Basic PL/SQL
Is there any way by which i could see the underlying script of a stored procedure?
You can also use
dba_procedures,
all_procedures ,
user_procedures
to have more details about the procedures.Why not go the whole hog and just post this link:

Hey I'm trying to get a working understanding of some of the basics behind SQL, I've composed a few questions that I think may help me with this. Anyone that can help me with any of them will greatly help me thanks.
1. How to create synonym for tables?
2. How to describe the structure of tables?
3. How to list the contents of tables?
4. How to create a table named with the same structure as another table?
5. How to copy rows with less than a certain criteria in value (e.g. Price<$5.00) into another table?
6. How to change the data type to e.g. NUMBER(6)?
7. How to add a new column named with data type e.g. VARCHAR2(10)?
8. How to change a specific field within a table (e.g. For ORDER_NUMBER 12489, change the C_NUMBER to 315)?
9. How to delete a specific row from a table?
10. How to declare a column as the primary key of a table and call it e.g. PK_something?
11. How to show certain columns when another column is less than a certain criteria in value (e.g. Price<$5.00)?
12. How to show certain columns with another column having a certain item class e.g. HW or AP?
13. How to list certain columns when another column e.g. price is between two values?
14. How to list certain columns when another column e.g. price is negative?
15. How to use the IN operator to find certain columns (e.g. first and last name of customers who are serviced by a certain ID)
16. How to find certain columns when one of the columns begins with a particular letter (e.g. A)
18. How to list the contents of the a table sorted in ascending order of item class and, within each item class, sorted in descending order of e.g. price?
19. How to do a count of column in a table?
20. How to sum a column and make rename is something?
21. How to do a count of a column in a table (without repeats e.g. if a certain number repeats more than once than to only count it once)?
22. How to use a subquery to find certain fields in columns when the another column’s fields values are greater than e.g. its average price?848290 wrote:

Anyone that can help me with any of them will greatly help me thanks.To use the terminology you have in those questions, you must already have a basic understanding of SQL, so you have exposed yourself as not being the author of such questions.
Please do not ask homework questions without having at least attempted to answer them yourself first and show where you're struggling. -
Misc Basic PL/SQL Application Design/Programming Questions 101 (101.1)
---****** background for all these questions is at bottom of this post:
Question 1:
I read a little on the in and out parameters and that IN is "by reference" and OUT and IN-OUT are by value. To me "by reference" means "pointer" as in C programming. So it seems to me that I could call a function with an IN parameter and NOT put it on the right side of an assignment statement. In other words, I'm calling my function
get_something(IN p_test1 varchar2) return varchar2;
from SP1 which has a variable named V_TEST1.
So.... can I do this? (method A):
get_something(V_TEST1);
or do I have to do this (method B):
V_TEST1 := get_something(V_TEST1);
Also, although this may muddy the thread (we'll see), it seems to me that IN, since its by reference, will always be more efficient. I will have many concurrent users using this program: should this affect my thinking on the above question?
-- ******* background *******
So Far:<< I've read and am reading all over the net, read and reading oracle books from oracle (have a full safari account), reading Feurstein's tome, have read the faq's here.
Situation Bottom Line:<< Have an enormous amount to do in a very little time. Lots riding on this. Any and all pointers will be appreciated. After we get to some undetermined point I can re-do this venture as a pl/sql faq and submit it for posting (y'alls call). Some questions may be hare brained just because I'm freaking out a little bit.
Situation (Long Version):<< Writing a pl/sql backend to MS Reporting Services front end. Just started doing pl/sql about 2 months ago. Took me forever to find out about ref-cursor as the pipe between oracle and all client applications. I have now created a package. I've been programming for 20 years in many languages, but brand new to pl/sql. However, pl/sql sql has freed me from myriad of limitations in MS RS's. My program is starting to get big (for me -- I do a lot in a little) pks is currently 900 lines with 15 functions so far. Currently SP (pls) is back up to 800 lines. I get stuff working in the sp then turn it into a function and move it to the package.
What does application do?:<<<< Back End for MS Reporting Services Web front end. It will be a very controlled "ad-hoc" (or the illusion of ad-hoc) web interface. All sql queries are built at run-time and executed via "open ref cusor for -- sql statement -- end;" data returned via OUT ref_cursor. Goal is to have almost 100% of functionality in a package. Calling SP will be minimalist. Reporting Services calls the SP, passes X number of parameters, and gets the ref_cursor back.
Oracle Version: 10.2 (moving to 11g in the next 3 months).Environment: Huge DW in a massively shared environment. Everything is locked down and requires a formal request. I had to have my authenticated for a couple dbms system packages just to starting simple pl/sql programs.Brad Bueche wrote:

