Insertion Using Execute Immediate

How to use Execute Immedaite in Inserting while with dynamic table name. Is that possible or we can use only the dynamic values.
Execute Immediate "Insert Into " || DYNAMIC TABLE NAME || "Values"
Using (Value_1, Value 2, Value3).

Why would tables be added later? Are they storing the same structure of data? If so you should be using a single table possibly with partitioning.
If they are of different structures then you should have one procedure for each structure, otherwise you're going down the Bad Design ^tm^ route. A single procedure should perform a single task. Trying to make generic code is generally considered a lazy design and often leads to performance issues and difficult to track bugs.

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...

t_sub_mark is a class of type sub_mark

begin
EXECUTE IMMEDIATE ' create table '||op_sample||'

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.

Edited by: user9213000 on 24-Jan-2013 07:38The standard advice when (ab)using EXECUTE IMMEDIATE is to compose the SQL statement in a single VARCHAR2 variable
Then print the variable before passing it to EXECUTE IMMEDIATE.
COPY the statement & PASTE into sqlplus to validate its correctness.

Using EXECUTE IMMEDIATE with XML

Database version : 10.2.0.3.0 - 64bi
Hi All,
I have a xml which is stored in a table, xmltype column.
i have target insert tables whose column names and xml nodes are same.
using all_tab_columns table i will generate columns to be passed to xmltable.
all these data i will store in variables and finally pass to xmltable as below
just want to know using execute immediate is good to use in XML?
SQL_STMT := 'insert into '||table_name|| ' ( '||V_COLUMN_NAME||')';
SQL_STMT := SQL_STMT ||' SELECT ' ||V_XTAB_COLUMN_NAME ||
' FROM TO_XML,
XMLTABLE(' ||v_xpath||
'PASSING XML_VALUE
columns ' || V_COLUMNS_DATA_TYPE
||') XTAB
WHERE Seq_NO = ' || P_SEQUENCE_NO ;
EXECUTE IMMEDIATE SQL_STMT ;
Thanks and Regards,
Rubu

1) is it OK? As I stated above, it can be made to work. It would not be my first choice, but then none of us here know the full details as well as you do so maybe there is a compelling reason to use dynamic SQL.
Here is the documentation for [url http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/executeimmediate_statement.htm#LNPLS01317]EXECUTE IMMEDIATE.
Actually now I finally realize your XML resides in table TO_XML so that means you won't be putting the actual XML into the shared pool via an incorrectly written dynamic SQL statement at least. That is what Odie and I were first concerned about with dynamic SQL usage, that the XML would be hard-coded into your SQL_STMT variable. You are simply changing the columns (in 3 locations). With that setup, you have no need for (nor can use) bind variables. The overall issue of dynamic SQL being slightly slower than static SQL still exists as the SQL statement will first have to be parsed and validated.
A larger issue in terms of performance is how 10.2 handles XMLTypes. If the underlying XML is large, XMLTable performance degrades quickly. Options around this are to parse the XML in PL/SQL or to upgrade to some version of 11 and use SECUREFILE BINARY XML as the underlying storage structure for the TO_XML.XML_VALUE column.

Problem in Update statement using Execute Immediate

Hi All,
I am facing problem in update statement.
I am creating dynamic sql and use "execute immediate" statement to execute a update statement.
But it is not updating any thing there in the table.
I have created a query like :
update_query='Update '|| Table_Name ||' t set t.process_status =''Y'' where t.tid=:A';
Execute immediate update_query using V_Id;
commit;
But it is not updating the table.
I have a question , is execute immediate only does insert and delete?
Thanks

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,
Chris

uhmm, 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.

Using execute immediate creating a table from another

hi friend i wanted to create a table from a select statement in a pl sql procedure. i am using execute immediate but getting problems with it pls can anyone help me.
here is the query i am using
EXECUTE IMMEDIATE 'CREATE TABLE table_name AS (SELECT * FROM a_view WHERE column_name LIKE '%some_string%');
i need to know if this can be done and if yes how. pls help me its bit urgent too. the schema name is same and the privileges are available to create tables too.

Your syntax is wrong.
If you would use a syntax higlighted editor, it would show.
Yout try to execute a string where another string is embedded. Please use two times single quote or use the 'q' function:
This one is correct:
EXECUTE IMMEDIATE 'CREATE TABLE table_name AS (SELECT * FROM a_view WHERE column_name LIKE ''%some_string%'')';
or this one:
EXECUTE IMMEDIATE q'|CREATE TABLE table_name AS (SELECT * FROM a_view WHERE column_name LIKE '%some_string%')|';
good luck

Create temp table using EXECUTE IMMEDIATE

Is there any performance issue in creating globally temp table
using EXECUTE IMMEDIATE or creating globally temp table from
SQL PLUS.
Any response will be greatly appreciated.
null

Anish,
Creating tables is likely to be an expensive operation.
Performance issues can only be considered in comparison to
alternatives.
Alternatives include: PLSQL tables, cursors and/or recoding so
that tmp tables are not required. (One of our consultants reckons
that sqlserver temp tables are usually used to get around
limitations in sqlserver, ie slightly more complicated sql
statements could be used instead of simpler sql and temporary
tables).
I would think creating the temp table once during sqlplus would
be cheaper than creating and deleting it repeatedly at run time.
Note that EXECUTE IMMEDIATE may do an implicit commit (dbms_sql
certainly does). This may be got over my using the PRAGMA
AUTONOMOUS_TRANSACTION; direction which places a
procedure/function in a seperate transaction.

