Got error when use case statement in oracle stored procedure

Hi,
I have a query like:
select merchant_id,
case
when product_type='K' then 'Production'
when product_carrier='UC' THEN 'Shipping'
end the_type
from product_tbl
where merchant_id=10114
It works fine. But as soon as I put it into a stored procedure, I got error like:
Encountered the symbol "CASE" when expecting one of the following:
( - + mod null <an identifier>
Please help!

Oracle 8i doesn't support CASE into PL/SQL, so as Kamal said, create a view with the CASE, and use this view into your PL/SQL.
Nicolas.
And an example here :
Re: Execute Immediate doesnot work in 8i (8.1.7) and Ref Cursor not exec qu

Extraction SQL statement from oracle stored procedure stored in file

Hi,
I am newbie to oracle stored procedure. I need to extract the list of sqls present in oracle stored procedure. Besides that I also want to parse these sql statements to get the list of tables and columns used. Is there any tool which can help me in doing thats.
thanks,
govind

why don't check on user_dependencies table instead?
select referenced_name,referenced_type
from user_dependencies
where name='<your stored procedure name in upper case>'
and referenced_type = 'TABLE'HTH,

ADO memory leak when getting Recordset from an Oracle stored procedure?

I am programming in C++ (VC 6) and using ADO 2.7 to
access Oracle 9i database. My connection string looks
like this:
Provider=MSDAORA.1;Persist Security Info=True;User ID=scott;Password=tiger;Data Source=blahblah
I have Oracle stored procedure that returns data in a
REF CURSOR output parameter. Since the stored procedure
takes input parameters, I prepare a Command object with
Parameters initialized and attached to it. I use the
Recordset Open method to execute the call. This approach
works because I get correct data back from the call in
the Recordset, but the problem is when I do this in a
infinite loop and watch the process in Windows Taks
Manager, I see 4k or 8k memory delta all the time and
the Peak Memory Usage of the process keeping going up.
I hope someone knows something in this scenario and points
me to the right direction.
Thanks, please see the following code for specifics.

Whenever large numbers of BSTRs are allocated and freed quickly the process memory will continue to climb towards a stabalizing value. BSTRs are not freed until the system frees them. You can see this by making many calls allocating and freeing BSTRs, memory will climb, but when you stop for a while the gargage collection of the sys strings will take place. I've done much research to see that a server doing many queries very rapidly is not leaking memory, but out pacing the garbage collection, it will stabilize and when the process has some "rest time" the processes memory usage will decline.
In my research a suspected memory leak was not one.

Statement closed when using callable statements with oracle xe

hi all, i've got this problem with oracle express edition 10g. I am using also oc4j v10.1.2.0.2. When working with a normal oracle database it was working fine (i think the code was the same, it's some time since i last tried, but you can see the code is very simple).
So i just create a callable statement like this:
CallableStatement cs = con.prepareCall(sentencia.toString(), ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE, ResultSet.HOLD_CURSORS_OVER_COMMIT);
and then when trying to access the statement to register an out parameter like this
cs.registerOutParameter(1, parámetros[0].getTipo());
it gives this error:
java.sql.SQLException: Statement was closed
It's puzzling me because, as i said before, i think the same code was working ok with a normal oracle database.
Any idea what can it be?
cheers

Ah okay, sorry I've re-read your post.
I believe you need to create a clob object that encapsulates your xml file.
I've never done this but I would image it involves creating a class that implements the clob interface and passing an instantiation of this class to the callablestatement.
Let me know how you get on.

Compiler error when useing switch statements in an inner class

I have defined several constants in a class and want to use this constans also in an inner class.
All the constants are defined as private static final int.
All works fine except when useing the switch statement in the inner class. I get the compiler error ""constant expression required". If I change the definition from private static final to protected static final it works, but why?
What's the difference?
Look at an example:
public class Switchtest
   private static final int AA = 0;
   protected static final int BB = 1;
   private static int i = 0;
   public Switchtest()
      i = 0; // <- OK
      switch(i)
         case AA: break; //<- OK, funny no problem
         case BB: break; //<- OK
         default: break;
private class InnerClass
      public InnerClass()
         i = 0; // <- OK: is accessible
         if (AA == i) // <- OK: AA is seen by the inner class; i is also accessible
            i = AA + 1;
         switch(i)
            case AA: break; // <- STRANGE?! Fail: Constant expression required
            case BB: break; // <- OK
            default: break;
}Thank's a lot for an explanation.

