PHP Bug Type: ODBC related
Bug description: ODBC Column Name Truncation
Description:
------------
When retrieving ODBC results from Sybase SQL Anywhere 6 and 9, the column
names are being truncated to 31 characters.
This happens even if the column name is simply specified using sql 'AS'
(i.e. "select column as
a_really_long_name_that_is_longer_than_31_characters from crap" would
still return "a_really_long_name_that_is_long" as the column name).
Have tried in PHP 4 and 5, Win2K Server and SUSE Linux, all with same
results.
-- The buffer used by the odbc extension to store field
names is only 32 bytes.
Reproduce code:
---------------
<?php
$DBN = 'thedbn';
$UID = 'theuid';
$PWD = 'thepws';
$CONN = odbc_connect( $DBN, $UID, $PWD ) or die( "Cannot connect to
$DBN."); $sql = "select * from crap"; $result = odbc_exec( $CONN,
$sql );
for( $i = 1 ; $i <= odbc_num_fields( $result ) ; $i++ ) {
$name = odbc_field_name( $result, $i );
${$name} = odbc_result( $result, $name );
print( "$i: $name - ${$name}\n" );
}
?>
Expected result:
----------------
1: key - 4
2: a_really_long_name_that_is_longer_than_31_characters - 5
3: longer_name - 6
Actual result:
--------------
1: key - 4
2: a_really_long_name_that_is_long - 5
3: longer_name - 6
