JDBC/OCI8 Array inserts

Does JDBC/OCI8 support array inserts? I'm familiar with the C/C++ array inserts, but I haven't found anything on array inserting using JDBC/OCI8.
Array processing gives an application a real performance boost and I was hoping to use it in Java.

Hi ,
I am facing the same problem with
Oracle 8.1.5 on Windows NT.
Driver : 8.1.6 JDBC OCI Driver
JDK 1.2.2
Any workaround / patch to solve this problem please ?
Thanks,

Array Insert/Update/Select in JDBC

I've been using array processing in ODBC, OCI, and Pro*C for years and desperately need to do so in JDBC. I've thus far been unsuccessful and am beginning to doubt that it's supported which to me is unfathomable. I've likewise found many like inquiries on the net - none of which were addressed. There have been many respondants who don't undertstand what array processing is and mistake it for batch SQL statements. They are not the same. Batched SQL statements are seperate statements which are executed in a single call to the database engine. What I'm taking about is using a prepared statement and binding primitive arrays to the statement. A single statement is executed and the contents of the arrays passed to the database. I've conducted tests years ago and array insert/update is many times faster than batch statements. Does anyone know whether or not JDBC supports array processing? If anyone's interested, I can provide snippets via email which illustrate how this is done in ODBC and other API's.
Thanks.

You referred me to
http://java.sun.com/products/jdbc/download.html. The
only reference I found to arrays were SQL Arrays - not
what I'm talking about. See prior C/ODBC snippet. Do
you know how to do this in JDBC?You are talking about passing an array as a single parameter to and from the underlying database correct? (And that has nothing to do with batch processing.)
If so in section 16.4 "Array Object"..... looking at that section gives the following reference....
The Array object returned to an application by the ResultSet.getArray and
CallableStatement.getArray methods is a logical pointer to the SQL ARRAY
value in the database; it does not contain the contents of the SQL ARRAY value.
The above has nothing to do with batch processing (although presumably one could use it in a batch process but then one can use String as well.)
Of course perhaps there is something in there that says that only applies to batch processing. If so could you please point out the section and quote the text.

JDBC를 이용해서 BLOB COLUMN 에 파일 INSERT하는 SAMPLE

JDBC를 이용해서 BLOB COLUMN 에 파일 INSERT하는 SAMPLE
====================================================
Purpose
JDBC를 이용해서 BLOB COLUMN 에 파일 INSERT하는 방법을
알아 봅니다.
Explanation
- 다음 sample은 Oracle DB v8.1.7에서 JDBC(V8.1.7)을
이용해서 TEST한 것입니다.
Example
import java.sql.*;
import java.io.*;
import java.util.*;
import oracle.jdbc.driver.*;
//needed for new CLOB and BLOB classes
import oracle.sql.*;
public class Insert_File_BLOB
public static void main (String args [])
throws Exception
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@krint-7", "scott", "tiger");
conn.setAutoCommit (false);
Statement stmt = conn.createStatement ();
// Drop the basic_lob_table
try
stmt.execute ("drop table basic_lob_table");
catch (SQLException e)
// An exception could be raised here if the table did not exist already
// but we gleefully ignore it
// Create a table containing a BLOB and a CLOB
stmt.execute ("create table basic_lob_table (x varchar2 (30), b blob, c clob)");
// Populate the table
stmt.execute ("insert into basic_lob_table values ('one',empty_blob(), 'clob column data !!!')");
// Select the lobs
OracleResultSet rset = (OracleResultSet)stmt.executeQuery("select b from basic_lob_table where x='one' for update");
while (rset.next ())
// Get the lobs
BLOB blob = ((OracleResultSet)rset).getBLOB (1);
try
File file = new File("c:\\temp\\bokim.txt");
long fileLength = (long) file.length();
System.out.println("File Size : " + fileLength + " bytes");
FileInputStream instream = new FileInputStream(file);
OutputStream outstream = blob.getBinaryOutputStream();
int size = blob.getBufferSize();
System.out.println("BufferSize: " + size + " bytes (#)\n");
byte[] buffer = new byte[size];
int length = -1;
while ((length = instream.read(buffer)) != -1)
outstream.write(buffer, 0, length);
System.out.print("#");
System.out.println();
instream.close();
outstream.close();
System.out.println("\nUpdate Done.");
catch (java.io.FileNotFoundException fe) {
System.err.println ("thrown: java.io.FileNotFoundException\n");
fe.printStackTrace ();
System.err.println (fe.getMessage ());
stmt.close();
conn.commit();
conn.close();
결과

Array Inserts with Java?