So it seems to me that I could call a function with an IN parameter and NOT put it on the right side of an assignment statement. The IN parameter is not passing by reference. It is passing by value. This means variable/value of the caller used as parameter, is copied to the (pushed) stack of code unit called.
An OUT parameter means that the value is copied from the called unit's stack to the caller (and the current value of the caller's variable is overwritten).
To pass by reference, the NOCOPY clause need to be used. Note that is not an explicit compile instruction. The PL/SQL engine could very well decide to pass by value and not reference instead (depending on the data type used).
Note that the ref cursor data type and the LOB data types are already pointers. In which case these are not passed reference as they are already references.
The NOCOPY clause only make sense for large varchar2 variables (these can be up to 32KB in PL/SQL) and for collection/array data type variables.
As for optimising PL/SQL code - there are a number of approaches (and not just passing by reference). Deterministic functions can be defined. PL/SQL code can be written (as pipelined tables) to run in parallel using the default Oracle Parallel Query feature. PL/SQL can be manually parallelised. Context switches to the SQL engine can be minimised using bulk processing. Etc.
Much of the performance will however come down to 2 basic issues. How well the data structures being processed are designed. How well the code itself is modularised and written. -
First off, I have to say that the documentation (what little there is) for the pl/SQL XML parser is absolutely terrible. I've figured out the bulk of it through trial and error, and some examples, but I'm stuck on something very basic. How do I get the actual value from a node?<br>
How would I get "PROC_CODE_GUID5" from this node? <f>PROC_CODE_GUID_5</f>.<br> I try to use xmldom.getNodeValue(nodename), but it never returns any value.Frank,
I'm sorry you had to go through the pains of figuring it out. I have been working with XML for a year now and have created a great website to help newcomers get started without the pain. The website is www.webspedite.com/oracle. Let me know what you think.

tis is confusing somebody help please?? and gimme the link where can I find docs to clarify these doubts.. explain about for loop for the same please...
I am starter in PL/SQL please help.....
Edited by: user12869307 on Apr 19, 2010 2:43 PMHi,
Please don't post unformatted code.
Indent line to show the extent of BEGIN, LOOP and similar statements.
Don't put too much on one line.
For example:
Declare
cursor curname is select *
from employees
where employee_id in (100,101);
v_emp curname%rowtype;
begin
open curname; -- this stage the query is executed and
-- datas are available in Active set which is
-- the area oracle allocated for this cursor
loop
fetch curname into v_emp;
exit when curname%notfound; -- first value is retrieved in the above
-- statement and the cursor is pointing to
-- second value in the active set..so this wil result no
-- bt for the next loop here cursor should nt point to
-- anything and this should exit Am i ryt? becaz there
-- are totally two values.. tis should exit witout printing wiout
-- doing the below print..
dbms_output.put_line ('name:' || v_emp.first_name);
end loop;
close curname;
end;
/Type these 6 characters:

