Precompilers, OCI & OCCI :: Data Loading Of French Input File
Aug 16, 2012
I am trying to load a input flat file (french data in it) into the database using pro*c (not using sql loader because of some validations ). i am reading the line by line and populating it into the structure and then process it.
The input file is encoded in WE8ISO8895P1 , I want the records to be populated into a table. so i did set NLS_LANG=French_France.WE8ISO8895P1 and ran the pro*c program . i used character host variable in the insert query , i used data from the earlier read structure and set these character host variable.
The problem i am facing is , when i am printing the values before insert i could see correct data.
For example the printed data of variable is "pas de donné " and strlen is 14. the target table field is of varchar type
( name varchar(20 char) )
but after i insert i could see only the truncated value in the database i.e "pas de donn" in the table length is 11.

I have 3 code files written in ProC. I have precompiled, compiled, tested them in my local environment (Windows) & they work fine. But when I try in real environment, AIX 5.3, I can precompile them. But when I try to compile & link them with the libclntsh library I get errors. I am using a Makefile but just for testing this is the command -
xlc oraProcs oraProcs.c test_curva.c lib_util.c -I $ORACLE_HOME/precomp/public -L $LIBPATH -l libclntsh.a
Error - ld: 0706-006 Cannot find or open library file: -l libclntsh.a
ld: open(): A file or directory in the pathname does not exist
where LIBPATH = $ORACLE_HOME/lib
library libclntsh.a exists in $ORACLE_HOME/lib & has the right permissions
I also tried removing the library libclntsh.a & recreating it using the command - genclntsh When I run this command I get this warning more than once -ld: 0711-783 Warning TOC overflow TOC size: 66888 Max size: 65536 genclntsh creates the library libclntsh.a, just not sure if these warnings damage the library file and are related to my link erros in some way.

We are migrating a proc application as described below.
Old Env: UNIX
Old DB: Oracle 8i
New Env: Linux
New DB: Oracle 11g
New modules are successfully compiled in Linux environment. But we are facing issues in writing the output of VARCHAR datatype to a file.
find below the extract of code.
EXEC SQL BEGIN DECLARE SECTION;
varchar mcolmnvarchar[4];
EXEC SQL END DECLARE SECTION;
EXEC SQL DECLARE crs CURSOR FOR
SELECT NVL(colmn,' ') FROM table1
memset(mcolmnvarchar.arr,'�',4); //Was added for only Linux migration. Not present in unix env.
EXEC SQL FETCH c1 INTO :mcolmnvarchar;
cout << "Data at Stage one"<< mcolmnvarchar << endl;
mcolmnvarchar.arr[mcolmnvarchar.len]='�';
cout << "Data at Stage two"<< mcolmnvarchar << endl;
fprintf(fptr,"%-4s",mcolmnvarchar.arr);
Above code works absolutely fine in Unix env with Oracle 8i. But with Linux env & Oracle 11g it is not working. No compilation or run time errors. Data at Stage one prints the output of database properly. But after null terminator code, Data at Stage two statement prints without any value. Value is lost after null terminator code.

I am seeing some trailing characters in the coloumn when we are inserting Blob. I am doing SQLBindParameter with SQL_C_BINARY and SQL_LONGVARBINARY as InputOutputType and ValueType respectively.Do you see any problem in this. I get this problem when I am running Oracle 11 g client on an Windows 2008 Server 64bit.When the same set of query is fired from Windows 2003 Server 32bit with Oracle 10g it works fine and no trailing character gets inserted.

I want to insert XML data into my ( Oracle 11G Release 1 ) XMLType table using OCCI. I'm getting
ORA-01461: can bind a LONG value only for insert into a LONG column
My XML data size is around 1.5 to 2MB. I have also tried using setMaxParamSize before calling the setString method. But, still I'm getting the same exception.
How to resolve this issue?

I've recently been asked to replace certain English text fields with their French translation. I thought I could do this with the replace function: line_desc_reformed := replace(l.Line_Description,'Labor Item for Regular Hours','Main d uvres pour les heures rgulire');
The special characters do not get translated. So I tried the CONVERT function: line_desc_reformed := CONVERT(line_desc_reformed, 'WE8MSWIN1252', 'WE8DEC').
All gets translated except for the tick mark after the d. It gets replaced by an upside down? I have tried several different language sets and can not get that to convert.
also when using the dbms_xmldom to convert this to xml, the also gets replaced by an upside down ?. I don't belive you can change the charset when using this package.

Iam using Oracle client 11g(32 bit) and Oracle database 11g on Unix server.
I have the created the following procedure to load XML file located in TEST_XML oracle directory( which is mapped to
DB/bulk01/REFLIB/REFDV/LOAD_XML) on the server.
Create or replace procedure TEST_LOAD_XML IS
dest_clob clob;
src_clob BFILE := BFILENAME('TEST_XML', 'arenas.xml');
dst_offset NUMBER := 1;
src_offset NUMBER := 1;
lang_ctx number := DBMS_LOB.DEFAULT_LANG_CTX;
warning NUMBER;
[Code]....
when I execute the above procedure I get ORA-22288 file or LOB operation FILEOPEN failed No such file or directory error.
Looks like it did not find my oracle directory 'TEST_XML'
do I have to do anything like mapping? if so since my database is on unix server how do I map?

I 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?

My program needs to connect to two databases and make operations in both databases:
Quote:connect to db1;
connect to db2;
select from table in db1;
update table in db2;
i would like to know whether it's possible, and how to do it ? how to specify for each query the database connection to use?
note that I can't use dblinks as i don't have enough access rights and privileges on neither of the databases.

My OS is Linux and I installed Oracle 10.2. Everything is fine.I can use sqlplus, exp, imp etc with no problem.Now I have created another linux user test in /home/test. I unzipped basic-10.2xxxxxx.zip (/home/test/instantclient_10_2) and exported LD_LIBRARY_PATH.I guess I have installed instant client in this way.
My testOra.cpp:
#include <occi.h>
int main()
{
return 0;
}
This test.cpp would not compile. It cannot find occi.

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 can test the NULLness of the pServiceRecord->itemTo value and set the indicator ind_dbToDate to -1 but I don't know how to incorporate this with the to_date syntax (if I can)?
EXEC SQL BEGIN DECLARE SECTION;
char dbFromDate[MAX_DATE_LEN];
char dbToDate[MAX_DATE_LEN];
short ind_dbToDate;
