Error Codes And Messages

int sqlite3_errcode(sqlite3 *db);
const char *sqlite3_errmsg(sqlite3*);
const void *sqlite3_errmsg16(sqlite3*);

The sqlite3_errcode() interface returns the numeric result code or extended result code for the most recent failed sqlite3_* API call associated with a database connection. If a prior API call failed but the most recent API call succeeded, the return value from sqlite3_errcode() is undefined.

The sqlite3_errmsg() and sqlite3_errmsg16() return English-language text that describes the error, as either UTF-8 or UTF-16 respectively. Memory to hold the error message string is managed internally. The application does not need to worry about freeing the result. However, the error string might be overwritten or deallocated by subsequent calls to other SQLite interface functions.

If an interface fails with SQLITE_MISUSE, that means the interface was invoked incorrectly by the application. In that case, the error code and message may or may not be set.
