PDO::errorInfo — 获取与数据库句柄上最后一次操作相关的扩展错误信息
此函数没有参数。
PDO::errorInfo() 返回一个包含此数据库句柄上最后一次操作的错误信息的数组。该数组至少包含以下字段：
| 元素 | 信息 |
|---|---|
| 0 | SQLSTATE 错误码（由 ANSI SQL 标准定义的五个字符的字母数字标识符）。 |
| 1 | 驱动程序特定的错误码。 |
| 2 | 驱动程序特定的错误信息。 |
注意:
如果没有设置 SQLSTATE 错误码或驱动程序没有报告特定错误，则元素 0 之后的元素将被设置为
null。
PDO::errorInfo() 仅获取直接在数据库句柄上执行的操作的错误信息。如果通过 PDO::prepare() 或 PDO::query() 创建 PDOStatement 对象，并在语句句柄上产生错误，PDO::errorInfo() 将不会反映语句句柄上的错误。必须调用 PDOStatement::errorInfo() 来返回在特定语句句柄上执行的操作的错误信息。
示例 #1 显示连接到 DB2 数据库的 PDO_ODBC 的 errorInfo() 字段
<?php
/* 引发一个错误——虚假的 SQL 语法 */
$stmt = $dbh->prepare('bogus sql');
if (!$stmt) {
echo "\nPDO::errorInfo():\n";
print_r($dbh->errorInfo());
}
?>以上示例会输出：
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
)
