Erratic Report Region Behavior with Dynamic SQL Queries

I'm running HTMLDB v 1.5.1.00.12 and I've noticed some odd behavior with report regions using dynamic SQL queries. Every so often, our testers will run a page containing a dynamic sql report region and get the following error, (despite the fact the query was working only moments ago and no other developer has touched it):
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
or sometimes
failed to parse SQL query:ORA-01403: no data found
The only solution I've found so far is to:
1) Make a copy of the failed report region.
2) Disable or delete the original failed report region.
The new copy of the report region runs without issue.
My search of the forums turned up the following two threads, but neither provided me with a clear explanation of the cause, and how to avoid it:
ORA-06502:PL/SQL: numeric or value error: character string buffer too small
Re: Import Export Error (ORA-06502)
The columns being returned are below the 4000 character limit, and the rows being returned are far less than 32k in size.
Could this have anything to do with the way HTMLDB is internally storing the PL/SQL used to generate the dynamic SQL Query? Is there any known issue related to this with that version of HTMLDB?
This problem occurs without any discernable pattern or consistency, making it hard to determine where I should focus my efforts in tracking down the cause.

Hi all,
My report seems to be behaving correctly once i set it to "Use Generic Column Names (parse query at runtime only)" :)
Cheers,
Joel

Dynamic SQL queries in HTMLDB application

How can i build a HTMLDB page only for dynamic sql queries like the features in the HTMLDB SQL-workshop.
I need a SQL interface for some power user running some ad-hoc queries.
Can i call this page directly from any other HTMLDB application?

Hello Martin,
I am a beginer in APEX but I have the same problem with you. What are your solution for dynamic sql query ? For report a solution is Pl Sql procedure which return a sql query. But for a form ?

Backup DB with dynamic sql - want to substitute in dbname and disk file path

Re: Backup DB with dynamic sql - want to substitute in dbname and disk file path
Hope I can explain this. Below is a small snippet of code. I want to set @SQLTemplate_TSQL once at the top of the script and then execute the SET @SQLCommand and sp_executesql in a loop that reads a list of databases. It all works, except for the
BACKUP DATABASE. Right now it evaluates when the SET @SQLTemplate_TSQL is evaluated. I want it to evaluate when it is executed. I want the DB_NAME() of the USE @dbname.
-- change @dbname and @dbbackuppath
DECLARE @SQLCommand NVARCHAR(MAX)
DECLARE @SQLTemplate_TSQL NVARCHAR(MAX)
DECLARE @dbname varchar(128) = 'Bank04'

set @SQLTemplate_TSQL =
DECLARE @dbbackuppath varchar(128) = ''''d:\backups''''
IF RIGHT(@dbbackuppath, 1) <> ''''\''''
SET @dbbackuppath = @dbbackuppath + ''''\''''
SET @dbbackuppath = @dbbackuppath + DB_Name() + ''''.bak''''
PRINT @dbbackuppath
BACKUP DATABASE ' + DB_NAME() + ' to DISK=''' + QUOTENAME(@dbbackuppath, CHAR(39)) + '''

EXECUTE sp_executesql @SQLCommand

Here is a stripped down version of my code. Someone writes a script. I then take the script and seperate it by GO statement block. Each GO block gets its own row into the
#SQLTemplate_TSQL. I then replace single quote with 4 quotes and run it. Then I run against my list of databases. I am unable to get the BACKUP DATA base to work with this model.

Writing to a temp table in a stored procedure with dynamic sql

Hi
I am writing into a temp table with dynamic sql:
select coloum_name into #temp_table from
+
@DestinationDBName+'.information_schema.tables
and then I am trying to use #temp_table in the procedure:
select coloum_name into #anotherTable from #temp_table
but I am getting an error that #temp_table is not recognized.
Can a temp table not be used in dynamic sql ?
How can I overcome this problem ?

