You should use "date" instead of "datetime" since the data is only a date and a "date" type uses less storage than a "timestamp".
For time only data use type "time" or "timetz" if you want the timezone as well. For data with a date and time use "timestamp" or "timestamptz" if you want to include the timezone as well.
I hope this is helpful. There are other time based data types as well but you should read the documentation to determine when it is best to use them.
One thing I really like about PostgreSQL is the variety of data types and functions for special operations on them.
## I believe the information below is correct.
If you go through the documentation you can also find out how to CREATE your own data TYPE to allow more direct use of non-PostgreSQL data types. Here is an example that will allow input of any "datetime" data into PostgreSQL :
CREATE TYPE datetime AS (datetime timestamptz);
Then any time,date or date and time data can be input as type datetime. Without having to convert your tables to rename the "datetime" type.

Can someone tell me how I can adjust the syntax of the code and in global: how can I convert sql-code , for microsoft sql server 2000, to sql-code for postgresql?