Hey,
Just doing some forward thinking for a project and ran into a
question that I can't seem to find a straight forward answer to.
I'll be importing data from a flat file structure and want to
make it as fast as possible to process as it may be a large set
of records.
Can Java (JDev 2.0) do array inserts. I'd like to achieve
something like PRO*C in that I want to be able to pass an array
of records to insert, batching them so that it's not a single
network (or database) hit per record inserted.
Any help appriciated!
Doug

Doug,
I think any kind of mass inserting is not going to be optimal
over JDBC.
I am pretty sure the batch update just saves you some network
roundtrips. I believe each insert/update would still be a
separate transaction once on the server side, if nothing else for
the purposes of rollbacks, etc.

The ABAP/4 Open SQL array insert results in duplicate database records

Hi,
Iam getting following error :
The ABAP/4 Open SQL array insert results in duplicate database records.
Error in ABAP application program.
The current ABAP program "SAPLV60U" had to be terminated because one of the

This is probably due to an error in the ABAP program.
" Information on where terminated
The termination occurred in the ABAP program "SAPLV60U" in "VBUK_BEARBEITEN".

ABAP/4 Open SQL array insert results in duplicate databaserecordsfor pk13

Hi Experts, when I am working with pk13n tranaction iam getting an error message stating that update was terminated by user. when i am checking with st22 it gives the following message. please give the solution , iam sending the code as well.
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_OPEN_SQL_DB', was not caught
in
procedure "SAVE_DATA" "(FORM)", nor was it propagated by a RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
If you use an ABAP/4 Open SQL array insert to insert a record in
the database and that record already exists with the same key,
this results in a termination.
(With an ABAP/4 Open SQL single record insert in the same error
situation, processing does not terminate, but SY-SUBRC is set to 4.) please find the below code please give the solution for this error message.

Hi,
Well I don't know why you have duplicates, this is a functionnal issue. But you get the dump due the the message number 864 that triggers the abend... Changing the message type to 'E', 'S' or 'I' will prevent the dump but I guess this message has a good reason to be

The size limit of the OCI LOB Array Insert is 64K for one field?

I have a table with 4 field, and one is BLOB field. I want to insert 16 rows in one OCIStmtExecute. I know I can specify the iter parameter with 16 to execute sql 16 times.
I found example in "Application Developer's Guide - Large Objects" in page "Data Interface for Persistent LOBs 13-17", there is a example function called "array_insert". It shows the usage of OCIBindArrayOfStruct, but can only insert LOB with same size, the LOB field of each row filled with the same size data.
But I have to insert LOB with different size, for example 8K for row 1, and 16K for row 2, 128K for row 3. Than I find the alenp parameter of OCIBindByName/OCIBindByPos. It is "pointer to array of actual lengths of array elements."(OCI document). So I think I find the solution for my problem. But the type of alenp parameter is ub2*, is it means I can only insert 64K data for each row in my array insert? It is too small, I hope I can array insert BLOB with 16M each row.
Or there is any other solution for my problem? I look forward to it for a long time! thanks every one!

It is called Data Interface to work with LOB datatypes by APIs designed for use with legacy datatypes. I can specify SQLT_BIN to bind memory binary data to BLOB column, and INSERT or UPDATE directly. It can be without LOB locator and save round-trip to the server. This is very fit my needs, because I have to insert very much BLOBs to server as soon as possible.
I have make a test program, and multi-row with different size blob( less than 65536 bytes) can be insert at one time, without locators. Multi-row wiht same size blob( more than 64K) also can be insert at one time--the alenp parameter is not used. I only can not insert multi-row with different size blob( more than 64k) because the type of alenp is ub2*.
thank you for your reply!

