datetime as float
Is there any MySQL built in function to convert datetime types to real numbers (float) i.e. seconds or days since a reference date? I can't find any in the manual. If not, how do I best write a speedy one (conversion of calendar dates to Julian days is a bit tricky)?

Upgraded (?) to MySQL 3.23.52 and lost connection
Yesterday I upgraded (?) to MySQL 3.23.52 on two different machines and since then I get the message MyODBC 3.51 DataSource Test MySQL ODBC 3.51 Driver : 03.51.02 [MySQL][ODBC 3.51 Driver]Lost connection to MySQL server during query when I try to test the data source from windows with MyODBC 3.51. I get similar results from programs using the Zeos database components and my Roxen server refuses to connect. The mysqld is running on a freshly installed Red Hat Linux 8.0 and the mysql console program running on this machine functions normally. Is the new RH 8.0 or MySQL 3.23.52 to blame or can I be doing something wrong?

minimal SQL
I am new to databases and SQL and find the language rich and interesting. It seems to me, however, that there are quite a few redundant elements and that the language is the result of quite a few compromises. There are not less than 233 keywords in MySQL. Is there any preferred way to write SQL-statements? Is there any purist or minimalist view?

Functions as default values
Timestamp is a useful datatype when you want to register when a record changed. Now I want to register who changed it and tried to use user() as a default value and my database just returned user() as the field value. Is there someone who can tell me how to use a function result as default value? The manual is not very clear on this issue.

Illegal table names
By accident, I don't know how (perhaps microsoft played me a trick), I managed to create a table with a name containing spaces i. e. a useless table with an illegal name. Now would like to drop that table. Is there anyone who knows how?

Illegal table names
I am sending this again since for some reasons undescores don't show up in this forum. The third table name should read tentamen_impl_vt2001 i.e. tentamen[underscore]implunderscore]vt2001 which is legal.

Illegal table names
The character seems to be decimal 96 (enter it with Alt-96 on a PC). Interestingly the command produces an error when the command is given directly to mysql over a ssh connection but works fine when invoked with Zeos Simple_mysql (http://www.zeoslib.org/zeos_zia_main.php ).

slow MySQLGUI
My MySQLGUI running on a Windows system is invariably much slower(typically 30 seconds) than a MSAccess database with tables linked with MyODBC to the same Linux-hosted Mysql-database (typically less than 1 second) when executing the same query over a telephone internet connection. Why is that so?
