PL/SQL :: Differences Between Calling SQL Statement / Procedure?
Apr 22, 2013
I am planing to write the web-application which use Oracle DB 11g.I would like to understand what are the differences (specially, performance issues, steps of execution, optimizer possibilities) between calling SQL statements and PL/SQL procedures/functions. Which approach is more appropriate, and why?
Examples:
a) WebApp->Call("select * from employees where department_id = ?", 10) ;
b) WebApp->Call("? := mypackage.get_emp(?)", refCursor, 10);
create package mypackage is
function get_emp(dep_id in number) return sys_refcursor is
begin
open cur for select * from employees where department_id = dep_id;
end;
end;==========================================
Requirements: High-concurrency, 100+ db sessions, DB will not be used for business-logic.
I am getting a (PL/SQL: ORA-00903: invalid table name) compile error in a procedure using a merge statement. I have seen many examples using this technique and am at a loss as to why I can't compile.
the pipelined function is:
FUNCTION f_crcli_pipe(pi_source_data IN sys_refcursor, pi_limit_size IN PLS_INTEGER DEFAULT pkg_crcli_variables.c_cursor_limit_def) RETURN CRCLI_AA PIPELINED PARALLEL_ENABLE(PARTITION pi_source_data BY ANY) IS
[code].....
the error is pointing to the TABLE function in the USING clause of the merge statement.
I am in the process of creating a trigger for a procedure I created. The procedure is working fine but I keep getting an error on the trigger. I am getting Error(7,5): PL/SQL: Statement ignored AND Error PLS-00306: worng number of types of arguments in call to 'INSERTINTOPHYSLOG'
Here is my procedure:
create or replace PROCEDURE INSERTINTOPHYSLOG AS prec_num long; srec_num long;
The application I am working on uses Oracle HTP procedures to generate HTML pages for our application. I am trying to perform some cleanup when a user closes a web application by clicking the 'X' button in there browser. I am thinking of using the onUnload trigger to call a javascript function, which in turn would call a procedure in my PL/SQL pacakge for cleaning up logical locks on records.
The body tag delaration looks like this code fragment:
Note that clear_locks is a pl/sql stored procedure.So far I have gotten it to pass in the user ID correctly.Is there a way I can call my clear_locks procedure?
I have created this procedure for printing ename,sal,job as output using empno as input:-
CREATE OR REPLACE PROCEDURE p_get ( p_empno NUMBER, p_name OUT VARCHAR2, p_sal OUT NUMBER, p_job OUT VARCHAR2 ) IS BEGIN SELECT ename, sal, job INTO p_name, p_sal, p_job FROM emp WHERE empno = p_empno; END;
Now My Requirement I want to call this procedure using Positional,Named and Mix Methods...I am calling this procedure using Positional Method:-
I am calling a procedure with the following parameters
DECLARE PROFIT_CENTER NUMBER; BEGIN PROFIT_CENTER:= 1109 --( Similarly I am running the proc for 5 more profit_centers 1123,1132, 1122,3211, 1111
one by one by passing values manually, it is taking almost a minute for each profit center
)Prc_test_calc ( PROFIT_CENTER); COMMIT; END; For each profit_center proc is taking 1 mins (Approx) time.
But when I am trying to loop it to call the procedure for each profit_center , I don’t know for what reason it is taking too much time for each profit_center. Anything wrong with the below loop
DECLARE PROFIT_CENTER NUMBER; cursor c_profit is select distinct PROFIT_CENTER from plng_pc where profit_center in (1109, 1123,1132,1122,3211,1111); --
Plng_pc is a table from where profit_center information is getting fetched
BEGIN For pc_rec in c_profit loop Prc_test_calc ( pc_rec .PROFIT_CENTER ); COMMIT; End loop; END;
I searched, found this one hit and according to mateoc15, you cannot commit within a procedure that is called from a trigger. He must be right, because mine is not committing either, nor are any errors given.
