PDO::errorInfo — Fetch extended error information associated with the last operation on the database handle
PDO::errorInfo() returns an array of error information about the last operation performed by this database handle. The array consists of the following fields:
| Element | Information |
|---|---|
| 0 | SQLSTATE error code (a five characters alphanumeric identifier defined in the ANSI SQL standard). |
| 1 | Driver-specific error code. |
| 2 | Driver-specific error message. |
Hinweis:
If the SQLSTATE error code is not set or there is no driver-specific error, the elements following element 0 will be set to NULL.
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 not reflect the error from the statement handle. You must call PDOStatement::errorInfo() to return the error information for an operation performed on a particular statement handle.
Beispiel #1 Displaying errorInfo() fields for a PDO_ODBC connection to a DB2 database
<?php
/* Provoke an error -- bogus SQL syntax */
$stmt = $dbh->prepare('bogus sql');
if (!$stmt) {
echo "\nPDO::errorInfo():\n";
print_r($dbh->errorInfo());
}
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
PDO::errorInfo():
Array
(
[0] => HY000
[1] => 1
[2] => near "bogus": syntax error
)
Please note : that this example won't work if PDO::ATTR_EMULATE_PREPARES is true.
You should set it to false
<?php
$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES,false);
$stmt = $dbh->prepare('bogus sql');
if (!$stmt) {
echo "\nPDO::errorInfo():\n";
print_r($dbh->errorInfo());
}
?>
Some PDO drivers return a larger array. For example, the SQL Server driver returns 5 values.
For example:
<?php
$numRows = $db->exec("DELETE FROM [TableName] WHERE ID between 6 and 17");
print_r($db->errorInfo());
?>
Result:
Array
(
[0] => 00000
[1] => 0
[2] => (null) [0] (severity 0) []
[3] => 0
[4] => 0
)
here are the error codes for sqlite, straight from their site:
The error codes for SQLite version 3 are unchanged from version 2. They are as follows:
#define SQLITE_OK 0 /* Successful result */
#define SQLITE_ERROR 1 /* SQL error or missing database */
#define SQLITE_INTERNAL 2 /* An internal logic error in SQLite */
#define SQLITE_PERM 3 /* Access permission denied */
#define SQLITE_ABORT 4 /* Callback routine requested an abort */
#define SQLITE_BUSY 5 /* The database file is locked */
#define SQLITE_LOCKED 6 /* A table in the database is locked */
#define SQLITE_NOMEM 7 /* A malloc() failed */
#define SQLITE_READONLY 8 /* Attempt to write a readonly database */
#define SQLITE_INTERRUPT 9 /* Operation terminated by sqlite_interrupt() */
#define SQLITE_IOERR 10 /* Some kind of disk I/O error occurred */
#define SQLITE_CORRUPT 11 /* The database disk image is malformed */
#define SQLITE_NOTFOUND 12 /* (Internal Only) Table or record not found */
#define SQLITE_FULL 13 /* Insertion failed because database is full */
#define SQLITE_CANTOPEN 14 /* Unable to open the database file */
#define SQLITE_PROTOCOL 15 /* Database lock protocol error */
#define SQLITE_EMPTY 16 /* (Internal Only) Database table is empty */
#define SQLITE_SCHEMA 17 /* The database schema changed */
#define SQLITE_TOOBIG 18 /* Too much data for one row of a table */
#define SQLITE_CONSTRAINT 19 /* Abort due to contraint violation */
#define SQLITE_MISMATCH 20 /* Data type mismatch */
#define SQLITE_MISUSE 21 /* Library used incorrectly */
#define SQLITE_NOLFS 22 /* Uses OS features not supported on host */
#define SQLITE_AUTH 23 /* Authorization denied */
#define SQLITE_ROW 100 /* sqlite_step() has another row ready */
#define SQLITE_DONE 101 /* sqlite_step() has finished executing */
here is a reference to the ansi error codes
there are several others;
a link to the official spec from ansi would be nice
(have to rebuild this link because its too long to post w/o breaking it up)

The example code is incorrect. The line that reads:
$err = $dbh->prepare('SELECT skull FROM bones');
Will set the value of $err to be boolean FALSE.
So, to get a useful error dump change this line:
print_r($err->errorInfo());
to:
print_r($dbh->errorInfo());
