I would like to create record from refcursor. My code:
set serveroutput on
DECLARE
c_curs SYS_REFCURSOR;
v_id NUMBER;
BEGIN
pck_prov.get_value_type_list (1, c_curs); --> procedure called here
-- I guess this is the place where record can be created from cursor.
LOOP
FETCH c_curs
INTO v_id;--instead of fetching into variable I would like to fetch into row
EXIT WHEN c_curs%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(v_id);--if fetching is done into row, only selected columns can be printed, like myrow.id
END LOOP;
CLOSE c_curs;
END;
Please note: I know how to create record from cursor which is defined with select statement as it is described here. What I don't know is how to use same technique for refcursors.
EDIT:
Code from here is just what I need, but it throws error:
set serveroutput on
VAR c_curs refcursor;
EXECUTE pck_prov.get_value_type_list(1, :c_curs);
BEGIN
FOR record_test IN :c_curs LOOP
dbms_output.put_line(record_test.id);
END LOOP;
END;
Error: error PLS-00456: item 'SQLDEVBIND1Z_1' is not a cursor.
Just to clarify question:
In my database there is around 200 packages.
Every package has several stored procedures inside - and usually each procedure is combined with columns from different tables. That is why it would be the best to have some dynamically created cursor, so I can make simple select just like in the example I've posted.
From Oracle 12.1 onward, you could use the DBMS_SQL.return_result procedure. SQL Plus displays the contents of implicit statement results automatically. So, rather than defining explicit ref cursor out parameters, the RETURN_RESULT procedure in the DBMS_SQL package allows you to pass them out implicitly.
DECLARE
c_curs SYS_REFCURSOR;
v_id NUMBER;
BEGIN
pck_prov.get_value_type_list (1, c_curs);
DBMS_SQL.return_result(c_curs); --> Passes ref cursor output implicitly
END;
/
In fact, no need of this separate PL/SQL block, you could add the DBMS_SQL.return_result(c_curs) statement in your original pck_prov.get_value_type_list procedure itself.
Just define a PL/SQL RECORD type that matches the cursor and FETCH into it.
DECLARE
c_curs SYS_REFCURSOR;
TYPE rec_t IS RECORD ( object_name VARCHAR2(30), object_type VARCHAR2(30) );
v_rec rec_t;
BEGIN
OPEN c_curs FOR
SELECT object_name,
object_type
FROM dba_objects
WHERE object_name like 'DBA%TAB%';
LOOP
FETCH c_curs
INTO v_rec;
EXIT WHEN c_curs%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(v_rec.object_name || ' - ' || v_rec.object_type);
END LOOP;
CLOSE c_curs;
END;
DBA_ADVISOR_SQLA_TABLES - VIEW
DBA_ADVISOR_SQLA_TABVOL - VIEW
DBA_ADVISOR_SQLW_TABLES - VIEW
DBA_ADVISOR_SQLW_TABVOL - VIEW
DBA_ALL_TABLES - VIEW
etc...
This is my first (edited) stackoverflow question, so please bear with me.
In Oracle 11g, I have a need to describe/interrogate the underlying columns of a reference cursor returned from a procedure call on another database over a dblink, in which the actual SQL is not always "explicit", but sometimes dynamically generated.
For example:
declare
v_ref_cur sys_refcursor;
v_cur_num number;
v_col_count number;
v_col_table dbms_sql.desc_tab3;
begin
myProc#myDblink(v_ref_cur, 'myvalue');
v_cur_num := dbms_sql.to_cursor_number(v_ref_cur);
dbms_sql.describe_columns3(v_cur_num, v_col_count, v_col_table);
...
end
If myProc() on the other database has an "explicit" SQL statement like:
open cursor for select * from foo where bar = myParam;
The cursor conversion and description (still) work just fine - I can determine the column names, types, lengths, etc returned by the procedure.
BUT, if myProc() on the other database involves dynamic SQL, like:
v_sql := 'select * from foo where bar = ''' || myParam || '''';
open cursor for v_sql;
I get an ORA-01001 invalid cursor error when attempting to call dbms_sql.to_cursor_number().
Is there a way to convert/describe a reference cursor derived from dynamic SQL as called from a remote procedure? If so, how? If not, why not?
Thanks for any/all assistance!
Using DBMS_SQL across a database link raises many different errors, at least some of which are Oracle bugs. Those problems can be avoided by putting all of the logic in a function compiled on the remote server. Then call that function remotely.
