How To Execute a Stored Procedure on SQL Server

MORE INFORMATION

The following steps describe how to create a stored procedure on Microsoft SQL Server; this information has been presented as a matter of convenience and is not supported by FoxPro Product Support. For questions concerning the creation, syntax, or functionality of stored procedures, refer to the CREATE PROCEDURE command in the SQL Server "Language Reference," or contact SQL Server Product Support. The commands to create the stored procedure can also be executed with the SQLExec function from Visual FoxPro, or the DBExec() function from FoxPro 2.x. The steps set up a stored procedure on SQL Server and then explain how you execute the stored procedure from within Visual FoxPro or from FoxPro 2.x using the Connectivity Kit.

Setting Up a Stored Procedure on SQL Server 7.0

1. From the Programs menu select Microsoft SQL Server 7.0, and then choose Query Analyzer.
2. Connect to your server.
3. Choose the pubs database in the DB drop down.
4. Type in the following procedure:

   create procedure showsales @parm1 char(4)
   as
   select * from sales where stor_id=@parm1
   					

5. From the File menu, choose Save As and save the procedure as STOR_PRC.SQL.
   • Click the Execute button.

Setting Up FoxPro to Run a Stored Procedure

Run one of the following programs, depending on your version of FoxPro.

FoxPro 2.x Code:

   *****SET THE LIBRARY AND INITIALIZE VARS
   IF _DOS
      SET LIBRARY TO SYS(2004)+"fpsql.plb"
   ELSE
      SET LIBRARY TO SYS(2004)+"fpsql.fll"
   ENDIF
   PUBLIC errval
   PUBLIC errmsg
   PUBLIC handle
   errval=0
   errmsg=' '
   sourcename= 'test'
   user= 'sa'
   passwd=''

   ********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

   =DBSetOpt(handle,'Asynchronous',0)
   =DBSetOpt(handle,'BatchMode',1)
   =DBSetOpt(handle,'ConnTimeout',0)
   =DBSetOpt(handle,'Transact',1)
   =DBSetOpt(handle,'UseTable',0)

   err=DBExec(handle,'use pubs')
   DO errhand WITH err,'USE PUBS'

   **********THIS PROGRAM DEMOs HOW TO IMPLEMENT SQL WITH
   **********THE DBExec() FUNCTION

   sqlcomm= "execute showsales '7066'"
   err=DBExec(handle,sqlcomm)
   DO errhand WITH err,"DBExec(handle,"+sqlcomm+")"
   IF err > 0
      BROWSE
   ENDIF

   **********DISCONNECT
   err=DBDisconn(handle)
   DO errhand WITH err,"DBDisconn()"
   SET LIBRARY TO
   CLOSE ALL

   **********Error Handler Program
   PROCEDURE errhand
   PARAMETERS err,command
   IF err > 0
     WAIT WINDOW ALLTRIM(UPPER(command))+"Completed Successfully";
     NOWAIT
   ELSE
     WAIT WINDOW UPPER(command)+"NOT Completed Successfully"
     error=DBError(handle,@errmsg,@errval)
     WAIT WINDOW STR(error)+" "+STR(errval)+" "+errmsg
   ENDIF
   RETURN
				

Note that the program returns the two records that have 7066 as the stor_id.

Visual FoxPro Code:

   PUBLIC errval
   PUBLIC errmsg
   PUBLIC handle
   errval=0
   errmsg=' '
   sourcename= 'test'
   user= 'sa'
   passwd=''

   ********CONNECT

   * Turning on error display for connections
    =SQLSetProp(0,"DispWarning",.t.)

   handle=SQLConnect(sourcename,user,passwd)
   IF handle > 0
      WAIT WINDOW 'Successfully Connected' NOWAIT
   ENDIF

   ********Set some defaults
   =SQLSetProp(handle,'Asynchronous',.f.)
   =SQLSetProp(handle,'BatchMode',.t.)
   =SQLSetProp(handle,'ConnectTimeOut',0)
   =SQLSetProp(handle,'Transactions',1)


   err=SQLExec(handle,'use pubs')
   DO errhand WITH err,'USE PUBS'

   **********THIS PROGRAM DEMOs HOW TO IMPLEMENT SQL WITH
   **********THE SQLExec() FUNCTION

   sqlcomm= "execute showsales '7066'"
   err=SQLExec(handle,sqlcomm)
   DO errhand WITH err,"SQLExec(handle,"+sqlcomm+")"
   IF err > 0
      BROWSE
   ENDIF

   **********DISCONNECT
   err=SQLDisconnect(handle)
   DO errhand WITH err,"SQLDisconnect()"
   CLOSE ALL

   **********Error Handler Program
   PROCEDURE errhand
   PARAMETERS err,command
   IF err > 0
     WAIT WINDOW ALLTRIM(UPPER(command))+"Completed Successfully";
     NOWAIT
   ELSE
     WAIT WINDOW UPPER(command)+"NOT Completed Successfully"
   ENDIF
   RETURN
				

Note that the program returns the two records that have 7066 as the stor_id.
