Status Parameters for prepared statements

#define SQLITE_STMTSTATUS_FULLSCAN_STEP     1
#define SQLITE_STMTSTATUS_SORT              2
#define SQLITE_STMTSTATUS_AUTOINDEX         3

These preprocessor macros define integer codes that name counter values associated with the sqlite3_stmt_status() interface. The meanings of the various counters are as follows:

SQLITE_STMTSTATUS_FULLSCAN_STEP

This is the number of times that SQLite has stepped forward in a table as part of a full table scan. Large numbers for this counter may indicate opportunities for performance improvement through careful use of indices.

SQLITE_STMTSTATUS_SORT

This is the number of sort operations that have occurred. A non-zero value in this counter may indicate an opportunity to improvement performance through careful use of indices.

SQLITE_STMTSTATUS_AUTOINDEX

This is the number of rows inserted into transient indices that were created automatically in order to help joins run faster. A non-zero value in this counter may indicate an opportunity to improvement performance by adding permanent indices that do not need to be reinitialized each time the statement is run.