--Create and test a database link
create database link myself connect to <schema> identified by "<password>"
using '<connect string or service name>';
select * from dual#myself;
--myProc
create procedure myProc(p_cursor in out sys_refcursor, p_value varchar2) is
begin
--open p_cursor for select * from dual where dummy = p_value;
open p_cursor for 'select * from dual where dummy = '''||p_value||'''';
end;
/
--Simple function that counts and displays the columns. Expected value is 1.
create or replace function count_columns return number is
v_ref_cur sys_refcursor;
v_cur_num number;
v_col_count number;
v_col_table dbms_sql.desc_tab3;
begin
--ORA-01001: invalid cursor
--myProc#myself(v_ref_cur, 'myvalue');
myProc(v_ref_cur, 'myvalue');
--ORA-03113: end-of-file on communication channel
--v_cur_num := dbms_sql.to_cursor_number#myself(v_ref_cur);
v_cur_num := dbms_sql.to_cursor_number(v_ref_cur);
--Compilation error: PLS-00306:
-- wrong number or types of arguments in call to 'DESCRIBE_COLUMNS3'
--dbms_sql.describe_columns3#myself(v_cur_num, v_col_count, v_col_table);
dbms_sql.describe_columns3(v_cur_num, v_col_count, v_col_table);
return v_col_count;
end;
/
begin
dbms_output.put_line('Number of columns: '||count_columns#myself());
end;
/
Number of columns: 1

Best way/tool to get the results from an oracle package procedure
Oracle SQL Developer: Show REFCURSOR Results in Grid?
I am new to Oracle SQL Developer. I am using Oracle SQL Developer Version 3.0.
I was trying to test my SP using the following query.
DECLARE
type output_cursor is ref cursor;
P_CURSOR output_cursor;
BEGIN
P_CURSOR := NULL;
myPackage.mySPTest ( P_NOTIFICATION_ID => 1975357,P_CURSOR => P_CURSOR) ;
END;
When I ran the above query in my Oracle SQL Developer, I am getting a message 'anonymus block completed' and its not showing any result.
Can anyone help me, how to see the result.
.
You can use a bind variable declared in SQL Developer to hold and show the results:
var r refcursor;
exec myPackage.mySPTest(P_NOTIFICATION_ID => 1975357, P_CURSOR => :r);
print r;
exec is shorthand for an anonymous block so this is equivalent to:
var r refcursor;
begin
myPackage.mySPTest(P_NOTIFICATION_ID => 1975357, P_CURSOR => :r);
end;
/
print r;
Unless P_CURSOR is declared as something unhelpful, maybe...
To view your cursor results you need to loop through your cursor and print values. You need to know column names for what your cursor is returning. You can do something like:
DECLARE
type output_cursor is ref cursor;
P_CURSOR output_cursor;
BEGIN
P_CURSOR := NULL;
DOCTORS_APP.get_reminders ( P_NOTIFICATION_ID => 1975357,P_CURSOR => P_CURSOR) ;
//replace Column1 and Column2 with actual column names
FOR CUR_VAL in P_CURSOR LOOP
DBMS_OUTPUT.PUT_LINE(CUR_VAL.Column1||' '||CUR_VAL.Column2);
END LOOP;
END;
I'm trying to call an Oracle stored proc using SQL Developer. The proc outputs results using a sys_refcursor. I right click in the proc window which brings up the Run PL/SQL window. When I choose the proc I want it creates all the input params etc for me. Below is the code I'm using to try and loop through the sys_refcursor and output the results, but I'm getting an error on the 'v_rec v_Return%rowtype;' line :
ORA-06550: line 6 column 9:
PLS-00320: the declaration of the type of this expression is incomplete or malformed.
ORA-06550: line 6 column 9:
PL/SQL: Item ignored
vendor code 6550
I found the looping code on a couple of other websites and it seems to be the way to do it but it's not working for me no matter what I try. Another question - on the DBMS_OUTPUT.PUT_LINE('name = ' || v_rec.ADM) am I referencing the v_rec correctly i.e. is v_rec."column_name" the correct way??
I'm not that used to Oracle and have never used SQL plus. Any suggestions appreciated.