Temp Table Can used easily in Dynamic Query in SQL Server and here is small Exmaple you can check it and do like it
CREATE PROC test
AS
BEGIN
CREATE TABLE #T1
(ID int , NAME Nvarchar(50))
CREATE TABLE #T2
(ID int , NAME Nvarchar(50))
DECLARE @SQL NVARCHAR(MAX)='Insert into #T1
SELECT database_id , Name FROM Sys.Databases
Insert into #T2 Select ID , Name from #T1 '
EXEC SP_ExecuteSQL @SQL
SELECT * FROM #T2
DROP TABLE #T1
DROP TABLE #T2
END
Exec Test

DB2 problems with Dynamic SQL

Does anyone out there use dynamic SQL with DB2? If so, are the sql statements causing a PreparedStatement to be executed on DB2. I posted this question similarly before, but never resolved it, and it is killing me. I have to resolve this ASAP!
Here is the problem: My DB2 Admin says that EVERY TIME I access the database, my Java app is causing the database to create a PreparedStatement. However, I'm using Statement objects exclusively, with dynamic SQL. He says that DB2 needs an "access path" for the client, and that it converts the Statement to a PreparedStatement, as this is the only way to get this "access path". He says the only solution is either stored procedures or SQLJ, which will do the binding in advance, and increase performance tremendously. However, I am STRONGLY opposed to using SQLJ, and if we do stored procedures, we'd have to write one for every possible SQL statment! I KNOW there is a better solution.
Is anyone out there having these problems with JDBC and DB2? Surely someone out there uses DB2 and JDBC and either has these problems or can confirm that something is incorrectly configured on the database side.
Any help would be great. Thanks, Will

Now I'm wondering if maybe the PreparedStatements are ONLY being called on the database when I call getConnection(), and not when I call executeQuery() or executeUpdate() from the Statement object. I just can't see why the database would have to make an access path for every SQL statement executed, but I could see it creating an access path for every connection requested. Any thoughts on that theory?

Help with dynamic SQL

Assuming the requirement is to find the partition in the supplied table with the supplied high value and the issue is that dba/all_tab_partitions.high_value is a long, one alternative along the same lines as you've done already is as follows. (I've just used a cursor rather than a function for simplicity of demo).

Controling Column Order for Report with Dynamic SQL

Hi,
I have a report region using Function block returning the SQL.
The output of the function will look like the following
SELECT NAME, CLASS1, CLASS2,CLASS3,CLASS4, AVERAGE_SCORE FROM XXXX;
The number of CLASSn column will be determine by the function based on the data. If the person doesn't have any score on CLASS4, the the SQL would not have CLASS4 column.
My problem with this is I can't control the order of column appearance.
For e.g : If my previous SQL is without CLASS4, when I query a person with CLASS4. The CLASS4 column will appear after the AVERAGE_SCORE.
NAME---CLASS1---CLASS2---CLASS3---AVERAGE_SCORE---CLASS4
I want it to maintain AVERAGE_SCORE as the last column.
Can you guys give a suggestion how to handle this?
Additional info :
- I am disabling the report header, setting it to None as the first row of the sql returned records is the header.
Cheers,
Joel

2 Report -Regions combine in 1 Report-Region but 2 different SQL-Querys

Hallo,
I have a question.
I have a page and within this page 2 different report-regions. Each of this regions has its own sql-query.
Now I would like to concentrate them in 1 report with one title. But there are still 2 differnet sql-query
that I can't combine. My issue is that I only want to show the result in one report.
Does this work or is there a workaround I could do?
Thanks, Jade

Hi,
As the report region's title is just whatever text you've entered, you can just put the title on the second report onto the first report and set the second report to use "No Template". You would probably need to remove the pagination settings for both reports - select No Pagination and set the row count to a high number.
The final bit would probably require a new report template - you can create a copy of the existing report template that you're using - and remove the Column Heading Template setting. This is only necessary if you need to remove the column headings from the second report. There would be a gap between the two reports - not sure if you need to remove this as well? If so, you would have to adjust both templates to remove the this from the bottom of the first report and the top of the second report.
I think that how you go about this will depend on exactly what you need to see between the two reports - if they need to look as though they are just a single report then you may have to complete all of the above steps.

