Error handling


Handling errors is mandatory when writing systems, especially if it is for mobile devices; so, attention to detail and catching issues with code is vital. The SQLITE_BUSY and SQLITE_ERROR functions are used by programmers to notify and trap errors, and store them for a later analysis.

For example, SQL_ERROR is activated when resources such as locks cannot be granted or are not available, whereas the SQL_BUSY covers issues with transactions and related matters. Another function called sqlite3_errcode() will handle any general SQLite error. These methods and functions are the standard way of handling errors with SQLite.
