94e65cc36c Now all the insert_record() and update_record() calls under 
Oracle DB use the oracle_dirty_hack() function to transform
empty strings into something different ' ' in order to avoid
the problems with the empty=NULL stupid norm of Oracle.

With this change, Oracle installation works completely.

Now we need to implement everywhere the opposite hack: transforming
all those ' ' (1 whitespace) back to the '' (empty string). Working
on it now.

0ce61c841f Force ANSI NULLs under mssql. It's not critical to work 
but it avoids some problems when changing nullability
of fields in the future.

d7e901c669 dmlib: changed array access to keyed instead of ordinal. 
This supports the move to ADODB_FETCH_ASSOC instead of ADODB_FETCH_BOTH.

3d5fb99f00 Fixed bug in get_records_sql(). This call: 
$rs = get_recordset_sql($sql, $limitfrom='', $limitnum='');

should really be:

$rs = get_recordset_sql($sql, $limitfrom, $limitnum);

e20d180c11 DIRTY HACK to convert back all the ' ' (1 space) field contents 
back to '' (empty string) in order to allow Oracle to work, more
or less until all the not real NOT NULL DEFAULT '' fields were out!

TODO: Apply the same hack to some more functions...

8351e29517 Introduced one function to calculate the proper "AS" 
keyword for columns. All DB seems to support it but
PostgreSQL require it!

3655a6b39f Set magic_quotes_sybase for both mssql and oci8po. 
Anyway, this isn't enough and if must be defined in php.ini
or .htaccess, because GPC are added BEFORE this setting
has effect so they are slashed with the default char.

d1c21c8f31 Very, very, very, very initial support of insert_record for oracle. 
I shouldn't interfere with the rest at all. I needed it in CVS now.

7e8f922047 Adding back the first column in the recordset, that is out after GetAssoc(), 
in order to:

- Don't get our first named column under some drivers.
- Be able to migrate to ADODB_FETCH_ASSOC soon.

For more info, http://docs.moodle.org/en/XMLDB_Problems,
in the  ADOdb fetch mode (ASSOC, NUM and BOTH) section.

293bccd539 First commit for the progressive adoption of ADODB's SelectLimit() function 
in order to support LIMIT clauses in a cross-db compatible way.
Changes don't affect old sentences at all (all them would be changed soon too).

7e13be0887 Splitting datalib.php in three libraries: 
- ddllib.php: Where all the DDL (install/upgrade) functions will be.
  - dmllib.php: Where all the DML (select...) functions will be.
  - datalib.php: Legacy lib. Its contents should go to other libraries soon.
