Execute immediate return
Hi,
I want to know if it's possible to use the return clause with the insert statement with EXECUTE IMMEDIATE.
My code looks like:
execute immediate('INSERT INTO '||p_nameDB||'.TableName (col1) VALUES (:1)
') using p_col1;
The id is generated automatically with a trigger (and a sequence). And I want to recuperate it in a variable after the insert statement. I don't want to do a seq.currval after because i'm afraid that there will be a mix match with the sequence and the id if 2 persons accede at the same time.
thanks
execute immediate 'insert into trial (a) values (:1) returning a into :2' using a1 returning into x ;

EXECUTE IMMEDIATE dynamic statement and return procedure value
Hello guys,
How can i return values from procedure using EXECUTE IMMEDIATE statment?
I made easy example:
CREATE OR REPLACE PACKAGE pac_test
IS
PROCEDURE pro_calc_average( p_age_1 IN NUMBER,
p_age_2 IN NUMBER,
p_age_3 IN NUMBER,
v_out OUT NUMBER);
PROCEDURE pro_calc(p_age_1 IN NUMBER,
p_age_2 IN NUMBER,
p_age_3 IN NUMBER);
END;
CREATE OR REPLACE PACKAGE BODY pac_test
IS
PROCEDURE pro_calc_average( p_age_1 IN NUMBER,
p_age_2 IN NUMBER,
p_age_3 IN NUMBER,
v_out OUT NUMBER)
IS
BEGIN
v_out:=(p_age_1+p_age_2+p_age_3)/3;
END pro_calc_average;
PROCEDURE pro_calc(p_age_1 IN NUMBER,
p_age_2 IN NUMBER,
p_age_3 IN NUMBER)
IS
x number;
v_sql varchar2(4000);
BEGIN
v_sql:='pac_test.pro_calc_average('||p_age_1||','||p_age_2||','||p_age_3||',x)';
dbms_output.put_line(v_sql);
EXECUTE IMMEDIATE v_sql;
dbms_output.put_line(' ====> '||x);
END pro_calc;
END;
-- Run procedures [Faild]
EXEC pac_test.pro_calc(2,9,19);
When i run:
DECLARE
x number;
BEGIN
pac_test.pro_calc_average(2,9,9,x);
dbms_output.put_line(' ====> '||x);
END;
It's works, but this is not what i am looking for.
Thank you guys,

EXECUTE IMMEDIATE v_sql;
pack_local_var:=pac_var; /* added new*/
dbms_output.put_line(pack_local_var); /* added new*/
END pro_calc;
END;Declared a package variable.
But be aware this variable is accessible to everyone and they can read or change its value if they have the right privileges.

Obtaining a collection as a return from an execute immediate pl/sql block
version 10.2
I need to obtain the collection back from the execute immediate of a pl/sql block:
procedure block(owner varchar2) is
stmt long;

begin
stmt := '
begin
dbms_stats.gather_schema_stats(''' || owner || '''

execute immediate stmt returning into objecttab_coll;
-- do more stuff here
end block;I have tried this + a few variations but with no luck. In looking through the docs I do not see an example. can this be done?
Thanks
OxI dont find any need for an execute immediate here. This must be just enough.
procedure block(owner varchar2)
is

