SQL Query limit

How many characters long can a SQL query be? I'm generating an update query on the fly in a stored procedure using some variables and don't know exact length of these queries.
Thanks in advance!

By "generating an update statement on the fly", do you mean that you are using dynamic SQL? If so, are you using EXECUTE IMMEDIATE? Or DBMS_SQL?
If you are using EXECUTE IMMEDIATE, there is a [limit on the length of the string|http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:6161200355268] that depends on a number of factors, but anything over 32k probably isn't safe. DBMS_SQL can allow you to generate effectively unlimited length SQL statements if you are using the right methods.
Of course, I would want to make sure that dynamic SQL is really needed in the first place. And I would be very concerned if that dynamic SQL were generating queries longer than 32k.

Is there a fix limit how long an SQL query may be?

Hello,
I am currently writing an application (java/jdbc/thin-driver) which executes a simple but very big query which looks like the following:
SELECT CALKEY, PERSNO, MANDT FROM PERSONS WHERE MANDT='1' AND PERSNO='100471' OR MANDT='1' AND PERSNO='100838' OR MANDT='1' AND PERSNO='101010' (to be continued the next 400kb)
For now I am not able to test it with oracle but a not as professional database aborts simply by throwing an SQLException even with that "small" 400kb query, however this query could easily grow to 2-5mb too.
Will the oracle jdbc-thin driver correctly process that large queries (and how fast?) and are there limits for the size of an SQL query?
Thank you in advance, lg Clemens

Hello and thats a lot for the suggestions and tips you gave me.
where does all those 100471, 100838 came from ? would
not it make sense to have those in the database?The problem lies in the fact that I get this data from our sap->db interface with beeing the "100471" the personal numbers of our users. So it would not make that much sence (from the performance point of view) to create a temporary table since the whole time needed to create+fill+drop the table would take longer than this approach.
Thanks for the tips with the different synthax this really should reduce the lenght of the query.
I also implemented a lenght-limit now, if the query string would become larger than a dynamically set limit a second query is generated and results are both added to a list.
Thanks a lot for all this useful tips and suggestion, lg Clemens

Kodo 3.4.1: how to limit # of sql query params when using collection param

Hi,
We have a problem when using Kodo 3.4.1 against SQL Server 2005, when we execute query:
          Query query = pm.newQuery( extent, "IdList.contains( this )" );
          query.declareParameters( "Collection IdList" );
          query.declareImports( "import java.util.Collection;" );
          return (List) query.execute( list );
We got:
com.microsoft.sqlserver.jdbc.SQLServerException: The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Too many parameters were provided in this RPC request. The maximum is 2100.

It seems that there're too many ids in the list, and Kodo didn't limit the # of sql parameters when craft the sql query. Is there a way to ask Kodo to use multiple queries with smaller # of sql parameters instead of using one big sql query?
Thanks

Hi,
Sadly, there is no way to do that in Kodo currently. The closest is the inClauseLimit DBDictionary setting, but that setting just breaks things up into multiple IN statements put together with an OR clause. In your case, it looks like the network transport, not the SQL parser, is complaining about size limits.
You could force the query to run in-memory, but that would probably be prohibitively slow, unless the data set that you're querying against is relatively small.

PL/SQL function body returning SQL query - ORA-06502: PL/SQL: numeric or value error

