Bug description: ibase_query(): message length error
Description:
------------
I use a number of if statements to select an SQL string (in this case to
execute a stored procedure in a firebird database)to go in a $query
variable.
When the string is created and ran as a query the following is kicked out
onto the screen:
ibase_query(): message length error(encountered 0, expected 7346) in ....
a typical sql string generated may be:
EXECUTE PROCEDURE SEARCH_ALL_PARAM('Teesside','business
planning','Middlesbrough','the');
The parameters are taken from 4 fields on a search web page.
Reproduce code:
---------------
//Stored procedures used:
//SEARCH_NO_PARAM - where all the search boxes have 'any' and keyword ''
if ($provider == "any" && $level == "any" && $location == "any" &&
$keyword == "")
{
$query = "EXECUTE PROCEDURE SEARCH_NO_PARAM;";
}
//SEARCH_ALL_PARAM - where all the search boxes have information.
if ($provider != "any" && $level != "any" && $location != "any" &&
$keyword != "")
{
$query = "EXECUTE PROCEDURE
SEARCH_ALL_PARAM('".$provider."','".$level."','".$location."','".$keyword."');";
}
// ### some $query removed to keep things brief. ###
?>
<div align="center"><font size="+1"><strong>Queries and Reports
about the
courses :</strong> </font> </div>
<p align="center">
<input name="submit" type="submit" value="back and change
search">
<input name="button2" type="button"
onClick="window.location.replace('Query.php')" value="new search">
<input name="button2" type="button"
onClick="window.location.replace('information_syllabus.php')" value="main
menu">
</p>
</form>
<div align="center">
<table width="100%" border="1">
<tr bgcolor="#e0ffe0">
<td>Course Title</td>
<td bgcolor="#e0ffe0">Location</td>
<td>Entry requirements</td>
</tr>
<?
$result = ibase_query($db, $query);
while ($row =
ibase_fetch_object($result)) {?>
<tr bgcolor="#f0fffe">
<td><a href="coursedetail.php?courseid=<? echo
$row->ENTRYID;?>"><? echo $row->COURSETITLE;?></a></td>
<td bgcolor="#f0fffe">
<?
if ($location=="any"){
$query2 = "SELECT *
FROM TBL_MODULE_DELIVERY Where
ENTRYID='".$row->ENTRYID."'";
} else {
$query2 = "SELECT *
FROM TBL_MODULE_DELIVERY Where
ENTRYID='".$row->ENTRYID."' AND DELIVERYTOWN='".$location."'";
}
echo "University provider : ";
if (isset
($row->PROVIDERINSTITUTION) &&
$row->PROVIDERINSTITUTION!="") {echo $row->PROVIDERINSTITUTION;}else{ echo
" - ";}
echo "<BR> Delivery Town of
Location(s): ";
$result2 = ibase_query($db,
$query2);
while ($row2 =
ibase_fetch_object($result2)) {
if (isset
($row2->DELIVERYTOWN) && $row2->DELIVERYTOWN!=""){
echo
$row2->DELIVERYTOWN." - ";
} else {
echo " - ";
}
} ?>
Expected result:
----------------
return a result set from a search of courses in a firebird database.
Actual result:
--------------
$query echoed to screen to see if search string right:
EXECUTE PROCEDURE SEARCH_ALL_PARAM('Teesside','business
planning','Middlesbrough','the');
Then the warning message:
Warning: ibase_query(): message length error (encountered 0, expected
7346) in c:\program files\apache
group\apache\htdocs\e_prospectus\results.php on line 252
Warning: ibase_fetch_object(): supplied argument is not a valid InterBase
result resource in c:\program files\apache
