const char* sqlite3_errmsg( sqlite3* db ); const void* sqlite3_errmsg16( sqlite3* db );
db
A database connection.
Human-readable error message, in English.
This function returns the error message from the last failed
sqlite3_* API call
associated with this database connection. If a failed call was
followed by a successful call, the results are undefined.
Most of SQLite’s built-in error messages are extremely terse and somewhat cryptic. Although the error messages are useful for logging and debugging, most applications should provide their own end-user error messages.
If SQLite is being used in a threaded environment, this function
is subject to the same concerns as sqlite3_errcode().
If an API call returns SQLITE_MISUSE, it indicates an application
error. In that case, the result code may or may not be available
to sqlite3_errmsg().
