PDO::errorInfo — Fetch extended error information associated with the last operation on the database handle

说明

public PDO::errorInfo(): array

参数

此函数没有参数。

返回值

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

注意:
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.

范例

示例 #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());
}
?>

以上例程会输出：

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());

}

?>

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 */

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

)

I don't know why mazen at mindcraftinc dot com is getting that amount of negative votes: in my case, I've constated that with odbc_driver and an Access database, this method is returning ONE extra field appart from what is stated in this manual.
More precisely, if using the PDO odbc_pdo driver with an Access database, in a fourth array element I'm getting the ODBC Status Return Code.
