maxdb_error


(PECL maxdb >= 1.0)

maxdb_errorReturns a string description of the last error

Beschreibung

Procedural style:

string maxdb_error ( resource $link )

Object oriented style (property)

maxdb
string $error;

The maxdb_error() function is identical to the corresponding maxdb_errno() function in every way, except instead of returning an integer error code the maxdb_error() function will return a string representation of the last error to occur for the database connection represented by the link parameter. If no error has occured, this function will return an empty string.

Rückgabewerte

A string that describes the error. An empty string if no error occurred.

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

PHP Warning:  maxdb_query(): -4005 POS(8) Unknown column name:XXX [42000]
Errormessgae: POS(8) Unknown column name:XXX
