Why OCIEnvCreate function return -1

Hello,everyone. Now I use VS C++ 2005 (with sp1)and OCI that in ORACLE 10g to develop a application.
calling OCIEnvCreate failed when connect the Database. The return value is -1. My Pataner saied, I cannot use OCIErrorGet() to get the error informaintion,becase The Environment isnot initialed.
But I can connect Database by using ORACLE 10g Client in my mathine(Input the same username and password).
Why OCIEnvCreate function return -1?

VC++ 2005 has some known incompatible issues with 10g DLLs. Either downgrade the oracle client or upgrade the VC++ version and try. Hope $ORACLE_HOME env are set in your system.

Why oracle function return 4000 characters ?

Dear All
When I write any function to get some return value in a query, its width is set to 4000. Moreover, when i write the same query to create any LOV, it gives an error that record group field cannot be greater than 2000. Where the actual width of this field is 200 characters.
Why function always returns 4000 characters?
Regards
Edited by: OraLearner on Dec 1, 2010 11:47 AM

Because the maximum of a varchar2 in SQL is 4000 and you have no dimension in your function:
SQL> r
1 create or replace function myfunc(inMaxVal in number) return varchar2 is
2    vRet varchar2(32000);
3 begin
4    for i in 1..inMaxVal loop
5      vRet := vRet || '1';
6    end loop;
7    return vRet;
8* end;
Function created.
SQL> select myfunc(4001) from dual;
select myfunc(4001) from dual

1111111111111111111111111111111111111111111111111111so the SQL Engine have to assume your function returns 4000 bytes. If you use this function in PL/SQL it can be up to 32767 bytes:
SQL> r

Why getScale() function returns 0 ?

Hi,
I have a query which selects sum(amount) .
If i call rs.getDouble("sum") , it returns me proper double value
as 2000.50.
But the following code gives only Long value as 2000
ResultSetMetaData rsmd = rs.getMetaData();
if (rsmd.getScale(1) == 0)
double value = rs.getLong("sum");
else
long value = rs.getLong("sum");
Can anybody tell me why getScale() returns 0 ?
Is there any other way to find out whether value is double or long?
thanx in advance,
Sulabha

This sounds to me, firstly, as a Driver implementation
issue. I would check the documentation of the driver
first.
Also, there is ResultSetMetaData.getPrecision() method
which may be implmented to let you know how the number
is structured.
I tried with getScale() and getPrecision() methods both.
They work properly for any field of datatype NUMBER but if i use Group function like SUM() , then they return Zero.
Can this be a driver problem?
public static int getScale(ResultSet rs, String
field)
int scale = 0;
String temp = rs.getString(field);
if(temp.indexOf(".") != -1)
scale = temp.substring(temp.indexOf(".")).length();
return scale;
}Yes....this will work definitely.
Thanks,

Hi,
follow the below procedure for auto number generation.
From SNRO create a custom no. range object. When creating it specify
Short, long text,Number length domain (Ex: NUM5) and Warning % (Ex:
10.0.).
After creating it maintain the intervals by clicking the button
Number Ranges from the 1st screen and in the next screen press
change intervals and then maintain the intervals (From number, To
number, Current no etc.).
Now u can use this no. range object with the FMs, those I mentioned
in my earlier reply.
You can maitain a number range object from tran. SNRO and can
fetch
the next available no. using the FM 'NUMBER_GET_NEXT'.
Also check the FMs below for further operations on number range.
'NUMBER_RANGE_OBJECT_READ',
'NUMBER_RANGE_INTERVAL_LIST'
'NUMBER_RANGE_OBJECT_LIST'
'NUMBER_RANGE_OBJECT_GET_INFO'
Reward if useful,
Thanks,
Sreeram.

Why does the InitVXIlibrary function return -32768 ?

Why does the InitVXIlibrary function return -32768 ?

Hello,
It would be extremely helpful to see a log of what is happening "behind the scenes" with the driver. To do this, you can use a utility called NI-Spy which can be launched from Start >> Programs >> National Instruments >> NI Spy or from the Measurement & Automation Explorer (MAX) utility.
NI Spy is a Win32 application that monitors, records, and displays National Instruments API calls made by applications. Use NI Spy to quickly locate and analyze any erroneous National Instruments API calls that your application makes, and to verify that the communication with your instrument is correct.
You can turn the log to file feature on via the Spy >> Options menu in the program. Please attach this log file to this Developer Zone post
so that we may further help you.

