Lorna Mitchell's Blog:
Handling SQL Errors in PDO
November 16, 2011 @ 09:43:34

Lorna Mitchell has a quick new post showing one way to handle SQL errors in PDO that could pop up because of badly written/generated SQL statements.

I love PHP's PDO (PHP Data Objects) extension; it gives a consistent, object-oriented interface to handling all kinds of relational database backends. One thing that annoys me is that the MySQL driver for PDO defaults to a silent error mode which can make SQL errors tricky to spot!

In her two code snippets she shows a failing PDO request (that fails silently) and a method for catching this issue - checking the result of the "errorCode" method to see if it equals "0" (zero). If there were errors, you can use the "errorInfo" function to get to them. This will return the SQL error code, the driver-specific error code and a driver-specific error message.
