Doubt & Error Using Dynamic SQL

Hello,
According to oracle documentation for Dynamic SQL using ' Method 2 ' ... which says ...
Method 2
This method lets your program accept or build a dynamic SQL statement, then process it using the PREPARE and EXECUTE commands. The SQL statement must not be a query. The number of placeholders for input host variables and the datatypes of the input host variables must be known at precompile time. For example, the following host strings fall into this category:
'INSERT INTO EMP (ENAME, JOB) VALUES (:emp_name, :job_title)'
'DELETE FROM EMP WHERE EMPNO = :emp_number'
Now for trying this method i created a procedure .. named .. 'aj_proc_1'
CREATE OR REPLACE PROCEDURE aj_proc_1(p_id IN NUMBER)
IS
BEGIN
EXECUTE IMMEDIATE 'delete from aj_test_1 where id = :p_id';
END aj_proc_1;
And the table which m using in this procedure is ...
SQL> select * from aj_test_1;
ID NAME
1 aijaz
2 melwin
3 aasim
4 satish
5 ashok
So now whn m calling this Procedure & wanted to delete the record with id '2' ... m getting an Error...the way m executing this procedure is ...
SQL> execute aj_proc_1(2);
BEGIN aj_proc_1(2); END;
ERROR at line 1:
ORA-01008: not all variables bound
ORA-06512: at "FA.AJ_PROC_1", line 4
ORA-06512: at line 1
Please Help me .. As i have no idea ..wats goin wrong over here...

Now whats Wrong with this 1 ....
CREATE OR REPLACE PROCEDURE aj_proc_1(p_id IN NUMBER)
IS
     val_name varchar2(34);
BEGIN
     EXECUTE IMMEDIATE 'select name into '||val_name||' from aj_test_1 where id = :p_id'
                    USING p_id ;
          dbms_output.put_line(val_name);
END aj_proc_1;
SQL> exec aj_proc_1(2);
BEGIN aj_proc_1(2); END;
ERROR at line 1:
ORA-00936: missing expression
ORA-06512: at "FA.AJ_PROC_1", line 5
ORA-06512: at line 1

Getting error while using DYNAMIC SQL

Hi Team,
I am Oracle DBA. I have limited knowledge on PL/SQL. I used below PL/SQL code to drop 50 partitons from one of the table.
I used Dynamic SQL EXECUTE IMMEDIATE to drop partions. But error occured. If I commented EXECUTE IMMEDIATE, procedure executed successfully.
Please suggest me, where i did the mistake. Also please suggest for better code than my code. please find below code and error details.

PL/SQL procedure successfully completed.

PL/SQL code runs on the server, inside an Oracle process - thus PL/SQL code cannot dynamically write and display messages to the client. That server process is not connected to any keyboard, mouse or display.
DBMS_OUTPUT can be used. This is a PL/SQL buffer area in that server process that code can write lines of text too. When the server process informs the client that it has completed, the client can now request the contents of the DBMS_OUTPUT buffer and the client can display it on the client device.
This is what set serveroutput on in SQL*Plus does - tell the sqlplus client to request the DBMS_OUTPUT buffer after each Oracle server call made and to display the contents locally.
So to display the SQL command can be done using DBMS_OUTPUT. E.g.
declare
dropPart varchar2(32767);
begin
for c in (select...) loop
    dropPart := 'alter table my_tab drop partition '||c.partition_name';
    --// write the SQL command to DBMS_OUTPUT
    DBMS_OUTPUT.put_line( dropPart );
    --// execute the SQL using a begin..end block in order to catch error
    begin
      execute immediate dropPart;
      DBMS_OUTPUT.put_line( 'command completed successfully' );
    exception when OTHERS then
      DBMS_OUTPUT.put_line( 'command failed with: '||SQLERRM(SQLCODE) );
    end;
end loop;
end;So after this code block has been executed and partitions dropped, sqlplus will display the DBMS_OUTPUT generated by this code block.

ORA-06502:PL/SQL:numeric or value error. Dynamic SQL the only answer??

