Inserting into Postgres via ODBC Gateway

Hi, I've made some tests, here are results and questions:
Postgres:
CREATE TABLE t_dump
str character varying(100)
)Oracle: [ORADB: db link to Postgrers]
INSERT INTO "t_dump"@ORADB VALUES ('test'); Works fine, both from SQL as from PL/SQL
However:
Declare
m_str Varchar2 (10) := 'test';
Begin
INSERT INTO "t_dump"@ORADB VALUES (m_str);
End;Gives me an error:
Error report:
ORA-00604: error occurred at recursive SQL level 1
ORA-02067: transaction or savepoint rollback required
ORA-28511: lost RPC connection to heterogeneous remote agent using SID=ORA-28511: lost RPC connection to heterogeneous remote agent using SID=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=DB)(PORT=1521))(CONNECT_DATA=(SID=pg)))
ORA-02055: distributed update operation failed; rollback required
ORA-02063: preceding lines from ORADB
ORA-06512: at line 8
00604. 00000 - "error occurred at recursive SQL level %s"
*Cause:    An error occurred while processing a recursive SQL statement
           (a statement applying to internal dictionary tables).
*Action:   If the situation described in the next error on the stack
           can be corrected, do so; otherwise contact Oracle Support.Dynamic SQL gives exact same error:
Declare
m_str Varchar2 (10) := 'test';
Begin
EXECUTE IMMEDIATE
'INSERT INTO "t_dump"@ORADB VALUES (:v0)'
Using m_str;
End;Is there any way I could use variables into queries?
One more issiue:
I have created partitioned table in Postgres, and simple INSERT statement works fine [SQL from Oracle]; however- the same statement, enclosed with begin/end [PL/SQL] needs about 60 seconds to finish. Is it normal behaviour? Is there any config/pragma/.. I could use to speed it up?

Hi,
Your sample also doesn't work in PL/SQL block..
Here is my detailed config:
Oracle Database 11g Release 11.2.0.1.0 - 64bit Production
TNS for Linux: Version 11.2.0.1.0 - Production
PostgreSQL 8.4.8 on x86_64-pc-linux-gnu, compiled by GCC gcc-4.5.real (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2, 64-bit
and latest ODBC version from Postgres webpage (09.00.0310)
I will install the latest Postgres DB and try it then
Here is the trace, with removed some 'libname=/usr/lib64/libodbc.so, funcname=SQLGetDescRec' parts from init

ORA-06502: error when inserting into table via db link with long datatype

Folks,
I am getting the following error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small.
This occurs when an insert is done via a database link into a table that has a LONG data type for one of the columns, and the string contains some carriage returns and or line feeds.
I have checked by removing the db link, and inserting into a local table with identical column data types, where there is no error.
So this might be another db link bug?
So I need to remove the carriage returns and/or line feeds
in my pl/sql block in the page process. I have tried
l_text := REPLACE(l_text, CHR(10), ' ');
l_text := REPLACE(l_text, CHR(13), NULL);
but still getting the ORA-06502. Would really appreciate some advice here, please.
Cheers
KIM

Scott,
Time to 'fess up':
My fault sorry, the error was coming from another page process where I had allowed insufficient string length for one of the variables, and my error message did not identify the page process clearly.
This leads me to make a request for future releases, could the system error messages state which page process caused the problem?
One other thing I notice, and this might be a feature not a fault, the page processes are numbered: "Page Process: 3 of 5". However process 3 is not the 3rd one to be processed, and probably refers to the order in which they are created. Should the number reflect the process order?
Cheers

Issue inserting into USER_SDO_GEOM_METADATA via Oracle Apex

G'day All,
I've originally riased my issue in "Application Express - http://forums.oracle.com/forums/thread.jspa?threadID=537922&tstart=45 " but have not had any solutions provided yet.
Just a quick summary, when I insert a record into user_sdo_geom_metadata using Oracle Apex SQL Command tool and run a select on the view no records appear. After a bit of investigating I found it is wrongly being given a SDO_OWNER value of ANONYMOUS instead of the value from sys_context('userenv', 'CURRENT_SCHEMA') which in my case would be "TEST".
When I run SELECT sys_context('userenv', 'CURRENT_SCHEMA') FROM DUAL it correctly returns "TEST".
If anyone could let me know whats going wrong I would be most appreciated :)
Cheers
Mark

try to
grant select on table1 to schema2....
Once you have granted the access to teh schema...you should be able to access the MDSYS schema.
This should be OK.

