New to OCI

hello,
I am new to OCI.
Could I use OCI to interface a C application with Oracle Database 10g?
If possible, how to do it?
What other stuffs do I need? like any drivers needed?
Thanks in advance.
Regards.

If you're not familiar with C programming, and not familiar with OCI, what lead you to choose that as your API? Can you describe your application requirements and what languages & API's you're familiar with?
Unless you're developing a trivial application, a couple of months strikes me as rather ambitious if you're trying to learn C and OCI along the way. If you have questions, you can certainly post them in this forum-- I'm not aware of any resources better than this forum and the OCI documentation for dealing with OCI. There are a number of sample OCI applications that ship with the Oracle client (the companion CD in 10g)-- studying those should help.

Which OCI library to use for static linking with application on Unix, Linux

Hi Friends
I am new to OCI programming.
I am developing a C++ application that works on Windows 7 (32, 64 bit, VS-9) and Linux (32, 64 bit), with OCI-11.2.0.3 version and Oracle 10g Express edition.
I want to statically link OCI library in my application.
For Windows, I got oci.lib in the package: instantclient-sdk-nt-11.2.0.3.0.zip\instantclient_11_2\sdk\lib\msvc downloaded from [Instantclient download location.|http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html] .
But, the instanclient packages instantclient-basic-linux-11.2.0.3.0.zip & instantclient-sdk-linux-11.2.0.3.0.zip do not contain a static archive for OCI library.
These packages have only include files and following .so (shared libraries) for Linux:
libclntsh.so.11.1
libnnz11.so
libocci.so.11.1
libociei.so
libocijdbc11.so
Can someone please guide me, where can I find the static archive (possibly liboci.a or libociei.a) for OCI-11.2.0.3 - 32 & 64 bit?
Many thanks in advance for your time and kind guidance.
Best Regards,
-ganes

You need:
libclient11.a
libcore11.a
libgeneric11.a
libcommon11.a
libn11.a
libldapclnt11.a
libncrypt11.a
and others.
Actually, you can link to all *.a files in $ORACLE_HOME/lib
EXCEPT: libclntst11.a and libexpat.a

The above program works on my Windows desktop. If I try this in Solaris, OCILogon fails and gives an error. If I check the value of rc, I find that it is -2. I can connect to the database using SQLPlus, but not through the program. Not sure how to debug this...
Any pointers ?
Thanks in advance,

Did you make the required port entry in the /etc/services file? You will need to add the gateway service port there. Then try to run your program.

How to represent Nested table as variable/Object in OCI

Hi All,
I'm new to OCI.
I've following nested table in my database.
Nested table:
create type type1 as object (name varchar2(20));
create type type2 as table of type1;
create table table1 (col1 varchar2(20), col2 type2) nested table col2 store as table2;
Can anyone help me to present col2 as C structure/typedef so as to use it with OCIDefineObject?

You can have a look at Chapter 11 of the OCI Programmer's Guide. Look at the section Collections in it. You can represent the nested table as OCITable *. Further, you can generate structure representation of your object type by using OTT. Please let us know if this answers your question. In case you are not able to proceed please let us know.
Thanks,
Sumit

New PDO drivers in PHP 5.1 leave much to be desired.