I'm attempting to dynamically generate a rather large SQL query via the "PL/SQL function body returning SQL query" report region option. The SQL query generated will possibly be over 32K. When I execute my page, I sometimes receive the "ORA-06502: PL/SQL: numeric or value error" which points to a larger than 32K query that was generated. I've seen other posts in the forum related to this dynamic SQL size limitation issue, but they are older (pre-2010) and point to the 32K limit of the DNS (EXECUTE IMMEDIATE) and DBMS_SQL. I found this post (dynamic sql enhancements in 11g) which discusses 11g no longer having the 32K size limitation for generating dynamic SQL. Our environment is on 11gR2 and using ApEx 4.2.1. I do not know which dynamic SQL method -- DNS or DBMS_SQL -- ApEx 4.2.1 is using. Can someone clarify for me which dynamic SQL method ApEx uses to implement the "PL/SQL function body returning SQL query" option?
As a test, I created a page on apex.oracle.com with a report region with the following source:
declare
l_stub varchar2(25) := 'select * from sys.dual ';
l_sql clob := l_stub || 'union all ';
br     number(3) := 33;
begin
while length ( l_sql ) < 34000 loop
    l_sql := l_sql || l_stub || 'union all ';
end loop;
l_sql := l_sql || l_stub;
for i in 1 .. ceil ( length ( l_sql ) / br ) loop
    dbms_output.put_line ( dbms_lob.substr ( l_sql, br, ( ( i - 1 ) * br ) + 1 ) );
end loop;
return l_sql;
end;
The dbms_output section is there to be able to run this code in SQL*Plus and confirm the size of the SQL is indeed larger than 32K. When running this in SQL*Plus, the procedure is successful and produces a proper SQL statement which can be executed. When I put this into the report region on apex.oracle.com, I get the ORA-06502 error.
I can certainly implement a work-around for my issue by creating a 'Before Header' process on the page which populates an ApEx collection with the data I am returning and then the report can simply select from the collection, but according to documentation, the above 32K limitation should be resolved in 11g. Thoughts?
Shane.

What setting do you use in your report properties - especially in Type and in Region Source?
If you have Type="SQL Query", then you should have a SELECT statement in the Region Source. Something like: SELECT .... FROM ... WHERE
According to the ERR-1101 error message, you have probably set Type to "SQL Query (PL/SQL function body returning SQL query)". In this situation APEX expects you to write a body of a PL/SQL function, that will generate the text of a SQL query that APEX should run. So it can be something like:
declare
mycond varchar2(4000);
begin
if :P1_REPORT_SEARCH is not null THEN
mycond:='WHERE LAST_NAME like :P1_REPORT_SEARCH ||''%''';
end if;
return 'select EMPLOYEE_ID, FIRST_NAME, LAST_NAME from EMPLOYEES ' ||mycond;
end;
And for escaping - are you interested in escaping the LIKE wildcards, or the quotes?
For escaping the wildcards in LIKE function so that when the user enters % you will find a record with % and not all functions, look into the SQL Reference:
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/conditions007.htm
(You would than need to change the code of your function accordingly).
If you are interested in escaping the quotes, try to avoid concatenating the values entered by the user into the SQL. If you can, use bind variables instead - as I have in my example above. If you start concatenating the values into the text of SQL, you are open to SQLInjection - user can enter anything, even things that will break your SQL. If you really need to allow users to choose the operator, I would probably give them a separate combo for operators and a textfield for values, than you could check if the operator is one of the allowed ones and create the condition accordingly - and than still use bind variable for inserting the filtering value into the query.

Hi Niels,
As I'm sure you know, the conundrum is that Reports doesn't know how many total pages there will be in the report until it is all done formatting, which is too late for your needs. So, one classical solution to this problem is to run the report twice, storing the total number of pages in the database using a format trigger, and throwing away the output from the first run when you don't know the total number of pages.
Alternatively, you could define a report layout so that the number of pages in the output is completely predictable based upon, say, the number of rows in the main query. E.g., set a limit of one, two, ... rows per page, and then you'll know how many pages there will be simply because you can count the rows in a separate query.
Hope this helps...
regards,
Stewart

How to get cm:search to use the max attribute when creating the SQL query?

When we use the max attribute in the cm:search tag, it does not seem to honor the max attribute when creating the SQL query. However, the result returned from the tag is limited to the number specified by the max attribute. Then the tag seems to work as intended, but the performance will be sub optimal when the SQL query returns unnecessary rows to the application.
We use the cm:search tag to list the latest news (ordered by date), and with the current implementation we have to expect a decrease in performance over time as more news is published. But we can’t live with that. We need to do the constraint in the SQL query, not in the application.
The sortBy attribute of cm:search is translated to “order by” in the SQL query, as expected.
Is it possible to get cm:search to generate the SQL query with an addition of “where rownum <= maxRows”?

Hi Erik,
The behavior of a repository in regards to the search tag's max results parameter is dependent on the underlying repository's implementation. That said, the OOTB repository in WLP does augment the generated SQL to limit the number of rows returned from the database. This is done in the parsing logic. This behavior may differ with other repository implementations.

APEX,PDF's, BI Publisher and SQL Query returning SQL code..

