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...

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.
For more info see: http://docs.moodle.org/en/XMLDB_Roadmap (point 1)
