PRB: ODBC Error 01000 (-1): ConnectionOpen (sopen())

• Microsoft FoxPro for Windows, versions 2.5, 2.5a, 2.5b
• Microsoft FoxPro Connectivity Kit, version 2.5

SYMPTOMS

When you are trying to connect to an SQL Server machine with a DBConnect() function, you receive the following error message from DBError():

ODBC error 01000 (-1): [Microsoft][ODBC SQL Server Driver][dbnmp3] ConnectionOpen (sopen()).

RESOLUTION

The error is caused by an incorrect server name in the ODBC Driver Manager's Setup application in the Control Panel.

MORE INFORMATION

The following steps and code reproduce the problem using an SQL Server:

1. In the Control Panel, open the ODBC Driver Manager and set up a SQL Data Source with the following information:

   
         Data Source Name: test
         Description: test
         Server: WRONG_SRV 

   NOTE: WRONG_SRV is a nonexistent server name; if the correct server name appears in the ODBC Driver Manager's Setup for the driver, the example below will return a valid connection.
   
   The server name will vary depending upon the network and the actual name that the server's administrator has given the server. For more information about setting up the correct server name for the network in use, choose the Help button and look under the section for "Server."



2. Type in the following program and run it:

   
         SET LIBRARY TO SYS(2004)+"fpsql.fll"
         PUBLIC errval
         PUBLIC errmsg
         PUBLIC handle
   
         errval=0
         errmsg=' '
         sourcename= 'test      '  && This is the source name specified
                                   && in the ODBC Driver Manager.
   
         user= 'sa'                && This is your user ID for SQL
                                   && Server.
   
         passwd=''                 && Password for the user ID on the
                                   && line above.
   
         ********CONNECT
   
         handle=DBConnect(sourcename,user,passwd)
         IF handle > 0
            WAIT WINDOW 'Successfully Connected' nowait
         ELSE
            error=DBError(0,@errmsg,@errval)
            WAIT WINDOW STR(error)+' '+STR(errval)+' '+errmsg
         ENDIF