The ABAP/4 Open SQL array insert results in duplicate Record in database

Hi All,
I am trying to transfer 4 plants from R/3 to APO. The IM contains only these 4 plants. However a queue gets generated in APO saying 'The ABAP/4 Open SQL array insert results in duplicate record in database'. I checked for table /SAPAPO/LOC, /SAPAPO/LOCMAP & /SAPAPO/LOCT for duplicate entry but the entry is not found.
Can anybody guide me how to resolve this issue?
Thanks in advance
Sandeep Patil

Hi Sandeep,
Now try to delete ur location before activating the IM again.
Use the program /SAPAPO/DELETE_LOCATIONS to delete locations.
Note :
1. Set the deletion flag (in /SAPAPO/LOC : Location -> Deletion Flag)
2. Remove all the dependencies (like transportation lane, Model ........ )
Check now and let me know.
Regards,
Siva.

Madhu,
Do the following:
1. create prepare statement
e.g
stmHnd : DBStatementHandle;
inputData : DBDataset = new;
stmType : integer;
stmHnd = DBSesObj.prepare('insert into
table_name myCOl1, myCol2, myCol3
values(:myCol1Value, :myCol2Value, :myCol3Value)',
inputData,stmType);
2. Populate the input DBDataset.
e.g
// assign the maximum value
inputData = myArrObj.items;
// assign the values
for i in 1 to myArrObj.items do
inputdata.currentRow = i;
inputdata.setvalue(':myCol1Value',
myArrObj.attr1);
inputdata.setvalue(':myCol2Value',
myArrObj[i].attr2);
inputdata.setvalue(':myCol3Value',
myArrObj[i].attr3);
end for;
3. execute the statement:
e.g .
DBSesObj.execute(stmHnd, inputData);
4. release the handle
DBSesObj.RemoveStatement(stmHnd);
Hope this helps,

Amos,
Why don't you use, Dyanmic SQL statement,
where
you need to prepare only one SQL Statement, and
populate input place holder, which is much simpler
and
you need to access the database only one time(which
is
efficient operation). This is useful, especially,
when
you want to update. But for your inforamtion, Forte
internally inserts, one by one row, even if u call
Static SQl statement, with array of record. Os its
advisable to use Dyanmic SQL statement.
Hope this helps,

Hi,
There must be inconsistency in the number range. This happens when the current number in the number range for dependent requirements is lower than the highest number in the database table of the dependent requirements RESB.
Please check the current number in transaction OMI2. Here in the interval you can see the current number. Then please check the highest number in table RESB. If the current number in OMI2 is lower than the highest number in table RESB then this should be the reason for the dump.
Check and revert. If that's not the case we'll look into other possibilities.
In mean time check for SAP Note 138108.

ABAP/4 Open SQL array insert results in duplicate database records in SM58

Hi Everyone,
I am testing a file to idoc scenario in my Quality system. When I passed the input file, the mapping executed successfully and there are no entries in SMQ2 but still the idoc wasn't created in the ECC system. When I have checked in TRFC, I am getting the error ABAP/4 Open SQL array insert results in duplicate database records for IDOC_INBOUND_AYNCHRONOUS function module. I thought this is a data issue and I have tested with a fresh data which was never used for testing in Quality but even then I am getting the same error.Kindly advise.
Thanks,
Laawanya

use FM idoc_status_write_to_database to change the IDoc status from 03 to 30 and then run WE14 or RSEOUT00 to change the status back to 03
resending idoc from status 03 ...is a data duplicatino issue on receiving side...why do u need to do that ?
Use WE19 tcode to debug
In we19
1)U can choose your Idoc number in existing Idoc textbox
2)Press execute
3)u will display ur Idoc struct
4)Dbl click on any field then u can modify its content
5)PressStd Outbound Processing Btn to process modified Idoc
Thats it
