Help please.
Could I set the bind variable via SQL Plus? I have tried doing it using EXEC :variable :14.
The bind variable is a SELECT List on a APEX form.

Concatenate problem for Dynamic SQL statements

Hi Experts ,
I am building Dynamic SQL statements depending on the values which the user enters into the select option parameters .This dynamic query is passed to cl_sql_connection object for querying from another databasse
So i wrote dynamic values for one select option spointof for the database field ppointofdelivery.
loop at spointof.
CONCATENATE ' pointofdelivery between ''' spointof-low''''
' AND ''' spointof-high''''
INTO where_clause .
endloop.
The whereclause has value pointofdelivery between '123' and '124'.(if the user has entered 123 and 124 as values)
This works fine . But my problem is I have to pass the fieldnames and operator dynamically into where_clause depending on User input.
when i am writing code like the below
field_name = ' pointofdelivery '.
operator = '='.
CONCATENATE field_name operator '''spointof-low''' INTO where_clause .
the where_clause contains value
pointofdelivery = ' spointof-low '
and not pointofdelivery = ' 123 ' as expected .
Do you know why this is haapening as it is not taking the value.
Thanks
Arshad

Hi,
there are lot of function modules..available...to build a where clause based on the select-options..
check the FM FREE_SELECTIONS_RANGE_2_WHERE

        to achieve this?
        Thanks,

This very simple: We cannot use dynamic SQL from used-defined functions written in T-SQL. This is because you are not permitted do anything in a UDF that could change the database state (as the UDF may be invoked as part of a query). Since you can
do anything from dynamic SQL, including updates, it is obvious why dynamic SQL is not permitted as per the microsoft..
In SQL 2005 and later, we could implement your function as a CLR function. Recall that all data access from the CLR is dynamic SQL. (here you are safe-guarded, so that if you perform an update operation from your function, you will get caught.) A word of warning
though: data access from scalar UDFs can often give performance problems and its not recommended too..

      Hi Raju,
       Can you help me writing CLR for my above function? I am newbie to SQL CLR programming.

How can I open a cursor for dynamic sql statement

Hi,
I'm facing issues opening a cursor for dynamic sql statement : PLS-00455: cursor 'RESULT1' cannot be used in dynamic SQL OPEN statement.
CREATE OR REPLACE FUNCTION DEMO
(MN_I in VARCHAR)
return AB_OWNER.ABC_Type.NonCurTyp is
RESULT1 AB_OWNER.ABC_Type.NonCurTyp;
sql_stmt VARCHAR2(4000);
BEGIN
sql_stmt := 'SELECT * FROM AB_OWNER.DUN WHERE JZ_I in ('||mn_i||') ORDER BY app.ACC_I';
OPEN RESULT1 FOR sql_stmt;
END IF;
return RESULT1;
END DEMO;
What changes should I make in the code so that it doesn't fail? I can't change the definition of RESULT1 cursor though.

Ok, this is an easy one to diagnose.
You are not using bind variables. This is terrible. Flushing the shared pool is a bad
solution -- you are literally killing the performance on your box by not using them.
If I was to write a book on how to build non scalable applications in Oracle, this
would be the first and last chapter. This is a major cause of performance issues and a
major inhibitor of scalability in Oracle. The way the Oracle shared pool (a very
important shared memory data structure) operates is predicated on developers using bind
variables. If you want to make Oracle run slowly, even grind to a total halt just
refuse to use them.

Build dynamic SQL query in Database Adapter.

