EXECUTE IMMEDIATE stmt

I am using oracle 10G XE.
When I have the following, it works fine..
========================================
FOR report_c IN report_cur LOOP
FOR i in 1 .. 62 loop
INSERT INTO trip_stop (sc_v, r_id, b_id,
code_id, terminal, seq_num, bs_id, flag, note_id, eta_string)
VALUES (report_c.sc_v, report_c.r_id, report_c.b_id,
report_c.code_id, report_c.terminal, i , report_c.st_id1,
report_c.flag1, report_c.note1, report_c.eta1);
COMMIT;
END LOOP;
END LOOP;
========================================
I need to use a dynamic sql to change the column name
i.e.: from id1 to id2 then to id3, etc..
I need to repeat this 62 times.. So I tried to use the following, but I got error:
ORA-00984: column not allowed
Any idea??? Any suggestion??
Thanks
========================================
FOR report_c IN report_cur LOOP
FOR i in 1 .. 62 loop
stmt:= ' INSERT INTO trip_stop ' ||
' (sc_v, r_id, b_id, ' ||
' code_id, terminal, ' ||
' seq_num, bs_id, flag, note_id, eta_string) ' ||
' VALUES (report_c.sc_v, report_c.r_id, report_c.b_id, ' ||
' report_c.code_id, report_c.terminal, ' ||
i ||','|| c_st_id||','|| c_flag||','|| c_note||','|| c_eta|| ' ||);' ;
i ||', report_c.st_id' || i || ', report_c.flag' || i||', report_c.note' || i||', report_c.eta' || i||');' ;
EXECUTE IMMEDIATE stmt;
END LOOP;
END LOOP;

I would suggest "unpivoting" that table by turning each row in the source table into 62 rows - that way you can insert into/select from and do this in one insert statement with no procedural or dynamic code at all.
Here's an example going 1-2 instead of 1-62:
sql>select * from t;
SC_V R_ID B_ID ST_ID1 FLAG1 ETA1 ST_ID2 FLAG2 ETA2
    0   123 1111    101     1 1001    102     0 1002

Failure of EXECUTE IMMEDIATE when in a stored procedure

Hello,
this concerns behaviour observed in Oracle 10g on Windows.
As user "system", I execute from the command line the following:
SQL> select COUNT(1) from sys.dba_sequences;
COUNT(1)
645
Again I try the same thing from the command line:
SQL> declare
2 CNT INTEGER:=0;
3 STMT VARCHAR2(300);
4 BEGIN
5 STMT:='select COUNT(1) from SYS.DBA_SEQUENCES';
6 EXECUTE IMMEDIATE STMT INTO CNT;
7 dbms_output.put_line('CNT='||CNT);
8 end;
9 /
CNT=645
So far so good, clearly this table exists and I have sufficient privileges to access SYS.DBA_SEQUENCES as user system.
However, if I put this in a stored procedure in a script TEST_SEQ.sql and then execute, I get ORA-00942:
1. Create or replace Procedure TEST_A1
2. IS
3. CNT INTEGER:=0;
4. STMT VARCHAR2(300);
5.
6. BEGIN
7. STMT:='select COUNT(1) from SYS.DBA_SEQUENCES';
8. EXECUTE IMMEDIATE STMT INTO CNT;
9. dbms_output.put_line('CNT='||CNT);
10. END;
SQL> @ TEST_SEQ.sql
SQL> exec TEST_A1;
ORA-00942: Table or view does not exist
ORA-06512: At "SYSTEM.TEST_A1", line 8
ORA-06512: At line 1
Why now does this table not seem to exist when accessed from a stored procedure?

/Even though I provided this, static SQL is always faster than PL/SQL because there is no context switch.
An alternative to the above is to write all static SQLs into a script and run it.
However, if you don't know which tables and column to update before hand, and the update depends on user inputs (e.g. from a JSP), then Java can call a stored procedure to perform the update.

Execute immediate and "in" operator

Hello!
I want to pass varchar2 type argument to my procedure in format '1,2,3' where 1,2 and 3 are some IDs.
And then, in procedure I write:
stmt := 'select avg(PRICE) from ORDERS where ORDER_ID in (:Ids)';
execute immediate stmt into APrice using ARGUMENT;
I undersand, that this is incorrect, because where clause in executable query is
"where ORDER_ID in ('1,2,3')" but not "where ORDER_ID in (1,2,3)".
Is there any easy way how to solve such a problem?
Maybe I should use other argument type?

user10304317 wrote:

stmt := 'select avg(PRICE) from ORDERS where ORDER_ID in (' || ARGUMENT || ')';
execute immediate stmt into APrice;However, it will produce as many sql in shared pool as you will have different ARGUMENT values and each of them will do a hard parse. Or you could use collection and then you do not need dynamic sql (unless select list and/or rest of where clause is dynamic):

