1 新建或插入
sqlite3 *db;if (sqlite3_open(@"xx.db", &db) != SQLITE_OK ) {return;}sqlite3_stmt *dbps; int dbrc; NSString *sql = @"";const char *sqlChar = [sql UTF8String];dbrc = sqlite3_prepare_v2(db, sqlChar, -1, &dbps, NULL);dbrc = sqlite3_step(dbps);if(dbrc != SQLITE_DONE){NSLog(@"exec sql error!,sql:%@,error code:%d.",sql,dbrc);}sqlite3_finalize(dbps);sqlite3_close(db);sqlite3 *db;int dbrc;sqlite3_stmt *dbps;if (sqlite3_open(@"xx.db", &db) != SQLITE_OK ) {NSLog(@"couldnet't open db:");return;}NSString *sql = @"select * from sqlite3_master ";const char *sqlChar = [sql UTF8String]; dbrc = sqlite3_prepare_v2 (db, sqlChar, -1, &dbps, NULL);while ((dbrc = sqlite3_step (dbps)) == SQLITE_ROW) {NSLog([[NSString alloc] initWithUTF8String:(char*) sqlite3_column_text(dbps, 0)]);}sqlite3_finalize(dbps);sqlite3_close(db);
