howto connect to as400 with PHP

问题

I am trying to connect my AS400 with V5R3 with PHP using this code :

<?php
$server="Driver={Client Access ODBC Driver (32-bit)};System=xxx.xxx.xxx.xxx;
Uid=user;Pwd=password;"; #the name of the iSeries
$user="user"; #a valid username that will connect to the DB
$pass="password"; #a password for the username

$conn=odbc_connect($server,$user,$pass); #you may have to remove quotes

#Check Connection
if ($conn == false) {
echo "Not able to connect to database...<br>";
}

#Query the Database into a result set - 
$result=odbc_exec($conn,"SELECT * FROM LIBRARY.V5TDOC0L WHERE T§DTDO = 20120319");

if (!$result)
  {exit("Error in SQL");}
echo "<table><tr>";
echo "<th>T§NDOC</th>";
echo "<th>T§DTDO</th></tr>";
while (odbc_fetch_row($result))
  {
  $ndoc=odbc_result($result,2);
  $dtdo=odbc_result($result,3);
  echo "<tr><td>$ndoc</td>";
  echo "<td>$dtdo</td></tr>";
  }
echo "</table>";

#close the connection
odbc_close($conn);
?>

I got this error :

Warning: odbc_exec() [function.odbc-exec]: SQL error: [IBM][Programma di controllo ODBC di System i Access][DB2 per i5/OS]SQL0104 - Token � not valid. Token valid: < > = <> <= !< !> != >= �< �> �= IN IS NOT LIKE BETWEEN., SQL state 37000 in SQLExecDirect in F:\xampp\htdocs\php-as400\php-as400.php on line 25 Error in SQL

Removing from the statement SELECT the WHERE T§DTDO = 20120319, I have it running and listing the elements I want with a warning.

Line 30 is :

while (odbc_fetch_row($result))

I believe the problem is the character § as I found looking in internet (https://bugs.php.net/bug.php?id=47133), but I don't know how to solve it.

回答1:

I have never seen the character § used in a column name before. This might be a code page conversion issue. Ask the IBM i admin to verify the column name; it might really be T@DTDO, T#DTDO or T$DTDO - something you can actually type. Failing that, try enclosing the column name in double quotes: ...where "T§DTDO"=20120319... If that does not work, have the DB2 admin create a view with column names that don't have special characters in them.

回答2:

Try with the quotes:

$result=odbc_exec($conn,'SELECT * FROM LIBRARY.V5TDOC0L WHERE "T§DTDO" = 20120319');

回答3:

Character § and £ are the "italian-equivalent" of @ and #.

In italian CCSID (e.g. 280) you'll see (and use) the fields of V5TDOC0L in this way: T§TDOC, T§NDOC. In other CCSID (e.g. 37) you'll see T@TDOC and T@NDOC (for the same file!).

I don't know which ccsid will use the job serving the PHP page. It could depend on the system default.

Try with "SELECT * FROM LIBRARY.V5TDOC0L WHERE T@DTDO = 20120319"