Connecting a report region and a PL/SQL region

Hi,
I have created a report region whith pagination that only show 1 row at a time. I can then navigate backwards and forwards through this recordset. The first reportcolum in this recordset contains a number.
I have also, on the same page, created a PL/SQL procedure region. What I want is to use the number from the SQL region as an input to the PL/SQL region. So when I navigate through the report (Using the pagination arrows), the PL/SQL region is in sync with the record I'm currently seeing in the report.
Is this possible or do I have to try something different?
Regards
Trond

Hi Trond,
If you only want to show one record in your first region, it might be best to work with page items, retrieve one record at a time and use that data as the source for your page items. It's easier to implement and easier to reference those values in your second region. Reports are great if you have more then one record.
Having said that, there are ways to implement it the way you outlined it in your posting. Granted it's not very elegant but it serves its purpose. You could write your own PL/SQL package, use this to set a global to the current row's primary key value and reference that global in your second region.
Create your package as follows:
create or replace package md_sample as
g_pk_value number;
function set_value(p_value number) return number;
end;
create or replace package body md_sample as
function set_value(p_value in number) return number is
begin
g_pk_value := p_value;
return 1;
end;
end;
Now you need to make sure that your report calls this package appropriately. Calling this as part of your SQL statement won't work properly as it would also be called for records not currently shown on your page. A better way would be to use it for a PL/SQL expression within your report template definition. Pick a custom report template for your report and edit that template. Scroll down to the condition for the first column template and pick Use Based on PL/SQL Expression. Then type in the following expression (this is based on a select deptno, dname, loc from dept report):
md_sample.set_value(#DEPTNO#)=1
After that you'll be able to reference the global md_sample.g_pk_value. You could e.g. use this as the source for page items shown in your second region.
Hope this helps,
Marc

Using bind variables (in & out) with dynamic sql

I got a table that holds pl/sql code snippets to do validations on a set of data. what the code basically does is receiving a ID and returning a number of errors found.
To execute the code I use dynamic sql with two bind variables.
When the codes consists of a simpel query, it works like a charm, for example with this code:
BEGIN
   SELECT COUNT (1)
   INTO :1
   FROM articles atl
   WHERE ATL.CSE_ID = :2 AND cgp_id IS NULL;
END;however when I get to some more complex validations that need to do calculations or execute multiple queries, I'm running into trouble.
I've boiled the problem down into this:
DECLARE
   counter   NUMBER;
   my_id     NUMBER := 61;
BEGIN
   EXECUTE IMMEDIATE ('
      declare
         some_var number;
      begin
      select 1 into some_var from dual
      where :2 = 61;
      :1 := :2;
      end;
      USING OUT counter, IN my_id;
   DBMS_OUTPUT.put_line (counter || '-' || my_id);
END;this code doesn't really make any sense, but it's just to show you what the problem is. When I execute this code, I get the error
ORA-6537 OUT bind variable bound to an IN position
The error doesn't seem to make sense, :2 is the only IN bind variable, and it's only used in a where clause.
As soon as I remove that where clause , the code will work again (giving me 61-61, in case you liked to know).
Any idea whats going wrong? Am I just using the bind variables in a way you're not supposed to use them?
I'm using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit

Correction. With execute immediate binding is by position, but binds do not need to be repeated. So my statement above is incorrect..
You need to bind it once only - but bind by position. And the bind must match how the bind variable is used.
If the bind variable never assigns a value in the code, bind as IN.
If the bind variable assigns a value in the code, bind as OUT.
If the bind variable assigns a value and is used a variable in any other statement in the code, bind as IN OUT.
E.g.
SQL> create or replace procedure FooProc is
2          cnt     number;
3          id      number := 61;
4 begin

16 end;

