Report for a dynamic SQL Statement

Hi,
I have a dynamic generated SQL query and I want to report the result in a report region like a regular (standard) report.
Is there a PL/SQL package function where I can put the parameters in (like SQL query etc) and outputs me the the HTML Code which I can put with htp.p?
regards
voidy
PS: hope you understand what I mean

Hi Denes (and all the others ;),
well, I was too busy on my Apex projects lately ;). Actually quite an interesting application. Currently I build a high availability solution for 4.500 users, maybe 2.000 using it at the same time.
And I have just recently become a father of a beautiful daughter:

These things have kept me quite busy lately ...

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.

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

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.

And you will have to regularly restart the server, or possibly slightly less invasive, flush the shared pool.

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.

But, please feel free to go ahead with this successful implementation.
I just hope anyone else who reads this doesn't make the same mistake.

awrsqrpt.sql is showing multiple executions plans for a single SQL statement. How is it possible that one SQL statement will have multiple Executions Plans within the same AWR report.If you're using bind variables and you've histograms on your columns which can be created by default in 10g due to the "SIZE AUTO" default "method_opt" parameter of DBMS_STATS.GATHER__STATS it is quite normal that you get different execution plans for the same SQL statement. Depending on the values passed when the statement is hard parsed (this feature is called "bind variable peeking" and enabled by default since 9i) an execution plan is determined and re-used for all further executions of the same "shared" SQL statement.
If now your statement ages out of the shared pool or is invalidated due to some DDL or statistics gathering activity it will be re-parsed and again the values passed in that particular moment will determine the execution plan. If you have skewed data distribution and a histogram in place that reflects that skewness you might get different execution plans depending on the actual values used.
Since this "flip-flop" behaviour can sometimes be counter-productive if you're unlucky and the values used to hard parse the statement leading to a plan that is unsuitable for the majority of values used afterwards, 11g introduced the "adaptive" cursor sharing that attempts to detect such a situation and can automatically re-evaluate the execution plan of the statement.

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.

Avoid Hard Parsing for executing dynamic SQL using DUAL table Oracle

I want to know if dynamic sql statements involving DUAL table can be modified to remove HARD PARSING.
We have several SQL statements are stored in configuration table, here is sample example
-- query 1 before replacing index values as stored in config table ---
select count(*) from dual where 'REPLACE_VALUE_OF_INDEX_3' IN ('K')
AND (('REPLACE_VALUE_OF_INDEX_13' IN ('1053','1095','1199') ) OR ('REPLACE_VALUE_OF_INDEX_13' IN ('1200') ))
AND 'REPLACE_VALUE_OF_INDEX_2' IN ('6')
AND 'REPLACE_VALUE_OF_INDEX_15' IN ('870001305')
-- query 1 after replacing index values--
select count(*) from dual where 'REPLACE_VALUE_OF_INDEX_10' IN ('K')
AND (('1030' IN ('1053','1095','1199') ) OR ('1030' IN ('1200') ))
AND '2' IN ('6')
AND 'X' IN ('870001305')
-- query 2 before replacing index values as stored in config table --
select count(*) from dual where 'REPLACE_VALUE_OF_INDEX_5' IN ('361A','362A')
AND 'REPLACE_VALUE_OF_INDEX_22' BETWEEN '200707' AND '200806'
-- query 2 after replacing index values--
select count(*) from dual where '3MAA' IN ('361A','362A') AND '201304' BETWEEN '200707' AND '200806'

If I got it right you have some (maybe lots of) conditions stored in a table (be patient - it's my interpretation)
create table eb_conditions as
select 1 rid,q'{:5 IN ('361A','362A') AND :3 BETWEEN '200707' AND '200806'}' cndtn from dual union all
select 2,q'{:2 IN ('361A','362A') AND :3 BETWEEN '200707' AND '200806'}' from dual union all
select 3,q'{:1 IN ('K') AND ((:2 IN ('1053','1095','1199') ) OR (:4 IN ('1200') )) AND :3 IN ('6') AND :5 IN ('870001305')}' from dual
RID
CNDTN
1
:5 IN ('361A','362A') AND :3 BETWEEN '200707' AND '200806'
2
:2 IN ('361A','362A') AND :3 BETWEEN '200707' AND '200806'
3
:1 IN ('K') AND ((:2 IN ('1053','1095','1199') ) OR (:4 IN ('1200') )) AND :3 IN ('6') AND :5 IN ('870001305')
and you have to check the conditions using values stored in an array
I used a table instead: the vl at rid = 1 representing the value of bind variable :1 in eb_conditions table and so on ...
create table eb_array as
select 1 rid,'K' vl from dual union all
select 2,'1199' from dual union all
select 3,'200803' from dual union all
select 4,'1000' from dual union all
select 5,'870001305' from dual
RID
VL
1
K
2
1199
3
200803
4
1000

