Here, the first argument sqlite3 is an open database object, sqlite_callback is a call back for which data is the 1st argument and errmsg will be returned to capture any error raised by the routine. This routine provides a quick, easy way to execute SQL commands provided by sql argument which can consist of more than one SQL command. Sqlite3_exec(sqlite3*, const char *sql, sqlite_callback, void *data, char **errmsg) If no file by that name exists, sqlite3_open() will open a new database file by that name. If the filename is not NULL, sqlite3_open() attempts to open the database file by using its value.

Sqlite3_open(const char *filename, sqlite3 **ppDb) If you are looking for a more sophisticated application, then you can look into SQLite official documentation. C/C++ Interface APIsįollowing are important C/C++ SQLite interface routines, which can suffice your requirement to work with SQLite database from your C/C++ program. You can check SQLite Installation chapter to understand the installation process.
