How to name commands (SQL codes)
Hi Guys,
I use sql queries in crystal. They are inserted in commands (database expert --add command). But I dont know hoe to name these so they are meaningful data sets? System always provide me with names command_1 command_2 etc but these are meaningless.
Thanks
Sonny
HI
After inserting the commands, Go to Database expert(Database->DatabaseExpert) from menu or else right click and select database Expert in field explorer. u will find the list of commands which u have added in the right hand side panel.
Select the command which u want to rename. Press F2 and rename it..

How to use pl/sql code as ODI user defined function
Hi All,
i have a pl/sql code and i want to create ODI user defined function using this code .
please find the pl/sql code below:
============================
declare
v_no_of_duplicate_rec number := 0;
begin
select count(*)
into v_no_of_duplicate_rec
from ( select 1
from temp_pre_selections
group by svb_number, selection_id
having count(*) > 1);
if v_no_of_duplicate_rec = 0 then
return 'N';
else
return 'Y';
end if;
end if;
==========================
please help me how to achieve the same .
Thanks
Vinod2 ways:
a. implement logic in odi function directly: getCount, Oracle implementation:
select case count(1) when 0 then 'N' else 'Y' end
from hr.employees
when you use this function to refresh a variable, the refresh statement should only be getCount, you shoueld not write select getCount from dual, otherwise it will become
select select .... from ... from dual
b. if your logic is complex, I suggest to write function directly in your database, then call this function in your ODI function
eg:
CREATE OR REPLACE FUNCTION hr.test RETURN varchar2 IS
tmpVar NUMBER;
BEGIN
select count(1) into tmpVar from hr.employees;
if tmpVar=0 then
return 'N';
else
return 'Y';
end if;
END test;
then create a ODI function, Oracle implementation is
hr.test
in your variable refresh statement, you can write select getCount from dual
if you use the odi function in other locations expect for refreshing variable, the idea is similar -
How to trace pl/sql code version over time
Hi,
As there are many pl/sql developers in the office I work in, we're thinking about how to mantain the old versions of pl/sql code and, above all, to forbid two different programmes to work on the same code at the same time.
I've been told we could use Subversion (http://subversion.apache.org/) also for pl/sql
What do you generally use for this target? Do you use Subversion or what else?
Thanks in advance!Mark1970 wrote:

What do you generally use for this target? Do you use Subversion or what else?We use Subversion and have been for many years (used CVS prior to that).
PL/SQL code is no different than Java code, C/C++ code, or any other code. So why should using a version control system like Subversion be used any differently (or not work correctly) for PL/SQL code? -
Hi All,
I want to share our application code to third party. I don't want them to see our application PL/SQL Code.
I have tried wrapper utility provided by Oracle, however there are un-wrappers available.
Please Let me know the options available to hide my PL/SQL code.
Thanks in advance
MadhuAs Billy says, the only proper way is through legal means.
The next best thing is the wrap utility. Yes, people have produced unwrappers out there, but most companies don't have their own software developers (otherwise they're less likely to be buying code from you), so won't be unwrapping it anytime soon.
I've seen some 3rd party tools that try and obfuscate the code by turning all your variables and suchlike into meaningless names, making it hard for people to follow the code even if they can read it, so if you find a good one of those, and then wrap it as well, you're making it hard for people.
DBMS_CRYPTO, as suggested by the first response on this thread, isn't an option as that is for encrypting or hashing etc. of data, not of PL/SQL code... at least not if you want Oracle to be able to execute the code still. -