DECLARE
P_CAE_SEC_ID_N NUMBER;
P_PAGE_INDEX NUMBER;
P_PAGE_SIZE NUMBER;
v_Return sys_refcursor;
v_rec v_Return%rowtype;
BEGIN
P_CAE_SEC_ID_N := NULL;
P_PAGE_INDEX := 0;
P_PAGE_SIZE := 25;
CAE_FOF_SECURITY_PKG.GET_LIST_FOF_SECURITY(
P_CAE_SEC_ID_N => P_CAE_SEC_ID_N,
P_PAGE_INDEX => P_PAGE_INDEX,
P_PAGE_SIZE => P_PAGE_SIZE,
P_FOF_SEC_REFCUR => v_Return
);
-- Modify the code to output the variable
-- DBMS_OUTPUT.PUT_LINE('P_FOF_SEC_REFCUR = ');
loop
fetch v_Return into v_rec;
exit when v_Return%notfound;
DBMS_OUTPUT.PUT_LINE('name = ' || v_rec.ADM);
end loop;
END;
Your problem is here:
v_Return sys_refcursor;
v_rec v_Return%rowtype;
v_Return is a cursor variable and has no specific structure (list of columns), so v_Return%rowtype is not a valid record structure to declare v_rec. It is even possible for different calls to the procedure to return cursors with different structures.
You know what you are expecting the structure of the returned cursor to be (but Oracle doesn't) so you need to explicitly define the appropriate record structure e.g.
type t_row is record (empno number, ename varchar2(30));
v_rec t_row;
You need a strongly typed ref cursor to be able to define it as a %ROWTYPE.
Example here
#Tony Andrews thanks for this it gave me a better idea where I was going wrong. Still having problems though - here's a shortened version of my proc. It's a bit complex in that it's selecting all fields from a subquery and 2 other values:
open p_fof_sec_refcur for
SELECT *
FROM(
SELECT securities.*, rownum rnum, v_total_count
FROM
(
SELECT
CFS.CAE_SEC_ID,
CFS.FM_SEC_CODE,
...
FROM
CAEDBO.CAE_FOF_SECURITY CFS
INNER JOIN caedbo.CAE_DATA_SET_ELEMENT CDSE_STAT
ON (CDSE_STAT.DATA_SET_ELEMENT_ID = CFS.APPR_STATUS)
...
WHERE APPR_STATUS = NVL(p_appr_status, APPR_STATUS)
...
)securities
)
WHERE rnum between v_pgStart and v_pgEnd;
I explicitly defined the output structure as below to match the return fields from the proc but I'm still getting an error:
v_Return sys_refcursor;
type t_row is record (CAE_SEC_ID NUMBER,FM_SEC_CODE VARCHAR2(7),...rnum number, v_total_count number);
v_rec t_row;
The error I get is
ORA-06504: PL/SQL: Return types of Result Set variables or query do not match
ORA-06512: at line 45
I'm just wondering is the "rownum rnum, v_total_count" part tripping me up. I'm pretty sure I have all the other fields in the output structure correct as I copied them directly from the proc.
I am trying to run a stored procedure that has multiple in and out parameters. The procedure can only be viewed in my Connections panel by navigating
Other Users | <user> | Packages | <package> | <procedure>
If I right click , the menu items are "Order Members By..." and "Create Unit Test" (greyed out). The ability to "Run" the procedure does not seem possible when it's accessed by user.
I have been trying to find an example of how to create an anonymous block so that I can run the procedure as a SQL file, but haven't found anything that works.
Does anyone know how I can execute this procedure from SQL Developer? I am using Version 2.1.1.64.
EDIT 1:
The procedure I want to call has this signature:
user.package.procedure(
p_1 IN NUMBER,
p_2 IN NUMBER,
p_3 OUT VARCHAR2,
p_4 OUT VARCHAR2,
p_5 OUT VARCHAR2,
p_6 OUT NUMBER)
If I write my anonymous block like this:
DECLARE
out1 VARCHAR2(100);
out2 VARCHAR2(100);
out3 VARCHAR2(100);
out4 NUMBER(100);
BEGIN
EXECUTE user.package.procedure (33,89, :out1, :out2, :out3, :out4);
END;
I get the error:
Bind Varialbe "out1" is NOT DECLCARED
anonymous block completed
I've tried initializing the out* variables:
out1 VARCHAR2(100) := '';
but get the same error:
EDIT 2:
Based on Alex's answer, I tried removing the colons from in front of the params and get this:
Error starting at line 1 in command:
DECLARE
out1 VARCHAR2(100);
out2 VARCHAR2(100);
out3 VARCHAR2(100);
out4 NUMBER(100);
BEGIN
EXECUTE user.package.procedure (33,89, out1, out2, out3, out4);
END;
Error report:
ORA-06550: line 13, column 17:
PLS-00103: Encountered the symbol "USER" when expecting one of the following:

The symbol ":=" was substituted for "USER" to continue.