Hi All,
I have a requirement to build dynamic sql query at Database Adapter.
My BPEL process is getting search spec as input from siebel. I need to process this searchspec in BPEL and need to build the SQL query dynamically at Database Adapter to fetch the records from DB.
it goes like this....
1. Sieble Search Spec: city1 OR city2 OR city3 OR city4 .....
I need to build query as
select * from S_ADDR_PER where city like 'city1' OR city like 'city2' OR city like 'city3' OR city like 'city4' ......
2. Siebel Search spec: city1 AND country1 AND state1....
I need to build query as
Select * from S_ADDR_PER where city like 'city1' AND country like 'country1' AND state like 'state1' ....
3. Siebel Search spec: state
I need to build query as
select * from S_ADDR_PER where state like '%state%';
Is it feasible in Database Adapter? if its Yes.
Any guidelines to achieve this?
Thank you
Chandra

Help With SUBSTR in dynamic SQL statement

Following is the dynamic SQL statement.
EXECUTE IMMEDIATE 'UPDATE table_name pml
SET pml.'|| con_fields.field ||' = SUBSTR(pml.'||con_fields.field||' ||'' ''||
(SELECT pml1.'||con_fields.field||'
FROM table_name pml1
WHERE pml1.grp_id = '||los_concats.grp_id ||'
AND pml1.row_id = '||los_concats.row_id||'
AND pml1.loser_flg = ''Y''),1, '||con_fields.max_length||')
WHERE pml.grp_id = '||los_concats.grp_id ||'
AND pml.loser_flg IS NULL ';
what it does is that it updates a particular field. This field is concatenated by a field of a similar record.
My problem is with SUBSTR function. Since I am concatenating fields I do not want the field to be updated greater than max_length on that field, the reason why I use SUBSTR. the select query inside SUBSTR works alright with one of the AND condition in a WHERE clause not present. When I add that additional condition it gives me this error.
ORA-00907: missing right parenthesis.
Is there any way to get around this problem. Does SQL has other than SUBSTR function which can limit the character length.
Appreciate it.

The other alternative I thought about was to do this first
EXECUTE IMMEDIATE 'SELECT pml.'||con_fields.field||'
FROM table_name pml
WHERE pml.grp_id = '||los_concats.grp_id||'
AND pml.row_id = '||los_concats.row_id||'
AND pml.loser_flg = ''Y''
' INTO v_concat_field;
write into the variable v_concat_field and then use it into the previous script.
But on this I get SQL Command not properly terminated, I don't get it Why?
Donald I tried with your suggested script. It works fine with one of the conditions eliminated. I don't understand what the error trying to say?
Thanks

How can I execute Dynamic SQL statement in Forms?

Hi All,
I have to execute dynamic SQL statement from Forms
Below statement I have to execute
"EXECUTE IMMEDIATE v_stmt INTO v_return;".
Googled for the same got results saying, Better use Database function or procedures to execute these Dynamic Statements but We want to execute in forms only.
Can any one help me..
Thanks,
Madhu

So in short you are trading code obfuscation for maintainability and the ability to share code between tools? If from somewhere else you need a procedure already implemented in database PL/SQL (and now ported to forms) this would mean you'd need to implement it in every other tool. In times where you might want to integrate your forms with $other_technology and putting stuff on the database is the first step to share functionality you just go the opposite way? And all that because someone is afraid that somebody might steal your source code? I am sorry to be blunt, but this is just plain stupid.
Leaving aside that some things like Analytic Functions, Bulk processing or execute immediate are not even available in forms your software consists of how many LOC? How long does it take to bring a new developer up to speed with your source code? Imagine how long that would take for a developer who doesn't have coleagues who know their way around.
And just so you know: I work for a ISV selling a closed-source product as well. We have 200+ customers all over the planet. We are well aware that wrapped packages can be reverse engineered. The premise is: stored procedures can be reused in every tool we have, if it makes sense to put stuff on the database by all means do it. If someone would want to reverse engineer our software I'd wish him good luck as some parts are implemented in such a hilarious complicated way I have troubles understanding them (and quite frankly I refuse to understand certain parts, but that's another story). I do work for almost 10 years for that ISV.
In any case the possible solutions have already been mentioned: you have exec_sql, create_group_from_query and forms_ddl to execute dynamic SQL in forms whereas forms_ddl is a one way street and most certainly not the thing you need or want. Take a look at the documentation for the other 2 things.