Why does getdate() function return same time value for multiple select statements executed sequentially

When I run the following code
set nocount on
declare @i table(id int identity(1,1) primary key, sDate datetime)
while((select count(*) from @i)<10000)
begin
insert into @i(sDate) select getdate()
end
select top 5 sDate, count(id) selectCalls
from @i
group by sDate
order by count(id) desc
I get the following results.
sDate selectCalls
2014-07-30 14:50:27.510 406
2014-07-30 14:50:27.527 274
2014-07-30 14:50:27.540 219
2014-07-30 14:50:27.557 195
2014-07-30 14:50:27.573 170
As you can see the select getdate() function returned same time up to the milisecon 406 time for the first date value. This started happening when we moved our applications to a faster server with four processors. Is this correct or am I
going crazy?
Please let me know
Bilal

Observe that adding 2 ms is accurate only with datetime2. As noted above, datetime does not have ms resolution:
set nocount on
declare @d datetime, @i int, @d2 datetime2
select @d = getdate(), @i = 0, @d2 = sysdatetime()
while(@i<10)
begin
select @d2, @d, current_timestamp, getdate(), sysdatetime()
select @d = dateadd(ms,2,@d), @i = @i+1, @d2=dateadd(ms,2,@d2)
end

Report- Pl/sql function returning sql query parsing page items as text?

Hi Team,
I am facing a strange issue .
I have four page items namely
1)JOB_CODE
2)MIN_EXP
3) MAX_EXP
4) SOURCES1
I have a report of the type "Pl/sql function returning sql query"
declare
v_sql varchar2(4000);
begin
if (:JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql:= 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:JOB_CODE IS NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MIN_EXP IS NULL and :JOB_CODE IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years <= :MAX_EXP and V_REQUIREMENT = :JOB_CODE and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MAX_EXP is null and :JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
end if;
insert into query_list values (v_sql);
insert into debug values (:JOB_CODE , :MIN_EXP , :MAX_EXP , :SOURCES1);
return v_sql;
end;
Please not that I am insertin the query into a table called Query_list and the page item values into the table called Debug thru the pl/sql function which returns teh query.
Now I select the data from the debug tables.
select unique(query) from query_list;
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like '%:SOURCES1%'
select * from debug;
JOBCODE MINEX MAXEX SOURCE
21 1 10 donkeyHire
And if I run the query in sql I get some records returned
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = 21 and v_experience_years >= 1 and v_experience_years <= and source like 'donkeyHire'
V_CANDIDATE_ID V_FNAME V_CURRENT_EMPLOYER V_EXPERIENCE_YEARS
2 Vengu Andale Tech 4
But the record does not show up in the report!
does this type of report parse page items as text?
Why is it so?
Waiting for an early reply.
Thanks,
venkat

Venkat - You don't want to put ':SOURCES1' in quotes like that.

On Submit process not firing -report (PL/SQL function returning SQL query)

Can anyone suggest possible causes / solutions for the following problem?
I have a report region that uses a PL/SQL function returning SQL query. The report allows the user to update multiple fields / rows and then click a button to submit the page which should run the On-Submit process to update the database. However the process does not run and I get a 'HTTP404 page cannot be found' error; and when I navigate back using the Back button I cannot then navigate to any other page in my application without getting the same error. The button was created by a wizard selecting the options to submit the page and redirect to a (same) page. The button does not actually have a redirect in its definition but the wizard created a branch to the same page which should work and the button has the text 'submit as SUBMIT' next to it so it appears to be set up correctly.
I have recreated this page several times in my application and I cannot get the On-Submit process to run. However I have created a cut down version of the same page in the sample application on apex.oracle.com at http://apex.oracle.com/pls/otn/f?p=4550:1:179951678764332 and this works perfectly so I am at a loss to understand why it does not work in my application. I cannot post any part of the application itself but if anybody would like to check out page 30 of the sample application (Customer Update Test tab) updating the surnames only, using credentials ja, demo, demo this is pretty much what I have got in my application.
Any ideas would be much appreciated?

Thanks for the suggestions guys. I have now identified that the problem goes away when I remove the second table from my report query. The original report query retrieved data from two tables and the process was updating only one of the tables. I thought I had approached the task logically i.e. first get the report to display the records from the two tables, then get the process to update the first table and finally to modify the process further to update the second table.
Can anyone point me to an example of multiple row updates on multiple tables using a PL/SQL function returning an SQL query?

