CallableStatement procedure / function
Hello
Could you do me now under questions.
(1) CallableStatement callableStatement = txn.createCallableStatement ("start xxx_procedure (: 1: 2);") End; ", OADBTransaction.default);
If there are 2 inputs and 1 output parameters, how can I re - write Callable statement above.
I saw some examples of code online that were below formats, not sure which format is correct.
CallableStatement cs = txn.createCallableStatement ("start: 1: = check_Approval_Status(:2,:3);") End; ", OADBTransaction.default); - 1 i / p & o/p 2
CallableStatement cs = getOADBTransaction () .createCallableStatement ("start xx_lkp_details_pkg.list_lkp(:1,:2,:3); End; ", OADBTransaction.DEFAULT); - 1 i / p and 2 o/p
2) If there are 2 parameters of input and 1 output
How should I write below set out.
try {}
callableStatement.registerOutParameter (?, Types.VARCHAR); -What value instead of ?, it's 1, 2, or 3
callableStatement.setString (?, "Inputparameter"); -What value instead of ?, it's 1, 2, or 3
callableStatement.setString (?, "Inputparameter"); -What value instead of ?, it's 1, 2, or 3
String outParamValue = null;
callableStatement.execute ();
outParamValue = callableStatement.getString (?); -What value instead of ?, it's 1, 2, or 3
callableStatement.close ();
}
Thank you
It seems that you have 2 parameters in your procedure. 1st is IN parameter and the 2nd is OUT parameter.
That's why you used the code in setting below
callableStatement.setString(1, "Inputvalue");
for the OUT parameter
callableStatement.registerOutParameter(2, Types.VARCHAR);
Now, in what is the number, you used for your setting Out?
The answer is 2.
If you use the same number "2" to get the value.
So you should use
outParamValue = callableStatement.getString(2);
Hope this is clear.
Short answer: use the same number that you use to link value.
See you soon

Difference of procedure &; function
Hi all
After citing some tutorials, I got to know that the difference between the procedure and the function is that the procedure may or may not return a value as the function must return a value to the calling program. Given below is my procedure. & He would compare the lower of the two numbers would be smaller than
create or replace procedure findmin
(
x in number,
there in numbers,
z series
)
is
Start
if(x<y) then
z: = x;
on the other
z: = y;
end if;
end;
declare
c number;
Start
findmin (23,45,c);
dbms_output.put_line (c);
end;
Here's my function even if it does the same thing.
create or replace function findmin_fun
(
x in number,
y number
)
Return number
is
number of z;
Start
if(x<y) then
z: = x;
on the other
z: = y;
end if;
Return z;
end;
declare
Start
dbms_output.put_line (findmin_fun (56,28));
end;
I would like to know under what are all the scenarios of the procedure and function would be used. And also I want to know could do dml as insert, update, and delete operations
If so, could you guys explain me with some examples to expose DML operations on functions
After citing some tutorials, I got to know the difference between the procedure & function is that the procedure may or may not return a value as the function must return a value to the calling program.
Not quite.
A procedure does NOT return a value - it can fill in the parameters OUT or INOUT but which is NOT considered to be "of return values.
A function ALWAYS returns a value that can be null. The only exception is if the function throws an exception.
My procedure is given below. It would be to compare the lower of the two numbers & would mean that smaller
Not quite - the procedure returns NO value. You use it to try to fill one OUT parameter, but it's NOT the same.
I would like to know under what are all the scenarios the procedure & function would be used.
Functions can be used in SQL; procedures cannot be used in SQL.
The functions return a value; procedures of does NOT return a value.
Use the functions when you need to return a value; Use the procedures when you do NOT need to return a value.
It is not possible to list 'all scenarios' for one or the other, because there may be ANY NUMBER of possible scenarios.
And also I want to know could do dml as insert operations, update & delete
What happened when you tried?
The best and fastest, to learn is to actually TRY THINGS. Don't be afraid to break the Oracle by actually writing code and tests of things yourself.
If so, could you guys explain me with some examples to expose DML operations on functions
The Oracle documentation have a LOT of examples of using functions and procedures and include the code of the example.
https://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/subprograms.htm#CHDBEJGF