Trigger
Create or replace trigger owner_name.table1_trg2 after update on table1 for each row call owner_name.procedure1;
procedure Code (psuedo):
Create or replace procedure1 as begin update table1 set col1 = 'whatever'; commit; exception when others then rollback;
Executing the procedure as owner_name on SQLPlus works fine, but when I update a column of the table via the PL/SQL package (on the web form), the column does not update, telling me that the procedure never fired from the trigger.
I am trying to call a Web service using the SOAP API and I get the following error.
ORA-31020: The operation is not allowed, Reason: For security reasons, ftp and http access over XDB repository is not allowed on server side ORA-06512: at "SYS.XMLTYPE", line 48 ORA-06512: at "MyConnection.SOAP_API", line 121 ORA-06512: at "MyConnection.MyFunction", line 28 31020. 00000 - "The operation is not allowed, Reason: %s" *Cause: The operation attempted is not allowed *Action: See reason and change to a valid operation.
However we do have another procedure that is able to make an HTTP call successfully within the same domain. Hence the ACLs that are required are for making an HTTP call are in place. Is there any other security setting to be tweaked to make the to enable me to make a Webservice call using the SOAP package?
I have a procedure that checks in the table if the daily refresh was successful or not for the previous day. If it failed I would like to receive an email, which I accomplish with calling my EMAIL() procedure. Otherwise call my program_scheduler that will run a shell script.
Below is my procedure:
create or replace PROCEDURE RD_ODS_REFRESH_LOG IS BEGIN FOR i IN ( SELECT RESULT FROM RD_REFRESH_LOG
[code].....
And here is CALL_SHELL job that my procedure calls:
I am trying to call procedure from PRO C Procedure has many parameters and I do not need to put all of them when I call procedure. Is there way to make the same way as in PL/SQL
It's somewhat related to my previous post DBMS_SQL Usage But here I tried to capture whole scenario.
Scenario is like below:
create user a identified by a; grant connect,resource to a; create user b identified by b; grant connect,resource to b; create user c identified by c; grant connect,resource to c;
[code]....
Not getting why the schema is not changing... and how to resolve the error.
I am having an Oracle procedure which return ref cursor. I also want to result one more out parameter result. How Can I call the procedure in SQL. Below is the way I am calling my stored procedure with one parameter.
proc_Test (p_resultset=> My_cursor)
How can I call the procedure when I have one more OUT parameter. Second parameter returns 0 or 1.
I have created two Stord procedures, which does have same input type of input parameter but different output parameters. I want to call these two procedures from a single call and get the combined output. Below is the code I have tried:
CREATE OR REPLACE PROCEDURE sp_all_attribute_difference ( i_product_id_new IN NUMBER, o_product_attr_diff_list OUT product_attr_diff_list, o_usage_attr_list OUT usage_attr_diff_list ) IS [code]....
In a package I have one procedure "setscores_ram_bulk" with collection varaiavles.And other two procedures are
"UpdateRelatedOrders" and "SetGeoFraudScore"
with out collections.I am calling collection procedure "setscores_ram_bulk" in non collection procedures
"UpdateRelatedOrders" and "SetGeoFraudScore".
I am getting the below error.PLS-00306:wrong number or types of arguments in call to 'SETSCORES_RAM_BULK' .I am sending my code.
CREATE OR REPLACE PACKAGE GAFT_PROG_DIT.INTERNAL_SCORING_setscore_Bulk IS TYPE rec_setscores IS RECORD ( pBUID score.buid%TYPE, OrderNum score.order_num%TYPE, ScoreType VARCHAR2(100), p_Score score.velocity_score%TYPE ); [code]....
In my application, we are getting the following exception on calling the Java procedure.
java.sql.SQLException: ORA-29532: Java call terminated by uncaught Java exception: java.lang.OutOfMemoryError ORA-04030: out of process memory when trying to allocate 10804020 bytes (joxp heap,f:OldSpace)
I have a trigger which is calling a stored procedure that has PRAGMA AUTONOMOUS_TRANSACTION defined. The values that are passed from the trigger have been committed already but it appears that the values are not available in the stored procedure. I'm not positive of this since the ability to log/commit is difficult and the timing of the output is confusing me a bit. I'd like to know if it's expected that any passed values are simply available in the stored procedure regardless of the AUTONOMOUS_TRANSACTION?
