== Details ==
*&$updateFields: an array containing a list of field configurations. Each configuration is in the form <code>array( $tableName, $idField, $textField, 'batchKey' => $batchKey, 'options' => $options, 'db' => $db )</code>. Everything except <code>$tableName</code> and <code>$idField</code> is optional.
** $tableName: name of the table containing the field(s) to update
** $idField: field containing the user ID
** $textField: field containing the username
** $batchKey: primary key of the table. If present, update will be done in batches.
** $options: options array for [[Manual:Database_access#Wrapper_functions|Database::update()]]. Typically used to ignore duplicate keys.
** $db: DB connection to use

If the update operation is too complex to be handled this way, {{hook|MergeAccountFromTo|extension=UserMerge}} can be used instead.