How to convert pl/sql code into java/j2ee
Hi,
We have a PL/SQL Oracle App server application that we will support if we can convert in j2ee/java. But when i did take a look at the code, these pl/sql contains all HTML and java code inside the stored procedures.
And iam looking to explore some tools and mechanisms that can convert these pl/sql in a JAVA application so that i can deploy this new app into my BEA81 environment.
Does any body has any idea:
a) How to convert from pl/sql > java ?
b) Any plugins or tools of BEA that can run these pl/sql (the way thay are currently...i.e w/o converting) in BEA 81 container ?
thanks, sangitathese pl/sql contains all HTML and java code insideJava or JavaScript. They are not the same. I wouldn't expect to see Java inside html, whereas JavaScript would be intermixed. On the other hand you might have a java stored proc (Oracle 9/10) which is generating HTML.
>
Does any body has any idea:Refactor.
I doubt it just has html and JavaScript/Java. So what you have is a mess that mixes several things that should have been seperate in the first place. -
How to access PL/SQL code using JDBC
Hi,
We have stored procedures written in PL/SQL. These stored procs take both IN and OUT parameters. The parameter types are both regular datatypes like NUMBER, VARCHAR etc. So far so good. I know how to handle these data types.
Some of the stored procs also use parameters that are defined as composite data types like %ROWTYPE or %RECORD. How would I set the values of these data types? Can I use the oracle extension - support for Oracle Objects to accomplish this. If so please let me know with an example. If not any other suggestions or help will be greatly appreciated.
Thanks
KarthikJDBC (and SQLJ) only support SQL types as stored procedure arguments, not PL/SQL types.
If your stored procedure uses a PL/SQL-only type, such as BOOLEAN, record types, or index-by tables, then you cannot call it from Java (or, for that matter, from other languages as well).
There is one exception: scalar index-by table arguments have been supported since JDBC 8.1.7 in the JDBC-OCI driver (refer to the JDBC manual for specifics).
One workaround is to create wrapper PL/SQL stored procedures that take SQL arguments and convert them to PL/SQL -and vice versa- and call the original PL/SQL stored procedures. For example, a record type could be exploded into individual arguments, or it could be converted into a SQL object type, index-by tables could be represented as SQL collection types, etc.
You can find a small example of this in the back of the JPublisher manual, where an example is given how to call a PL/SQL stored procedure that takes BOOLEAN arguments. -
for example below shows:
create table temp
order_type varchar2(30),
order_num number);
insert into temp values('apple',000001);
insert into temp values('banana',000002);
insert into temp values('chair',000003);
select *
from temp
where instr(order_type,decode(x,1,'a',2,'b',2,'c',order_type)) >0
if i let x equals 2 and i want to get b and c from above querying .
why above query could not get 'c' and only get 'b' if i give 2 to x ?
how to write above select clause ?
who can help me ?
thanks!Decode will return the first match;
SQL> select decode(2,1,'a',2,'b',2,'c')
from dual
D
b
1 row selected.This may help;
old: select *
from temp
where regexp_like(order_type, case to_number(&x)
when 1 then 'a'
when 2 then 'b|c'
end)
new: select *
from temp
where regexp_like(order_type, case to_number(2)
when 1 then 'a'
when 2 then 'b|c'
end)
ORDER_TYPE ORDER_NUM

How can i identify the environment name or database name in the PL/SQL code
Hi,
I am using UTL_FILE to genearate the files.,
My problem is, I have to design the common sql file , which can be executed in 2 diffrent environments ( Say QA & DEV ) , with no parameters. It has to identify the environment and based on the environment , it has to generate the concern files.,
The only change needs to be incorporated is , file names , which will change based on the environment.,
can nay one tell me , how can i identify the environment name or database name in the PL/SQL code ??
RajaIn this case, USEC_GI_DEV.NA.XXXNET.NET is a TNS alias. That alias exists only on the client machine. There is no way to access that information on the database server.
You would have to find something in the v$database or v$instance table that uniquely identifies the database (and you may need some help from the DBAs to do this because you need to ensure that the data element you choose is compatible with whatever refresh process(es) are used in your environment).
Now, if you are writing a stand-alone SQL*Plus script, SQL*Plus, as a client tool, does have access to the TNS alias in later versions. But that is a client-side determination, not a server-side determination.

How do I pass selected values from dynamic LOV to Command SQL in Oracle
My environment:
Crystal 11
Oracle 10
I've created and tuned a SQL script for a report. In the Database Expert, I've copied the SQL into a Command. I've modified the Command to create 3 parameters.
I need help with the following:
1) How do I create a dynamic, cascading LOV and associated prompt group for the three parameters defined in the Command?
2) How do I pass the user selected valueS from the prompt group into the Command SQL as limits applied to the query executed against the database?I have the same problem with same environment .
The main report is having a 2 level cascading dynamic parameters.
I created a sub report with a command as below.
*select * from (*
select DATUM,MSEC,CNT,B1_NAME,B2_NAME,B3_NAME,ELEM_NAME,INFO_NAME,m.INFOTYPE,V.NAME,rank()
over (partition by B1_NAME,B2_NAME,B3_NAME order by DATUM desc ,MSEC desc,CNT desc) currentRank
from MESSAGES m,INTYDE i,VANAME v
where DATUM <=SYSDATE and trim(B1_NAME)='{?B1Name}'
and trim(B2_NAME)='{?B2Name}'
and m.INFOTYPE=i.INFOTYPE
and i.VALUE_NAME_NUMBER = v.VALNUM) where currentRank=1
I needs to pass cmbination of B1Name and B2Name from main report. I created a formula like
formula=Join({?B1Name},{?B2Name}),'|'); But this is showing some error.
and How I will substitute this in my command . As I new to Crystal XI help expected. -
How to 100% Protect PL/SQL Code By Wrapped in Oracle Database 10g R2
Hello,
Is Possible to 100% Protect PL/SQL Code By Wrapped in Oracle 10g R2 ?
If it is not possible by wrap in oracle 10g R2,
Please, let me suggest, how i will be able to 100% protect PL/SQL code in Oracle Database 10g R2.
Because, I have lot of functions, procedures & package's in my project.
Which is running in field filed.
So, i have needed to protect 100%.
Also, will i convert to al functions, procedures & package's to .pll file ?
And .pll file to .plx file?
Is it possible to convert .plx file to .pll file ?
Please, let know any better solutions in this case....
Regards
MehediHello,
No, wrapping is not a 100% secure method. It could prevent your code from amateurs, but not from professional hackers. Look at the article http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/wrap.htm#BEHGBJAA
It says: "•Wrapping is not a secure method for hiding passwords or table names.
Wrapping a PL/SQL unit prevents most users from examining the source code, but might not stop all of them."