I am trying to call a shell script through external procedure. To summarize the steps that I followed:
Placed the library file,i.e., the .so file in bin folder of the database server. I have not compiled the .c file and created this. I have taken this from another application.
Then I logged into the sqlplus. Created one library pointing this .so file.
create or replace library ext_proc as '/ngs/app/ivndrptd/bin/execute_cmdlib.so';
After this created the external procedure. This got compiled without any errors.
SQL> create or replace procedure ext_proc_wrapper(in_script IN varchar2) as external library ext_proc NAME "execute_cmd" parameters (in_script string); / Procedure created.
I am trying to execute a script test.ksh which contains a touch command to create a test.txt file.
However irrespective of the procedure running successfully the script is not getting called. I tried several ways of calling the script which are as follows
I have a table that has 10 columns which is used to store the customer information (e.g Gender, Age, Name). And i have wrote a store procedure to compare the before and after value of column since there has a parameter to control which column need/no need to be updated while the value being changed.
For example, master table "CUST" has column (NAME, GENDER, AGE). "CUST_TEMP" is a temporary table to store the input image which has the same table structure as "CUST".
DECLARE bef_val CUST%ROWTYPE; aft_val CUST_TEMP%ROWTYPE; BEGIN SELECT * INTO bef_val FROM CUST WHERE name = 'ABC'; SELECT * INTO aft_val FROM CUST_TEMP WHERE name = 'ABC'; [code]....
For the above case, i need to type 3 times of "sp_compare_val ( bef_val.xxx, aft_val.xxx )" on the program. And if the table has more than 10 columns, i need to type more than 10 times.Thus, is it possible to pass in a dynamic variable while calling the store procedure. let say, where the 'xxx' can be definable?
I have a requirement in which I have to call a packaged procedure created in one database DB1 to other database DB2 through a DBLink. The packaged procedure to be called has refcursor as OUT parameter.
When I run the procedure in DB1 , it works fine: Declare v_ref_data SYS_REFCURSOR; a1 Number; b1 varchar2(100); c1 varchar2(100);
Begin apps.XXCU_DB1_PKG.get_DB1('101062','9138', v_ref_data);
I need to call a PL/SQL stored procedure from a C program. Something like this sample program provided by Oracle -
main() { int i; EXEC SQL BEGIN DECLARE SECTION; /* Define type for null-terminated strings. */ EXEC SQL TYPE asciz IS STRING(20); asciz username[20]; asciz password[20]; [code].......
The question is - how is the Stored procedure get_employees declared ? Or more specifically, how is the salary parameter declared in get_employees ?
We are calling a stored procedure in jsp page. The sql where bottleneck was assumed is giving better performance in sql plus (0.093 seconds) but when called from jsp its taking too much time.
Here is the plan for the sql

I am new to APEX (well all of Oracle really so only have limited knowledge of PL/SQL etc too) but have created a couple of simple applications via wizards. One of these has a tabular form which works fine for updating records for the table that the form was built over but I need a way to write a record to a second (audit) table as well.
My form is used for cycle counting of items in a location. It originally shows the quantities of all the items in a location and allows the user to make corrections by updating any incorrect quantities to the correct value (this would then update the quantity column in the main table). It then needs to calculate the difference between the old and new value and write this as a record to an audit file (might be a positive or negative number).
do I call a procedure once (on submitting the page) and get the procedure to loop through the changed records writing to my audit file OR do I call my procedure once per changed record on the tabular form, if so how do I know what parameters to pass to the procedure?
I have tried researching this online but can find no easy to follow examples. All examples of code I have seen for tabular forms refer to fields referenced by apex_application.g_f01 or f02 etc - how do you know what items on the page these relate to?