I used ADOdb for more then 2 years and was extremely satisfied with it, but decided to test-drive the new, unified, database interface. Here is a little script that I created:
#!/usr/local/bin/php
<?php
$SQL1="select * from emp where ename like :ENAME";
$name='%';
try { $dbh = new PDO("oci:dbname=local", "scott", "tiger");
$sth=$dbh->prepare($SQL1);
$sth->bindParam(":ENAME",$name,PDO_PARAM_STR,100);
$sth->execute();
$cnt=$sth->columnCount();
echo "This statement returns ",$cnt, " columns\n";
for($i=0;$i<$cnt;$i++) {
print_r($sth->getColumnMeta($i));
print("\n");
catch (PDOException $e) {
echo "Failed to obtain database handle " . $e->getMessage(),"<br>\n";
?>
Here is the output:
$ ./test_pdo.php
This statement returns 8 columns
PHP Warning: PDOStatement::getColumnMeta(): SQLSTATE[IM001]: Driver does not support this function: driver doesn't support meta data in /home/mgogala/tmp/test_pdo.php on line 13
PHP Warning: PDOStatement::getColumnMeta(): SQLSTATE[IM001]: Driver does not support this function: driver doesn't support meta data in /home/mgogala/tmp/test_pdo.php on line 13
PHP Warning: PDOStatement::getColumnMeta(): SQLSTATE[IM001]: Driver does not support this function: driver doesn't support meta data in /home/mgogala/tmp/test_pdo.php on line 13
The query executes correctly, because I am getting the correct number of columns. Unfortunately,
the driver tells me that it cannot describe the column, that is, return array containing name,
native data type, length, precision and PDO data type. That is ridiculous as all 3 other methods
(OCI8, PEAR DB and ADOdb) have no problems whatsoever with describing the column. OCI8, the most comprehensive one of those packages has the following functions to that end:
ocicolumnname -- Returns the name of a column
ocicolumnprecision -- Tell the precision of a column
ocicolumnscale -- Tell the scale of a column
ocicolumnsize -- Return result column size
ocicolumntype -- Returns the data type of a column
Using those functions, I would have no problem obtaining the desired information. PDO_OCI
can't do that. So far, it is very far away from being actually usable. Things might look better
when 5.1 is actually released, but so far it can't be used. Also, when an incorrect SQL is used
in the script above, an exception is not thrown.
I commend your efforts to promote it and I believe that Zend Core for Oracle is a great thing as
it simplifies the installation a great deal, but I will continue to use ADOdb for the foreseeable future.

Hmmm, the script in my post is all squashed and ruined, despite my best efforts.
If you need original, please contact me at [email protected] There is also an intial version
of a DBA tool written in PHP5 on my web page, which is: http://www.mgogala.com

How do I execute "Select count(*) from table " in OCI

Hi,
I am new to OCI and so this question may seem stupid. I would like to know how to execute the query "select count(*) from <table>" using OCI V8 functionality? Also after how do I get the result into a integer datatype? I have gone through most of the demo programs but is is of little help to me.
Thanks in advance...
Regards,
Shubhayan.

Hi,
Here is sample code to give you some idea how to do it. If you want some more info let me know.
Pankaj
ub4 count;
// Prepare the statement.
char szQry = "SELECT count() FROM T1";
if(OCI_ERROR == OCIStmtPrepare(pStmthp, pErrhp, (unsigned char*)szQry, strlen(szQry), OCI_NTV_SYNTAX , OCI_DEFAULT) )
     cout << "Error in OCIStmtPrepare" << endl;
     exit(1);
// Bind the output parameter.
OCIDefine *pDefnpp;
if(OCI_ERROR == OCIDefineByPos ( pStmthp, &pDefnpp, pErrhp, 1,
&count, sizeof(ub4), SQLT_INT,
(dvoid *) 0, (ub2 *) 0, (ub2 *) 0,
                    OCI_DEFAULT) )
     cout << "Error in OCIDefineByPos" << endl;
     exit(1);
if(OCI_ERROR == OCIStmtExecute(pSvchp, pStmthp, pErrhp, 1, 0, NULL, NULL, OCI_DEFAULT) )
     cout << "Error in OCIStmtExecute" << endl;
     exit(1);

Creating Rule file to pull data from OCI Interface

Hi.
I am new to OCI, I have worked on DSN method earlier to pull data from database.
Can someone give me steps of how to pull data from OCI interface.
My database is Oracle 11gR2 and I am using 11.1.2.2 Fusion version.
Regards
Mahesh Balla

The following post may help - Re: Essbase Rules Files and OCI
There have been a number of issues relating to data and using OCI, I am not sure whether they are all resolved in 11.1.2.2 so if you are using OCI make sure you validate the data once loaded into essbase.
Cheers