Flash chart with dynamic sql query does not display

Hi,
In my schema SIVOA I have a lot of tables declared like this :
CREATE TABLE "SIVOA"."EVV_xxxx"
   (     "CLEF_VAR" NUMBER(4,0),
     "DATE1" DATE,
     "VALEUR" NUMBER(16,8) Only the last part of the name changes "xxxx". For example E009, E019, etc....
I am making a chart page with report and want the user to select a name of a table and I will display using dynamic sql query, the table report and chart.
P184_ENAME is a select list returning the last part of the name of the table, fro example 'E009', 'E019', etc.
P8_CLEF_VAR is an item containing a value. This value is a key retrieved like this :SELECT CLEF_VAR
FROM SIVOA.SITE_ECHELLE
WHERE SITE = :P184_ENAMEI built a classic report using a sql dynamic function :DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = :p8_clef_var' ;
RETURN (x);
END;:p8_clef_var is an itme containing the value '4544'.
This works perfectly fine !
When I use this sql fucytion into a flash chart it does not work. I get this message "No data found".
I do not understand why a the report get a result and not the chart !
But if i hard-code the number of the CLEF_VAR instead of fetching it from :p8_clef_var I get a nice chart ! Go figure !DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = 4544 ' ;
RETURN (x);
I cannot stay with the key (CLEF_VAR) hard-coded unformtunately !
My question is how to get the chart displaying properly ??
Thank you for your kind answers.
Christian

Alex,
Using your request, with the classic report I get results (data), but I get the same message with the Flash chart : "No data found" ! I don't know how to investigate this. i tried many things but nothing works.
Christian
PS I tried this :
DECLARE
   X   VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, ROUND(VALEUR,2) FROM SIVOA.EVV_'
      || UPPER (:p184_ename) ||
      ' WHERE CLEF_VAR = '
      || :p8_clef_var ||
      ' AND DATE1 BETWEEN TO_DATE ('''
||:P8_DATE_DEBUT||''', ''DD/MM/YYYY HH24:MI'') AND TO_DATE ('''
||:P8_DATE_FIN||''', ''DD/MM/YYYY HH24:MI'')'
RETURN (X);
END; But it does not work either. I could find that the SLQ syntax generated is good becaus I put it into an item which display the return done by the pls/sql.
What is sttange also with the classic report is that if I do click on next or previous to see another rows, I get the message "No data found". If I try to export the report I get an excel file with "No data fouid".
Does anybody already tried my "need" here ? i find strange thant I should not be the firs one trying to get a report an tables which name would be "dynamic".
Tahnk you.

SSRS - Stored procedure with Dynamic SQL Query

Am calling stored procedure in SSRS report. I have used Dynamic SQL query in stored procedure as I don't know the column name and column count. And I have used like below at end of the stored procedure "select * from ##temptable".
As I have used dynamic column, am not able to create report with this stored procedure. Can someone help me out to resolve this issue.
It will be highly appreciated if I get help.
Thanks

I have tried everything. But nothing has worked out.
If I get solution for below issue, it would be highly appreciated.
"An error occurred during local report processing.

ERROR creating table with dynamic SQL :-(

Hi friends,
I have a problem when I try to create a table using dynamic SQL.
(Env.: Forms 6i, WinXP, Oracle 9i)
I only want to create a table, insert data and drop the table.
I have a user with the correct privileges (At least ....I think so), because I can to make the three actions in SQL*PLUS (CREATE TABLE, INSERT .. and DROP TABLE).
I want to do the same in Forms using dynamic SQL...
I've made a package with 3 procedures:
1st to create the table, 2nd to insert data , 3rd to drop the table.
Only the 1st fails with the error ORA-01031 (insufficient privileges).
Here it is:
PROCEDURE PRO_DM_CreaTabla(pe_nombre_tabla VARCHAR2) IS
id_cursor INTEGER;
ls_sentencia VARCHAR2(500);
v_dummy integer;
BEGIN
id_cursor := DBMS_SQL.OPEN_CURSOR;
ls_sentencia := 'CREATE TABLE '||pe_nombre_tabla||' ( campo1 VARCHAR2(100), campo2 VARCHAR2(100), campo3 VARCHAR2(100),campo4 VARCHAR2(100))';
DBMS_SQL.PARSE(id_cursor, ls_sentencia, dbms_sql.NATIVE);
v_dummy := dbms_sql.execute(id_cursor);
DBMS_SQL.CLOSE_CURSOR(id_cursor);
END;
The DROP_table procedure is exactly the same as this (with the difference of the 'CREATE' sentence, where I have a DROP sentence)... then.. why the DROP procedure works?... and.. why this CREATE procedure doesn't work?
Any ideas?
Thanks a lot.

