SQLDISCONNECT( ) Function Example

The following example assumes an ODBC data source called MyFoxSQLNT is available, and the user ID for the data source is "sa." SQLCONNECT( ) is issued, and its return value is stored to a variable named gnConnHandle.

If you successfully connect to the data source, SQLCONNECT( ) returns a positive number, a dialog is displayed and SQLDISCONNECT( ) is used to disconnect from the data source.

If you cannot connect to the data source, SQLCONNECT( ) returns a negative number and a message is displayed.

STORE SQLCONNECT('MyFoxSQLNT', 'sa') TO gnConnHandle
IF gnConnHandle <= 0
   = MESSAGEBOX('Cannot make connection', 16, 'SQL Connect Error')
ELSE
   = MESSAGEBOX('Connection made', 48, 'SQL Connect Message)
   = SQLDISCONNECT(gnConnHandle)
