ODBC Connection

ODBC Connection

ODBC Connection

(OP)
I am running a Internet wc Server app that relies heavy on ODBC data. To keep connection overhead down to a minimum I init the var=sqlconnect() when the wc server starts up I then reference the var throughout. My problem is when the Unix Box (ODBC Data Source)goes down or is rebooted I lose the connection and this results in an error on the next call. What I am looking for is a method to test the ConnectionHandle from time to time and if it dosn't exsist re-establish it I have tried several different ways to do this and none of them work very well. Any suggestions??

RE: ODBC Connection

My .02,

*Establish an error handler routine
ON ERROR DO ERRORHANDLER WITH ERROR( ), MESSAGE( )
*Allow the user to configure the connection
VAR=SQLCONNECT()
*Store the connection string for subsequent connections
CONSTRING=SQLGETPROP(VAR,'CONNECTSTRING')
*blah
*blah
*blah

PROCEDURE ERRORHANDLER
  PARAMETER merror, mess

  IF merror=1466 && connection handle is invalid
    *Use the connectstring the user configured earlier
    VAR=SQLSTRINGCONNECT(CONSTRING)
    *Check for success
    IF VAR<=0
      MESSAGEBOX('Connection cant be established.',0,'Boo!')
    ENDIF
  ENDIF
ENDPROC
