EXECUTE IMMEDIATE with DDL
I'm trying to write a script that will perform the synchronization between two databases, sequence numbers. The only way I know to update the nextval is to change the INCREMENT value, take the nextval, then together, the return to 1 INCREMENT value. If there is an easier way, I'd be interested to hear about it too.However, my current problem is the following. Once I determine dynamically what should be the value to INCREMENT BY, I have run this...
{color: #808080} declare {color}
{color: #808080} v_idDiff number: = 1; {color}
{color: #808080} begin {color}
{color: #808080} run immediately "ALTER SEQUENCE SPHRSBILLING. WORK_UNIT_ID INCREMENT BY: 1 MINVALUE MAXVALUE 999999999999999999999999999 NOCACHE NOCYCLE ALL 0'{color}
{color: #808080} using v_idDiff;
{color} {color: #999999} {color: #808080} end; {color}
{color}
And I get this...
{color: #999999} {color: #808080} ORA-01722: invalid number
ORA-06512: at line 5
{color}
{color} If I simplify things for tests and only try to run this...
{color: #808080} run immediately "ALTER SEQUENCE SPHRSBILLING. WORK_UNIT_ID INCREMENT OF 100 MINVALUE MAXVALUE 999999999999999999999999999 NOCACHE NOCYCLE ALL 0';
{color}
Can I get this...
{color: #808080} ORA-06550: line 1, column 17:
PLS-00103: encountered the symbol "ALTER SEQUENCE SPHRSBILLING. WORK_UNIT_ID INCREASE OF 100 DIGRAPH"when expecting one of the following values:
{color}
{color: #808080}: =. ( @ % ;
The symbol ': = ' was replaced by 'ALTER SEQUENCE SPHRSBILLING. WORK_UNIT_ID INCREASE OF 100 MINVAL' to continue.
{color}
{color: #000000} If I run the ALTAR without being in an EXECUTE IMMEDIATE then it works fine. Ideally, I would like to just pass v_idDiff as a parameter in the ALTAR without the EXECUTE IMMEDIATE, but it does not seem to allow this.
Can someone help me?
Thank you

How to run execute immediate with variables
Hi friends,
How to run execute immediate with variables in v_stmt below?
I don't know how to declare value I have here.
Regds,Set serveroutput on; DECLARE i VARCHAR (20); v_stmt VARCHAR2 (100); CURSOR c IS SELECT sqlid FROM temp1; BEGIN OPEN c; LOOP FETCH c INTO i; EXIT WHEN c%NOTFOUND; DBMS_OUTPUT.put_line (i); v_stmt := 'select * from table(dbms_xplan.display_cursor('&i',null))' execute immediate v_stmt; END LOOP; CLOSE c; END; /
Kunwar.You must first use a variable binding (named ': v' in the SQL statement in my example):
set serveroutput on; DECLARE i VARCHAR (20); v_stmt VARCHAR2 (100); CURSOR c IS -- modified for a quick test SELECT sql_id FROM v$sql where child_number > 2; BEGIN OPEN c; LOOP FETCH c INTO i; EXIT WHEN c%NOTFOUND; DBMS_OUTPUT.put_line (i); v_stmt := 'select * from table(dbms_xplan.display_cursor(:v,null))'; execute immediate v_stmt using i; END LOOP; CLOSE c; END; /
However because your SELECT statement returns multiple lines, you need to adapt your code to process all rows returned (as already suggested in first response to your message).
Instead of using the PL/SQL, I recommend you to generate a SQL file using only SQL, and then run the generated SQL file.
For example:spool edx.sql set serveroutput on declare v_stmt varchar2(100); v_q char(1):=''''; begin dbms_output.put_line('spool edx.log'); for s in (select sql_id from v$sql where child_number >2) loop dbms_output.put_line('select * from table(dbms_xplan.display_cursor(' || v_q || s.sql_id || v_q || ',null));'); end loop; dbms_output.put_line('exit'); end; / spool of
This generates a file similar to:
spool edx.log select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null)); select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null)); select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null)); select * from table(dbms_xplan.display_cursor('fsbqktj5vw6n9',null)); select * from table(dbms_xplan.display_cursor('6q42j0018w7t8',null)); select * from table(dbms_xplan.display_cursor('a5mmhrrnpwjsc',null)); select * from table(dbms_xplan.display_cursor('3c1kubcdjnppq',null)); select * from table(dbms_xplan.display_cursor('3c1kubcdjnppq',null)); select * from table(dbms_xplan.display_cursor('9gkq7rruycsjp',null)); select * from table(dbms_xplan.display_cursor('f0wj261bm8snd',null)); select * from table(dbms_xplan.display_cursor('ab3swhv5g138y',null)); select * from table(dbms_xplan.display_cursor('6vgvyh4xw9c5g',null)); select * from table(dbms_xplan.display_cursor('ak5crjygnpk60',null)); select * from table(dbms_xplan.display_cursor('9p6bq1v54k13j',null)); select * from table(dbms_xplan.display_cursor('19x1189chq3xd',null)); select * from table(dbms_xplan.display_cursor('7sx5p1ug5ag12',null)); select * from table(dbms_xplan.display_cursor('730vdzhng6m6g',null)); select * from table(dbms_xplan.display_cursor('730vdzhng6m6g',null)); select * from table(dbms_xplan.display_cursor('0v3dvmc22qnam',null)); select * from table(dbms_xplan.display_cursor('0v3dvmc22qnam',null)); select * from table(dbms_xplan.display_cursor('a1zv6wju3ftgv',null)); select * from table(dbms_xplan.display_cursor('7ng34ruy5awxq',null)); select * from table(dbms_xplan.display_cursor('7ng34ruy5awxq',null)); select * from table(dbms_xplan.display_cursor('b2gnxm5z6r51n',null)); select * from table(dbms_xplan.display_cursor('b2gnxm5z6r51n',null)); select * from table(dbms_xplan.display_cursor('g4gp07gt2z920',null)); select * from table(dbms_xplan.display_cursor('1gu8t96d0bdmu',null)); select * from table(dbms_xplan.display_cursor('g00cj285jmgsw',null)); select * from table(dbms_xplan.display_cursor('g00cj285jmgsw',null)); select * from table(dbms_xplan.display_cursor('g00cj285jmgsw',null)); select * from table(dbms_xplan.display_cursor('bn4b3vjw2mj3u',null)); select * from table(dbms_xplan.display_cursor('38243c4tqrkxm',null)); select * from table(dbms_xplan.display_cursor('2abjfnvy5rkyg',null)); select * from table(dbms_xplan.display_cursor('350f5yrnnmshs',null)); select * from table(dbms_xplan.display_cursor('350f5yrnnmshs',null)); select * from table(dbms_xplan.display_cursor('3s1yukp05bzg6',null)); select * from table(dbms_xplan.display_cursor('3s1yukp05bzg6',null)); select * from table(dbms_xplan.display_cursor('1tgukkrqj3zhw',null)); exit PL/SQL procedure successfully completed.

