Precompilers, OCI & OCCI :: Simple Program Compilation
May 11, 2009
I am trying to use OCIColl datatype and thus wanted to check if a simple program using OCI functions and data types gets compile or not. sO I wrote the follwoing function which I want to compile as a DLL.
extern "C" CLUSTERINGDLL_API OCIColl *fnClusteringDLL(OCIColl *dxm[])
{
OCIError *errhp;
OCINumber num_1, num_2, sum;
OCINumberAdd(errhp, &num_1, &num_2, &sum);
std::cout<<"Members in the array are "<<dxm[1]<<std::endl;
std::cout<<"2 Member in the array are "<<dxm[0]<<std::endl;
printf("Is this printed %f", dxm[0]);
return dxm[1];
}
But I am getting the following error:-
Error6error LNK2019: unresolved external symbol _OCINumberAdd referenced in function _fnClusteringDLLclusteringdll.obj...
I have included the library folder containing oci.lib in the project directories.
i need to compile a proc program, say prog.pc.have oracle 10g in my system. Since i am new to proc programming, me on the steps to compile the proc program in oracle proc compiler.
Linux 2.4.21-37.ELsmp #1 SMP Wed Sep 7 13:28:55 EDT 2005 i686 i686 i386 GNU/Linux...As you'll see I do not understand anything about PRO*C. I need to compile this PRO*C code to use it to retrieve DBMS PIPES being sent.
I'm trying to compile it using the following command: gcc -o IAPIPE IAPIPE.c
The code - file IAPIPE.c #include <stdio.h> #include <string.h>
EXEC SQL BEGIN DECLARE SECTION; VARCHAR username[20]; int status; int msg_length; char retval[2000]; EXEC SQL END DECLARE SECTION; [code]....
i am getting below error when i compiler a pro*c program with Oracle 10g client with IBM C compiler version 9.0 on AIX 6.1
Syntax error at line 183, column 2, file /usr/include/sys/socket.h: .... PCC-S-02201, Encountered the symbol "sa_family_t" when expecting one of the foll owing: ....
Above query runs perfectly on SQL prompt.Same query, when being run in a Pro*C program gives compilation error-:
Error at specified line:
,( SELECT D.V3 FROM TABLE2 D WHERE D.V3 = C.V4) .............................1 PCC-S-02201, Encountered the symbol "D" when expecting one of the following: ( ) * + - / . @ | at, day, hour, minute, month, second, year,
What are the possbile causes of error. I am using Oracle 10g on Unix.
I need to call a PL/SQL stored procedure from a C program. Something like this sample program provided by Oracle -
main() { int i; EXEC SQL BEGIN DECLARE SECTION; /* Define type for null-terminated strings. */ EXEC SQL TYPE asciz IS STRING(20); asciz username[20]; asciz password[20]; [code].......
The question is - how is the Stored procedure get_employees declared ? Or more specifically, how is the salary parameter declared in get_employees ?
I want write a program using oci to login into oracle database.Advance security option for the oracle server is set to kerberos authentication. Is it possible to login to the oracle database through olog() function.
Initial ticket is required in kerberos authentication. So is it also needed durinfg the login from my programme.
my Multithread-Program hangs in an oracle library while passing a prepare statement (also if i try an EXEC SQL SELECT statement...). Something seems to be wrong in the Program, but i cant's find the Error.The Program is build with:
java.sql.SQLException: ORA-04054: database link GMAIL.COM does not exist
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:331) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:288) at oracle.jdbc.driver.T4C8Oall.receive(T4C8Oall.java:743) at oracle.jdbc.driver.T4CStatement.doOall8(T4CStatement.java:207) at oracle.jdbc.driver.T4CStatement.executeForRows(T4CStatement.java:946) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1169) at oracle.jdbc.driver.OracleStatement.executeUpdateInternal(OracleStatement.java:1615) at oracle.jdbc.driver.OracleStatement.executeUpdate(OracleStatement.java:1580) at com.jdbc.pack.Lab1.main(Lab1.java:31)
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:
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 am trying to describe an STP in a package, but it gives me an error.
e.g. In package ABC suppose there is an STP XYZ, I am trying to describe ABC.XYZ function but it gives me an error code 4043 and error message object XYZ.ABC does not exist.
in my oci applications,if i get a column of number that is in the scope of int,i can use value = *(int *)field.data; get the value,but if the column size is larger than 10,the code can't be available,how can i get the value.
I am trying to call procedure from PRO C Procedure has many parameters and I do not need to put all of them when I call procedure. Is there way to make the same way as in PL/SQL
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.
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?
I am inserting empno in a table1 and updating another table2 using table1 empno and getting ora-01427 error. I want to print empno for whis this error is coming. How to print that value?
how to integrate SQLnet & c and I'm quite losted at the moment.
Searching with google gives some random stuff, which does seems to be irrelevant.some oracle db somewhere and need for good way to use that remote db (one solution seems to be using SQLnet).
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; [code]...
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)
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 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.