Updated APEX collection error ORA-04044: procedure, function, package, type
Hi all
I am trying to update the APEX MEMBER of the COLLECTION and encounter errors:
1 error has occurred
ORA-06550: line 9, column 8: PL/SQL: ORA-04044: procedure, function, package or type is not allowed here ORA-06550: line 7, column 3: PL/SQL: statement ignored
The PLSQL code are as below
DECLARE
entire x;
v_date_started VARCHAR2 (255);
v_date_finished VARCHAR2 (255);
BEGIN
SELECT c.seq_id
X
OF APEX_COLLECTION c
WHERE collection_name = "PHASE_COLLECTION."
AND c001 =: P41_MPM_ID
and rownum = 1;
v_date_started: =: P41_DATE_STARTED;
v_date_finished: =: P41_DATE_FINISHED;

p_collection_name = > 'PHASE_COLLECTION '.
, p_seq = > x
, p_c004 = > v_date_started
, P_c005 = > v_date_finished
);
END;
The process will take place after SUBMIT and validation.
The code I used to add a colletion APEX will work perfectly and is as below
-Initialization Collection PHASE_COLLECTION
BEGIN
IF THIS ISN'T APEX_COLLECTION. COLLECTION_EXISTS('PHASE_COLLECTION') THEN
APEX_COLLECTION. CREATE_COLLECTION ('PHASE_COLLECTION');
ON THE OTHER
APEX_COLLECTION. TRUNCATE_COLLECTION ('PHASE_COLLECTION');
END IF;
-Add members to the COLLECTION PHASE of table PHASE_MEMBERSHIP
IF: P41_MPM_ENG_ID IS NOT NULL THEN
FOR x IN (SELECT mpm_id, mpm_eng_id, phase_number, date_started, date_finished, date_created
OF phase_membership
WHERE mpm_eng_id =: P41_MPM_ENG_ID
AND active = 1
ORDER BY date_created)
LOOP
APEX_COLLECTION. ADD_MEMBER
(p_collection_name = > 'PHASE_COLLECTION')
, p_c001 = > x.MPM_ID
, p_c002 = > x.MPM_ENG_ID
, p_c003 = > x.PHASE_NUMBER
, p_c004 = > x.DATE_STARTED
, p_c005 = > x.DATE_FINISHED

);
END LOOP;
END IF;
EXCEPTION
WHILE OTHERS THEN
Logger.Error (p_message_text = > SQLERRM)
, p_message_code = > SQLCODE
, p_stack_trace = > dbms_utility.format_error_backtrace
);
LIFT;
END;
What I tried to use APEX_COLLETION to check the overlap between the date_range.
The requirement is just to display a warning if the user adds a record to the new phase or update record of current phase may overlap between the order of phase together.
Table PHASE_MEMBERSHIP script is
CREATE TABLE 'PHASE_MEMBERSHIP '.
(
ACTIVATE THE "MPM_ID" NUMBER NOT NULL,
ACTIVATE THE "MPM_ENG_ID" NUMBER NOT NULL,
ACTIVATE THE "PHASE_NUMBER" NUMBER (2.0) NOT NULL,
"DATE_STARTED" DATE NOT NULL ACTIVATE.
DATE OF THE "DATE_FINISHED."
'NOTES' VARCHAR2 (2000 BYTE),
'DATE_CREATED' DATE NOT NULL ACTIVATE.
ACTIVATE THE 'CREATED_BY' VARCHAR2 (20 BYTE) NOT NULL,
NUMBER (2.0) 'ACTIVE' DEFAULT 1 ACTIVATE NOT NULL)
So, basically, I want to fill the documents associated with a particular to a collection of APEX called PHASE_COLLECTION MPM_ENG_ID.
Then when the user specify date_started and date_finished, it will update/insert the APEX collection first.
Then the rank based on audit collection date
http://www.Oracle-base.com/articles/Misc/overlapping-date-ranges.php
then display the warning to ask the user to confirm message.
But then I'm stuck at the step of updating COLLECTION of APEX.
If anyone has any ideas on what is wrong, please help.
Thanks in advance.
AnnYour syntx error line number should give you the trick - it is not a member of the update, rather the SQL - you are referring to apex_collection, not apex_collections view dictionary.