Unable to INSERT PL/SQL record with EXECUTE IMMEDIATE

Hi All,
I am selecting data from a source table and after some modification inserting into a target table. Source and target table name are available at run time. You can say only source table structure is fixed.
I have crated a pl/sql table of type source record and inserting record by record in target table using execute immediate. But I am not able to write
EXECUTE IMMEDIATE string USING pl_sql_table(index); and getting error as
PLS-00457: expressions have to be of SQL types
Please see the part of code below. Is it possible to use FORALL with dynamic sql like
FORALL pl_sql_table.FIRST .. pl_sql_table.COUNT
EXECUTE IMMEDIATE .... pl_sql_table(j); -- Like this.
Please suggest why I am not able to write record here. I also want to replace 'INSERT in a loop' with a single INSERT statement out of the loop, to upload whole pl_sql table into target table in one go.
Thanks,
Ravi

You cannot bind PL/SQL record types to dynamic SQL.
Possibly you could work around this by declaring the INDEX-BY table of records at package specification level, e.g.

How to display result of execute immediate on sql prompt

CREATE or replace PROCEDURE select_rows (
table_name IN VARCHAR2,

AS
where_clause VARCHAR2(100) := ' WHERE ' || condition;
BEGIN
IF condition IS NULL THEN where_clause := NULL; END IF;
EXECUTE IMMEDIATE 'select * FROM ' || table_name || where_clause;

my procedure is successfully created.
my problem is how to get select stmt output at screen (sql prompt)
or how to spool the output in a file.
plz. help me. I am learning oracle .
thanx in adv.

You could use refcursors. Example :

Problem while executing procedure thru Shell script (EXECUTE IMMEDIATE)

Hi All,
I have created a procedure where i am passing column name, tablename and business date. The procedure gets last 5 business date excluding Saturday and sunday based on business date.
i am using EXECUTE IMMEDIATE statement in the procedure, where i am replacing the column name, table name, and business date & then executing this statement.
stmt := 'select count(1) FROM '||tblname||' where trunc('||date_column||')= :1';
EXECUTE IMMEDIATE l_stmt into tbl_count using to_char(in_date, 'DD-MON-YYYY') ;
It will give me the count of all 5 days for a particular dates. When i run the procedure in SQL*Plus/TOAD, it gives me desired result. When i run this in UNIX shell script, it runs fine but at end gives following error:
SP-xxx: Bind varaible not declared.
Can someone tell me where might be the problem?

Hello, if you could put a {noformat}{noformat} before and after your snippets of code please, it makes it much easier to decipher.
You have:EXECUTE IMMEDIATE l_stmt into tbl_count using to_char(in_date, 'DD-MON-YYYY') ;
Where it should be:EXECUTE IMMEDIATE l_stmt into tbl_count using TRUNC(in_date) ;
Additionally, you do not need the SQL script, you could simply have:sqlplus -S $ORA_UID/$ORA_PWD@$DSQuery <<EOF >>${TMP_DIR}/report.log 2>&1
whenever sqlerror exit failure
whenever oserror exit failure
set serveroutput on;
set pages 0;
set feed off;
exec return_date ('20090515','STIFAPACDTR','ASOFD','n');
print;
quit
EOF
if [[ $? -ne 0 ]]
then
echo "sqlplus did not run successfully,verify"
echo "For errors please check ${TMP_DIR}/report.log file\n Exiting..."
else
echo "$0 script executed successfully"
fi
exit $?
You don't need any of this:if /usr/xpg4/bin/grep -e 'ORA-' -e '^ERROR at' -e 'unknown command' ${TMP_DIR}/report.log
then
print "sqlplus did not run successfully,verify"
print "For errors please check ${TMP_DIR}/report.log file\n Exiting..."
exit 1
fi
if [http:// -s ${TMP_DIR}/report.log ]
then
print "`echo $0 script executed successfully"
grep -v '^$'${TMP_DIR}/report.log > ${TMP_DIR}/report.csv
else
print "${TMP_DIR}/report.log file not generated, verify, \n exiting"
exit 1
fi
outFLAG="n"
done
I'm not sure that that will fix your problem here, but can you try again with those changes.

Error while insert data using execute immediate in dynamic table in oracle

887684 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.

