# db2_conn_errormsg

(PECL)

db2_conn_errormsg -- Returns the last connection error message and SQLCODE value

## Описание

string db2_conn_errormsg ( [resource connection] )

db2_conn_errormsg() returns an error message and SQLCODE value representing the reason the last database connection attempt failed. As db2_connect() returns `FALSE` in the event of a failed connection attempt, do not pass any parameters to db2_conn_errormsg() to retrieve the associated error message and SQLCODE value.

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

## Список параметров

`connection`

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

## Возвращаемые значения

Returns a string containing the error message and SQLCODE value resulting from a failed connection attempt. If there is no error associated with the last connection attempt, db2_conn_errormsg() returns an empty string.

## Примеры

Пример 1. Retrieving the error message returned by a failed connection attempt

The following example demonstrates how to return an error message and SQLCODE value after deliberately passing invalid parameters to db2_connect().

`<?php $conn = db2_connect('badname', 'baduser', 'badpassword'); if (!$conn) { print db2_conn_errormsg(); } ?>`

Результат выполнения данного примера:

    [IBM][CLI Driver] SQL1013N  The database alias name
    or database name "BADNAME" could not be found.  SQLSTATE=42705
     SQLCODE=-1013