Execute Immediate with DOF and TABLE() - error ORA-22905
Hello
I have a problem trying to use a user defined the Type of the Table in a statement Execute Immediate containing a CREATE TABLE statement.
Is there no work around for this problem?
The actual code for the SELECT * OF TABLE(:T) is dynamic and slow. That's why I try to avoid to create/fill the table in two steps (as does with MY_TABLE1). Also, in this case, I can't use SELECT * but must specify all the columns (amount variable and over 100 columns).
CREATE TYPE MY_TABLE_TYPE AS TABLE OF VARCHAR2(30); / DECLARE MT MY_TABLE_TYPE; BEGIN SELECT * BULK COLLECT INTO MT FROM DUAL; -- Two steps EXECUTE IMMEDIATE 'CREATE TABLE MY_TABLE1 (A VARCHAR2(30))'; EXECUTE IMMEDIATE 'INSERT INTO MY_TABLE1 SELECT * FROM TABLE(:T)' USING MT; -- OK -- One step EXECUTE IMMEDIATE 'CREATE TABLE MY_TABLE2 AS SELECT * FROM TABLE(:T)' USING MT; -- ERROR ORA-22905 END; /

use of execute immediate with variables
Hello
I want to update a table with immediate execution, but I need to use the variable to run immediately. I typed a code, but the code below does not work and I m getting the error ORA-00936. Something wrong with this code?
WHILE v_acu_payment_amount > 0
LOOP
BEGIN
SELECT emplid, amount_past_due
IN v_emplid, v_vade_tutari
OF vade_temp
WHERE the sira = v_sirano AND emplid IN (r1.emplid);
END;
v_acu_payment_amount: = v_acu_payment_amount - v_vade_tutari;
Dbms_output.put_line ('paymentamount2' | v_acu_payment_amount);
IF v_acu_payment_amount > 0
THEN
EXECUTE IMMEDIATE "update vade_temp set AMOUNT_PAST_DUE = to_number('||) 0
|| ') where sira = to_number (')
|| v_sirano
|| ')';
ON THE OTHER
Temp: = v_acu_payment_amount * (-1);
Dbms_output.put_line (temp);
EXECUTE IMMEDIATE "update vade_temp set AMOUNT_PAST_DUE = to_number (')"
|| Temp
|| ') where sira = to_number (')
|| v_sirano
|| ')';
END IF;
COMMIT;
v_sirano: = v_sirano + 1;
END LOOP;
Kind regards
Gunce
In addition, you have no dynamic SQL for this
[code]
WHILE v_acu_payment_amount > 0
LOOP
BEGIN
SELECT emplid, amount_past_due
IN v_emplid, v_vade_tutari
OF vade_temp
WHERE the sira = v_sirano AND emplid IN (r1.emplid);
END;
v_acu_payment_amount: = v_acu_payment_amount - v_vade_tutari;
Dbms_output.put_line ('paymentamount2' | v_acu_payment_amount);
IF v_acu_payment_amount > 0
THEN
UPDATE vade_temp
SET amount_past_due = 0
WHERE the sira = v_sirano;
ON THE OTHER
Temp: = v_acu_payment_amount * (-1);
Dbms_output.put_line (temp);
UPDATE vade_temp
SET AMOUNT_PAST_DUE = temp
where sira = v_sirano;
END IF;
COMMIT;
v_sirano: = v_sirano + 1;
END LOOP;
[/ code]
But if you need dynamic sql statements, then you should use bind variables as
...
EXECUTE IMMEDIATE "UPDATE vade_temp SET amount_past_due =: b1 WHERE sira =: b2' using 0, v_sirano;"
...