Build a complicated procedure/function
Hello world
I am creating a complicated procedure.
I have three columns:
Column C contains a result. So, I need to find how this result was built. In other words, this procedure/function must answer the question:line A B C 1 5.5 3.2 - 2 1.05 6.1 - 3 0.6 7.8 - 4 6.4 4.13 - 5 - - 8.98
What are the numbers in columns A and B, which has contributed to achieve this result.
In this example, we found that:
(there is a condition: we cannot do so one number per line is selected.: A(1) + B(1).)C = B(1) + A(2) + A(3) + B(4) = 3.2 + 1.05 + 0.6 + 4.13 = 8.98

Your insert would be something like this:
INSERT INTO PR_OPS_APPOINT_SETS (SPEC_CODE1, SPEC_CODE2, CLINIC_NO, SECTOR_ID, USER_ID, APPOINT_DATE)
SELECT r.SPEC_CODE1, r.SPEC_CODE2, r.CLINIC_NO, r.SECTOR_ID, USER, d.APPOINT_DATE
PR_OPS_CLINIC_RECS r
CROSS JOIN)
SELECT TO_DATE (TO_CHAR (LEVEL - 1, "MM/DD/RRRR" + p_start_date), "MM/DD/RRRR") AS APPOINT_DATE
OF THE DOUBLE
CONNECT BY LEVEL<= p_end_date="" -="" p_start_date="" +="">=>
) d
WHERE SPEC_CODE1 = p_SPEC_CODE1
AND SPEC_CODE2 = p_SPEC_CODE2
AND CLINIC_NO = p_CLINIC_NO
AND SECTOR_ID = P_SECTOR_ID;
In terms of getting the parameters p_SPEC_CODE1, p_SPEC_CODE2, p_CLINIC_NO, P_SECTOR_ID...? I don't have enough information on your part.

Plan does not show the local procedures/functions
Hello
SQLD 4.1
I use the preview to a plsql procedure feature. The procedure provides a local procedure.
In the window structure the local procedure does not at all. Declared variables and cursors in the local procedure are displayed, but as if they where in the main proceedings.
Local procedures and functions should be displayed in the window structure. It would be nice if the declares the variables and cursors of a local proceeding would be arranged in suchs a means, it is visible that they belong to this local procedure, perhaps using an indentation.

2. the user have create session, synonym to create, select any user of permission.and table have default tablespace DATA.
(a) if the user has create any synonym it will store in the tablespace DATA?
(b) if the user can able to select a table only or can see all notices and the level of database functions?

solution in OWB, procedure/function
I have different columns in different tables, with values 0 or 1.
In the tables in the target, a 0 is no. and 1 Yes.
What is the best way to implement this.
a function/procedure on the database using as a transformation in OWB or
is there a better solution in OWB.
Another question: will I maps the columns separately or is there a way to map all columns through the 1 design element (transformation? expression?)?You will have problems with route mapping plug-in for the re-use of expressions since each use is considered to be a set of independent lines. That would leave functions as the first choice. ODI, reusable expressions can be made using the user-defined functions, with the latter in the code is placed online.

This isn't a function name, it is just a literal string. Looks like it is the registration of the name of a program or procedure that took trapped in an error, but in the end, it is simply insert the literal "schedule_vehicle_cred_check" in the ERROR_PROGRAM column

Why is conversion of procedures &; functions due to lack of MySQL to Oracle?
Hi all
I'm trying to migrate a database from MySQL to Oracle using the Migration Workbench data in SQL Developer 1.5.4.
I ran both the quick Migration Wizard and the Manual Migration process as described in the documentation.
I get through the process very well, even if not everything is successfully migrated. Namely, stored procedures and functions of the database of third parties are not correctly migrated.
The following text is listed in the Migration log for each of the stored procedures and functions:
* "Limitation of the translation"procedure_audit requires a translation of the manual"met on the column of the stored procedure fse.procedure_audit line 0-0."
If I look at the 'converted' model the procedure has been created and is set to NULL. The procedure of 'captured the model' original is commented out in the body of the procedure in the "convert" template Does anyone have any ideas as to why it's a failure? And how do I fix it?
In addition, there seems to be a problem with the conversion of the index, particularly those that are 'MAJOR' indexes in MySQL not appear in models 'captured' or 'converted '.
In addition, the migration log provides the following:
* "Index 'customer_customer_id' on the 'customer' table ' has been ignored, because it is a duplicate of a constraint" * "
Looking at the index in the original third party database, it does appear that an index on that column on the respective table. The ides why this happens?
Here, any help would be immensely appreciated.