Dyn sql execute immediate A plsql block returning sql%rowcount of rows inserted
I would like to get the number of rows inserted in a dynamic sql statement like following.
execute immediate
'begin insert into a(c1,c2,c3)
(select ac1,ac2,ac3 from ac where ac1=:thekey
UNION select tc1,tc2,tc3 from tc where tc1=:otherkey); end;' using in key1,in key2;
I have tried per the oracle8i dyn sql chapter in doc RETURN sql%rowcount won't compile.
also add this to statement 'returning sql%rowcount into :rowcount'
no luck.
any ideas.?
thanks.Quick comment first - I'm not sure why you are even using dynamic SQL here. There is nothing dynamic about your statement. It is equivalent to just:
insert into a (c1, c2, c3)
select ac1, ac2, ac3
from ac
where ac1 = key1
UNION
select tc1, tc2, tc3
from tc
where tc1 = key2;Unless you are really dynamically changing a table or column name here and just didn't show it in your example, you certainly don't want the overhead of NDS for this insert in this situation.
In any case, you just need to evaluate SQL%ROWCOUNT in the next statement.
insert ...;
if sql%rowcount = 0 then
-- nothing was inserted
end if; -
How to use Execute Immediate to execute a procedure and return a cursor?
The procedure name is unknown until run time so I have to use Execute immediate to execute the procedure, the procedure return a cursor, but I can't figure out the right syntax to pass the cursor out.
To simplify the issue here, I create two procedures as examples.Assume I have a procedure called XDTest:
p_cur OUT SYS_REFCURSOR
IS
BEGIN
OPEN p_cur FOR
Select * from dummy_table;
END XDTest;
In another procedure, I want to use Execute Immediate to execute XDTest and obtain the result that return from the cursor into a local cursor so I can process the records:
p_cur OUT SYS_REFCURSOR
IS
l_cur SYS_REFCURSOR;
BEGIN
execute immediate 'BEGIN XDTest (:1); END;' using OUT l_cur;
END XDTest2;
However, this is not working, I get ORA-03113: end-of-file on communication channel error.
What syntax should I use here?
Cheerswell...
I update the XDTest2 procedure as below but when execute it get exceptions.I think the v_sqlstmt syntax is wrong, but I don't know what meant to be correct, please give some suggestions .
Cheers

EXECUTE IMMEDIATE with an update FUNCTION returning VARCHAR2
I need to execute immediate a stored Function (that updates the database) and returns a VARCHAR2 value.
What does my execute immediate statement look like:
EXECUTE IMMEDIATE 'BEGIN my_function_call; END;' RETURNING INTO return_variable;A set of procedures would be far preferable to a set of functions if you're doing DML.
Additionally, I'd get rid of the status value entirely and just raise an exception if there is an error. It's a heck of a lot easier to catch (or propagate) exceptions correctly than to ensure that each and every piece of code that calls these procedures checks the return code and acts appropriately. It's way too easy to miss/ hide an error in a missed return code.

