The DB_SEQUENCE->stat() method creates a statistical structure and copies a pointer to it into user-specified memory locations. Specifically, if spp is non-NULL, a pointer to the statistics for the database are copied into the memory location to which it refers.

Statistical structures are stored in allocated memory. If application-specific allocation routines have been declared (see DB_ENV->set_alloc() for more information), they are used to allocate the memory; otherwise, the standard C library malloc(3) is used. The caller is responsible for deallocating the memory. To deallocate the memory, free the memory reference; references inside the returned memory need not be individually freed.

In the presence of multiple threads or processes accessing an active sequence, the information returned by DB_SEQUENCE->stat() may be out-of-date.

The DB_SEQUENCE->stat() method cannot be transaction-protected. For this reason, it should be called in a thread of control that has no open cursors or active transactions.

The DB_SEQUENCE->stat() method returns a non-zero error value on failure and 0 on success.

The statistics are stored in a structure of type DB_SEQUENCE_STAT. The following fields will be filled in:



The flags parameter must be set by bitwise inclusively OR'ing together one or more of the following values:


    Display all available information.


    Reset statistics after printing their values.