Preparing Dynamic SQL statement for inserting in Pro*C

Hi Friends,
From quite some time i am struggling writing Dynamic SQL statement for dynamic insert and update in Pro*C.
Can somebody go through my code and suggest me the rigth way of doing.
Right now it throws an error saying " Error while updating ORA-00904: invalid column name "
Please help me.
Girish.
int main()
EXEC SQL BEGIN DECLARE SECTION;
char *uid ="scott/tiger";
static char sqlstmt[129];
struct /* DEPT record */
int dept_num;
char dept_name[15];
char location[14];
} dept_rec;
EXEC SQL END DECLARE SECTION;
EXEC SQL WHENEVER SQLERROR DO sql_error();
EXEC SQL CONNECT :uid;
dept_rec.dept_num = 50;
strcpy(dept_rec.dept_name,"ADMIN");
strcpy(dept_rec.location,"IN");
strcpy(sqlstmt,"UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num");
EXEC SQL EXECUTE IMMEDIATE:sqlstmt;
EXEC SQL COMMIT;
exit(0);
void sql_error()
printf("\nError while updating %s",sqlca.sqlerrm.sqlerrmc);
EXEC SQL ROLLBACK;
}

A bit rusty here but this is how I see it.
Think of it this way ..
all Oracle is going to see is:
UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num
Its NOT going to know what dept_rec.dept_name is or dept_rec.dept_num is ..
it doesnt go back and fill in those values.
You need something like
strcpy(sqlstmt,"UPDATE dept set DNAME = \"");
strcat(sqlstmt,dept_rec.dept_name);
strcat(sqlstmt,"\" where DEPTNO = ");
strcat(sqlstmt,dept_rec.dept_num);
printf(sqlsmt); # Just to be sure the update statement look right during testing.

Build dynamic sql query

We would like to build our sql statements based on the parameters passed in. Does anyone know how to do this.
for example say something like
select business_name from business where
if input_user_id <> "" then
user_id = input_user_id;
else
user_manager_id = input_manager_id;
end if;

Hi Howard
Use a reference parameter in your query. Set the initial value of referece to "user_manager_id=input_manager_id". At runtime, the user may change the "WHERE" clause by entering an appropriate value in the parameter form.
* Create a query as: select business_name from business where &P_1
* The initial value of P_1 should be set to: user_manager_id=input_manager_id
* At runtime, the user will be prompted to enter values for P_1. The user may then specify "user_id=input_user_id" for P_1 or leave it alone.

Execute Dynamic SQL statement using procedure builder

i want to execute a dynamic SQL statment using procedure builder not using forms
because my statement depending on a variable table name
i know that i can do that from forms using
FORMS_DDL('SQL_STAT');
but i wanna to use the procedure builder
which function i should use and how?
please explain in example if you don't mind.
thanks

Hi,
You can very well use DBMS_SQL Package supplied by Oracle for doing this.
Search for DBMS_SQL in OTN. You will get all info regarding this.

Comparintg times in a dynamic sql statement

I am working on a coversion procedure from one database to another. I have a move procedure that calls functions and the like .
I am trying to use dynamic sql and my where clause is giving me errors. What am I missing here ? TIA....
DEFINE DATECUTOFF ='11-JAN-05' of type date
DES_DATE is a date column in the 2nd database .... type date
I am building strings to do a create table from the 2nd database ...
Testwhere := q'[where to_char("des_date", 'DD-MM-YY') < '01-JAN-05]'; === works but I want to pass in date variable
Teststring := 'Create table '|| table_name || ' as select * from '|| second_table||'@'Linkname
execute immediate teststring || ''|| testwhere;
Testwhere := q'[where to_char("des_date", 'DD-MM_YY') < to_char(DATECUTOFF, 'DD-MON-YY')]; gives me errors like invalid number, or invalid type depending on where the quotes are or how I define DATECUTOFF
Any ideas of what I am doing wrong in comparing the two dates ?
Thanks.