How to reference LEVEL in a TREE's SQL code
Is it possible to somehow reference LEVEL in a tree's sql code so that you can use a decode statement to selectively create links on specific levels only i.e. NOT on the root level?
e.g.
select "CHILD_ID" id,
"PARENT_ID" pid,
"NAME" name,
decode( LEVEL, 1, null,'f?p=' || :APP_ID || ':43:' || :APP_SESSION || '::::P43_CHILD_ID:' || CHILD_ID) link,
null a1,
null a2
from TREETABLE
order by name
one solution I've implemented is to create a DB function e.g.
create or replace function get_tree_level(v_child_id number) return number
is
v_level number(2);
begin
select level
into v_level
from TREETABLE
where child_id=v_child_id
start with child_id=1
connect by prior child_id= parent_id;
return v_level;
end;
and then use
decode( get_tree_level(child_id) 1, null,'f?p=' || :APP_ID || ':43:' || :APP_SESSION || '::::P43_CHILD_ID:' || CHILD_ID) link,
but this is too slow as I have quite a few records in the tree and takes too long to render

How to add URL to tree
The view my tree is build on is constructed out of 3 unions and 4 "selects" ( the first select creates the ROOT NODE where "1" is also used as a hard coded foreign key (Parent_id), in the company table.)
I just added a new column called tree_level to the query which is hard coded wrt its level on the hierarchy.
e.g.
CREATE OR REPLACE FORCE VIEW COMCONSTUTREE ("CHILD_ID", "PARENT_ID", "NAME","TREE_LEVEL") AS
select 1 as child_id,to_number(null) as parent_id ,'Company' as name,*1 as tree_level* from dual
UNION
select COM_ID, 1, COM_NAME,2
from company
UNION
select CON_ID,CON_COMPANY_ID, substr(con_name,instr(con_name,' ')+1) ||', '||substr(con_name,1,instr(con_name,' ')-1),3
from contact
UNION
select STU_ID,STU_CONTACT_ID, STU_LAST_NAME||', '||STU_FIRST_NAME ,4
from student;
the tree code now becomes
select "CHILD_ID" id,
"PARENT_ID" pid,
"NAME" name,
decode( tree_level,1, null,'f?p=' || :APP_ID || ':43:' || :APP_SESSION || ':TREE:::P43_CHILD_ID:' ||CHILD_ID) link,
null a1,
null a2
from COMCONSTUTREE"

How can one read a Excel File and Upload into Table using Pl/SQL Code.
How can one read a Excel File and Upload into Table using Pl/SQL Code.
1. Excel File is on My PC.
2. And I want to write a Stored Procedure or Package to do that.
3. DataBase is on Other Server. Client-Server Environment.
4. I am Using Toad or PlSql developer tool.If you would like to create a package/procedure in order to solve this problem consider using the UTL_FILE in built package, here are a few steps to get you going:
1. Get your DBA to create directory object in oracle using the following command:
create directory TEST_DIR as ‘directory_path’;
Note: This directory is on the server.
2. Grant read,write on directory directory_object_name to username;
You can find out the directory_object_name value from dba_directories view if you are using the system user account.
3. Logon as the user as mentioned above.
Sample code read plain text file code, you can modify this code to suit your need (i.e. read a csv file)
function getData(p_filename in varchar2,
p_filepath in varchar2
) RETURN VARCHAR2 is
input_file utl_file.file_type;
--declare a buffer to read text data
input_buffer varchar2(4000);
begin
--using the UTL_FILE in built package
input_file := utl_file.fopen(p_filepath, p_filename, 'R');
utl_file.get_line(input_file, input_buffer);
--debug
--dbms_output.put_line(input_buffer);
utl_file.fclose(input_file);
--return data
return input_buffer;
end;
Hope this helps.