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
With simple parameter types (i.e. not refcursors etc.) you can do something like this:
SET serveroutput on;
DECLARE
InParam1 number;
InParam2 number;
OutParam1 varchar2(100);
OutParam2 varchar2(100);
OutParam3 varchar2(100);
OutParam4 number;
BEGIN
/* Assign values to IN parameters */
InParam1 := 33;
InParam2 := 89;
/* Call procedure within package, identifying schema if necessary */
schema.package.procedure(InParam1, InParam2,
OutParam1, OutParam2, OutParam3, OutParam4);
/* Display OUT parameters */
dbms_output.put_line('OutParam1: ' || OutParam1);
dbms_output.put_line('OutParam2: ' || OutParam2);
dbms_output.put_line('OutParam3: ' || OutParam3);
dbms_output.put_line('OutParam4: ' || OutParam4);
END;
/
Edited to use the OP's spec, and with an alternative approach to utilise :var bind variables:
var InParam1 number;
var InParam2 number;
var OutParam1 varchar2(100);
var OutParam2 varchar2(100);
var OutParam3 varchar2(100);
var OutParam4 number;
BEGIN
/* Assign values to IN parameters */
:InParam1 := 33;
:InParam2 := 89;
/* Call procedure within package, identifying schema if necessary */
schema.package.procedure(:InParam1, :InParam2,
:OutParam1, :OutParam2, :OutParam3, :OutParam4);
END;
/
-- Display OUT parameters
print :OutParam1;
print :OutParam2;
print :OutParam3;
print :OutParam4;
Executing easy. Getting the results can be hard.
Take a look at this question I asked Best way/tool to get the results from an oracle package procedure
The summary of it goes like this.
Assuming you had a Package named mypackage and procedure called getQuestions. It returns a refcursor and takes in string user name.
All you have to do is create new SQL File (file new). Set the connection and paste in the following and execute.
var r refcursor;
exec mypackage.getquestions(:r, 'OMG Ponies');
print r;
For those using SqlDeveloper 3+, in case you missed that:
SqlDeveloper has feature to execute stored proc/function directly, and output are displayed in a easy-to-read manner.
Just right click on the package/stored proc/ stored function, Click on Run and choose target to be the proc/func you want to execute, SqlDeveloper will generate the code snippet to execute (so that you can put your input parameters). Once executed, output parameters are displayed in lower half of the dialog box, and it even have built-in support for ref cursor: result of cursor will be displayed as a separate output tab.
Open the procedure in SQL Developer and run it from there. SQL Developer displays the SQL that it runs.
BEGIN
PROCEEDURE_NAME_HERE();
END;
Use:
BEGIN
PACKAGE_NAME.PROCEDURE_NAME(parameter_value, ...);
END;
Replace "PACKAGE_NAME", "PROCEDURE_NAME", and "parameter_value" with what you need. OUT parameters will need to be declared prior to.
Though this question is quite old, I keep stumbling into same result without finding an easy way to run from sql developer.
After couple of tries, I found an easy way to execute the stored procedure from sql developer itself.
Under packages, select your desired package and right click on the package name (not on the stored procedure name).
You will find option to run. Select that and supply the required arguments. Click OK and you can see the output in output variables section below
I'm using SQL developer version 4.1.3.20
None of these other answers worked for me. Here's what I had to do to run a procedure in SQL Developer 3.2.20.10:
SET serveroutput on;
DECLARE
testvar varchar(100);
BEGIN
testvar := 'dude';
schema.MY_PROC(testvar);
dbms_output.enable;
dbms_output.put_line(testvar);
END;
And then you'd have to go check the table for whatever your proc was supposed to do with that passed-in variable -- the output will just confirm that the variable received the value (and theoretically, passed it to the proc).
NOTE (differences with mine vs. others):
No : prior to the variable name
No putting .package. or .packages. between the schema name and the procedure name
No having to put an & in the variable's value.
No using print anywhere
No using var to declare the variable
All of these problems left me scratching my head for the longest and these answers that have these egregious errors out to be taken out and tarred and feathered.
