#43912 [Opn]: Interbase column names are truncated to 31 characters

ID: 43912 User updated by: virtue at rocketmonkeys dot com Reported By: virtue at rocketmonkeys dot com Status: Open Bug Type: InterBase related Operating System: Windows XP SP2 PHP Version: 5.2.5 New Comment: From the documentation with Interbase 8.1, object names can be up to 67 characters long, plus a NULL terminator. ---- Valid names for InterBase objects must use the 7-bit ASCII character set (character set ID 2) and must have the following characteristics: • no spaces • not case sensitive • not InterBase keywords • a maximum of 68 bytes long: 67 bytes plus a null terminator Previous Comments: ------------------------------------------------------------------------ [2008-01-22 21:14:13] virtue at rocketmonkeys dot com Description: ------------ The PHP interbase functions seem not to support column names that are longer than 31 characters with Interbase 8.1. Interbase 5.5 through 6.5 are supposedly limited to 31 character names, but later version are not. I can query the field with PHP using the full name. The correct value is returned, but the returned name is incorrectly truncated to 31 characters. The Interbase IBConsole program returns the correct field name, untruncated. Reproduce code: --------------- <? ibase_connect(...); ibase_query( "create table TEST1 ( A_________B_________C_________D_________E_________F_________ integer );" ); ibase_query( "insert into TEST1 values ( 1 );" ); $result = ibase_query( "select * from TEST1;" ); $object = ibase_fetch_object( $result ); var_dump( $object ); ?> Expected result: ---------------- object(stdClass)#2 (1) { ["A_________B_________C_________D_________E_________F_________"]=> int(1) } Actual result: -------------- object(stdClass)#2 (1) { ["A_________B_________C_________D"]=> int(1) } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43912&edit=1