Strange Case on Security Rights and Dynamic SQL (Execute Immediate)

Hi friends, (forgive me if I write with wrong grammar and sentence, I not used English for daily)
I got a weird trouble yesterday.
I created a package (we can called it X, OK!?) which containing Execute Immediate Statement, that function to delete a table (we can called it Y).
Several days ago, it's worked, but yesterday it wasn't. Last things happened before was recreate those table, and regrant to a role which including user account that execute package X.
Error Msg shown is ORA-00942 : Table or view does not exist. After rechecked and rechecked, I found nothing that could trigger that error, I used DBMS_OUTPUT.PUT_LINE to debug and show what statement resulted and executed, I cut and paste, and it's worked. I created anonymous PL/SQL Block, and wrote it and executed it, and worked.
Finally, today, We Grant explicitly those table to user account Y, not via Role, ... and it's work. Interesting thing I think :P
And, I revoke, execute package and run. I think, there's something about Oracle he..he.. :D .
Can somebody help me and explain me the reason of that strange symptomp? and right solution? I must know it, because several days again, it's launched / install.
TIA

Execute immediate and dynamic sql

Dear all;
Just curious....Why do developers still use dynamic sql..and execute immediate, because I always thought dynamic sql were bads and the use of execute immediate as well...
or am I missing something...

There are no 'bad' things and 'good' things.
There are 'correctly used' and 'incorrectly used' features.
It depends what you want to do.
One simple example: Oracle 11.2 - you write a package that fetches data from range interval partitioned table (a new partition is created automatically every day when new key values are inserted). If you use static SQL then whenever Oracle creates a new partition then your package gets invalidated and has to be compiled. If your package is heavily used (by many sessions running in parallel) then you may get this:
ORA-04068: existing state of packages has been discarded
ORA-04061: existing state of package body "PACKAGE.XXXXX" has been invalidated
ORA-06508: PL/SQL: could not find program unit being called: "PACKAGE.XXXXX" Nice, isn't it?
You can avoid this kind of problems by simply using dynamic SQL. You break dependency with the table and your package is not invalidated when new partition is created.

[Solved] Reference apex_application.g_fXX in "execute immediate" statement

Hi!
I created a dynamically generated tabular form - the number of columns is not known in advanced. Each cell of the form is a text item generated with apex_item.text().
I want to write an after-submit process that saves the values from the form into a database table. In this process I already know how many columns there are in the report so I want to do the following:
--for each row...
for i in 1..apex_application.g_f01.count loop
-- and for each column in that row (number of columns is in v_col_count)
for j in 1..v_col_count loop
    -- get the value of text item
    v_query := 'select apex_application.g_f0' || j || '(' || i || ')' || ' from dual';
    execute immediate v_query into v_value;
    -- now do some DML with v_value
end loop;
end loop;The problem is that I get an error: ORA-06553: PLS-221: 'G_Fxx' is not a procedure or is undefined where xx is the number from the generated query.
My question is - am I doing something wrong or is is just not possible to reference apex_application.g_fxx in "execute immediate"? Will I have to manually check for all 50 possibilites of apex_application.g_fxx? Is there another way?
TIA,
Jure

Well now I know what was wrong and what you were trying to tell me - apex_application.g_fxx is not visible in "plain" SQL. And now I also have a solution to this problem. The point is to wrap the select statement with begin - end block so that the statement is rendered as pl/sql:
--for each row...
for i in 1..apex_application.g_f01.count loop
-- and for each column in that row (number of columns is in v_col_count)
for j in 1..v_col_count loop
    -- get the value of text item
    v_query := 'begin select apex_application.g_f0' || j || '(:i)' || ' into :x from dual; end;';
    execute immediate v_query using i, out v_value;
    -- now do some DML with v_value
end loop;
end loop;This works great :).
Jure

How can i have '&' in EXECUTE IMMEDIATE statement?

I have PL/SQL procedure, where i will be inserting data to a table. Data which i am inserting is having a '&' value in it. If i use the below statement for insert then sqlplus is prompting for the value '&' like a substitution value while compile this procedure.
EXECUTE IMMEDIATE 'INSERT INTO TABLE_TEST VALUES (:1,:2)' USING 'root/direct/&text', SYSDATE;If i replace the '&' by assigning this value to VARCHAR field then it is working properly. But when i populate an xml from this table using DBMS.XMLGEN, then the value '&' is not entity escaped in the XML which is normally replaced with '&' in XML.
Please help.

Vel wrote:
i can't go by both ways because i am using '&' in various files to get some values. Also in this package i am using the '&' to get another substitution variable. Is there any other workaround possible?I prefer not to mess with server-side SQL and PL/SQL code to fix, or work around, a problem on the client-side. Not a very sensible thing IMO.
In such a case as you've described, I would set the substitution character to a character that I'm not using in server-side code. I have done this a couple of times in the past for db create and installation scripts. Oracle uses the same approach for their Apex installation scripts.
I think Oracle uses the +#+ character for their Apex install scripts. E.g.
set define '#'I think I used the tilde (char <i>~</i>) at a stage as substitution char as it is very seldom used in PL/SQL and SQL code.
The bottom line is that you will need to change your code. Set define off and on where needed to ensure substitution only happens where needed. Set the substitution char to a different char and update your substitution variables. Or hack your server-side code (as suggested above) and use the char() function instead.

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.
Thanks

Hi 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