Use of EXECUTE IMMEDIATE with XML
Database version: 10.2.0.3.0 - 64bi
Hi all
I have an xml that is stored in a table, xmltype column.
I target insert tables including column names and xml nodes are the same.
using the table of all_tab_columns I will generate columns must be passed to xmltable.
all these data, I'll store them in variables and finally proceed to xmltable as below
I just want to know using execute immediate is good to use XML?
SQL_STMT: = 'insert'. table_name | ' ( '|| V_COLUMN_NAME |') ' ;
SQL_STMT: = SQL_STMT | ' SELECT '. V_XTAB_COLUMN_NAME |

RubyHi Ruby,
I just want to know using execute immediate is good to use XML?
Sorry, but this question does not make much sense.
Whether or not dynamic SQL means XML is not relevant, the statement will end up as a cursor in the shared pool independently and be executed or retrieved as any other.If I were you, I'd be worried on the statement do not use bind variables, or the need for dynamic SQL in the first place.
Why should you use dynamic SQL?
If it's laziness, because there are a lot of columns to write down, then it is a bad reason. -

a few notes.
1. to_date(t2.time_id,'dd-mon-yyyy')
New York T2.Time_ID Cis the varchar2 data type that contains values to JJ-me-YYYY format?
And if, in which language is used for the names of the months? Conversions are point impossible to solve in reasonable time limits without logging of dml errors and unique failure on charges of staging nightly!

3. validation
Not required because the DDL commands commit implied.
In general I recommend you write commit clauses only in calling script rather than in the code unless it connects with an autonomous transaction.
You end up with a lot of validation of code here and there and you don't know where it is and where it isn't. That is, your process may have more than one appeal process and commit the middle of the process, it is not atomic processes.
Here's the demo although I recommend also using the static table and truncate to efficiency. ETG is good choice for the purpose of maintenance table.

I need to use the forall with EXECUTE IMMEDIATE statement and the content of string inside EXECUTE IMMEDIATE is a SELECT instead of the usual DML statement.
Objective: In this SELECT statement, I'll be passing of data using the "USING" clause in FORALL statement
When I try to use it, am getting error found "no DATA".
Please advice if I use FORALL and EXECUTE IMMEDIATE on a SELECT statement?
I can share the scenario...

Problem with bind in Execute Immediate
Hi all
Scenario 1:
It works very well.
Scenario 2:DECLARE V VARCHAR2(20) := ':X'; X VARCHAR2(20) := 'Hello World'; RES VARCHAR2(20); QRY VARCHAR2(100); BEGIN QRY := 'SELECT '||V||' FROM DUAL'; EXECUTE IMMEDIATE QRY INTO RES USING X; DBMS_OUTPUT.PUT_LINE(RES); END;

I could do to make it works very well for both scenarios with small changes in the code?My code can't handle scenario 2.
You can change to sth as follows:

dml execution 2 statements at a time with the help of execute immediate
I would like to run 2 DML statements at a time with the help of execute immediate usefulness,.
ex:
update employee set ename = 'Chantal' where eno = 123;
Update dept set dname = 'IT' where dno = 345;
I want the two statement to execute at a time, but I don't want to use any loop as well.
Thanks in advanceYou can use:
execute immediate 'begin update employee set ename='jagadeesh' where eno=123; update dept set dname='IT' where dno=345; end;';
Although updates will always run one after the other.
If you want the simultaneous treatment, then you need to use DBMS_JOB and DBMS_SCHEDULER to plan both work to run to run each of the statements independently.