Just a though:
Maybe some subclass of Switchtest could decalare its own variable AA that is not final, but it can not declare its own BB because it is visible from the superclass. Therefore the compiler can not know for sure that AA is final.

Corrupt data error when using Windows backup on Oracle

Our SAP servers include a SDLT internal tape drive that we use for doing a complete system backup. When using Windows Backup we get the following message in the backup log:
WARNING: Portions of "\oracle\T00\sapdata1\protd_2\PROTD.DATA2" cannot be read. The backed up data is corrupt or incomplete.
This file will not restore correctly.
This is occuring on a couple of different systems but the wierd thing is when this happens in occurs on one Oracle drive in one system and the other Oracle drive on another system i.e. the G: drive on our TST sysytem and the E: drive on another. The E: and G: drives contain the main Oracle datafiles.
Has anybody ever encounter something like this and what can I do about it?
Thanks;
Gale S.

Especially no backup tool would know about the
fact
that a Oracle block had been changed after it was
copied.
Now I have to contracdict
There are backup tools (e. g. OpenFile Manager from
Legato/EMC), that track the filesystem changes and
makes sure, the backups are consistent in sense of
filesystem blocks. We´re backing up some ORA
databases (non-SAP, 7.3.4 and 8.1.7) for ages now -
and I never saw this kind of corruptions.
Well, these Backup-Tools do perform copies I/O-Consistent. That's different than DB-Block-consistent in the first place. Anyhow due to the fact that the DBMS do have a syncronizing between I/Os and writing out the blocks this leads both to consistent blocks.
I just wonder, how the database would deal with such
"inconsistent" files. Given the fact, you start a
backup at filesystem block 0, the database is being
backed up and a transaction is committed and
something is written to block 100, 200 and 500. The
backup is on block 300. If you now restore the
database, it has the already commited block 500 in
the file but 100 and 200 are not yet written in the
database file. The redo will then find an already
commited transaction on 500. What magic will tell the
engine, that this is due to an online database
backup? I mean, if you set the tablespace to backup,
the engine "knows" the state - but if you just backup
the file, the engine is unaware of that... I´m just
curious how this is handled...
Well the trick here is: we tell the database before we plan to copy the data. When a ONLINE backup is done, the tablespaces are set into BACKUP mode. This changes two things for us:
1. The datafile headers of these tablespaces are not updated anymore although dirty blocks are still written out to these files. Since the control files that keep the SCN (system change number) are updated nevertheless, the database will know at recovery time that these files had been in online backup mode and do need recovery to become consistent again.
2. The UNDO-information is not only written out to the UNDO/ROLLBACK-Tablespace but additionally to the REDOLOGS. So, for the time where the tablespaces are in BACKUP mode, we have all information needed to make a block consistent again - regardless if a transaction had been commited or rolled back - in the redolog. So a full recovery of all changes is possible with
that.
That's basically the "magic" behind this.
If the copy of the datafile is done without this - well, then there's no magician in the world that would been able to get it consistent again. Online Backups with Oracle are only possible with BACKUP mode or RMAN (ok, and possible some 3rd party hacks...).

Received error when using Execute_Immediate proc in Oracle 8.0

Hi,
I was trying to use the execute_immediate proc (slightly
revised, for testing). When I run it with a 'Delete' statement
in it (or passed in), it works fine. But, when I use
an 'Update' or 'Insert' statement in it, I get the error below,
even though the proc compiled okay and it's in the database okay.
SQL> exec Exec_Immed;

I tried using both the SQL stmts below (one at a time), but got
the same error.
CREATE OR REPLACE PROCEDURE Exec_Immed /*(v_SQLStmt IN VARCHAR2)

The simplest way to do what you are doing is to use a SQL

file:

