position #1): pmServer.LocIterator
and warning:
Type pmServer.LocIterator of host item locIt (at position #1) is not permitted in JDBC. This will not be portable.
Althow the code is identcal to those demonstrated in Oracle document "Oracle8 i
SQLJ Developers Guide and Reference
Release 3 (8.1.7)
July 2000
Part No. A83723-01" pp 12-67 (PL/SQL in SQLJ for Dynamic SQLDynamicDemo.sqlj). There it looks like
<PRE>

// build up query as Java string
String query = "select ename, sal from emp " +
(((what_cond == null) | | (what_cond.equals(""))) ? "" :

"order by ename";
#sql {

:query;
-- can have USING clause here if needed
end;
while (empIter.next()) {
System.out.println("Employee " + empIter.ename() +
" has salary " + empIter.sal() );
empIter.close();
</PRE>
Please guide me what should I do to get it working.

In the CAST statement the SQLJ runtime must be able to produce an instance of you SQLJ iterator using Java reflection.
This necessitates that the iterator class must be accessible by public.
You have two options:
(1) Declare the iterator public. This requires that you put it in its own file LocIterator.sqlj:
#sql public iterator LocIterator (int id, String name);
(2) Declare the iterator as an inner class. In this case you want to make it public static (that is it does not require an instance of the outer class in scope). You might write the following.
package pmServer;
public class pmRISDImpl
#sql public static iterator LocIterator (int id, String name);
(3) If you are using Oracle 9i you have another option. You can embed dynamic SQL fragments directly in your SQLJ code and do not need to use the CAST:
public int GetLocations(...)
LocIterator locIt;
String q = "PMADM.LOCATIONS";
#sql locIt = { select ID, NAME from :{q} }; // Note new syntax :{q} for embedding SQL source code
}

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.

New Book / Kindle: Beginner Database Design & SQL Programming Using Microsoft SQL Server 2014
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.

Building a dynamic query

I have a need to build a truly dynamic query, that would be able to take online form input and create a query that would handle data requests like, How many employees earn less than #some salary, have a masters degree, and speak chinese. or show me all the employees in org A that are vets.
A true ad hoc query tool.
the back end is oracle 11g, the database contains about 8 or 9 tables all total there about 500 records that will be searched. we are running CF7.
I just started kicking this around today so I am open for Ideas. add filters in the where clause, i got that, start with 1=1 and use conditional statements to add filters as necessary. setting up the Select and From statements, need help there.
Since this is a small db, I thout about, but scrapped, making a super-view to query from.
your thoughts and suggestions would be greatly appreciated.
thanks
jb

What about something like this:
1) Determine what tables are going to be involved (visual GUI/drag & drop interface for the users?)
2) Have a table that defines the relationship between the other tables in your database - once the table selection is made by the user, you can query this table to determine what columns you are going to join on. Obviously this won't allow you complete customization but it would work for the scenarios you describe.
3) Use your database system properties to retrieve the field names from your included tables
4) Allow your users to add "filters" based on the fields retrieved in (3)
e.g. You could use an interface to allow users to add a filter, where you display a list of fields from your tables and allow them to apply a simple filter to them - keep it simple (=, !=, >, <)
for bonus points, you could limit the options based on the field type (checkboxes for bit fields, etc)
sanitize the user input - find a SQL-safe reg exp script to handle any unwanted characters (I'm looking at you apostrophe).
5) Don't try an support aggregates if you don't need to - users can load the results into excel and manipulate them to their hearts content.
6) Build your SQL using the selections made by the user. Import all records from your joined tables. Use the table from (2) to determine which fields they join on. and build your where clause using the filters the user created in steap (4). Again, be sure anything not explicitly set by the system is sanitized prior to making its way into the SQL.
7) Execute() your SQL inside a CF query. Expect pretty poor performance, since most SQL databases won't optimize a query plan from a dynamic SQL evaluation.
You could build this as a multi-step wizard in CF, but it would be pretty flashy as a jQuery/web service based application.

Sort problem on dynamic query !!

Hi,
I have a dynamic query written in pl/sql, when I check "Sort" for each field in Report Attribute, error message raised up as "ORA-01785: ORDER BY item must be the number of a SELECT-list expression".
If I do not check Sort, it works fine. In my apps I need all fields sorted by user, how to fix this problem?
My query as below:
declare
query varchar2(2000):='select';
s_class varchar2(1000);
cursor c1 is select * from demo_preference;
begin
for c1_val in c1 loop
if c1_val.login is not null then
query := query ||' ' || 'login' || ',';
end if;
if c1_val.id is not null then
query := query ||' ' || 'id' || ',';
end if;
end loop;
query := SUBSTR(query, 1, length(query)-1);
s_class := '(NVL(:P2_class, ''%'' || ''null%'') = ''%'' || ''null%'' OR
EXISTS (SELECT 1 FROM apex_collections WHERE collection_name = ''P2CLASSCOL'' AND c001 = class))';
query := query ||' ' || 'from ming.reg_report_view1 where'
|| ' ' || s_class;
return(query);
end;

Maybe the internally mapped column used when you clicked on sort is not shown in the report. Try using aliases when you construct the query string, it could help apex internally in identifying a column even if its order changes for a different user. After all the column order in the code is dynamic and I guess even the no of columns displayed might vary both of which could make sorting on a column identified with a number, invalid.
How about displaying the report query somewhere, so that you know what is the exact query being processed, it might give you better information about the problem.
If the problem persists, then use a collection that is fetched those record using the same query string and change the report to refer the collection and then set column sorting on. This way apex would get confused on what columns are being sorted and it would just sort on a c001..c050 column as though it was a string(yes problems with number columns sorting when you do this).