ORA-06502: PL/SQL: numeric or value error: character string buffer too small.
I have an HTMLDB report that errors with the above message. The query is over 7000 characters long so I'm guessing this is the cause. If I retrieve the query from a query table, replace the variables in the LONG query using PL/SQL and execute using dynamic SQL, are the HTMLDB reporting features the same as if I was using a simple SQL query? Is there a better way? I will need to 'drill-down' from this report so how do I create the links? The only HTMLDB PL/SQL package I can find mentioned in the User's Guide is HTMLDB_PLSQL_JOB.
Cheers, Paul

Hello All,
I have the same problem.
For me it started when i got about 500 rows in the table
on which the LOV is based.
With a lot of trying with substr I managed to find the size of the string which it still accepted, which was 51 characters.
So I thought it was some glitch in the APEX insides, and since I had no time to resolve it further, I went on working.
But I have to resolve it now, because the following mysterious behaviour is occurring:
Every few records added to the base table, the problem occurs again, and I can resolve it by cutting down the string
with one character.
I have now reached 39 characters !?
I am afraid that I will end up with 1 character or even null.
If I switch to Popup list based on LOV there's no problem, and the complete strings are shown.
The maximum length of the string in my basetable is 252, but the data in it now reaches 55 at most.
Any idea welcome!
I did already recreate the master-detail form from scratch, but there the same behaviour.
greetings,
Richard Kloostra

Using Dynamic SQL in Forms

Does anyone know anything about Dynamic SQL not being available in Forms v. 6.0.8.11.3? I trying to use Dynamic SQL for the first time and am having some difficulty. When I try to put my SQL in a function and run it straight into the database through SQLPlus, it works fine, but when trying to compile the code in Forms Builder (in a library), I get compiler errors. Any help would be appreciated...
Thanks!
Vanessa

When I tried to compile the following code in Forms, the compiler error I got was Encountered the symbol "STMT_STR" when expecting one of the following: select. However, when I run it in SQLPlus, it creates the function without any errors.
FUNCTION my_func
return number
is
TYPE DiaryCurTyp IS REF CURSOR;
cur DiaryCurTyp;
stmt_str VARCHAR2(200);
dmonth NUMBER;
dday NUMBER;
BEGIN
stmt_str := 'SELECT dmonth, dday FROM p2_diary
WHERE dmonth = :1';
OPEN cur FOR stmt_str USING '12';
LOOP
FETCH cur INTO dmonth, dday;
EXIT WHEN cur%NOTFOUND;
-- <process data>
END LOOP;
CLOSE cur;
END;

Getting error during Dynamic sql

Hi,
I'm facing issue with dynamic sql.My aim in the following code is to get count from the table, if pattern "xyz" exits for past 5 mins.
I'm getting the following error
ORA-01006: bind variable does not exist
/* *Sample code is/
declare
lv varchar2(10):='xyz';
li_count number :=0;
sql_var varchar2(2000):=null;
begin
sql_var := 'SELECT COUNT(1) FROM wms_trace WHERE LOWER(MSG_TEXT) LIKE LOWER(''%' || ':1' ||'%'') AND create_dt> sysdate - 0.083333/24';
DBMS_OUTPUT.PUT_LINE(sql_var);
EXECUTE IMMEDIATE sql_var into li_count using lv;
DBMS_OUTPUT.PUT_LINE(li_count);
end;
I went for dynamic sql since i could not put my vairable in side , as follow
like lower ('%lv%'). If i put instead of search for "xyz" it will search for variable name itself as "lv"
Thanks in advance for your help
Kannan

You don't need to use dynamic SQL in this case. Try the following (untested):
DECLARE
lv varchar2(10):='xyz';
li_count number :=0;
BEGIN
SELECT COUNT(1) INTO li_count
FROM wms_trace
WHERE LOWER(MSG_TEXT) LIKE '%' || LOWER(lv) || '%'
AND create_dt> sysdate - 0.083333/24
END;

How to Use Dynamic SQL

Can anybody please send me a small program on How to Use Dynamic SQL.
How to execute and run give details.
Thanks

You can certainly use the INTO (and USING) clauses of EXECUTE IMMEDIATE to pass in and return data, i.e.
EXECUTE IMMEDIATE sqlStmt
USING variable1, variable2
INTO output1, output2The more complex the statement, however, the more appropriate DBMS_SQL is. DBMS_SQL also has the potential to allow you to use bind variables rather than reparsing the statement many times.