commit;First, try your statement in SQL Plus:
INSERT INTO TMP_TABLE(field1,field3,field3,field4) VALUES (1,2,3,4);
Then if that works, try doing this right after the Forms_DDL(V_INSERT);
If not form_success then

Raise form_trigger_failure;

Crystal Reports not working with PL/SQL

When I try and connect a Oracle stored procedure in ODBC using Oracle 8.1.7 client and Crystal 8 Reports I get the following error:
ODBC error: [MERANT][ODBC Oracle 8 driver][Oracle 8]ORA-06550: line 1, column 13: PLS-00302: component 'TEST_PROCEDURE' must be declared
ORA-06550: line 1, column 8: PL/SQL: Statement ignored
This code worked just fine in Crystal Reports 7. Does anyone know how to get this to work? Any successful code snippets to share? I called Crystal Decisions Support with no luck at all.
Thanks!

Yes, the dialog is different than in Crystal 7 but the box is already checked.

Depending on how Crystal 8 was installed this setting may be different than what you have been using in Crystal 7.

Query with Dynamic SQL

Hello,
I would like to create a Dynamic SQL in which change is the name of the table according to the outcome of the first SQL. This is possible?
'WITH TABLE_X AS(SELECT LEVEL LVL FROM DUAL CONNECT BY LEVEL <= 12)' ||
'SELECT A.COL1, A.COL2, B.COL1, B.COL7'                              ||
' FROM TABLE_A' || TABLE_X.LVL || ' A'                              ||
'     , TABLE_B' || TABLE_X.LVL || ' B'                              ||
' WHERE A.COL1 = B.COL1 AND ...    'tables in database
TABLE_A1
TABLE_A2
TABLE_A12
TABLE_B1
TABLE_B2
TABLE_B12let me know how I can do this
Regards

Hi,
Sorry, I don't see what you're trying to do.
"Dynamic SQL" is really a mis-nomer. The number of tables and columns in a query, and their names, must be spelled out when the statement is compiled. There is nothing dynamic about it.
In dynamic SQL, a PL/SQL procedure or another query writes all or part of query just milliseconds before it is compiled, typically using data taken from tables or supplied by a user right then.
For example, consider this static query:
SELECT     a.col1, a.col2, b.col1, b.col7
FROM     table_1     a
,     table_2 b
WHERE     a.col1 = b.col1;Now, say the 1 in "table_1" and the 2 in "table_2" are variables, x and y, that you will want to look up from another table every time you run this query. You can make it dynamic like this:
sql_txt := 'SELECT a.col1, a.col2, b.col1, b.col7 '
     || 'FROM    table_' || TO_CHAR (x) || ' a '
     || ',       table_' || TO_CHAR (y) || ' b '
     || 'WHERE   a.col_1 = b.col1';Now let's make it really interesting. Say that instead of 2 tables, and 1 join condition, you''ll have n tables and n-1 join conditions, where n has to be computed at (actually a split second before) run-time. That is, if n=4, you might need to construct a static query with 4 tables and 3 join conditions, like this:
SELECT     a.col1, a.col2, b.col1, b.col7
FROM     table_1     a
,     table_2 b
,     table_12 c
,     table_2 d
WHERE     a.col1 = b.col1
AND     a.col1 = c.col1
AND     a.col1 = d.col1;You can do that using dynamic SQL, too.
Post an example of the static query you need to build, and describe what parts of it are dynamic, and how you get the values for those parts, and someone will help you write the dynamic SQL.
