C API Reference -- Ns_DbFlush

### Ns_DbFlush

#### Overview

Flush any waiting rows

#### Syntax

        int Ns_DbFlush(
        Ns_DbHandle *handle
        );

#### Description

The Ns_DbFlush function fetches and dumps any waiting rows after an Ns_DbSelect. This function is useful when you have already fetched all the rows you intend to process. Ns_DbFlush returns NS_OK after successfully flushing the database or NS_ERROR on error.

Ns_DbFlush is called automatically when Ns_DbHandle's are returned to their pools with the Ns_DbPutHandle function to make sure the handle is ready the next time it is used.

Some database drivers will also cancel any active transactions when Ns_DbFlush is called.