Can't believe, this won't execute in SQL Developer:
var r refcursor;
exec PCK.SOME_SP(:r,
'02619857');
print r;
BUT this will:
var r refcursor;
exec TAPI_OVLASCENJA.ARH_SELECT_NAKON_PRESTANKA_REG(:r, '02619857');
print r;
Obviously everything has to be in one line..
Using SQL Developer Version 4.0.2.15 Build 15.21 the following works:
SET SERVEROUTPUT ON
var InParam1 varchar2(100)
var InParam2 varchar2(100)
var InParam3 varchar2(100)
var OutParam1 varchar2(100)
BEGIN
/* Assign values to IN parameters */
:InParam1 := 'one';
:InParam2 := 'two';
:InParam3 := 'three';
/* Call procedure within package, identifying schema if necessary */
schema.package.procedure(:InParam1, :InParam2, :InParam3, :OutParam1);
dbms_output.enable;
dbms_output.put_line('OutParam1: ' || :OutParam1);
END;
/
To run procedure from SQL developer-only execute following command
EXECUTE PROCEDURE_NAME;
I had a stored procedure that returned a cursor, in my case it was actually of a custom package type (T_CURSOR, looks like a convention to me) that is defined as REF CURSOR.
There may be a better way to do this, but I defined variables for all the columns of the table that the cursor was iterating, looped the cursor fetching each row into those variables, then printed them out.
SET serveroutput on;
DECLARE
testvar number;
v_cur SYS_REFCURSOR;
ORIGINAL_EMP_NUM NUMBER;
TEMPORARY_EMP_NUM NUMBER;
ORG_UNIT_CODE VARCHAR2(2 BYTE);
MRU_CODE VARCHAR2(10 BYTE);
CTRL_COMPANY_CODE VARCHAR2(10 BYTE);
IS_TEMP_FLAG VARCHAR2(1 BYTE);
BEGIN
testvar := 420;
foo.updates.get_temporary_authorisations(testvar, v_cur);
dbms_output.enable;
dbms_output.put_line(testvar);
LOOP
FETCH v_cur INTO ORIGINAL_EMP_NUM, TEMPORARY_EMP_NUM, ORG_UNIT_CODE, MRU_CODE, CTRL_COMPANY_CODE, IS_TEMP_FLAG;
EXIT WHEN v_cur%NOTFOUND;
dbms_output.put_line(ORIGINAL_EMP_NUM || ',' || TEMPORARY_EMP_NUM || ',' || ORG_UNIT_CODE || ',' || MRU_CODE|| ',' || CTRL_COMPANY_CODE|| ',' || IS_TEMP_FLAG);
END LOOP;
CLOSE v_cur;
END;
I wasn't able to get #Alex Poole answers working. However, by trial and error, I found the following works (using SQL Developer version 3.0.04). Posting it here in case it helps others:
SET serveroutput on;
DECLARE
var InParam1 number;
var InParam2 number;
var OutParam1 varchar2(100);
var OutParam2 varchar2(100);

var OutParam4 number;

InParam1 := 33;
InParam2 := 89;
/* Call procedure within package, identifying schema if necessary */
schema.package.procedure(InParam1, InParam2,
OutParam1, OutParam2, OutParam3, OutParam4);
/* Display OUT parameters */
dbms_output.put_line('OutParam1: ' || OutParam1);
dbms_output.put_line('OutParam2: ' || OutParam2);
dbms_output.put_line('OutParam3: ' || OutParam3);
dbms_output.put_line('OutParam4: ' || OutParam4);
END;
--for setting buffer size needed most of time to avoid `anonymous block completed` message

V_OUT_2 => V_OUT_2
);
V_OUT_1 := V_OUT_1;
V_OUT_2 := V_OUT_2;
-- console output, no need to open DBMS OUTPUT seperatly
-- also no need to print each output on seperat line
DBMS_OUTPUT.PUT_LINE('Ouput => ' || V_OUT_1 || ': ' || V_OUT_2);
END;
Creating Pl/SQL block can be painful if you have a lot of procedures which have a lot of parameters. There is an application written on python that do it for you.
It parses the file with procedure declarations and creates the web app for convenient procedure invocations.
var out_para_name refcursor;
execute package_name.procedure_name(inpu_para_val1,input_para_val2,... ,:out_para_name);
print :out_para_name;