I'm not sure I understand your comments. It would help if you posted the contents of your table, and the output you get, and asked a question specifically about those results, such as "Why do the results include ... ? Isn't the code supposed to ... because of ... in the data?"
If the query returns 2 rows, then FETCH will work 2 times with %FOUND = true. Only after the 3rd call to FETCH will %NOTFOUND become true. -
Hi,
I am new to Oracle world and I need some helps:
I need to run a lengthly ctx_ddl.sync_index procedure in our 10g R2 production environment, and I want to start the procedure at night and kill the session early in the morning next day.
I am having trouble in writing the PL/SQL procedure to kill the session that is running the sync index:
Here is my try:
CREATE OR REPLACE PROCEDURE KILL_SESSION
AS
MYSID INTEGER; //SID OF THE SESSION CALLING THIS PROCEDURE
KILLSID INTEGER; //SID OF THE SESSION THAT IS RUNNING THE SYNC INDEX
KILLSERIAL INTEGER; //SERIAL# OF THE SESSION THAT IS RUNNING THE SYNC INDEX
BEGIN
SELECT DISTINCT(SID) INTO MYSID FROM MY V$MYSTAT;
^ ^^^ V$MYSTAT COMPILATION ERROR - NO SUCH TABLE OR VIEW
SELECT SID INTO KILLSID, SERIAL# INTO KILLSERIAL FROM V$SESSION WHERE SID NOT IN (MYSID) AND OSUSER='SYS_ADMINISTRATOR';
^ ^^^ V$SESSION COMPILATION ERROR - NO SUCH TABLE OR VIEW
ALTER SYSTEM KILL SESSION 'KILLSID, KILLSERIAL';
^^^^^^^ CAN I USE VARIABLE NAME INSIDE A SINGLE QUOTE??????
END KILL_SESSION;
Any help is appreciated !Hi,
Welcome to the forum!
When you post code on this site, make sure it is formatted, and type these 6 characters
{code}
(small letters only, inside curly brackets) before and after formatted text, to preserve spacing.
When you post error messages, cut and paste the entire message. Somethimes, the message number and the line/cloumn number are helpful.
Vg is right: there's something fundamentally flawed with a job that you have to kill.
Can you sub-divide the job, and do a different part each night?
A KILL procedure is handy in any case. As Vg said, you (the procedure owner) have to have privileges granted directly to you. Roles don't count inside stored procedures, so merely having a role that lets you query the data dictionary views is not enough.
Also, you may need privileges granted on the actual V_$ views, rather than the V$ synonyms. (That is, V$MYSTAT, without an underscore, is just a public synonym for the view SYS.V_$MYSTAT, with an underscore in its name. You want to GRANT SELECT ON V_$MYSTAT to proc_owner;) -
Basic PL/SQL Question about running context
We are trying to create some generalized tools with PL/SQL procedures that would be used by a number of different Oracle Users/Schema. The idea was to store them in an administrative schema (call it ADMIN), create public synonyms for them, and grant execute to public. Then we could run them from the user schema (call it USER) to do the work.
It was my assumption, that while the procedures were stored in ADMIN, when they were run by USER they would run in the USER context. EG, a table (call it MYTABLE) that was referenced in the procedure without a schema reference (SELECT * FROM MYTABLE) would expect to find MYTABLE in the context of the schema which called the procedure. In other words, call the procedure from USER, I expected the procedure to look for MYTABLE in USER. However, we are getting errors that indicate that even though the procedure is called from USER, it is looking for the table in ADMIN (the procedures creation context), no in USER (the running context).
QUESTIONS: How is PL/SQL supposed to operate in this situation? Are there any options/parameters that can be set so the procedure will use the runtime context for table lookup, or do we have to write dynamic SQL which will fully qualify the table with the owner schema?
Thanks for your help
John ConroyHy,
from the manual:
The AUTHID clause is allowed only in the header of a stand-alone subprogram, a
package spec, or an object type spec. The header syntax is
-- stand-alone function
CREATE [OR REPLACE] FUNCTION [schema_name.]function_name
[(parameter_list)] RETURN datatype
[AUTHID {CURRENT_USER | DEFINER}] {IS | AS}
-- stand-alone procedure
CREATE [OR REPLACE] PROCEDURE [schema_name.]procedure_name
[(parameter_list)]
[AUTHID {CURRENT_USER | DEFINER}] {IS | AS}
-- package spec
CREATE [OR REPLACE] PACKAGE [schema_name.]package_name
[AUTHID {CURRENT_USER | DEFINER}] {IS | AS}
-- object type spec
CREATE [OR REPLACE] TYPE [schema_name.]object_type_name
[AUTHID {CURRENT_USER | DEFINER}] {IS | AS} OBJECT
where DEFINER is the default option. In a package or object type, the AUTHID
clause applies to all routines.
Note: Most supplied PL/SQL packages (such as DBMS_LOB, DBMS_PIPE, DBMS_
ROWID, DBMS_SQL, and UTL_REF) are invoker-rights packages. -
I'm a graduate student just learning to grasp PL/SQL. Does anyone have any links to suggested sample PL/SQL programs? I've been tasked to do some Oracle spatial intersection queries. I have most of the actual commands down but could use some help tieing them around the PL/SQL language.
Many thanks.Best place is the documentation ...
For pl/sql :
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14261/toc.htm
All the best for your baby-steps in pl/sql. -
Edit: I have updated the below to reflect that it took four hours for the database to unblock. This looks like a bug to me. SQL Server seemed to believe there were 30 running sessions with open requests nearly four hours after the client
side connections were terminated (and thus in the process blocking SQL Server from accepting new connections).
Problem
I am running a preview "Basic" edition SQL DB and have hit a problem with Azure SQL DB blocking database access for an extended time period.
I was running a test, which was running normally for several hours (loading small batches of data), then suddenly lots of connection timeouts (error type 1 below). My workload was constant over the whole test - but if the server was suddenly under
pressure, I accept this might happen - no problem with me so far.
Upon retrying, the errors then changed to request limit exceeded (error type 2 below).
I am surprised I hit the limit in the first place, since the test code closes the SQL Connection on a timeout error and reopens. (In C#, the code is wrapped in a using{} to ensure prompt connection closure). Still, perhaps the amount of concurrent
work on the server did momentarily hit this limit. Perhaps fair enough on this point too.
BUT: Surprisingly, nearly four hours later, I was still unable to connect to the database - it was refusing new connections. Either from my worker role or from the Azure Management Website. The Management Window, upon trying to connect,
failed with exactly the same text as error type 2 below.
Further, sys.resource_stats (from the master db, which is still accessible) is reporting that there were 30 active sessions, 30 active workers (see extract below) for four afters after the test ended. Even though during this time period the Azure Cloud
Service that was generating the SQL requests was stopped too (so the client side of any open requests were long since dead). Also,
the CPU, Log Write and Phys Data Read columns in sys.resource_stats are all showing 0 for the four hours after the test ended. This to me suggests a fault condition that isn't clearing server-side.
Why was the database unavailable for four hours? Why did Azure believe that there were 30 open requests? (each request was an insert of 1000 rows, each of 400 bytes, i.e. pretty small so no way should they take this long to process).
PS. To be clear, none of the above is a complaint. I completely accept that the service in in preview, different SLA, etc. I am writing to a) check that I haven't missed anything and b) if this is a bug, to report it.
Appendix
Error Type 1
System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Error Type 2
SqlException: Resource ID : 1. The request limit for the database is 30 and has been reached. See 'http://go.microsoft.com/fwlink/?LinkId=267637' for assistance.
Metrics
The following is an extract from sys.resource_stats for the affected time period. SQL Server seems to wrongly believe/report that there are 30 pending requests between 6:20 and 10:45. It thus blocks any further requests during this time. There
were NO client connections during this time, either new or previously opened.

