    Raw SQL Queries

    doctrine dbal prepare I have a database that displays a list of items. Instead of all doctrine dbal prepare selected checkboxes being deleted, it's only the first of the testosterone amplifier methyl andro one that is being deleted. To paraphrase Dormilich's answer, SQL prepared statements cannot handle arrays. Which is doctrine dbal prepare real pain. Cbal are however libraries which do support this lrepare of behavior. And since you are moving your code to prepared statements then you might want to check them out. Doctrine 2's Database Access Layer is a good example:

    I have a database that displays a list of items. Instead of all the selected checkboxes being deleted, it's only the first of the checked one that is being deleted. To paraphrase Dormilich's answer, SQL prepared statements cannot handle arrays. Which is a real pain. There are however libraries which do support this sort of behavior.

    And since you are moving your code to prepared statements then you might want to check them out. Doctrine 2's Database Access Layer is a good example: Doctrine 2 also has some other goodies such as sql query builders and schema information. I thought I read something about that just the other day. PDO binds on a per-value basis. Why, I don't know? Maybe it works with it inside the loop as well. Maybe someone can explain that? It works because you are basically executing the prepared statement multiple times.

    I'm not sure what you mean by this, but you can bind array values to placeholder arguments using PDO:. I am guessing it is because it called in bind-param within prepare and execute even though is has not yet been defined from top to bottom.

    Doing it your way requires counting the number of ids and then building a place holder string. Not so bad for simple queries but becomes painful when you have multiple where clauses. It is just good to understand what it might be doing in the background. Try your solution and see what happens. You will get an array to string conversion error message.

I wish I could find that article again PDO does indeed support named parameters which I like better than positional? I found the article, but, as it seems, I misunderstood it. And then I found this. This is not the same thing as using PDOStatement:: I'm not sure what you mean by this, but you can bind array values to placeholder arguments using PDO: Go back to the opening post.

    Then you could just use myesain84's solution mixed with my solution, couldn't you? Out of the box, you cannot pass arrays as parameters using PDO. This is untested but basically you need: Forgot I need the placeholders.
