Secondary database conections

Question

i’m working in a proyect, that consist in send data to other db server that is not on the r3 database server,
both database server are running on SQL Server 2000.
The version of sap is 46b.
S.O. Windows 2000 SERVER
THe secondary database is in Windows 2000 Server too.
i found information in the notes: 313151,178949.
i fill the table dbcon as follow:
Connection name : SAPPVF   
DBMS:MSS                   
User name: csappvf                                    
DB password *** / ********+
Conn. info: MSSQL_SERVER=NHUERTA MSSQL_DBNAME=PRU
csappvf, is the user with permision dbo in database PRU.
Where NHUERTA, is secondary server, where is the database PRU.
PRU, is the secondary database
  Code program abap.
EXEC sql.
  CONNECT TO 'SAPPVF' AS 'MIM'
ENDEXEC.
EXEC SQL.
     SET CONNECTION 'MIM'
ENDEXEC.
IF SY-SUBRC = 0.
    EXEC SQL.
      SET CONNECTION 'MIM'
    ENDEXEC.
    EXEC SQL.
      SELECT single * INTO :WA_RENTA FROM RENTA
    ENDEXEC.
   but the program generate a dump:
ABAP/4 Program ZMX_BC_IN_CONEXION
vSource ZMX_BC_IN_CONEXION
Line 38.    
<b>Error Code DBIF_DSQL2_OBJ_UNKNOWN. </b>               
Module  $Id: //bas/46D/src/krn/runt/abexsql.c#8 $ SAP.      
Function ExecuteCall Line 806

Hi Noemi,
1. As u said, you have a secondary database connection
   which is tested and working. (But giving
   error in ur Z program)
2. SAP recommends that instead of using NATIVE Sql,
   use OPEN Sql.
   So that if there is any change in database,
   the R/3 system(Database Manager) will automatically
   take care of it)
3. According to me, you should you OPEN Sql.
   To do this,
   you will have to create the same Z / Y table
   in your R/3 database, with the same structure.
   This can be a blank table or structure.
   SO THAT ABAP IDENTIFIES IT AS A DATABASE OBJECT
   IN DD DICTIONARY WHEN SYNTAX CHECKING THE SQL.
4.  One can use the following syntax.
      DATA: mydbcon(30) TYPE c. 
      mydbcon = 'SAPPVF'.
     Select * FROM YTABLE CONNECTION (mydbcon)
     into ITAB.
HOPE THIS HELPS