87.86Hi Chris,
Thanks for testing the new Basic edition and for reporting this issue. Without some more investigation it is hard to tell what exactly has happened here.
To be able to take a closer look I would need some more information from you. Could you please reach out to me via email (firstname DOT lastname AT microsoft DOT com)? I will then let you know what additional information we and will kick-off
the investigation.
Thanks,

</Statement>Hi abishek,
My scenario is basically JDBC(SQL Server)XIJDBC(ORACLE)(Synchronous)
XI pick the date field from JDBC Sender and goes to ORACLE Database and selects records based upon the condition, and response back and put this data into JDBC(SQL Server),
My process successfully upto receive the response from ORACLE system and after response mapping also successful.after that response message is insert into SQL Server.
In SQL server we have two tables,one DATA table and LOG table, If insert the data into DATA table successfully LOG table updated with DATE and STATUS field not successfully insert LOG table update with DATE and Error status field.
So I impleted "stored procedure" in SQL side.
Any way i solved that error.
I am using below XML structure with out table field,i followed below blog.
http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/9618. [original link is broken] [original link is broken] [original link is broken]
My stored procedure name is: XI_SP_KDATA_KLOGDATA
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:MT_DB_SELECT_REQUEST_response xmlns:ns0="urn:pg-siemens-com:POCA0013:sample1">
- <Statement_response>
- <XI_SP_KDATA_KLOGDATA action="EXECUTE">
<EMPNO type="CHAR">901064</EMPNO>
<EMPNAME type="CHAR">Sateesh</EMPNAME>
<ADDRESS type="CHAR">Hyderabad</ADDRESS>
</XI_SP_KDATA_KLOGDATA>
- <XI_SP_KDATA_KLOGDATA action="EXECUTE">
<EMPNO type="CHAR">901000</EMPNO>
<EMPNAME type="CHAR">Ashish</EMPNAME>
<ADDRESS type="CHAR">Bangalore</ADDRESS>
</XI_SP_KDATA_KLOGDATA>
</Statement_response>
</ns0:MT_DB_SELECT_REQUEST_response>
But again i faced one error in Communication channel
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error processing request in sax parser: Error when executing statement for table/stored proc. 'XI_SP_KDATA_KLOGDATA' (structure 'Statement_response'): com.microsoft.sqlserver.jdbc.SQLServerException: Procedure or function XI_SP_KANLOGDATA_KLOGDATA has too many arguments specified.
My doubt is above error is Stored procedure error or XML Structure error?
Don't hesitate to clarify me.
Thank you.

