# db2_conn_error

(PECL ibm_db2 >= 1.0.0)

db2_conn_error — Returns a string containing the SQLSTATE returned by the last connection attempt

### 설명

string db2_conn_error ([ resource `$connection` ] )

db2_conn_error() returns an SQLSTATE value representing the reason the last attempt to connect to a database failed. As db2_connect() returns `FALSE` in the event of a failed connection attempt, you do not pass any parameters to db2_conn_error() to retrieve the SQLSTATE value.

If, however, the connection was successful but becomes invalid over time, you can pass the `connection` parameter to retrieve the SQLSTATE value for a specific connection.

To learn what the SQLSTATE value means, you can issue the following command at a DB2 Command Line Processor prompt: `db2 '? `sqlstate-value` '` . You can also call db2_conn_errormsg() to retrieve an explicit error message and the associated SQLCODE value.

### 인수

`connection`

  A connection resource associated with a connection that initially succeeded, but which over time became invalid.

### 반환값

Returns the SQLSTATE value resulting from a failed connection attempt. Returns an empty string if there is no error associated with the last connection attempt.

### 예제

Example #1 Retrieving an SQLSTATE value for a failed connection attempt

The following example demonstrates how to return an SQLSTATE value after deliberately passing invalid parameters to db2_connect().

`<?php
$conn = db2_connect('badname', 'baduser', 'badpassword');
if (!$conn) {
print "SQLSTATE value: " . db2_conn_error();
}
?>`

위 예제의 출력:

    SQLSTATE value: 08001