Edited by: xDeviates on Jun 11, 2012 3:13 PM

It looks like you are approaching the problem incorrectly. As I suggested in Dynamic Select, it sounds like you, at most, want a function that returns a SYS_REFCURSOR (it's still not obvious to me why you would even want/ need to resort to dynamic SQL in the first place)
CREATE OR REPLACE FUNCTION get_dynamic_cursor( p_table_name IN VARCHAR2 )
RETURN sys_refcursor
IS
l_rc sys_refcursor;
BEGIN
OPEN l_rc FOR 'SELECT * FROM ' || dbms_assert.sql_object_name( p_table_name );
RETURN l_rc;
END;which you can then call from your application
SQL> variable rc refcursor;
SQL> exec :rc := get_dynamic_cursor( 'EMP' );

Using EXECUTE IMMEDIATE for DML

What benefit is there to use EXECUTE IMMEDIATE for an UPDATE statement like the one below.
EXECUTE IMMEDIATE 'UPDATE mytable SET bonus = v_bonus(i)
                   WHERE empid =:empid AND sal =:sal'
                          USING v_empid(n),v_sal(i);This UPDATE sql is not dynamically created. So is there any performance benefit associated with using
EXECUTE IMMEDIATE for this UPDATE? Can't i just use a normal UPDATE without EXECUTE IMMEDIATE?

Ran these same tests with SQL_Trace turned on, ran the trace files through tkprof and look at what it tells us:

By wrapping the procedure call in a dynamically created anonymous block, you are incurring LOTS of overhead.
What is it that you are trying to simulate.
What are you trying to do?

Using execute immediate in form

hi all
how can I use Execute Immediate In form It give me error but In sql no error
thank you

There are two options.
1. FORMS DDL
2. Call a backend function or procedure which has got EXECUTE_IMMEDIATE in it.
Following procedure can be used to execute the dymanic sql in forms.
Create this procedure in backend.
CREATE OR REPLACE PROCEDURE pr_execute_immediate (p_sql_stmt VARCHAR2) IS
BEGIN
EXECUTE_IMMEDIATE(p_sql_stmt );
END pr_execute_immediate;

Create Partition tables in PL/SQL using Execute Immediate

Hi
I have to create a partiton table in PL/SQL using Execute Immediate. I concat the necessary Create Table syntax into a variable and use Execute Immediate variable name. This gives a error ORA-00900: invalid SQL statement. However if i cut and paste the SQL statement from DBMS_OUTPUT, the table creation goes through without any problem.
What could be the issue. Has anyone face this before please.
I am using 10G DB

Thanks for your reply. It is a big code. I am pasting the part required.
v_sqlstmtout :='CREATE TABLE a_10(MYDATE DATE NOT NULL,ID NUMBER(14) NOT NULL)';
v_sqlstmtout := v_sqlstmtout || ' PARTITION BY RANGE (MYDATE) ';
v_sqlstmtout := v_sqlstmtout || 'SUBPARTITION BY HASH(id) ';
v_sqlstmtout := v_sqlstmtout || 'SUBPARTITION TEMPLATE(';
v_sqlstmtout := v_sqlstmtout || 'SUBPARTITION SP1,SUBPARTITION SP2) ';
v_sqlstmtout := v_sqlstmtout || '(PARTITION mth_dummy VALUES LESS THAN ';
v_sqlstmtout := v_sqlstmtout || '('||V_SQLSTMT3||')' || v_sqlstmt||')';
EXECUTE IMMEDIATE ''''||v_sqlstmtout||'''';
variables are substituted through data from different tables.
The output looks like the following
CREATE TABLE a_10(MYDATE DATE NOT NULL,ID NUMBER(14) NOT NULL)
PARTITION BY RANGE (mydate) SUBPARTITION BY HASH(id) SUBPARTITION
TEMPLATE(SUBPARTITION SP1,SUBPARTITION SP2) (PARTITION mth_dummy VALUES
LESS THAN ('01-MAY-2006'), PARTITION mth_JAN2007 VALUES LESS THAN
('01-FEB-2007'))
The above is the output from DBMS_OUTPUT. If i run this statement the table is created. Please help..