Error while insert data using execute immediate in dynamic table in oracle
Error while insert data using execute immediate in dynamic table created in oracle 11g .
first the dynamic nested table (op_sample) was created using the executed immediate...
object is
CREATE OR REPLACE TYPE ASI.sub_mark AS OBJECT (
mark1 number,
mark2 number
t_sub_mark is a class of type sub_mark
CREATE OR REPLACE TYPE ASI.t_sub_mark is table of sub_mark;
create table sam1(id number,name varchar2(30));
nested table is created below:
begin
EXECUTE IMMEDIATE ' create table '||op_sample||'
(id number,name varchar2(30),subject_obj t_sub_mark) nested table subject_obj store as nest_tab return as value';
end;
now data from sam1 table and object (subject_obj) are inserted into the dynamic table
declare
subject_obj t_sub_mark;
begin
subject_obj:= t_sub_mark();
EXECUTE IMMEDIATE 'insert into op_sample (select id,name,subject_obj from sam1) ';
end;
and got the below error:
ORA-00904: "SUBJECT_OBJ": invalid identifier
ORA-06512: at line 7
then when we tried to insert the data into the dynam_table with the subject_marks object as null,we received the following error..
execute immediate 'insert into '||dynam_table ||'
(SELECT887684 wrote:
ORA-00904: "SUBJECT_OBJ": invalid identifier
ORA-06512: at line 7The problem is that your variable subject_obj is not in scope inside the dynamic SQL you are building. The SQL engine does not know your PL/SQL variable, so it tries to find a column named SUBJECT_OBJ in your SAM1 table.
If you need to use dynamic SQL for this, then you must bind the variable. Something like this:
EXECUTE IMMEDIATE 'insert into op_sample (select id,name,:bind_subject_obj from sam1) ' USING subject_obj;Alternatively you might figure out to use static SQL rather than dynamic SQL (if possible for your project.) In static SQL the PL/SQL engine binds the variables for you automatically. -
Java Stored Procedure in EXECUTE IMMEDIATE
Hi,
I need advice for the following.
I'm on Oracle 11g R2. I'm testing application in Oracle 11gR1 and R2 and Oracle Express.
Purpose is to generate XML reports.
I have PLSQL Stored Procedure which does that, but since there is bug in Oracle11gR2 related to XMLTRANSFORM I have and Java Stored Procedure which is workaround. They are both compiled, valid etc.
Java class is :
import java.io.PrintWriter;
import java.io.Writer;
import oracle.xml.parser.v2.DOMParser;
import oracle.xml.parser.v2.XMLDocument;
import oracle.xml.parser.v2.XSLProcessor;
import oracle.xml.parser.v2.XSLStylesheet;
* This class is used as Java stored procedure
* There is a bug on Oracle11gR2, related to the limitation on the number of style sheet instructions
* This stored procedure is workaround when PLSQL code can not be used.
* File must not have package, otherwise is wrongly compiled in DB
public class JavaXslt {
public static void XMLTtransform(oracle.sql.CLOB xmlInput,oracle.sql.CLOB xslInput,oracle.sql.CLOB output) throws Exception{
DOMParser parser;
XMLDocument xml;
XMLDocument xsldoc;
try{
parser = new DOMParser();
parser.parse(xmlInput.getCharacterStream());
xml = parser.getDocument();
parser.parse(xslInput.getCharacterStream());
xsldoc = parser.getDocument();
XSLProcessor processor = new XSLProcessor();
XSLStylesheet xsl = processor.newXSLStylesheet(xsldoc);
Writer w = output.setCharacterStream(1L);
PrintWriter pw = new PrintWriter(w);
processor.processXSL(xsl, xml, pw);
}catch (Exception ex){
throw ex;
PROCEDURE Java_XmlTransform (xml CLOB, xslt CLOB, output CLOB) AS LANGUAGE JAVA
NAME 'JavaXslt.XMLTtransform(oracle.sql.CLOB, oracle.sql.CLOB, oracle.sql.CLOB)';
I'm calling Java stored procedure from PLSQL Stored procedure (if it is Oracle11gR2) like that :
Java_Proc.Java_XmlTransform(inputXML, xslt, res);
So till here everything works ok. XSLT as applied and output XML (res) is OK.
But when Oracle Express is used Java is out of the question, so there is no Java stored procedure. Howewer PLSQL Stored procedure is still needed.
So I had to put call to Java Stored procedure in EXECUTE IMMEDIATE statement in order to compile to PLSQL package.
But when I do that :
EXECUTE IMMEDIATE 'BEGIN Java_Proc.Java_XmlTransform (:1, :2, :3); END;' USING inputXML, xslt, res;
result value CLOB (res) has zero length...
What am I missing? Should i set return value to Java class?
Hope my explanations are clear though.
ThanksHi odie_63,
Thanks for quick response.
I didn't clearly explained.
When using Oracle 11gR1 and Oracle Express I'm using only PLSQL Procedure.
When using Oracle 11gR2 i have to use Java Stored procedure because there is documented bug in R2.
That's why i have to use EXECUTE IMMEDIATE. I don't know which version is the client DB and whether there is or no Java procedures.
I did tried
EXECUTE IMMEDIATE 'BEGIN Java_Proc.Java_XmlTransform (:1, :2, :3); END;' USING IN inputXML, IN xslt, OUT res; and the result was ORA-06537: OUT bind variable bound to an IN position
When using IN OUT for last parameter i.e.
EXECUTE IMMEDIATE 'BEGIN Java_Proc.Java_XmlTransform (:1, :2, :3); END;' USING IN inputXML, IN xslt, IN OUT res;
there is no exception, but still DBMS_LOB.getlength(res) = 0
Thanks -
Execute immediate with using clause to pass column name dynamically
Hai,
Is there any way using execute immeidate to pass the column name dynamically. I used to pass the column value as dynamic with the help of "Using clause" . But if i use to pass column name, it is giving numberic error at run time. Eg,. for testing has been given below.
1. Column value as dynamic, which is working correctly.
create or replace function testexeimm (acctnum char)
return number as
acctbal number;
begin
execute immediate 'select balance from acct_master where acct_no=:a' into acctbal using acctnum;
return acctbal;
end;
2. Column name as dynamic which is not working
create or replace function testexeimm (colnam char)
return char as
acctbal char;
begin
execute immediate 'select :a from ch_acct_mast where rownum=1' into acctbal using colnam;
return acctbal;
end;
Any help in this regard will be highly appericated.
Regards
SridharSo the variable has to be numeric too:
create or replace function testexeimm (colnam char)
return number as
acctbal number;
begin
execute immediate 'select '|||colnam||' from ch_acct_mast where rownum=1' into acctbal;
return acctbal;
end;Max