2 SET    ename = 'David'
3 WHERE empno = 40
4 /
0 rows updated.
SQL> Insert into softlookup
2    (softno,softname,updatedon,updatetype)
3 values (50,'VS7',sysdate,'A')
4 /
1 row created.
Or, if you want to do it from an anonymous pl/sql block:
SQL> BEGIN
2    Update emp
3    SET    ename = 'David'
4    WHERE empno = 40;
5    Insert into softlookup
6      (softno,softname,updatedon,updatetype)

Or, if you want to do it in a procedure:

If you want to use DBMS_SQL to do it, even though it is

Since you are using Oracle 8.0 and cannot use EXECUTE IMMEDIATE,
if you want to use some variation, which is also unnecessary,
then you can do something like I have shown below. Note that
the Exec_Immed procedure needs to be a procedure all by itself
and not be modified. Otherwise, you are defeating the purpose
of substituting it for EXECUTE IMMEDIATE and not having to
duplicate code. The idea of using the Exec_Immed is to only
create that procedure which contains all of the DBMS_SQL once,
then use the really simple code below that to execute SQL
statements from a pl/sql block. If you are going to modify it,
then you might as well use the DBMS_SQL method listed above. In
the version below, I have used the variable names and so forth
that you have substituted for the original, as much as possible:
SQL> CREATE OR REPLACE PROCEDURE Exec_Immed
2    (v_SQLStmt IN VARCHAR2)
3 IS
4    v_CursorID       INTEGER DEFAULT DBMS_SQL.OPEN_CURSOR;
5    v_RetRows        INTEGER;
6 BEGIN
7    DBMS_SQL.PARSE (v_CursorID, v_SQLStmt, DBMS_SQL.NATIVE);
8    v_RetRows := DBMS_SQL.EXECUTE (v_CursorID);
9    DBMS_SQL.CLOSE_CURSOR (v_CursorID);
10 END Exec_Immed;
11 /
Procedure created.
Then, to use your Exec_Immed procedure from an anonymous pl/sql
block:
SQL> BEGIN
2    Exec_Immed ('Update emp
3                 SET    ename = ''David''
4                 WHERE empno = 40');
5    Exec_Immed ('Insert into softlookup
6                   (softno,softname,updatedon,updatetype)
7                 values (50,''VS7'',sysdate,''A'')');
8 END;
9 /
PL/SQL procedure successfully completed.
Or, to call your Exec_Immed procedure from another procedure:
SQL> CREATE OR REPLACE PROCEDURE procedure_name
2 AS
3 BEGIN
4    Exec_Immed ('Update emp
5                 SET    ename = ''David''
6                 WHERE empno = 40');
7    Exec_Immed ('Insert into softlookup

10 END procedure_name;

I get the error message:

I think this is because on the 2nd and 3rd line I'm trying to do arithmetic on a column which is varchar2 which I know I cant do.
How do I write a query which says: if the row contains text then give score of 1?

I'm using oracle 11g.Here's one way:
SELECT       CASE

           THEN 0

FROM       national_rare_ecosystems
;Since you don't really care about the numeric value, don't use NUMBERs anywhere; stick with VARCHAR2s, such as '0'.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data.
Point out where the query above is getting the wrong results, and explain, using specific examples, how you get those results from the sample data in those palces.

I tried using both the SQL stmts below (one at a time), but got
the same error.

Hi,
I was trying to use the execute_immediate proc (slightly
revised, for testing). When I run it with a 'Delete' statement
in it (or passed in), it works fine. But, when I use
an 'Update' or 'Insert' statement in it, I get the error below,
even though the proc compiled okay and it's in the database okay.
SQL> exec Exec_Immed;
begin Exec_Immed; end;

Trying to get prior error when using deferred constaint on Oracle database

Hi Greg,
There is no direct way to retrieve a error as an original exception
is wrapped. Also, it's problematic to report constraint violations
in general as different DB vendors use different ways to report them.
You may try to correct problem by extracting text of the exception
and looking for certain string patterns using direct string parsing
or regexps.

I'm using an Oracle database which has deferred constraints enabled. I'musing
Weblogic 5.1 and Java. The problem is that the deferred constraints
don't
report
errors until a commit. This makes all errors report back to the java EJBcode
as error code 2091: Transaction Rolled Back. Both errors show up in theWeblogic
log file so there must be some way for my EJB to access it. How can I
get
the
error code of the actual cause?