870001305
You want to check the conditions using select count(*) from dual where <condition with binds substituted fron the array>
Judging from the title Hard Parsing represents the major problem and you cannot avoid it since every condition to be verified is different from every other condition.
I think your best bet is not to evaluate conditions row by row - context shift cannot be avoided and there might be more than one for each iteration.
So try to do it in a single step:
declare
w_cndtn varchar2(4000);
w_clob clob;
w_cursor sys_refcursor;
one number;
two number;
begin
dbms_lob.createtemporary(w_clob,false);
for rw in (select rid,
                    max(cndtn) cndtn,
                    listagg(val,',') within group (order by rn)||',' usng
               from (select c.rid,c.cndtn,c.rn,c.bind,

How to get the time for executing an SQL statement?

hi all...
How can I get the total execution time for a given SQL statement to a ViewObject which is created dynamically for this SQL so that the end user knows it before hand and try to stop it or go further..?
Please post any ideas if you have got..!!!
thanx in advance..

This is not really a question for the JDeveloper forum, but rather for the DB forum.
Since Oracle9i there is a way to estimate how long a query will take, before executing it.
Check it out in the Oracle DB documentation or ask on the DB forum.
There is no built-in functionality for this in JDeveloper, but you should be able to call out to the DB from your Java code to get the estimate.

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

Log for all the sql statement executed

Hi,
I would like to know how to see the log for all the sql statement executed starting from connection to all the database related actions.
Is it something that i need to set it up in the driver?
I'm using Tomcat and JDBC driver.
Please reply.
Thanks,
Anjana

Make your own.
Calendar cal = new GregorianCalendar();
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH) + 1;
int day = cal.get(Calendar.DAY_OF_MONTH);
//use calendar object to get other infos such as time of query
//append your query string
File f =new File ("c:\\jakarta-tomcat-3.2.4\\webapps\\ASD\\LOGS\\log" + df.format(day) + df.format(month) + year + ".txt");
               if (! f.exists())
                    f.createNewFile();
               FileWriter fw = new FileWriter (f, true);
               // append new log to end of file
               fw.write(buf.toString());
               fw.write("\n");
               fw.flush();
               fw.close();
          catch (IOException ioe)
               System.out.println(ioe.toString());

Dynamic SQL statements

Hi
Here is an interesting question for all. My application has to support 5 markets. For that I created a report based on querying a view. That report is based on some search criteria which comes through a form. Right now the report is perfectly working as I have queried it as
select * from portland.rsu_inventory where ne = :ne_no
But we have some more markets apart from PORTLAND. For that we want to use the same application. So we have to be able to pass the market name dynamically. I am able to capture the market name in the search croteria form. But how can I send the market name to the Report SQL statement like
select * from | |MarketName| |.rsu_inventory where ne = :ne_no
Here the "MarketName" should be the market name that I would dynamically pass.
How can I acieve this. Thanks for any kind of suggession.
venu

According to the metalink, the new version of OracleAs Portal is no longer support the query statement passing to this wwv_render_report.show procedure but however you can pass the cursor handle to this procedure instead. Here is the sample code to call this procedure:
declare
v_qry_stmt varchar2(32767) ;
v_cur_hdl int;
begin
v_cur_hdl := dbms_sql.open_cursor; -- open cursor
v_qry_stmt := '<your query>';
--Example query:
--v_qry_stmt := 'select empno,ename from scott.emp';
dbms_sql.parse(v_cur_hdl, v_qry_stmt, dbms_sql.native);
PORTAL30.wwv_render_report.show(p_table_border=>'1',
p_heading_bgcolor=>'#FFFFF0',
p_heading_font_face=>'Arial',
p_heading_font_size=>'13',
p_table_bgcolor=>'#FFFFFF',
p_font_face=>'Arial',
p_font_size=>'10',
p_query=>to_char(v_cur_hdl),
p_col_headings=>PORTAL30.wwv_standard_util.string_to_table2('Employee Number:Employee Name')
end;
Thanks

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;

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.

Dynamic SQL Statement with table name

Dear all
i like to have a SQL statement with a dynamic tablename. Is this possible? If yes, how?
should be something like "select * from <mytablename>"
Thank you
Herbert

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

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 ...