Delcare Cursor using Dynamic SQL using PL/SQL in Oracle 7.3.4

In Oracle 7.3.4, can I declare a cursor at run time using Dynamic SQL. From the sample code in this website, it seems that Oracle 8 support this function. Please help. Thanks a lot.
If I can do this on Oracle 7.3.4, could you give me some sample codes? Thanks.
Regards,
Raymond

Hi,
Try using the the following code where you can dynamically build the Valid Select stmt. and call that where ever you want.
declare
Type Cur_ref Is Ref Cursor;
C_ref Cur_ref;
V_Str Varchar2(100);
V_Name Varchar2(100);
Begin
V_Str := 'Select Ename from Scott.emp Where empno = 7369';
Open C_Ref for V_Str;
Fetch C_ref Into V_Name;
close C_Ref;
dbms_output.put_line(V_Name);
End;

Using dynamic sql in triggers with :OLD values

i need to record all deleted rows from an entire schema in a single table. for that matter i created a function that receives a table name and generate an insert command according to it's primary key columns. i call this function in the table triggers. in order to insert the old values before the delete i use :OLD with "execute immediate" as followed :
create or replace trigger trg_some_tbl_bd
before delete on some_tbl
for each row is
declare
v_sql varchar2(4000);
begin
v_sql := generate_insert_command('some_table');
execute immediate v_sql;
end;
the return value from "generate_insert_command" function is the string:
insert into deleted_table (table_name , date , pk1 , pk2) values
('some_table' , sysdate , :OLD.pk1 , :OLD.pk2)
the execute immediate command notice the :OLD and looks for bind variables.
i need to know i can i bypass that. i tried looking for escape characters but couldent find any...
i would appriciate any help , it's kynda urgent
Thanks !

I don't believe this is going to work. Even if you could get around the fact that :old looks like a bind variable, the :old values are not visible to the dynamic SQL statement, they're like local variables in that respect.
If you wanted to pass old values in, those values would have to be passed in as bind variables, i.e.
EXECUTE IMMEDIATE v_sql USING :old.pk1, :old.pk2which defeats the purpose of using dynamic SQL.
Since you have to create a trigger for each table, I don't see why you would bother with dynamic SQL inside the trigger-- your table structure is fixed when the trigger is created. You could write dynamic SQL that generated the triggers in the first place, but the code inside the trigger should be dynamic.
As an aside, you realize that logging every audit record into a single table creates rather massive contention issues, right? And have you considered how painful it is to query this sort of table? Have you considered other options for maintaining history like Workspace Manager? Or at least separate history tables for each table?

Hello,
>
I'm trying to create a function utilizing Dynamic SQL. But why?
Whenever you turn towards dynamic SQL, ask yourself why?
I bet for a couple of years you aren't able rto come up with an answer. Meaning you shouldn't.
Even if you do come up with an answer, think again. The answer may very well be wrong.
Wouldn't it be nice if your function was as simple as:
CREATE OR REPLACE FUNCTION prod_sales_data
   ( p_ahl1      IN VARCHAR2
   , p_phl1      IN VARCHAR2
   , p_fisyr     IN NUMBER,
     p_prod_str IN VARCHAR2)
RETURN NUMBER
IS
   v_return NUMBER;
BEGIN
    select sum(a.qsh*a.unitcnt)
      into v_return
      from sh_units a
         , sh_product_desc b
         , sh_ad_glass c
     where a.unittype = b.unittype
       and a.sh_id = c.sh_id(+)
       and a.ahl1 = p_ahl1
       and a.phl1 = p_phl1
       and a.fisyr = p_fisyr
       and upper(b.descrip) = upper(p_prod_str)
       and a.invdt between b.eff_beg and b.eff_end
       and a.parts_flag != 'Y'
       and a.unittype != 'OTHE'
       and icim.sh_rept_chk_ortp(a.ortp) = 1
       and a.rept_release_dt is not null;
RETURN v_return;
EXCEPTION
   WHEN NO_DATA_FOUND THEN
      RETURN NULL;
END prod_sales_data ;
/Now using proper bind variables, plain static pre-compiled SQL. And even works properly WITH NO DATA FOUND.
I know it's dangerous to use words as always and never, but i dare say
Always (Whenever you can) use static SQL. Never (Unless you must) use dynamic SQL (When you can use static).

