Getting raw SQL query string from PDO prepared statements

Question

Is there a way to get the raw SQL string executed when calling PDOStatement::execute() on a prepared statement? For debugging purposes this would be extremely useful.

Answer 1

The $queryString property mentioned will probably only return the query passed in, without the parameters replaced with their values. In .Net, I have the catch part of my query executer do a simple search replace on the parameters with their values which was supplied so that the error log can show actual values that were being used for the query. You should be able to enumerate the parameters in PHP, and replace the parameters with their assigned value.