I don't know if I should be posting this in this Forum or the BI Publisher forum, so I am posting in BOTH forums..
I love APEX, let me say that first.. And appreciate the support offered here by the group, but am running int a confusing issue when BI Publisher tries to build a report from the above type APEX report..
Here is my dilemma:
I have a number of reports that are part of a Oracle package. They return an SQL Query back to a reports region on a page. I am having to deal with the column names returned are col01, col02..
The issue I have is, when building the Application Level query to download the XML sample from in building RTF layouts in Word, you can not use this code, you MUST use a standard SQL Select.
I have taken the sql from the function returning sql, and copied into the application query, supplying the required data values for bind variables being used in the query.
An XML file is produced, and I use this to build the RTF format file that I load back into APEX and try to use it for the PDF rendering of the report. I can view the output as a PDF in the Word add on, but when I try using it with the report, it is returning an empty PDF file.
Can anyone tell me what error log files on the bi publisher side I can look at to see what error is happening?
Thank you,

Tony,
You can find the log as follows:
- go to http://[yourserver]:[yourport]/em
- logon to OC4J EM: oc4jadmin/[yourpassword]
- click on "logs" at the bottom of the page
- in the hgrid/tree, expand OC4J->home->Application
xmlpserver
- click on view log icon
You can also observe what's going on in BI Publisher
by going to the command prompt from where you started
it.
Or, as a third option, you can locate the file on
your file system, depending on your setup, the path
would be something similar to this:
\oracle\product\10.2.0\bip\j2ee\home\application-deplo
yments\xmlpserver\application.log
With that said though, I don't expect you'll find
much in there that would help with your particular
problem. I suspect you either get no rows in your XML
at runtime, due to some session state issues, or your
XML structure does in fact not match your RTF
template.
I'm not quite following your problem description,
i.e. when did you do what and are you associating
your report layout with a report query or report
region. So just some general notes, your query needs
to be parseable at design-time, when exporting the
XML, so that you get the XML file with the proper
column names derived from your query. If you want to
use your RTF template with a standard report region,
you must export the XML file first using the advanced
XML structure option. And of course the column names
in your report query need to match the column names
in your report region.
Perhaps this helps you further diagnose what's going
on, if you have additional information that could
help, let me know. And if you could stage this on
apex.oracle.com, I'd be happy to take a look.
Regards,
MarcMarc,
Thanks for looking at this issue. Below find my remarks to your questions..
Re: your query needs
to be parseable at design-time, when exporting the
XML, so that you get the XML file with the proper
column names derived from your query.At the start of this process, the query code was a function in a package. The function was returning an SQL select statement, for a report region on a page. I took the select statement, built an application query to build a sample of the xml for BI Publisher desktop (Add-on for Word). The code was producing the usual Col01, Col02.. since at design time that is were the column names.
When I then took the xml from this and built the rtf for loading into my APEX application.
When testing the Application Query with this RTF report layout, I am getting PDF's. When using it with the report region sending an xml feed to BI Publisher I am getting nothing back.
I have since taken the sql code and moved it back into the report region, and set the region to have a type of straight SQL Query. I have even tried to hard-code the parameters I was getting from the page to limit data returned.
Is it possible to see the xml being produced by the APEX page?
Re: Stage this on apex.oracle.com.. I would love to, but we would have HIPPA issues if I posted the data on a public website.
Can I send you the RTF file and the xml file that the application query is creating to see if there something weird about them?
Thank you,

Hi ,
Can you elloborate a little bit more.
what i understood is that
When you use a sql query like select emp_add from XY
And IF emp_add contains more then 1000 chracters then you are not able to see the full data on the report or on a column
Is it the case or are you looking into some other aspect.
Can you ellborate a bit , Do you receive an error ?

Passing a string into an SQL query IN statement

Hello,
I need to connect to a database to pull some data to dynamically create a form based on the data I pull back. My SQL query works fine when I manually run it through a SQL client tool, but when I try to pass it through my workflow I'm having trouble with passing my string into the IN part of the statement. So if for example my SQL query is:
SELECT Field1, Field2, Field3 FROM Table1 WHERE Field4 IN (?)
I have a process variable that has the string I'm trying to pass into the ?, but I don't seem to be able to get the query to run. I have tried setting up my query to run as a Parameterized Query (passing my string process variable into the ?), and by setting the query up through xPath (where I am calling my process variable with an xPath declaration), but am not having any luck.
The process variable I am trying to pass is formatted such that I'm passing 'Value1','Value2','Value3' but I can reformat this string if need be. Even with using test data I can't get the query to return anything. For test data I have tried: 'Value1','Value2','Value3' ; Value1','Value2','Value3 ; Value1,Value2,Value3 but the query never returns any data. I can't seem to see how to format the string to pass into the query. The Query will work with a single Value in the test data, but as soon as I try to pass multiple values within the string it fails. Any suggestions?

