I'm not well versed with SQL. I connect to a SQL database just to retrieve some data every 10 minutes. At times that server is down for updates. At such time my program stops. I would like to be able to test the connection before using it, skip it if not available. Here is what I do now:
ServerName='ServerName'
ServerPassword='ServerPass
hConn = SQLStringConnect("Driver=S
When it fails, I get the message "Microsoft SQL Server Login" "Conneciton failed: SQLState:'01000 etc.'' And then prompt me for a server name to log into. This needs to run un-attended.
Thanks.

Sorry, that particular function returns either a True or False. I was confusing it initially with having a returned handle reference to a connection.
IF hConn && successful connection and server is up and running
ELSE && NOT hConn -- no usable connection, come back later
ENDIF
SQLSTRINGCONNECT( ) Function

After I fumbled through the help and got to my initial thought on that connection handle, I finally realized you were really trying to trap for that error before it got thrown.
Do you have some sort of ON ERROR routine that will trap for errors in your program? You could easily trap for the eror number this throws and have your program divert to other things rather than assuming it connected.

SQLSETPROP( ) Function

Maybe something like:
*** Don't prompt for login
SQLSETPROP(0,"DispLogin",3

You should evaluate the value returned by hConn. If a non-postive number is returned, you don't have a usable connection.
IF hConn>0 && successful connection and server is up and running
ELSE && no usable connection, come back later
ENDIF