Stange error when using dbms_metadata.get_ddl in PL/SQL procedure

Basic info:
Oracle 10.2.0.4.0 on linux.
I'm trying to extract ddl of indexes that I drop and recreate frequently during monthly loads and store it in a table.
This statement works on the command line:
insert into saved_indexes
select index_name,dbms_metadata.get_ddl('INDEX',index_name,owner_name)
from sys.all_indexes
where owner = owner_name
and table_name = table_name;
commit;
The table 'saved_indexes' is a two column table with a varchar2(40) and a CLOB.
When I use the following procedure, I get 'ORA-04044 procedure, function, package, or type is not allowed here -4044' every time.
PROCEDURE SAVE_INDEXES (v_table IN VARCHAR2, v_owner IN VARCHAR2) IS
v_errorcode number(8);
v_errortext varchar2(1000);
v_start_time date;
BEGIN
insert into saved_indexes
select index_name,dbms_metadata.get_ddl('INDEX',index_name,v_owner)
from sys.all_indexes
where owner = v_owner
and table_name = v_table;
commit;
EXCEPTION
WHEN others THEN
v_errorcode := sqlcode;
v_errortext := substr(sqlerrm, 1, 1000);
dbms_output.put_line(v_errortext || ' ' || v_errorcode);
END;
Alternatively I have tried it this way:
PROCEDURE SAVE_INDEXES (v_table IN VARCHAR2, v_owner IN VARCHAR2 ) IS
v_errorcode number(8);
v_errortext varchar2(1000);
v_index_ddl CLOB;
BEGIN
for x in (select index_name
from sys.all_indexes
where owner = v_owner
and table_name = v_table)
loop
select dbms_metadata.get_ddl('INDEX',x.index_name,v_owner) into v_index_ddl from dual;
insert into saved_indexes
values(v_table,v_index_ddl);
end loop;
commit;
EXCEPTION
WHEN others THEN
v_errorcode := sqlcode;
v_errortext := substr(sqlerrm, 1, 1000);
dbms_output.put_line(v_errortext || ' ' || v_errorcode);
END;
Always with the same result. I have poured over the documentation on this and have not found anything. All objects are in the same schema, so there is not an issues with invokers rights, or privileges.
Any suggestions would be helpful...

Case Statement in Oracle Query.

Hello Oracle Gurus,
I need suggestion on whether I should use Case statement in Oracle queries.
I have a sql statement which inserts the data by selecting data from other table. While selecting the data I have put a logic in the select statement for one column which is something like this and there are some more similar statements in the same query.
CASE
               WHEN (b.ACCOUNT = 'FIN' or b.ACCOUNT ='FIN ACC' or b.ACCOUNT like '%Global Eq%' or b.ACCOUNT like '%Flexible Bond%')
               THEN
                    'MTM'
                         WHEN (substr(a.CTC,-3)='MTM')
               THEN
                    'MTM'
                         WHEN (substr(a.CTC,-3)='AFS' or substr(a.CTC,-3)='HTM' OR substr(a.CTC,-3)='ACC' OR substr(a.CTC,-3)='HFI' )
               THEN
                    'ACC'
               ELSE
                              'OTH'
          END,
I wanted to get an suggestion about how much performance issue can I have due to this in my insert statement.
Let me know if you need any other information.All comments are really appreciated.

Hi,
It's depends on the joins how you have performed with source table, stats and existing of indexes. If the volume of data is high - in case of any performance issue - why can't you perform the required things of logical conditions of data and popualte in one cluster so - that you can fetch out the chunks of required information with better way and in support with indexes.
Let us know the ful query your working on

Not able to retrive the recordset from oracle stored procedure in VC++

Hi,
I am trying to retrieve the records from the reference cursor which is an out parameter for an oracle 9i store procedure in VC++ application. But it is giving the record count as -1 always. Meanwhile i am able to get the required output in VB application from the same oracle 9i store procedure .
Find the code below which i used.
Thanks,

It can be linked to internal conversion. In some case, the value of internal or extranal value is not the same.
When you run SE16 (or transaction N), you have in option mode the possibility to use the exit conversion or not.
