PDO::errorInfo

说明

返回值

PDO::errorInfo() returns an array of error information about the last operation performed by this database handle. The array consists of the following fields:

PDO::errorInfo() only retrieves error information for operations performed directly on the database handle. If you create a PDOStatement object through PDO::prepare() or PDO::query() and invoke an error on the statement handle, PDO::errorInfo() will insert an error code of PDO_ERR_NONE into the first element of the returned array. You must call PDOStatement::errorInfo() to return the error information for an operation performed on a particular statement handle.