Can oracle function return more than one value

Hi All
please answer can oracle function return more than one value
need one schenario
regards

Can any function, irrespective of the language, return multiple values?
OF COURSE NOT!!
So why do you think Oracle will now suddenly do it differently than all other languages? Never mind that it is impossible for a function (a unit/module of code) returning a memory address, to return multiple memory addresses. The machine code that does that, has not been yet been designed/implemented.
I am continually amazed that this question is asked. It is about something so fundamental in almost every single 3rd and 4th generation language... something that is taught right at the start... the definition of what a procedure and what a function is.
Sorry, but I simply cannot pull punches on this subject and smooth it over. There is something fundamentally wrong with your training as a programmer if you have to ask such a question about a function.
And whatever programming skills you build on such a foundation, will be seriously lacking.
I kindly suggest that you get back to the very basics of programming - and review and revisit until you fully understand it. There are no shortcuts in becomming a good programmer.

PL/SQL function returning a colon delimited list of headings

Hello,
Apex version 4.1.0.23. I am editing an existing classic report which has the column heading option set to 'PL/SQL function returning a colon delimited list of headings'. I have been looking for some time but I cannot find where this PL/SQL function is defined. Can any one point me to the right direction? I do not see anything in the documentation either.
Thanks,
Usman

Hi Usman,
I looked into this issue and found that there's some JavaScript code executed when opening the page with the PL/SQL headings option enabled, or when selecting that option after loading the page, and this JavaScript attempts to set a background color for the column heading fields. Since we only display attributes for up to 100 columns, this JavaScript fails once you have more than 100 columns.
I would certainly agree with Tony that 60 or 100 columns are a bit much. But there should be some indication why something is not working, even if it's only a message stating that there's only a certain number of columns supported. So I'll log a bug to improve this in APEX 5.0.
Thanks,
Marc

Note: This problem is seen only in our 64bit application. However, in 32bit
SQLExecDirectW and SQLExecute functions return successfully.
As we could not find the values of 6th, 9th and 10th arguments(ColumnSize,
BufferLength, and StrLen_or_IndPtr) passed to
SQLBindParameter in the ODBC traces for 64bit, we are not sure whether the values for the above mentioned arguments are received correctly by SQLBindParameter or not. This information would help us to debug further. So, could you please let us know why
these values are not displayed.
1)Here is the extract of the SQL.log file for 32bit where the values for SQLULEN , SQLLEN and SQLLEN* are displayed properly:
PR0CNFG 1028-15f0 ENTER SQLBindParameter
HSTMT 0x006FBDD8

SWORD 1 <SQL_PARAM_INPUT>
SWORD -8 <SQL_C_WCHAR>
SWORD -9 <SQL_WVARCHAR>
SQLULEN 23
SWORD 0
PTR 0x0595EBBA
SQLLEN 46
SQLLEN * 0x05A5FB00
2)Here is the extract of the SQL.log file for 64bit where the values for SQLULEN , SQLLEN are not displayed properly and
SQLExecDirectW function return error:”DIAG

PR0CNFG a78-fe4 ENTER SQLBindParameter

Hi Nalsr,
From my research, I found:
"[Microsoft][ODBC SQL Server Driver]String
data right truncation" error may be returned from a call to
SQLBindParameter if the size of the string parameter being used is greater than the size of the column being compared to. In other words if the
string size of the <expression> to the left of the <comparison_operator> is less than the
string size of the <expression> to the
right, ODBC may return this error.
The resolution is to make the string size of the <expression> to the
right of the <comparison_operator> less than or equal to the
string size of the <expression> on the left.
It is difficult to track down this type of problem when third party development applications are being used. ODBC Trace can be used to help determine if this problem is occuring.
Here is an example where the customer has submitted a query "select count(*) from type1 where type1 = ?", type1 is varchar(5) and the
data type being passed by the application is char[9].
Here is the relevant portion of the trace. The following information from the "exit" of SQLDescribeParam
SWORD * 0x0095e898 (12)
UDWORD * 0x0095e880 (5)
Maps to the following with the actual value in parenthesis - SQL_VARCHAR Size 5:
SQLSMALLINT *DataTypePtr
SQLUINTEGER *ParameterSizePtr
The "exit" value from SQLBindParameter provides the following
information:
SWORD 1 <SQL_PARAM_INPUT>
SWORD 1 <SQL_C_CHAR>
SQL Data Type SWORD 12 <SQL_VARCHAR>
Parameter Size UDWORD 5
SWORD 0
Value PTR 0x0181c188
Value Buffer Size SDWORD 5
String Length SDWORD * 0x0181c103 (9)
The string length parameter is the length of the
string being bound to the parameter, in this instance there is a size mismatch which results in the SQLError and the SQLErrorW with the message "[Microsoft][ODBC SQL Server
Driver]String data
right truncation" .
Hope this could be helpful.
Best regards,
Halin Huang

Unable to see function return values in Visual Studio 2013 debugger

Hi!
I can't see function return values in
Microsoft Visual Studio Ultimate 2013
Version 12.0.31101.00 Update 4
Microsoft .NET Framework
Version 4.5.51650
Installed Version: Ultimate<o:p></o:p>
as described in http://blogs.msdn.com/b/visualstudioalm/archive/2013/06/27/seeing-function-return-values-in-the-debugger-in-visual-studio-2013.aspx
So what can I do to get this functionality back?