Execute a procedure with a list of array in sql server 2008
HI all,
I have a procedure which has a list of values passed as an array . How can i execute my procedure with array list? how to implement this?Please help me.
Thanks in advance
DeepaHi Deepa,
basically Microsoft SQL Server does not support arrays as data types for procedures. What you can do is creating a type which represents a table definition. This type can than be used in a procedure as the following demo will show:
The first script creates the environment which will be used for the execution
-- 1. create the table as a type in the database
CREATE TYPE OrderItems AS TABLE
ItemId int PRIMARY KEY CLUSTERED
GO
-- 2. demo table for demonstration of results
CREATE TABLE dbo.CustomerOrders
Id int NOT NULL IDENTITY (1, 1) PRIMARY KEY CLUSTERED,
CustomerId int NOT NULL,
ItemId int
GO
-- 3. Insert a few records in demo table
INSERT INTO dbo.CustomerOrders
(CustomerId, ItemId)
VALUES
(1, 1),
(2, 1),
(3, 3),
(1, 3);
GO
-- 4. Create the procedure which accepts the table variable
CREATE PROC dbo.OrderedItemsList
@Orders AS OrderItems READONLY
AS
SET NOCOUNT ON;
SELECT o.*
FROM dbo.CustomerOrders AS O INNER JOIN @Orders AS T_O
ON (o.ItemId = T_O.ItemId);
SET NOCOUNT OFF;
GO
The above script creates the table data type and a demo table with a few demo data. The procedure will accept the table data type as parameter. Keep in mind that table variable parameters have to be READONLY as parameter for procedures!
The second script demonstrates the usage of the above scenario
When the environment has been created the usage is a very simple one as you can see from the next script...
-- 1. Fill the variable table with item ids
DECLARE @o AS OrderItems;
INSERT INTO @o (ItemId)
VALUES
(1), (3);
-- 2. Get the list of customers who bought these items
EXEC dbo.OrderedItemsList @Orders = @o;

Hi Have below requirement,
a. Take the first 7 digits of a Number string and multiply the 1st digit by 8, the 2nd digit by 7 .....etc..... the 6th digit by 3 and the 7th digit by 2;
b. Sum up the values of the above seven multiplication;
c. Subtract 97 from the value at b. above until you have a negative number;
d. Digits 8 and 9 of the number, the “check digits”, will correspond with the absolute value of the negative number determined at c. above.
Example:
Passing input as number specific one, 'SK391313073'
now first 7 digits are 3913130 and perform Sum like this (3*8)+(9*7)+(1*6)+(3*5)+(1*4)+(3*3)+(0*2) [Sum wil be 121]
I have achieved till above through sql,
Now the sum I should subtract with 97 till it get equal with 8th and 9th digit (here I should loop)
in this case
121-97=24 so this is not equal to 73 (last two digits of input)
so now I need to again perform 24-97 which is -73 and abs(-73)=73 so I need to stop here,
All your help is appreciated,,Here's a basic example of a FOR loop type structure in SQL - the pseudo column level serves as the loop variable.
You can use the WITH clause as "programming blocks" to calculate something specific and re-use the output of that in another "programming block".
The following example demonstrates the basic approach:
SQL> var n varchar2(20)
SQL> exec :n := 'SK391313073';
PL/SQL procedure successfully completed.
// parse the input string as per requirements
SQL> with number_parse as (
2 select
3 level as i,
4 substr(:n,level,1) as ch
5 from dual
6 connect by level <= length(:n)
7 )
8 select
9 *
10 from number_parse
11 /

