Prepared Statement Status
int
sqlite3_stmt_status
(sqlite3_stmt*,
int op, int resetFlg);
Each prepared statement maintains various SQLITE_STMTSTATUS counters that
measure the number of times it has performed specific operations. These
counters can be used to monitor the performance characteristics of the
prepared statements. For example, if the number of table steps greatly exceeds
the number of table searches or result rows, that would tend to indicate that
the prepared statement is using a full table scan rather than an index.
This interface is used to retrieve and reset counter values from a
prepared statement. The first argument is the prepared statement object to
be interrogated. The second argument is an integer code for a specific
SQLITE_STMTSTATUS counter to be interrogated. The current value of the
requested counter is returned. If the resetFlg is true, then the counter is
reset to zero after this interface call returns.
