Description:
------------
It seems that Ingres PHP extension does not handle empty strings correctly in prepare staments.

Reproduce code:
---------------
http://ingres.pastebin.com/d1ebcc134

Expected result:
----------------
No errors, it should successfully execute the insert statement.

SQL session (begin) -----------------------
continue
* insert into simple_table(val1,val2) values('','');\g
Executing . . .

(1 row)
continue
SQL session (end) -----------------------

As you can see it is a perfectly valid statement.

Actual result:
--------------
Connection succeeded.PHP Warning:  ingres_query(): ii_success : Server or API error - no error message available, status 8 in /home/dejan/tingres.php on line 23
PHP Stack trace:

Can you try the patch at http://ingres.pastebin.com/f6fd0d64f. It needs to be applied to SVN headrevs.
 [2009-10-29 05:31 UTC] grant dot croker at ingres dot com 
This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.
