Hi, I figured out part of my problem with the php script. The files I
was trying to access are too Old !
The script from "The IBM I Programmer's Guide to PHP", page 246 simply
retrieves the library/file name and then lists the names of the columns
(fields).
 
<?php
//Set the database name
$tableName = 'FILENAME' ;
$libName = 'LIBRARY' ;
 
//Create the connection to the System i Relational Database
if (($dbh = db2_connect('SYSTEM','USERID','PASSWORD')) === false) {
      echo 'connection failed.<br>' ;
      echo db2_conn_errormsg().'<br>' ;
      die() ;
}
 
//Retrieve a result set with the column info for the
//file specified at the top of the script.
if (($cols = db2_columns( $dbh, null, $libName, $tableName, '%' )) ===
FALSE) {
      echo 'colums retrieval failed. <BR>' ;
      echo db2_stmt_errormsg(). '<BR>' ;
      die() ;
}
 
//Fetch the first row and output the file name
// and library name from the result set.
$column = db2_fetch_assoc($cols) ;
echo 'FileTable: ' ;
echo $column["TABLE_SCHEM"]."/".$column["TABLE_NAME"]."<BR>" ;
 
//Loop thru all the result set rows and list all the column names.
 
do {
      echo $column["COLUMN_NAME"]."<BR>" ;
} while ($column = db2_fetch_assoc($cols)) ;
      
?>
 
Some files however, would not share their column information. I wouldn't
even get the name of the file or the library ! In talking to another
programmer, he said that some files could not be accessed via ODBC. When
I tried the files he had problems with the same thing happened. 
 
HOWEVER, if you copy the file to another library or even the same
library using a different name, it suddenly becomes visible to the php
script and to odbc. CPY and CRTDUPOBJ both seem to work, not rgzpfm or
chgpf. The files that are difficult are older files on our system,
generally created before 2000. 
 
Is this something anyone else has come across ?  Is there a PTF I should
be looking for ?  We are on an 810 at V5R4.
