-Hi Andrew,
-
-thanks a lot for your help. Today we discovered what
-our real problem was:
-
-After "playing" a little bit with the php-scripts that try
-to connect to the IBM DB2, we set the optional parameter
-Cursortype when calling odbc_pconnect(....).
-
-And the exciting thing: When we set the cursor type
-to SQL_CUR_USE_ODBC Cursor Type, then
-the whole query speed up from 1 till 10 seconds
-to 0.2 till 0.3 seconds for 100 records. Amazing!!!
-
-Therfore, PHP is just almost fast as calling the DB2
-from Servlets using JDBC (don't take too much care
-about the speed at whole: the database was on a
-completely other location, so the whole connection
-was made over a slow network connection).
-
-I hope this helps when other encounter the same
-problem when trying to connect to DB2 from
-PHP.
-
-Kind regards,
-Christian Szardenings

-2 Oct 2001
-Mark Newnham has discovered that the SQL_CUR_USE_ODBC is not supported by
-IBM's DB2 ODBC driver, so this must be a 3rd party ODBC driver.
-
-From the IBM CLI Reference:
-
-SQL_ATTR_ODBC_CURSORS (DB2 CLI v5)
-This connection attribute is defined by ODBC, but is not supported by DB2
-CLI. Any attempt to set or get this attribute will result in an SQLSTATE of
-HYC00 (Driver not capable).
-
-A 32-bit option specifying how the Driver Manager uses the ODBC cursor
-library.
-
-So I guess this means the message [above] was related to using a 3rd party
-odbc driver.
-
-Setting SQL_CUR_USE_ODBC
-========================
-To set SQL_CUR_USE_ODBC for drivers that require it, do this:
-
-$db = NewADOConnection('db2');
-$db->curMode = SQL_CUR_USE_ODBC;
-$db->Connect($dsn, $userid, $pwd);
-
-
-
-USING CLI INTERFACE
-===================
-
-I have had reports that the $host and $database params have to be reversed in
-Connect() when using the CLI interface. From Halmai Csongor csongor.halmai#nexum.hu:
-
-> The symptom is that if I change the database engine from postgres or any other to DB2 then the following
-> connection command becomes wrong despite being described this version to be correct in the docs.
->
-> $connection_object->Connect( $DATABASE_HOST, $DATABASE_AUTH_USER_NAME, $DATABASE_AUTH_PASSWORD, $DATABASE_NAME )
->
-> In case of DB2 I had to swap the first and last arguments in order to connect properly.
