I have an Access database and a table. One of the columns was a memo
field. If I execute a 'select * from table', all the rows would be
retrieved but the columns after the memo column had null data.
If I moved the memo field to the end and executed the same SQL the data
was retrieved propery.
Also if I specified the column name by itself (E.g. select phone from
table' ), the data was retrieved.
Has anyone seen this kind of problem with any other databases where a
memo field must be the last one? 3 3694

Could it be something to do with the length?

It seems to happen with a short table too.
I am using PHP5.1 under Windows XP of course.
I made a small table and added 2 rows with info in all columns and here
is the layout:
LastName - text,
notes - memo,
addr - text,
zip - text
Here is the code. It fails in $cursor and $cursor1 but works when notes
is last in $cursor2.
<?php
$tbl='tblNotes' ;
$user='';
$pass='';
$conn = "DSN=mailing;Dr iver=Microsoft Access Driver";
try {
$dbh = new PDO("odbc:$conn ", $user, $pass);
// prints nulls after NOTES
$cursor=$dbh->query("SELEC T * from $tbl order by LastName");
foreach ($cursor as $row) {
$row=array_chan ge_key_case($ro w, CASE_UPPER);
echo $row['LASTNAME'] . '|';
echo $row['NOTES'] . '|';
echo $row['ADDR'] . '|';
echo $row['ZIP'] . '|';
echo "\n";
}
echo "\n";
// Also prints nulls after NOTES
$cursor1=$dbh->query("SELEC T LastName, notes, addr, zip from $tbl
order by LastName");
foreach ($cursor1 as $row) {
$row=array_chan ge_key_case($ro w, CASE_UPPER);
echo $row['LASTNAME'] . '|';
echo $row['NOTES'] . '|';
echo $row['ADDR'] . '|';
echo $row['ZIP'] . '|';
echo "\n";
}
echo "\n";
// prints all columns correctly because I moved notes to be last
$cursor2=$dbh->query("SELEC T LastName, addr, zip, notes from $tbl
order by LastName");
foreach ($cursor2 as $row) {
$row=array_chan ge_key_case($ro w, CASE_UPPER);
echo $row['LASTNAME'] . '|';
echo $row['NOTES'] . '|';
echo $row['ADDR'] . '|';
echo $row['ZIP'] . '|';
echo "\n";
}
} catch (PDOException $e) {
echo $e->getMessage() ;
}
$dbh = null;
?>
Result when you run this:
$cursor
doe|mm|||
smith|xx|||
$cursor1
doe|mm|||
smith|xx|||
$cursor2
doe|mm|120 main street|10006|
smith|xx|320 bway|10007|

That's a known limitation of ODBC I think. Once the driver goes into
blob retrieval mode, it can't retrieve fixed width columns anymore. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Is there somebody who could explain me how to make a connection to a access

We have been using ODBC connections that are in the registry of the computer. However these connections aren't in by default so when a new user uses the Access program or when a current user goes to a different computer, we have to send them the batch program to put the ODBC hooks on that machine.
We want to get around that by using Pass-Through queries and the ODBC connection string. What we have got to work is this:
