C API Reference -- Ns_DbCancel

### Ns_DbCancel

#### Overview

Cancel an active SQL select statement

#### Syntax

        int Ns_DbCancel(
        Ns_DbHandle *handle
        );

#### Description

The Ns_DbCancel function is similar to the Ns_DbFlush function, but instead of allowing the select statement to complete and send all selected rows, Ns_DbCancel sends a cancels message to the database. This can result in faster interruption of a long-running query. Ns_DbCancel returns NS_OK on success and NS_ERROR on error.