Sorry if I confused anyone ... we're working a duo effort here and get confused ourselves. Here's a summary of the effort.
We're on 11G Linux.
We're writing scripts, procedures and functions that will help us transition from a remote database (Ingres) to oracle. We plan to do this for many dbs, so we are using variables for the table names, links, etc ....
The Where clase that we are developing is pretty
complex, so our initial attempts to build it is
to make it into two sections as a "literal" , join them and do a execute immediate. A date fields seem to be the issue...
Our main procedure calls a datamove function to do the select from the remote data base....
DATECUTOFF is date;
TESTWHERE is varchar2(600);
TESTSTRING varchar2(600);
TestString := 'Create table '|| table_name_temp|| as select * from '||remote_table_name||'@'Linkname;
TestWhere :=q'[ Where ||des_date < 'DATECUTOFF'];
execute immediate Teststring || '' ||Testwhere;
Can I do this in dynamic plsql ? the des_date is the column from the remote database. DATACUTOFF comes from the main procedure passed in.
I do a DBMS_OUTPUT.Put_Line{teststring);
DBMS_OUPUT.Put_Line(testwhere);
and get the following on my screen
Create Table AC_KEY_TEMP as select * from ACK_KEY2@DBLINK2
where "des_date" = 11-Jan-05
DECLARE
Error at line 1;
ORA-00904 "JAN" invalid identfier
ORA- 06512 at datamove.datamove, line 146
ORA-06512 at line 49, which is the line for
the TestWHERE string.
so in the procedure, if DBMS_OUTPUT is correct, the execute immediate is operating on the where clause and it
thinks the JAN field is incorrect. I have put single quotes around it as well ...

Dynamic SQL statement in a Procedure

Hi,
is it possible to use a variable in place of a column name in a sql statement inside a procedure. Or to create the whole statement as a sql statement and execute it (preferrably with parameters - rather than concatinating the values).
Thanks for any help or direction
Elliot

Turns out you can do the following very nicely (dynamic sql with parameterized values)
Declare
id number(10,0);
sql_stmt varchar2(300);
fieldName varchar2(30);
fieldValue varchar2(100);
id := 30;
fieldName := 'somecolumn';
fieldValue := 'some value';
sql_stmt := 'UPDATE myTable SET ' || fieldName || ' = :1 WHERE id = :2';
EXECUTE IMMEDIATE sql_stmt USING fieldValue, id;

Calling a PL/SQL function in the SQL statement

I have a PL/SQL function which i should call in a SQL statement.
Let's say the function is func1(parameter1,parameter2),
it should be called like this :- SELECT func1() FROM mytable ;
Can any one help me out on this ?
---Thanx in advance

you can call pl/sql functions from pl/sql using
select fn1('param1','param2') from table;
if you dont want to pass paramters, you have to specify default
value while creating function like below
create function fn1(p1 number default null,p2 varchar2 default
null) return...
now you can call using
select fn1 from table;

Using sql function in xml sql statement

Hello,
I have following statement:
select field1, field2,....,field10 from table( cast (get_mhdata(:1,:2) as mhdata))
where mhdata is an oracle type with 10 fields.
It works good, but I don't know how can I use this statement in xml sql statement.
Please, can you tell me if it is really possible.
Thanks in regards.

Hi
You cant pass the parameters if you are executing writing this select function from the communication channel.
You have 3 options:
1) Use a stored procedure and execute from the communication channel
2) Use a stored procedure and execute via message mapping in the IR - here you can pass parameters
3) Same as above but call the query via SQL select - you can also pass parameters.

Yes this is possible. use the below reference code for this.
data: g_tablename type w_tabname,
gv_dref TYPE REF TO data.
FIELD-SYMBOLS: <g_itab> TYPE STANDARD TABLE.
gv_tabname = p_tablename (take table name form selection screen or as per ur requirement)
CREATE DATA gv_dref TYPE TABLE OF (g_tabname).
ASSIGN gv_dref->* TO <g_itab>.
now use the below select query to fetch the data
SELECT * FROM (gv_tabname) INTO TABLE <g_itab>.
Hope this will help