Using EXECUTE IMMEDIATE with an NVARCHAR2 parameter
Hi everyone,
In the system I'm working on, my stored procedure receives an NVARCHAR2 parameter which contains a complete SQL statement. e.g.
'UPDATE SomeTable SET SomeTable.Value = 0'
I want to be able to execute this dynamically, using EXECUTE IMMEDIATE, but I've encountered a problem where this is apparently not supported (because the string is Unicode).
It is crucial that the string stays as Unicode, because of the data that may possible be baked into the SQL statement, and so casting it off to a VARCHAR2, or changing the parameter type, is not acceptable.
Is there a work-around for this issue? Even if it has a performance hit, it will be better than nothing :)
I've tried something like this;
declare
myVal VARCHAR2(256);
begin
myVal := 'UPDATE SomeTable SET SomeTable.Value = 2';
execute immediate 'BEGIN :x; END;' using myVal;
end;
But I get an error;
"bind variable 'X' not allowed in this context"
Has anyone any ideas?
Thanks for your help,
Chrisuhmm, I'm not sure if this is a valid testcase. the string could still be converted into ascii or we8iso8859p1 or whatever 1byte-character set you want.
What I think you should test is a two-byte character as part of SQL, PL/SQL resp. as in SQL all words are defined you can not enlarge it with a 2byte word. But in PL/SQL you could define your own variable. If this variable name itself contains a 2byte character, I guess it will fail.
(I have used l_vär and l_vér as variable names in my example)
Message was edited by:
Leo Mannhart
According to the PL/SQL Reference Guide PL/SQL consists of:
PL/SQL programs are written as lines of text using a specific set of characters:
Upper- and lower-case letters A .. Z and a .. z
Numerals 0 .. 9
Symbols ( ) + - * / < > = ! ~ ^ ; : . ' @ % , " # $ & _ | { } ? [ ]
Tabs, spaces, and carriage returns
This seems no longer up-to-date as I could define a variable l_vär for instance as long as I use a 1byte char set (like iso8859p1). The same variable name as a n-byte char set like UTF-8 will give an error as my example shows. -
Execute immediate for stored procedure with out parameter
Hi,
I have problem with dynamically executing the statement hope anyone can help me.
I have a table which stores the procedure names. and procedure parameter values are stored on another column with parameter values coming from java side.
I have to create a procedure that dynamically executes the procedure on table1 with the values from table 2.
Now I'm getting real trouble to execute immediate this proc with parameters. I tried the DBMS_SQL package as well.
Problem is you need to mention the OUT mode specifically for the out parameter. Can anybody plz help me with this issue??
TABLE1_
PROCESS_ID PROC_NAME
1 proc1(p1 IN number, p2 IN varchar2, p3 OUT varchar2)
2 proc2(p1 IN number, p2 out varchar2, p3 OUT varchar2)

Thank YouSounds like an appalling design and a nightmare waiting to happen.
Why not have your Java just call the correct procedures directly?
Such design smells badly of an entity attribute value modelling style of coding. Notoriously slow, notoriously buggy, notoriously hard to maintain, notoriously hard to read. It really shouldn't be done like that. -
Need suggestion on PLSQL Create and EXECUTE IMMEDIATE
Most of you already know plsql doesn't like create table, so we have to use EXECUTE IMMEDIATE for creating table. What if I want to see if the table exist, if not then create the table, later I will insert data into that table.
My problem is it returned me the error saying I am try to insert into a non existing table when trying to compile my code. I think plsql doesn't pick up the execute statement.
what I did is, both create and insert are executed by using EXECUTE IMMEDIATE. Anyone have such experience before and willing to share your knowledge?
PS: I am having same problem for creating sequence as well.I think plsql doesn't pick up the execute statement.Since it is a runtime instruction, it will pick it up at runtime. but to be able to run, it needs to compile the code and in order to compile (so it can run) the code it needs that table/sequence you are referencing to exist already. So, you need to run the code to get the table and run needs to compile the code and compile needs the table to compile. can't go from here to there when you try to mix dynamic sql with static sql on the same object within the same program unit (or dependent units).

