New Comment:
If I make a query against the database using a stored procedure, in my
case I use the following code...
$counterQuery = $db->query("CALL getSpecificDownloadCounter(?, ?);",
array($counterName, $fileFolder));
if ($counterQuery->numRows() != 0) {
$result = $db->query("CALL advanceDownloadCounter(?, ?);",
array($counterName, $fileFolder));
if (PEAR::isError($result)) die($result->getMessage());
}
The isError line will return "DB Error: no database selected". If I add
the following line of code to mysqli.php...
if (preg_match('/\ACALL.*/im', $query))
$this->connection->next_result();
Right after...
$result = @mysqli_query($this->connection, $query);
On line 400, the next query I make executes properly.
According to MySQL documentation, if you execute a stored procedure you
must execute next_result() or the next query will fail.

Hi Tom:
Thank you for the patch. Please upgrade DB to version 1.9.2 without the
patch. If the problem persists, please write a short reproduce script
that makes a connection, creates a sample database and stored procedure,
executes the stored procedure then drops the database.

Description:
------------
After calling a MySQL Stored Procedure in MySQLi mode, you are unable to
execute another query after it. When you try to it tells you that you
have no database selected.
In order to fix this issue, you must patch mysqli.php file and add this
line...
if (preg_match('/\ACALL.*/im', $query))
$this->connection->next_result();
After this line (line 400)...
$result = @mysqli_query($this->connection, $query);