Should I use dynamic SQL for simple updates?

Please tell me, out of the two options given below, which option should i use to update columns in a table and why?
what will be the performance difference between the two approaches?
Please note: The options given below is just for an example
procedure proc1(var1 varchar2)
is
begin
update tab1 set col1 = var1;
commit;
end;
procedure proc1(var1 varchar2)
is
sqlstr varchar2(1000);
begin
sqlstr := 'update tab1 set col1 = :v1';
execute immediate sqlstr using var1;
commit;
end;
Thanks
Arun

Arun G Nath wrote:.

Performance is not the issue (as long as you are using bind variables).
But with dynamic SQL, you loose compile time checking; you do not know until runtime if the SQL is valid.
You also loose the dependency between proc1 and tab1, which can be found only if you search user_source.
(And in either case, you probably want to remove the commit)

Help with using dynamic sql logic in a view please?

Greetings,
I want to create a dynamic union using all the databases on server. The following works:
declare @sqlvarchar(max)
select
@sql=IsNull(@sql+'union
all ','')+'select
* from '+name+'.[dbo].[A]''
inner join '+name+'.[dbo].[B]'' on
a.f1=b.f1'
from
sys.databases
where
name
in(select
name
from
sys.databases)
exec
(@sql)
The problem is I need something tangible, like a view, to query using SSAS later. I've tried to use SELECT into to load a new table with a resulting dataset. It gives me a syntax error - the dynamic part can't be combined with static. I can't use OPENQUERY
because it all happens on the same server. Assistance would be appreciated. Thanks

Well, you could regenerate the view each time a database is created or dropped.
Or you can define your cube using an empty view and load the cube using SSIS, eg with
Dimension Processing Destination.
Or you can use something like a CLR TVF inside your view.

How to use dynamic SQL in this case for best performance

I have the table with following columns
ID NUMBER,
DATA LONG,
TAG VARCHAR2(255)
Records in this table will be like following
1 this is an abstract ABSTRACT
1 this is author AUTHOR
1 100 PRICE
2 this is an abstract ABSTRACT
2 this is author AUTHOR
3 contract is this CONTRACT
Basically all the records with the same number constitute 1 record for another table. Tag in the above table indicates that what column it is and DATAwill have the actual data for that column. I need to populate the second table based an the above table but will not get the same number of TAGS all the time. I need to insert the values only for the columns provided in the TAG field. How will I accomplish this by dynamic sql. Do I create a loop and create two strings one with columns and one with values and then combine them and use execute immediate to insert into table? Is there an easier way to do this??
Please respond quickly.
Thanks

Program to interfaces. That way, you can switch out implementations and test for yourself which performance is best in an actual production context. But first, write your program so that it works. Worry about refactoring for performance once your program is written and it works.

Using Dynamic SQL in OWB maps

Hi,
Is there any way that we can write dynamic SQL in OWB.As per my requirement i want to change the where clauses dynamically on need basis.
Thx

David,
I want to change the where clause dynamically.Our objective is to make the map in a generic way so that if there is a change in where clause (i.e. adding more conditions in where clause) i dont have to change the map.I can change the values(if used, say emp_no=20) however i'm facing problem changing the whole condition i.e. even the column name.
Thx