Strange data inserted into table via table trigger

Hi ,
There is some strange phenomenon happen occasionally where some tables update records will have a TRIGGER to insert records into a table and once in a while, the record has some strange data inserted which looks like a memory corruption. It is running on 10.2.0.3.
Does anyone ever encounter this before?
Strange result:
PRIM_KEY
-3.614364951000000000000000000000000E-47
-3.614364951000000000000000000000000E-47
Normal result:
PRIM_KEY
1137KT
1137KT

Hi,
What is strange in this? Its not memory corruption. Its just one of the numeric form of representation of number
-3.614364951000000000000000000000000E-47it means -3.614364951 * 10 to the power of -47.
Whatever value has been entered into the table depends on your business logic you coded, and user input.

File to RFC problem- data is not inserting into ztable in R3 system

Hi
i have done File to RFC scenario which picks data from flat file and inserts into ztable via RFC in R3. but while testing my scenario everything is successful in XI monitoring (Successful flag in MONI and RWB) and in auditlog message status is DLVD.
it seems to be everything successful in XI and RFC call also successful in R3 system.
but for some reason data is not inserting into table (RFC is used to insert data into ztable)
Is there any way to debug RFC call excecution in XI..?
RFC code is like this:
insert ZMM_AUTO_GR from INPUT_TABLE.
commit work.
END FUNCTION.
please advice what could be the reason not inserting into table.
Help would be appreciated.

ORA-22275 inserting into the CLOB column using ODBC input parameters

Hi all,
I'm having problem with INSERT into the CLOB column via bound input parameters.
After calling SQLExecDirect() I'm getting following error:
[Oracle][ODBC][Ora]ORA-22275: invalid LOB locator specified
Adding defaults to the table definitions does not help. If I embed parameter values into the SQL statement - everything works just fine.
I use Oracle 9.2 with latest Oracle ODBC driver 9.2.0.4 under Windows XP.
Any ideas appreciated...
Vlad
Code looks like this:
SQLBindParameter(hstmt,1,...);
SQLBindParameter(hstmt,2,...);
SQLBindParameter(hstmt,3,...);
SQLExecDirect(hstmt,...);
SQL statement looks like this:
insert into tst_table (id,str_fld,clob_fld1,clob_fld2) values (50, ? , ? , ?)
Table looks like this:
CREATE TABLE tst_table (
     id          number (10,0)     NOT NULL ,
     str_fld          nvarchar2 (50)     NOT NULL ,
     clob_fld1     nclob          NOT NULL ,
     clob_fld2     nclob          NOT NULL ,
     CONSTRAINT PK_tst_table PRIMARY KEY
          id
I tried to add defaults to the table, but result is the same:
CREATE TABLE tst_table (
     id          number (10,0)               NOT NULL ,
     str_fld          nvarchar2 (50)               NOT NULL ,
     clob_fld1     nclob     default EMPTY_CLOB()     NOT NULL ,
     clob_fld2     nclob     default EMPTY_CLOB()     NOT NULL ,
     CONSTRAINT PK_tst_table PRIMARY KEY
          id

You need to provide the data at execution time (i.e. SQL_LEN_DATA_AT_EXEC(0) in the SQLBindParameter followed by a series of SQLPutData calls). If you go to Metalink
Top Tech Docs | Oracle ODBC Driver | Scripts & Sample Code
has some sample code that shows you how to do this.

Update/Insert mode couldn't apply to SQL Server source via Transparent Gateway.

