Terminates a connection to a data source.
SQLDISCONNECT(nStatementHandle) |
Parameters
- nStatementHandle
- Specifies the statement handle to the data source returned by SQLCONNECT(В ). Specify 0 for nStatementHandle to terminate all active connections.
Return Value
Numeric. SQLDISCONNECT( ) returns 1 if the connection is successfully terminated, – 1 if there is a connection level error, and – 2 if there is an environment level error.
Remarks
SQLDISCONNECT(В ) terminates a connection to a data source. You must supply the statement handle that SQLCONNECT(В ) returned when you established the connection.
 Note: |
|---|
| If you execute SQLDISCONNECT(В ) within an asynchronous function sequence or during a transaction, SQLDISCONNECT(В ) generates an error. |
Example
The following example assumes an ODBC data source called MyFoxSQLNT is available. SQLCONNECT(В ) is issued, and its return value is stored to a variable named gnHandle.
If you successfully connect to the data source, SQLCONNECT(В ) returns a positive number, a dialog box is displayed and SQLDISCONNECT(В ) is used to disconnect from the data source.
If you cannot connect to the data source, SQLCONNECT(В ) returns a negative number and a message is displayed.
| В |  Copy Code |
|---|---|
STORE SQLCONNECT('MyFoxSQLNT', '<userid>', '<password>') TO gnHandle
IF gnHandle <= 0
= MESSAGEBOX('Cannot make connection', 16, 'SQL Connect Error')
ELSE
= MESSAGEBOX('Connection made', 48, 'SQL Connect Message)
= SQLDISCONNECT(gnHandle)
