Hi,
you could use Dynamic SQL /Execute immediate to run DDL from a stored procedure.

Could you please tell why do you want to create a materialized view in stored procedure ?
How frequently you will runt this procedure . It would is better to create a MV once and use it.

David,
In the current release, we do not support calling stored procedures from a
database control. You will have to write JDBC code in the JWS file to call
stored procedures.

You can use a database control to obtain a connection from any JDBC

could be connecting to any database, the database control is
independent

Oracle supports DATETIME data type.
"DATETIME" data type is stored in "DATE" data type.
if you want to DEFINE "10-Jan-1998 10:20" :
declare
dummy_date date:=to_date('10-jan-1998 10:00','DD-MON-YYYY

How to use optional prompts with stored procedure universe?

Hi Experts,
Iu2019m working on stored procedure universe in BO XI 3.0 SP2 FP2.5 with oracle at back end. My requirement is that I have to pass 5 optional prompts in the report and we have to pass these prompts through open document link. Please tell if this can be worked out on stored procedure universe?
Thanks in advance.

Hi,
Try with OpenDoc syntax as follows.
http://<servername>:<port>/OpenDocument/opendoc/<plat
formSpecific>?iDocID=****&sIDType=CUID&sType=wid/rpt&lsM/lsS/lsRPROMPTNAME=[V1],[V2]&sDocName=reportname&sRefresh=Y/N
where
server name: cms server name
port: portno
<platformspecific>=: for java -> openDocument.jsp
for .net -> opendocument.aspx
idocid,sDocName & cuid -> we can get report properties ( goto info view -> select report -> right click -> properties i.e. doc id, cuid and report name)
sType -> type of report i.e webi or deski ...
lsS -> to pass single prompt value
lsM -> to pass multiplle values to prompt
lsR -> range of values ....
Note: Here prompt name should be same as the one which we used in the report. Use + if there is blank space.
Cheers,
Suresh Aluri.

Hi, Mat,
Sorry, the answer is the same as it was in [your other thread|http://forums.oracle.com/forums/message.jspa?messageID=3610719#3610719].
You can't start SPOOLing insided PL/SQL.
Give the SPOOL command before you start PL/SQL, as Alex, Sundar and I showed you.
If you really do need to do file I/O from within PL/SQL, use util_file instead of dbms_output. With utl_file you can name, open, read, write and close files from PL/SQL. You can have several output files open at once, if you want to. See the [PL/SQL Packages and Types manual|http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28419/u_file.htm#BABGGEDF] for details.

How to use bind variables in this procedure

Hi Experts,
How to use bind variables in this procedure for static queries.
PROCEDURE DELETE_MER_PROC (M_id IN NUMBER)
IS
BEGIN
V_date DATE;
SELECT PD_DATE INTO v_date FROM PD_MAINTAIN;
    DELETE FROM MER_CLEAR
    WHERE MER_DT < v_date
    AND ID = M_ID;
COMMIT;
END;
How to use v_date and m_id as bind variables in this procedure to avoid hard parsing.
Please help me.
Thanks.

You cannot avoid hard parsing - as the 1st time a SQL statement (like the SELECT or DELETE statements in your code) is encountered, it does not reside in the server's Shared Pool, and needs to be added into the pool via a hard parse.
Bind variables does not prevent hard parsing. Hard parsing happens when the SQL statement (with or without bind variables) is a brand new statement encountered by the server.
Bind variables enables the same SQL cursor to be reused, by simply changing the bind variable value.
Not using bind variables means that each SQL statement is unique and not shareable - as the value is hardcoded into the statement and cannot be changed via a bind value. This typically means LOTS of different SQL statements (where the only difference is the changed value in the statement) are created - with each statement being a new statement not seen before in the Shared Pool and needing to be hard parsed.
One does not design one's code not to be hard parsed. There ALWAYS will be a hard parse in order to get a SQL statement into the Shared Pool. One designs one's code to REUSE cursors in the Shared Pool.

Using VIEW inside a stored procedure

Hi,
So I have a View designed in one file that validates someone who is authorized.
Then I have a stored procedure to display authorized stationeries created before a given date. Its takes a parameter @CreatedOn.
How can I use VIEW in my stored procedure so I can display all the authorized which are set 1 before a given date?
My VIEW:
ALTER VIEW vw_AuthorizedStationeries AS
SELECT Authorized
FROM dbo.Stationeries
WHERE Authorized = 1
And my stored procedure:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)ASBEGINSELECTFROMENDGO
Thanks!