Hi all,
OWB version is 9.0.2.56,database version is 9i Release 2.
When set load type to "Insert",mapping works fine from SQL Server to Oracle table,via Transparent Gateway 901.
But "Update/Insert" always runs error with "Fatal error or maximum number of errors exceeded".while I define both source and destination table to oracle tables in mapping,"Update/Insert" works file.
Any suggestion?

Hi Ignor,
Thanks for your reply!
The SQL Server version is SQL Server 2000.
I just want to ETL data from a SQL Server table via Transparent gateway into oracle table,the source table has a increment seq field,so I want to define mapping using update/insert loading method in OWB,according to this seq field,if there is the same seq in the target table,do update,if not,insert the row.I just find out that if I use a middle table in oracle to do truncate/insert mode from SQL Server source table,then do update/insert mode from the middle one to target table,it works.But can't do directly from source to target using update/insert mode.Does this means update/insert mode only apply to mapping from local table to local table?

Hi,
Since 9.2 has been desupported for error correction you will not be able to download that version from OTN. You should ask whoever is providing the training if their is an alternate version you can use. The only versions that you will be able to download from oracle.com is 10.2 11.1, and 11.2.

Insert byte[] into postgres text-field

Hi,
i made some tries on using postgresql and jdbc, i noticed that
for some reason the postgres jdbc.driver does not convert
text from the db correct to UNICODE. The db is in ISO-8859-1.
So, i tried to write a workaround to this and was successfull
for reading data. The code is this:
try {
    String sOrt   = null;
    InputStreamReader isString;
    BufferedReader bisString;
    ResultSet result =
        stmt.executeQuery( "select * from adresse.ort" );
    while( result.next() ) {
        isString = new InputStreamReader(
                            result.getBinaryStream( "ort" ),
                            "ISO-8859-1" );
        bisString = new BufferedReader( isString );
        sOrt = bisString.readLine();
...This works fine. Now i also wanted to but a correctly convertet
String in the db.
And i tried so:
try {
    String sOrt = "solal�";    // note the special german char �
    byte[] sOrt_ba = sOrt.getBytes( "ISO-8859-1" );
    pstmt = con.prepareStatement( "insert into adresse.ort " +
                                  "(ort, vorwahl_o, id_land) " +
                                  " values " +
                                  "(?, '00000', 1)" );
    pstmt.setBytes( 1, sOrt_ba );
    int sRows;
    sRows = pstmt.executeUpdate();
}but this sets not the correct character for the special char �
but instead puts the byte-value \366 into the db.
My question is as simple as the answer might be complex, what am
i doing wrong, and how can i accomplish this.

i found a solution for me, its not clean (to be sure its very ugly) but it works for the moment, if anyone has a better idea please tell. I will make the
following.
create a small plpgsql function like this.
CREATE FUNCTION jdbc_clean(text) RETURNS text AS'
    DECLARE
        ret text;
    BEGIN
        SELECT INTO ret replace($1, ''\\\\344'', ''�'');
        SELECT INTO ret replace(ret, ''\\\\366'', ''�'');
        SELECT INTO ret replace(ret, ''\\\\374'', ''�'');
        SELECT INTO ret replace(ret, ''\\\\337'', ''�'');
        RETURN ret;
    END;
' LANGUAGE 'plpgsql'and call this in my Java-method for every String i inserted or
updated in a seperate update query.
I have not written it for now, but i guess this will be working.

Sorry genius.....but if the Recovery disk shows up that means the disk cable isn't bad. Could be he did have a screwed up HDD and when he put the NEW HDD in (after putting the OS on it via USB) the computer didn't reconize it and therefore didn't boot the OS. Just maybe right genius?

