Bypass the login screen when connecting to an Oracle database

Summary

Steps to bypass the login screen when making an SQL connection to an Oracle database on UNIX and PC platforms.

Procedure

• To make a SQL connection to an Oracle database from UNIX:
  
  1. Open a new script window.
  
  
  A. Activate the Project window.
  B. Click the Scripts icon.
  C. Click New.
  
  
  
  2. Copy the following code into the script window:
  
  

  Code:
  theSQL=SQLCon.Find("Oracle")
  theSQL.Login("user/password")
  astring="Select * from house1"
  theVTab=VTab.MakeSQL(theSQL, astring)
  myTable=Table.Make(theVtab) av.GetProject.AddDoc(mytable)
  mytable.GetWin.Open 

  
  
  

  Note:
  This script assumes that the environment variables needed to connect to Oracle have been set. 

  
  
  3. Click the Compile button.
  
  4. Click the Run button.
  
  
• To make a SQL connection to an Oracle database from a PC using ODBC:
  
  1. Create a Data Source Name (DSN) for the Oracle database.
  
  
  A. Click Start > Settings > Control Panel.
  B. Double-click the ODBC32 Administrator icon.
  C. Select the User DSN tab, then click the Add button.
  D. Select the Oracle ODBC Driver and click the Finish button.
  E. Type in a name for the DSN in the Data Source Name field, for example 'Addresses'.
  F. Enter the Service Name.
  G. Click OK.
  H. Click OK to close the ODBC Administrator dialog box.
  
  
  
  2. Open a new script window.
  
  3. Copy the following code into the script window:
  
  

  Code:
   theCon = SQLCon.Find("DSN NAME")
   theCon.Login("SRVR=orasan;UID=snoopy;PWD=snoopy")
   astring="Select * from house1"
   theVTab=VTab.MakeSQL(theCon, astring)
   myTable=Table.Make(theVtab)
   av.GetProject.AddDoc(mytable)
   mytable.GetWin.Open 

  
  
  Where 'SRVR' is the Oracle service name and 'astring' is a SQL statement that selects all of the fields from a table in the database. The following is an excerpt from the tnsnames.ora file where two different alias names/service names are defined as "san" and "rexx":
  
  

  san = (DESCRIPTION = 
          (ADDRESS = 
            (PROTOCOL = TCP) 
            (HOST = sanawar)
            (PORT = 1521)
          )
      (CONNECT_DATA =
          (SID = oracle7)
      )
    )
  
  rexx = (DESCRIPTION = 
          (ADDRESS = 
            (PROTOCOL = TCP)
            (HOST = rexx)
            (PORT = 1521)
          )
      (CONNECT_DATA = 
          (SID = sde30)
      )
    )
  

  
  
  4. Click the Compile button.
  
  5. Click the Run button.