"new PDO" inconsistent in connections across our servers

Using PDO oci, our application web pages connect to various Oracle databases. All database connections before used the following connect strings successfully:
$conn = new PDO("oci:dbname=//servername.domain*:1521*/db_service_name",$db_username,$db_password);
up until last Friday 5/18 when one particular server connection attempt would throw a "Fatal error" unless we modify the connection string as follows:
$conn = new PDO("oci:dbname=//servername.domain/db_service_name",$db_username,$db_password); // no port number
php version appears to be 5.3, database version is 10.2.0.5.0, all running on linux RHEL 5. Other connections using RHEL 4, but I believe that is moot in that the app server running php 5.3 with oci8.so to connect to the database server running oracle 10.2.0.5 was working, but on Monday 5/21, it was not working.
Fatal error when not working is:
PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[]: (null)' in /home/driskind/test_oci.php:7
Stack trace:
#0 /home/driskind/test_oci.php(7): PDO->__construct('oci:dbname=//ea...', 'user...', 'password')
#1 {main}
thrown in /home/driskind/test_oci.php on line 7
Note that from this same host, php can connect to older database servers utilizing the connection string with the port number, so I am suspecting a configuration on the database server side for the new database server where connection string using port number fails.
Please don't ask why application doesn't use other methods. They have adamantly stated they wish to continue to use thier application with php configured as is.

Unless things have really changed with PDO I recommend not using it. Just use the OCI_ methods. For me the biggest problem is that PDO ( at my last reading ) does not support reference cursors which for me is just a non starter.

Wls1211_generic.jar & wls_121200.jar & OCI

DriverManager.getConnection("jdbc:oracle:oci:@", info); work prefect on weblogic installed from(wls1211_generic.jar)!
But when i try run it under weblogic installed from wls_121200.jar it throw "java.lang.UnsatisfiedLinkError: no ocijdbc11 in java.library.path"
System.getProperty("java.library.path");
wls_121200.jar
wls1211_generic.jar
D:\app\product\112~1.0\client_1\BINBIN;
D:\app\product\11.2.0\client_1\BIN;
when I start weblogic(wls_121200.jar) with "-Djava.library.path=D:\app\product\11.2.0\client_1\BIN;" it throw "java.lang.UnsatisfiedLinkError ocijdbc11.dll: Can't find dependent libraries"
How to resolve this problem?
P.S. I am sorry for my english.

You can make your life much simpler and lose nothing if you were to use the JDBC driver in the 'thin' mode, not 'oci'.
The oci mode is not recommended for several reasons:
1 - There is a brittle one-to-one relationship between a given version of the JDBC driver jar, with a given version of
the Oracle OCI client libraries, so if you change the driver version (WLS versions have different driver versions),
then you would have to install the new/appropriate OCI libraries.
2 - Any bug in OCI native code can kill an entire JVM/weblogic server.
There is nothing nowadays that the driver operating in the thin mode cannot do, that it can do in the OCI mode,
and using it that way allows you to run or change among any multiple versions of the driver without concern,
as they run independently and are completely self-contained.

Creating OCI Arrays

I am creating Oracle 9i Spatial objects, which have two VARRAYs. I am new to OCI. What is the usual way of creating with varrays in OCI? I can get the object created with OCIObjectNew, and append elements one at a time with OCICollAppend, but I am a little unhapy with this - I expected to be able to allocate storage for a number of elements, then set them one at a time. I distrust the overhead and fragmentation of memory using an append for each element.
The OCI Guide provides no examples, and I can only find one example program writing a collection.
Is there a way of allocating multiple entries for the varray at once ?
Are there other examples of writing varrays or other collections?
Thanks,
David Penington

Nope. Once you create an array, and give it a size, you're stuck with it. Its the same in any language that I've used (C, Pascal, Java...)
If you need a larger array(ie add one more element in) you need to redeclare your array.
There is a helper method that you can use:
System.arrayCopy(...) will copy the values from one array to another for you.
public String[] addName(String[] names, String newName){
String[] newList = new String[names.length+1]);
for (int i=0; i<names.length; i++){
newList[i] = names;
newList[newList.length-1] = newName;
return newList;
// somewhere in another method...
public void testArray(){
String[] names = new String[0];
names = addName(names, "Bob");
names = addName(names, "Bill");
No its not wonderfully efficient, but thats how its done.
The availability of the Collections framework for dynamically sized lists means that not being able to do it with primitive arrays isn't so important.