How query data in pl/sql via ODBC from DB2 on AS400

Hi,
What's the most easy way to do some selects on tables in an external (non-oracle)database via odbc?
I only need selects, no dml-statements like inserts en updates...
Where can I find more information about this subject?
Filip

You need to use Oracle Heterogeneous Services. Firstly you have to obtain and configure DB2 ODBC drivers. I got mine from ibm.com (not free) but I am sure there are some third party vendors out there. I don't know much about DB2 so I can't help you with the configuration (I asked a DB2 DBA to help me with that part).
The rest is just setting up Oracle HS and creating the DB link. The following steps should help but there are much more detailed manuals for Oracle HS on http://tahiti.oracle.com.
Listener Configuration
Add the following entry into the SID_LIST part of the listener. The SID_NAME will be used in the heterogeneous services configuration
(SID_DESC=
(SID_NAME=db2)
(ORACLE_HOME=D:\oracle\ora92)
(PROGRAM=hsodbc)
Restart the listener.
Heterogeneous Service Configuration
Under ORACLE_HOME\HS\admin create the following text file called initDB2.ora (the DB2 part should match the SID_NAME used in the listener configuration).
Put the following line in the text file (the DQ01 is the name of the DB2 ODBC System DSN):
HS_FDS_CONNECT_INFO=DQ01
Client Configuration
The client side refers to an Oracle database that will use the heterogeneous gateway.
TNSNames Entry
Put the following entry in the tnsnames.ora file (the SID part should match the SID_NAME in the listener configuration):
DB2.telkom.co.za =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=cntrra20-esdt00)(PORT=1521))
(CONNECT_DATA=(SID=db2))
(HS=OK)
Database Link
Create a database link that references the new tnsnames.ora entry:
create public database link db2
connect to oratst identified by oracle using 'db2';
Test the database link.

Problem with boolean type in Informix via ODBC

Hello,
I'm connecting to an Informix database from an Oracle database via the ODBC Gateway. The connection works fine.
However, when I select a boolean type column from a table in the Informix database, nothing is returned and I get the following error:
SQL> select "stat" from bt@informix;
ERROR:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Informix][Informix ODBC Driver]Restricted data type attribute violation.
{07006,NativeErr = -11013}
ORA-02063: preceding 2 lines from INFORMIX
no rows selected
Selecting a boolean type column with isql works fine. Other column types work from Oracle.
Can anyone help me resolve this issue? Please find configuration details and traces below.

Here are my findings after consulting the unixODBC mailing list and the IBM documentation.
There are several levels of data types at play here: native Informix SQL types, Informix ODBC driver SQL types and Informix ODBC driver C types (as well as standard C types).
According to the Informix documentation (http://www-01.ibm.com/support/knowledgecenter/SSGU8G_11.70.0/com.ibm.odbc.doc/ids_odbc_108.htm), the ODBC driver SQL type for the native boolean type is SQL_BIT.
The traces show that the ODBC SQL type is SQL_BIT (type code -7) and that this should be converted into the SQL_C_UTINYINT ODBC C type (type code -28).

Oracle tries to bind the SQL_BIT type column to a buffer of SQL_C_UTINYINT type, which requires a conversion from SQL_BIT to SQL_C_UTINYINT that is apparently not supported by the Informix ODBC Driver.
According to the documentation (http://www-01.ibm.com/support/knowledgecenter/SSGU8G_11.70.0/com.ibm.odbc.doc/ids_odbc_108.htm) the Informix ODBC driver can only convert the SQL_BIT ODBC SQL type into SQL_C_BINARY, SQL_C_BIT and SQL_C_CHAR ODBC C types. (The ODBC C types are in turn converted into standard C types, for example the SQL_C_BIT type is converted into UCHAR which is a typedef for the standard C type unsigned char.)
A possible workaround could be to tell Informix to present boolean as a different ODBC SQL type, for example SQL_CHAR (as it would be possible with PostgreSQL by setting BoolAsCharater=1 in odbc.ini), but Informix only seems to supports the SQL_BIT ODBC SQL type.
A cumbersome workaround is to use the Gateway's pass-through feature that allows a query to be passed to Informix as is, which in turn allows us to cast the boolean field into a character field:
SQL> set serveroutput on
SQL> r
1 DECLARE
2    val VARCHAR2(1);
3    c    INTEGER;
4    nr INTEGER;
5 BEGIN
6    c := DBMS_HS_PASSTHROUGH.OPEN_CURSOR@informix;
7    DBMS_HS_PASSTHROUGH.PARSE@informix(c,'select cast (stat as character) from bt');
8    LOOP
9    nr := DBMS_HS_PASSTHROUGH.FETCH_ROW@informix(c);
10    EXIT WHEN nr = 0;