Execute immediate of Anonymous pl/sql block stored in a VARCHAR2 DB Column
Hi Guys,
I really hope someone can help me with this.
I have the following pl/sql anonymous block stored in a varchar2 database column.
declare
l_my_val varchar2(32767);

WHERE a.JSATFA_ID = 82
AND a.SPECIFIC_ACTIVITY_LOV_ID = l.LOV_ID
AND m.ACTIVITY_ID(+) = a.ACTIVITY_ID
AND m.CLASSIFICATION_LOV_ID = l2.LOV_ID(+);
begin
for each_row in c_activity loop
l_my_val := l_my_val || ', ' || each_row.value1;
end loop;
:l_value := ltrim (l_my_val, ', ');
end; The code is select out of the database and assigned to a local variable within my pl/sql package. The following code should demonstrate what I'm trying to achieve:
declare
l_sql varchar2(32767);
l_value varchar2(32767);
begin
select query_sql into l_sql from lov where lov_id = 100;
execute immediate l_sql using out :l_value;
dbms_output.put_line(l_value);
end;However Oracle (10.2.0.2) seems to be doing something funny with the single quotes. and gives the following error:
ORA-06550: line 1, column 1:

end loop;
:l_value := ltrim (l_my_val, ', ');
end;
~';
execute immediate l_sql using out :l_value;
dbms_output.put_line(l_value);
end;It works perfectly. Notice I have used the q syntax when embedding the sql directly into the package.
I have tried
- appending the q syntax directly to query_sql stored in the database
- escaping the quotes i.e. ' become ''
Neither method seem to work. We are running 10.2.0.2 on Windows Server 2003. If anyone has any suggestions I would love to hear from you as this has me stumped.

l_value varchar2(32767);
begin
select query_sql into l_sql from lov where lov_id = 100;
dbms_output.put_line(l_sql);
end;
You'll see something like that:
SELECT
l.DESCRIPTION || decode(l2.DESCRIPTION,null,'',l2.description, '-' || l2.description) || decode(a.DT,'Y',' - Distributed Training','N',null,null) as value1
FROM ACTIVITY a
,MOUNTAINEERING m
,LOV l
,LOV l2
WHERE a.JSATFA_ID = 82
AND a.SPECIFIC_ACTIVITY_LOV_ID = l.LOV_ID
AND m.ACTIVITY_ID(+) = a.ACTIVITY_ID
AND m.CLASSIFICATION_LOV_ID = l2.LOV_ID(+);
you need to duplicate the '
you can do many things like:
CTH@> select * from sqls;
C
select first_name || ' ' || last_name as value1 from employees where rownum=1
1 fila seleccionada.
CTH@>
CTH@> ;
1 declare
2 l_sql varchar2(32767);
3 l_value varchar2(32767);
4 type generic_cursor is ref cursor;
5
6 c generic_cursor;
7
8 begin
9 select replace(c, ''', ''''') into l_sql from sqls;
10
11 execute immediate l_sql into l_value;
12 dbms_output.put_line(l_value);
13* end;

How to run a EXECUTE IMMEDIATE statement in a Interactive Report
Hello all!!
I need to make a dinamic construction of a query to execute in a Interactive Report, but the Region Source only allows simple SELECT statements. There is any way to run a EXECUTE IMMEDIATE statement in a Interactive Report Region Source?
Regards Pedro.Thank you Andy for your reply.
I have been testing for a while the use of a collection in the interactive report but i am unable to load data in the interactive report.
I created the collection successfully in the SQL Commands with the code:
declare
v_sql varchar2(32000);
begin
v_sql:='select ename, job from emp';
APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY('coleccao_emp',v_sql,'NO' );
end;
I tested successfully the creation of the collection with the query:
SELECT c001, c002
FROM APEX_collections
WHERE collection_name = 'COLECCAO_EMP'
My problem is: the data of the collection are returned in the SQL Commands but when i run the query statament in an interactive report, report or even a Pl/Sql region in my application the data aren't displayed, only the message (No data found).
Can someone explain why, besides the collection is populated the interactive can not print the results.
Regards Pedro.
