View 2 Replies View RelatedI am trying to give back data from a stored procedure written in C. I registered the functions as follows:create or replace procedure version(versioninfo OUT clob) as external name "version" library myLib language c with context parameters (context, versioninfo, versioninfo INDICATOR SB4); It compiles fine. The function being called look like this:
extern "C" DLLEXPORT
void version(OCIExtProcContext* context, OCILobLocator **out, sb4 *ind_out){
OCIEnv* envh;
OCISvcCtx* svch;
OCIError* errh;
OCIExtProcGetEnv (context, &envh, &svch, &errh);
std::string versioninfo = "104";
oraub8 maxChar = 10;
[code]...
If I execute the procedure with SQLDeveloper by pressing "play" it is getting executed but there is no result. If I try to execute it from an anonymous block it results in ORA-22275 instead of doing anything.
declare
res clob;
begin
-- the following doesn't work much
--dbms_lob.createtemporary(res,true);
version(res);
dbms_output.put_line(res);
end;
Actually I have to questions:
1.) Why does Oracle give me the error? In my opinion all requirements mentioned by the error description are met.
2.) Why is there no output when executing the function via SQL Developer? Is the usage of OCILobWrite wrong?

I declare a cursor for a table with 8000 records, when I fetch the cursor this message appear ORA-03113: end-of-file on communication channels when the fetch reach the 6500 element, What is the problem here?. All data are ok, not null fields.
other problem
How I can reuse a cursor, I declare a cursor for a table where code_part = 300, then I fetch all elements until end cursor, then I close the cursor, Then I declare the same cursor again for the same table where code_part = 359, but it is not successful, when I tried to fetch the cursor again the cobol program show me the last record for the first code, How I can restart the cursor or delete it or freed the cursor position?

If doing an insert into DATE type fields like below... how do I employ null indicator values with the TO_DATE sql to cope with NULL values for the End Date?

I am using dynamic Pl/SQL with ProC and having problems with cursor. I've to execute stored procedure dynamically and get the result of select list into the cursor. The EXECUTE command is working fine but the FETCH gets failed with error "ORA-01002: fetch out of sequence". I've read that cursor variable can not be used with dynamic SQL.
Stored Procedure:
------------------
ROCEDURE open_mod_cur (
curs IN OUT cur_type,
module_id IN varchar2)
[Code].....
I use a cursor to select records from a database table into a C structure as follows...
{
int iLoop = 0;
int iResult = 0;
[Code]....
The otc_multiplier field is NULL. As is the to_date sometimes. However, when I output the records later, the entries where the to_date is NULL come out fine (no value). But the otc_multiplier is getting output as 0.0 using...
// this is output later in another fuction using the following..
sprintf(newRecord, "%.1f",daServiceRecs->itemMultiplier);
If using c structures in this manner, what is the method for ensuring that numeric values are set to NULL when required?
I have Multi-threaded application using pro*c to connect to oracle.
I am using the following piece of code to create a connection to oracle database and preserver the context of created connection.
struct sqlca * tempSqlca = new sqlca;
struct sqlca & sqlca = * tempSqlca;
EXEC SQL BEGIN DECLARE SECTION;
SQL_CONTEXT localContext;
[code].....
I am using the following piece of code to close the connection to the oracle database, I am using the context created in the previous step and passing it to the below code(connection.context)to release the connection.
if (connection.context == 0 || connection.ca == 0)
return true;
// Multithreading: get the communication area of the context
struct sqlca & sqlca = *(connection.ca);
EXEC SQL BEGIN DECLARE SECTION;
[code].....
When the above code is executed there is no exception thrown but the connection is not getting close. I am using the V$SESSION system views to monitor the connection created.
I there anything I am missing in my code for the connection closing to fail.
I am receiving the following error while inserting records.
"Oracle Error:ORA-12899: value too large for column "MFG_ADMIN"."GAGE_RESULTS"."COMP
whereas I am checking the length of all values before inserting and am sure that none of them are larger than column lengths.I did some research and found this error might be due to character set.
select * from nls_database_parameters where parameter like '%CHARACTERSET';

how can this be related to my problem or if something else is causing this error.

tried " printf("from select sqlstmt %s

View 6 Replies View RelatedI am back with one more issue. I am fetching records through a cursor from database using Pro*C and inserting some records as shown below:
EXEC SQL DECLARE cur_num CURSOR FOR
SELECT STUDENT_NUMBER

ORDER BY STUDENT_NUMBER;
EXEC SQL OPEN cur_num;
EXEC SQL WHENEVER NOT FOUND DO break;
[code]....
This code works fine sometimes but ends up with this error sometimes: ORA-01002: fetch out of sequence and also do I need to do null termination once i fetch data from the database like this:
Quote:EXEC SQL FETCH cur_num INTO :std_num ;
std_num.arr[std_num.len] = '�';
std_num is declared as varchar datatype.

We intermittently get ORA-1403 NO DATA FOUND and ORA-01405 FETCH COLUMN VALUE IS NULL errors. However, the data does exist and the columns are set as not null. If we run the proc manually then it works fine.
We have only recently switched to using RAC (2 instances).

I've a Pro*C program which fills various large tables (in different schemas). I am executing the procedures which fill the tables as PThreads (since I want them to run in parallel for performance reasons). When I execute all threads sequentially (pthread_join(last_thread) before every pthread_create(next_thread)) everything works fine. But when a run the threads in parallel (as they should run), I am getting: "ORA-24550: signal received: si_signo=11si_errno=0si_code=1si_addr=0x18 Aborted"