The problem looks to be a limit on what I can pass into the SQL query component. My string is coming from data returned from another database. I take the xml output from that database call, pass it through a set variable component to remove my xml tags from the string, and then format the string in a script component (I have to do it this way because of the way the data coming out of my first database call). I've put in loggers, and can see that the string I'm passing into my query that is giving me problems, is formatted the same way as if I were to use the concat function Scott listed above. It looks like there is a limitation on what can be passed in my variable. I have tried creating my entire SQL query statement in a set variable component, and then just calling the process variable that holds that statement, but there is a character limit of 128 character for what can be passed in a variable through xpath in the SQL query component.
The next thing I tried was changing my SQL where clause. Instead of passing my variable directly into the IN statement I set up a PATINDEX('%:'+countyname+ ':%', ?) > 0 call to check for the values in my database call. As you can see I took out the "," that I was passing as part of my string, thinking that the SQL component was getting confused by them, and placed ":" characters around my values being passed in my string variable. No matter what I try to do though I'm not able to get the query to run. The component looks like it is taking my string, and is seeing the whole thing as a string instead of passing it as individual values within a string.
I think I'm getting close, but I keep getting a Content not allowed in prolog exception in the server logs.

SQL Query works in SQL Developer, but not always in MII

Hi all,
I encountered a strange behaviour with a query in MII 12.0.2. Maybe someone has a guess what happens.
I have created a SQL query which runs against Oracle 10g tables. I have tested the query using SQL Developer, and it throws a couple of lines, depending on the contents of the where clause.
Next I have copied the query to a MII SQL Query (FixedQuery). However, the output is empty most of the time, without showing any errors. After some testing I got the impression that older data are not displayed, but there is no time or date setting in MII.
As the SQL Developer always returns rows, I am unsure where to search for the error.
Regards
Michael

Michael,
I would imagine that you have sub-select statements in your FixedQuery, all which will fall subject to the RowCount property of the query template (SQL defaults to 100), which is issued through the driver and typically honored by the database when returning the data from your request.
Most of the native database query tools allow you to make unbound query requests with no limit on rows, which would probably account for the difference between SQL Developer and the query template.
For SQLServer it's ROWCOUNT: http://msdn.microsoft.com/en-us/library/ms188774.aspx
For Oracle it's ROWNUM: http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html
So the answer would be not to make the query template row count some rediculous number, but more appropriately refine the way that the database request is issued.

Jeremy

It looks like the query string you are trying to pass back exceeds the 32K limit for a varchar. Where this is happening is kind of difficult to tell as it could be any number of points, and also depends on what you are passing into the process via page items.
I would first try to establish what combination of page items causes this error to occur. Then, starting from the bottom and working your way backwards, I would start 'switching off' some of the items you use to build your query until it breaks again, thus establishing which part is leading to the error.
Also, I'm not sure what :P10_STMT is doing (are you maybe using this for visiblity of the query created)?

Using WHERE command in property loader SQL query

Hello All,
Hopefully this will be a fairly straight forward question.
I am attempting to use Property Loader to read in test limits from a SQL database. There are many types of models that need to be tested, each having a unique set of limits. I want to be able to retrieve the appropriate limits for the model of product under test.
To do this I have the product model number available in a FileGlobal. The database contains a table with the test limit information with an identifying 'ModelNumber_Number' column.
I have written the following SQL query achieve this:
"SELECT * FROM TESTLIMITS WHERE ModelNumber_Number=+ FileGlobals.ModelNumber"
However, this is where I am confused. I'm not sure on the syntax for accessing a variable in the SQL command. I receive the following error:
The multi-part identifier "FileGlobals.ModelNumber" could not be bound.
Can someone please provide guidence on how to do this?
Many thanks,
Cam.
Solved!
Go to Solution.

