Data type Argument Use Description
SQLSMALLINT HandleType input Handle Type.
SQLHANDLE Handle input Connection handle.
SQLSMALLINT CompletionType input How to complete the active operations associated with a connection.

Usage

HandleType
Handle type identifier. Only SQL_HANDLE_DBC (a connection handle) is allowed.

Handle
The handle, of the type indicated by HandleType.

CompletionType
One of the following two values:

In manual-commit mode, SQLEndTran() must be called before calling SQLDisconnect(). If SQLEndTran() is not called before SQLDisconnect(), the operations that updated the database (since the last transaction started) are rolled back.

When a ROLLBACK is performed, all the statement handles are cleared.

If the application crashes or terminates prematurely during use in manual mode, the updates since the last COMMIT are lost. SQLEndTran() must be called before calling disconnect.