EXECUTE IMMEDIATE or DBMS_UTILITY. EXEC_DDL_STATEMENT
Hello
I recently became aware of DBMS_UTILITY. EXEC_DDL_STATEMENT and I was wondering if it works in pretty much the same way as EXECUTE IMMEDIATE. I'm guessing that EXECUtE IMMEDIATE offers more flexibility when putting together the command you want to run, but you are the only real difference? All opinions accepted with gratitude,
Kind regards
Kevin.This isn't an exact answer to your question, but it may be useful.
Execute Immediate is the approach privileged 9i or higher. If you decide which to use, go with EXECUTE IMMEDIATE. You never know when the other dynamic SQL methods will be deprecated. In addition, EXECUTE IMMEDIATE has also been optimized (and will continue to be optimized), so you can usually expect better performance during use.
The exact differences between EXECUTE IMMEDIATE and DBMS_UTILITY. EXEC_DDL_STATEMENT go, I can't give you an exact answer. (Also the fact that DBMS_UTILITY. EXEC_DDL_STATEMENT DDL is, of course).
You may or may not find this article helpful: http://okjsp.pe.kr/seq/9789. He did a good job to compare the differences between EXECUTE IMMEDIATE and another way inherited to the dynamic SQL statements (DBMS_SQL. RUN)

Maximum size of EXECUTE IMMEDIATE
Hellou everyone,
I would like to ask if there is a way how to run the dynamic SQL CREATE or VIEW of REPLACE command more than 32 KB of wholesale. Because the EXECUTE IMMEDIATE statement can run up to 32 k (greater length of variable plsql chain) chain
Is there a way how children Ridge or replace the command?
Or I need to revrite using DBMS_SQL.
Thank you.
(a) WHY? If you want to dynamically create views? This is not recommended because your application/database should be designed at the time of the design, not running.
(b) If you are on 11 g, you can use the CLOB datatype with immediate execution, so there is no 32 K limit.
(c) If you are before 11 g you need to update, but if you can't then the following example is how you do it using DBMS_SQL.
SQL > declare
2 v_large_sql clob.
3 v_num number: = 0;
number of v_upperbound 4;
5 v_sql dbms_sql.varchar2s;

12 v_large_sql: = v_large_sql | v_join_sql | "select" the number of this line is: ' | TO_CHAR (v_num, 'fm0999999') | " "as col1 from dual;"
13 v_join_sql: = "union all";
14 v_num: = v_num + 1;
15 exit when dbms_lob.getlength (v_large_sql) > 40000 or v_num > 800;
16 end loop;
17 dbms_output.put_line (' length :'||) DBMS_LOB. GetLength (v_large_sql));
18 dbms_output.put_line ('Num :'|| v_num);
19-
20. now divide this big SQL statement into pieces of 256 characters and put in table VARCHAR2S
21 v_upperbound: = ceil ((v_large_sql) dbms_lob.getlength / 256);
22 because me at 1.v_upperbound
23 loop
24 v_sql (i): = dbms_lob.substr (v_large_sql
25, 256 - amount
26, ((i-1) * 256) + 1 - offset
27 );
28 end of loop;
29-
30. now analyze and execute the SQL statement
31 v_cur: = dbms_sql.open_cursor;
32 dbms_sql.parse (v_cur, v_sql, 1, v_upperbound, dbms_sql.native, false);
33 v_ret: = dbms_sql.execute (v_cur);
34 dbms_output.put_line ("' view created");
35 dbms_sql.close_cursor (v_cur);
36 end;

Create a temporary table using EXECUTE IMMEDIATE
Hello
I need to create a report more complex which must have three different queries. I use a determined IF clause that the query that uses the report, according to the parameters.
I want to write the output to a csv file, so I created a PROCEDURE.
The first package of the procedure has the three SQL and the IF clause in order to determine the query that the report uses and stores the query code in a variable (v_sql), which is passed to the PROCEDURE that needs to write to the output of the report.
I tried to create a table with data from the request in order to make a LOOP and exit, something like this:
WRITE_FILE (errBUFF of the PROCEDURE OUT VARCHAR2, retCODE OUT VARCHAR2, v_sql IN VARCHAR2) IS
Contor NUMBER; BEGIN
EXECUTE IMMEDIATE v_sql; SLIDE G IS Select * from XXROR_REG_MF_TBL; -- -initialization -- retCode: = 0; errBUFF: = NULL; Contor: = 0; -- -cursor -- FOR X IN G LOOP APPS. FND_FILE. PUT_LINE) APPS. FND_FILE. OUTPUT, ....) I should mention that v_sql is something like:
CREATE GLOBAL TEMPORARY TABLE ACEs (SELECT * of the double);
I can't really do that, so I was wondering if you have any suggestions
Thank you
Claudiu
Hello
I don't think you need a table at all. You can set the cursor based on the SQL passed as parameter