Thank you very much for your reply.
Upon changing the query to as you suggest, I am presented with the following:
Error In SQL Statement Expression. "SELECT * FROM TESTLIMITS WHERE ModelNumber_Number = " + FileGlobals.ModelNumber
Specified value does not have the expected type.
The type of FileGlobals.ModelNumber is a numeric represented as a double precision 64 bit signed integer.
The database column is also of type int 64.
Can you suggest a solution?
Many thanks.

SQL Subscription field shows * only with Dynamic Text Label in SQL query

We are using Hyperion Analyzer 7.2.x for showing budget and actual data. I have to show this financial data based on the security e.g. person in IT can see only IT dept. data. Hence I want to use dynamic text label <<userid>> for the security based on the person logging in to Analyzer.
But when I use dynamic text label <<userid>> in the SQL query in SQL Spreadsheet, SQL Subscription field shows * only selection option. Does anyone have idea how to solve this problem?
Thanks in advance for your help.
-SV

Hi
Okay i know this is a bit crazy way.....but i think this is the solution for your issue.
Create a report without the where clause (<<useris>>) then add a filter (sql subscription) then you can find all the values that are there in the SQL field (try to increase the query limit it is set to 250 as default) then edit the spreadsheet and add the where clause (<<userid>>).
This will help you having the filter and the dynamic text label. I think there is an issue when you try to filter it with a where clause.
Hope it helps.

Where rownum=2 in my sql query is not working . Why ??

Hello,
i am using Oracle 11g .Referring scott schema's emp table.
I just issued this sql query with the intention to get second highest salary of a employee. But i am unable to understand why my query fails ?
select rownum,empno,ename,sal from (select empno,ename,sal from emp order by sal desc) where rownum=2;This query is returning no rows . Can you tell why this query is returning no rows ?

888953 wrote:
Because you can use ROWNUM only to limit the number of returned records, not to return a specific record.
So only this has sense (n any number):
ROWNUM <= n
or
ROWNUM = 1 (which is equal to ROWNUM <= 1)
Anything else will not return a row.As i said ,
select * from (select rownum rn,empno,ename,sal from (select empno,ename,sal from emp order by sal desc)) where rn=2;this query is working fine.So rownm can be used to return a specific record . Please rectify me if i am wrong .

Using prompts with SQL query

Post Author: wleonetti
CA Forum: Crystal Reports
Hello!
I have acquired a report from our regional headquarters, and have been asked locally to add a prompt to one that already exists in the report.
The report currently uses an SQL query, which in turn uses a single prompt to limit the data reported. However, the name of the parameter in the Field Explorer in Parameter Fields is "Facility", but, when I use the Database Expert and select edit for the query (under Selected Tables, right-click on "Command" under the database and click on "Edit Command"--is Command a default name?), under the Parameter List, the name of the parameter there is "Facility1" (?). The SQL references the parameter "Facility1" (...like '{?Facility1}'), but I cannot find any link/interface between the Parameter List "Facility1" to the Parameter Field "Facility", and I cannot find any other references to "Facility1" anywhere else in the report (sorry, I'm very new at CR, and am not sure how to do a global search of a desired text string in the reports).
I have asked the author for an explanation, but he would only offer, after indicating that he ... was not obligated to help me in any way .., the following bone: "I just simply rename the parameter in Command from Facility1 to Facility which bears the same name as the parameter interface and it just works fine." This only served to confuse me more, since the parameter name currently in Command is "Facility1" (and the report works the way it is)--when I change the name of the parameter in Parameter List (and the parameter name in the SQL query) to "Facility" (to match the Parameter Field's "Facility"?) ... the parameter in the Parameter Fields ... disappears?
Can someone please instruct me how to, in whatever steps are necessary, add a parameter to the Parameter Fields and edit the SQL code to use that parameter? or point me to some documentation that will help me with this?
Thanks in advance for any help offered.

return functionname(to_date('30-sep-2010', 'dd-mon-yyyy'));
end;That works fine for me, and if I take out the begin-end and the trailing semicolon from the return statement I get the same behavior as you.
It does mention in the help for the source (only during the wizard though) that this source type has to be expressed that way, but I agree it would be helpful if the tool would validate for this format when 'Function Returning SQL Query' is used or give some sort of indication of the trouble. Anyway, this should get you going again.
Hope this helps,
John