12    DBMS_OUTPUT.PUT_LINE(val);

Weird exception in 12c (ORA-01461: can bind a LONG value only for insert into a LONG column)

I have a Windows app that accesses an Oracle 12c database via ODBC (the driver version is 12.01.00.01).
I have a table that has a key column named REGION_ID (NVARCHAR2(9)), and about a dozen other columns, three of which are named REGION1, REGION2, and REGION3, all of type NVARCHAR2(40).
When I try to insert a string into the REGION1 field that's greater than 9 characters (the length of REGION_ID), I get an ORA-01461 error ('Can bind a LONG value only for insert into a LONG column). If I define the length of REGION_ID to be NVARCHAR2(15), then I can add strings to the REGION1 field with a length up to 15 before I get the ORA-01461 exception again. Oddly, if I change the REGION1 column name to REGIONONE, I do not get any errors, and everything works fine. It's almost as if the column name REGION1 is being confused with REGION_ID behind the scenes.
Any ideas? I’m using SQLBindParameter to bind the columns, and all of the calls succeed. I get the exception when I execute the insert statement. This same code worked for previous versions of Oracle (11g, 10g, and 9i). And if I use an 11g client driver against the 12c server, I do not get the exception.
Thanks!

Sorry, I was just now able to install the patch for bug 18232462, and it did indeed solve the issue I described above. Thanks!

BCP-style bulk insert from remote C++ ODBC Native client application

I am trying to find documentation or sample code for performing bulk inserts into SQL Server 2012 from a remote client using the ODBC native client driver from Linux. We currently perform INSERT statements on blocks of data, wrapping it in BEGIN/COMMIT,
and achieving through approximately half of bcp reading from a delimited text file. While there are many web pages talking about bulk inserts via the native driver, this page (http://technet.microsoft.com/en-us/library/ms130792.aspx) seems closest to
what I'm after but doesn't go into any detail or give API calls. The referenced header file is just a bunch of options and constants, so presumablyone gains access to bulk functions via the standard ODBC mechanism, the question is how.
For clarity, I am NOT interested in:
BULK INSERT: because it requires a server-side data file or a UNC path with appropriate permissions (doesn't work from Linux)
INSERT ... SELECT
* FROM OPENROWSET(BULK...): same problem as above
IRowsetFastload: OLEDB, but I need ODBC on Linux.
Basically, I want to emulate BCP. I don't want to *run* BCP because it requires landing data to disk.
Thanks

Other than block inserts within BEGIN/COMMIT transaction blocks or running bcp, is there anything else that can be done on Linux?
No other option from Linux that I am aware of. The SQL Server Native Client ODBC driver also supports table-valued-parameters, which can be used to stream data but the Linux ODBC driver API doesn't have a way to do that either. That said, I would
still expect file-based BCP to significantly outperform inserts with large batches. I've seen a rate of 100K/sec. with this technique, including the file create overhead but much depends on the particulars of your use case.
Consider voting for this on Connect. BCP is on the roadmap but no date yet:
https://connect.microsoft.com/SQLServer/SearchResults.aspx?SearchQuery=linux+odbc+bcp
Also, I filed a Connect item for TVP support:

Running INSERT into SQL Server using Heterogeneous Services

I am running into a show stopping issue trying to insert into a SQL Server table via Oracle.
Basically, I have my Heterogeneous Services set up correctly and I am able to hit the SQL Server database with my INSERT statement. But what is happening is I seem to be manually controlly row locks. I believe HS is issuing the following to the server before my INSERT statement is run:
SET TRANSACTION ISOLATION LEVEL READ COMMITTED
SET IMPLICIT_TRANSACTIONS ON
Also, it does not seem that I ever issue the COMMIT TRANSACTION
command. This leaves the row locked forever... unable to complete the
insert generating an error and not inserting my record.
I would GREATLY appreciate any help you could provide, this is a critical issue.
Thanks in advance,
