Body
<p>Not sure why sqlite3_prepare_v2 equals false. I've searched around online and couldn't find much and what I did find didn't help. One site suggested to using sqlite3_errmsg(database) and this outputted "not an error" for some reason. Another answer online suggested deleting a folder in the iPhone simulator which is named with a string hex, but that didn't work either. I made my database and dropped into the supporting files folder so it is there and it has records.</p> <p>This is my code:</p> <pre><code>-(void)readMovesFromDatabaseWithPath:(NSString *)filePath { sqlite3 *database; printf("Here in readMovesFromDatabaseWithPath\n"); if(sqlite3_open([filePath UTF8String], &database) == SQLITE_OK) { NSLog(@"Now in readMovesFromDatabaseWithPath\n"); const char *sqlStatement = "select * from moves"; sqlite3_stmt *compiledStatment; printf( "could not prepare statemnt: %s\n", sqlite3_errmsg(database) ); //returns "not an error" if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatment, NULL) == SQLITE_OK) { NSLog(@"In sqlite3_prepare_v2 block\n"); //does not reach this line while(sqlite3_step(compiledStatment) == SQLITE_ROW) //Loops through the database { //Extracts the move's name NSString *moveName = [NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatment, 1)]; //Extracts the move's description NSString *moveDescription = [NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatment, 2)]; //Creates new move objects Moves *newMove = [[Moves alloc] init]; newMove.moveName = moveName; newMove.moveDescription = moveDescription; [self.moves addObject:newMove]; } } sqlite3_finalize(compiledStatment); } sqlite3_close(database); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