4 9
5 1
6 3
7 1
8 3
9 0
10 7

11 rows selected.
// tad more complex: using this parsing output, determine the 1st 7 digits

4 substr(:n,level,1) as ch

SQL: does if/else work as a query or only in a SP?
I'd like to insert a record if it doesn't exist or UPDATE it
if it does. I'm
doing this through a query via my app:
IF EXISTS (SELECT siteID
FROM weSiteMenusXML
WHERE siteID = 1)
INSERT
INTO weSiteMenusXML(siteID)
VALUES (1) ELSE
UPDATE weSiteMenusXML
SET xml = 'boo'
WHERE siteID = 1
Enterprise manager seems to be fine with this syntax, but it
doesn't
actually do anything. Is SQL if/else logic only applicable to
stored
procedures or is there just something goofy with my syntax?
-DarrelHi Darrel,
If your example below is the same as your actual code in your
app then it
won't do anything. You are basically telling SQL to look if a
record exists
with a siteID of 1 and if there is such a record then insert
a record with
the identical value. If that record doesn't exist then you
are instructing
it to do an update on this non-existent row (siteID of 1).
Surely your SQL
should look something like this:
IF EXISTS (SELECT siteID
FROM weSiteMenusXML
WHERE siteID = 1)
UPDATE weSiteMenusXML
SET xml = 'boo'
WHERE siteID = 1
ELSE
INSERT
INTO weSiteMenusXML(siteID)
VALUES (1)

PL/SQL cursors vs. SQL*plus Select statement
Hi folks, hope you're doing well,
Here is a question that kept me wondering:
Why would I use cursors when i can achieve the same thing with a SQL+ Select statement which is much easier to formulate than a cursor (e.g. you need no declaration, loops etc)?.
Thanks so much,
-aThere is no such thing as a SQL*Plus SELECT statement. The SELECT command is part of the SQL Language - not part of the SQL*Plus (very limited small vocabulary) macro language.
All SQL SELECTs (from client languages) winds up in the SQL Engine as SQL cursors. A SQL Cursor is basically the:
- SQL source code
- SQL "compiled" code (instructions on how to fetch the rows)
On the client side, client cursors (not to be confused with SQL cursors) are used. A client cursor is created in the client language when it makes SQL calls via the database client driver (called the OCI/Oracle Call Interface for Oracle clients).
Typically this is what a client does. It makes a connection to the database and gets a database handler in return. The database handler is the "communication channel" from the client to the db. In Oracle, the database handler in the client refers to the Oracle session (for that client) on db server.
A SQL statement (source code) is used by the client. This can be a SELECT statement you type in at the SQL*Plus command line. It can be a SELECT statement for the PL/SQL cursor command in a stored procedure.
The client creates a SQL handle for this SQL statement, by calling the Oracle client driver. Note that this SQL handle is a client handle - a client cursor for that SQL statement.
E.g.
a) sqlHandle = CreateSQL( databaseHandle, 'SELECT ... FROM ...')
b) sqlHandle.Parse
c) sqlHandle.Execute
After the SQL handle (client cursor) has been executed, the client can fetch rows from it.
This is what SQL*Plus does automatically for you, without you having to write the code to do it. SQL*Plus CONNECT command create a database connection handle. You enter a SELECT statement and SQL*Plus creates a SQL handle (client cursor), executes it, fetches from it, displays the rows, and closes the SQL handle when done.
The same applies to PL/SQL. You can use a SELECT statement just like that in PL/SQL. E.g.
declare
i integer;
begin
select count(*) into i from emp where deptid = 123;
end;This is called an implicit cursor. PL/SQL creates (just like SQL*Plus) an implicit client cursor. It creates and disposes of that client SQL handle for you - you do not need to do it.
Or, you can create an explicit cursor. E.g. declare
cursor c is select count(*) from emp where deptid = 123;
i integer;
begin
open c;
fetch c into i;
close c;
end;The question as to when to use implicit (client) cursors versus explicit (client) cursors depends on your requirements. Do you need to cycle through the results of the SQL? Etc.
And keep in mind that in either case, the SQL Engine creates a SQL cursor anyway on its side.