How to call store procedure from an oci program

Hello,
I work on Oracle 8.1.7 under AIX.
I must call from an OCI C++ program a store procedure that have an result set as param out.
I'm not sure how can I call the procedure/function. I want to execute this statement and fetch the results.:
" CALL Department.get_all (:1) " is this OK?
" Call department.GetAll() into :1 "
I have seen some example from an PL/SQL block but that's not ok for me.
what i have done:
i have created an package
create or replace package department as
type cursor_type is ref cursor;
procedure get_emp( i_deptno in number, rs out cursor_type );
procedure get_all( rs out cursor_type );
function GetAll return cursor_type;
end department;
create or replace package body department as
procedure get_emp ( i_deptno in number, rs out cursor_type )
as
begin
open rs for
select empno, ename
from emp
where deptno = i_deptno;
end;
procedure get_all ( rs out cursor_type )
as
begin
open rs for
select empno, ename
from emp;
end;
function GetAll return cursor_type
as
l_cursor cursor_type;
begin
open l_cursor for select ename, empno from emp;
return l_cursor;
end;
end;

Hi,
I am new to OCI facing the same problem you have mentioned, If you have found out how to solve it , can you post the answer for the same.

Fetching whole table using OCI calls

I am new to OCI programming .I am writing an appliaction in C# to fetch data from ORACLE using OCI calls,Using that application i can able to fecth single row,
but i need to load/ fetch the entire table data from the database using the single fetch?
I have created a scrollable resultset by using the below give statement
and i can able to fetch single coloumn.
short paramSizee = 20;
IntPtr TestNo = GetPointer((int)paramSizee);
rc = OCI.OCIDefineByPos(hStatement, out HDefine, hError, 1, TestNo, paramSizee, OCI.DATATYPE.VARCHAR2, OCI.NullHandleRef, OCI.NullHandleRef, OCI.NullHandleRef, OCI.MODE.OCI_DEFAULT);
if (rc != 0)
Console.WriteLine(CheckError(hError));
throw new Exception("OCI Define Failed...");
rc = OCI.OCIStmtExecute(hServiceContext, hStatement, hError, iters, 0, OCI.NullHandleRef, OCI.NullHandleRef, OCI.MODE.OCI_STMT_SCROLLABLE_READONLY);
rc = OCI.OCIStmtFetch(hStatement, hError,50, OCI.FETCH.OCI_FETCH_NEXT, OCI.MODE.OCI_DEFAULT);
if (rc != 0)
Console.WriteLine(CheckError(hError));
throw new Exception("OCI Fetch Failed...");
Using above calls i can able to fetch arround 100 rows per fetch but my customer table has 16000 rows .
So it will be great if someone suggest proper way to fetch entire table data in single fetch.
Thanks,
Raj

For fetching large number of rows in single Db roundtrip use the following
To get the bulk Data use the following.MAX_PREFETCH_ROWS is the integer value you want fetch in BULK
(void) OCIAttrSet((dvoid *)DBctx->stmthp, (ub4) OCI_HTYPE_STMT,
(dvoid *)&MAX_PREFETCH_ROWS,(ub4)sizeof(MAX_PREFETCH_ROWS),
(ub4) OCI_ATTR_PREFETCH_ROWS, DBctx->errhp);

Usage of Varray in a Stored Procedure Executed through OCIStmtExecute

Hi,
I'm new to OCI Programming. My requirement is to pass an array to a Stored Procedure.
In Stored Procedure this input variable is of type VARRAY.
I'm following the approach given below.
OCITypeByName()
OCIObjectNew()
OCICollAppend()
OCIBindByPos()
OCIBindByObject()
OCIStmtExecute()
I encounter an error in OCITypeByName (this function call fails)
Can anyone provide me some sample codes
Also pls provide information if there is a better approach to be followed in this regard.
Thanks,

Hi Alamelu,
Make sure you created the type correctly in the database using SQL DDL.
You can verify that from sqlplus
sqlplus username/password
describe typename;
Here is a code snippet :-
#define SCHEMA "TKP8ADT1"
OCITypeByName(envhpx, errhp, svchpx, (const text *) SCHEMA,
(ub4) strlen((char *)SCHEMA), (const text *) "ADDRESS_VALUE",
(ub4) strlen((char *)"ADDRESS_VALUE"), (CONST text *) 0,
(ub4) 0, OCI_DURATION_SESSION, OCI_TYPEGET_HEADER, &addr_tdo);
thanks,
Ravi
