Does that help I think it's not to answer, as it comes from the deepest parts of CGImage. I have noticed this error myself several times in the simulator. As you have noticed, I can confirm that it doesn't do anything. Everything looks as expected.
Reading file contents and appending a string to it - SQL Errors and mysql errors
seems to work fine For question 1 you should simply, not pass any argument to the mysql_num_rows() if you only have one database connection. For question 2, the escaped version should not produce a different hash as long as it has been saved to the database, and then pulled from the database again. Once an escaped string is saved to the database, the saved version effectively loses the escape characters. This is why you do not see "they\'re" for example, when you pull escaped values from the database.