Try something like below, You need to replace CreatedDate column with appropriate date column in your table.
1. Alter the view to get the required date:
ALTER VIEW vw_AuthorizedStationeries AS
SELECT Authorized, CreatedDate
FROM dbo.Stationeries
WHERE Authorized = 1
2. Alter SP:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)
AS
BEGIN
SELECT Authorized
FROM vw_AuthorizedStationeries
WHERE CreatedDate <= @CreatedOn
END
GO
OR
You can pull required information directly from your table:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)
AS
BEGIN
SELECT Authorized
FROM dbo.Stationeries
WHERE CreatedDate <= @CreatedOn and Authorized = 1
END
GO

How to call a sql server stored procedure from oracle

Hi all,
Please anybody tell me how to call a sql server stored procedure from oracle.
I've made an hsodbc connection and i can do insert, update, fetch data in sql server from oracle. But calling SP gives error. when I tried an SP at oracle that has line like
"dbo"."CreateReceipt"@hsa
where CreateReceipt is the SP of sql server and hsa is the DSN, it gives the error that "dbo"."CreateReceipt" should be declared.
my database version is 10g
Please help me how can i call it... I need to pass some parameters too to the SP
thanking you

hi,
thank you for the response.
when i call the sp using DBMS_HS_PASSTHROUGH, without parameters it works successfully, but with parameters it gives the following error
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Generic Connectivity Using ODBC][Microsoft][ODBC SQL Server Driver]Invalid parameter number[Microsoft][ODBC SQL Server Driver]Invalid Descriptor Index (SQL State: S1093; SQL Code: 0)
my code is,
declare
c INTEGER;
nr INTEGER;
begin
c := DBMS_HS_PASSTHROUGH.OPEN_CURSOR@hsa;
DBMS_HS_PASSTHROUGH.PARSE@hsa(c, 'Create_Receipt(?,?)');
DBMS_HS_PASSTHROUGH.BIND_VARIABLE@hsa(c,1,'abc');
DBMS_HS_PASSTHROUGH.BIND_VARIABLE@hsa(c,2,'xyz');
nr:=DBMS_HS_PASSTHROUGH.EXECUTE_NON_QUERY@hsa(c);
DBMS_HS_PASSTHROUGH.CLOSE_CURSOR@hsa(c);
end;
Create_Receipt is the sp which requires two parameters.
please give me a solution
thanking you

Can rs.last() be used after calling the stored procedure?

Can rs.last() be used after calling the stored procedure? If yes what should be the CURSOR types?

Can rs.last() be used after calling the stored
procedure? If yes what should be the CURSOR types?That would depend on the driver/database.
And as I said in your other post it is far more efficient to count records by just returning a count rather than a complete collection regardless of how you get to the end.

Using Copy statement in Stored procedure

The following statement works in sqlplus session:
copy from comment/password@servername append amcomment_temp using
select * from amcomment
where commentid in(1,2,3,4)
I want to use this in a stored procedure. There is a long datatype in this table. The
procedure will not compile. Have tried execute immediate and compiler rejects this statement also.

'COPY' is a SQL*Plus command, not PL/SQL. This is why the PL/SQL compiler throws it out.

How to use order by within Group by clause

Hi All,
I need a help as to how should i use the Order by clause so that the data should be in order with respect to one column, and at the same time whole data is grouped by some other column...like
Select RaceNo,Venue,FP,BP from Race group by RaceNo
Here I want to order by FP in ascending order for each group. When i am using it , whole order is changing.
Can anybody suggest me how to use order by clause that would apply to each group of data.
Thanks .

order by clause should be used at the last in any query.......but in group by clause u can't use use that becoz u group according to column then no ordering is needed there......if u want to filter something then u can use having clause and later if u need to arrange then u can use order by clause.........
i hope this eg.l gives u some clarification....
e.g
select deptno,count(empno)
from dept
group by deptno
having count(empno) > 10
order by deptno

Using temporary tables in stored procedures

Suppose that I have created a temporary table in a stored procedure using an "EXECUTE IMMEDIATE" statement. When I compile the procedure, that table is not created yet, so the compiler says that the table does not exist.
What is the way of using temporary tables in stored procedures?

It's a good practice to avoid using DDL statements being executed from stored procedures. "Truncate Table" via dynamic SQL from stored procedure is a different story and is useful in DSS environments.
But if you insist on "creating" tables using Dynamic SQL from Stored Procedures then you must also embed your DML statements in Dynamic SQL to avoid compilation errors.
Example:
Create or Replace Procedure Proc_TestDynamicSQL is
Begin
Execute Immediate 'Create table myTable as select * from user_tables' ;
Execute Immediate 'Update myTable set table_name = ''Test'' ' ; --two single quotes before and after the string "Test"
End;
In this case, Oracle wouldn't care about the table references during compilation.

In SQLScript, how to use EXEC to call another procedure with parameters in procedure?

Hi experts,
In SQLScript, How to use EXEC to call another procedure with input and output parameters in procedure？thanks very much

Hi Sagar,
thank you! I generate another procedure with an input parameter and an output parameter in a procedure. Then i need to call the generated procedure using EXEC. Here is my code:
create procedure ftest1(out sum_num bigint)
as
begin
declare fa_output bigint;
declare v_sql_drop varchar(200);
declare v_sql varchar(500);
declare cursor c_cursor1 for select num from TABLE1;
--v_sql_drop := 'drop procedure fe';
--exec v_sql_drop;
v_sql := 'create procedure fe(in i_num bigint,out o_num bigint) as begin';
v_sql := :v_sql || ' o_num := :i_num * 2 + :i_num * :i_num;';
v_sql := :v_sql || ' end';
exec v_sql;
open c_cursor1;
for c_item as c_cursor1 do
exec 'call fe(c_item.num,o_num=>fa_output)';
if sum_num is null then
sum_num := fa_output;
else
sum_num := :sum_num + fa_output;
end if;
end for;
close c_cursor1;
end;
The underline code is using exec to call the generated procedure. But this method cannot work. Any suggestion? thanks again!