Hi MsdnMezzo,

If use the same sample in the above blog provided by you, how about the result? Could you debug it with the same steps? I could debug it in my side using the VS2013.
So to make sure that whether it is your VS IDE issue, please debug it with this sample, if it works well, I doubt that we would think about your specific project and the debugging steps.
If so, to really repro this issue, could you share us a sample with one drive? You could upload your project to one drive and share us the downloaded link in your new reply, I will download and repro this issue in my side.
Best Regards,
Jack

Page Validation - Function Returning Boolean - Check for NULL

I have 3 Page Validations which all fire on "When Button Pressed" = "Submit".
 
Number 1 is of type "Item specified is NOT NULL" for "P199_BUSINESS_UNIT1".
 
Number 2 is of type "Item specified is NOT NULL" for "P199_BUSINESS_UNIT2".
 
Number 3 is of type "Function Returning Boolean" and has the following code:
 
IF :P199_BUSINESS_UNIT1 IS NULL AND
 :P199_BUSINESS_UNIT2 IS NULL THEN
 RETURN FALSE ;
ELSE
 RETURN TRUE ;
END IF ; 
When P199_BUSINESS_UNIT1 is NULL and P199_BUSINESS_UNIT2 is NOT NULL, I get the Error from Validation 1. Perfect.
 
When P199_BUSINESS_UNIT1 is NOT NULL and P199_BUSINESS_UNIT2 is NULL, I get the Error from Validation 2. Perfect.
 
When P199_BUSINESS_UNIT1 is NOT NULL and P199_BUSINESS_UNIT2 is NOT NULL, I don't get an Error Message. Perfect.
 
When P199_BUSINESS_UNIT1 is NULL and P199_BUSINESS_UNIT2 is NULL, I get Error Message 1 & 2, but nothing from 3.
 
If I change the code to:
 
IF :P199_BUSINESS_UNIT1 = '01' AND
 :P199_BUSINESS_UNIT2 = '01' THEN
 RETURN FALSE ;
ELSE
 RETURN TRUE ;
END IF ; 
and change both values to '01', I get the appropriate Error Message.
 
What is going on? Is there some reason I can't check for NULL in a Function Returning Boolean?

Scott,
 
Instead of adding the Validations, I changed my code from:
 
IF :P199_BUSINESS_UNIT1 IS NULL AND
 :P199_BUSINESS_UNIT2 IS NULL THEN
 RETURN FALSE ;
ELSE
 RETURN TRUE ;
END IF ;
 to the following and got the desired results:
 
IF REPLACE(:P199_BUSINESS_UNIT1,'%null' || '%',NULL) IS NULL AND
 REPLACE(:P199_BUSINESS_UNIT2,'%null' || '%',NULL) IS NULL THEN
 RETURN FALSE ;
ELSE
 RETURN TRUE ;
END IF ; 
Note that I changed the word REPLACE to upper case and the second occurrence of the word NULL to upper case to accentuate the fact that the '%null' is case sensitive, using "%NULL' does not work, it has to be "%null' in lower case.
 
Thanks for your help.

Issue with running PL/SQL function returning Sql query

hi, I am trying to create a report region by using the option of PL/SQL function returning sql query.
I notice that it's very slow for the report region page to show up. In my PL/SQL function body, there are only 3 steps, first update all the 10 rows of varchar2 fields to null,then insert values to those fields, then select all from the table to show report results. It takes more than 5 minitues for the page to load up, how ever, if i run those steps in SQL*Plus, it only takes a couple of seconds to finish. Any suggestions?
Thanks,
gina

Sergio, the codes are as followed,
Declare
q varchar2(32767); -- query
Begin
q := 'select "ID",'||
'"ENTRY NAME","TOTAL","#CM","%CM","#CA",'||
'"%CA", from Info_table';
update info_table
set "TOTAL" = '',
"#CM" = '',
"%CM" = '',
"#CA" ='',
"%CA"=''
where "ID"<=10;
// set all data in column Total to null,there is only 10 rows in the table
update info_Table set Total = vTotal,
"#CM" = vCM
(those variables hold user key-in Text filed value)
where ID = 1;
return q;
End;

Why OCIEnvCreate function return -1
